Embodiment
Referring to Fig. 1, a kind of general photovoltaic water pump system, include photovoltaic cell plate array 1, DC/AC transducer 2, motor 3, water pump 4, level sensor 5, controller 7 and man-machine interface 8, photovoltaic cell plate array 1 is electrically connected with motor 3 by DC/AC transducer 2, and motor 3 is electrically connected with water pump 4; Have motor position feedback interface 6 on the controller 7, and be electrically connected with motor 3 by motor position feedback interface 6, level sensor 5 and man-machine interface 8 are electrically connected with controller 7 respectively.
In the utility model, photovoltaic cell plate array 1 is comprised of a plurality of photovoltaic cell plate serioparallels; Level sensor 5 includes well level sensor and the water tower level sensor that is installed in respectively in well and the water tower.
The photovoltaic cell plate array absorbs solar energy, changes into direct current energy, is reverse into Ac by inverter, drives AC motor, drags water pump and pumps up water.
The water level information that the well level sensor obtains through translation interface, is input to main control chip, determines thus whether finish to pump up water, and is dried to avoid well to beat, the injury pump.
The water level information that the water tower level sensor obtains through translation interface, is input to main control chip.Low water level occurs and then begin to pump up water, excessively low to avoid water tower level, affect the user and use, high water level occurs and then stop to pump up water, overflow to avoid water.
Motor position sensor provides position information for permagnetic synchronous motor drives.
Man-machine interface can the display system state, and concrete Operational Limits provides the parameter setting, and function is selected.
Behind the system boot, judge current motor type, the method for operation different according to different selection of Motor.Also can select different V/f curves for different induction machines.
