摘　　要：为了提高计算机联锁系统的测试效率,缩短城轨工程项目的测试周期,文章提出了一种城市轨道交通信号系统联锁数据的自动化测试方法。该方法基于测试脚本,运用非编程语言描述测试脚本,无须通过修改联锁软件来增加通信接口即可实现对联锁软件的控制;通过数据驱动,借助联锁表、接口码位表等数据,自动生成测试脚本;在解析测试脚本后,向联锁系统发送控制命令,采集被测试设备状态并判断测试结果。此方法已在长沙市轨道交通2号线西延二期工程中应用,通过对比分析该项目自动化测试与人工测试的结果,发现自动化测试的总体缺陷识别率为85%,对联锁表数据缺陷的识别率达到100%,实际测试时间相较人工测试减少76%,验证了自动化测试的有效性,并显著提升了测试效率。To improve the testing efficiency of computer interlocking systems and shorten the testing cycle of urban rail transit projects,this paper proposes an automated testing method for interlocking data of signaling systems for urban rail transit.Built upon testing scripts,this method is devised to describe testing scripts using non-programming languages,allowing for the control of interlocking software without modifying the software itself or integrating additional communication interfaces.This data-driven approach automatically generates testing scripts,utilizing data such as interlocking tables and interface code tables.Following the parsing process of testing scripts,it enables the transmission of control commands to the interlocking system,state collection of tested devices,and determination of testing results.The proposed method has been applied in the construction of the west extension of Line 2(Phase II)in the Changsha Urban Rail Transit.Through comparing the results from automated and manual testing in this project,the automated testing approach exhibited an overall defect recognition rate of 85%,particularly a defect recognition rate of 100%for interlocking tables,and a decrease in actual time consumption of 76%in comparison with the manual mode,verifying the effectiveness of the method.This method has also contributed to a significant improvement in testing efficiency.
