Abstract
A real-time three-dimensional image monitoring platform for city traffic signal control relates to intelligent control management of the city traffic. The monitoring data of the monitoring platform derives from a road traffic controller at each road junction; each of the road traffic controllers is provided with a processing database server correspondingly. A wireless local-area network communication interface is positioned on the road traffic controller, a displaying terminal and the road traffic controller forms a monitoring network; the displaying terminal is a computer system established on an operating system in which a traffic parameter monitoring software protocol packet is stored. The traffic signal controller monitors the traffic parameters through a monitor on the controller, transmits the parameters to the respective processing database server through a piece of data communication equipment and completes data processing and the creation of dynamic scenes under control of a display program. The real-time three-dimensional dynamic display of the platform has non-direct view, animation and good effect. The real-time three-dimensional image monitoring platform also effectively utilizes the valuable resources of the existing city road traffic controllers, and prompts the level and progress of high-tech technology management of city modernization.

Background technology
Along with rapid economy development, urban population, motor vehicles, non power driven vehicle be all in quick increase, and the variation that how to make the management of traffic catch up with the numerous and complicated magnitude of traffic flow is the difficult problem that each city traffic management department needs to be resolved hurrily.In the current society of high-tech prosperity, modern ladder of management such as Based Intelligent Control have been introduced in traffic administration, and the on-line monitoring of real-time traffic flow becomes gerentocratic important tool.By the monitoring of real-time traffic flow, the vehicle of obstruction is effectively dredged in the energy scientific management, in time finds to prevent trouble before it happens potential safety hazard.The people's lives and property safety is played a very good protection.Yet, though increasing monitor supervision platform has been arranged now, generally being based on and finishing on the basis of electronic chart, monitored picture comprises buildings and other scenes.Directly extract the traffic detected parameters on the urban traffic signal controller, the monitor supervision platform that is made of monitored traffic real time 3-D image detected parameters yet there are no report.
Summary of the invention
The purpose of this invention is to provide a kind of on the urban road transportation control machine at the real time 3-D image monitoring platform for city traffic signals that directly extracts data, this platform can show intersection traffic signal control situation and situations such as vehicle, pedestrian's flow by the real-time online dynamic 3 D, in time carries out the traffic dynamic management according to multidate information.
The objective of the invention is to reach like this: a kind of real time 3-D image monitoring platform for city traffic signals, it is characterized in that: the detection data of described monitor supervision platform are taken from the road traffic controller at each crossing, each road traffic controller is to there being process database server separately, install Netcom of wireless office communication interface on the road traffic controller additional, display terminal and road traffic signal controller constitute monitor network.Display terminal is the computer system that is based upon on the WINDOWS operating system, storage DETECTION OF TRAFFIC PARAMETERS software protocol bag in the system.Detect traffic parameter by the detecting device on the road traffic signal controller at each crossing, and pass to process database server separately and upload to computer system by data communications equipment and carry out data processing, under display routine control, finish the establishment of data processing and dynamic scene at last, carry out dynamic 3 D by display terminal and show.
The working routine flow process of monitor supervision platform is: read the data of uploading of crossing controller, check whether to meet the communication standard data, not, return stressedly, be, write the corresponding intersection database, whether have new data, do not have if checking, return, and has, and refreshes demonstration.
The program circuit of display part is: display reading of data library information, create and show variable, new variables and old variable are compared, no change is arranged, if do not have, again reading of data library information, if change, carrying out variable resolves, variable is resolved and is divided into three-dimensional modeling data parsing and state parsing two parts, in three-dimensional model is resolved, to vehicle data, the bicycle data, pedestrian's data and signal lamp data are resolved, and resolution data is used to create objective, status data is resolved and is comprised wagon flow, the stream of people's position and speed data, resolution data is used for record and pays the value variable, creates displayed scene with paying after a value variable data reads real-time crossing data simultaneously according to objective then, finishes dynamic three-dimensional display.
The detection protocol that comprises three-dimensional modeling data and status data in the DETECTION OF TRAFFIC PARAMETERS software protocol bag, three-dimensional modeling data is meant vehicle data, bicycle data, pedestrian's data and signal lamp data, and status data is meant vehicle, bicycle and pedestrian's position and speed data.
Described road traffic controller is a TACT32 regional coordination control road traffic controller, and data communications equipment is switch or fiber optic, and Netcom of wireless office communication interface is the TCP/IP interface.
3-D image monitoring when platform is accepted the multichannel cause for gossip.
Good effect of the present invention:
1, on the urban road transportation control machine, installs the magnitude of traffic flow monitor supervision platform that communication interface is realized real-time online additional, effectively utilized the precious resources of existing urban road transportation control machine, improve science, the standardization of traffic administration, promoted the level and the process of urban modernization high-tech technical management.
2, only traffic is controlled and is detected, shows, to around building, view detect, show that traffic detects the specific aim of control to be strengthened greatly, picture is more clear, favourable with alleviate traffic control personnel's vision burden and psychological pressure.
3, when motor vehicles, non power driven vehicle and the stream of people are detected, also traffic signal control system itself is changed and detect, show, change etc. such as red greenish-yellow time cycle of signal lamp, improve the level of dynamic traffic management.
4, real-time three-dimensional dynamically shows, and is very directly perceived, lively, effective.
