Automobile fingerprint burglar alarm, control method and control circuit

Abstract

The invention discloses an automobile fingerprint burglar alarm, a control method and a control circuit; in the method, a remote controller senses the existence of a finger and sends out a finger existence signal; the finger existence signal triggers and outputs power supply enabling signals of a fingerprint acquisition module and an image processing module and starts the fingerprint acquisition module; and a starting controller starts a car or cuts off an oil way of a car engine and gives an alarm according to the fingerprint verification result. In the method, the fingerprint verification result is transmitted to a wireless receiving module in the starting controller by a wireless transmitting module. In the invention, the existence of the finger is sensed first, the fingerprint acquisition module can be started to work when only sensing the existence of the finger, and when the existence of the finger is not sensed, the fingerprint acquisition module does not work; and as the fingerprint acquisition module is a part which consumes most power in the whole system, and the power consumption of the system can be greatly reduced, therefore, the aim of lowering power consumption is realized. Further, the wireless fingerprint remote control function with low power consumption is realized on the basis.

Description

technical field [0001] The invention relates to an automobile anti-theft device, in particular to an automobile fingerprint anti-theft device, a control method and a control circuit. Background technique [0002] With the continuous improvement of people's living standards, cars have gradually spread to the families of ordinary people. But, along with the increase of automobile quantity, the phenomenon of losing a car is also more and more, especially some high-end cars. In order to prevent theft, many manufacturers have introduced various car anti-theft systems, mainly including mechanical anti-theft devices and electronic anti-theft devices. The mechanical anti-theft device is the simplest and cheapest type of anti-theft device on the market, and its principle is also very Simple, just lock the steering wheel and control pedals or gear lever. The advantage of this kind of anti-theft device is that it is cheap and easy to install, but the disadvantage is that the anti-the...
