Research on Automatic Test Method of Computer-Based Interlocking System

With the rapid development of China's high-speed railway, the scale and complexity of railway signal software are increasing, and efficient and sufficient testing has played an important role in improving software security and reducing railway safety accidents. As the core equipment of railway signal, computer-based interlocking system is mainly manual testing, which is inefficient and inadequate. In order to improve the safety of interlocking system, it is urgent to strengthen the research of testing technology and method. Therefore, after the research and analysis of computer-based interlocking system and its testing, this paper puts forward some improved testing methods and strategies of interlocking software, and designs the corresponding automatic test platform. We have carried out in-depth research on the functions of the platform, as well as the key technologies and difficulties of the platform construction, in order to improve the adequacy and accuracy of the testing, to improve the safety of the interlocking software, and thus ensure the safety of railway transportation.
