Description

A kind of visible light communication system for underground coal mine

Technical field

This utility model relates to visible light communication field, and a kind of visible ray for underground coal mine leads to Communication system.

Background technology

Along with improving constantly of coal production up-to-dateness, to means of communication, systemic-function requirement not Disconnected increase, the most constantly improve the communication system of underground coal mine, it is achieved quickly, in time, information accurately During transmission the most necessary, the Mine Communication system of present stage is mainly by wireline communication network and channel radio Communication network is constituted, and owing to tunnel structure is complicated, finite element network is not suitable for realizing, and current radio communication System is severe and mobile changeable due to environment on coalface, it is impossible to be suitable for the communication environment of coal mine work area.

Utility model content

The purpose of this utility model is to provide a kind of visible light communication system for underground coal mine, to solve The problem certainly proposed in above-mentioned background technology.

For achieving the above object, this utility model provides following technical scheme: a kind of for underground coal mine Visible light communication system, including management station, described management station is connected by electric conductor work station, server Group and optical fiber, described work station by electric conductor connect have Ethernet switch, described Ethernet switch by Electric conductor connects commercial hub and power bridge device, and described commercial hub is connected by electric conductor net Network video monitor, and power bridge device by electric conductor connect have PLC coupling transformer, described PLC coupling Close transformator to be connected by electric conductor and have a visible light receiver, and visible light receiver includes being sequentially connected electrically Illuminance transducer, single-chip microcomputer, IPD and optical signal transmitter, described visible light receiver is connected by electric conductor Have the power modulation that receptor, described receptor include being sequentially connected electrically reconcile module, light detection module, Pre-amplifying module, main amplification module, balance module, judging module, ARM micro-control module, power amplifier drive Dynamic model block and sound receiver module, described smooth detection module is also electrically connected with bias control module.

Preferably, the inside of described commercial hub is provided with firedamp sensor.

Preferably, the quantity of described power modulation actuator is at least 1.

Compared with prior art, the beneficial effects of the utility model: a kind of visible for underground coal mine Optical communication system, by the transmission work of management station, can effectively control the work of mobile device, reach To the normal use of visible light receiver, small and exquisite by visible light receiver is easy to carry, can be with workman Communication in severe and mobile changeable environment.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment Scheme is clearly and completely described, it is clear that described embodiment is only this utility model one Divide embodiment rather than whole embodiments.Based on the embodiment in this utility model, this area is common The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into this The scope of utility model protection.

Referring to Fig. 1-3, this utility model provides a kind of technical scheme: a kind of visible for underground coal mine Optical communication system, including management station 1, described management station 1 is connected by electric conductor work station 11, service Device group 12 and optical fiber 13, described work station 11 is connected by electric conductor an Ethernet switch 2, described with Too network switch 2 is connected by electric conductor commercial hub 21 and power bridge device 23, described commercial line concentration Device 21 is connected by electric conductor Network Video Surveillance device 22, and power bridge device 23 is had by electric conductor connection PLC coupling transformer 24, described PLC coupling transformer 24 is connected by electric conductor visible light receiver 3, And visible light receiver 3 includes the illuminance transducer, single-chip microcomputer, IPD and the optical signal launch that are sequentially connected electrically Device, described visible light receiver 3 is connected by electric conductor has receptor 4, described receptor 4 to include electricity successively The power modulation connected reconciles module, light detection module, pre-amplifying module, main amplification module, equilibrium Module, judging module, ARM micro-control module, power amplifier drive module and sound receiver module, and described light is examined Survey module and be also electrically connected with bias control module, by the transmission work of management station 1, can effectively control The work of mobile device processed, reaches the normal use of visible light receiver 3, and this utility model is small and exquisite to be easy to Carry, can be with workman's communication in severe and mobile changeable environment.

Operation principle of the present utility model: management station 1 issues synchronizing information and descending by visible light channel Early warning information is to visible light receiver 3；After visible light receiver 3 receives synchronizing information, by electric power bridge Connect device 23 and upload location information with up warning information to visible light receiver 3, it is seen that optical receiver 3 connects After receiving and processing upstream data, relevant information is transmitted to server group 12 by timing by power bridge device 23, Work station 11 is submitted to, by the optical signal of receptor 4 after data parsing being processed by server group 12 again The function of conversion, is delivered to optical signal the staff of down-hole, and management software is analyzed place to data The coal mine down-hole personnel communication information is presented on Network Video Surveillance device 22 by reason.
