Miter gate closing alignment control system
A miter gate closing end alignment control system comprises door slot detection devices installed on two miter gates, real-time door slot state detection data of closing operation closing end alignment of the miter gates are automatically collected, and the real-time door slot state detection data serve as feedback information and are transmitted to a ship lock PLC control system through a data line. The PLC adopts a control algorithm to compile an operation program, compares the real-time door slot state detection data with door slot target value data, converts error data obtained after comparison into rotation angle errors of the two miter gates when the door slot target value is closed, and controls the algorithm according to the rotation angle errors and the motion relation of the miter gate opening and closing mechanism. And the PLC performs operation to obtain the residual driving time before the driving mechanism drives the miter gate to be closed, and the miter gate is finally closed, aligned and shut down. A closed-loop control loop is formed, direct real-time control over the miter gate final-closing alignment door slot target value is achieved, and continuous and stable miter gate closing operation final-closing alignment precision is achieved.
人字闸门关终对位控制系统，包括安装在两扇人字闸门上的门缝检测装置，自动采集人字闸门闭合运行关终对位的实时门缝状态检测数据，实时门缝状态检测数据作为反馈信息通过数据线传输到船闸PLC控制系统，PLC控制器采用控制算法编制运算程序，将该实时门缝状态检测数据与门缝目标值数据比较，并将比较后所得的误差数据转化为两扇人字闸门分别距关终门缝目标值时的转角误差，根据该转角误差和该人字闸门启闭机构运动关系控制算法，PLC控制器运算获得驱动机构驱动人字闸门闭合运行关终对位停机前的剩余驱动时间。本发明形成闭环控制回路，实现对人字闸门关终对位门缝目标值的直接实时控制，达到人字闸门闭合运行关终对位精准度持续稳定。
