Description

Automatic call system in case of vehicle theft

The present invention relates to an anti-theft device provided in a vehicle, and more particularly to an anti-theft device provided in a vehicle, which automatically opens the door of the vehicle by illegal means, invites intruder, rides a person or tilts the vehicle To an automatic calling system in case of a vehicle theft preventing the vehicle from being stolen.

Generally, a vehicle is equipped with an automatic alarm to prevent the vehicle from being stolen, and when there is a person illegally occupying the vehicle, an alarm sound is generated and the emergency light of the vehicle 1 is blinked, Theft of the vehicle is informed.

However, there has been a problem in that, when a vehicle occupant illegally occupies the vehicle temporarily, the operation of the automatic alarm of the vehicle is stolen by stealing the vehicle.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an electric power steering apparatus which is equipped with an open / close switch sensor for mechanically or electrically detecting movement of an opening / closing part of a vehicle door, An ultrasonic detecting sensor for detecting the confusion of a sound wave when the glass of the vehicle is broken or a person is moving in the room by putting an ultrasonic wave in the room, In order to tow a vehicle, an alarm is activated in response to a signal from a vibration detection sensor that detects the movement of the vehicle when the vehicle is tilted to generate an alarm sound. The emergency light flashing circuit is operated to blink the emergency light, A vehicle stolen by preventing a vehicle from being stolen by calling a predetermined telephone number through The present invention is directed to providing such a calling system.

1 is a schematic block diagram of an automatic paging system for a vehicle theft according to the present invention.

In order to achieve the above object, the present invention provides an electric vehicle comprising: an open / close switch sensor for mechanically or electrically detecting movement of an opening / closing part of a vehicle door or the like; An ultrasonic detecting sensor for detecting a confusion of a sound wave when the glass of the vehicle is broken or the person is moving in the room by putting an ultrasonic wave in the room, A vibration detecting sensor for detecting a movement of the vehicle when the vehicle is tilted; a logic circuit for generating a constant control signal when at least one of the sensors is input; An emergency light flicker circuit for blinking an emergency light, and a predetermined telephone designated by the owner of the vehicle And an automatic paging controller for generating an alarm of a vehicle stolen by calling a number.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, when the operation switch 310 of the automatic call controller 300 of the vehicle is pressed, a predetermined time elapses, and the opening / closing switch sensor 10 provided at a predetermined portion of the vehicle door, The movement of the opening / closing part or the movement of the locking mechanism is detected mechanically or electrically and transmitted to the logic circuit 100. When the door of the vehicle is opened by the current change detection sensor 20 connected to the interior lighting circuit of the vehicle, Detects a change in current due to the operation of an electric component such as an interior lamp and transmits the detection result to the logic circuit 100. The ultrasound detection sensor 30 provided at a predetermined portion of the dashboard of the vehicle detects the change in current, When the glass breaks or a person moves in the room, the ultrasonic wave is detected and transmitted to the logic circuit 100, and vibration detection When tilted to the vehicle in order to drive the standing or riding vehicle to a person in the vehicle 40, by detecting the movement of the vehicle it is transmitted to the logic circuit 100.

When at least one of the signals of the open / close switch sensor 10, the current change detection sensor 20, the ultrasonic detection sensor 30 and the vibration detection sensor 40 is input to the logic circuit 100, The emergency alarm flicker circuit 220 is activated to generate an alarm sound, and the emergency light flashes to alert the vehicle to the theft, generate a constant control signal, and transmit the control signal to the automatic call controller 300. The automatic call controller 300 generates a control signal corresponding to a predetermined telephone number and transmits the control signal to the automobile telephone 400. The automobile telephone 400 controls the automatic call controller 300 And calls a telephone number already set according to the signal to alarm the theft of the vehicle.

In particular, the automatic paging controller 300 is connected to the vehicle telephone 400 and includes an operation switch 310 for operating the automatic paging system, and an operation switch 310 for allowing the vehicle owner to input a telephone number And a key input unit 320 for inputting the key input. The operation switch 310 includes a delay circuit (not shown) for allowing a driver to close the door and operate after a predetermined time, a wireless receiver (not shown) for allowing the user to turn on or off the wireless device from the outside, The ten-key input unit 320 is composed of ten key panels of one-digit numbers and function keys for completing the input, so that it is possible to change a telephone number arbitrarily called according to the choice of the owner of the vehicle.

As described above, the automatic paging system according to the present invention detects the opening and closing of the door by the opening / closing switch sensor 10 while the automatic paging system is operating, and the operation of the electric device of the vehicle by the current change detection sensor 20 Detects the movement of a person in the vehicle by the ultrasonic detecting sensor 30, detects the motion of the vehicle by the vibration detecting sensor 40, and detects any one of the abnormal signals of the vehicle, The circuit 320 can be operated to notify the owner of the vehicle around the vehicle of the fact that the vehicle has been stolen. In addition, even if the owner of the vehicle enters the house, the predetermined phone number that has already been set is called, So that theft of the vehicle can be prevented.
