  • Publication number: 20240308556
    Abstract: A device and a method for monitoring railway health in a windy desert area are provided, belonging to the field of equipment for monitoring sand accumulation of railway ballast bed. A spring vibration assembly is fixedly connected to a bracket, and the bracket and a housing are fixedly connected through fastening screws. A light-emitting diode (LED) emitter and a receiving processing assembly are fixedly connected to the housing by adhesive bonding; and the receiving processing assembly, the LED emitter and a mass ball at an equilibrium position are installed on a same straight line. The device is a novel structure, using mechanical spring vibrator as a vibration characteristic sensing unit, adapting to harsh climatic conditions in desert, greatly reducing maintenance cost, and using photoelectric sensing as a signal receiving unit, which greatly improves response speed. The device can be widely applied to railway health monitoring in large windy desert environment.
