Research And Implementation Of Real-time Data Transfer In Real-time Control System

With the rapid development of network hardware and software, the real-time control system has been paid more and more attention to, more and more research has been done to satisfy the need of human life. It offers ways of distributing collaborative work and makes geographically distributed teams collaborate on a particular item over the Internet; it also opens up a channel for e-business and e-learning. Engineers can monitoring and maintaining remote individual plants without walking into the plants and checking the equipments by themselves. Real-time control system brings us high efficiency and low cost, but it also offers a new challenge to network technologies, that is real-time data transfer. It is one of the key technologies that real-time control system must resolve.The open nature of Internet and the real-time data itself makes the real-time data transfer being extremely difficult. A server is connected by several clients around the world in different ways. Data of various data formats comes from multiple sources and platforms. Some large data, such as picture, video, audio overload the Internet and might result in unacceptable time delay, data loss and even whole system collapse.In this thesis, after introducing real-time control system, XML, HDF5, the real-time data wrapping method based on XML and HDF5 is described in detail. And the transfer mechanism based on RMI is also brought out. And the wrapping method and the transfer mechanism are implemented when designing the F1 car racing real-time simulation control system. Good results are carried out from the simulation.
