Wireless power transmission technology and its application in mine safety monitoring system

The paper introduced concept and development history of wireless power transmission technology, expounded three kinds of wireless power transmission modes of electromagnetic induction mode, radio waves and electromagnetic resonance mode according to existing wireless power transmission standards, and thought that the magnetic coupled resonant wireless power transmission mode is the most promising research area in the future. It analyzed application prospect of the wireless power transmission technology in coal mine according to characteristics of the coal mine working environment and explosion-proof requirements, and pointed out that the mine safety monitoring system is the priority development areas of wireless power transmission technology. It analyzed requirements and significance of application of the wireless power transmission technology in mine safety monitoring system by use of an example and according to Coal Mine Safety Regulation and relevant industry standards, put forward key problems which need to be solved of mine wireless power transmission technology.
