Abstract: Railway signal circuits are used to control signal equipment to ensure driving safety and improve transportation efficiency with safety and reliability. However, in the actual use of relay circuit equipment, it is possible that the circuits fail to respond in a safe manner in the event of failure. This paper analyzes the potential unsafe factors in signal circuit design, conducts research and fault hypotheses, analyzes the risk factors of circuit design, eliminates loopholes and hidden dangers through checking and benchmarking, prevents problems before they occur, and ensures that the signal circuit design conforms to the "fail-safe" principle.
