Novel alcohol test controller system for automobile

Abstract

The invention discloses a novel alcohol test controller system for an automobile. The system comprises the automobile, an alcohol controller and a single-chip microcomputer, wherein the alcohol controller is installed in the right-hand position of an automobile cab driver, a palm sweat alcohol content sensor is installed in an automobile steering wheel and connected with the alcohol controller, the alcohol controller is connected with the single-chip microcomputer arranged in the alcohol controller through an A / D (analog to digital) conversion circuit, the single-chip microcomputer is connected with a relay switch on the automobile, the alcohol controller is connected with an alarm device, and the alcohol controller is connected with a microphone. Through the structural design, the system has the characteristics that the system can judge whether the driver is a drunk driver or not intelligently to guarantee the safety of the driver, the workload of people such as traffic polices and the like is reduced, the alcohol sensor is high in sensitivity, the controller is small in size and low in power consumption, a voltage comparison function is provided, the manufacturing cost is lower than that of an expiration alcohol tester, implementation and use methods are simple and easy to popularize, corrupt practices, for example, replacement of the driver by other people for blowing and the like, are effectively prevented, and the system is high in reliability.

Description

technical field [0001] The invention relates to a device for preventing drunk driving and drunk driving, in particular to a novel automobile alcohol test controller system. Background technique [0002] Traffic accidents have become the "first public hazard" that threatens the safety of human life. Every year, 500,000 people die in car accidents around the world. The basic factors that cause traffic accidents are people, vehicles, roads, environment and management, among which the driver's own factors account for 70%. Drunk driving is one of the important factors in driving accidents. According to statistics from various countries in the world, 30% to 50% of traffic accidents are caused by drinking and driving. my country's traffic department reports that the traffic accident rate of drunk driving is at least 5-6 times higher than that of ordinary people. my country's traffic laws and regulations stipulate that drinking and driving is prohibited. In our survey, 11.99% o...

Problems solved by technology

At present, there are a lot of driver drunk driving controllers on the market, which mainly detect the alcohol content by blowing air and alcohol detection equipment. If the alcohol content exceeds the standard, the car igniter will be cut off so that it cannot be started, so as to achieve the control function, but there are always some disadvantages , For example, the driver after drinking can find someone else to blow it on his behalf, the controller for driving after drinking will not be able to play its due role, and cannot fundamentally solve the problem of driving after drinking, and due to factors such as reliability, practicability, and cost without being promoted
