Research And Implementation Of NoSQL Visualization System Based On Real-time Monitoring Of Substation

In recent years, along with advances in computer technology, the large number of applications continues to improve high-speed communication networks and intelligent electrical equipment, making substation monitoring system gradually toward digital and intelligent direction, which means the substation data are quickly grow with, how fast analysis, processing, display this information becomes increasingly important.With the rapid proliferation of smart devices to mobile office has been more and more popular, in order to enable users to monitor anywhere, health query substation, and taking into account the monitoring system compatibility and upgrade each platform convenience and other factors, the use of B/S architecture design system is a good choice. Given the amount of data increases, more and more prominent single performance bottleneck, so in an efficient, reliable, economical and safe as the goal, to build a distributed system has a lateral extension and disaster recovery capabilities has become an inevitable trend.In this paper, starting from the actual needs of the substation, after study of the relevant technology to achieve this system. The system is based on application development to enhance the efficiency and efficient handling of large amounts of data considerations, use the characteristics of its document data model and relational model solves the memory data structure does not match the problem; the use of its automatic load balancing feature will deploy data evenly across multiple server nodes to enhance the amount of spit swallow systems; by way of a replica set of redundancy for each slice, to ensure the reliability of data; using maps-simplification and aggregation technology, complete system statistics and analysis of large amounts of data. In addition, the system in order to allow users to access information more intuitive, extensive use of visualization techniques:the use of SVG technology to display equipment wiring diagram, combined with server push technology to show the device to measure real-time information, but also use FusionCharts library to display statistical results chart. To solve the problem the user to repeat the work using Jacob components and Java Mail, to achieve a statistical reports automatically generated and sent to work.
