Research of Railway Signal Detecting Method Based on dsPIC

For the safety requirements of railway transport, this paper proposes a detection method of railway signal based on dsPIC30f6014. On the basis of briefly introduced dsPIC30f6014, putting forward the method of estimating wheel position, completing fault diagnosis of sensor and the evaluation of sensor capability, show the hardware design, software design and methods of experiment. The experimental results show that this method can complete the function of railway signal detection real-time and accurately.
