Abstract
The utility model provides a control system of a hydraulic power unit. The control system of the hydraulic power unit comprises an industrial personal computer, master stations, transducer stations, power stations, slave stations, sensors and control valves. The industrial personal computer controls a plurality of master stations through communication lines. The master stations are connected with one another through the communication lines. Each master station is connected with a plurality of slave stations and a transducer station through the communication lines. Each power station is connected with a plurality of slave stations through power wires. Each slave station is connected with the sensors and the control valves, and the sensors and the control valves are arranged on pipelines of four jacks. The control system of the hydraulic power unit is capable of reducing personal error, preventing the pipelines from being connected in a wrong way, and reducing ancillary work time. Through adoption of a modular structure, the control system of the hydraulic power unit is convenient to carry and install, flexible in mobility, and capable of greatly reducing technical content required by installation, reducing the number of constructors, relieving labor intensity and improving efficiency.
