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.
