Novel automobile anti-theft device

Abstract

The invention discloses a novel automobile anti-theft device, which aims to provide a novel automobile anti-theft device with less possibility of being stolen for a vehicle in case of decoding the password and losing the key. The novel vehicle anti-theft device comprises a singlechip (1), a speech chip (2), a filter circuit (3), a wireless receiver (4), a voltage stabilizing circuit (5), a power amplifying circuit (6), a multifunctional output circuit (7) and a defence starting-releasing key and circuit (8). When the defence starting-releasing key and circuit (8) is started, the vehicle cannot work normally by any behavior in attempt to use the vehicle illegally or in violation of the operating procedure of the vehicle; at the same time, the multifunctional output circuit (7) can start a built-in audio-video device hidden in the vehicle to record the image and the behavior of the operator. The novel vehicle anti-theft device can be widely used for various vehicles.

Description

technical field [0001] The invention relates to an automobile anti-theft device. Background technique [0002] There are more and more cars, more and more high-end cars, more and more car theft cases, and more and more sophisticated methods of committing crimes. Therefore, the industry of manufacturing car anti-theft devices has also been applied. The common car on the market There are many kinds of anti-theft devices: satellite positioning anti-theft device, which can identify where the stolen vehicle is; one anti-theft device can call the owner or the police (110) with intelligent functions when the vehicle is stolen; The fingerprint recognition function can cut off the oil and power of the vehicle in time when the vehicle is stolen. [0003] The above-mentioned car anti-theft devices are usually controlled by radio signals to achieve a comfortable anti-theft effect, but the technology of the car anti-theft decoders on the market is also very advanced, which can collect a...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned car anti-theft devices are usually controlled by radio signals to achieve a comfortable anti-theft effect, but the technology of the car anti-theft decoders on the market is also very advanced, which can collect and store hundreds or thousands of signals of wireless control anti-theft devices And the password, the anti-theft function of the anti-theft device can be released in a short time, so that the anti-theft device cannot play the role of anti-theft and alarm, and realize the purpose of quickly stealing the car

[0004] To sum up, the car anti-theft devices in the prior art have the disadvantages that the password may be decoded, the key may be stolen, and the vehicle may be stolen.
