摘　　要：船闸是水运交通的重要枢纽,而闸门是其重要组成部分,一旦闸门发生故障会给航道运输带来巨大损失,因此对于闸门的状态监测十分必要。现有方法以振动监测最为常见,主要监测闸门运行时的振动情况,但该方法监测量单一,缺少振动引起的闸门形变、倾斜情况和开合状态监测。针对该问题,以有限元分析为指导,以振动监测为基础,研制了一种多传感融合的闸门状态监测系统。该系统可实现闸门的实时振动频率、开合角度监测和长期倾斜监测,为闸门状态监测提供一种多传感信息融合的监测方法。在江苏省谏壁船闸的测试应用,证明该系统可以实时掌握了解闸门的运行状态,为船闸的安全运行予以保障。The ship locks are critical parts of the waterway,and the gate is an indispensable part of the lock system,which brings great losses to the waterway transportation once it fails,so it is necessary to monitor the status of the lock gates.The vibration monitoring is common in existing methods and it mainly concentrates on the vibration when the gate works,however,it is single because of lacking tilt and working state of the gate caused by vibration.In view of the problems,a multi-sensor fusion status monitoring system of the lock gate is designed which based on the finite elements analysis and vibration monitoring.The system can conduct the real-time vibration frequency,angle monitoring and long-term tilt state monitoring,and provide a multi-sensing information fusion method for the gate status monitoring.The practical application in the Jianbi locks in Jiangsu Province proves that the system can acquire and master the working status of the lock gate in real time,and safely guarantee the routine work of the locks.
