摘　　要：当前狭窄路段交通拥堵智能控制系统存在控制能力差,控制效果不明显的问题;据此,设计了一种基于北斗卫星的狭窄路段交通拥堵智能控制系统;系统硬件设备由全方位磁传感器、交通调度控制器和基于北斗卫星的微控电路与A/D芯片组成;采用ASD CC211型号数据频率,采集狭窄路段车流量信息数据,应用频率无线网络传达远程信息,采用FBR6-60数据识别器对压缩融合数据包进行数据模型转换,通过A/D解析电路板、D/A解析电路板产生的高频电流作为脉冲信号,采用Dsk线路对脉冲信号进行放大增益,实现对狭窄路段交通拥堵的调控;根据硬件结构分别设计了综合性交通通信应用程序、空间信号智能控制程序、感应控制OHBD技术程序;通过对比该系统与传统系统的智能控制能力,实验结果表明,文章设计的基于北斗卫星的狭窄路段交通拥堵智能控制系统控制能力强,控制效果好。The current intelligent control system for traffic congestion on narrow sections has the problems of poor control ability and ineffective control effect.Based on this,this paper designs an intelligent control system for traffic congestion in narrow sections based on Beidou satellite.The system hardware equipment consists of a full range of magnetic sensors,a traffic dispatch controller,a micro-control circuit based on Beidou satellite,and an A/D chip.Adopt ASD CC211 model data frequency,collect traffic information data on narrow roads,apply frequency wireless network to communicate remote information,use FBR6-60 data identifier to perform data model conversion on compressed fusion data packets,analyze circuit board,D/A analyzes the high-frequency current generated by the circuit board as a pulse signal,and uses the Dsk line to amplify the pulse signal to achieve regulation of traffic congestion on narrow sections.According to the hardware structure,a comprehensive traffic communication application program,a space signal intelligent control program,and an induction control OHBD technology program are designed.By comparing the intelligent control capabilities of this system with traditional systems,the experimental results show that the intelligent control system for traffic congestion in narrow sections based on Beidou satellite designed in this paper has strong control ability and good control effect.
