Abstract

The invention relates to the wireless communication technology, more particularly to an inductive communication method used in a tunnel of a coal mine. Therefore, problems of short communication distance and high equipment cost of the present wireless communication technology in the coal mine can be solved. The inductive communication method comprises the following steps that: a transceiver at one end of a communication system or transceivers at two ends of the communication system is / are coupled with metal conductors that are laid in a tunnel of a coal mine, wherein the metal conductors include a power cable, a metal water pipe and an air hose; on the basis of a waveguide effect of metal conductors, communication is established between the transceivers at the two ends of the communication system by utilizing the metal conductors laid in the tunnel of the coal mine as transmission mediums, so that radio waves between the transceivers at the two ends of the communication system are transmitted along the surfaces of the metal conductors that are laid in the tunnel of the coal mine. According to the invention, the problems of short communication distance and high equipment cost of the present wireless communication technology in the coal mine can be effectively solved; and therefore, the inductive communication method is suitable for communication in the coal mine.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to an inductive communication method in a coal mine roadway. Background technique [0002] Communication technology is crucial to modern coal mine production safety and improving work efficiency. At present, wireless communication equipment has been widely used in coal mining enterprises and is still developing rapidly, such as underground wireless voice communication, underground personnel positioning system, etc. Due to the strong absorption and shielding effect of the strata on radio waves, the conventional wireless communication technology that has been maturely applied on the ground has greatly shortened the communication distance in the narrow space of the underground roadway, and the communication distance cannot be increased simply by increasing the transmission power . Therefore, prolonging the communication distance of wireless communication in the underground roadway...
