Drunk-driving detector

Abstract

The invention discloses a drunk-driving detector. The drunk-driving detector comprises a housing, a signal acquisition chamber and a signal processing installation chamber, the signal acquisition chamber and the signal processing installation chamber are respectively positioned at an upper half part and a lower half part in the housing, an air outlet, a display screen, an operation button, and analarm lamp are arranged at the right side of the housing from up to down, a tail part is a strip-hanging hole, the air intake is arranged at the signal acquisition chamber, a sensing device is arranged at an inner wall, a single-chip microcomputer, ADC and a cell are arranged in the signal processing installation chamber, the single-chip microcomputer is electrically connected with the ADC, the operation button, the sensing device and the alarm lamp, the ADC is electrically connected with the display screen, the cell supplies power to the single-chip microcomputer, the ADC and the display screen. The drunk-driving detector has the advantages of simple structure, reasonable design, convenient carrying, high detection sensitivity, and good responsiveness, has obvious effect to investigate and treat drunk driving, and can effectively increase the law enforcement efforts of law enforcement officers.

Description

technical field [0001] The invention belongs to the technical field of sensors, in particular to a drunk driving detector. Background technique [0002] In order to obtain information from the outside world, people must rely on sensory organs. However, relying on people's own sensory organs alone is far from enough for their functions in the study of natural phenomena and laws and production activities. To accommodate this situation, sensors are needed. Therefore, it can be said that the sensor is an extension of the human five senses, also known as the electric five senses. With the advent of the new technological revolution, the world has entered the information age. In the process of using information, the first thing to solve is to obtain accurate and reliable information, and sensors are the main ways and means to obtain information in the natural and production fields. [0003] With the continuous enrichment of materials and the continuous improvement of people's l...

Problems solved by technology

At present, most of the principles of alcohol detection are based on the principle of chemical reaction, which takes time, is inconvenient to carry, and has large errors, which is not conducive to law enforcement officers.
