Compound effluvium electronic nose system and method

Abstract

The invention discloses a compound effluvium electronic nose system and method. The system comprises a sensor array, a signal conditioning circuit, a single chip microcomputer, an industrial personal computer and other components, wherein the sensor array, the signal conditioning circuit and the single chip microcomputer are connected sequentially, and the single chip microcomputer is connected with the industrial personal computer through an RS485 serial port. Combined with the method, the compound effluvium electronic nose system avoids the defects in the prior art that a remote terminal for information storage of gas to be detected occasionally results in delay of delivery time due to the distance of an RS485 serial port line, the incompatibility in data transmission of a plurality of data transmission media has adverse consequences on the correctness and storage operation of the information storage device of the gas to be detected, the cooling property is poor, and particulate impurities float into a control cabinet and result in that the components of the industrial personal computer are invaded.

Description

technical field

[0001] The invention belongs to the technical field of electronic noses, and in particular relates to a compound malodorous electronic nose system and method. Background technique

[0002] Through the study of the olfactory mechanism of mammals, it is found that mammals do not know the chemical composition and concentration of the recognized smell, but they can accurately judge the type of smell, such as fragrance, sour, spicy, hemp, smell and their Humans have different olfactory sensitivities, some people are weaker, and some people are particularly sensitive to smells. Some people who are born with a sensitive sense of smell have been trained to become professional inspectors. They can judge the type and quality level of their perfume or wine by smell, which provides a theoretical basis for simulating the human olfactory system. It can be seen that the electronic nose mainly includes three parts: sensor array, signal processing and pattern recognition sys...
