Crossroad intelligent traffic light network control system capable of handling emergent event

Abstract

The invention provides a crossroad intelligent traffic light network control system capable of handling an emergent event. The crossroad intelligent traffic light network control system includes a supersonic wave detection module, a microwave detection module, a control module and a traffic light module. By means of IoT technology, an IoT network operation system schedules and manages to form the detection equipment and the traffic light time of a traffic light IoT network system, so that the emergent event of the crossroad can be responded in real time, the combined detection and networking processing can be realized, and the aim of intelligent traffic light control can be achieved. Through a series of traffic management and service systems such as traffic signal control, travel induction, and bus information services, the rational distribution of traffic flow can be guided, the dynamic organization and management of urban traffic can be realized, the efficiency of traffic operation is improved, and the smooth and orderly city is guaranteed.

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 t...

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
