Mine emergency communication and monitoring system

Abstract

The invention discloses a mine emergency communication and monitoring system. The mine emergency communication and monitoring system comprises wireless power supply devices, wireless node devices, monitoring devices, underground wireless terminal devices and the like; each wireless power supply device supplies power to each wireless node device; and when a disaster accident occurs in a mine, the wireless node devices composes an emergency wireless communication network so as to provide a communication service for the underground wireless terminal devices. The mine emergency communication and monitoring system can avoid aboveground-underground communication interruption which is caused by damage of communication and power supply cables when a disaster occurs, can provide reliable communication and positioning services for underground trapped persons and rescue workers after the underground disaster occurs, and can monitor underground site conditions.

Description

technical field [0001] The invention relates to a mine emergency communication and monitoring system, which relates to the fields of sensor technology, wireless communication technology, wireless charging technology and the like. Background technique [0002] Coal is the main energy in my country, accounting for about 70% of the primary energy. The coal industry is a high-risk industry, and accidents such as gas, flood, fire, roof, and coal dust have plagued coal mine safety production. The underground communication system is one of the "six major safety and risk avoidance systems" in coal mines, and it is an important guarantee for the safe production of coal mines. The existing underground communication system mainly includes a wired dispatching system, a mobile communication system, a broadcasting system, a disaster relief system, and a ground-penetrating communication system. When accidents such as gas outburst, gas explosion, rock burst, roof fall, flood, and fire occ...

AI Technical Summary

Problems solved by technology

When accidents such as gas outburst, gas explosion, rock burst, roof fall, flood, and fire occur underground, it will cause damage to various communication equipment, communication cables, power supply cables, and underground monitoring equipment in the underground roadway. Therefore, wired dispatching Systems, mobile communication systems, and broadcasting systems are vulnerable to disasters and accidents and cannot be used

Disaster relief communication system The wireless communication system carried by post-disaster rescue personnel can realize communication within a certain range after the disaster, but it is still unable to communicate in areas that rescue personnel cannot reach

The ground-penetrating communication system is a communication system based on low-frequency ground-penetrating communication technology. The impact of accidents is small and the disaster resistance is strong. However, the transmitting equipment and transmitting antenna of the ground-penetrating communication are large in size and high in cost. Therefore, the ground-penetrating communication generally adopts the one-way broadcast communication method. Downhole personnel can only receive information from the well, but cannot send information. Only a limited number of underground chambers can be equipped with transmitting equipment. After an accident, the wellside still cannot know the situation of the underground personnel and the situation on the spot that are not in the chamber, so the communication through the ground The system cannot meet the needs of mine emergency communication
