Simplified Design of Embedded Double 2-vote-2 Computer System

摘要：

In this paper, a simplified design of double 2-vote-2 system is proposed, in which embedded system and redundancy CAN bus is adopted. In the system, the communication and switch between the subsystems are realized by CAN bus, and the double CPU communication of the subsystem is realized by dual-port RAM. The subsystems work in hot-standby mode. Theoretical calculation of reliability and security shows that the system meets the requirement of related standards of china. Comparing to other double 2-vote-2 systems, our system simplifies the hardware structure and holds lower cost.
