Research Of Locomotive Intelligent Display Unit Base On Windows CE

The IDU (Intelligent Display Unit) is an important equipment to offer the human-machine interface and show significant information of the locomotive. The display guides the trainman's operation and assure locomotive of its safety. It is clear that there has a lot theoretic and realistic meaning on the research of theoretic method and technological realization of the IDU.Research was done in the domain of ARM920T, and of real time operation system Windows CE, of the embedded OS driver and CAN bus during the author finishing the master thesis. The platform of hardware and software of IDU based on Windows CE was accomplished.The S3C2410 developing board was chosen as the hardware platform of IDU. Base on the hardware a Windows CE OS was constructed, which is fitting to the IDU. And the work includes designing boot loader, cutting out kernel; developing application software and making PCB had been done. Because the standard WinCE kernel can not suffice for the need of the IDU, the author changed a lot in BSP for the requirement of it. Although S3C2410 with ARM9 kernel own plenty of peripherals, there is a lack of CAN controller, which is popular in industrial application. MCP2510 was used to realize the communication via CAN bus, PlatForm Builder and eMbedded VC++ was used to design the CAN driver and develop GUI of the IDU.At last, a comparison between the IDU and the previous version display was give, which testified the add-in and changed functions of the platform is innovative and useable.
