Description

The utility model relates to satellite positioning devices, in particular, to a hidden installation device on an object that informs the user about the location of the device and, accordingly, the object (object) in which it is located.

One of the key factors in reducing the risk of loss/theft of property or loss of a person is the availability of reliable and up-to-date information about the actual location of the controlled object, as well as the immediate informing of interested parties about the occurrence of an emergency situation of any type.

It is obvious that the most effective system will be the one that allows you to automatically and with high accuracy in real time to fix the location and movement of a controlled object, track its location in a given area at user-defined intervals, and automatically provide information to authorized persons about all events that violate the laid down restrictions (going beyond the permitted zone, time delays with arrival in a given area or with departure from a given area).

A device for monitoring the position of the machine is known, which is a mobile communicator and installed on a moving object, which compares the information received via GSM channels about the location of the device with predetermined information about the route and, in case of deviation from it, transmits an alarm message to the control point (patent US 6204772 B1 , published 03/20/2001).

From patent RU 147324 U1, published on November 10, 2014, a satellite positioning and object location device is known that uses a satellite navigation system that transmits information about the location of the device via cellular communication channels of GSM operators, which contains a GSM module equipped with 2-4 SIM cards or SIM-chips of various mobile operators with different areas of service provision.

Known devices work as follows. The device determines geographic coordinates using the built-in navigation unit (for example, GPS, GLONASS and others). Further, information about geographic coordinates and information from sensors is transmitted to the user via cellular communication channels (for example, GSM/GPRS/3G/4G): via SMS messages, or via mobile Internet. To do this, all devices of this type include a cellular communication unit.

The disadvantage of the known technical solutions is the dependence of positioning on the presence of a satellite signal, which leads to the impossibility of determining the location in the absence or insufficient quality of the satellite signal, as well as the impossibility of determining the accuracy in the horizontal plane more precisely than 2 meters, determining the height relative to sea level with even less accuracy. The reason for this may be the location of the device in buildings with metal-concrete partitions and floors, under objects and canopies that shield the satellite signal, weather conditions, local technical limitations and malfunctions of satellite navigation systems.

The task to be solved by the claimed utility model is to reduce the dependence of the possibility of determining the location (geopositioning) on the presence / absence and quality of the satellite signal, providing the possibility of determining the location in an alternative way using the built-in Bluetooth radio channel module.

The technical result is to increase the accuracy of determining the location of the object.

This technical result is achieved due to the fact that a device for hidden installation on an object for determining the location of an object using a satellite navigation system contains a processor unit, a satellite navigation unit and a cellular radio communication unit that transmits information about the location of the device via mobile communication channels. At the same time, the processor unit is connected to the satellite navigation unit and the cellular radio communication unit. According to the proposed utility model, the device additionally includes a Bluetooth module configured to scan and determine within its Bluetooth range a pair of the user's mobile device, the processor unit is connected to the Bluetooth module, the cellular radio unit is configured to receive commands from the user, and the processor is configured with the ability, after receiving a command from the user, to turn on the Bluetooth module for permanent connection with the user's mobile device via the Bluetooth channel to determine the location of the device by the Bluetooth signal strength level.

In one of the embodiments, the processor is configured with the help of a cellular radio communication unit to transmit to the server or the user's mobile device via mobile communication channels the number designations of the available base stations of cellular networks (Cell ID).

In another embodiment, the device contains a Wi-Fi module for scanning Wi-Fi MAC addresses, which determines the MAC addresses of Wi-Fi access points within its range, and the processor is configured to transmit this information to the server using the cellular radio unit. or a user's mobile device via mobile communication channels.

On FIG. 1 is a block diagram of a device in a single SIM embodiment.

On FIG. 2 shows a block diagram of the device in the embodiment with a Wi-Fi module and one SIM card.

On FIG. 3 is a block diagram of the device in the dual SIM embodiment.

On FIG. 4 shows a block diagram of the device in the embodiment with a Wi-Fi module and two SIM cards.

The device is equipped with a navigation unit (1), a processor unit (2), a sensor unit (3), a cellular radio unit (4) and a Bluetooth module (6), which determines, within its Bluetooth range, pairs of a mobile phone with software installed on it. The device also includes a battery backup.

In one of the embodiments, the device additionally includes a Wi-Fi MAC address scanning unit - Wi-Fi module (5), which determines the MAC addresses of Wi-Fi access points within its range.

The device is designed to determine the exact location of a protected object using GLONASS / GPS satellite systems, as well as determine the approximate location according to data from base stations of cellular networks and identifiers of surrounding Wi-Fi access points.

The device uses a satellite navigation system (systems) (for example, GPS, GLONASS and others) to determine its own location by means of a built-in navigation unit (1) and transmits information about the location and status of the device's sensors via cellular channels. For this, the device includes a cellular radio communication unit (4) (GSM/GPRS/3G/4G modem). Optionally, the device may transmit to the user's mobile device and/or to the server, using the cellular radio unit, the number designations of the available base stations of cellular networks (Cell ID) and/or identifiers of the surrounding Wi-Fi access points.

The coordinates of the protected object and recorded events are transmitted via GSM networks via the GPRS protocol to the monitoring server and / or via SMS messages to selected phone numbers. The device is equipped with an acceleration sensor (accelerometer) to control movement, shock and flip, as well as a Micro USB connector for configuring the device using a personal computer.

The device may contain one main (MULTI SIM) SIM card/chip (Multi Sim-Card/Multi SIM card) and an additional (reserve SIM) SIM card/chip, which is used as a backup. As the main one, it is supposed to use a SIM card/chip (Multi Sim-Card/Multi SIM card) that works with all telecom operators (example: https://m2mexpress.ru/). A backup SIM card/chip of any telecom operator is used in case of breakdown (failure) of the main SIM card/chip (Multi Sim-Card/Multi SIM card).

To improve positioning accuracy, the device is equipped with a Bluetooth BLE module to check the presence of the owner's mobile device near the device and find the exact location of the device in space.

The user, via GSM cellular communication channels: via SMS messages, or via the mobile Internet GPRS/3G/4G, sends a command to the device to turn on the Bluetooth module (6), to determine the exact location of the device and, accordingly, the tracking object. The device, upon receipt of such a command by the cellular radio unit, activates the Bluetooth module (6) through the processor, which allows to determine the location of the device with an accuracy of tens of centimeters. Additionally, the conditions that require the inclusion of the Bluetooth module (6) are determined by the internal logic of the processor unit (2), user-programmed settings and other operating conditions of the device.

The search for geographic coordinates is carried out using a mobile device with software installed on it. The determination of the exact location of the device in this way is based on the indicator of the level of the received signal, RSSI - the total power of the signal received by the receiver. Measured by the receiver on a logarithmic scale in dBm (dBm, decibel re 1 milliwatt). Since this value is a power, based on its level, we can assume the relative range in any receiver according to the principle “the stronger the signal, the closer the source”. In this application, Bluetooth is simply a specific radio receiver/radio transmitter communication protocol on a specific frequency band. The received data will correspond to the geographical coordinates of the device, within the error of the Bluetooth module (6). That is, the obtained coordinates will be the geographical coordinates of the device itself, or the object (object) in which (in the immediate vicinity of which) it is located with an accuracy of tens of centimeters.

For direction finding of the device, the active BLE scanning mode is used, in which the smartphone, having received a package from the device on one of the announcement channels (ADV_IND or ADV_SCAN_IND type), sends a request on the same channel. This is an empty SCAN_REQ command. It must be transmitted no later than T_IFS (Time Inter Frame Space), which is 150 µs. In order for the advertiser to hear this request, after each advertisement, it lingers on the channel for the time T_IFS. If the request is received, the device responds with a SCAN_RSP response. When requesting a SCAN_REQ, the device sends all additional information about itself in the SCAN_RSP frame.

The processor, using software to change the power level of the Bluetooth signal, calculates the distance to the user's mobile device. Information about the direction and proximity to the coordinates of the device location is transmitted to the user via Bluetooth and displayed on the screen of the user's mobile device (for example, a smartphone). Software for calculating the distance from the device may also be installed on the user's mobile device. To do this, all mobile devices of this type include a Bluetooth unit (Bluetooth modem). Moving, the user is looking for the maximum level of the emitted signal. When searching in a building, it becomes possible to determine the floor and apartment (office) in which the device is located. The software installed on the user's mobile device allows you to visually display a graph of changes in the strength of the radio signal from the device, which depends on the distance to it. Thus, the task of establishing the exact location of the device on the ground is greatly simplified, when exact satellite coordinates are not available, or when it is necessary to understand exactly where the device is located in the protected object, if this cannot be done visually.

The device in the embodiment with a Wi-Fi module (5) for scanning Wi-Fi MAC addresses determines geographic coordinates using the built-in satellite unit (1) (for example, GPS, GLONASS and others). In this embodiment, for example, in case of unsuccessful determination of satellite coordinates, the device activates the Wi-Fi module (5) and determines the MAC addresses of Wi-Fi access points within its range. Conditions that require alternate location determination are determined by the internal logic of the processor unit (2), user-defined settings, and other operating conditions of the device. Further, information about geographic coordinates, MAC addresses is transmitted to the user via GSM cellular channels: via SMS messages, or via mobile Internet GPRS/3G/4G. To do this, the device includes a cellular communication unit (4).

The search for geographic coordinates of received MAC addresses is carried out in the databases of matching MAC addresses and geographic coordinates of the location of WiFi access points. The databases provide Yandex/Google services collected by geolocation services for the MAC addresses of Wi-Fi access points (accuracy up to tens of meters).

Based on the logic that the Yandex/Google services database contains information only about stationary (fixed) Wi-Fi devices (access points) with unique MAC addresses, the geographic coordinates obtained from the database will correspond to the geographic coordinates of the device, within error equal to the range of the scanning unit. That is, the received coordinates will be the geographical coordinates of the device itself, or the object (object) in which (in the immediate vicinity of which) it is located.

Thus, the device can determine the approximate location of the protected object even in the absence of a signal from satellites, for example, in a garage, in an underground parking lot, in a container, or when the GLONASS / GPS signal is deliberately jammed by radio equipment.

Such relatively low accuracy in the conditions of the city or the private sector of development does not give grounds to understand exactly where to look for stolen or lost property. Even in the presence of navigation coordinates, their accuracy does not allow us to confidently determine in which garage the stolen car is located. After all, the accuracy of determination by satellites in such a place is about 10 meters, at best. For example, with an average garage width of 3 meters, at least 3 garages fall into the position zone. If small-sized property equipped with a search device is stolen/lost, then even the presence of navigation coordinates will not give an understanding, for example, in which apartment and on which floor it is located.

The user, via GSM cellular communication channels: via SMS messages, or via the mobile Internet GPRS/3G/4G, sends a command to the device to turn on the Bluetooth module (6), to determine the exact location of the device and, accordingly, the tracking object. The device, upon receipt of such a command by the cellular radio unit, activates the Bluetooth module (6) through the processor, which allows to determine the location of the device with an accuracy of tens of centimeters. The processor, using software to change the power level of the Bluetooth signal, calculates the distance to the user's mobile device and transmits information about the direction and proximity to the coordinates of the device's location to the user via the Bluetooth channel. The software for calculating the distance from the device can also be installed on the user's mobile device (smartphone). Moving, the user is looking for the maximum level of the emitted signal. When searching in a building, it becomes possible to determine the floor and apartment (office) in which the device is located. The software installed on the user's mobile device allows you to visually display a graph of changes in the strength of the radio signal from the device, which depends on the distance to it. Thus, the task of establishing the exact location of the device on the ground is greatly simplified, when exact satellite coordinates are not available, or when it is necessary to understand exactly where the device is located in the protected object, if this cannot be done visually.

Thus, the technical result is achieved, which consists in increasing the accuracy of determining the location of the object. An increase in the area of operation of the device is also achieved, due to the "addition" of the Bluetooth coverage area and the zone of a stable signal of satellite navigation systems, an increase in the reliability of the device in areas of local failures of satellite navigation systems.

The device may contain a built-in non-volatile memory connected to the processor, which allows you to save at least 15000 unsent GPRS packets, in case there was no connection with the monitoring server, and send them as soon as the connection with it is restored.

In addition to coordinates, speed, direction of movement and the fact of crossing the boundary of the configured circular geofence, all device settings and the current state can be transmitted in messages received from the device. As service information, messages can include data on the date and time of determining the coordinates, battery life determined by the processor using software, temperature inside the device, set operating modes, the number of navigation satellites found, the GSM network signal level, the number of sent SMS messages etc.

The sensor block (3) includes a digital accelerometer, a photo sensor for dismantling and opening the housing, a digital thermometer.

The digital accelerometer registers movements and impacts on the protected object. This allows you to set up notifications about the events of the start of movement after parking, the beginning of parking, long-term movement for more than 8 hours, long idle time for more than 14 days, significant accidents, turns of more than 90 degrees in any plane.

The presence of a thermometer allows you to receive information about the ambient temperature and set up notifications about the temperature going beyond the set values.

The case dismantling and opening photosensor detects the device case being dismantled/opened, and then the device transmits information about this event to the owner's server/phone.

The software allows the processor to accurately estimate the amount of energy consumed by the device's built-in batteries in mAh.

The device can operate in two main modes: continuous online and interval sleep. In continuous online mode, the device is constantly in touch and is ready to accept a command from the owner at any time. The online mode requires a lot of battery power consumption, so the maximum operating time without recharging the built-in battery in this mode is up to 20 days. If the exact GLONASS / GPS coordinates are constantly determined (tracking mode), then the battery life is reduced to 4 days. In the interval sleep mode, almost all device modules are in the off state, so the device receives and executes commands only at short moments of communication, which occurs according to the time programmed in its main and additional alarms. Thanks to micro-consumption in sleep mode, the device can work autonomously from built-in batteries for up to 6 years if it contacts once a day.

The autonomy and compact dimensions of the device allow the owner to install it in a place that is difficult to find. Since the device is usually in sleep mode most of the time, it is extremely difficult to determine its presence with air scanners and GSM signal detectors. If intruders use a jamming or suppression system for GSM frequencies, then the long battery life of the device will allow you to wait for the suppression means to turn off and get in touch with the owner.

The device can be used for the following purposes:

Theft protection and stolen vehicle detection.

Monitoring the movement of valuable goods and searching for them in case of loss.

Monitoring of personal, official and special vehicles.

Determination of the location of stolen motorcycles, ATVs, scooters, bicycles and other movable equipment.

Control of needy guardianship of children, elderly and sick people.

Controlling the location of pets.
