The design of hardware and software is the emphases of this paper, the hardware circuit board which has an ARM core-S3C44B0 is designed for the special situation and use, for the locoman it is easy to operate and it has a friendly interface. The application software is designed on the embedded operating system-uClinux, it is more complicated than the software which is not base on the operating system, but it has more functions than the latter, furthermore it is steadier when running, and it is easier to design when the operating system has many API functions to use.

本文的重点也在控制部分的软硬件设计上，针对本系统的特殊应用，设计了基于ARM芯片S3C44B0的硬件电路板，它完全满足机车操作人员要求的交互作用好、便携，抗干扰的要求；软件部分采用基于嵌入式操作系统uClinux的应用程序，它与一般的前后台系统下的应用程序相比更复杂，但它所实现的功能也是后者望尘莫及的，并且基于操作系统的应用程序运行更稳定。
