Description

  The present invention relates to a search system, and more particularly, to a search system for searching for a pet who has escaped from an owner's house, a deaf person who has gone out of the house and has difficulty in returning home.

  Recently, for example, a lost object detection system and a monitoring system have been developed using transmitters conforming to short-range wireless standards such as Bluetooth (registered trademark) and BLE (Bluetooth Low Energy).

  As an example of these, when the property to which a transmitter is attached is lost, the unique identification information transmitted by the transmitter is detected by an information terminal such as a smartphone owned by a third party other than the owner of the lost item. Then, the information terminal transmits the position information measured by using GPS or the like together with the detected unique identification information to the server device, and the server device stores in advance the unique identification information transmitted from the information terminal. Compared with multiple unique identification information, if there is a matching unique identification information, the location information measured by the third party information terminal to the information terminal owned by the owner of the lost item (searcher) A lost object detection system for notification is known (Patent Document 1).

  As another example, a protected person possesses a transmitter, and an information terminal provided in the vicinity of a route through which the protected person travels detects unique identification information transmitted by the transmitter. Is transmitted to the server device together with the position information measured by the information terminal, so that the position information notification system that notifies the parent terminal of the position information until the child who attends the school or cram school arrives at the destination is known. (Patent Document 2).

Japanese Patent No. 5894309 Japanese Patent No. 5891468

  According to Patent Literature 1, it is possible to eliminate the time and labor required for the searcher himself / herself to search for the lost object by omitting the need for the searcher himself / herself to visit the site to find the lost object. In Patent Document 1, even if persons using the application software of this service are within a certain distance range, the inconvenience that the position information is transmitted each time does not occur. Therefore, “location information will not be transmitted unless the user who owns the lost item is set to be lost”.

  If the object to be searched is an object, the concept of “watching” is not normally generated for the object, so it is meaningful to restrict location information from being sent to the user unless it is set as described above. There seems to be. However, there is a need to confirm that the target is close to the user as necessary, for example, in a target that is desired to be observed on a daily basis, such as a pet or an elderly person who may be jealous. However, with the configuration disclosed in Patent Document 1, it is difficult to provide such a service.

  Further, according to Patent Document 2, in a situation where a subject to be protected such as schoolchildren is going to and from school, for example, position information of a plurality of points while moving between a home and a destination (such as an information terminal owned by a third party) It is said that parents can confirm from time to time.

  However, although the location information of a plurality of points is measured by information terminals arranged in the vicinity of the travel route to the target destination requiring protection, these information terminals only measure the location information and notify the server device. It is not assumed that any third party other than the guardian actively participates in the search when an unforeseen situation occurs in the object requiring protection. This also applies to Patent Document 1.

  The present invention has been devised to solve such problems of the prior art, and its main purpose is possessed by parents and third parties in situations where a search for the object to be protected is required. An object of the present invention is to provide a search system capable of accurately collecting position information of an object using an information terminal and confirming that an object to be protected exists in the vicinity of the user even in a situation where no search is required.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram showing an overview of a search system S1 according to the first embodiment of the present invention.

  In FIG. 1, reference numeral 1 denotes an object requiring protection such as a pet. Hereinafter, the description will be made assuming a pet such as a domestic cat as the protection target 1, but the protection target 1 may be an elderly person who may be jealous or a child who is worried about getting lost.

  Reference numeral 2 denotes a transmitter attached to the protection target 1. The transmitter 2 includes a small power source (not shown) such as a button battery, and is configured to be small so that it can be carried using a holding member (not shown) such as a belt on the neck or limb of a pet. . Of course, the transmitter 2 may include a power source based on energy harvesting technology and be embedded in the body of the protection target object 1. The transmitter 2 is a radio beacon for transmitting / transmitting unique identification information (details will be described later) of the transmitter 2 stored in advance in an internal storage means (not shown). This corresponds to a device called Beacon (hereinafter, the transmitter 2 may be called “Beacon”). The reach distance DIS of the radio wave transmitted by the transmitter 2 (hereinafter, the range in which the radio wave reaches may be referred to as “reachable area”) is about 20 to 30 m. Depending on the environmental conditions, the reach distance DIS may reach about 50 m. The transmitter 2 incorporates a predetermined control unit (not shown), and the transmitter 2 transmits unique identification information at a predetermined cycle under the control of the control unit.

  Reference numeral 3 denotes a guardian who watches or searches for a target 1 to be protected. Reference numeral 4 denotes a first information terminal. When the first information terminal 4 carried by the guardian 3 enters the radio wave range transmitted by the transmitter 2, the first information terminal 4 receives the unique identification information transmitted from the transmitter 2. Reference numeral 5 denotes a network such as the Internet. Reference numeral 6 denotes a server device.

  The first information terminal 4 is configured to be able to measure the position information where the first information terminal 4 exists based on the data transmitted from the GPS satellite 7, and the unique information received from the measured position information and the transmitter 2. The identification information is transmitted to the server device 6 via the network 5. The server device 6 compares the received unique identification information with a plurality of pieces of unique identification information stored in advance, and if matching unique identification information is detected, the position measured by the first information terminal 4 Information is transmitted to the first information terminal 4. In response to this, the first information terminal 4 carried by the guardian 3 displays the fact that the transmitter 2 (that is, the subject of protection 1 carrying the transmitter 2) has been discovered, and the discovered location information. The

  For example, in the case where the pet escapes from the house and the guardian 3 who carries the first information terminal 4 searches for the pet, the guardian 3 moves from the point A (not within the reach of the radio wave transmitted by the transmitter 2). When moving to B (within the coverage area of the radio wave transmitted by the transmitter 2), the first information terminal 4 receives the unique identification information transmitted by the transmitter 2, and receives the identification information unique to the server device 6 and the first identification information. The position information measured by the information terminal 4 is transmitted to the server device 6 (actually, time information is also transmitted to the server device 6. Details will be described later). The server device 6 transmits the position information received from the first information terminal 4 to the first information terminal 4. That is, the guardian 3 receives the position information where the protection target 1 is found from the server device 6. As a result, the guardian 3 can know that the object 1 requiring protection is in the vicinity of him / her.

  FIG. 2 is a block configuration diagram showing the configuration of the first information terminal 4 in the first embodiment of the present invention. Hereinafter, the configuration of the first information terminal 4 will be described.

The first input unit 15 is a user interface of the first information terminal 4 and includes, for example, a touch panel that detects that the user has touched or hovered the panel surface by detecting a change in capacitance.

  The first terminal control unit 16 includes a processing unit (CPU: Central Processing Unit), a Flash memory, a RAM (Random access memory), and the like (none of which are shown), and is configured according to predetermined application software stored in the Flash memory. Control the components. The terminal storage unit 17 is composed of, for example, a Flash memory, and is configured to be accessible from the first terminal control unit 16. The display unit 18 includes, for example, an LCD (liquid crystal display), an OLED (Organic Light Emitting Diode) panel, and a driver. The display unit 18 may be arranged so as to overlap with the first input unit 15. The radio wave intensity measuring unit 19 measures a received signal strength indicator (RSSI) received by the first information terminal 4 from the transmitter 2.

  First, the information transmitted by the transmitter 2 will be described in detail. The transmitter 2 includes a communication module (not shown) compliant with, for example, the Bluetooth Low Energy (BLE) standard, and transmits unique identification information periodically (for example, every 5 to 10 seconds). The unique identification information is generally composed of three identifiers called proximity UUID, major, and minor.

  The proximity UUID is expressed by a 128-bit UUID (Universally Unique Identifier), and is used as an identifier of a corporation / organization or the like or a service provided by them. The data advertised by Beacon (i.e., transmitter 2) always includes a proximity UUID. Major is a value expressed in 16 bits, and is used as a unique identifier for each Beacon having the same proximity UUID. minor is a value expressed in 16 bits and is used as a Beacon identifier having the same proximity UUID and major. In the BLE standard, whether or not major and minor are included in information advertised by Beacon is arbitrary, but in the search system S1 according to the first embodiment, beacon includes at least proximity UUID and major. To be able to identify individual beacons.

The short-range wireless communication unit 10 includes, for example, a receiving module (not shown) conforming to the BLE standard, and when receiving information advertised by the transmitter 2, values of proximity UUID, major, and minor (that is, unique identification information) And an interrupt signal is output to the first terminal control unit 16. When the first terminal control unit 16 receives the interrupt signal, it may be referred to as time information (hereinafter referred to as “terminal time information”) from a built-in clock module (not shown). The time information T _ble and the terminal time information T _gps ) are acquired, the short-range wireless communication unit 10 is accessed, the unique identification information of the transmitter 2 is taken in, and the short-range wireless communication unit 10 outputs an interrupt. The terminal time information T _ble at the time of occurrence of the interrupt based on the signal and the unique identification information are stored in the terminal storage unit 17. Note that the short-range wireless communication unit 10 may further include a transmission module (not shown) to support bidirectional communication.

The first position information acquisition unit 11 receives GPS data transmission times, satellite orbit data, and the like transmitted from a plurality of GPS satellites 7, and includes latitude / longitude information (position information) where the first information terminal 4 exists by three-dimensional positioning. ) Is calculated. This calculation uses a high-speed calculator built in the first position information acquisition unit 11, and the first position information acquisition unit 11 performs the calculation of the latitude / longitude information to the first terminal control unit 16. Output an interrupt signal. When receiving the interrupt signal, the first terminal control unit 16 stores the terminal time information T _gps and the latitude / longitude information at the time of occurrence of the interrupt based on the interrupt signal output from the first position information acquisition unit 11 in the terminal storage unit 17. .

Further, when receiving the interrupt signal from the short-range wireless communication unit 10, the first terminal control unit 16 stores the terminal time information T _gps and the latitude / longitude information acquired from the first position information acquisition unit 11 immediately before the interrupt signal. The data is extracted from the unit 17 and output to the data transmission unit 12 together with the unique identification information extracted by the short-range wireless communication unit 10. The latitude / longitude information output to the data transmission unit 12 may be processed based on the setting of the mode setting unit 14 described later. As an example of this processing, using the terminal time information T _gps and the terminal time information T _ble , a plurality of position information and time information (terminal time information T _gps ) acquired in the past by the first position information acquisition unit 11 For example, estimating the position information of the first information terminal 4 at the time (terminal time information T _ble ) when the short-range wireless communication unit 10 receives the unique identification information.

The data transmission unit 12 includes a mobile communication module that supports, for example, LTE (Long Term Evolution) / 3G and the like, connects the first information terminal 4 and the network 5 using a wireless line, and the first terminal control unit 16 Terminal time information T _gps , latitude / longitude information, and unique identification information (hereinafter sometimes referred to as “time / position and unique identification information”) input to the server device 6 via the network 5. Send.

The server device 6 extracts unique identification information from the received time / position and unique identification information, and checks whether the unique identification information is stored in the server storage unit 33 (see FIG. 3). If stored, the latitude / longitude information and the terminal time information T _gps (hereinafter sometimes referred to as “protection target position information etc.”) are used for the first information terminal 4 (for example, the mail of the guardian 3). Address). At this time, the fact that the protection target 1 is found may be transmitted in a flag format. The frequency at which the data transmission unit 12 transmits the time / position and unique identification information to the server device 6 is adjusted based on the setting of the mode setting unit 14 described later. The data transmission unit 12 may transmit the time / position and unique identification information to the server device 6 via a wireless LAN such as WiFi (Wireless Fidelity).

  The data receiving unit 13 of the first information terminal 4 receives the protection target position information transmitted from the server device 6 and outputs an interrupt signal to the first terminal control unit 16. The first terminal control unit 16 that has received the interrupt signal rings, for example, a ringing tone, and displays on the display unit 18 that the protection target 1 has been found, the time of discovery, and the location of discovery. Of course, the received position information to be protected may be sequentially stored in the terminal storage unit 17, and the history of the found positions may be displayed on a map.

  FIG. 3 is a block configuration diagram showing the configuration of the server device 6 in the first embodiment of the present invention. Hereinafter, the configuration and functions of the server device 6 will be described with reference to FIG.

  As illustrated in FIG. 3, the server device 6 includes a server data reception unit 30, a server data transmission unit 31, a server control unit 32, and a server storage unit 33. Each of these components is coupled by a server data bus 34. The server device 6 is wired or wirelessly connected to the network 5 and exchanges data with the first information terminal 4 in both directions via the network 5.

  When the server data receiving unit 30 receives the time, position, and unique identification information transmitted from the data transmitting unit 12 (see FIG. 2) of the first information terminal 4, the server data receiving unit 30 notifies the server control unit 32 of the received information. Store in the server storage unit 33.

  The server data transmission unit 31 is controlled by the server control unit 32 and transmits the protection target position information and the like to the first information terminal 4 via the network 5.

  The server control unit 32 includes a processing unit (CPU: Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), etc. (all not shown), and has other configurations according to a control program stored in the ROM. Control elements.

  The server storage unit 33 is a so-called large-capacity storage having a RAID (Redundant Arrays of Independent Disks) configuration or the like. In the server storage unit 33, a guardian database PDB and a guest database GDB (both described later) are constructed, and search history information (described later) and the like are further accumulated.

  FIG. 4 is an explanatory diagram showing an overview of the guardian database PDB and the guardian record PREC constituting the guardian database PDB in the first embodiment of the present invention. Hereinafter, the data structure of the guardian database PDB will be described with reference to FIGS. 3 and 2 in FIG.

  In the server storage unit 33, a guardian database PDB is stored in which the guardian records PREC_0 to PREC_N shown in FIG. 4 are stored (hereinafter, when individual records are not specified, “guardian record PREC”). Sometimes called). There are at least as many guardian records PREC as there are transmitters 2 (in this case, N + 1) supplied to the market.

  Hereinafter, the data structure of the guardian record PREC will be described. The guardian record PREC is a record in which information on the transmitter 2 owned by the guardian 3, information on the guardian 3 itself, a file pointer of a profile related to the protection target 1 created by the guardian 3, and the like are described. In FIG. 4, a guardian record PREC_0, a guardian record PREC_1, a guardian record PREC_X, and a guardian record PREC_N are records corresponding to the transmitter 2 already used by the guardian 3, and other guardian records PREC. Is a record corresponding to the transmitter 2 that is not yet used.

  A unique serial number (may be a serial number or the like) corresponding to each transmitter 2 supplied to the market is stored in Field 1 of the guardian record PREC. Field 2 stores unique identification information corresponding to the transmitter 2 on a one-to-one basis. That is, Field 1 and Field 2 are unique information associated with a specific transmitter 2. In Field 3, the contact information of the owner of the transmitter 2 (usually the guardian 3), that is, the mail address of the first information terminal 4 possessed / carried by the guardian 3 (hereinafter referred to as “contact information”). Stored). Field 4 stores link information (file pointer) indicating a storage position of a profile (name, photo, feature, introduction sentence, etc.) relating to a pet or the like.

  In a state where the guardian 3 has not yet used the transmitter 2 after purchasing it, NULL is stored in Field 0 and Field 3 to Field 5 as shown in the guardian record PREC_2, for example. When the use of the transmitter 2 is started, the guardian 3 operates the first information terminal 4, so that information related to the transmitter 2 owned by the guardian 3, information about the guardian 3 itself, etc. is stored in the server device 6. Transmitted and significant information is written into these fields.

  FIG. 5 is a flowchart showing a process of updating the guardian record PREC in the first embodiment of the present invention. Hereinafter, the registration process of the transmitter 2 performed by the guardian 3 operating the first information terminal 4 will be described with reference to FIGS.

  First, when the guardian 3 as a user of the search system S1 installs dedicated application software (hereinafter sometimes simply referred to as “dedicated application”) on the first information terminal 4 and starts it, the dedicated application is It becomes resident in the first information terminal 4 and can receive advertisements transmitted by the transmitter 2 as Beacon. Next, when the guardian 3 attaches a button battery or the like to the transmitter 2, the transmitter 2 starts advertising at a predetermined cycle. In this state, the first terminal control unit 16 extracts the proximity UUID, major, and minor, which are unique identification information of the transmitter 2, from the received advertisement, and determines the service name (dedicated application) of the predetermined search system S1. It is determined whether or not the proximity UUID matches (ST001). If the service name of search system S1 matches the unique identification information (Yes in ST001), the process proceeds to ST002. If they do not match (No in ST001), the process ends.

  Next, the first terminal control unit 16 switches the display of the display unit 18 to a serial number (hereinafter, sometimes referred to as “first code information”) input screen, and the guardian 3 is placed in the first input unit 15 by the first terminal. When 1 code information is input (ST002), the first terminal control unit 16 extracts contact information such as the mail address of the guardian 3 from the terminal storage unit 17 and controls the data transmission unit 12 to control the first code information and Contact information is transmitted to server device 6 via network 5 (ST003). At this time, a proximity UUID that is an identifier representing the service may be transmitted at the same time. The server device 6 searches the guardian database PDB using the received first code information as a key, and stores the received contact information in Field 3 of the guardian record PREC including the corresponding first code information. As a result, the serial number and unique identification information previously stored in the guardian record PREC are associated with the contact information of the guardian 3 newly added to the guardian record PREC.

  As described above, in the search system S1 of the first embodiment, when the transmitter 2 is registered in the guardian database PDB, the guardian 3 is requested to input the first code information. The reason for this is that, firstly, the easy registration process by only the actions of installing the dedicated application on the first information terminal 4 and attaching the button battery to the transmitter 2 is suppressed, and the search system S1 by the guardian 3 Second, to make it easier for a third party other than the guardian 3 (hereinafter sometimes referred to as a “guest”) to actively participate in the search for pets, etc. Because. In addition, the process which makes a guest participate in search of pets etc. is demonstrated later.

  Next, the first terminal control unit 16 switches the display on the display unit 18 to the pet information input screen, and the guardian 3 follows the guidance on the screen to the first input unit 15 for pet information such as name, photo, feature, introduction text, etc. (Profile) is input (ST004). The first terminal control unit 16 controls the data transmission unit 12 to transmit the profile to the server device 6 together with the already acquired first code information (ST005). The server control unit 32 of the server device 6 stores the received profile in the server storage unit 33 and acquires the file pointer. Further, the server control unit 32 searches the guardian database PDB using the first code information as a key, and stores a file pointer as link information in the field 4 of the guardian record PREC including the corresponding first code information. As a result, the serial number and unique identification information previously stored in the guardian record PREC are associated with the link information newly added to the guardian record PREC.

Hereinafter, the description will be continued by using FIG. 3, FIG. 2, FIG. 4 together with FIG.
When the server data receiving unit 30 receives the time / position and unique identification information from the first information terminal 4, the server data receiving unit 30 notifies the server control unit 32 to that effect. Upon receiving the notification, the server control unit 32 extracts the terminal time information T _gps , the latitude / longitude information, and the unique identification information and stores them in a predetermined area of the server storage unit 33 (hereinafter, the stored information is “searched” In addition, the parent database PDB is searched using the unique identification information as a key. In addition, the guardian 3 can access the search history information as needed by operating the first information terminal 4, and the first information terminal 4 Captures location history and displays it overlaid with map information.

As a result of searching the guardian database PDB using the unique identification information as a key, if a guardian record PREC storing the same unique identification information is detected, the server control unit 32 stores the guardian record PREC in the field 3 of the guardian record PREC. The contact information is taken out, the server data transmission unit 31 is controlled to designate the contact information as a transmission address, and the first information terminal 4 is supplied with the terminal time information T _gps and the latitude / longitude information (that is, the protection target required). Position information, etc.), and a flag indicating that the protection target 1 is found as necessary. As a result of the search, when a guardian record PREC in which the same unique identification information is stored cannot be found, predetermined error processing may be performed, or special processing may not be performed.

The first terminal control unit 16 of the first information terminal 4 that has received the protection target position information or the like via the data reception unit 13 discovers the protection target 1 by driving a speaker or a vibrator (both not shown). Notifying the guardian 3 of the fact that the map data published to the cloud 8 is acquired via the network 5 based on the latitude / longitude information, and the marker indicating the latitude / longitude information is set to the corresponding coordinate position of the map. Is displayed on the display unit 18. In this case adjacent to the marker may be displayed terminal time information T _gps, guardian 3 may be displayed terminal time information T _gps when tap marker.

  Hereinafter, the setting performed by the mode setting unit 14 of the first information terminal 4 and the operation of the first information terminal 4 according to the setting will be described with reference to FIG. The guardian 3 can operate the first input unit 15 and select the setting of the mode setting unit 14 from at least “search mode” and “watching mode”. Here, the “search mode” is a mode selected when searching for the protection target 1 whose location is unknown, and the “watch mode” means that the search for the protection target 1 is required. It is a mode that is selected when it is confirmed whether or not the protection target object 1 exists in the vicinity of the guardian 3. The first information terminal 4 is set to the “search mode” immediately after the guardian 3 starts up after installing the dedicated application described above, that is, in the initial state.

  In a state in which the “search mode” is set, the first terminal control unit 16 transmits time / position information and unique identification information to the server device 6 every time unique identification information is received from the transmitter 2. Thus, in the “search mode”, reception of unique identification information and transmission of time / position information and unique identification information to the server device 6 correspond to 1: 1.

  According to the “search mode”, when the guardian 3 arrives within the reach of the radio wave transmitted by the transmitter 2 carried by the pet, for example, when the pet escapes from the house, the guardian 3 carries the first 1 Information terminal 4 is surely notified of the location information where the protection target 1 is found. As described above, the transmitter 2 as a so-called Beacon transmits unique identification information in a relatively short period of, for example, 5 to 10 seconds, so that the relative distance between the pet and the guardian 3 is relatively large. Even in this case, it is easy to search for the protection target 1. In addition, the 1st information terminal 4 is provided with the electromagnetic wave intensity measurement part 19, and when the pet is discovered, the guardian 3 can grasp | ascertain the approximate direction where the protection required target 1 exists.

  The guardian 3 can switch the setting of the mode setting unit 14 to the “watching mode” by operating the first input unit 15 when searching for the protection target 1 is not required. When the “watching mode” is set, the first terminal control unit 16 of the first information terminal 4 receives the unique identification information transmitted from the transmitter 2 and receives the time / position and the unique identification information. Is temporarily suspended from transmission to the server device 6. That is, the first terminal control unit 16 receives the unique identification information by the short-range wireless communication unit 10 during a predetermined period TS (for example, the predetermined period TS = 3 hours. The predetermined period TS can be changed). If the accumulated number of receptions is M (M is an integer equal to or greater than 1), the time / position and unique identification information are transmitted to the server device 6 every time the predetermined period TS elapses. In response to this, the server device 6 returns the protection target position information and the like to the first information terminal 4. Note that when “watch mode” is set, it is usually assumed that the protection target 1 is near the guardian 3, so that a marker or the like based on latitude / longitude information in particular may not be displayed. .

Further, the processing content may be changed according to the number of unique identification information detected within the predetermined period TS, and further according to the time (terminal time information T _ble ) when the unique identification information is received from the transmitter 2. The processing content may be changed. That is, if the unique identification information is not received in the second half of the predetermined period TS (for example, when the predetermined period TS is 3 hours, the latter half of the hour), the protection target 1 is in the vicinity of the guardian 3. It may be suggested that there is no possibility.

  On the other hand, when the number of receptions accumulated in the predetermined period TS is 0, that is, when the protection target 1 is not found in the predetermined period TS, the first terminal control unit 16 transmits the time / position and unique identification information to the server device 6. Without driving, the speaker or vibrator is driven to notify the guardian 3 that the protection target 1 cannot be found in the predetermined period TS. Further, the display unit 18 displays that there is a possibility that the protection target 1 may not exist in the vicinity of the guardian 3. As a result, the first information terminal 4 carried by the guardian 3 periodically displays whether or not the object 1 requiring protection is present every time the predetermined period TS elapses. Even in situations where it is not necessary, it is possible to confirm whether or not the object 1 requiring protection is present, that is, to watch over the object 1 requiring protection.

  In the “watch mode”, the reception of the unique identification information and the transmission of the time / position and the unique identification information to the server device 6 are M: 1 (M is an integer of 1 or more), and the server device 6 In some cases, no time / position and unique identification information are transmitted. Of course, the guardian 3 can switch the setting of the mode setting unit 14 from “watch mode” to “search mode” by operating the first input unit 15 when searching for the protection target 1 is required.

  As described above, in the search system S1 according to the first embodiment of the present invention, the first information terminal 4 is necessary when the setting of the mode setting unit 14 is set not to search for the protection target 1 (watch mode). Compared to the case where the setting is made to search for the protection target 1 (search mode), the server device 6 receives the unique identification information and the position information (time / position and unique identification information) of the first information terminal 4. Reduce the frequency of transmission (minimum frequency is 0).

  Upon receiving the unique identification information and the position information (time / position and unique identification information) of the first information terminal 4 from the first information terminal 4, the server device 6 receives the position information (required) of the first information terminal 4. (Protection target position information etc.) is transmitted to the first information terminal 4.

  In the first embodiment, the first information terminal 4 has a unique information transmitted from the transmitter 2 when the setting of the mode setting unit 14 is set to search for the protection target 1 (search mode). Each time the identification information is received, the unique identification information and the position information of the first information terminal 4 are transmitted to the server device 6, and the setting of the mode setting unit 14 is set not to search for the protection target 1 (watch mode). When the unique identification information transmitted from the transmitter 2 is received, the transmission of the unique identification information and the position information of the first information terminal 4 to the server device 6 is temporarily suspended.

  In addition, when the setting of the mode setting unit 14 is set to not search for the protection target 1 (watch mode), the first information terminal 4 has a unique identification transmitted from the transmitter 2 within the predetermined period TS. The number of times information is received is accumulated, and if the accumulated number of receptions is 1 or more, the unique identification information and the position information of the first information terminal 4 are transmitted to the server device 6 every time the predetermined period TS elapses. .

  In the “search mode” and the “watching mode”, when the time / position and unique identification information are transmitted from the first information terminal 4 to the server device 6, the server device 6 always sends the information to the first information terminal 4. In response to this, information on the position to be protected is returned. However, depending on the convenience of the guardian 3, there may be a situation in which notification of position information or the like of the protection target 1 is not desired in a scene where the protection target 1 is watched or searched. Therefore, in the first embodiment, when the guardian 3 inputs the display permission / prohibition to the first input unit 15 in each of the “search mode” or the “watching mode”, the first terminal control unit 16 is protected. In accordance with an instruction from the user 3 (user), it is controlled whether or not to display the position information and the like of the first information terminal 4 (protection target position information and the like) transmitted from the server device 6.

  In the search system S1 of the first embodiment, when the mode setting unit 14 is set not to search the protection target 1 (watch mode), the first information terminal 4 sends the time / position and the server device 6 to the server device 6. Since the frequency of transmitting unique identification information is reduced, the load on the server device 6 can be significantly reduced.

  Now, in the usage scene of “watch mode”, the guardian 3 (that is, the first information terminal 4 owned by the guardian 3) is usually present in the vicinity of the protection target 1 and the guardian 3 The biggest concern is not the location information of the protection target 1 but first “whether the protection target 1 exists in the vicinity of the guardian 3”, and then “the time when the protection target 1 was discovered, In particular, it is considered to be “the last discovered time”.

  From this point of view, in the “watch mode”, the first information terminal 4 accumulates the number of times the unique identification information is received from the transmitter 2 within a predetermined period, and even if the accumulated number is 1 or more, the time / position and Each time the predetermined period TS elapses without transmitting unique identification information to the server device 6, the cumulative number of times and the time when the protection target 1 was discovered (in particular, the time when it was last discovered) are displayed on the display unit 18. You may make it display. Even in such a configuration, the transmission of the time / position and unique identification information to the server device 6 in the “watch mode” is zero. Of course, when it is desired to leave a history relating to watching of the protection target 1 in the server device 6, the time / position and unique identification information may be transmitted to the server device 6.

Hereinafter, modified examples of the first embodiment will be described.
In the modified example, when the setting of the mode setting unit 14 is set not to search the protection target 1, when the unique identification information is not received from the transmitter 2 during the predetermined period TS, The 1 information terminal 4 extracts the unique identification information stored in the terminal storage unit 17 and transmits it to the server device 6. Of course, the time / position and unique identification information may be transmitted to the server device 6. In addition, in a modification, it can grasp | ascertain early that the protection required object 1 was not near the guardian 3 by setting the predetermined period TS to 1 to several minutes.

  Thus, in a modification, the 1st information terminal 4 sets the mode setting part 14 which sets whether to search the protection required target 1, and the 1st position information acquisition part which acquires the positional information on the 1st information terminal 4 11. When having the terminal storage unit 17 for storing the unique identification information and when the setting of the mode setting unit 14 is set to search for the protection target 1, the unique identification information transmitted from the transmitter 2 Is received, the unique identification information and the position information of the first information terminal 4 are transmitted to the server device 6, and when the setting of the mode setting unit 14 is set not to search the protection target 1, the predetermined period TS If the unique identification information is not received from the transmitter 2 during this period, the unique identification information stored in the terminal storage unit 17 is transmitted to the server device 6.

(Second Embodiment)
Hereinafter, a second embodiment of the present invention will be described with reference to the drawings. FIG. 6 is an explanatory diagram showing an overview of the search system S2 according to the second embodiment of the present invention. In the following description, the same reference numerals are used for the same components as those of the first embodiment, and the description of the components is omitted.

  In the first embodiment described above, the search system S1 suitable for the guardian 3 himself to search for and monitor the protection target 1 such as a pet has been described. In the second embodiment, a search system S2 that allows a third party (guest) other than the guardian 3 to participate in the search will be described. In the following description, the search system S2 includes the search system S1, but the search systems S1 and S2 may exist independently.

  In FIG. 6, 40a and 40b are guests (hereinafter, the guests 40a and 40b may be referred to as guests 40 if they are not distinguished). The guest 40 is a person who searches for the protection target 1 other than the guardian 3. In FIG. 6, it is assumed that the guest 40a carries the second information terminal 50a and the guest 40b carries the second information terminal 50b (hereinafter, the second information terminal 50a and 50b are not distinguished from each other). 50.) In the following description, two guests 40a and 40b are assumed. However, the number of guests 40 may be larger or one.

  FIG. 7 is a block configuration diagram showing the configuration of the second information terminal 50 in the second embodiment of the present invention. Hereinafter, the description will be continued with FIG. In FIG. 7, 51 is a second position information acquisition unit, 55 is a second input unit, and 56 is a second terminal control unit. The second position information acquisition unit 51 acquires the position information of the second information terminal 50 and has the same function as the first position information acquisition unit 11 of the first information terminal 4. The second input unit 55 has the same function as the first input unit 15 of the first information terminal 4, and the second terminal control unit 56 has the same function as the first terminal control unit 16 of the first information terminal 4. . Note that the other components of the second information terminal 50 are substantially the same as those of the first information terminal 4, and description thereof is omitted here.

  When the guest 40 as a user of the search system S2 installs and activates the dedicated application on the second information terminal 50, the dedicated application resides in the second information terminal 50 and receives the advertisement transmitted by the transmitter 2 as Beacon. It becomes possible.

  Furthermore, in this state, the guest 40 can access the link information referred to by the field 4 of each parent record PREC in the parent database PDB and browse the profile of the pet or the like.

  When the guest 40a moves from the point C to the point D in the state where the dedicated application is activated and reaches the coverage area of the radio wave transmitted by the transmitter 2, the second information terminal 50a transmits the unique identification transmitted by the transmitter 2. The information is received, and the time / position and unique identification information are transmitted to the server device 6. Note that the second information terminal 50 is set to the “search mode” in the initial state in which the guest 40 activates the dedicated application. Accordingly, the second information terminal 50 stores the time / position and unique identification information at the same frequency as when the setting of the mode setting unit 14 of the first information terminal 4 is set to search for the protection target 1. Transmit to device 6.

  The server device 6 stores the received time / position and unique identification information as search history information in the server storage unit 33, searches the already-explained guardian database PDB (see FIG. 4), and receives the received unique identification. The guardian record PREC in which the information is stored is extracted, and based on the contact information stored in the guardian record PREC, the position information requiring protection is transmitted to the first information terminal 4 possessed by the guardian 3. . On the other hand, since the guest 40b and the guardian 3 who have not reached the reach of the radio wave transmitted by the transmitter 2 do not receive the unique identification information advertised by the transmitter 2, the above processing is not performed.

  Thus, the search system S2 according to the second embodiment further includes the second information terminal 50, and the second information terminal 50 acquires the second position information acquisition unit 51 that acquires the position information of the second information terminal 50. When the unique identification information transmitted from the transmitter 2 is received, the unique identification information and the position information (time / position and unique identification information) of the second information terminal 50 are transmitted to the server device 6. 2 The information terminal 50 displays the time / position and unique identification information at the same frequency as when the setting of the mode setting unit 14 of the first information terminal 4 is set to search for the protection target 1 (search mode). When the server apparatus 6 receives the time / position and unique identification information from the second information terminal 50, the server apparatus 6 receives the position information (protection target position information, etc.) of the second information terminal 50 as the first information. Transmit to terminal 4.

  At this time, the guest 40a transmits time / position and unique identification information from the second information terminal 50a possessed by the person to the server device 6, but actively participates in the search for the protection target 1 required. (Hereafter, the guest 40 in this state may be referred to as a “passive searcher”). That is, it is only the guardian 3 who actively searches for the protection target 1 and the guest 40a who is a passive searcher only provides the guardian 3 with the location information etc. where the protection target 1 is found. Absent.

  FIG. 8 is an explanatory diagram illustrating the guest database GDB, the outline of the guest record GREC constituting the guest database GDB, and the relationship with the guardian record PREC in the second embodiment of the present invention. FIG. 9 is a flowchart showing the registration procedure of the guest database GDB in the second embodiment of the present invention. Hereinafter, the process of actively participating the guest 40 in the search for the protection target object 1 will be described with reference to FIGS.

  In the server storage unit 33 of the server device 6, in addition to the guardian database PDB described above, a guest database GDB storing guest records GREC_0, GREC_1,... Shown in FIG. (When the record is not specified, it may be referred to as “guest record GREC”.) In the guest record GREC, guests 40 who actively participate in the search for the protection target object 1 using the search system S2 are registered. In the following description, a person who transmits the time / position and unique identification information from the second information terminal 50 possessed by the person to the server device 6 and actively participates in the search for the protection target 1 May be referred to as an “active searcher”.

  Hereinafter, the data structure of the guest record GREC will be described. The guest record GREC is a copy of information related to the transmitter 2 owned by the guardian 3, information related to the guest 40, a copy of a file pointer of a profile related to the protection target 1 created by the guardian 3, and a link to the guardian record PREC. A record in which information (file pointer) or the like is described. In FIG. 8, two records of guest record GREC — 0_1 and guest record GREC — 0_2 are described, but guest record GREC is added each time there is a registration process as an active searcher. Of course, when the active searcher stops cooperating with the search for the protection target 1, the guest record GREC is deleted by transmitting a predetermined command from the second information terminal 50.

  Hereinafter, a registration process for registering the guest 40 as an active searcher will be described. It is assumed that a dedicated application that provides the search system S2 service is installed and activated on the second information terminal 50 owned by the guest 40. Based on the dedicated application, the second terminal control unit 56 of the second information terminal 50 controls each component.

  First, the guardian 3 sends a mail system, for example, to the second information terminal 50 owned by the guest 40 (at this point, the guest 40 is a passive searcher) who wants to cooperate in the search for the protection target 1. Etc. is used to transmit the first code information as the serial number of the transmitter 2 (ST101). Upon receiving the first code information, the guest 40 operates the second input unit 55 of the second information terminal 50 according to the guidance displayed on the display unit 18 of the second information terminal 50, and contacts such as the mail address of the guest 40 Information and second code information identical to the first code information are input (ST102).

  The data transmission unit 12 of the second information terminal 50 transmits the input second code information to the server device 6 via the network 5 (ST103). When the server control unit 32 of the server device 6 receives the second code information, the server control unit 32 accesses the guardian database PDB constructed in the server storage unit 33 and stores the first code information that matches the second code information. The record PREC is searched (ST104). When the guardian record PREC in which the first code information is stored in the guardian database PDB (Yes in ST105), the server control unit 32 sets the file pointer of the record to be added to the guardian record PREC or the guest record GREC. Is written (ST106), and a new guest record GREC is generated and added to the guest database GDB (ST107).

  Hereinafter, a specific example of the registration process will be described with reference to FIG. Here, the second code information transmitted from the second information terminal 50 to the server device 6 matches the serial number 0 stored in the field 1 of the guardian record PREC_0, and the guest database GDB already has a guest record. Description will be made assuming that GREC_0_1 is registered and a guest record GREC_0_2 is newly added.

  Upon receiving the second code information, the server control unit 32 searches the guardian database PDB, and extracts the guardian record PREC_0 in which the second code information matches the serial number 0 (first code information) stored in Field1. Then, the value stored in Field5 is checked. In a situation where the guest 40 is not registered, NULL is stored in the Field 5 of the parent record PREC_0. However, since the file pointer PO1 is stored here, the server control unit 32 has already registered the guest 40. And the guest pointer GREC_0_1 is accessed with reference to the file pointer PO1.

  Next, the server control unit 32 checks the value stored in Field 5 of the guest record GREC_0_1. In this example, this value is NULL, and the server control unit 32 generates a new guest record GREC — 0_2, acquires the file pointer (PO2) of the guest record GREC — 0_2, and changes Field 5 of the guest record GREC — 0_1 from NULL to PO2. To do. Then, the serial number 0 stored in Field 1 of the parent record PREC_0, the unique identification information stored in Field 2, and the link information stored in Field 4 are copied to the corresponding Field of the guest record GREC_0_2, and further The contact information of the guest 40 transmitted from the second information terminal 50 is stored in Field 3 as contact information 0_2. This completes the registration process for the new guest 40.

  FIG. 10 is an explanatory diagram showing an overview of the processing of the search system S2 when the guest 40 becomes an active searcher in the second embodiment of the present invention. Hereinafter, the processing content of the search system S2 after the registration process of the guest 40 is completed will be described using FIG. 8 together with FIG. In the following description, the guests 40a and 40b install and start a dedicated application, and the guest record GRE_0_1 and the guest record GREC__2 are associated with the guests 40a and 40b, respectively, by the registration process described above. And Further, the description will be made on the assumption that the guest 40a is in the range of radio waves of the transmitter 2 carried by the protection target 1.

  When the guest 40a moves from the point C to the point D and reaches the reach of the radio wave transmitted by the transmitter 2, the second information terminal 50a receives the unique identification information transmitted by the transmitter 2, and the time / position And the unique identification information is transmitted to the server device 6. The server device 6 stores the received time / position and unique identification information as search history information in the server storage unit 33, searches the guardian database PDB, and stores the received unique identification information. PREC (here, the guardian record PREC_0) is extracted, and based on the contact information 0_0 stored in the guardian record PREC_0, the position information and the like to be protected are stored in the first information terminal 4 possessed by the guardian 3 Send.

  Further, the server device 6 refers to the guest record GREC_0_1 with reference to the file pointer PO1 stored in the field 5 of the guardian record PREC_0. Then, the contact information 0_1 stored in Field3 is extracted, and the protection target position information and the like are transmitted to the second information terminal 50a possessed by the guest 40a. Next, the server device 6 refers to the guest record GREC_0_2 with reference to the file point PO2 stored in the field 5 of the guest record GREC_0_1. Similarly, the contact information 0_2 is extracted, and the protection target position information and the like are transmitted to the second information terminal 50b possessed by the guest 40b.

  In the example described above, the second information terminal 50a carried by the guest 40a has been described as receiving the unique identification information transmitted by the transmitter 2. However, the guardian 3 carries the information terminal that receives the unique identification number. The first information terminal 4 may be the second information terminal 50b carried by the guest 40b, or the second information terminal 50 carried by a passive searcher. 3 and the guests 40a, 40b (active investigators) are transmitted the position information to be protected.

  Thus, in the second embodiment, the server device 6 is a server storage unit in which a database (guardian database PDB) in which the first code information specifying the transmitter 2 and the unique identification information are associated in advance is constructed. 33, the second information terminal 50 transmits the second code information input by the user of the second information terminal 50 and the contact information of the user of the second information terminal 50 to the server device 6, and the server device 6 stores the identification information unique to the server storage unit 33 and the contact information of the user of the second information terminal 50 in association with each other on the condition that the second code information and the first code information match (guest The guest record GREC stored in the database GDB), and the server device 6 receives the unique identification information and the first information terminal 4 (or second information) from the first information terminal 4 (or second information terminal 50). When the position information (time / position and unique identification information) is received, the second information terminal 50 is referred to by referring to the contact information of the user of the second information terminal 50 (or the first information terminal 4). The position information of the first information terminal 4 (or the second information terminal 50) is transmitted to (or the first information terminal 4).

  That is, by the registration process in the guest database GDB, the guest 40 who was originally a passive searcher is converted to an active searcher and can be actively involved in searching for the protection target 1.

  In addition, as described above, the time and position at which the protection target 1 is discovered are stored as search history information in the server storage unit 33, and the guest 40 that has completed the registration process operates the second information terminal 50. Thus, the search history information can be accessed as necessary, and the second information terminal 50 captures the history of the time and position at which the protection target 1 is found, and displays it overlaid with the map information.

  As described above, in the second embodiment, the time / position and unique identification information acquired by the second information terminal 50 possessed by the guest 40 are the server regardless of whether the searcher is a passive searcher or an active searcher. The search history information is stored in the server storage unit 33 of the device 6, and the guardian 3 and the active searcher can share the search history information and use it for searching the protection target 1.

  Now, in the “search mode” in which the guest 40 becomes an active searcher, the time / position and unique identification information are transmitted from the first information terminal 4 or the second information terminal 50 to the server device 6. The server device 6 always returns the position information subject to protection to the first information terminal 4 and the second information terminal 50. However, depending on the convenience of the guest 40, there may be a situation in which notification of position information or the like of the protection target 1 is not desired in a scene where the protection target 1 is searched. Therefore, in the second embodiment, in the “search mode”, when the guest 40 inputs display permission / inhibition to the second input unit 55, the second terminal control unit 56 follows the instruction of the guest 40 (user). Whether to display the position information acquired from the first information terminal 4 and the second information terminal 50 transmitted from the server device 6 (protection target position information or the like) is controlled. Of course, also in the second embodiment, the guardian 3 can set whether or not to display position information or the like on the first information terminal 4.

  As described above, the search systems S1 and S2 according to the present invention have been described in detail based on specific embodiments. However, these embodiments are merely examples, and the present invention is not limited to these embodiments. . For example, in the first embodiment, when the first terminal control unit 16 receives an interrupt signal from the short-range wireless communication unit 10, the latitude / longitude information acquired from the first position information acquisition unit 11 immediately before is received by the server device 6. However, the first terminal control unit 16 may estimate the latitude / longitude information based on the previous search history information. Further, the latitude / longitude information may be estimated by the server device 6.

  In the above-described embodiment, the search systems S1 and S2 according to the present invention have been described mainly assuming a pet as the protection target object 1 to be searched and watched over. It may be an elderly person or a child who is worried about getting lost. Further, in a theme park or the like, for example, a child who is worried about getting lost may have the transmitter 2 carried, and not only the guardian 3 It is also possible to install a dedicated application on the information terminal of the theme park employee and participate in the search for lost children as a passive searcher or an active searcher.

  In the search system according to the present invention, when the setting of the mode setting unit 14 is set to not search for the protection target 1, the search system is unique compared to the setting for searching for the protection target 1. The frequency of transmitting the identification information and the position information to the server device 6 is lowered, and the passive searcher is changed to the active searcher and actively involved in the search for the protection target 1 required. Since it is possible, it can be suitably applied to a monitoring system and a search system for pets and elderly people who may be jealous.
