The power detection unit 103 is connected to the power storage mechanism 12 and the sound controller 102 . The power detection unit 103 confirms the power supply state by detecting the voltage between the power storage mechanism 12 and the power output mechanism 21 . In this embodiment, the power storage mechanism 12 is a rechargeable battery, which is connected to the sounding mechanism 11 on the one hand to provide the power required by the sounding mechanism 11, and is connected to the power output mechanism 21 of the vehicle on the other hand. It is charged with the power extracted from the power output mechanism 21 . The power output mechanism 21 can be a storage battery or a storage battery of the vehicle 2 .

The sensing receiver 104 is connected to the sound controller 102 , and a microwave sensing device 14 and an air pressure sensing device 15 are connected to the sensing receiver 104 . The microwave sensing device 14 includes several microwave sensors, and the air pressure sensing device 15 includes several air pressure sensors, and these sensors are arranged anywhere on the vehicle. When a thief breaks the car window and enters the car to steal, several microwave sensors can emit microwaves and reflect them to the microwave sensing device 14, thereby sensing the intrusion of foreign objects in the car. Alternatively, the air pressure sensor senses the change in air pressure caused by the broken window, and sends it back to the air pressure sensing device 15 .

The following describes how the vehicle anti-theft device 100 enters the anti-theft mode. The driver presses the original car remote controller 24 to control the vehicle computer mechanism 20. After the vehicle computer mechanism 20 recognizes the chip identification code of the original vehicle controller 24, the central locking system 235 of the vehicle 2 is locked. The information deriving controller 101 obtains the locking/unlocking information of the central control locking system 235 through the controller local area network processing circuit 13, and then enters the anti-theft mode after confirming that the central control locking system 235 is locked, and controls the sounding mechanism 11 to make a light sound, so that The driver confirms to enter the anti-theft mode.

The information deriving controller 101 guides out the vehicle safety information 23 of the vehicle computer mechanism 20, and if there is an abnormal situation, the sounding mechanism 11 is controlled by the sounding controller 102 to make a sound, so as to deter thieves from stealing. At this time, if the thief wants to cut off the connection between the vehicle anti-theft device 100 and the power output mechanism 21 , the power storage mechanism 12 still supplies power to the sounding mechanism 11 , so the sounding mechanism 11 can continue to emit sound. Alternatively, the vehicle anti-theft device 100 controls the sound device 22 connected to the vehicle computer 20 to make a sound, which can also achieve a deterrent effect.

With the above-mentioned structure, the signal of the vehicle computer mechanism 20 is picked up from the on-vehicle diagnostic system connector, eliminating the need to install redundant anti-theft receivers and anti-theft remote controllers, and the anti-theft effect can be achieved only by the control of the original vehicle controller 24.
