Embodiment
Embodiment of the present utility model is elaborated below, the present embodiment using technical solutions of the utility model before
Put and implemented, give detailed embodiment and specific operating process, but the scope of protection of the utility model is unlimited
In following embodiments.
Referring to Fig. 1：A kind of mine inspection system based on leaky feeder communication, it is characterised in that including signal/communication base
Platform, base station power supply, leaky cable, PLC control cabinet, bidirectional relay, end load, hand-held set, latch buttons, the letter
Number/communication base station be connected with base station power supply, the signal/communication base station passes through leaky cable and bidirectional relay phase
Even, the bidirectional relay is connected to end load, the signal/communication base station and PLC control cabinet phase by leaky cable
Even, the latch buttons in the control loop of signal/communication base station and PLC control cabinet, by PLC controlled by the hand-held set
Device processed is connected with latch buttons control, in addition to loudspeaker, the loudspeaker pass through speaker interface and signal/communication base station
It is connected, by leakage cable transmission signal, improves the stability that signal transmits, and the latch buttons of hand-held set are maintenance people
Safety guarantee is provided during the maintenance of member, it is therefore prevented that unexpected to occur.
Referring to Fig. 2：The PLC control cabinet includes single tank signal PLC and double tank signal PLC, and the latch buttons are two
In parallel respectively and be connected respectively with single tank signal PLC with double tank signal PLC, respectively different maintenance parts provides safety guarantor
Barrier.
