Problems solved by technology
However, there are problems when the safety monitoring system is used to monitor fires: it can only monitor the gas changes in the air but cannot detect the coal seam spontaneous combustion in the goaf
However, there are great shortcomings: a large number of pipelines need to be laid, which is not only costly, but also requires careful maintenance, otherwise pipeline damage will easily occur, resulting in inaccurate data at monitoring points, misleading personnel to judge, and even delaying fire fighting at critical times opportunity
The monitoring period is long, and it is impossible to upload data within 24 hours; 3. The software operation is complex, requiring manual intervention, and it is impossible to realize unattended automatic operation

Embodiment Construction
[0031] Such as figure 1 As shown, a gas monitoring analyzer 100 according to an embodiment of the present invention includes: a getter pump 10, a gas chamber 20 and a chip 30;
[0032] The aspirator 10 is used to collect gas samples from the goaf 50 and store them in the gas chamber 20;
[0033] The chip 30 is used to sample and analyze the gas sample in the gas chamber 20 , obtain an analysis result, and send the analysis result to the ground monitoring host 200 .
[0034] Wherein, the suction pump 10 is a common electric pump on the market, which can suck gas into the pump cavity and discharge it through the exhaust port.
[0035] Wherein, the air chamber 20 is an airtight area, and the sensing elements (sensing heads) of various sensors can be stored inside, which is convenient for the sensors to collect and analyze.
[0036] Among them, the chip 30 is equivalent to a processor, and can also be used as an analysis unit of the gas monitoring analyzer 100; the chip 30 mainl...

The invention relates to a gas monitoring analyzer and a fire early warning monitoring system, the gas monitoring analyzer comprises a getter pump, a gas chamber and a chip, the getter pump is used for collecting a gas sample of a goaf and storing the gas sample in the gas chamber, and the chip is used for sampling and analyzing the gas sample in the gas chamber to obtain an analysis result and sending the analysis result to a ground monitoring host. According to the invention, monitoring of different gas changes in the goaf is realized through the gas monitoring analyzer and the constructed fire hazard early warning monitoring system, a user can conveniently acquire real-time gas indexes, the fire hazard is effectively prevented, and meanwhile, the natural occurrence of a coal seam in the goaf can be monitored in real time, so that the safety of the goaf is improved. The probability of occurrence of mine fire and gas explosion is reduced, so that the occurrence of mine safety accidents is reduced.
Description
technical field [0001] The invention relates to the technical field of fire early warning and monitoring, in particular to a gas monitoring analyzer and a fire early warning and monitoring system. Background technique [0002] my country's coal industry has entered a rare period of historical development opportunities, but with the gradual increase in production scale, various safety issues follow. Therefore, the "digital mine" advocated by the state hopes to and other means to improve the level of coal mine safety production and management efficiency. [0003] At present, there are mainly two methods for monitoring underground fires. The first type: safety production monitoring system, the second type: beam tube monitoring system. [0004] The safety production monitoring system is equipped with various sensors such as methane, carbon dioxide, oxygen, hydrogen sulfide, nitrogen dioxide, wind speed, temperature, dust, water level, smog, power on, off, and power supply. The ...
