Intelligent Traffic Light Network Control System at Intersections That Can Handle Emergencies

Abstract

The present invention provides an intelligent traffic light network control system at a crossroad that can handle emergencies, including an ultrasonic detection module, a microwave detection module, a control module and a traffic light module. The present invention adopts the "Internet of Things network operating system" with the help of the Internet of Things technology To schedule and manage the detection equipment and traffic light time that constitute the traffic light Internet of Things network system, respond to emergencies at traffic intersections in real time, realize joint detection, network processing, and achieve the purpose of intelligent traffic light control. Through a series of traffic management and service systems such as traffic signal control, travel guidance, and bus information services, it can guide the reasonable distribution of traffic flow, realize the dynamic organization and management of urban traffic, improve the efficiency of traffic operation, and ensure the smooth and orderly flow of the city.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to an intelligent traffic light network control system at a crossroad that can handle emergencies. Background technique [0002] Traffic lights have a history of more than 150 years. From the original use of kerosene lamps and artificial pull ropes to control the conversion of traffic lights, to estimate the traffic flow at intersections, calculate the time in advance, and change regularly to ensure traffic safety at intersections. With the wide application of computer technology, monitoring technology and satellite positioning technology, the calculation method of fuzzy mathematics has also begun to be adopted by the traffic light control system. The changing time of traffic lights at major intersections in big cities can be measured by comparing and measuring the queue length of vehicles to determine the changes in the actual flow of vehicles and determine the length of time ...

Problems solved by technology

[0010] At present, the size of various sensors has been greatly reduced, and the size and price of a large number of intelligent processing components have also been greatly reduced. This trend ensures that traffic light sensing and intelligent processing components can be miniaturized and low-priced, but At present, the traffic light system of ITS must be constructed through a network architecture due to its discrete structure, and the long-distance reliable information transmission increases the difficulty of system composition, and the real-time network response, scheduling and management for real-time emergencies is an intelligent traffic light system. Insurmountable difficulties, resulting in high costs and high prices, have become the technical root that hinders the promotion and application of smart traffic lights

[0011] The network structure of the intelligent traffic light system: Usually, the traffic lights are controlled regularly by a single processor based on estimating the traffic flow at each intersection, and the method of controlling the traffic lights by detecting the flow is often affected by the installation environment, working environment, and composition environment of the detection equipment. , Dealing with different environments, it is difficult to provide an intelligent working mode
