The security terminal 120 includes an application and determines whether the external physical quantity received from the sensing unit 110 exceeds a predetermined reference value. Also, the security terminal 120 transmits a free Internet telephone call, a text message, and / or a warning sound to the user terminal 130 to be performed when the external physical quantity exceeds the reference value. The security terminal 120 includes a Bluetooth unit 121 and a communication unit 122 capable of performing Wi-Fi, 3G, and 4G communication. The security terminal 120 further includes a speaker unit 123. Basically, the security terminal 120 may be a smart phone capable of Wi-Fi or Internet communication. More specifically, the secure terminal 120 may be a closed smartphone that is collected through a resource center or the like, but the invention is not limited thereby. Furthermore, the speaker unit 123 described above may be installed together with the sensing unit 110 according to circumstances.

The user terminal 130 also includes an application and receives a free internet telephone and / or text message from the security terminal 120 and transmits a response signal thereto. To this end, the user terminal 130 also includes a Bluetooth unit 131 and a communication unit 132 capable of performing Wi-Fi, 3G, and 4G communication. That is, the user terminal 130 may also be a conventional smart phone, but the present invention is not limited thereto.

When the security terminal 120 and the user terminal 130 are located in the same place (for example, a home), they can be connected to each other via Bluetooth or Wi-Fi. Also, the security terminal 120 and the user terminal 130 The wireless terminal 120 and the user terminal 130 may be connected to a Wi-Fi router 141 installed in a home, a common wired / wireless communication network 141, And can be connected to each other, as needed,

Furthermore, the security terminal 120 may communicate with a person outside the door, via the user terminal 130 and the security terminal 120, by transmitting a sound from the door to the user terminal 130.

Of course, in some cases, the user may report an emergency to the police directly via the user terminal 130. [

Furthermore, the security terminal 120 may output a predetermined warning sound through the speaker unit 123 when the user terminal 130 and the free internet telephone can not be connected as described above. The alarm sound may be outputted through the speaker unit 123 by controlling the security terminal 120 by the user terminal 130.

Referring to FIG. 3, an example of the sensing unit 110 and the security terminal 120 in the home security system 100 according to an embodiment of the present invention is shown.

As shown in FIG. 3, the sensing unit 110 for sensing an external physical quantity outside the door 149 may be installed directly on the door 149 separately from the security terminal 120. That is, the sensing unit 110 is installed directly on the door 149 and includes a microphone 111 for sensing the sound of a doorbell, a noise outside the door, a camera 112 for sensing an object outside the door, And a gyro sensor or an acceleration sensor for sensing the state. Of course, the microphone unit 111, the camera unit 112, the gyro sensor, and / or the acceleration sensor may be connected to the security terminal 120 in a Bluetooth or Wi-Fi manner.

Thus, according to the present invention, various situations (for example, a doorbell sound, a noise, an object movement, a door movement and a door open state) outside the door 149 are transmitted to the security terminal 120 through the sensing unit 110 And the security terminal 120 transmits the situation to the user terminal 130, so that the user can positively cope with the internal and external situations of the house.

Referring to FIG. 4, a block diagram of a security terminal 120 in a home security system 100 according to an exemplary embodiment of the present invention is shown.

As shown in FIG. 4, the security terminal 120 of the home security system 100 according to the present invention may be a conventional smartphone or a closed smartphone. In this case, the sensing unit 110 may be formed integrally with the security terminal 120, but the present invention is not limited thereto. As shown in FIG. 3, the sensing unit 110 may be formed separately from the security terminal 120 . Furthermore, the speaker unit 123 may be integrally formed with the sensing unit 110, or may be formed in the security terminal 120. [ Here, it is assumed that the security terminal 120 is integrally formed with the sensing unit 110.

The security terminal 120 includes a sensing unit 110 including a microphone unit 111, a camera unit 112 and an acceleration sensor 113, a Bluetooth unit 121 wirelessly connected to the user terminal 130, An input unit 124 for setting an application or inputting a setting value, an application 124, a sound recording and / or a sound recording unit 122, A display unit 126 for displaying various applications and control statuses, a warning sound generating unit 127a for generating a warning sound, a telephone transmission / reception unit for making a free internet call to the user terminal 130, A message transmission unit 127c for transmitting a message to the user terminal 130 and a control unit for receiving an electric signal for an external physical quantity from the sensing unit 110 or performing a predetermined control operation And a (128).

As described above, the microphone unit 111 senses a buzzer sound or noise outside the door, and transmits the sensed noise to the controller 128. The camera unit 112 senses the movement of the object outside the door, and transmits the sensed object motion to the control unit 128. In addition, the acceleration sensor 113 (or the gyro sensor) senses the door swing and / or the door open state and transmits the sensed state to the control unit 128. Of course, the security terminal 120 may be installed directly in the door 149 for this purpose. However, when the sensing unit 110 is installed separately from the security terminal 120 as described above, only the sensing unit 110 may be installed at the door.

Meanwhile, the control unit 128 determines whether the various physical quantities sensed through the sensing unit 110 exceed a predetermined reference value. For example, if the buzzer sounds, the external noise exceeds the reference decibel, an object is detected outside the door, or the door is forcibly shaken or is about to be opened, And transmits a text message to the user terminal 130 via the message transmitting unit 127c and the communication unit 132 via the Internet 127b and / Furthermore, the control unit 128 may transmit the real-time image captured by the camera unit 112 to the user terminal 130 through the communication unit 122. Also, the control unit 128 may cause the memory unit 125 to store the real-time moving image photographed by the camera unit 112.

Therefore, the user can talk with the security terminal 120 through the user terminal 130, for example, by transmitting the voice to the security terminal 120, the security terminal 120 can be communicated through the speaker unit 123 Allow user voice to be delivered out the door. For example, a user may be able to communicate with a person outside the door through the user terminal 130 and the security terminal 120, as if the user were at home.

In addition, the user may cause the security terminal 120 to output a warning sound through the speaker unit 123 by a predetermined operation. The security terminal 120 outputs a warning sound through the speaker unit 123 itself and / or transmits the alert signal to the telephone transmitting / receiving unit 127b and the communication unit 122 Or may automatically transmit a home invasion notification message to the police station through the message transmitting unit 127c and the communication unit 122. [

It goes without saying that, in use, the user can directly report a house invasion to the police station through the user terminal 130. [

Here, the warning sound generating unit 127a, the telephone transmitting / receiving unit 127b, and the message transmitting unit 127c may be implemented by software or hardware, and the present invention is not limited thereto.

Referring to FIG. 5, an operation flowchart of a home security system 100 according to an embodiment of the present invention is shown. Referring to FIG. 6, a home security system 100 according to an exemplary embodiment of the present invention, A data flow diagram between the terminal 110, the secure terminal 120, and the user terminal 130 is shown.

5 and 6, the operation sequence of the home security system 100 according to the present invention includes a step S1 of registering the user terminal 130 in the security terminal 120, a step S1 of registering the security terminal 120, (S2) determining whether a distance between the user terminal (130) and the user terminal (130) is out of a reference distance, determining whether an external (out door) physical quantity exceeds a reference value (S3) A step S5 of determining whether a wireless connection is successful between the security terminal 120 and the user terminal 130, a step of receiving and outputting a voice signal if the wireless connection is successful S6) and outputting an alarm sound when the wireless connection fails (S7). Hereinafter, the operation of the present invention will be described by limiting the subject of control to the security terminal 120. [

In step S1 of registering the user terminal 130 in the secure terminal 120, for example, each user terminal 130 of the family member is registered in the security terminal 120 provided in the home. That is, the security terminal 120 and each of the user terminals 130 are communicably connected using a Bluetooth communication method or a Wi-Fi communication method. Here, in order to use the Wi-Fi communication system, it is natural that a Wi-Fi router 141 connected to the Internet wired / wireless communication network 142 is installed in the home.

In this registration process, the security terminal 120 obtains a unique ID or telephone number for each user terminal 130 so that an Internet dial-up and / or message transmission to each user terminal 130 is possible. Of course, a separate application may be installed in the security terminal 120 and the user terminal 130 for this purpose.

In step S2, the security terminal 120 determines whether the distance between the security terminal 120 and the user terminal 130 is out of the reference distance. In this case, the security terminal 120 transmits at least one user It is determined whether or not the terminal 130 is present.

That is, if the security terminal 120 can communicate with at least one user terminal 130 by a Bluetooth communication method or a Wi-Fi communication method, the distance between the security terminal 120 and the user terminal 130 is within a reference distance . If the security terminal 120 can not communicate with all the user terminals 130 by the Bluetooth communication method or the Wi-Fi communication method, the security terminal 120 determines that the distance between the security terminal 120 and the user terminal 130 is out of the reference distance .

If the security terminal 120 and the at least one user terminal 130 are within the reference distance, the security terminal 120 does not perform the security operation described below, while the security terminal 120 and all of the user terminals 130 130 is out of the reference distance, the security terminal 120 performs the security operation described below (i.e., starting from step S3).

However, the present invention is not limited to this method, and it is possible to perform a security operation manually regardless of the reference distance.

In step S3 of determining whether the external physical quantity exceeds the reference value, the security terminal 120 uses the sensing unit 110 separately installed or the sensing unit 110 itself, Value is exceeded. That is, the security terminal 120 controls the sensing unit 110 so that the sound volume of the doorbell, the noise outside the door, the movement of the object, the noise inside the door, the movement of the object, the motion of the door, and / or the door opening exceeds the predetermined reference value Or not. Here, the buzzer sound and noise are acquired by the microphone unit 111 of the sensing unit 110, the object motion is acquired for the camera unit 112, and the door shake and / or door opening are detected by the gyro sensor or the acceleration sensor 113). Furthermore, the noise or object movement obtained by the microphone unit 111 and the camera unit 112 may be recorded and stored by the security terminal 120. [

If the external physical quantity does not exceed the reference value, the security terminal 120 returns to step S2. If the external physical quantity exceeds the reference value, the security terminal 120 performs step S4.

In step S4, when the external physical quantity exceeds the reference value, the security terminal 120 transmits a call to the user terminal 130 via the free Internet telephone system And makes a call to the user terminal 130 or makes a notification message. For example, the security terminal 120 transmits a notification message to the user terminal 130 by making a call to the user terminal 130 using the boystalk function of the KakaoTalk or using the 1: 1 chat function. Of course, it is a matter of course that an application having such a function is installed in advance in the security terminal 120, and it is a matter of course that a separate application for automatically making a call or sending a text message is installed in advance. In addition, although the cacao talk is described herein as an example, the present invention is not limited thereto, and other applications can be used.

Furthermore, the security terminal 120 sequentially transmits the free Internet telephone or the notification message to the predetermined user terminal 130. For example, if a response signal is not received from the user terminal 130 once within a predetermined time after transmitting a call or a notification message to the user terminal 130 registered at the first time, (130). In this order, the security terminal 120 circulates and transmits the telephone and / or notification message until at least one user terminal 130 responds.

The security terminal 120 and at least one user terminal 130 are communicably connected as described above in the step S5 of determining whether the wireless connection between the security terminal 120 and the user terminal 130 has succeeded Or not. Step S6 is performed if the connection is successful, and step S7 is performed if the connection is unsuccessful.

That is, when the wireless connection is successful, the security terminal 120 outputs the voice of the user received from the user terminal 130 using the speaker unit 123 in the voice reception and output step S6. For example, you can talk to someone outside the door. In other words, the user can hear the sound of a person outside the door through the microphone unit 111 of the sensing unit 110 of the security terminal 120 and the speaker unit 123 of the security terminal 120 Or may be installed together in the sensing section] to try to communicate with someone outside the door and pretend to be in the house. Further, by transmitting a predetermined command to the security terminal 120 through the user terminal 130, the security terminal 120 may output a warning sound through the speaker unit 123. [ Of course, the user can immediately inform the police about this situation.

In the step S7 of outputting the alarm sound when the wireless connection fails, the security terminal 120 can not communicate with all of the user terminals 130. At this time, a predetermined alarm sound is output to the speaker 123 Or transmit the current emergency situation to a predetermined police station, police box, or security company in real time. Of course, it is a matter of course that the security terminal 120 stores a telephone number of a police station, a police box or a security company in advance.

In this way, for example, the present invention sets a closed smartphone whose contract is canceled with a communication company to the security terminal 120, registers the user terminal 130 in the security terminal 120 in advance, It is determined that the user is in the home and the security terminal 120 is not operated when the user terminal 120 and the user terminal 130 are connected by Bluetooth or Wi-Fi, 130 is not connected to, for example, Bluetooth or Wi-Fi, it is determined that the user is outside the home and the security terminal 120 is operated.

That is, the security terminal 120 senses outside doorbell noise, outside door or noise of the door using the microphone unit 111, senses the object movement outside the door or the door using the camera unit 112, Or the acceleration sensor 113. When the sensed physical quantity exceeds the preset reference value, the user terminal 130 is connected to the user terminal 130 by, for example, a free internet telephone system Or a text message. For example, when the user terminal 130 transmits a response signal (e.g., a voice signal), the security terminal 120 outputs the response signal through the speaker unit.

In other words, the security terminal 120 is connected to the user terminal 130 through a free internet telephone when an external physical quantity (sound, image, door shake and / or door open) exceeds a reference value, The user can cope with the external situation through the security terminal 120 as if the user is at home.

Accordingly, the present invention not only enables the home security system 100 to be implemented at a low cost, but also enables efficient home security.

As described above, the present invention is not limited to the above-described embodiments, but can be applied to a home security system according to the present invention. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
