Abstract
The utility model discloses a screen door fault location system. The screen door fault location system comprises a main monitoring center, door machine controllers connected with the main monitoring center, a screen door switch K1 and a screen door switch K2, wherein the screen door switch K1 and the screen door switch K2 are controlled through the door machine controllers and connected in series to form a safety circuit. Each door machine controller is provided with a diagnosis circuit which is connected with the screen door switch K1 and the screen door switch K2. When the screen door switch K1 and the screen door switch K2 are switched on, the diagnosis circuits convert the 24V voltage between the screen door switch K1 and the screen door switch K2 into a weak current signal and transmits the weak current signal to processors of the door machine controllers. The door machine controllers upload the state of the safety circuit and information of door machines to the main monitoring center. The screen door fault location system can monitor metro operation in real time and position faults of a screen door, and therefore repair can be conducted in time.

Safety return circuit, as the core component of screen door control system, directly affects stability, the safety of screen door operation.Each door apparatus is equipped with safety return circuit, the safety return circuit series connection of all shielded gates.In the time that all shielded gates of platform are closed completely and lock, all sliding doors close detector switch with corresponding emergency door and all sliding door electromagnetic locks locking detector switch is connected, safety return circuit conducting.Now by screen door safety relay, safety return circuit connection signal is sent to signal system, signal system judges that screen door is in a safe condition, and subway train can enter the station safely or dispatch a car.Otherwise, do not close completely if any any one grade of sliding door or emergency door, corresponding detector switch open circuit, its safety return circuit disconnects, cause the safety return circuit of series connection cannot conducting, signal system can't detect screen door safety signal, now, the train having stopped cannot send, and the train that to be ready entering the station is urgent stop.
Existing safety return circuit is cascaded, although can accomplish good safety precaution, but cannot orient is fast the outlet problem of which shielded gate, cannot judge the off position of safety return circuit, therefore, how providing a kind of diagnostic system of the trouble point that can orient fast safety return circuit and diagnostic method is industry technical matters urgently to be resolved hurrily.
Summary of the invention
The utility model is in order to solve the technical matters existing in above-mentioned prior art, a kind of shielded gate fault location system has been proposed, comprise main monitoring and control centre, each the machine controller being connected with main monitoring and control centre respectively, by the shielded gate K switch 1 of each machine controller control, K2, described shielded gate K switch 1, K2 is mutual safety return circuit in series respectively, described door machine controller is provided with diagnostic circuit and shielded gate K switch 1, K2 is connected, when each shielded gate K switch 1, K2 closure, described diagnostic circuit is by shielded gate K switch 1, 24V voltage between K2 transfers weak electric signal to, and this weak electric signal is sent to the treater of a machine controller, the information of the state of safety return circuit and door machine is sent to main monitoring and control centre by described door machine controller.
The utility model can be monitored in real time to the safety return circuit of each shielded gate, once safety return circuit et out of order can navigate to rapidly trouble point, and carry out on-call maintenance, guarantees the safety of metro operation.
Brief description of the drawings
Fig. 1 is fundamental diagram of the present utility model;
Fig. 2 is diagnostic circuit figure of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1 to Figure 2, the shielded gate fault location system that the utility model one embodiment proposes, be provided with a main monitoring and control centre, this main monitoring and control centre is connected with the door machine controller of each shielded gate, each a pair of shielded gate of machine controller control, control a pair of shielded gate K switch 1, K2, series connection mutually between each shielded gate K switch 1, series connection mutually between each shielded gate K switch 2, the shielded gate K switch 1 of series connection, K2 forms the safety return circuit of shielded gate, door machine controller is provided with diagnostic circuit and shielded gate K switch 1, K2 is connected, the monitoring state of diagnostic circuit to safety return circuit, and send main monitoring and control centre to by treater, for example, when shielded gate is closed, each shielded gate K switch 1, K2 closure, described diagnostic circuit is by shielded gate K switch 1, 24V voltage between K2 transfers weak electric signal to, and this weak electric signal is sent to the treater of a machine controller, the information of the state of safety return circuit and door machine is sent to main monitoring and control centre by described door machine controller, on the giant-screen of main monitoring and control centre, can have a clear understanding of like this corresponding information of each shielded gate and the state of safety return circuit, once there be shielded gate et out of order, just know and know which shielded gate goes wrong, can send immediately staff to rush to repair.
Diagnostic circuit comprises: resistance R 1, R2, R3, coupler U1, shielded gate K switch 1, K2 connect respectively two input ends of coupler U1, resistance R 3 is connected between coupler U1 and shielded gate K switch 1, the two ends of resistance R 2 connect respectively two input ends of coupler U1, the collecting electrode of resistance R 1 one termination coupler U1, another termination power end, the collecting electrode of described coupler U1 connects the treater port I1 of a machine controller, the grounded emitter of coupler U1 again.
Coupler U1 Isolated Shield door switch K1, signal between K2, when coupler U1 is not when conducting, the voltage of the treater port I1 of door machine controller is higher, but, in the time that shielded gate is closed, namely shielded gate K switch 1, after K2 closure, shielded gate K switch 1, 24V voltage between K2 is through resistance R 2, R3 transfers light current to, input to the input end of coupler U1, through optocoupler, the voltage of treater port I1 is become to 0, treater is received after signal, the state recording of safety return circuit is uploaded to main monitoring and control centre, main monitoring and control centre records correlation behavior, for the data analysis of safety return circuit state.
By this diagnostic circuit, door machine controller can real time monitoring safety return circuit state, when after safety return circuit disconnection or flash, monitoring and controlling system can show the safety return circuit state of this shielded gate in time, find the off position of safety return circuit, repair and maintenance personnel can accurately locate trouble point, or find the potential fault of safety return circuit, are beneficial to and efficiently carry out handling labor.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
