Adaptive detection method, device, and anti-theft system for abnormal interruption of wheel motion signal

Abstract

This manual provides an adaptive detection method, device and anti-theft system for abnormal interruption of wheel movement signals. In an embodiment of the method, the time span in which the vehicle history is interrupted can be stored, and at the same time, whether the vehicle wheel signal is interrupted can be detected in real time. Compare the time difference from the power outage to the occurrence of the interrupt signal with the power outage span threshold in the interrupt time queue that has been interrupted in the storage history, and according to the comparison result, it is determined that the interrupt signal of the wheel signal of the currently detected power outage target vehicle is normal interrupt or abnormal interrupt. The solution of this embodiment can be adapted to different types and / or different target vehicles, and can effectively and adaptively identify whether the interruption signal of the wheel movement signal is abnormal under different types and / or vehicle conditions. Adopting the solutions of the embodiments in this specification can reduce the situation that the interruption caused by the normal wheel movement of the vehicle is ignored, effectively guarantee the anti-theft performance of the vehicle, and improve the user service experience.

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
