Implementation Of Transmission Lines On-Line Monitoring Backstage Query Software On B/S

High-voltage transmission lines are the arteries of power system. The generalization and application of transmission lines on-line monitoring technique are the inevitable requests to make power system work well and to increase the transmission capability of power system. Damage of transmission lines forced by extraneous force destroying, meteorological hazards and aging of line poses a great threat to security and stability of the grid.A series of faults will appear in the process of transmission line operation, such as too high of the wire working temperature, changes of the wire sag, windage yaw discharge, contaminated insulator, etc. So checking the lines and timely finding defective equipment and hidden trouble are very needful. But the current check method is still more use of the traditional artificial way, existing big workload shortcomings. Monitoring data of transmission line conductor by remote on-line monitoring technology can reflect real-time operational status of transmission lines as well as warn the line faults timely.Based on the related technology development of the transmission line on-line monitoring system, and the basic ideas of B/S model application system, this paper builts based on B/S mode transmission lines on-line monitoring backstage query software. The main work is as follows:1. The principle of transmission line on-line monitoring system are analyzed, and the overall architecture, main monitoring objects, and their implementation in the process of the communication have carried on the preliminary discussion and research. Then the paper builds a based on B/S mode of transmission lines background check online monitoring software.2. The paper combines with dynamic web page technology and database technology effectively. After comparing all kinds of dynamic web technology, the PHP technology is applied to the transmission line on-line monitoring backstage query software. The paper completely bases on B/S model, solves the inconsistent platform caused by multi-user diversity, and the multifarious need to develop different client application, realizse that multiple users can be on a visit to transmission line on-line monitoring software for background without being limited by the space, which have very strong practicability.
