Abstract

The invention relates to an optical fiber communication system which can detect a plurality of mining conveyor belts, comprising an underground control module, a no-source optical distributing network, a surface main controller and a control computer. The underground control module firstly multiplexes signals collected by a conveying belt sensor into high-speed optical signals and then sends signals to the surface main controller, and the surface main controller de-multiplexes signals into original sensor signals and then sends the signals to a signal processor. The surface main controller controls the sending of a plurality of underground control modules through lower data chancels to lead the plurality of underground control modules to share the optical fiber link. The optical fiber communication system makes use of the no-source optical fiber network to transmit the sensed signals of the plurality of conveying belts, thus displacing the underground signal processing system and highly enhancing the anti-interference capability and reliability of the system.

Description

technical field

[0001] An optical fiber communication system capable of monitoring a plurality of mine conveyor belts uses an optical passive distribution network as a signal transmission channel, and is used for an above-ground control computer to collect sensing signals of each underground conveyor belt. Background technique

[0002] The underground conveyor belt of a coal mine is the only transportation channel for mining raw coal. If the conveyor belt fails, the raw coal cannot be transported to the mine, which will stop production and cause economic losses. Therefore, grasp the operation status of the conveyor belt at any time, monitor the joints and broken ends of the conveyor belt, and find problems in time to avoid losses.

[0003] The initial conveyor belt monitoring was all done manually. The conveyor belt was irradiated with an X-ray machine to check the joints and broken ends of the steel wires in the conveyor belt, and then reported to the Inoue command center f...
