Automobile remote control key with drunk driving inhibition function

Abstract

The invention provides an automobile remote control key with a drunk driving inhibition function. The automobile remote control key is characterized in that a finger pressing type alcohol detector, a 555 integrated circuit and a silicon controlled rectifier VS are added in the circuit based on an original automobile remote control key circuit; a monostable trigger is established through the 555 integrated circuit; the output end of the alcohol detector is connected with two-foot trigger end of the 555 integrated circuit; the three-foot output end of the 555 integrated circuit controls the silicon controlled rectifier VS, so as to further control an unlocking key K1. According to the automobile remote control key, the finger pressing type alcohol detector is integrated, when a driver presses the unlocking key with a finger, the alcohol detector synchronously detects the alcohol concentration of the finger, if the situation that the alcohol concentration exceeds the standard is detected, the unlocking key is locked, and even if the unlocking key is pressed, the car door cannot be opened, so that a drunk person is inhibited from entering the automobile cab in the point of view of technology, and the purpose that drunk driving is completely inhibited is achieved.

Description

technical field [0001] The invention relates to a car remote control key, in particular to a car remote control key with the function of prohibiting driving after drinking, and belongs to the technical field of applied electronics. Background technique [0002] In order to maintain road traffic order and ensure safe driving, the Ministry of Public Security has issued a number of new regulations on dealing with traffic violations in recent years. The special action to strictly investigate illegal behaviors of drunk driving, however, some drivers will still take chances and take risks, drink and drive, which will lead to serious traffic accidents. Therefore, it is difficult to fundamentally curb drunk driving only by the driver's self-consciousness. [0003] In recent years, the DADSS driver alcohol monitoring safety system launched by the American Automobile Manufacturers Automobile Safety Alliance has focused on the development of two directions: finger press detection tech...

AI Technical Summary

Problems solved by technology

In China, relevant scientific and technical personnel have also developed a fingerprint-type drunk driving prohibition system. After the vehicle is installed with this system, the alcohol sweat detection will be connected with the car startup program, and the driver's finger sweat can be judged by pressing the finger on the corresponding alcohol detector. Whether the alcohol concentration in the vehicle exceeds the standard, if it exceeds the standard, the ignition or EFI circuit remains disconnected, and the vehicle cannot be started
