Sensor network based underground safety monitoring system, apparatus and method

Abstract

The invention relates to mine safety inspecting and wireless communication field, is a underground safety inspecting system based on sensor network and its device, techniques. The system includes ground monitor station, tunnel base station, wireless nodes. The systems techs include ground station techniques, tunnel station techniques, wireless nodes techniques. The ground monitoring station is for the communication between main computer and sensor network. The tunnel station has got sensors collecting data such as gas, carbon oxide, carbon dioxide, wind speed and transmitting the collected data together with personnel data to ground main control center by wireless and wired method. The system is competence to mine underground environment monitor, personnel locating and tracking, voice transmission, facilitating mine managing and scheduling, safety inspecting especially rescue of accidents.

Description

technical field [0001] The invention relates to the field of mine and functional underground safety monitoring and wireless communication, in particular to a sensor network-based underground safety monitoring system, device and method. Background technique [0002] At present, safety work in coal mines is one of the most important tasks in the process of coal mining. The production conditions of coal mines are very harsh, and major accidents are basically gas explosions and gas outbursts. , carbon monoxide, carbon dioxide and other harmful gases as well as parameters such as temperature, wind speed, start and stop status of key equipment are monitored. For high-gas mines, mine safety monitoring equipment must be installed. For mines that are not equipped with mine safety monitoring systems, the coal roadways, half-coal rock roadways, and the excavation face of rock roadways with gas gushing, and the excavation of rock roadways without gas gushing The working face and the co...

AI Technical Summary

Problems solved by technology

After the accident, the rescue work is easily affected by the collapse of the roadway, and it is difficult to find the trapped mine workers in time

At the same time, due to the high mobility of mine workers underground, it is difficult to determine the specific location and number of personnel in time. Once an accident occurs, it is difficult to carry out rescue work in time, thus delaying the rescue work and greatly increasing the risk factor of mine workers.

[0003] The main problems existing in my country's mine communication at present: one is the lack of a reliable mobile communication system with wide coverage

Second, the degree of networking and integration of the communication system is not enough

Third, the ability to resist disasters and accidents is poor

At present, the communication system is mainly wired. Once a disaster occurs, the line is easily damaged, resulting in communication interruption; in the case of damage to the induction transmission line, the intermediate frequency induction communication is not completely cut off like the wired communication, but its communication distance is also short. It is greatly affected, and the requirement of mine communication is precisely that the more severe disasters occur, the more it is necessary to ensure the smooth flow of safety and disaster relief communications
