| Liaoning Power System is an important part of Northeast Power System and a modern Power System. Modern power systems need modern management system. As an important part of information system for power system dispatching, a perfect set of maintenance ticket management system can not only ensure making the maintenance plan reasonably and improving the efficiency of power system, but also be very important to the safety of power system. Recently, the computer and network development offers a great technical support to the development and application of the maintenance ticket management system for its efficiency and simplicity. Liaoning Power Patching Communication Center Operation Office is responsible for the power operation mode arrangement, new equipment transportation, operating equipment maintenance, voltage without power management, and etc. With the power capacity expanding, the number of equipment is becoming large and the workload of maintenance plan also doubles. As a result, the numerous complicated businesslike work block the work of maintenance people. The old acceptance through telephone, filling out manually, and endorsing the maintenance tickets can't satisfy the power development. The old mode is not convenient for arranging the restriction condition of power safety and stabilization and protection changing. Even, the error odds is high. At the same time, with the old mode, the querying is a big trouble and very difficult to manage the maintenance cycle and know when to maintain the equipment. A advanced set of management software can disengage the people from the hard work and study the new technology and theory. Also, people can fix attention on studying how to arrange the maintenance plan and it is good for the safety of power.The whole system focuses on application. According to the equipment operating status, maintenance cycle, periodically maintenance cycle, and extensively maintenance cycle, the system can make plan for periodical and extensive maintenance of equipment and circuitry and add the involved work into the maintenance plan. Even more, it can fill out the maintenance ticket and copy the data into the database through computer network. It can work without paper. The maintenance ticket system uses the distributed multiplayer system based on J2EE. On this system, the data calculating and processing are performed by client computer and the old data server is now the data base server, which is only responsible for the data storage and maintenance. The client program of maintenance ticket management system is an explorer that focuses on processing the user logic and showing the result instead of processing the complicated data. Therefore, under this mode, the client program is relatively simple.Whether the clients use HTML or Java Applet, the client dynamically download the data from operation logic layer when users run the client program, which can reduce the codes largely. If the system functions need to be changed or extended, it is only needed to add the operation logic code in operation layer instead of changing every client to adapt to the new system.Data layer is the DBMS that is responsible for managing the data and performing the read and write operation in answer to the client request. DBMS can perform data updating and searching. The operation layer can operate the data layer by SQL.In the maintenance ticket management system, we use middle components technology. The middle components are mainly responsible for passing the client requests and locating the objects determined by clients on cyber space. When many departments apply the maintenance tickets simultaneously, the middle components can harmonize the request threads and make the system be able to process the simultaneous affairs. At the same time, the middle components keep the connection with database and speed up the data responding and processing.Without decision-making supporting system, we can't make the maintenance tickets automatically. The maintenance tickets management system uses the artif... |
