As the core of guaranteeing the safety of high-speed railway traffics and improving transportation efficiency, Chinese Train Control System (CTCS) is the nerve center of railway transportation. As the key component of the CTCS, the on-board equipment is of great significance to diagnose its fault location quickly and effectively. At present, the fault diagnosis method based on artificial intelligence...
The fault diagnosis and analysis of high-speed train is of great significance for train's safe and highly efficient operation. The complexity and quantity of on-train information which is closely related with fault diagnosis and analysis is increasing rapidly as the development of high-speed railway. Onboard system fault recording files contains lots of important fault information described in short-text...
T rain-ground communication subsystem is a key subsystem in high-speed train control system and plays an important role during the operation of high-speed train. So the reliability of train-ground communication subsystem should be studied in depth. The dynamic fault tree model for train-ground communication subsystem that is modeled based on the structure chart of the subsystem is transformed to Dynamic...
Cooperative Intersection Collision Avoidance System (CICAS) program uses roadside radar sensors, a computer processor and algorithms to determine unsafe conditions, and an active LED icon based sign to provide timely alerts and warnings which are designed to reduce the frequency of crashes at rural expressway intersections. The cooperative component of the CICAS system consists of roadside equipment...
Train Location information is important for train control system. As for the train locating using GNSS technology, validation of location data is important. The railway yard has to be traversed several times in data validation process. Computer simulation technology is used to simulate yard-traversing repeatedly for some difficult situations. A new optimal continuous traversal algorithm is proposed...
