Central lock automatic locking device with LED display self-checking function

Abstract

The invention provides a central lock automatic locking device with an LED display self-checking function and belongs to the technical field of automotive electrical appliances. The central lock automatic locking device is composed of a basis door frame unit, an input operation system, a sampling system, a detection display system, an identification circuit unit, an input circuit unit, a zero clearing releasing circuit unit, a control circuit unit, a power management unit, a battery supply unit and an operating mechanism execution unit. By adopting the central lock automatic locking device with the LED display self-checking function, the locking principle of existing products is changed thoroughly. The central lock automatic locking device can automatically shut off a central lock system in a car after completion of the car door closing process, automatically input an alarm unit, automatically shut off and lock an oil circuit, automatically detect the operating states of important parts of the system, automatically give a prompt when the system breaks down during operating, conduct LED display on the faulty system unit, facilitate timely maintenance and guarantee the car safety.

Description

technical field [0001] The invention belongs to the technical field of automobile electric appliances. Background technique [0002] At present, the central control lock and alarm system of automobiles are important safety protection devices for automobiles, and they have played a significant role in the long-term use. The special electronic equipment called "duplicator" has caused a great negative impact on the important safety protection of automobiles, because the investment of the existing automobile central control lock and alarm system is generally manual input, that is, the input of the car door After all are closed, take out the remote control key, press the remote control key to lock the door central lock, and put the alarm system into operation. If criminals use a car remote control jammer with sufficient power nearby, they can interfere with and intercept the signal of the car remote control, causing it to fail. Since the jammer is not limited by the types of ve...

Problems solved by technology

[0004] In order to change the investment in the locking and alarm system of the current car door central lock, most of them use manual operation, which is both cumbersome and inconvenient, and more importantly, the status quo is not high in safety. The automatic locking device of the central control lock with the self-test function can completely change the principle of locking the existing products. It is a kind of automatic closing of the central control locking system in the car after the door closing process is completed. , automatically turn on the alarm, automatically close and lock the oil circuit, and automatically detect the operating status of important parts of the system. When the system operating status fails, it will automatically give a voice prompt and digitally display the failed system unit, which is convenient Timely maintenance to ensure car safety
