People on the elevator safety, efficiency, comfort the constant pursuit of technological progress to promote the elevator. Lift the quality of good or bad depends largely on its control system. At present, the elevator control system has largely eliminated the traditional relay control mode. Integral controller based on PLC is the core digital control system. PLC, which has advan
