摘　　要：该文提出一种用于航空机载智能接触器系统的通用自动测试平台设计方法。系统上位机使用LabVIEW软件,完成对总线协议的解码分析与功能验证工作;平台系统主要通过上位机将需要测试的指令通过RS485接口发送到自动测试平台以后,经过下位机测试平台ARM进行协议解析,根据解析内容完成相关接口功能的测试工作,并将结果自动反馈到上位机进行自动判别处理,系统可同时批量验证十套产品的验证工作。另外,该自动测试平台还具备对产品的IAP升级功能,只需要外接CAN接口即可完成,可以极大地增加测试系统设计的灵活性和实用,该方法简单、便捷和可靠,具有一定的使用价值。This article proposes the design method of automatic test platforms that can provide testing in the aviation system.The system upper machine software is developed using LabVIEW,which completes the decoding analysis and functional verification of the system bus protocol.The system mainly uses the instructions to test the instructions to be tested through the RS485 interface to the automatic test platform.The protocol analysis completes the test work of the relevant interface function based on the analysis content,and automatically feeds the result to the upper machine for automatic discrimination processing.In addition,the automatic testing platform also has the IAP upgrade function of the product.It can be completed by only external CAN interfaces,which can greatly increase the flexibility and practicality of the design of the test system.
