Urban traffic intelligent management and control system and method based on power line carrier

Abstract

The invention discloses an urban traffic intelligent management and control system and method based on a power line carrier. The system comprises an image acquisition module, a voice calling module, atraffic signal lamp, a carrier communication module, a master station server and a master station monitoring terminal. According to the system, the image information of the intersection is acquired and transmitted to the main station by using the carrier signal, the state of the traffic signal lamp of the intersection or other intersections can be controlled by the main station monitoring terminal, vehicles and pedestrians can be guided by the traffic signal lamp, in case of emergency, on-site personnel can also send out voice help through the voice calling module, voice help information is also transmitted to the main station through the carrier signal, the main station can know the on-site condition through the voice content recognition result, the state of the signal lamp is adjusted in time to carry out vehicle retention and personnel evacuation, and the traffic management and control efficiency is greatly improved.

Description

technical field [0001] The present invention relates to the technical field of carrier communication and traffic control, and more specifically relates to an intelligent control system and method for urban traffic based on power line carrier. Background technique [0002] At present, with the continuous development of the economy, the number of private cars has increased significantly, and the problems of traffic jams and frequent accidents have become increasingly prominent, especially during the rush hour. The accident caused traffic to be stranded, further aggravating traffic congestion. For this reason, most cities use traffic police to assist road traffic flow during the peak period of traffic flow. However, this artificial traffic supervision method not only needs a lot of manpower and material resources, but also cannot guide the rear vehicles to detour in time when an emergency occurs. It is still easy to have serious vehicle retention problems, and the traffic cont...

Problems solved by technology

[0004] In view of this, the present invention provides a power line carrier-based urban traffic intelligent management and control system and method. The system is based on the image information at the intersection and the voice help information of the on-site personnel, and uses the carrier signal to transmit to the main station, and monitor the traffic through the main station. The terminal can control the status of traffic lights at this intersection or other intersections, and guide vehicles and pedestrians in a timely manner through traffic lights, which solves the problem that the existing traffic control methods are not smart enough, convenient, and difficult to guarantee efficiency
