Embodiment Construction

[0007] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0008] Now combined with figure 1 As shown, a vehicle-mounted drunk driving alarm of the present invention includes a single-chip microcomputer U1, an alcohol sensor J2, a 24LC64 chip U2, an LED light D1-D8, a buzzer BUZ1, and a relay RL1 with a model of AT89C51. The model is The 19 pin of the microcontroller U1 of the AT89C51 is connected to one end of the capacitor C7, the 19 pin of the microcontroller U1 of the model AT89C51 is connected to one end of the crystal oscillator X1, and the 18 pin of the microcontroller U1 of the model AT89C51 is connected to one end of the capacitor C8. The 18 pin of the single-chip microcomputer U1 of AT89C51 is connected to the other end of the crystal oscillator X1, the other end of the capacitor C7 and the other end of the capacitor C8 are grounded to GND, and the 9 pin of the single-chip microcomp...

Abstract

The invention provides a vehicle-mounted drunk driving alarm, which solves the problem that the existing vehicle-mounted equipment does not have a drunk driving alarm. The technical scheme comprises asingle chip microcomputer U1 of a model AT89C51, an alcohol sensor J2, a chip U2 of a model 24LC64, and an LED lamp D1-D8, buzzer BUZ1 and relay RL1. The alcohol concentration detected by the alcoholsensor J2 is transmitted to a single chip microcomputer U1 after being subjected to a partial pressure of a resistor R12, and the single chip microcomputer U1 controls the LED lamp D1-D8 emit light to detect whether that drive is alcohol or not. When the alcohol concentration reaches a certain value, the buzzer BUZ1 alarms, and the automobile engine cannot be star, thus fundamentally solving theproblem of drunk driving, and has high practicability and good application prospect.

Description

Technical field [0001] The invention relates to the technical field of alarms, in particular to a vehicle-mounted drunk driving alarm. Background technique [0002] The problem of road traffic safety is a global issue. All countries are facing the crisis of road traffic safety caused by traffic accidents. According to the accident investigation of the World Health Organization, about 60% of traffic accidents are related to drinking and driving. It is listed as the main cause of death in a car accident, so it is not possible to drive after drinking. However, some drivers will knowingly commit the crime and become "road killers". The existing on-board equipment does not have a drink-driving alarm and cannot prompt the driver to avoid this. This kind of tragedy needs a car alarm for drunk driving. Summary of the invention [0003] In view of the above situation, in order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a vehicle-mount...
