说明：   本文对AIS基本结构、工作原理、技术特点、及其输入输出接口，输出信息的帧封装及解析原理等进行了解析。在此基础上完成了AIS信息采集处理的系统设计。
(This basic structure of the AIS, working principle, technical features, and its input and output interfaces, the output frame assembly and analysis of information theory, etc. were resolved. Based on this information to complete the AIS acquisition and processing system design.)
