Software Design of Train''''s Speed and Position Measuring System

For real-time monitoring a magnetic suspension train, a speed and position measuring system is developed. In this paper, software development of the system based on DSP is introduced. Through processing with analog signals of transducer on vehicles, we present an approach to measure the real-time speed and position of vehicles. The reasonable scheme and programming flow are chose for the system software design, which achieve A/D transform and calculations of speed and position, and the main flow chart and the main modules of the design are illuminated. The principles and the relative hardware device of the system are described as well. Experiments prove that the proposed method possesses good effect.
