Cloud-Based Simulated Automated Testing Platform for Virtual Coupling System

Research on virtual coupling has made further progress. It needs many tests before operation. The problem of connecting the new railway with the existing railway will arise. The increasingly large and complex hubs make a test of virtual coupling difficult. Test of the virtual coupling system, especially combined test, has a heavy workload. Restricted by time and the influence of the existing transportation, it is challenging to discover defects and hidden dangers of virtual coupling systems through dynamic on-site test procedures. The laboratory "full scene, full elements" engineering testing urgently needs to be executed before the opening of new lines. Limited to supply of real equipment, we proposed a semi-physical and semisimulation testing scheme. The virtualization transplantation of real equipment is one of the main challenges to realizing simulated testing. A cloud-based platform is designed to carry the simulated testing environment. Thus, most of the work that depends on dynamic on-site testing can be replaced by simulated testing. It can reduce the dynamic testing cost of the signal system and its impact on transportation. The advantages of simulated testing technologies can also effectively improve the quality, depth, and breadth of virtual coupling system testing.
