Abstract

The invention relates to detection system for an atmospheric pollution gas, and belongs to the technical field of environment protection. The detection system is used for the detection of air pollutants. The detection system is mainly characterized in that a single chip microcomputer PIC16F676 and a single chip microcomputer PIC12F675 are used as a control center for controlling the whole system; a software portion is written and programmed by using a module idea. Under the support of the software, the detection system has the advantages of intuitive display, easy operation, convenience for carrying and strong data processing capacity. Besides detection of the air pollutants, establishing a high-quality automatic detection system for air environment quality and having significant theoretical value and practical meaning for air protection and treatment, the detection system can be expanded to other occasions such as biology, medical treatment, food analysis and the like, is a novel portable energy-saving analysis system. The detection system is a novel air quality detection system integrating real time, intelligent, wireless and systematization together by using advanced computer technology, single chip microcomputer technology and wireless transmitter and receiver technology.

Description

technical field [0001] The invention relates to an air pollution gas detection system, which is used for the detection of air pollutants and belongs to the technical field of environmental protection. Background technique [0002] At present, the smoke released during industrial combustion is the main source of air pollution in cities, and smoke detection is an indispensable item in the atmospheric environment. In order to improve combustion efficiency, save energy, reduce air pollution, and control the fuel-air ratio in the combustion process, it is necessary to effectively measure the content of various components in the flue gas. Through the monitoring of flue gas, key pollution sources can also be determined and real-time monitoring of pollution sources can be carried out. However, in the past flue gas detection, from the collection of samples to the display of analysis results, there are many links. Not only the workload is heavy, but also the samples are easy to be po...
