| Hydro safety monitoring automation system (hereinafter referred to as system) is to meet the needs of the safe operation of water control, monitoring technology development needs, the needs of business operations for the purpose of benefit to development. This paper works on the reality of the overall design of the system:Selection of monitoring project. Vacuum laser alignment system on the Dam, dam, spillway to observe the external deformation monitoring; fixed inclinometer, soil displacement meter to observe the displacement of the dam within the internal deformation observation; to seepage, uplift pressure , pore water pressure, seepage around the dam, groundwater seepage observed parameters such as observation; for monitoring the effects of temperature on the dam for the temperature monitoring; with strain gauge, stress-free design, steel design, waterproof joint meter, crack account for the stress and strain monitoring and joint monitoring of the dam.System hardware design. The safety monitoring automation system using a distributed architecture, a sensor close to access MCU, to reduce the amount of digital and analog input from the transfer, while reducing the use of instrumentation cables. A distributed architecture to protect the stability and reliability of the system, even if a control unit problem will not affect the whole system. In the observation floor management station set up on-site monitoring, site monitoring management station through the data acquisition workstation to complete on-site real-time automated data collection. Control Unit and the acquisition by RS485 communication bus between the station and connect to wireless networks based on dual-link communication channel to communicate fully to ensure the reliability of the system of communication. RS485 communication using digital transmission, use cables to connect the transmission distance of more than 1000m, by laying fiber optic cable, transmission distances of over 20km, but also to prevent the communication bus is too long and the laying of small-scale production of the mine problem infinite. Communication data flow taking into account the smaller system, the system of communications to ensure the reliability of communication based on RS485 communication baud rate is tentatively set at 2400bps. Dam observation system using green power, in monitoring the implementation of integrated management within the management station, and set the power supply line and ground security facilities. Located in each station B, C and D level power level lightning protection devices. According to security monitoring and management system requirements for the establishment of the network function and the primary domain server, data server, WEB server and workstation.System software design. System Components include: database, model base, method base, knowledge base, comprehensive information management system, comprehensive analysis subsystem, input and output (I / O) subsystem. Underlying various types of database system is used to achieve the management of the observation data is the basis for the entire system functioning. It includes the original data collection database, database integration, analysis libraries, generate libraries, model management database, index knowledge base, the composition of the Integrated Management Database. Central is a model library system, method, library and knowledge base. Includes data processing and analysis, building security and stability of the various methods of analysis and forecasting, model and knowledge. Core of the system is a comprehensive analysis of reasoning subsystem. It is divided into offline and online analysis of two modes, extract observation data in the database, call the method base, model base, knowledge of methods, data collection and equipment status, building security and stability, the key technical issues analysis of evaluation, the decision to the observed project to provide technical support. Systems through integrated information management system to achieve a variety of monitoring data and information management. Integrated information management system to provide input, to find, arrange, output and other basic functions. System through the input and output (I / O) subsystem on the data in the database for data warehousing, analysis of peripheral output. System is under the LAN client / server architecture. System development and operation are NT as the network operating system, server-side using Simplified Chinese Windows Server 2003 Standard Edition, the client-side with Windows XP Professional Edition. Database using SQL Server 2000 Standard Edition Chinese Simplified server design and development. The client application to Visual Studio.net subsystem design and development. Visual program interface is an important part of the system is the core system functions and features of the external forms, content and form should follow the principle of unity, satisfy the system right "visual" and "transparency" of claim, seek fast, convenient and beautiful. Interface style should be as centralized as possible, using imitation OFFICE interface.
