一体化1553B总线通信仿真平台设计与实现

Design and realization of integrated 1553B communication simulation platform

1553B总线通信原理对于学习航空电子系统具有重大意义,为实现1553B总线消息格式、通信过程的可视化演示和定量分析,设计了一体化架构1553B总线仿真平台,帮助学员更直观地理解1553B总线的通信过程。平台基于HKS1553BCRT芯片的ARM7内核,在同一程序框架下设计并实现了编码实验、原理实验到综合实验的验证性实验,同时为学员进行设计性实验提供硬件支持和软件接口。实际应用中,该平台有较高的稳定性、准确性和可操作性,成功应用到《机载总线网络》课程教学中。

The communication principle of 1553B bus is of great significance for learning avionics system.In order to realize the visual demonstration and quantitative analysis of 1553B bus message format and communication process,an integrated architecture 1553B bus simulation platform is designed to help students understand the communication process of 1553B bus more intuitionately.Based on the ARM7 kernel of HKS1553BCRT chip,the platform designs and implements the verification experiment of coding experiment,principle experiment and comprehensive experiment under the same programming framework,and provides hardware support and software interface for students to carry out design experiment at the same time.In practical application,the platform has high stability,accuracy and maneuverability,and has been successfully applied to the teaching of airborne bus network.
