Embodiment

As shown in Figure 1: the utility model comprisesmonitor unit 3, controller, power supply 4,warning device 2,voltage transducer 5,current sensor 6,open circuit sensor 7,heat sensor 8, data/address bus 1, thefirst switch 10,second switch 11, the3rd switch 12, the4th switch 13, thefirst water pump 91, the second water pump 92, the 3rd water pump 93, the 4th water pump 94.Its middle controller andmonitor unit 3 are done as a whole being placed in 304 stainless steel casings, and convenient the use installed.

When this device work, the staff can observe each sensor to the detected working state of first to fourth water pump atmonitor unit 3, and can send instruction by controller and first to fourth water pump is enabled and be forbidden, dispose flexibly, and when each water pump breaks down, can in time startwarning device 2 and send alarm signal.

It below is the active configuration pattern that each water pump can arrange when work.To reach the purpose that is fitted to each other.

When the first water pump is configured to main pump, second and third, four water pumps will be the auxiliary standby water pump; When first and second water pump was configured to main pump, third and fourth water pump was the auxiliary standby water pump; When first, second and third water pump was configured to main pump, the 4th water pump was the auxiliary standby water pump.

We are configured to main water pump with thefirst water pump 91; the second water pump 92; the 3rd water pump 93; the pattern that the4th water pump 94 is configured to the auxiliary standby water pump is example; suppose that the process requirements reserve pump is enabled in 10 seconds and can meets the demands; the equipment redirect time is 5 seconds in device; when the first water pump breaks down in the running; the sensor that detects fault message sends trouble signal and is transferred to controller; controller issues instructions to the output terminal that links to each other with thefirst switch 10; thefirst switch 10 deenergizations; the firstmain pump 91 is shut down; controller is exported simultaneously a control signalcontrol warning device 2 and is sent alarm signal; after 5 seconds; controller sends jump instruction to the output terminal that links to each other withsecond switch 11, makessecond switch 11 pluggeds, and the second reserve pump 92 drops into automatically.This moment, the second water pump 92 was process pump; when the second water pump 92 breaks down again; controller issues instructions to the output terminal that links to each other withsecond switch 11; makesecond switch 11 deenergizations, the second water pump 92 is shut down, and controller is exported simultaneously a control signalcontrol warning device 2 and sent alarm signal; after 5 seconds; controller sends jump instruction to the output terminal that links to each other with the3rd switch 12, makes the 3 12 plugged, and the 3rd reserve pump 93 drops into automatically.This moment, the 3rd water pump 93 was process pump; when the 3rd water pump 93 breaks down again; controller issues instructions to the output terminal that links to each other with the3rd switch 12, makes the3rd switch 12 deenergizations, the 3rd water pump 93 hard stops; controller is exported simultaneously a control signalcontrol warning device 2 and is sent alarm signal; after 5 seconds, controller sends jump instruction to the output terminal that links to each other with the4th switch 13, makes the4th switch 13 pluggeds; the4th water pump 94 drops into again, and this redirect finishes.

In jump procedure, perhaps after a period of time, the pump that once broke down has been removed fault, and system can return to the front state of redirect so, if thefirst water pump 91 once was main pump, but because fault has jumped to 92 work of the second reserve pump, but after after a while, the fault of thefirst water pump 91 solves, and failure detection sensor no longer sends trouble signal, the second reserve pump 92 can stop so, the 91 automatic startup work of the first main water pump.

The utility model can be supported the redirect of working between 2 to 4 water pumps.

The realization of the utility model function is mainly by the working state that is distributed in each water pump of sensor Real-Time Monitoring on each water pump branch road, under-voltage as whether having, open circuit, open circuit, the fault such as overheated.After sensor detects above any fault, can give controller with the trouble signal transmission, controller is out of order according to monitoring and a little in time processes with fault message.The monitoring information that each sensor transmissions can also be come with Time Controller outputs on themonitor unit 3, and the staff can watch the working state of a water pump, the fault message when breaking down in real time.
