为了保证飞机作战任务信息传输和传递的准确性和安全性,并考虑数据加载的方便快捷,文章提出了一种采用DSP实现安全可靠加载任务数据的解决方案。设计方案采用USB标准线性FLASH存储卡作为任务数据加密存储和传递载体,在飞机座舱操纵台安装一个集成USB存储卡,集数据读取解密和1553B总线数据加载等功能为一体的作战任务加载器。文章从应用需求出发,对加载器的软硬件设计与实现方法进行了较为详尽的描述。此作战任务加载器的应用丰富了任务数据的加载方式,减少了飞行员的操作,并能保证作战任务数据的可靠传输。
In order to ensure the accuracy and security of the information transmission and transmission of aircraft combat missions and to consider the convenience and speed of data loading, a solution to load mission data safely and reliably using DSP is proposed. The design adopts the USB standard linear FLASH memory card as mission data encryption storage and delivery carrier, and installs an integrated USB memory card in the aircraft cockpit console and integrates functions such as data read and decryption and 1553B bus data loading. Based on the application requirements, the article describes the software and hardware design and implementation of the loader in more detail. The application of this warfare task loader enriches the loading of mission data, reduces the pilot’s operations and ensures the reliable transmission of combat mission data.
