Abstract Snow is one of the most difficult elements to measure of meteorological elements; snow disasters every year bring immeasurable losses to the society. It will bring a serious threat to people’s lives and property security. And a light snow on railway is not serious, but heavy snow will seriously affect the transportation safety and transportation efficiency and cause an avalanche of railway safety accidents. So the snow depth measurement is particularly important. Railway snow monitoring has become an important safety factors. This article will introduce several popular snow survey methods and devices, such as laser ranging method, ultrasonic measurement, and infrared distance measurement method. The article will analyze the advantages and disadvantages of these methods and conclude which snow scene is most adapted to these methods. Finally, snow depth monitoring management system will be designed.
