Overview of the Full Electronic Interlocking System

In recent years, the computer based-on interlocking system technology of various countries is developing to the full electronic interlocking system, so that the computer based-on interlocking system technology has an open structure, more small and intelligent. The full electronic interlocking system instead of signal and switch machine driven by relay with electronic execution unit has been widely used in European rail transit projects at present. Although it has not been widely used in China, there are also engineering application cases in many cities. Based on the existing interlocking system and reviewing the relevant literature, this paper describes the development process of the system and manufacturers, and then introduces the research status of the interlocking system, finally describes the problems to be solved in the computer interlocking system and its development prospect.
