| 摘 要： | 在安全攸关的控制系统中通信或计算机出错的情况下,所有无错的部件必须保证传送的数据是一致的.为解决这一问题,需要专门的算法.本文介绍了总线通信时的签名消息算法,以分布式冗余刹车控制系统为例,讨论了算法的实现,并讨论了CAN在签名消息算法中应用的可能性.

| Abstract: | In safety critical control systems, data transferred among its individual parts should be consistent for all non faulty parts, even when there are possible disturbances or faults. To satisfy this requirement, dedicated algorithm is needed. This paper explains the principle of Signed Message Algorithm and its implementation in distributed redundant brake-by-wire application. The feasibility of using CAN in this system is discussed. |
