Abstract: Wujiang Junction is composed of control gate and Wujiang pumping station, which is an important part of Simashan river diversion irrigation project. Before the renovation, there are some problems, such as pressure measuring pipe blockage and non-standard cable layout. Through a large number of investigation, analysis and research, the final determination of Wujiang Hub safety monitoring automation transformation scheme. The transformation plan includes replacing the artificial settlement measuring point with a three-dimensional displacement monitor, transforming the tilt and crack observation point into an automated device, and realizing automatic data collection and early warning through the Internet of Things. The data platform is not intuitive, the equipment structure is not adapted to the harsh environment, and the snow affects the accuracy of the data. The solution includes repairing the pressure tube, optimizing the cable layout, redeveloping the monitoring data platform, improving the equipment design, adding protective covers, etc. After the transformation, the automation degree of monitoring technology, the applicability and sensitivity of equipment have been significantly improved, and the independent deployment security monitoring platform developed by the transformation has also been successfully launched, realizing the real-time monitoring, analysis and early warning functions of data. After the completion of the automatic transformation, the reliability of the safety monitoring system is greatly improved.
