The present invention is achieved by the following technical solutions:A kind of mine inspection system based on leaky feeder communication, its feature It is, including signal/communication base station, base station power supply, leaky cable, PLC control cabinet, bidirectional relay, end load, hand Machine, latch buttons are held, the signal/communication base station is connected with base station power supply, and the signal/communication base station is by sewing Cable is connected with bidirectional relay, and the bidirectional relay is connected to end load, the signal/communication base by leaky cable Platform is connected with PLC control cabinet, and the latch buttons are in the control loop of signal/communication base station and PLC control cabinet, institute Hand-held set is stated by PLC with latch buttons control to be connected.
As one of preferred embodiment of the present invention, in addition to loudspeaker, the loudspeaker by speaker interface and signal/ The base station that communicates is connected.
One of preferred embodiment as the present invention, the PLC control cabinet includes list tank signal PLC and double tank signal PLC, institute Latch buttons are stated for two difference parallel connections and are connected respectively with single tank signal PLC with double tank signal PLC.
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.
One of preferred embodiment as the present invention, when mine inspection, the switch of the latch buttons is constantly in disconnection State.
The advantage of the present invention compared with prior art is:Present invention, avoiding the string during original wireless interspeaker use 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 Existing site operation personnel directly participate in the transmission with control signal, as long as workmen is not by the jerk lock release of hand-held set, No matter under any circumstance, not signal cabin operating desk will show signal jerk always, so when maintainer is in maintenance, Malfunction car occurs, is that basis has been tamped in the safety in production of mine so as to ensure that the safety of site operation personnel.The locking is protected Protective function is just as one " portable signal scram button ", and revolutionizing conventional on-site personnel actively can not promptly stop The scene of car, is that the safety during upkeep operation with the addition of a safety lock.
The concrete principle and installation steps of the present invention:A base station power supply (220V) is taken in auxiliary shaft list tank signal cabin, together When one signal/communication base station is installed, respectively lay a leaky cable to single tank in sheave wheel platform and shaft bottom and get room ready, be used as day Wheel and the transmission circuit of lower hole top signal contact.Simultaneously in order to ensure the safety during use, we are in single double tank operating desks On install a locking knob additional, it is in parallel after be serially connected in base station respectively into the jerk control loop of PLC control cabinet, so make Before the control for carrying out signal with base station, it is necessary to carry out the selection of locking knob, base station then could be realized to Dan Shuan The independent control of tank signal and hand-held set do not participate in the selection of the jerk control mode of signal directly during signal contact, from And ensure that the safety during use.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention Any modifications, equivalent substitutions and improvements made within refreshing and principle etc., should be included in the scope of the protection.
