Under-mine voice communication system, device and method based on sensor network

Abstract

This invention relates to a mobile communication system, device and method for underground persons based on a wireless sensor network. Said system is composed of mobile nexuses supporting phonetic communication, gateways, a wire network and a managing center. The method includes: a method for mobile nexus with phonetic communication set in the cap-lamp communicating with the ground network center by the gateway, a communication method among mobile nexuses, which can be widely used in the phonetic communications among under ground working staff, daily dispatch and information exchange.

Description

technical field [0001] The invention relates to the field of underground communication in mines, in particular to an underground voice communication system, device and method based on a sensor network. Background technique [0002] For many years, the underground working environment of the mine has a complex geological environment, various harmful gases, and unknown water bodies escaping. With the advancement of science and technology, various detection systems, monitoring systems and communication systems have been deployed. However, vicious accidents in mines still continue to occur, seriously threatening the safety of underground workers. However, the mobility of underground operators is high and the working environment is complex. Once an accident occurs, the emergency communication of underground personnel is difficult to carry out, which brings great difficulties to the rescue work, often delays the best time for rescue, and causes serious consequences. If each unde...

AI Technical Summary

Problems solved by technology

Carrier telephones for overhead electric locomotives can facilitate communication between locomotive drivers to a certain extent, but because overhead rails are not a good carrier transmission channel, although there are many products so far, the communication quality is not ideal, and they are only suitable for locomotives few, close

[0004] 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
