| Abstract: | A automatic load system of surveilling and controlling air pressure was presented. In this system, the combination state software MCGS and touch screen served as the host computer respectively, Siemens PLC226 served as the driven computer, and the PLC controlled the electric/air converter. The system was employed to simulate the water pressure of the bank of the three channel dam. The measurement precision of pressure is less than 0.3% and the control precision is less than 0.7 % when the loading air pressure is more than 0.9 MPa. |
