Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] The invention provides a mine gas monitoring method and system. In addition to providing the gas detection function, it can also send data to the ground control center in a wireless and wired manner, so as to further monitor the underground operation status.

[0032] like figure 1 As shown, it is a flowchart of a monitoring method according to an embodiment of the present invention. In this figure, in step 11, the gas concentration data is collected by the gas sensor on the mobile working unit, and converted into an electrical signal and transmitted to the central control chip. After the two poles of the element are heated to a certain temperature (usually about 400 degrees), the electric bridge connected to the two poles is in balance at this time, and when one of the two poles is placed in the gas, flameless combustion will ...

Abstract

The invention discloses mine gas monitoring method. It includes the following steps: using gas sensor to collect gas density data, transform to electrical signal, and send to center control chip; storing the electrical signal in storage after analog-digital conversion and sending it to data communication server by modem and wireless launching unit; transmitting gas density data to main control sever; accepting the image signal and transmitting to main control sever; collecting, analyzing, displaying, and reserving the signal, and sending various control signal to enter control chip. The invention also discloses the system. Compared with the current technique, the invention has the features to safe, reliable, flexible operation, and all-around function.

Description

technical field [0001] The present invention relates to a monitoring method and system, more specifically, to a mine gas monitoring method and system used in coal mines. Background technique [0002] In my country, due to backward coal mining technology, gas explosion accidents occur frequently, making the number of deaths in mine accidents in my country reach dozens or even hundreds of times that of foreign countries. In order to ensure the safety of underground workers, a safety monitoring method and system are urgently needed to minimize accidents. However, the existing gas detection devices often have a single function and are mostly fixed installations, which cannot prevent accidents in various ways. After the accident, it is impossible to provide effective help to the rescue work. Therefore, there is a need for a monitoring method and system that can monitor downhole operating conditions in real time and communicate with downhole workers, collect downhole environment...
