With the development of superconducting materials,superconducting train technology is developing rapidly.Aiming at the problems that high-temperature superconducting maglev trains will affect the track system during operation and that traditional electronic sensors are difficult to achieve stable and reliable measurement under strong magnetic environment,a track monitoring system of high-temperature superconducting(HTS)maglev trains based on optical fiber sensors is designed to improve the operation safety and stability of superconducting maglev trains.The system mainly includes:sensor system,data acquisition and transmission system,intelligent monitoring software system and power supply and distribution system.The monitoring system provides real-time and reliable continuous data monitoring,and the sensor data of each channel is calculated by the demodulator and uploaded to the server through the TCP protocol via the local area network.The server then uploads the data to the central control unit(CCU).The system has been tested and verified to realize data interaction,command sending,online monitoring and data reading of multiple servers,which provides technical support for reliable operation of HTS maglev train.
