Abstract： Aiming at the requirements of modern irrigation system“unattended，fewer people on duty”，solving the problem of low automation degree and changing the disjointed state of control and management in traditional system，EtherCAT communication technology was applied into the design of the pump station supervisory control and data acquisition（SCADA）system. Based on the analysis of design requirements and techniques for “transparent” remote pump station SCADA system，the proposal of “PLC+EtherCAT”was adopted to make a remote monitoring and management for the pumping station of embankments. A kind of “full transparent” embankment water management was realized as the practical engineering case. The results indicate that the SCADA system can effectively make a “transparent” access and management to remote device of pump station. The entire system not only can integrate water resources management，rational allocation and utilization，but also can improve the efficiency of the pumping operation and management，achieved a scientific and efficient decision-making of water resource management.
