Application of electrical automation in rail transit signal system

Abstract As a key technology to ensure the safety and efficiency of train operation, the performance and reliability of railway traffic signaling systems have a decisive impact on the overall operation of the railway transportation system. Traditional signaling systems use circuit relays or computer interlocking technology, which has problems such as a limited degree of automation and difficult fault diagnosis. With the rapid development of electrical automation technology, its application in railway traffic signal systems has become a hot spot in the current industry research. This paper discusses the current application status, advantages, and future development trends of electrical automation technology in railway traffic signaling systems, aiming to provide reference and practical guidance for building a more intelligent and efficient railway traffic signaling system. The application of electrical automation technology not only significantly improves the automation level of the signal system, but also enhances the reliability and safety of the system through intelligent monitoring and precise control, and injects new vitality into the sustainable development of railway transportation.
