Digitization Transformation Of Leveling System Of Tamp Trains Based On ARM

With the widespread use of tamp trains in railway construction and maintaining, the investigation of tamp trains has been increasing and the control system of tamp trains is becoming more and more important. According to characters and analysis of the current tamp trains, a digital system based on S3C44B0X is designed to improve inspection ability, cut down the power dissipation and reduce the cost.The system is composed of hardware and software. The kernel of the hardware is a digital system based on S3C44B0X, it achieves analog signals to digital signals transition, data collection, control, display and signals magnification. The kernel of software is under control of uClinux, which is made of some threads, it achieves the functions of originally system. This paper illuminates the constitutes of hardware and software in detail and discusses some key problems in theory. Many effective methods are proposed, which are shown as follows: 1.The leveling system of tamp trains is analyzed. According to the actual requirements, a hardware system based on embedded system S3C44B0X is designed. 2. The circuit board is debugged and the problems during the debugging process are resolved. 3. With the limit of hardware, the primary functions are realized and the performances are improved.
