Description
Technical field
The present invention relates to the safety return circuit of subway shield door, particularly relate to the diagnosis of safety return circuit, position fixing system.
Background technology
Subway is effective measures of solving urban traffic blocking, and subway also has advantages such as reducing noise jamming, economize energy, decreasing pollution.Subway shield door is the visual plant of modern city subway construction, most employing screen door in the new subway circuit of national each big city.Subway shield door is the high-tech product integrating the subjects such as building, machinery, material, electronics and information, primarily of compositions such as door body structure, power-supply system, drive system, control system, network systems.
Safety return circuit, as the core component of screen door control system, directly affects the stability of screen door operation, safety.Each door apparatus is equipped with safety return circuit, the safety return circuit series connection of all shielded gates.When all shielded gates of platform are closed completely and lock, all sliding doors and corresponding emergency door are closed detector switch and all sliding door electromagnetic locks and are locked detector switch and connect, 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 connecting cannot conducting, signal system can't detect screen door safety signal, now, the train stopped cannot send, and is about to the train then urgent stop entered the station.
Existing safety return circuit is cascaded, although good safety precaution can be accomplished, but cannot quick position to go out be the outlet problem of which shielded gate, the off position of safety return circuit cannot be judged, therefore, how to provide a kind of can quick position to go out the diagnostic system of the trouble point of safety return circuit and diagnostic method be industry technical matters urgently to be resolved hurrily.
Summary of the invention
The present invention is in order to solve the technical matters existed in above-mentioned prior art, propose a kind of shielded gate fault location system, comprise main monitoring and control centre, the each door machine controller be connected with main monitoring and control centre respectively, the shielded gate K switch 1 controlled by each door machine controller, 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 closes, 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 uploaded to main monitoring and control centre by described door machine controller.
The present invention can monitor in real time to the safety return circuit of each shielded gate, once safety return circuit et out of order, can navigate to trouble point rapidly, and carry out on-call maintenance, guarantee the safety of metro operation.
Accompanying drawing explanation
Fig. 1 is fundamental diagram of the present invention;
Fig. 2 is diagnostic circuit figure of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1 to Figure 2, the shielded gate fault location system that one embodiment of the invention 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 machine controller controls a pair shielded gate, namely a pair shielded gate K switch 1 is controlled, K2, mutually connect between each shielded gate K switch 1, mutually connect 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, diagnostic circuit is to the monitoring state of safety return circuit, and send main monitoring and control centre to by treater, such as, when shielded gate is closed, each shielded gate K switch 1, K2 closes, 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 uploaded to main monitoring and control centre by described door machine controller, the corresponding information of each shielded gate and the state of safety return circuit can be had a clear understanding of like this on the giant-screen of main monitoring and control centre, once there be shielded gate et out of order, just know and know which shielded gate goes wrong, can staff be sent immediately to rush to repair.
Diagnostic circuit comprises: resistance R1, R2, R3, coupler U1, shielded gate K switch 1, K2 connect two input ends of coupler U1 respectively, resistance R3 is connected between coupler U1 and shielded gate K switch 1, the two ends of resistance R2 connect two input ends of coupler U1 respectively, the collecting electrode of resistance R1 mono-termination coupler U1, another termination power end, the collecting electrode of described coupler U1 meets 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 the non-conducting of coupler U1, the voltage of the treater port I1 of door machine controller is higher, but, when shielded gate is closed, namely shielded gate K switch 1, after K2 is closed, shielded gate K switch 1, 24V voltage between K2 is through resistance R2, R3 transfers light current to, input to the input end of coupler U1, through optocoupler, the voltage of treater port I1 is become 0, after signal received by treater, the state recording of safety return circuit is uploaded to main monitoring and control centre, main monitoring and control centre record correlation behavior, for the data analysis of safety return circuit state.
By this diagnostic circuit, door machine controller can the state of real time monitoring safety return circuit, 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 accurate fault point, or finds the potential fault of safety return circuit, is beneficial to and efficiently carries out handling labor.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
