基于ARINC429接口板的嵌入式底层软件测试平台设计

摘要

为满足底层软件的使用需求及减少其存在覆盖率低、消耗成本大、丢包率高、数据采集频率小等问题,提出并设计了基于ARINC429接口板的嵌入式底层软件测试平台;根据 ARINC429接口板的结构框图能够设计出嵌入式底层软件测试平台,针对用户安全登录问题,设计了平台登录验证功能;通过对嵌入式底层软件运行信息显示,能够实时对软件运行状态进行监测,进而为数据采集与查询提供支持;设计工具链作为代码编译开发和结构测试工具;通过数据采集、处理、传输来完善软件测试平台的覆盖率;通过实验对比分析可知,该测试平台能够提高测试覆盖率,降低丢包率,促使数据采集频率大大增强,为软件测试平台的安全有效运行提供了保障.%In order to meet the demand and use of software to reduce the presence of low coverage,high cost,high packet loss rate,data acquisition frequency,proposed and designed the embedded ARINC429 interface board software testing platform based on.According to the structure diagram of ARINC429 interface board to design embedded software testing platform for user login security,design platform login authentication function;through the display of the embedded software running information,real-time monitoring of the running state of the software,so as to provide data acquisition and query support;design tool chain as code development and the structure of test tools;to im-prove software testing platform coverage through data acquisition,processing and transmission.Through the comparative analysis of the ex-periment,we can see that the test platform can improve test coverage,reduce packet loss rate,greatly increase the frequency of data acquisi-tion,and provide a guarantee for the safe and effective operation of software testing platform.
