Failure causes operation at that time, can not send radio alarm signal from trend master controller computer；Master controller is pacified
Loaded on the practical operation situation that more PLC of understanding in master control room, can be monitored.
Case study on implementation
Device is mounted on rainwater conflux pipe in need, is realized and is changed pipeline rainwater flow direction, packet under desired specified conditions
It includes the removal of initial rainwater, clean the collection of rainwater and the discharge of excessive rainwater.
When one rainfall starts, the rainwater of hard surface enters rainwater conflux pipe by the collection confluence of inlet for stom water, flows through
The early-stage rainwater stream abandoning device being mounted on storm sewer.Flowmeter monitors flow information first, starts to start function of measuring,
The rainwater total amount information being recorded is passed into PLC, PLC receives flow signal, starts to start, by 1 operation of programming；At this time
Rainwater flows through four-way abandoned stream valve port, into sewage treatment plant；After a period of time, the rainwater flow that flowmeter monitors reaches initial stage
Rain water drainage amount, PLC are ordered according to programming 1 and are executed, move rotating wheel (1) to support rod (1) side, thus drive valve plate
(1) it rotates, closes abandoned stream valve port, opens and collect valve port, so that clean rainwater obtains Collection utilization later；If under prolonged
Rain makes excessive rainfall, cannot be further continued for being collected utilization, and PLC programming performs the next step suddenly, makes rotating wheel (2) to support rod
(2) side moves, and then valve plate (2) rotates, and closes and collects valve port, opens excessive valve port, makes extra rainwater through excessive valve port
It in time, is rapidly discharged into neighbouring irrigation canals and ditches, concave herbaceous field, rainwater valve port etc.；Operation programming 2 while operation programming 1,
, then cannot be again as being a rainfall i.e. when rainfall is too low and after a period of time, ground has been contaminated again, or drop
Rain terminates, and all needs automatic adjustment that flow abandoning apparatus reset is made to reenter original state, receives wherein valve plate (2) are first carried out and reset
Collect valve port unlatching and excessive valve port closing, rotating wheel (2) are standby, then is that valve plate (1) resets i.e. abandoned stream valve port unlatching, collection valve port
Closing, rotating wheel (1) are standby, and last flowmeter zero, standby, PLC is standby, the rain water drainage of a rainfall, collection, excessive row
Putting formally terminates.
