An intelligent detection system for gas concentration

Abstract

The invention discloses a gas concentration intelligent detection system, which is characterized in that: the system is composed of a gas environment parameter collection platform based on a wireless sensor network and a gas multi-level early warning module, and the gas environment parameter collection based on a wireless sensor network The platform realizes the detection of gas environment parameters, gas concentration adjustment and early warning. The gas multi-level early warning module is composed of a gas interval number neural network model, an interval number prediction model and an interval number GRNN neural network gas grade classifier; the invention effectively solves the problem of existing The gas concentration detection system does not detect the gas concentration according to the characteristics of non-linearity of gas changes, large hysteresis, and large working area and complex gas concentration changes, which greatly affects the accuracy of gas concentration detection.

Description

technical field [0001] The invention relates to the technical field of gas detection automation equipment, in particular to an intelligent gas concentration detection system. Background technique [0002] In the production process of coal, oil and natural gas, fast and accurate monitoring, forecasting and automatic control of flammable, explosive, toxic and harmful gases have become one of the important problems to be solved urgently. Effective monitoring and control of environmental pollution requires a series of new sensing and measurement technologies, especially detection instruments and systems that can continuously monitor the content of harmful pollutant gases in the atmosphere. In order to effectively reduce the occurrence of accidents and the pollution to the environment, it is necessary to set up instruments and equipment that can detect gas online in real time and quickly. According to the actual needs of the industrial and agricultural production process, this p...
