Harmful gas detection system

Abstract

The invention provides a harmful gas detection system, comprising: a monitoring terminal arranged in a remote monitoring center, a gas detection device and a filter exhaust device arranged in a monitoring station; the gas detection device is connected to the monitoring terminal through a wireless network; the The gas detection device includes a toxic gas detector; the monitoring terminal includes a processor, a display and an alarm, the processor can receive the information sent by the gas detection device, and process the information, the display displays the information, and the alarm is on When the harmful gas exceeds the standard, it will alarm; at the same time, the server controls the filter exhaust device to exhaust. The invention can detect the harmful gas in the production site and the production process with high sensitivity, and give an alarm when the concentration is abnormal, so as to improve the monitoring ability of the harmful gas.

Description

technical field [0001] The invention relates to a harmful gas detection system. Background technique [0002] In some special construction sites such as factories and mines, there are often situations where harmful gases exceed the standard, and some harmful gases are prone to fire, explosion and other dangers under certain conditions, such as a large amount of methane (CH4) produced during coal production and processing 4 ) and carbon monoxide (CO) and other flammable, explosive and harmful gases have brought a series of problems to coal mine safety and environmental pollution. Therefore, it is very important to perform high-sensitivity detection of harmful gas concentrations in some production sites and production processes. [0003] At present, most of the precision instruments for measuring gas concentration are optical fiber single gas sensors, and conventional transmission absorption gas cells are mostly used as the core device of optical fiber gas sensors, but there ...

Problems solved by technology

[0003] At present, most of the precision instruments for measuring gas concentration are optical fiber single gas sensors, and conventional transmission absorption gas cells are mostly used as the core device of optical fiber gas sensors, but there are coupling problems between optical fibers and discrete optical components, complex alignment, and stable temperature The performance is not ideal, the anti-seismic performance is poor and the detection accuracy is not high.
