Self-adaptive wheel movement signal abnormal interruption detection method and device and anti-theft system

Abstract

The invention provides a self-adaptive wheel movement signal abnormal interruption detection method and device and an anti-theft system. In one embodiment of the method, the time span with an interrupted vehicle history can be stored, and meanwhile, whether an interruption signal of a vehicle wheel movement signal exists or not can be detected in real time. The time difference from power failure to interruption signal occurrence is compared with a power failure span threshold in an interruption time queue in which interruption occurs in storage history, and whether the interruption signal of the wheel movement signal of a current detection power failure target vehicle is normal interruption or abnormal interruption is determined according to a comparison result. The scheme of the embodiment can adapt to different types and / or different target vehicles, and can effectively and adaptively identify whether the interrupt signal of the wheel movement signal is abnormal or not under the condition of different types and / or vehicles. By the adoption of the scheme, the situation that interruption caused by normal rotation of the vehicle is ignored can be reduced, the anti-theft performanceof the vehicle is effectively guaranteed, and the user service experience is improved.

Description

technical field [0001] The embodiments of this specification belong to the field of vehicle anti-theft technology data processing, and in particular relate to an adaptive detection method, device and anti-theft system for abnormal interruption of wheel motion signals. Background technique [0002] With the development of sharing economic technology, shared bicycles, shared electric vehicles, shared cars, etc. have brought great convenience to people's travel. How to effectively prevent or monitor the theft of shared vehicles and reduce the loss of shared vehicles has become an urgent problem for shared service providers to solve. [0003] At present, in a wheel motion signal detection method used in the field of vehicle anti-theft, the main principle is to use the electromotive force generated by cutting the magnetic induction line when the vehicle wheel rotates. Therefore, some equipment can be used to detect whether the electromotive force is generated, and then judge Whe...

AI Technical Summary

Problems solved by technology

In practical applications, it often occurs that the power isolation of some anti-theft power controllers that provide vehicles with anti-theft actions is not enough, resulting in an interrupt being triggered on the interrupt detection pin for a period of time after power failure, thereby continuing to trigger anti-theft actions

In this way, a car may be in an anti-theft state all the time, seriously affecting the anti-theft performance of the vehicle and user experience
