摘　　要：针对航空平台传输信息多元化特点,提出了一种基于航空平台的多源数据处理系统。发送端将多任务多载荷输出的多源信息进行复接,实现对各路数据的透明传输。根据各路数据特性自动识别优先级,并在复接帧中为各路数据动态分配空间。接收端对复接数据进行解帧,还原各路数据。本系统通用性强、信道利用率高、具有智能化和可扩展性,目前已成功应用于多项国家863预研项目和无人机及飞艇等型号项目中。实际应用证明,本系统运行稳定可靠,适应性强,可适用不同类型载荷。Taking into account the diversified feature of information on the aerial platform, a multi-source data processing system was designed. The sender received multi-source data from different loads without frame format, and combined them into the multiplex frame. The system automatically determined the priority according to characteristics of multi-source data, and dynamically allocated space for multi-source data in the multiplex frame. The receiver decomposed the multiplex frame and retrieved multi-source data. The system has the versatility, high utilization, intelligent and scalable features. Now the system is successfully used in 863 programs, UAV （Unmanned Aerial Vehicle） and airship projects and so on. The practical application shows that the system can be commonly used for different types of loads and can be operated stably and reliably.
