本文提出了一种新的概念模型——xbw模型。分布式计算正在成为实现安全关键控制系统的一种经济有效的方式。为了支持此类系统的开发，开发了XBW概念模型。该模型描述了系统的时间行为和分布特性，从而可以应用静态调度和系统容错。概念模型还支持定义适当的故障模型。这种故障模型以及xbw模型允许有效和系统地使用众所周知的基于软件的错误检测方法。根据该模型开发了分布式线控转向控制系统。xbw模型是在欧洲Brite-EuRam III项目X-By-Wire中开发的。
This paper presents a new conceptual model, the XBW-model. Distributed computing is becoming a cost effective way to implement safety critical control systems. To support the development of such systems the XBW conceptual model was developed. The model describes the time behavior and distribution properties of a system in such a way that static scheduling and systematic fault tolerance can be applied. The conceptual model also enables the definition of an appropriate fault model. This fault model along with the XBW-model allow efficient and systematic use of well known software based error detection methods. A distributed steer-by-wire control system is described, which is developed according to the model. The XBW-model is developed within in the European Brite-EuRam III project X-By-Wire.
