Abstract

Track circuit signal equipment is the “nerve center” of railway transportation, and its operation directly affects safety and efficiency. With the development of railways, equipment failures are frequent and diverse. It is of great significance to conduct in-depth research on fault diagnosis techniques and establish a preventive maintenance system. This article analyzes the causes and troubleshooting points of equipment failures, introduces intelligent monitoring, fault diagnosis algorithms, remote troubleshooting, and standardized upgrading of specialized troubleshooting tools required for typical systems such as 25Hz track circuit overlay ZPW2000 coding equipment and ZPW2000 track circuit. It elaborates on the practical path of constructing a preventive maintenance system, including scientifically formulating maintenance plans, controlling daily inspection content, implementing component cycle maintenance standards, and improving the professional abilities of maintenance personnel, providing support for the safe and stable operation of railway transportation.
