Infrared alcohol detection system

Abstract

The invention discloses an infrared alcohol detection system.The infrared alcohol detection system comprises a microprocessor, a driving circuit, an infrared sensing system, an amplifying circuit and an A / D switching circuit.The microprocessor, the driving circuit, the infrared sensing system, the amplifying circuit and the A / D switching circuit are connected in sequence.The A / D switching circuit is connected with the microprocessor.The infrared sensing system is a dual-channel infrared sensing system.The infrared alcohol detection system has the advantages that due to the design of the infrared sensing system, detection data can have the high disturbance resistance; a wireless transmission module and a background terminal server are cooperated for use, on the one hand, data can be synchronously transmitted in real time, and data accumulation is effectively avoided; on the other hand, an operator can perform real-time checking; the using safety and reliability of the system are improved through a fingerprint recognizer.

Description

technical field [0001] The invention relates to the technical field of alcohol detectors, in particular to an infrared alcohol detection system. Background technique [0002] The alcohol detector mainly refers to the breath alcohol content detector. It is a law enforcement detection tool specially designed for the police. The police on duty can use it to specifically deal with the drinking amount of the drinking driver, effectively reducing the occurrence of major traffic accidents. It can also be used in other occasions to detect the alcohol content in the exhaled breath of the human body, so as to avoid casualties and property losses. It can also be used in enterprises that prohibit drinking after work in high-risk areas. The alcohol detectors used by enterprises are not portable, but wall-mounted alcohol detectors. Advantages, in order to be more suitable for enterprises and institutions, the wall-mounted type has added a series of functions such as card swiping attendan...

AI Technical Summary

Problems solved by technology

[0003] At present, in some alcohol gas detection methods in our country, although the sensitivity of the sensitive unit used is very high, the accuracy of the analysis is relatively poor due to the interference of the background gas; in addition, some existing alcohol gas test equipment is bulky, Complicated operation, rough interface, lack of humanity and intelligence

However, the existing alcohol detectors, while storing data, often need to manually process the data when storing a certain value, that is, upload the data for processing, and cannot perform synchronous operations with real-time data.
