This paper addresses the challenges in onsite engineering acceptance testing of urban rail transit signaling systems in China, which currently face issues such as singlemethod approaches, lengthy cycle times, low efficiency, high costs, and heavy workloads. A method for automatic generation of onsite engineering acceptance test sequences is proposed. The methodology involves three main steps: First, analyzing the constraints of interconnection test case sets for urban rail signal systems; second, dividing the line into independent test sections; and third, converting line characteristics into computerrecognizable formal language to enhance editing efficiency and humancomputer interaction. The proposed method employs an “auxiliary generation tool" to automatically generate fieldexecutable engineering acceptance test sequences. The effectiveness of this approach is validated through tests on actual railway lines. Results demonstrate that test sequences designed using formal language meet engineering acceptance requirements, achieve 100% coverage of interconnection test cases, and significantly reduce field testing time while improving efficiency compared to traditional manual test sequence design methods.
