摘　　要：面向机载武器系统的仿真测试,建立总线通信仿真测试平台,研制ARINC 429总线通信智能模块。针对机载武器系统中基于数据帧的总线通信方式,提出了缓冲区资源自动配置算法及其实现方案。在通信过程中根据各信道数据帧的特征和信道流量统计信息,动态分配信道缓冲,提高存储空间利用率,减少丢帧。To meet the requierments of simulation and automatic testing of airborne weapon system,a type of multi-channel smart ARINC 429 communication module is developed.A resource self-orgniazation algorithm is proposed and implemented in the management of communication buffer.Buffer space can be re-allocated for each 429 channel dynamically based on frame size and channel flow.A better buffer utilization can be achived in case that flow differences exists in multi channles,and data lose can be avoided in frame surges.
