Abstract

The invention discloses a leaky cable communication system, which comprises a first system information source, a second system information source, a loop and a leaky cable, wherein the first system information source and the second system information source are connected with a centralized monitoring device; the centralized monitoring device respectively feeds mixing radio frequency signals and a power supply to a radio frequency input end and a power supply input end of the loop through a radio frequency cable and a power supply transmission line; an output end of the loop is connected with a plurality of explosive-proof multi-frequency bilateral amplifiers in series through the leaky cable so as to extend along the underground environment or a tunnel to achieve signal coverage; and in addition, a final explosive-proof multi-frequency bilateral amplifier is connected with a retransmission antenna.

Description

technical field [0001] The invention relates to communication transmission, in particular to a leaky cable communication system. Background technique [0002] At present, major cities are constructing subway projects, large-scale underground tunnel projects, and mining projects of various minerals. During the construction process, these environments are confined dangerous spaces, which can be safely constructed in these confined dangerous spaces and temporary after construction. Or the integrated application of permanent multi-system communication engineering is very important. Due to the complexity of network construction in these closed and dangerous environments, it brings great inconvenience to the construction of network signal coverage, centralized monitoring of communication equipment, and power supply. Contents of the invention [0003] Aiming at the shortcomings of the prior art, the object of the present invention is to provide a leaky cable communication system...
