基于EtherCAT的“透明”泵站SCADA系统设计

Design of “transparent” pump station SCADA system based on EtherCAT

为满足现代水利系统"无人值班、少人值守"的要求,解决传统排灌系统自动化程度低,控制和管理相脱节等问题,将EtherCAT的通信技术应用到泵站数据采集与监视控制(SCADA)系统设计中。通过对"透明"远程泵站SCADA系统设计需求和技术方法的分析,采用"PLC+EtherCAT"的方案对堤段泵站进行了远程监控和管理,实现了对现实工程中的"全透明"的堤段水利管理。研究结果表明,基于EtherCAT的SCADA系统可以实现对泵站远程设备进行有效的"透明"访问和管理,整个系统在实现水资源综合管理、合理分配与利用的同时,也提高了泵站运行管理效率,实现了水资源管理的科学和高效的决策。

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.
