In response to issues such as complex wiring in traditional platform screen door control systems, difficulties in daily maintenance of relays, challenges in troubleshooting, and cumbersome intermediate transmission links in interactions with signaling systems, this paper proposes a platform screen door controller (PSDC) solution. This solution employs SIL4-level safety technology based on domestically developed hardware and software, along with a “fail-safe” all-electronic single-board technology, achieving a fully electronic design for the platform screen door controller. By integrating computer and network technologies, the solution realizes the integration and digitalization of interfaces between the signaling system and the platform screen door system. Comparative analysis between the traditional platform screen door control system and the proposed solution in terms of system architecture, control links, and engineering implementation reveals that the fully electronic design of the platform screen door controller features a simpler overall architecture, real-time fault detection and alarm capabilities, and eliminates inherent safety hazards associated with relay-based control circuits, significantly enhancing system safety, reliability, and availability. The proposed solution not only simplifies the debugging process for the coordinated operation of train doors and platform screen doors but also significantly reduces the information exchange time for onboard train door opening/closing upon station arrival by approximately 4 seconds, thereby improving the operational efficiency and headway of the entire line. The research findings can serve as a reference for the development of multi-dimensional integration in urban rail transit.
