Network control system for traffic induction outdoor screen

Abstract

The invention provides a networking control system of traffic inducing outdoor screens. The distributed Ethernet is used as the fundamental architecture of the system, and a monitoring center is set; sections to which the traffic inducing outdoor screens belong are divided according to urban administrative regions, and the outdoor screens in the sections are controlled by monitoring sub-centers, are not interfered by one another, and are coordinated through an exchange server to construct the unified network control system. Control policies provided by the invention comprise a data processingpolicy and a display policy for issuing information. The invention provides an addressing module based on performance analysis and provides an assessment indicator system and a module solving algorithm based on a heuristic algorithm. The content of the invention relates to a plurality of key links, such as the architecture of the networking control system of the traffic inducing outdoor screens, the control policies, the addressing, and the like. The invention has the advantages of the completeness and the flexibility of the system architecture, the compatibility of data processing and the validity of the optimized addressing and improves the whole efficiency of constructing the networking control system of the traffic inducing outdoor screens.

Description

technical field [0001] The invention relates to the technical field of computer network control of traffic engineering, in particular to a networked control system of traffic induction outdoor screens. Background technique [0002] The present invention relates to three aspects of background technology, specifically, including: a system architecture based on a distributed Ethernet structure; an overall control strategy for traffic guidance outdoor screens, including data processing strategies and display strategies for releasing information; the third is outdoor screens The optimal location selection model. [0003] First of all, using distributed Ethernet to build a control network has become a commonly used integration method in the current control field, which has the advantages of rapidity, openness, compatibility and low cost. In the construction process of traffic monitoring system and traffic information release system, distributed Ethernet has also been fully applie...

AI Technical Summary

Problems solved by technology

[0005] Finally, the current control method of the outdoor screen system for traffic guidance mainly includes the collection, processing, and release of urban traffic data. The information transmitted to traffic travelers is current information, and the traffic forecast information for a period of time in the future cannot be notified to travelers. , therefore, the function of informing the traveler of the traffic status in the future period of time has not been realized
