[Technical field to which the invention belongs]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kind of two-way remote control anti-theft device for an automobile or a motorcycle, and more particularly to an anti-theft device capable of transmitting and receiving in two directions and displaying a detection state by a remote controller.

[0002]

[Prior art]

 Automobiles have become an indispensable transportation tool for modern people, but vehicle theft rates are also rising. For this reason, most private cars are equipped with anti-theft devices to prevent theft. A well-known electronic anti-theft device usually has one remote controller, and when the car owner leaves the car, the remote controller activates the anti-theft device inside the car to configure the anti-theft state. When a vehicle is subjected to vibration or intrusion, it activates an alarm and a lamp to generate a threatening effect and attract the attention of the vehicle owner or others. However, in a situation where there is insufficient parking, the vehicle may be far away from the owner's whereabouts, which may result in the vehicle owner not being aware of it even if it is stolen or moved. Electronic anti-theft devices have not been able to achieve the ideal anti-theft effect.

[0003]

[Problems to be solved by the device]

 The present invention is to provide a kind of two-way remote control anti-theft device for automobile, which comprises one anti-theft device body and one remote control device, the anti-theft device body and the remote control device. High-frequency reception, emission and encoding, decoding, and warning circuits are provided in each of them, and by setting the remote controller, the anti-theft device body proceeds with the door opening / closing, ramp, and anti-theft control processes, and In the anti-theft function state, when the detection member connected to the anti-theft device body detects a signal such as vibration or intrusion, the anti-theft device body activates the built-in alarm and the vehicle lamp. A signal is sent to the distant controller, the high frequency circuit of the distant controller receives and decodes, and one buzzer is driven to generate a warning sound. Directional remote control, It shall be able to improve the disadvantage that could not or shown.

[0004]

[Means for Solving the Problems]

 The invention of claim 1 comprises one anti-theft device main body and one remote controller, and at least a high-frequency emission and reception circuit and an encoding and decoding circuit are provided in each of the anti-theft device main body and the remote controller. A two-way remote control anti-theft device that advances the control process of opening and closing doors, lamps, and anti-theft devices on the body of the anti-theft device by setting the remote control device. When the anti-theft function is set by the detection member provided on the main unit, it detects a vibration or intrusion signal and sends it to the encode and decode circuits of the anti-theft device, which is emitted from the high-frequency emission circuit of the anti-theft device. Then, after the high-frequency receiving circuit of the remote controller receives the signal, it sends it to the encode and decode circuit of the remote controller to output one voltage, and one buzzer sounds an alarm. By generating, and performs bidirectional distant place control, and a bidirectional distant control antitheft device for motor vehicles or motorcycles.

[0005]

[Embodiment of the invention]

 Please refer to FIG. 1 and FIGS. The present invention comprises one portable remote controller 1 and one anti-theft device body 2 installed in the vehicle. Among them, the distant controller 1 is provided with an encoding and decoding circuit 11, and after setting a personal identification number, the push button switches 111 and 112 are turned on, so that the trigger signal is stolen from one high frequency emission circuit 12. When the high frequency receiving circuit 21 of the anti-theft device body 2 receives the signal, the signal is amplified by the amplifying circuit 22 and then sent to one encoding and decoding circuit 23 to decode the code, and the secret code is sent. If it is correct, the anti-theft device body 2 proceeds with control processes such as opening and closing the door, lamps and anti-theft. One detecting member 231 is connected to the encode / decode circuit 23. When the detecting member 231 detects a signal of vibration or intrusion of a person in the anti-theft setting state, the encode / decode circuit 23 detects the signal. To the remote controller 1 from the high-frequency emission circuit 24, and at the same time, an alarm sound is generated in the alarm device 25.

The signal emitted by the anti-theft device body 2 is received by the high frequency receiving circuit 13 of the remote controller 1, amplified by the amplifying circuit 14, and sent to the encoding / decoding circuit 11, where the secret code After comparison, one buzzer 15 is triggered to generate a warning sound, thereby prompting the vehicle owner to take appropriate action. As a matter of course, the working voltage required by the electric circuits of the remote controller 1 and the anti-theft device main body 2 is a stable voltage obtained by filtering the voltage in advance with one pressure stabilizing circuit 10, 20 and filtering. To be done. Further, if the buzzer 15 and the alarm device 25 are connected to an indicator lamp or a vehicle headlight, a warning effect by light and sound can be provided.

[0007]

[Effect of the invention]

 The present invention provides an alarm device with a built-in anti-theft device when the detection member connected to the anti-theft device detects a signal such as vibration or intrusion when the anti-theft device has the anti-theft function. In addition to activating the vehicle's lamp, the signal is sent to the distant controller, the high frequency circuit of the distant controller is received and decoded, and then one buzzer is driven to generate a warning sound. Therefore, it is possible to ameliorate the drawback that the known antitheft device can only perform unidirectional remote control and display.
