高速铁路CTCS-3级系统功能测试必要性研究

Study on Necessity of Function Test of Chinese Train Control System Level 3(CTCS-3)

高速铁路CTCS-3级列控系统测试包括软件白盒测试(含静态测试、单元测试、集成测试)、产品功能测试和系统功能测试等阶段。目前,软件白盒测试、产品功能测试等方法已经广泛应用,但实践中通过了这些测试方法的CTCS-3级列控系统设备仍然存在一些问题。系统功能测试采用基于C3半实物仿真测试平台,验证CTCS-3级列控系统中的核心设备满足技术条件、系统需求和总体技术方案的功能要求。通过分析系统功能测试的内容和测试平台,根据实践中发现的各种场景、问题,分析系统功能测试的特点,研究高速铁路CTCS-3级系统功能测试必要性。

Function Test of CTCS-3 includes software white-box test,product function test and system function test.Software white-box test includes software static analysis,unit test and integration test.At present,the methods of software white-box test and product functional test are widely used;while there still exists some problems of CTCS-3 equipment.Function Test of CTCS-3 is based on hardin-loop test ensuring the core equipment to meet requirements of the technical conditions and overall technical scheme.The paper analyzes features of CTCS-3 function test and emphasizes the necessity of CTCS-3 function test,through test content and platform analysis,combining practical matters and actual problems.
