Bus port 32, holding wire port 33.
Electrical network is connected with binding post 3 by water joint 2 by power supply input 1, and main control motor is given through chopper 4 in a road
The frequency-variable controller 6 of 10 is powered, and another road is given in pump group system by water joint 13 by power line 12 through water joint 5
Next water pump is powered.In like manner the power supply through water joint 13 is connected with binding post 14, a road through chopper 15 give from
The frequency-variable controller 17 of control motor 18 is powered, and another road power supply is given by water joint 21 by power line 20 through water joint 19
Next water pump in pump group system is powered.Power supply one tunnel being connected with binding post 22 by water joint 21 is through chopper
23 power to the frequency-variable controller 26 from control motor 27, and next water pump in pump group system is given through water joint 24 in another road
Controller is powered；By that analogy.Intelligent pump control system is typically made up of 2-6 platform water pump controller, and the present embodiment lists three
Illustrating of platform water pump, i.e. comprises a main control motor 10 and two from control motor 18 and 27.Power supply uses terminals
Son is the most in parallel, and connection is simple；Power supply is powered to frequency-variable controller by chopper, permissible during trouble shooting
Open failure is overhauled water pump and is not affected the power supply of other water pumps in control system easily.Water joint 2,5,13,19,21 and
The effect of 24 is the classification of waterproof improving intelligent pump control system, and degree of protection meets IP55 requirement.
Including the master driver that driver is intelligent pump control system of transmitter 9, remaining is auxiliary driver.Pressure sensing
Device 28 passes to the transmitter 9 of master driver by 8 signals of holding wire port.Signal bus 11 is by bus port 32, total
Line cap 16 communicates with the controller in intelligent pump control system with bus port 25 connection.Pressure signal is by transmitter 9
By bus port 7 output pressure signal after reason, and through signal bus 11 be connected to bus port 32 and by pressure signal transmission to
Frequency-variable controller 6, frequency-variable controller 6 drives main control motor 10 to be started by instruction, stop, accelerating or run slowly.In system
The control signal that received from signal bus 11 by bus port 16 of frequency-variable controller 17 drive from control motor 18 by instruction
Start, stop, accelerating or run slowly.In like manner, the frequency-variable controller 26 in system receives self-confident by bus port 25
The control signal of number bus 11 drives and is started from control motor 27 by instruction, stop, accelerating or run slowly.In view of different
Application and the extensibility of system, reserved holding wire port 29,30,31 and 33, and these reserved holding wire ports can connect
Connect sensor input signal (such as flow meter signal, temperature signal, vacuum meter signal etc.) and output control signal (such as Valve controlling
Signal).
Intelligent pump control system regulates the rotating speed of water pump automatically according to the signal that pressure transducer 28 feeds back.When water system
Ductwork pressure p1 need less than user setting pressure p time, frequency-variable controller 6 is automatically adjusted the rotating speed of main control motor 10 with full
Pedal system pressure requirements, if motor speed reaches maximum restriction rotating speed, ductwork pressure p1 is still below the setting that user needs
Pressure p, transmitter 9 is passed to frequency-variable controller 17 or 26 regulation by its bus port 7 by 11 signals of bus, and it drives
The rotating speed from control motor 18 or 27 of water pump, until water supply system output pressure p2=p；As p2 ＞ p, frequency-variable controller 6
Regulation main control motor 10 runs slowly；As p2 ＜ p, water pump Accelerating running；As p2=p, water supply system carries out automatic nothing
Detect with water, then autostop；As p2 ＜ p, water pump resumes operation automatically；When the setting pressure p needed is less than entrance pressure
During power p1, system does not starts, by municipal water supply pipe network directly to user's pipe network water supply.
The maximum range of sensor in system can be set easily by intelligent pump control system, set pressure, sensing
Device feedback kind, motor drive direction, PID parameters, sampling period, sleep function, dormancy relevant parameter equal proportion integration
Differential parameter, water shortage protective switch, excessive low water level protection restart time delay, water detects the functional parameters such as alarm for high voltage setting value, and
The Protection parameters such as the protection of overload protection electric current, overvoltage stall protection, current limliting, input phase failure, output open-phase protection.Intelligent pump controls
System can also arrange systematic parameter, such as function, system start-up Auto Power Ons such as motor mode setting, electricity, working time, states
The function setting such as function, motor numbering, motor-locking and display etc..
This intelligent pump control system is provided with the system failure or water system fault message and historical failure information etc.
The query function of warning message, city planting ductwork are cut off the water defencive function, and low discharge sleep mode and having a power failure is not cut off the water.Work as community
During power failure, city planting ductwork continue to supply water to low district user, after equipment restores electricity, automatically start, recover stopping of normal water supply
Electricity continues to supply water.
