Go out all water pump operations combination of the total flow value；
4）Logic judgment and output control value, according to step 3）Obtained a variety of water pump operations combination, it is total in data successively respectively
Searched in table and calculate the total energy consumption value of every kind of water pump operation combination；Logic judgment is carried out by logic judgment unit again, looked for
Go out a kind of minimum operation combination of total energy consumption, and export this kind of water pump operation and be incorporated into control unit；
5）Adjustment control, control unit meet step by controlling water pump start and stop or entering line frequency change water pump operation situation
4）The water pump operation combined situation of middle output, makes total flow meet current end load.
Flow of the every water pump under different frequency state can be exported by the present invention and energy consumption is monitored, and collects number
Storage, which is carried out, according to storehouse forms data form, the later stage need to can only draw the minimum pump group running situation of energy consumption by simple table look-up,
It need not be calculated by formula, programming is more laborsaving, the workload for reducing programming personnel of high degree；Fully take into account
The problem of characteristic curve of every water pump differs, the water pump of different rated power can be maintained simultaneously to enter on a different frequency
Row work, in the case where meeting total flow output, realize optimal energy consumption.
The invention also discloses a kind of recirculated water pump group most energy-saving equipment based on big data, including control unit；
Separate unit water pump data acquisition unit, for being adopted respectively to every water pump flow at different frequencies and energy consumption data
Collection；
Data storage cell, the data for being collected to separate unit water pump data acquisition unit carry out stored record；
Total flow monitoring unit, it is monitored for the water outlet total flow to water pump pump group；
Logic judgment unit, for carrying out analysis judgement to pump group running situation, screening draws the minimum operation combination side of energy consumption
Formula；
Water pump start-up and shut-down control unit, for controlling being turned on and off for every water pump respectively；
Variable frequency adjustment output unit, for controlling the frequency of every water pump respectively.
Further, in addition to wifi communication units and monitoring system, the data parameters of described control unit can pass through
Wifi communication units are transmitted to monitoring system, carry out monitoring in real time and adjustment in real time；Without carrying out data biography by communication cable
Defeated, high degree saves the consumables cost of cable, while reduces difficulty of construction.
Further, the separate unit water pump data acquisition unit includes being divided on the outlet conduit of every water circulating pump
Flowmeter, pressure transmitter and electric energy meter；In real time under monitoring different frequency, flow output situation, the pump discharge pressure of every water pump
Power situation and energy consumption.
In summary, the invention has the advantages that：Every is drawn by the monitoring of separate unit water pump data acquisition unit
Flow output and energy consumption of the water pump under different frequency state, are calculated, programming is more laborsaving without by formula；Can will not
Water pump with rated power maintains to be operated simultaneously on a different frequency, in the case where meeting total flow output, realizes most
Canon consumes.
