Abstract: As urban rail transit expands rapidly, the operation and maintenance of metro signal systems are crucial. Traditional methods face challenges, like relying too much on manual work and not predicting faults well. This study uses Prognostics and Health Management (PHM) technology to create Nanning Metro Line 4's signal intelligent operation and maintenance system. By carefully analyzing requirements, it details the system's design, including its architecture and working principle. It also covers technical implementation, such as how to collect and process data, monitor equipment, predict faults, and make maintenance decisions. The goal is to boost the operation and maintenance levels and efficiency, guarantee metro safety, and offer a model for other urban rail transit signal intelligent operation and maintenance projects.
