Design And Implement Of Web Technology In Gas Distribution

The design of the gas supply includes something such as gas distribution, adding smell and pressure to gas,temperature controlling and so on. Among them, the gas distribution is the most important thing for each gas company. If the gas distribution is not reasonable, making the gas net pressure lower, it can't satisfy customers; And making the gas net pressure higher, the gas company's expenses will increase. Therefore doing the best to satisfy customers and lower the gas company's expenses is a very important problem that a gas company should deal with.In the design , Gas distribution center can watch and controll pressure stations and storage stations using IE by internet.Embedded collection system(including Web server) collects bottom datas in pressure stations and storage stations. Web technology is applied to communicate distribution center with watched stations.Mathematics model of gas distribution dispatching is realized by Java Applet and put into Web server.while be long-rangely visited,the related distribution model is run.The gas net distribution system is a multi-dimension and a dynamic non-linear system. In the design, the customer satisfaction degree to be the best is the target function. The variability is the assigned rate which distributes to next gas pipe. Without regard to the effect that temperature etc.take,creating gas distribution dispaching model,designing and writing the gas net distribution program with the dispatching rules "looking for the extremum of N dimensionalities under the contain condition " to adjust distribution control system automatically.According to this,we can achieve dispatching model's program throgh Java Applet.The design takes Web technology to achieve buttom communication of watched satations. we apply an excellent open-source operating system--uClinux, which has an outstanding network performance. And we put up a developing and compilation environment on a host computer for it. Then we compile a kernel and plant document system. The microprocessor we use is LPC2294 for Philps Corp. As for the hardware on the target board, we mainly design Ethernet and RS-485 interface,memorizer extension.Then the design constructs a Boa Web server,completes dynamic Web technology, finishs distribution system's model of math in embedded macro-controller through Java Applet and realizes man-machine communication.
