Application Design and Performance Evaluation of the JD-1A Computer-Based Interlocking System in Russian Railway Stations

With the rapid development of urban rail transit, higher requirements have been raised for the safety and reliability of computer-based interlocking technology. As a key component of the train operation control and command automation system, the computer interlocking system integrates advanced communication and computer technologies. It plays an important role in improving transport efficiency and ensuring operational safety. Based on an analysis of the current application status of computer interlocking systems, this study takes the JD-1A computer interlocking control system for railway stations as the research object. Using a Russian railway station as a case, the safety and reliability of the system are designed and analyzed. The main work includes: discussing the principles and development status of computer interlocking control systems, designing a station scheme based on the JD-1A system, evaluating the economic indicators of its implementation at the station, and analyzing workplace lighting safety and its influence within the system framework.
