一种1553B总线接口模块测试设备的设计与实现

Design and Realization of Test Equipment for 1553B Bus Interface Module

随着1553B总线在航空领域的大规模应用,低成本、高效率的接口模块测试验证尤为重要。本文设计并实现了基于串行总线架构的通用1553B总线接口模块测试设备,通过将CPU外置并通过串行总线与测试工装连接,在测试工装内实现串行总线接口到并行总线接口的协议转换,具有通货量大、成本低、简单易用的特点。长时间应用验证表明,该设计能够满足1553B总线接口模块试验条件要求,对其他同类型接口模块测试设备研制具有一定的参考价值。

With the widespread application of 1553B bus in the aviation, low-cost and effective testing technology of the interface module is particularly important. In this paper, a kind of general 1553B testing equipment based serial bus architecture is designed. It realized the protocol conversion of serial bus interface to 1553B bus interface with the CPU outsiding and connecting with the testing equipment by the serial bus. It has low-cost and easy to used features. The long time application and testing resuits show that the design satisfy the testing requirement of 1553B bus interface module. It has a certain reference value for the design of other similar interface module testing.
