Research and Implementation of Simulation Testing Technology for Train Control System Based on Satellite Positioning

In this study on satellite-based train control systems, the data structure of electronic maps was analyzed. Moreover, a semi-physical simulation system for laboratory system integration testing was designed and implemented. By parsing and computing electronic maps and combining them with train control engineering data, the proposed design swiftly constructs a system integration testing environment, improves the real-time calculation efficiency of satellite simulation data, supports the testing and verification of the functions and data of satellite-based train control systems, and provides agile and powerful technical support for equipment development and laboratory testing. The design’s viability was confirmed via system deployment and laboratory tests in an engineering project, fulfilling the laboratory testing criteria.
