Analysis of the Interface between Urban Rail Transit Signaling System and Platform Screen Door System

Journal Title: Urban Mass Transit - Year 2024, Vol 27, Issue 11

Abstract

Objective The control of PSD (platform screen doors) by signaling system is crucial for ensuring urban rail transit stable operation. The interface between the signaling system and the PSD system is equally important for the stable and efficient control of PSD. Therefore, it is necessary to conduct an in-depth analysis of this interface, comparing traditional relay interfaces with the new type of PSDC (platform screen door control) system interface, and to analyze the scheme of PSD direct control using PSDC interface. Method A detailed analysis of the system architecture using relay interfaces versus PSDC interface is provided. These interfaces are compared from equipment structure, information exchange, equipment maintenance, and operation-maintenance support perspectives. Based on the interface structures, the scheme of PSD direct control using PSDC interface is discussed. Result & Conclusion Compared to the relay interface, PSDC interface features faster communication speed, better security, and shorter information exchange process, presenting a comprehensive and intuitive display of equipment status and parameter changes with obvious advantages. The above-mentioned scheme reduces the need for intermediate devices to transmit the command and non-command information, facilitating centralized monitoring and management, and thereby enhancing operational efficiency.
