Embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in Figure 1, the novel shield door insulating monitoring early warning system in the present embodiment, includes insulation tester 1 and monitoring unit.
Wherein the two ends of insulation tester 1 are connected on the surface of contact of insulating part 2 and shield door and platform slab, and this insulation tester 1 can detect the insulation resistance of insulating part 2 in real time, thus form failure of insulation alerting signal according to the size of insulation resistance.In the present embodiment, the insulation resistance safety value of insulating part 2 is 0.5M Ω, when insulating part 2 is under normal circumstances, the insulating resistance value that insulation tester 1 detects the insulating part 2 obtained should be more than or equal to 0.5M Ω, when the insulating resistance value that insulation tester 1 detects the insulating part 2 obtained is less than 0.5M Ω, then export failure of insulation alerting signal.The internal detection circuitry of insulation tester 1 as shown in Figure 2.
Monitoring unit includes gating module 31, centre panel 32, distant place warning dish 34 and host computer 33.
Wherein gating module 31 is connected with insulation tester 1, ARM chip in this gating module 31 may be used for receiving and processes the detection data of insulation tester 1, also there is in this gating module 31 the CAN communication chip 311 for transmitting failure of insulation alerting signal, namely the ARM chip in gating module 31, after receiving the failure of insulation alerting signal of insulation tester 1, controls CAN communication chip 311 and failure of insulation alerting signal is outwards transmitted.The internal circuit of gating module 31 is concrete as shown in Figure 3.
Centre panel 32 is connected with gating module 31 communication, there is in centre panel 32 main supervisory panel and RJ45 communication interface 321, main supervisory panel receives the failure of insulation alerting signal that gating module 31 transmits, and then control RJ45 communication interface 321 outwards transmits failure of insulation alerting signal.The internal circuit of centre panel 32 is concrete as shown in Figure 4.
Host computer 33 is connected with centre panel 32 communication, for monitoring the working condition of shield door, can check that the entirety of Rail Transit System controls situation in addition by host computer 33.Host computer 33 can record and point out failure of insulation alerting signal simultaneously.The internal circuit of host computer 33 is concrete as shown in Figure 5.
Distant place warning dish 34 is connected with centre panel 32 communication, and this distant place warning dish 34 can be used for realizing realizing insulation alarm to insulating part 2 in monitoring booth.
Alarm unit is provided with in host computer 33 and distant place console panel, this alarm unit can select display, voice guard, visual alarm and/or audible-visual annunciator etc. as required, in the present embodiment, alarm unit includes display and audible-visual annunciator simultaneously.Host computer 33 like this and distant place console panel then by display display, light flash, send chimes of doom three kinds of modes and report to the police simultaneously.
The course of work of this novel shield door insulating monitoring early warning system is: when insulating part 2 is normal, the warning of shield door insulating monitoring early warning system is not triggered, after insulating part 2 is by environment " pollution ", when the insulation resistance of the insulating part 2 that insulation tester 1 detects is less than the insulation resistance safety value of insulating part 2, then insulation tester 1 can send failure of insulation alerting signal to gating module 31, thus trigger the transmission that gating module 31 carries out alerting signal, gating module 31 passes through its CAN communication chip 311 by failure of insulation alerting signal to centre panel 32, after centre panel 32 receives failure of insulation alerting signal, by its RJ45 communication interface 321, this failure of insulation alerting signal is passed to host computer 33 and distant place warning dish 34, by host computer 33 and warning dish, this failure of insulation situation is reported to the police.Thus can notify that staff safeguards the insulating part 2 on shield door in time, also can reminding passengers in time, thus ensure the safety by bus of passenger.
