规则驱动的联锁系统自动测试研究与实现

Research and development on rulers driver automation for railway signaling interlocking system

计算机联锁系统是轨道交通系统中对安全性和可靠性要求极高的关键子系统,长期以来,联锁系统测试存在数据量大和测试难以全覆盖的问题。针对该问题,提出一种规则驱动的自动测试平台,首次把专家经验融入到自动测试中,可以基于规则自动生成测试脚本并自动执行,用例可全覆盖被测试设备,从而对数据进行完备测试。将该平台应用到某地铁正线和车辆段联锁系统中,测试结果表明,该平台特别适用于中型和大型站场测试,并且极易拓展到其他安全系统的测试中。

Computer interlocking system is a key subsystem of railway transportation system that requires high safety and reliability.For a long time,fully covering the test of railway signal interlocking system was difficult because of the large amount of data.This paper focuses the research and development on a rule-driven automated platform that integrates expert experience into automatic testing and can generate test scripts based on rules to cover all signal devices.It canalso protract track map and perform scripts in a single batch.Test results against an interlocking system of a special line show that the platform is especially suitable for medium-and large-scale station testing,and can be easily extended to the testing of other security systems.
