Gas detection system based on gas sensor

Abstract

The invention provides a gas detection system based on a gas sensor. The gas detection system comprises an optical emission module, an acquisition module, a light detection module, a conditioning module and a control module. The light emission module generates infrared light. The acquisition module absorbs the characteristic spectrum of infrared light. The light detection module converts infraredlight into electrical signals. The conditioning module conditions the electrical signals to produce digital signals. The control module processes the digital signals and then backs up and displays theprocessing results to realize the detection of gas composition and concentration. The gas detection system is free of a special light absorption gas chamber, a light reflection device and a special air extraction system, reduces the cost of the gas sensor and improves the integration and accuracy of the gas sensor. The gas sensor does not need power in work so that the gas detection system has low power consumption and is not affected by the high voltage and strong magnetic field in the electric power environment and the system can stably work in a long term.

Description

technical field [0001] The invention relates to a detection system, in particular to a gas detection system based on a gas sensor. Background technique [0002] With the continuous expansion of the power grid, the influence of power grid failures is also gradually increasing. Power transmission and distribution equipment is the basic element of the power grid, and it is also the main source of power grid accidents. Some equipment with a long running time, due to the external environment, defects left in manufacturing, and long-term stresses such as electricity, heat, and mechanical forces during operation, make their strength continuously decline, resulting in the leakage of the gas used for insulation inside the equipment to the outside. Or flammable or toxic gases are mixed into the production inspection environment. When the latent faults develop to a certain extent, it is easy to cause equipment failures, threaten personnel safety, and may expand into power grid accide...
