摘　　要：针对多种数据链之间标准不统一、交互困难的问题,在开放式系统互联(OSI)模型的基础上,提出一种数据链的通用模型。分析Link-16数据链的消息标准、时隙分配方式和通信协议,使用通用模型对Link-16数据链进行建模;通过研究Link-16数据链工作过程中的入网技术、同步技术、时隙接入技术和网络成员之间微小时间差的捕获技术,给出Link-16数据链端机的同步原理和入网方法;结合Link-16数据链的具体相关参数,给出通用模型的物理层和链路层的具体实现方法。To unify the standards between different data links and to interact conveniently,a hierarchical Link-16 model based on the open system interconnection（OSI）model was proposed.The Link-16 message standard,time slot assignment method and communication protocol were analyzed and the Link-16 was simulated using the general model.A study of the network technology,synchronization technology,time slot access technology and tiny time difference of network members were carried out and network access method and synchronization principle for Link-16 computer terminals were provided.Combined with specific parameters of Link-16,the realization algorithm of link layer and physical layer in the hierarchical model was put forward.
