The utility model discloses a kind of DC control cabinet, comprise and be arranged on signal circuit assembly in cabinet and Siemens CUD1 electron plate, signal circuit assembly is provided with comprehensive light fault, comprehensively heavy fault, excitation and operating power, conjunction alternating-current switch closes, close alternating-current switch and point alternating-current switch signal output point; Comprehensive light fault, comprehensively heavy fault, excitation and operating power, conjunction alternating-current switch close, close alternating-current switch is connected programmable logic controller (PLC) with a point alternating-current switch signal output point, and programmable logic controller (PLC) is provided with outside light fault and resets, starts and stop control, enable control and long-range four output points of local & to be connected with Siemens CUD1 electron plate.This DC cabinet can simplify the connection of signal circuit assembly and direct current daughter board, reduces signal circuit assembly and is connected the probability of makeing mistakes with accidents happened between direct current daughter board.
Description
Technical field
The utility model relates to a kind of electrical control equipment, particularly a kind of DC control cabinet.
Background technology
Electrical control cabinet is mainly used in the high and low level control signal that reception liquid level controller (device) exports, and control automatically opening and stopping of pump motor, its control form has direct-on-line starting, the starting of step-down soft-start cabinet, soft start, variable frequency control etc.DC control cabinet belongs to the one of electrical control cabinet, existing electrical control cabinet is connected with the control panel on control cubicle by direct current daughter board, on the one hand multiple external input signal is changed into indicator light signal, by arranging indicator light display on the control panel, on the other hand, artificial input command is delivered in the signal circuit assembly in cabinet.Signal circuit assembly is directly connected with direct current daughter board, all external signals on signal circuit assembly are all be connected into direct current daughter board through auxiliary relay, the input point of direct current daughter board is increased, add the probability that accident occurs, make the connection of various holding wire in cabinet complicated simultaneously, easily wiring error phenomenon occurs.
Utility model content
The purpose of this utility model is to provide a kind of DC control cabinet, can simplify the connection of signal circuit assembly and direct current daughter board, reduces signal circuit assembly and is connected the probability of makeing mistakes with accidents happened between direct current daughter board.
For achieving the above object, the technical scheme that an embodiment of the present utility model is taked is:
Comprise and be arranged on signal circuit assembly in cabinet and Siemens CUD1 electron plate, signal circuit assembly is provided with comprehensive light fault, comprehensively heavy fault, excitation and operating power, conjunction alternating-current switch closes, close alternating-current switch and point alternating-current switch signal output point; Comprehensive light fault, comprehensively heavy fault, excitation and operating power, conjunction alternating-current switch close, close alternating-current switch is connected programmable logic controller (PLC) with a point alternating-current switch signal output point, and programmable logic controller (PLC) is provided with outside light fault and resets, starts and stop control, enable control and long-range four output points of local & to be connected with Siemens CUD1 electron plate.
Preferably, signal circuit assembly be also provided with debugging output point be connected with programmable logic controller (PLC).
Preferably, programmable logic controller (PLC) is S7-200 programmable logic controller (PLC).
The beneficial effect that this DC control cabinet produces is: by arranging programmable logic controller (PLC) between signal circuit assembly and direct current daughter board, all signals on signal circuit assembly are sent on direct current daughter board through programmable logic controller (PLC) again, decrease the input point of direct current daughter board, decrease the probability being connected between signal circuit assembly with direct current daughter board and makeing mistakes with accidents happened.
Accompanying drawing explanation
Figure 1 shows that the schematic diagram of the embodiment connected by programmable logic controller (PLC) between signal circuit assembly and direct current daughter board.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the utility model specific embodiment and corresponding accompanying drawing, technical solutions of the utility model are clearly and completely described.
With reference to figure 1, Figure 1 shows that the schematic diagram of the embodiment connected by programmable logic controller (PLC) between signal circuit assembly and direct current daughter board.In the present embodiment, DC control cabinet comprises and is arranged on signal circuit assembly 1 in cabinet and Siemens CUD1 electron plate 3, signal circuit assembly 1 is provided with comprehensive light fault, comprehensive heavy fault, excitation and operating power, close alternating-current switch to close, close alternating-current switch and point alternating-current switch signal output point, comprehensive light fault, comprehensive heavy fault, excitation and operating power, close alternating-current switch to close, close alternating-current switch and be connected programmable logic controller (PLC) 2 with a point alternating-current switch signal output point, programmable logic controller (PLC) 2 is provided with outside light fault and resets, start and stop controlling, enable control is connected with Siemens CUD1 electron plate 3 with long-range four output points of local &.In programmable logic controller (PLC) 2, by above-mentioned comprehensive light fault, comprehensive heavy fault carry out judgement do fault export and receive reset command carry out failure reset, when having a fault, programmable logic controller (PLC) 2 exports fault model, and on control panel, malfunction indicator lamp is bright, after troubleshooting, press failure reset button on control panel, programmable logic controller (PLC) 2 receives reset model, and open failure output signal during fault-free, on control panel, trouble light goes out.
By arranging programmable logic controller (PLC) 2 between signal circuit assembly 1 and Siemens CUD1 electron plate 3, all signals on signal circuit assembly 1 are sent on Siemens CUD1 electron plate 3 through programmable logic controller (PLC) 2 again, decrease the input point of Siemens CUD1 electron plate 3, decrease the probability being connected between signal circuit assembly 1 with Siemens CUD1 electron plate 3 and makeing mistakes with accidents happened.
In an embodiment of the present utility model, signal circuit assembly 1 is also provided with debugging output point and is connected with programmable logic controller (PLC) 2, when mistake appears in DC control cabinet, can carry out debugging and correct.
In an embodiment of the present utility model, programmable logic controller (PLC) is S7-200 programmable logic controller (PLC).
Above-mentioned execution mode is used for explaining and the utility model is described; instead of the utility model is limited; in the protection range of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection range of the present utility model.
