【Abstract】 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.更多还原
