With motor 15.Main driving controller I and from drive controller II respectively by electrical network by chopper 9
Powering with chopper 11, its communication line is interconnected by bus 10.Due to from driving controller II not
Comprise frequency-variable controller, thus its motor 15 rotating speed controlled be non-adjustable, can only power frequency operation, thus
Reduce the cost of control system of water pump.
The signal that frequency-variable controller 1 on main driving controller I feeds back according to pump group delivery gauge 3
Regulate the rotating speed of water pump automatically: when the ductwork pressure p1 of water supply system is less than the setting pressure that user needs
During power p, the rotating speed of frequency-variable controller 1 self-regulation motor 2 is to meet system pressure requirements；If
When motor speed reaches maximum restriction rotating speed, ductwork pressure p1 is still below the setting pressure p that user needs,
Main driving controller I is passed to from driving controller by 10 signals of bus by its bus port 8
The input port 13 of II, catalyst 12 action after receiving signal from driving controller II, start electricity
Machine 15 power frequency operates, and frequency-variable controller 1 regulates the rotating speed of motor 2, until water supply system output pressure
P2=p；As p2 ＞ p, frequency-variable controller 1 regulates motor 2 and runs slowly, if motor 2 speed
Being transferred to minimum definite value, p2 ＞ p, main driving controller I pass through its bus port 8 by bus
10 signals pass to, from the input port 13 driving controller II, receive from driving controller II
Catalyst 12 action after signal, motor 15 shuts down, and frequency-variable controller 1 regulates turning of motor 2
Speed, until water supply system output pressure p2=p；As p2 ＜ p, water pump Accelerating running；Work as p2=p
Time, water supply system carries out the detection of automatic useless water, then autostop；As p2 ＜ p, water pump
Automatically resume operation；When the setting pressure p needed is less than inlet pressure p1, system does not starts, by
Municipal water supply pipe network is directly to user's pipe network water supply.Output port 4 exports in control signal control system
The assembly such as electrically operated valve.Input port 5 accepts the feedback signal of sensor in system (such as stream
Measure signal, without water conservation signal), pump group system is controlled by frequency-variable controller 1 according to feedback signal.
Main driving controller I is provided with ECP Extended Capabilities Port 6 and bluetooth port 7, is used for realizing the network interconnection.
Bus 10 is passed through by inputting from the running status of 14 motors 15 of output port driving controller II
Port 5 is sent to main driving controller I.The acquisition system motor 15 of main driving controller I timing
Running status, thus be pressure and the flow accurately controlling water supply system.
Additionally, when having the main driving controller I of group with in time driving controller II, multiple stage is main drives control more
The life-span with motors all in equalizing system of automatically switching can be realized, it may be assumed that control system between device I processed
Completely count the hours of operation of every motor, and adjust the boot sequence of motor accordingly, when running accumulative
Between the minimum motors of number will first start, running cumulative time maximum motor will finally start.Control
System running pattern is divided into automatically and manually, it is simple to debugging or fault diagnosis and analysis.
