摘要
安全平台是保障铁路信号系统安全运行的关键设备。采用黑盒测试方法,对安全平台对外通信的丢包率等指标进行测试,形成安全平台通信性能测试系统。测试可自动执行,无需人工干预。测试结果在界面中实时呈现,作为判定产品是否合格的依据,并达到控制产品质量、及时发现问题的目的。
Safety platform plays a key role in safeguarding safety operation of railway signal system.Black box test is performed to testing packet loss rate and other indexes during external communication,and safety platform integrated test system is formed.Tests are automatically executed without manual interference.Test results are presented in the interface in real time,which can be used to judge whether this product is qualifi ed,control product quality and fi nd out defi ciency timely.
