摘　　要：HDLC协议以其优异的性能在可靠性需求较高的场合得到了广泛应用.针对航天某领域的协议测试评估需求,解决传统协议测试设备程序复杂、开发周期长的问题.为了满足系统快速集成、协议参数灵活配置的总体要求,提出了一种基于LabVIEW软件构建HDLC协议收发器的方案,完成了HDLC核心收发模块设计,并以此为基础组成一套完整的测试系统.对HDLC协议处理及接收、发送程序设计进行了说明,着重介绍了收发器中核心循环校验码(CRC)校验模块及比特插入删除模块的实现方法,同时对收发器的主要功能模块进行了仿真和测试.使用LabVIEW设计的HDLC收发器轻量高效、运行灵活,可应用于HDLC协议设备的测试和协议性能分析等场合,提高数据通信系统的扩展性、实时性和稳定性.Traditional protocols are perplexed by complex testing equipment and long development cycle,thus are not appropriate for protocol testing and evaluation in a certain field of aerospace.The HDLC protocol has been widely used in applications demanding of high reliability because of its excellent performance.Here,we propose a scheme to build HDLC protocol transceiver based on LabVIEW software,with the aim of rapid system integration and flexible configuration of protocol parameters.The HDLC core transceiver module is designed,on which a complete test system is formed.This paper introduces the HDLC protocol processing as well as the program design of receiving and sending,and elaborates the realization of the Cyclic Redundancy Check(CRC)module and the bit insert&delete module in the transceiver.Meanwhile,the main function modules of the transceiver are simulated and tested.The results show that the proposed HDLC transceiver is light in weight,efficient and flexible in operation.It can be applied to scenarios such as the testing of HDLC protocol equipment and protocol performance analysis to improve the data communication system in scalability,real-time performance and stability.
