Regarding the problems of traditional protection zone operation and safety management,such as manual-based management,low information utilization and lack of dynamic assessment and early warning,this paper combines the main issues and requirements of the operation safety control of the protection zone in Longxikou navigation-power Junction,and aims to innovate the operation and management mode,strengthen information interconnection and sharing,and improve the level of intelligent control.Then,a multi-level system structure integrating online data identification,flood monitoring and prediction,real-time safety diagnosis,dynamic risk assessment,and early warning response decision is constructed,and the implementation path and technical requirements of core functional modules such as real-time flood monitoring,flood risk assessment,safety analysis and risk assessment of flood embankment are proposed.The research results provide technical support for comprehensively improving the disaster prevention and mitigation capability and security level of the protection zone in Longxikou Navigation-power Junction.
