Underground gas real-time monitoring system

Abstract

The invention relates to an underground gas real-time monitoring system. The underground gas real-time monitoring system comprises a processor module, a gas detection module, a wireless communication module and a human-computer interaction module, wherein the processor module is respectively connected with the gas detection module, the wireless communication module and the human-computer interaction module; the gas detection module comprises at least one group of gas sensor, signal amplifier and A / D (analog / digital) conversion circuit, all groups of gas sensor, signal amplifier and A / D conversion circuit are arranged in different underground areas, and detected gas concentration data is transmitted to the processor module; an antenna is arranged in the wireless communication module, and the gas concentration data is transmitted by the wireless communication module to a remote monitor; the human-computer interaction module comprises a display device and a keyboard, wherein the display device is used for displaying the gas concentration data, and the keyboard is used for setting the parameters inside a processor; the output end of the processor module is also connected with a ventilating device. By adopting the underground gas real-time monitoring system, not only can the real-time in-situ and remote monitoring be carried out, but also the automatic ventilation can be realized when the gas concentration exceeds a preset value.

Description

technical field [0001] The invention relates to an underground gas real-time monitoring system, which belongs to the technical field of explosion-proof safety products. Background technique [0002] Previously, the traditional domestic gas monitoring system used wired data transmission, which made the monitoring location relatively limited, and with the movement of the coal mine excavation surface, re-wiring was required, which prolonged the operation time. In addition, when there is a problem with the wired monitoring equipment, it can only be maintained in the mine, which relatively increases the difficulty of maintenance. [0003] Chinese patent CN203067034U provides a coal mine gas wireless monitoring device, which solves the problem of limited monitoring position and difficult maintenance in the wired gas monitoring system, but only performs remote monitoring function. , unable to perform automatic ventilation, and unable to keep an eye on the gas concentration at the ...
