Design and implementation of dynamic characteristics tracking system of maglev train based on real-time target and communication interface

The dynamic characteristics tracking system of maglev train gets speed curve and current position of the maglev train by monitoring and calculating data from traction linear motor system to ensure the maglev train be safe under any circumstances. The key to solve this problem is to make sure the system has high performance of communication and real-time computing ability. This paper gives a novel design of hardware and software implementation of the dynamic characteristics tracking system. The hardware solutions include FPGA execution device, UDP and RS485 communication interface. The software platform is finished under LabVIEW environment. It is proved that the calculation and communication of the whole system is completion within 3ms. The experimental results shows that the whole system meet requirements of real-time, stability and reliability.
