Design And Implementation Of Gas Control And Management System

The world is still in the global economic crisis, but it is estimated that growth of Chinese economic can still reach 8%. Demand for energy is to grow. Meanwhile, the standard of people's life is rising steadily on the demands of living environment increasingly high. Oil and coal are not easy to burn fully and produce toxic gases, but gas doesn't. With the continuous development of storage and transport technology of gas, gas will be more widely used. In some ways, gas began to replace coal and oil. Managing the scheduling and pipeline maintenance of gas effectively or not will be very important to applications of gas.Gas control and management system uses the application model of B/S architecture which uses three-tier layers, including presentation layer, business logic layer, and database layer. Presentation layer uses the Flex rich-client technology to provide better customer experience. Business logic layer uses EOS workflow technology that can achieve real-time monitoring of work flow and improve the efficiency of the management. The data layer uses Oracle. Gas control and management system uses proactive caching technology to realize the client auto-response the changes of the database. The system uses service-oriented Bus Technology, which makes new business when it is the Necessary, from the service bus to find needed services, arrange in some order and call each service. Various functions will be divided into Web Services in accordance with certain size. When other system needs, this function can be called in the form of Web Service. The system's data flow uses the data bus of EOS format for data transmission, to facilitate various businesses to be called in EOS workflow normally.The system can be used in three field, gas management, pipeline maintenance and internal management. The system can satisfy the needs of the company. It has a friendly platform which can be used easily and commonly.
