Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model comprises explosion-proof casing 1, supply module and switch mainboard, it is inner that switch mainboard and supply module are arranged on explosion-proof casing 1, described switch mainboard comprises exchanger chip, two photoelectric conversion modules, network interface isolation module, indicating lamp module, electricity mouth module, light mouth A, light mouth B and light mouth C, electricity mouth module is connected with serial server, light signal passes into photoelectric conversion module from any one light mouth and passes to exchanger chip, and spread out of by electric mouth module or gone out by another two light oral instructions after photoelectric conversion module, the network telecommunication number spread out of by electric mouth module can be converted to RS-485 communication signal and transmit after serial server process, also can directly transmit, network telecommunication number passes into network interface isolation module from electric mouth module and passes to exchanger chip, and is gone out by any one light oral instructions after photoelectric conversion module, the index signal of indicating lamp module display exchanger chip, described supply module comprises isolating switch, transformer, Switching Power Supply, charge-discharge circuit plate and battery pack, mining alternating current is successively through isolating switch, transformer, Switching Power Supply and charge-discharge circuit plate, Switching Power Supply is that serial server is powered, and the modules that charge-discharge circuit plate is respectively on battery pack and switch mainboard is powered.
Further, described housing is provided with explosion-proof observation window 2; Increase explosion-proof observation window 2 to be convenient to staff and to carry out real time inspection to the situation of switch inside.
Further, described electric mouth module is made up of 16 electric mouths; Multiple electric mouth is adopted to increase the equipment be connected into, easy to use.
Mining ethernet communication system as shown in Figure 4, three light mouths of the present utility model, wherein two light mouths are used as to form gigabit trunk optical fiber redundant looped network, another light mouth then can be used to connect 100,000,000 other redundant optical fiber looped network or tree type networks, or be used for connecting subordinate's switch, or the automatically-monitored subset of working face is directly connected as subordinate's switch, crossheading flame proof computer, crossheading controller, unit switch and coal-winning machine Programmable Logic Controller in figure, the subordinate's switch whether connecting transition is determined by the distance condition of reality.
