自适应1553B总线通信功能系统级测试方法设计

Testing method research based on communication of self-adaptive 1553B bus

摘要:

一些通信卫星通过自适应1553B总线通讯，因此总线控制端在上电前对终端设备的内部遥测参数容量、存储位置是未知的，而是在系统上电后及运行期间动态地维护当前所有终端设备的状态信息，并由总线控制端通过对终端设备的轮询确定终端设备的总线接入状态，并动态获取终端设备的自描述信息，从而解决综合电子总线自适应性能单一、普适性差、数据动态交互机制弱的缺陷。针对某通信卫星自适应1553B总线通信功能，提出一种精准快捷的通信卫星1553B总线测试系统，通过1553B总线终端监视与处理设备，分别对1553B总线的自描述信息动态轮询获取功能和A/B总线自适应轮询功能进行测试，实现对自适应1553B总线实时监视与分析功能。实验表明，该测试系统有效验证了卫星1553B总线自适应通信功能，为总线通信的有效性和实时性提供保障。

Abstract:

A self-adaptive communication protocol was applied to a certain telecommunication satellite, the telemetry parameter capacity and storage location of remote terminal didn’t need to be pre-established in the bus control terminal. When on power, the information and bus status of remote terminal was transferred to bus control terminal dynamically, solving the problem of bad self-adaptive and poor universality of integrated electronic systems. In order to verify the communication function of self-adaptive 1553B bus based on certain telecommunication satellite, an accurate and efficient automatic testing system was proposed, and a bus monitor based on self-adaptive 1553B bus was applied. The results showed that compared with traditional communication protocol of 1553B bus, the proposed testing method validated the communication function based on self-adaptive 1553B bus was real-time, robust and efficient.
