Based on practical engineering application,this paper makes the in-depth analysis and study of the intel igent traffic identifica-tion technology,and then designs a set of gate machine control system based on DSP. The system is mainly composed of channel sensor module,master control module and gate control module. On this basis,it makes the channel sensor layout scheme design,hardware cir-cuit design and software design and builds the experiment platform,which is used to prove that the system meets the requirements.%从实际工程应用出发，对智能通行识别技术做了深入的分析和研究，设计了一套基于DSP的闸机控制系统。该系统主要由通道传感器模块、主控模块以及扇门控制模块组成，并以此进行了通道传感器布置方案设计、硬件电路设计以及软件设计。通过搭建实验平台，证明了该系统能够完成既定要求。
