Detailed description of the invention

The utility model is described in further detail with reference to the accompanying drawings and examples.

Fig. 1 is a kind of structural schematic diagram of the utility model.

Specific embodiment

Below in conjunction with attached drawing, the utility model is described in further detail.

A kind of intelligent double loop is mutually for electric machine control system, referring to Fig.1, including secondary control module 1, display control mould Block 2, electric node manometer control module 5, long-range rigid line control module 6, fire-fighting DC24V control module 7, major loop contactor 8, Back-up circuit contactor 9, signal feedback module 4 and standby motor fault-signal 3, in which:

The secondary control module 1 receive and process electric node manometer control module 5, long-range rigid line control module 6, Fire-fighting DC24V control module 7 passes through data line by respective control signal, the display control module 2 that data line passes over The manual start-stop control signal and standby motor fault-signal 3 that transmission comes, and can according to the hand that display control module 2 is arranged, Automated manner classifies above-mentioned various control modes are as follows: the control of display control module 2 is effective under manual mode, electrical nodes Pressure module of meter control 5, long-range rigid line control module 6, fire-fighting DC24V control module 7 each control signal be hand, automatic mode Lower effective, under manual mode, display control module 2 is by pressing the primary motor start and stop of key control, when primary motor cannot be opened normally When dynamic, primary motor failure signal 3 is transmitted to secondary control module 1, after being handled, can automatically switch, connect back-up circuit 9 coil of tentaculum is attracted, and is started spare motor, while state of a control is transmitted to display control module 2 by data, is issued report Alert, in alarm procedure, secondary control module 1 monitors primary motor in real time, if it restores normal, 9 line of back-up circuit contactor Power loss is enclosed, 8 coil of major loop contactor is attracted, automatically switches to primary motor and eliminate alarm.When two motors cannot be just Often when starting, standby motor fault-signal 3 is transmitted to secondary control module 1, and through handling, operating parameter is transmitted by data line It to display control module 2, indicates " halted state ", and issues alarm.In alarm procedure, two motors are monitored in real time, if main Restore normal with motor, then 8 coil of major loop contactor is attracted, and automatically switches to primary motor, and eliminate alarm；If standby electricity Machine restores normal, but primary motor still failure, then 9 coil of back-up circuit contactor is attracted, and starts spare motor, display control Module 2 issues alarm.Under automatic mode, secondary control module 1 according to electric node manometer control module 5 transmit come parameter intelligence It can choose whether starting motor and start primary motor when pressure is low, when pressure is high, stop primary motor.Fire fighting state Under, long-range rigid line control module 6, fire-fighting DC24V control module 7 control signal be transmitted to 1 the corresponding interface of secondary control module, Respective handling is made for it.The secondary control module 1 can be believed automatically hand by 4 output contact of signal feedback module Number, the feedback outputs such as run signal, fault-signal, electrical nodes pressure signal to backstage, realize that backstage monitors in real time.
