Rebuild And Implementation Of The Safety Monitoring Automated System Of Wu Jiang Dongfeng Hydropower Station Hub

The aim of renovation of the safety monitoring system of WU JIANG DONGFENG hydropower station hub is that we can grasp operation status of dam. Under inspecting and monitoring the dam from time to time, the first-hand observed data will be provided quickly and correctly for engineering security management. Meanwhile, decision maker will obtain reference materials immediately.Research technical methods of renovation of system include intelligent distributional Geomation 2380 data acquisition system,field bus (optical fiber) communication way, and the local area network established through the optical fiber bus, the network server, the switchboard. The local area network designs the network model is two levels structures: the group and desktop. The development of communication management software mainly uses Microsoft's newest development kit Visual Studio.net development and complete under windows2000/XP/2003 system, the analysis computation part uses Digital Fortran 6.0 and so on developments to complete, the database uses Microsoft SQL the SERVER 2000 database. Aiming at the practical situation of the projects, several monitoring mathematical models which mainly inspected physical quantity have been established such as single-point statistics, mixed models, one-dimensional, two-dimensional distribution model and so on. In addition, monitoring indicators and online monitoring have also been settled and taking advantage of a type (the Rules) expert system is to achieve a comprehensive analysis of the Separation Line reasoning.The main tasks for design and development of the system's renovation system includes: carried on development and transformation to the Geomation 2380 acquisition systems and survey module of Kaerxun, and solved the phenomenon when the original Geomation 2380 collection module measurements take measure to the Kaerxun equipment always not accurately. Established the observing local area network, solved the connection of the data acquisition system and the information management analysis system to realize the possibility of online monitoring as well as the real-time analysis and the information inquiry of the dam security too, established the interfaces for comparison the manual survey. The software module matched with the artificial input data and the semi-automated monitoring system data interfaces.Through the monitoring automation transformation, embedment instrument of DONGFENG hydropower station hub hydraulic structure basically has been turned on the automation, and achieved online observation...
