摘要
根据AIS的通信协议,研究了采用高性能的DSP实现该协议的具体方法。详细介绍了基于DSP的AIS系统的组成,采用软件实现HDLC协议的CRC校验、数据组帧、解包,数据发送,数据接收,时隙分配与管理,UTC定时等的实现方法。系统调试结果表明这些实现技术可行。
According to the communication protocols of AIS( Automatic Identification System), the ways to implement the communication protocols by using high performance DSP(digital signal processor) are studied. The following are introduce in detail: the composition of the system, the software realization of the HDLC protocol which includes the checking of CRC code, packing and unpacking, the data transfer, the slots distribution and management, UTC timing etc. The results of debugging the system show that these approaches are feasible.
