Pumping unit intelligent control system
System composition：RTU intellient controller+DTU data collector+Four-quadrant（Two-quadrant）drive controller
RTU intelligent controller：It has various equipment control logics such as beam type,tower type,ground direct drive screw pump,etc.It can also be customized and developed according to customer needs.
DTU data collector：It is used for data collection and remote transmission of on-site operating data,sensors and other equipment ,and can be used for remote data monitoring and control through a decicated platform or small program.
Four-quadrant drive controller：It has good driving ability.When the motor is in the power generation state,the feedback electric energy can be fed back to the power grid or other electrical equipment,which has a good energy-saving effect.
Photovoltaic applications：With off-grid photovoltaic access function,no photovoltaic inverter device is required.
