Adopt ARM processor and external hardware circuit to assemble an embeded acquisition system of train signal. This system is complete and reliable. It can accurately measure the signal loop current RMS which will be sent to the monitoring equipment as required at the same time. The computing speed is fast, and the sampling accuracy and speed improves a lot. Sampling can be carried out several times in a half cycle. We take a series of links such as hardware filter, transformers isolation and software filter to process the input signal so that the external interference would be avoided. The system works well to predict the reliability of the signal fault.
