摘　　要：余度技术是提高可靠性的有效途径,余度系统同步是余度技术的关键。在SCADE开发环境中采用图形化建模方式搭建三余度飞控计算机任务同步模型,应用自动代码生成技术将任务同步模型生成高可靠嵌入式实时代码,省略代码单元测试,具有开发周期短、安全性高等优点。在实际应用中能稳定可靠的完成了任务同步,为余度系统作用发挥奠定了基础。The technology of Hot- redundancy is an effective approach to improve the security of system. Synchronization is the key of the Hot- redundancy system. Based on SCADE, applying the graphical modeling way developed task synchronization, and generated reliable real- time embedded code automatically without cell test, with the advantages of short period and high security, the system has also been tested and put into practical use. Synchronization of Triplex Hot - redundancy Flight control computer plays a very important part in carrying out the Hot- redundancy system＇s role.
