摘要: 在安全计算机信号系统的研发与测试中,没有真实的传感器接入会带来测试难、验证难等问题。为此,设计一种基于传感器模型的轨道交通安全计算机平台仿真系统。以真实的传感器为模型基础进行传感器建模,控制真实的硬件输出,通过软硬件结合的方法为安全计算机平台提供真实的输入与输出。同时利用软件修改模型参数,模拟传感器故障,为安全计算机平台提供无损坏的故障注入。测试结果证明,该仿真系统能够有效验证安全计算机平台的安全性、可靠性与可用性,加快安全计算机平台的开发进程。

Abstract: In order to overcome the verification and test difficulties caused by the absence of sensors when developing safety computer systems, a model-based simulation system for safety computer system is presented. Modeling on real sensors to control real hardware, by the method of combination of hardware and software, the simulation system provides actual physical input and output signals for safety computer system. At the same time, by modifying the model parameters, it can provide no damage fault injection for safety computer systems. The test results show that the simulation system can effectively verify the security, reliability and availability of safety computer systems and can speed up the development process of safety computer systems.

Key words: simulation system, safety computer system, sensor modeling, no damage fault injection, system modeling, rail transit
