Design And Implementation Of The Multipoint Axle-Counter System Based On Windows CE

Axle-counting Devices are used to perform real-time check of the status of railway sections, which are occupied or not. The functions are equal to that of track circuits. The operational principles are based on the computation result using the axle-counting information in the section. At present, track circuits are wildly used in our country. But they are easily influenced by circumstance such as low roadbed bleeder resistance, bad shunting, etc. These instances make wrong operations occur and lead to the malfunction of signaling interlock. These circumstances baffle the improvement of safety and the train speed. Axle-counting devices are not influenced by the circumstance has mentioned, and can ensure the transport safety.In this paper, the requirements and specialties of the intra-station multipoint axle-counting system are studied. Then with the integration of computer technology, network communication technology and automatic control technology, a kind of solution is proposed, in which the embedded real-time operation system, Windows CE .NET is used.The contents of the paper consist of introduction, system framework design, hardware design, introduction of Windows CE, software design and implementation, etc. In the introduction, the background and the significance of the study in the system are described. In chapter 2, the analysis for the system requirements is described, and the system framework is designed. Then the system hardware design using two voting method is described by analysis. In chapter 4, the procedure of developing and customizing Windows CE operating system, and of the application, is introduced. In chapter 5, the Object-Oriented technology is applied, and the software of the system is designed and implemented. At last, the design and the implementation are summarized, and the methods which can improve the system are described.
