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.
