It can also be set to operate.

The communication unit 170 receives a photographing control signal transmitted through the second mobile communication terminal 300 at a remote location and transmits it to the controller 110, or an image captured by the camera unit 120 or the storage unit. It serves to transmit the image stored in the 150 as a wireless signal. Here, the video signal transmitted from the communication unit 170 in the form of a radio signal is transmitted to the second mobile communication terminal 300 via the base stations 210 and 230 and displayed to the user under the control of the mobile communication switching center 220. .

3 is a block diagram illustrating an internal configuration of the second mobile communication terminal according to the present invention. The second mobile communication terminal 300 transmits a shooting control signal to the first mobile communication terminal 100 to control a surveillance camera operation or to receive image data transmitted from the first mobile communication terminal 300. It is a device for. However, the present invention is not limited thereto, and the second mobile communication terminal 300 may be used as long as it is a device capable of transmitting and receiving data with the first mobile communication terminal 100, and the first mobile communication terminal 100. ) Itself may be used as it is.

The second mobile communication terminal 300 includes a communication unit 310, a control unit 320, a codec 325, a display unit 330, a storage unit 340, and an input unit 350.

The communication unit 310 receives an image signal transmitted from the first mobile communication terminal 100 or transmits a shooting control signal input by a user through the input unit 350 to the first mobile communication terminal 100. It plays a role.

The video signal received through the communication unit 310 is decoded by the codec 325 under the control of the control unit 320 and displayed on the display unit 330, so that the user of the camera unit of the first mobile communication terminal 100 In operation 120, the captured image may be checked. In addition, an image signal decoded by the codec 325 may be stored in the storage unit 340 according to a user's selection.

The input unit 350 is a place where a remote user inputs a command for controlling the operation of the first mobile communication terminal 100. For example, a key for controlling a pan, tilt, zoom function, etc. of the camera and the like is provided. And a key for selecting a photographing control signal for starting photographing of the first mobile communication terminal 100 in the manual mode. The control command input by the user through the input unit 350 is transmitted through the communication unit 310 via the control unit 320.

Through the second mobile communication terminal 300 as described above, a user checks an image captured by the camera unit 120 of the first mobile communication terminal 100 at a remote location, or a key through the input unit 350. Operation can be controlled to start recording, pan / tilt / zoom, etc. of the camera unit 120.

Hereinafter, an operation of a vehicular surveillance camera device using a mobile communication terminal according to the present invention will be described with reference to FIGS. 4 and 5.

4 is a flowchart illustrating the operation of the surveillance camera device when the mobile communication terminal according to the present invention operates in the manual mode.

Here, the manual mode refers to a mode in which the camera unit 120 operates when the camera unit 120 does not automatically operate by the sensor unit 200 and receives a predetermined shooting control signal from a user. Say.

First, the user sets the manual mode through the input unit 160 of the first mobile communication terminal 100 (step 400). When the control unit 110 is set to the manual mode, the controller 110 controls the entire apparatus to switch to the standby mode state (step 405). Here, the standby mode is a state in which the starting current of the control unit 110 flows only a few ㎂ to several tens of watts while the power of the display unit 140 is turned off so that the power consumption of the display unit 140 is performed to save power. Say. When the photographing control signal is received through the communication unit 170 in the standby mode, the control unit 110 allows a normal operation current to flow for operating the surveillance camera (step 410).

As described above, when the photographing control signal is received in the standby mode, it is determined whether the control signal is a control signal from a user who has permission to use (step 415). For example, in the case of a mobile phone, the controller 110 may check the telephone number of the user who transmitted the control signal to determine whether the control signal is from a user who has permission to use the mobile phone.

If the photographing control signal is a control signal from a user who has a right to use, the controller 110 operates the camera unit 120 to start photographing (step 420).

The image captured by the camera unit 120 is compressed by the codec 115 and transmitted to the user's mobile communication terminal through the communication unit 170 (step 425). The user of the second mobile communication terminal 300 receiving the video signal transmitted through the above process can view the image captured by the camera unit 120 of the first mobile communication terminal 100, Surveillance is possible.

The manual mode may be used regardless of whether the vehicle is equipped with a sensor for detecting an impact.

5 is a flowchart illustrating the operation of the surveillance camera device when the mobile communication terminal according to the present invention operates in the automatic mode.

In the automatic mode, when it is determined that a predetermined shock is applied to the vehicle by the sensor unit 200, the control unit 110 that detects a signal from the sensor unit 200 automatically controls the camera unit 120. To start shooting.

First, the user sets the automatic mode through the input unit 160 of the first mobile communication terminal 100 (step 500). When the control unit 110 is set to the automatic mode, the control unit 110 controls the entire apparatus to switch to the standby mode state (step 505). Here, the standby mode is a state in which the operation is performed with a minimum current consumption as in the manual mode, or by the shock in the sensor unit 200 in a state in which the main power of the first mobile communication terminal 100 is turned off. When a signal is detected, the camera is operated by turning on the main power by the operation of a predetermined switch.

As described above, in the standby mode state, the controller 110 determines whether a signal due to shock is detected through the sensor unit 200 (step 510), and the signal due to impact from the sensor unit 200 is detected. If so, the control unit 110 starts the shooting by operating the camera unit 120 (step 515).

The image captured by the camera unit 120 is compressed by the codec 115 and transmitted to the mobile communication terminal of the user through the communication unit 170, so that the user is installed in the vehicle even at a remote location. The image captured by the camera unit 120 of 100 may be checked.

The automatic mode is operable by connecting the surveillance camera device 100 using the mobile communication terminal according to the present invention to a vehicle equipped with at least the sensor unit 200.

As such, it will be understood by those skilled in the art that the present invention may be implemented in a modified form without departing from the essential features of the present invention. Therefore, the disclosed embodiments should be considered in descriptive sense only and not for purposes of limitation. The scope of the present invention is shown in the claims rather than the foregoing description, and all differences within the scope will be construed as being included in the present invention.

 According to the present invention as described above, it is possible to reduce the cost required for a vehicle surveillance camera device by using a mobile communication terminal having a camera that is widely spread.

In addition, according to the present invention, the user having a mobile communication terminal can monitor the situation around the vehicle from a remote location, and can inform the vehicle owner of accidents such as vehicle damage and theft, thereby preventing economic loss of the vehicle owner. Can be.
