Abstract:

The traditional intelligent control system for traffic congestion on narrow sections is poor in control ability, and the control effect is not obvious. In order to solve this problem, a new intellige nt control system for traffic congestion in narrow sections is designed based on Beidou satellite. The system hardware consists of a full range of magnetic sensors, a traffic dispatch controller, an empty circuit and A / D chip based on Beidou satellite. Adopt ASD CC_211 type data frequency acquisition chip for high-frequency wireless identification and collection of relevant information data such as traffic flow and narrow road sections, and apply specific frequency wireless network for remote information transmission. Apply FBR6-60 data identifier to compressed fusion data packets The data model is converted to realize the timely processing and analysis of data signals of traffic congestion. A / D analysis circuit board and D / A analysis circuit board generate certain high-frequency currents as pulse signals of intelligent systems for 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. In order to verify the effectiveness of the system, a comparative experiment was set up, and the results showed that the control capacity of the intelligent control system for traffic congestion in narrow sections based on Beidou satellites was increased by 25%.
