Design Of The Field Operation System For Marshalling Station Based On PDA

The system bases on the condition of Freight Classification Computer Integrated Process System (CIPS). It will be implemented in marshalling station which has the flat of information sharing and exchange of information. This paper presents that field operators communicate with inside operators using PDA for the first time. Its design, development and application accomplish that field operators examine the train information at any moment, avoid the possibility of information's disaccord during the train information's transmission and improve field operators' work efficiency greatly.In this paper, the requirement analysis and design of system based on the environment of CIPS will be presented according to the method of software engineering, and each function of this system has been achieved and tested carefully.The paper's main content consists of introduction, correlative technologies' introduction, requirement analysis, general design, detailed design, capability analysis and function demonstration. In the introduction, the background, the civil and oversea actuality, the way and significance of the study are described. Then the correlative technologies are introduced. Subsequently, the requirement is analyzed. The general design that consists of main function, system framework, the modes of information's exchange and communications will be presented; after that, the detailed design that consists of communication regulation and the flow of main function will be presented based on the general design. At last, we analyze the capability of system in detail and demonstrate some main functions of system. In the conclusion, the innovation and shortage of system are described.The system has already satisfied the consumer under the condition of experiment and will be tested more out of door next.
