【Abstract】 Rail transit is witnessing a profound transformation centered on automation and intelligence. As the core guarantee for operational safety and efficiency, the rail transit signaling system is also undergoing a fundamental shift in its technical architecture and implementation paradigm. Secure computing technology serves as a core enabler for the intelligent transformation of rail transit and guarantees the safety and efficiency of train operation. In particular, the cloud cloudbased safety-critical computing platform represents a critical approach to breaking through the development bottlenecks of traditional signaling systems. Against this backdrop, this paper conducts an in-depth analysis of the global development trends in this technical field, reveals the evolution laws of information-enabling technologies and signaling innovation technologies, and discusses the requirement characteristics, architectural design and the key technologies of the cloud-based safetycritical platform for train operation control computing platforms in the intelligent era. Currently, feasibility studies on cloud-based safety-critical computing platforms have been carried out in multiple domestic and international projects. This paper provides a technical reference for the cloudbased transformation of rail transit signaling systems and facilitates the development of the industry toward greater intelligence, efficiency, and safety.更多还原
