Safety Computer Simulation System Based on Sensor Models

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.
