摘　　要： 文章介绍了专用短程通信 (dedicatedshort rangecommunications,DSRC)的研究现状 ,根据现有DSRC技术的标准 ,分析了其设备的硬件构成 ,论述了协议控制单元的系统结构和功能 ,进行了基于ADSP BF5 3 1的协议控制单元的硬件设计 ,探讨了DSRC技术的具体应用。 DSRC is a short-range communication system. As the communication platform for the vehicle and road,it integrates the vehicle and road organically by the duplex transport of information and helps Intelligent Transport System (ITS) to intelligently and dynamically manage the vehicle in real time. This article, at first, introduces the actuality of DSRC briefly based on the exiting DSRC technology standard, analyzes the composition of DSRC equipment and discusses the system makeup and function of the protocol control unit. Then it brings forward a hardware design for the protocol control unit of DSRC based on ADSP-BF531. At the same time, it also discusses the application of DSRC technology.
