Abstract

The invention discloses a tunnel gas monitoring, recording and early-warning system and a monitoring method thereof. The early-warning system comprises a plurality of monitoring box bodies and wireless relay equipment, wherein the plurality of monitoring box bodies are in communication connection, display warning equipment and gas inlets are arranged on the monitoring box bodies, a shock insulation layer is arranged in each monitoring box body, and monitoring equipment and second monitoring equipment which are same in structure are arranged in the shock insulation layer. The monitoring methodcomprises the steps of supplying power by a power supply, and detecting a hazardous gas constituent in air by a gas detection sensor; and transmitting detection data of the gas detection sensor to anMCU controller after processing of a filter and a photoelectric converter. By the early-warning system and the monitoring method, the problems that the hazardous gas monitoring method lags behind andthe monitoring device is easily damaged in the prior art can be solved, and the early-warning system and the monitoring method are wide in application range, accurate and efficient in monitoring and high in design reliability.

Description

technical field [0001] The invention relates to the technical field of tunnel gas monitoring, in particular to a tunnel gas monitoring record and early warning system and a monitoring method thereof. Background technique [0002] With the rapid development of our country's economy, the construction of public transportation infrastructure has also developed rapidly, such as the construction of roads and railways. In the process, tunnels have been widely used as an efficient way to traverse mountains. However, due to my country's vast territory and complex environment, many formations contain some toxic and harmful gases, such as methane and hydrogen sulfide. [0003] At present, geological prospecting technology cannot accurately predict the occurrence of toxic and harmful gases. Therefore, during the construction process of the tunnel, toxic and harmful gases may escape or surge. Since the tunnel is a semi-enclosed space, the air circulation is not smooth, and if the toxic...
