Design scheme of intelligent automobile door automatic locking device

Abstract

The invention discloses a design scheme of an intelligent automobile door automatic locking device, and belongs to the technical field of automobile electrical appliances. The intelligent automobile door automatic locking device comprises a double-display circuit unit, basic automobile doorframe units, an automobile doorframe input system, an automatic input identification circuit unit, an automatic input time-delay circuit unit, a restoration identification circuit unit, a restoration control circuit unit, a locking circuit unit, an unlocking circuit unit, an execution control circuit unit, a device power supply control circuit unit and a battery power supply. An automobile center control lock is automatically locked after an automobile door closing process is finished; an alarm is switched on, and furthermore, double insurances are implemented in a process of carrying out important actions; operating states of important components of the device are automatically detected in a door closing process, when a failure happens, the result of failure state content detected on the failure components can be automatically displayed, the automatic locking device is convenient to maintain, meanwhile, the automatic locking device overcomes the faults and is automatically locked in a certain time, the phenomenon of false locking of an automobile caused by the use of a remote-control interference device by a lawbreaker is avoided, the phenomenon of unlocking and burglary by a duplicator is avoided, and the safety of the automobile is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of automobile electric appliances. Background technique [0002] At present, there are serious safety problems in the investment of the car's central control lock and alarm system. Its operation method is to take out the remote control key after all the doors are closed, press the remote control key to lock the central control lock of the car door, and The alarm system is put into operation. Its existing problems are: [0003] 1. It is not safe enough. When criminals use a car remote control jammer with sufficient power nearby, it can interfere with the signal of the car remote control and make it malfunction. Since the jammer is not limited by the types of vehicles and remote controls when it is used, fixed codes, special codes, and rolling codes can interfere. As long as the interference power is large enough, any model can interfere, so that the car cannot be locked. order, resulting in false vehicle l...

AI Technical Summary

Problems solved by technology

[0003] 1. It is not safe enough. When criminals use a car remote control jammer with sufficient power nearby, it can interfere with the signal of the car remote control and make it malfunction.

Since the jammer is not limited by the types of vehicles and remote controls when it is used, fixed codes, special codes, and rolling codes can interfere. As long as the interference power is large enough, any model can interfere, so that the car cannot be locked. command, resulting in the false lock of the vehicle, which is unsafe and causes great hidden dangers

What's more, some lawbreakers can also use a special electronic device called a "duplicator". When the owner is using the remote control to lock the lock, this electronic device can capture the radio frequency signal and password signal of the remote control. , criminals will use this instrument to safely and boldly copy the password signal for unlocking and stealing

[0004] 2. The operation is not convenient enough. After the car door is closed, the remote control key must be taken out and pressed to put in the remote control key.
