The automatic control system based on PLC in concrete's grouting and vibrating project

Based on the problems in hydraulic engineering construction and requirements of the concrete control system, combined with research status, the concrete vibrated and injected automatic control system with PLC is designed. The paper introduces configurations and principles of the control system which is based on PLC and HMI. This system is convenient to mount and maintain, stable to work, reliable to operate and precise to control. The system has abundant functions and kind interface between users and the machinery, which has a good prospect.
