Platform and because transmission range is not enough and caused by signal contact it is unclear, substantially increase the accuracy and security of signal contact.This
Invention can realize that site operation personnel directly participate in and control letter using the jerk blocking function of working drawing review personnel's hand-held set
Number transmission, be that basis has been tamped in the safety in production of mine so as to ensure that the safety of site operation personnel.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention;
Fig. 2 is latch buttons connection diagram of the present invention.
Embodiment
Embodiments of the invention are elaborated below, the present embodiment is carried out lower premised on technical solution of the present invention
Implement, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to following implementations
Example.
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 are in the control loop of signal/communication base station and PLC control cabinet, and the hand-held set is controlled by PLC
Device processed is connected with latch buttons control, in addition to loudspeaker, and the loudspeaker passes through speaker interface and signal/communication base station
It is connected, by leakage cable transmission signal, improves the stability of signal transmission, 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 list tank signal PLC and double tank signal PLC, and the latch buttons are two
Difference is in parallel and is connected respectively with single tank signal PLC with double tank signal PLC, and respectively different maintenance parts provides safety guarantor
Barrier.
One of preferred embodiment as the present invention, single tank signal PLC and double tank signal PLC are located at single double tank operating desks
On.
One of preferred embodiment as the present invention, the base station power supply can input AC127V/220V twin voltages.
One of preferred embodiment as the present invention, the exportable+12V/+18V twin voltages of base station power supply.
One of preferred embodiment as the present invention, the hand-held set is only located in mine inspection personnel's hand, is further improved
The security of maintainer.
One of preferred embodiment as the present invention, when mine inspection, the switch of the latch buttons is constantly in disconnection
State, it is therefore prevented that unexpected to occur.
Present invention, avoiding getting two or more radio stations at once during original wireless interspeaker use and because transmission range is not enough and caused by signal
Contact it is unclear, substantially increase the accuracy and security of signal contact.Utilize the jerk blocking function of hand-held set, Neng Goushi
