Abstract

The invention belongs to the technical field of safety and discloses an air gas detection system and method based on low-temperature high-speed carbon atoms, the system comprises an underground working platform and a management terminal, the underground working platform comprises a gas purification module, a particle accelerator and a charge coupling detector, the gas purification module is used for purifying underground air to obtain a pure methane gas mixture, and the particle accelerator is used for accelerating carbon atoms, so that the accelerated carbon atoms and the pure methane gas mixture collide and are input into the charge coupling detector; the charge coupling detector is used for measuring the carbon atom content in the air by adopting a spectrum technology, converting the carbon atom content in the air into an electric signal and sending the electric signal to the management terminal, and the management terminal is used for converting the current signal into the corresponding gas content in the air, so that the gas content in the coal mine air can be monitored in real time.

Description

technical field [0001] The invention relates to the technical field of safety detection, in particular to an air gas detection system and method based on low-temperature and high-speed carbon atoms. Background technique [0002] In coal mining, a certain amount of gas will protrude from the coal seam, and the main component of gas is methane. The existing technology for the detection of gas content in the air is: in the coal mine safety detection system, it is used in coal mine shafts, and the methane sensor is directly used for detection. The methane concentration is continuously monitored at the mining face, goaf, return air roadway, and electromechanical cavern. Specifically, a detection box is used, and a push-pull mechanism and an adjustment mechanism are installed inside the detection box. The air inside the methane sensor will pass through the A / D The conversion will convert the analog signal into a digital signal. This method of using a sensor to convert the analog s...

AI Technical Summary

Problems solved by technology

[0003] (1) The structure of the existing detection device is complicated. The analog signal collected by the push-pull mechanism and the adjustment mechanism combined with the sensor is an improvement from the device structure itself. It is impossible to directly convert the gas content in the air into an electrical signal. It is necessary to collect the analog signal first. After processing by the processor, it is converted into an electrical signal and then processed

[0004] (2) There are a lot of coal dust in the underground air, and there are a lot of impurities in the coal dust, which interferes with the detection of gas content, and the measurement results obtained are inaccurate
