Automobile anti-theft control method based on key detection and fingerprint identification

Abstract

The invention discloses an automobile anti-theft control method based on key detection and fingerprint identification. An automobile anti-theft system is designed by adopting an enhanced low-power-consumption single-chip microcomputer, a fingerprint identification technology and a wireless communication GSM (Global System for Mobile Communications) technology. A circuit, an oil path and the like of an automobile are controlled through fingerprint identification by using the uniqueness of the biological characteristics of human body fingerprint, so that the aim of preventing theft is fulfilled. An anti-decoding characteristic can be realized by using the non-repeatability and complexity of a living fingerprint, so that the problems of over-the-air code interception, illegal acquisition of an electronic key for illegal driving, and the like in the conventional wireless remote control way are solved. A human defense function is added in the GSM technology, so that remote alarm is available through a wireless network. Through the design of the method, the defects of a single anti-theft circuit are overcome effectively, and the safety of the automobile is ensured.

Description

technical field [0001] The invention relates to a car anti-theft method, in particular to a car anti-theft control method based on key detection and fingerprint identification, which belongs to the field of anti-theft. Background technique [0002] Along with the development of economy and the progress of society, the quantity and popularity of automobiles are all increasing day by day, meanwhile the problem of automobile anti-theft is also highlighted gradually. Automobile anti-theft devices in the prior art mainly contain electronic anti-theft devices and network anti-theft devices. The electronic anti-theft device can emit sound and light to deter intruders, and if an intrusion is found, the ignition can be locked or started to achieve the purpose of anti-theft. The network anti-theft device adopts the combination of GPS satellite positioning system and mobile communication system. In addition to locking the ignition or starting to achieve the purpose of anti-theft, it a...

AI Technical Summary

Problems solved by technology

[0005] The car anti-theft devices in the prior art all adopt the mode of active monitoring, adopt various sensors to detect whether the car theft occurs, and then send out alarm information, which has played a certain role in anti-theft, but there are still the following problems: the false alarm rate is high , affect the mood of the car owner himself and the tranquility of the surrounding residents and pedestrians, and also increase the noise pollution in the city; adopt the method of active monitoring, the anti-theft device is always in the working mode when the car is not started, which greatly increases the burden on the level of the car

Although this invention can be used for car anti-theft, it needs to be further optimized on the anti-theft strategy
