Research of artificial wave-maker monitoring system based on PLC and PID

针对气动造浪系统的特点及运行的需要,设计了基于PLC(Programmable Logic Controller)和PID技术的气动造浪监控系统。采用PLC完成了多点造波风罩的压力数据采集和对人工造浪系统的现场控制,采用PID技术实现了造波风罩压力的精确测量和对控制系统实现恒压控制,并建立了气动造浪系统上位机软件用户模块。使用该具有PID反馈的系统不仅保证了气动造浪系统正常运行,而且具有节能效果,也为开发人工气动造浪系统提供了良好的启示和借鉴。

According to the characteristics of pneumatic making waves system and the needs of operation,pneumatic wave- maker monitoring system was designed based on PLC and PID. The multi point wave hood pressure data acquisition was got,and it could realize local control the artificial wave system by PLC. It realized accurate measure on the wave hood pressure and the constant pressure control on control system using PID technology,and epigynous machine software user module of the pneumatic wave system was built. The system with PID feedback not only ensures the normal operation of pneumatic wave system,but also has the effect of energy saving,and it provided a good inspiration and reference for the development of similar systems.
