Abstract

The invention discloses a harmful gas monitoring system based on a detection rectifying circuit; the harmful gas monitoring system is simple in structure and easy to implement. The harmful gas monitoring system adopts a novel pyroelectric infrared detector, thus being capable of detecting the concentrations of multiple harmful gases at the same time; due to the optimal design of a light source modulation and signal conditioning circuit, the external disturbance is effectively reduced, and the system error is reduced. A digital signal processor (DSP) has powerful operation processing ability, so that the measurement accuracy and speed of the system are improved; CAN bus communication is convenient for remote monitoring. After the system is used, the concentrations of multiple harmful gases can be monitored in real time.

Description

technical field [0001] The invention relates to a harmful gas monitoring system, in particular to a harmful gas monitoring system based on a detection and rectification circuit, belonging to the field of harmful gas monitoring and control. Background technique [0002] With the acceleration of urbanization and industrialization, the impact of various harmful gases on industrial and agricultural production, natural environment and daily life is becoming more and more serious, which has aroused widespread concern of the whole society. Excessive concentrations of harmful gases in the local environment and industrial sites will seriously endanger people's health. Therefore, it is of great significance to monitor the concentration of harmful gases in certain specific areas. Compared with traditional gas concentration measurement methods, infrared absorption spectroscopy has many advantages such as high measurement accuracy, fast response speed, good stability, strong anti-interf...
