An early warning system for car tamper-proof locks based on contact point detection

Abstract

The invention discloses an automobile picklock-prevention early warning system based on contact point detection. The system works according to the method comprising the steps that a control module obtains vibration information in a preset area of a lockhole of a target vehicle through a vibration signal obtaining module and judges whether the preset area of the lockhole of the target vehicle vibrates or not, when the judgment result is yes, the control module obtains the lock state of the target vehicle through a lock state obtaining module and judges whether or not the lock state of the target vehicle is changed into an opening state from a closing state, when the judgment result is yes, the control module obtains contacted signals of n contact points preset in the lockhole of the targetvehicle through the contacted signal obtaining module, counts the number m of the contacted points of the n contact points, makes m compared with a preset threshold, and controls an alarm sending module to work according to the comparison result and / or controls a video collection module to work through an instruction, wherein m is smaller than or equal to n.

Description

technical field [0001] The invention relates to the technical field of automobile safety and defense, in particular to an automobile anti-picking lock early warning system based on contact point detection. Background technique [0002] At present, the method of improving the anti-theft performance of automobile door locks is mainly to increase the strength of the door lock itself and optimize the structure of the lock cylinder. The purpose of this method is to prevent violent lock picking, but it cannot prevent technical lock picking. Technical lock picking refers to criminals Under the condition of being familiar with the structure of the lock cylinder, the lock cylinder is detected by a specific tool, so that the shrapnel in the lock cylinder is in the unlocking position, and then the connecting rod is driven by rotating the lock cylinder to open the door lock. [0003] Now when car owners open the car door locks, most of the time they choose to use the car remote control ...

[0002] At present, the method of improving the anti-theft performance of automobile door locks is mainly to increase the strength of the door lock itself and optimize the structure of the lock cylinder. The purpose of this method is to prevent violent lock picking, but it cannot prevent technical lock picking. Technical lock picking refers to criminals Under the condition of knowing the structure of the lock cylinder, use a specific tool to detect the lock cylinder, so that the shrapnel in the lock cylinder is in the unlocking position, and then drive the connecting rod to move by rotating the lock cylinder, so that the door lock is opened

[0003] Now when car owners open the car door locks, most of the time they choose to use the car remote control to unlock. In this way, the safety protection of the car door lock itself is not perfect. With the rapid development of the automobile industry, the degree of automobile electronics is becoming more and more The higher the level, the higher the requirements for vehicle anti-lost safety protection. Now the anti-theft safety of automobiles must take into account all aspects and make products more intelligent in order to satisfy customers.
