摘要/Abstract

摘要： 为了实现指控系统中雷达数据的可靠传输，采用面向比特的链路层协议HDLC实现数据通信。以CPCI总线为基础架构，采用FPGA技术实现HDLC协议控制器，完成CPCI本地数据读写模块、HDLC协议帧的构成、解析模块及其内部的CRC码生成、检验模块。对通信卡进行专门的板极加固设计，使其适用于军用环境中。实验结果表明，在军用恶劣环境中，板卡可以按照标准的HDLC帧格式收发数据，稳定可靠。

Abstract: In order to achieve reliable data transmission for radars in Command and Control System, bit-oriented data link layer protocol HDLC was used for communications. Based on CPCI architecture, FPGA technology was adopted to achieve HDLC protocol controller. CPCI data reading and writing module for local bus, HDLC frame composition and analysis module, CRC code generation and verification module were all achieved. A special board-level reinforcement design is prepared for the card to adapt to military environments. Experiments show that the board can receive and send frames according to the standard data format of HDLC in harsh military environment stably and reliably.
