Gas remote monitoring and alarming method, system and device in tunnel construction process and computer readable storage medium

Abstract

The invention relates to a gas remote monitoring and alarming method, system and device in the tunnel construction process and a computer readable storage medium, and belongs to the technical field of communication. The method comprises the following steps: respectively comparing the current gas concentration collected by each monitoring point with a preset concentration threshold value; judging whether the current gas concentration of each monitoring point is greater than or equal to a preset concentration threshold value, if so, acquiring position information of the monitoring point, and sending a first alarm signal according to the position information of the monitoring point; and if not, calculating a concentration difference value between the current gas concentration of the monitoring point and a preset concentration threshold value, determining a corresponding preset sampling frequency according to the concentration difference value based on a preset mapping table, and updating the current sampling frequency corresponding to the monitoring point to the preset sampling frequency, wherein the preset mapping table comprises corresponding relations between multiple groups of concentration difference value intervals and preset sampling frequencies. The method has the effect of improving the adaptability.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, system, device and computer-readable storage medium for gas remote monitoring and alarming during tunnel construction. Background technique [0002] With the continuous increase of tunnel construction in coal-measure strata in my country, the occurrence frequency of gas disasters is also increasing. Among them, gas explosions are the most common and most harmful. Therefore, real-time and accurate monitoring of the gas concentration in the tunnel is an important measure to ensure the personal safety of construction personnel and ensure the progress of construction. [0003] At present, common gas monitoring methods mainly include on-site manual monitoring and remote monitoring using gas monitoring systems. On-site manual monitoring requires staff to carry testing equipment to inspect various monitoring points in the tunnel, which cannot guarantee comprehensive an...

AI Technical Summary

Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that in the actual monitoring process, due to the large number of monitoring points in the tunnel, the gas concentration of different monitoring points is not the same. When all monitoring points are sampled at the same sampling frequency, It is not convenient to meet the sampling requirements of monitoring points with different gas concentrations, resulting in the untimely acquisition of concentration information of some monitoring points or waste of system resources at some monitoring points, which reduces the applicability of the gas monitoring system
