nt and maintenance.(2)The application software which has high efficiency, high reliability and maintainability, adopt the modular design for easy expansion and modification.(3)The functional software modules or the mission module has the integrity and independence, and the design of the software environment enables the staff to safely realize the plementarities and modification of the application software. Video System Software The frontend software of the video surveillance system is installed in the sluice gates, including pression software for image data acquisition, system control software and transmission software of network data. It not only control the vidicon and cloud platform at the scene, but also implement the order of video frequency control form the superior water dispatching center.The video surveillance software is installed on the puter in the sluice gates place, which is responsible for the functions of the management of video equipment, image monitoring, alarm processing, realtime control.4. ConclusionThe system is designed authority setting for all levels monitoring stations, especially the design of the hoist control at the scene and the fault protection function. The reasonable set of the limit authority in each level monitoring stations can resolve the conflict between the current and the remote, and provide emergency measures,therefore, it can promote the system function to be more secure and perfect. The flow of water diversion in the sluice gates can be confirmed by accurately determining the water lever before and after the sluice through ultrasonic water level gauge. In the course of the study, the realtime voice dialogue system is added to realize the function of realtime voice calls, which also perfect the system.The implementation of remote monitoring systems can achieve the five level controls, which are Yellow River Conservancy Commission, Provincial Bureau, City Bureau, County Bureau, and the field. Each level can grasp the function of the sluice gates under its rule, and can open and close the sluice gates in the current or the remote. Therefore, integrated water regulation of the Yellow River and optimal allocation of water resources e true. The realtime scheduling of information of the Yellow River water diversion and the projects can improve the modern management of the sluice gates. It is of great significance to ensure the flood control safety, no zero flow happen and promotes sustainable socioeconomic development in the downstream region.15 / 15。(2)The adequacy of the puter storage is over 40%。(3)Any hardware and software failure doesn’t affect the safety on people and system。 Guarantee measures for hardware and software(1)Power failure protection。(2)When the high level of water allocation center and the field monitoring system has control message, it should has clear and confirm mand。(3)A control right mand is used on manputer munication。(8)The average maintenance time of a failure is in 30ms. Available rateThe system design should adopt high reliability ponents, the realtime operating system should has practical running experience, the software should be practical, then the system can obtain high availability. The total failure time of the system should not exceed 1% of the running time during the oneyear guarantee time of after one year trial operation and eq
