Mine environment probing and search and rescue emergency response system based on wireless sensor network

Abstract

The invention relates to a mine environment probing and search and rescue emergency response system based on a wireless sensor network, which comprises various intelligent wireless sensor network nodes, a plurality of backbone routing nodes of an underground wireless network, an underground wireless sensor network gateway, a fiber optic modem, an attendance reader, an IP network switch, a network server, a database center and a monitoring center, and has environment monitoring function before occurrence of accidents, positioning and tracking function in mine operation, electronic attendance function on operating miners, dynamic network repair function after the occurrence of the accidents, wireless voice calling function between ground and underground, and video monitoring and search and rescue function. The system can improve mine safety production management level, promote mine information construction, reduce occurrence of coalmine accidents, quicken the search and rescue process in mine disasters and the like, provides important information platform and has great application value.

Description

technical field [0001] The invention relates to the application fields of safety production in underground coal mines and emergency search and rescue of mine disasters, in particular to a mine environment detection and search and rescue emergency response system based on a wireless sensor network. Background technique [0002] At present, my country is the world's largest coal-producing country with abundant coal resources. Due to poor natural conditions of mines in my country, backward production technology, frequent disasters and accidents, heavy casualties. At present, the death toll of coal mine accidents in my country accounts for about 80% of the total number of mine accidents in the world, and the death rate per million tons is 100 times that of the United States and 30 times that of South Africa. At present, my country's coal mine safety situation is still very severe, which has attracted great attention from the country. Solving various potential safety hazards an...

Problems solved by technology

[0011] To sum up, for the research on coal mine environment detection and search and rescue, personnel positioning and tracking, some products have been prototyped and some patents have been authorized at home and abroad. However, the frequent occurrence of coal mine accidents in recent years has proved that there are already The research results of this paper have only solved part of the problems, and there are still many problems, which are specifically reflected in: (1) the technical means selected by the existing products are relatively backward; There is no effective overall solution; (3) The real-time response of the system is not enough

(4) Research on some issues needs to be further deepened and developed, such as insufficient accuracy of personnel positioning, poor reliability of underground networks, etc.
