Objective In the construction and renovation of urban rail transit safety inspection and detection systems, there exist problems such as unclear applicability of relevant standards and insufficient basis for technology selection. To address this and to provide standardized solutions for the configuration, selection, and quality control of safety inspection and detection equipment and systems, it is necessary to clarify the key implementation points of "Safety Inspection and Detection Systems", Chapter 10 in the new version of GB/T 26718-2024 Technical Requirements for Safety System of Urban Mass Transit.

Method The technical standards and implementation requirements for urban rail transit safety inspection and detection systems are the focus of the research. By comparing with the old version of GB/T 26718—2011 and considering industry demands as well, the revision principles of the "safety Inspection and Detection Systems" chapter in GB/T 26718-2024, and the key revisions in areas such as equipment classification, technical parameters, and intelligent functions are analyzed The critical technical indicators for equipment such as explosive detectors, liquid hazardous material detectors, X-ray safety inspection systems, human body safety scanners, and biological agent detectors, along with the connotation and practical significance of relevant provisions are specifically examined and discussed.

Result & Conclusion  In addition to structural changes, the new version GB/T 26718-2024 expands the detectable categories of safety inspection and detection systems, introduces new technological methods, and proposes performance indicators of the equipment suitable for urban rail transit applications while balancing safety and cost-effectiveness. It particularly enhances technical requirements for intelligent recognition, networked interoperability, and unified data interfaces. The effective implementation of new version GB/T 26718-2024 requires moving beyond the mindset of single-equipment procurement and turning to an integrated approach that incorporates system integration and scenario adaptation.
