摘要
针对采用基于时间和空间分区的ARINC653软件架构中的设备加载端(任务加卸载设备)向应用软件(飞行管理软件维护分区)加载数据文件效率低速度慢的问题,文章通过改进设备加载端的时间延时、改进AFDX网络配置的数据包间隔时间、改进数据接收端的任务属性和主时间框架分配,实现了加载效率的有效提升。经过理论分析和实际测试,改进后的网络传输效率较之前提高3倍,满足了现阶段的系统需求。
Aiming at the problem of low efficiency and slow speed of loading data files into the application software(flight management software maintenance partition)in the device loading end(task loading and unloading equipment)in the ARINC653 software architecture based on time and space partitions,improves the loading efficiency by improving the time delay of the loading end of the device,the packet interval time of the AFDX network configuration,the task attributes of the data receiving end and the main time frame allocation.After theoretical analysis and actual testing,the improved network transmission efficiency is three times higher than before,meeting the current system requirements.
