摘　　要：针对地空信息系统中地空设备交互通信的数据种类繁多、交互方式复杂多样的特点,对现有地面设备的对外I/O接口进行了简要介绍,基于接口数量有限的硬件限制,在原有的一对一数据通信的基础上,提出了一种多路数据自适应复接技术,根据各阶段传送的数据源的类型、速率和路数的不同,给出了具体实现方法,并进行了仿真。仿真结果表明,该技术自适应能力强、复接功能正常。经过实际系统测试,性能良好,满足系统设计要求。In view of varied communication data and interactive mode of interactive communication of ground-air information sys- tem,the external I/O interfaces of existing ground equipment is introduced briefly. Based on limited number of interface and inherent one-to-one data communication, this paper proposes a multi-channel data adaptive multiplexing technology, and provides typical imple- ment methods according to different data source type, data rate and quantity of channel in various phases.The simulation and analysis results show that this technology has high adaptability and normal multiplexing function. The practical test proves that it has better performance and can meet the requirement of system design.
