A Speed and Positioning Verification Facility (SPVF) system was developed to conduct cooperative detection of speed and positioning systems and to verify the functionality of high-speed maglev trains. Based on hardware-in-the-loop (HIL) simulation technology, a dynamic simulation model of a maglev train, a peripheral environment simulation model of operation and control, the speed and position system, and wireless communication equipment were integrated by a real-time simulation computer. This article introduces a train motion simulation module, a line track module, and a traction power supply system simulation module. These modules can simulate the motion status of high-speed maglev trains and the process of collecting train positioning information. A data transmission channel has been established to facilitate the data transmission of onboard safety computers, partition security computers, traction control units, and speed and positioning measurement units. The experimental application of the project has proven that the system can provide a comprehensive and effective testing and verification environment for the speed and position detection of high-speed maglev trains.
