Safety control device of starting of automobile

Abstract

The invention discloses a safety control device of the starting of automobiles, belonging to the field of electronic theft prevention of the automotives. The safety control device comprises an ignition switch, an inductor 1, a programmable controller, a relay, a power supply, an automobile starter and an inductor 2, wherein the programmable controller is respectively connected with the power supply, the inductor 1, the inductor 2 and the relay through a circuit; the relay is connected with the automobile starter; and the inductor 2 is electrically connected with the programmable controller. The invention has the advantages that every time a remote controller works, a code is immediately changed once correspondingly, and the code can not be easily duplicated or stolen, therefore safety is higher; in addition, the two inductors are treated as redundant structures, therefore the stability and the safety of an automobile precaution device are more ensured.

Description

technical field [0001] The invention relates to a safety control device, in particular to a safety control device for starting an automobile, and belongs to the field of automobile electronic anti-theft. Background technique [0002] The early car electronic anti-theft devices have the same set of passwords for the host and the remote control. The remote control transmits the password, and the host receives the password, thus completing various functions of the anti-theft device. This password transmission method is called the first generation of fixed code transmission method. . The application of the fixed code transmission method in the car anti-theft device is not popular. When the initial anti-theft device is applied to the market, the safety and reliability of the anti-theft device are still guaranteed. But in the market where the use of anti-theft devices has matured, the coding method is unreliable for three reasons: [0003] 1) The number of passwords is small, an...

AI Technical Summary

Problems solved by technology

[0003] 1) The number of passwords is small, and repeated codes are prone to appear, that is, the phenomenon that one remote control controls multiple vehicles

[0004] 2) After the remote control is lost, it is extremely unsafe to replace the remote control alone, unless it is replaced together with the host, but the cost is too high

[0005] 3) The security is poor, the password is easy to be copied or stolen, and the vehicle is easy to be stolen
