某大型港池造波机控制系统智能化改造研究

Research on the Intelligent Transformation of the Control System of the Wave Maker for a Large Harbour Basin

某大型港池多向不规则造波机系统投入使用已有10余年,由于该造波机控制系统软硬件技术落后,存在计算速度慢、故障率高和传输速度慢等问题,无法满足目前波浪物理模型试验复杂波谱及长历时无重复不规则波试验的需求。为了更加精细、准确地实现高品质波浪谱模拟,故对该控制系统进行智能化改造,构建了基于EtherCAT总线的多向不规则造波机控制结构。

The multi-directional irregular wave maker system of a large harbour basin has been in use for more than 10 years.Due to the outdated software and hardware technology of the control system of the wave maker,there are problems such as slow calculation speed,high fault rate and slow transmission speed,which cannot meet the current needs of complex spectrum and long-duration non-repetitive irregular wave tests in wave physics model tests.In order to achieve high-quality wave spectrum simulation more finely and accuracely,the control system is intelligently transformed,and the control structure of the multi-directional irregular wave maker based on EtherCAT bus is constructed.
