Abstract
Uses programmable controller PLC to replace the relay controller, carries on the control to machinist's hydraulic pressure driving system, through the input output interface establishment with the machinist hydraulic system switch quantity and simulation quantity's contacting, realizes the machinist to transport the work piece the smooth movement and the automatic control, achieves the accuracy to be high, the control is convenient, the reliable good goal, raised the productivity and the automaticity greatly, saves the hardware cost, to cut the failure rate, achieves the energy conservation efficiency the goal, has the very strong usability.
