Methane sensor system

Abstract

The invention relates to the technical field of gas detection, in particular to a methane sensor system. The methane sensor system comprises a plurality of movable sensing devices for being worn, wherein each movable sensing device comprises a methane sensor, a wireless receiver, a wireless transmitter and a warning device, each methane sensor is used for detecting the concentration of methane and sending out an original warning signal; the wireless receiver is used for receiving the wireless warning signal sent out from by the movable sensing device at the last level; each wireless transmitter is used for sending out the wireless warning signal of the corresponding level to the movable sensing device at the next level according to the wireless warning signal and/or an original warning signal and is connected with the corresponding methane sensor and the corresponding wireless receiver respectively; the warning device is used for sending out warning information according to the wireless warning signal and/or the original warning signal and is connected with the methane sensor and the wireless receiver respectively. Through the application of the methane sensor system, users obtain warning information and transfer wireless warning information to others at the same time level by level, so that the warning effect and the guiding capacity are notably improved.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to a methane sensor system. Background technique [0002] With the development of my country's economic construction, various protective devices are widely used in many fields. Among them, for areas with hidden dangers of methane leakage, methane sensors need to be used for detection and protection. [0003] In recent years, the requirements for the alarm effect and guidance ability of methane sensor prompts and alarms have become higher and higher. Therefore, improving the alarm effect and guidance ability has become the design goal. [0004] In the prior art, the methane sensor monitors the methane concentration in the ambient air, and when the concentration is higher than a preset value, the methane sensor sends out an alarm message, including sound and light alarm signals, through detection. For example, in the process of coal mine operation, when the methane sensor on th...

AI Technical Summary

Problems solved by technology

When the mine area is large and there are many people, when the local methane concentration exceeds the standard, the methane sensor on the back of the miner in the excessive area sends out an alarm signal, and the miners who are far away cannot evacuate in time without receiving this alarm signal, which delays The time for self-rescue and hoisting is shortened, which reduces the safety guarantee ability of the overall underground operators

[0005] In the above prior art, defects such as low alarm effect and guiding ability of the methane sensor have become technical problems to be solved by those skilled in the art
