摘要
船厢门、防撞装置的稳定运行对向家坝升船机运行流程具有决定性的作用,是计算机监控系统的核心部分。针对船厢门和防撞装置的运行工况,控制系统采用模块化分层设计,在传统控制的基础上对行程编码器及接近开关的使用进行优化,建立流量-比例随动模型,采用预提定位、电机轮泵及五段速度控制,判断闭锁与故障。试运行表明,该系统在保证控制系统稳定、可靠的同时实现了毫米级的控制精度,完成了液压启闭机系统的控制。
The stable operation of the chamber gate and anti-collision device plays a decisive role in the operation process of Xiangjiaba ship lift,and is the core part of computer monitoring system.For the operation conditions of the chamber gate and anti-collision device,the control system adopts modular layered design.By optimizing the use of the stroke encoder and the proximity switch based on the traditional control,the flow-proportional follow-up model is established.The pre-positioning and motor wheel pump and five-section speed control are adopted to judge the atresia and fault.The trial operation shows that the system can ensure the stability and reliability of the control system and achieve the millimeter level control accuracy,as well as complete the control of the hydraulic hoist system.
