Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1; On the face of land host computer is set; At pump house the PLC Programmable Logic Controller is set, the communication terminal of PLC Programmable Logic Controller connects host computer, and the output terminal of PLC Programmable Logic Controller connects topworks; Topworks is provided with connection drainage equipment, and the input end of PLC Programmable Logic Controller is provided with and connects unwatering pump, electric gate valve, diversion case solenoid valve, current transducer, electro connecting pressure gauge and level sensor.Unwatering pump, electric gate valve, diversion case solenoid valve, current transducer, electro connecting pressure gauge and level sensor can be provided with many as required.The input end of PLC Programmable Logic Controller is provided with the connection microcomputer time controller.
The communication terminal of PLC Programmable Logic Controller is provided with fiber optical transceiver, connects host computer through optical cable.
The host computer of mentioning in the utility model and topworks are provided with that to be connected drainage equipment be common prior art, are provided with and are used for industry technician in fact and grasp.
Principle of work and use:
One cover PLC controller is installed in the pump house, is gathered pump house various kinds of equipment signal, by executive routine after the PLC logic determines, and image data is uploaded to the ground ipc monitor, the ground host computer also can be transferred data, realizes the communication contact of PLC and host computer.Concrete PLC Programmable Logic Controller adopts Siemens S7-226CN PLC, and expansion switch amount and analog module are according to realizing function elaboration practical implementation situation.
1. the upper limit on the water level
Prescribe a time limit when the 1# water bunker level reaches, the normal opened contact of 1# water bunker level instrument is closed; 1# water bunker level relay gets electric, the normal closure of making war, and PLC carries out upper limit program on the water level according to obtaining signal, and under this signal condition, all pump groups will start draining successively according to the time sequencing of setting in the pump house; Start 1# pump group, after the startup pump group, corresponding electric gate valve action, gate valve stops after reaching the position automatically.
2. the water level upper limit
Prescribe a time limit when the 1# water bunker level reaches, the normal opened contact of water bunker level instrument is closed, and relay gets electric, the normal closure of making war, and the PLC basis obtains signal and carries out water level upper limit program.The upper limit is compared on this process and the water level, and order does not open this link of pump.
3. diversion case water level
The prerequisite that starts the pump group is: first testing pump group diversion case water level, if the entry condition of not reaching, junction closure in the cistern water level instrument then, 1# diversion case level relay is closed, and PLC carries out diversion case moisturizing program, output according to obtaining signal.
4. pump group running protection
After the pump group starts, testing pump group top hole pressure and Electrically operated gate switch situation.If top hole pressure is lower than setting value, the 1#PCY contact of electro connecting pressure gauge is connected, the 1# electro connecting pressure gauge closure of often making war, and PLC judges that water pump do not go up water and automatically perform and stop pump group program.If Electrically operated gate is opened not in place or is failure to actuate then the 1#MKDW contact is disconnected, relay must not electricity, and the 1# electric gate valve is normal makes war not closedly, and PLC judges that electric gate valve is opened not in place or is failure to actuate to carry out and stops pump group program automatically.
Clock is input as a microcomputer time controller, is Pinggu, peak time period of the convenient input setting of field staff.
5. water level lower limit
In limited time, it is electric that the contact 1#SWX junction closure of water bunker level instrument, 1# water bunker level lower limit relay get under water level reaches, the normal closure of making war, and PLC judgement water level automatically performs to lower limit and stops pump group program.
6. the pump group stops
The pump group stops according to closing the order that electric gate valve stops unwatering pump more earlier.After electric gate valve closed and puts in place, PLC carried out according to electric gate valve valve-off signal and stops the unwatering pump program; After the pump group stops, PLC output, diversion case level relay gets electric, and PLC carries out diversion case moisturizing program.
7. emergency condition
In emergency circumstances, guard system does not operate on the spot still automatically, can make operating unwatering pump force to stop through local operation case " urgent termination of pumping " button, and close electric gate valve automatically.
8. analog signals
PLC analog module EM231 input terminal RA, A+, A-(RB, B+, B-, RC, C+, C-, RD, D+, D-) connect 4～20MA signal terminal of current transducer and water level transmitter respectively.
9. on the spot/automatically switch and transform
Retrofit work gets final product for increasing a switch CK, keeps original control system.
10. communication
PLC and ground upper machine communication adopt optical cable, utilize the typical PC-PPI communication modes of PLC, adopt fiber optical transceiver equipment realization PLC and ground host computer to get in touch.
