Abstract

The invention relates to an intelligntize traffic control which is the application of wire radio-frequency technique. It lays the electric tag and wireless radio-frequency receiving antenna on the road and posited them under the carriage chassis. It uses computer controlling technique and computer network technique to achieve road crossing's intelligntize control, carriage rules and regulations violation checking, carriage's ECT electric auto charging, carriage's message voice navigation and carriage position tracing.

Description

The application of wireless radio-frequency on intelligent traffic administration system

Technical field: radio-frequency technique worldwide, at full speed grows up, we new one the band I.D. be exactly illustration.In the ITS field more is to utilize it to realize ETC (electronic charging).And if the present invention utilizes wireless radio-frequency to be applied in the intelligent traffic administration system aspect.

Background technology: the RF electronic label technology is used and the at present positive research and inquirement stage of traffic administration, chases after its reason: one, be that any experiment and application all will be employed the huge social resource.Two, the fast development of RF technology makes the RF The Application of Technology not launch on a large scale.At present, the RF technology reaches its maturity.Its a lot of indexs can satisfy the needs of every profession and trade with warp.At field of traffic, the RF technology has tentatively possessed the condition of broad scale research development and application.

Summary of the invention: the present invention is applied to intelligent transportation manage with wireless radio-frequency.Electronic tag and less radio-frequency transmit receive antenna applied establishing on the road and be installed under the motor-vehicle chassis.Utilize Computer Control Technology and computer networking technology to realize the intelligent management of road cross; Motor vehicles are violating the regulations to be detected; The ETC automatic electronic charging of motor vehicles; Follow the tracks of the short message voice navigation and the motor vehicles location of motor vehicles.

Embodiment:

1. this system is based on existing means of transportation resource, make full use of the community network resource, vehicle flowrate, each crossing at each crossing are treated that information such as lamp motor vehicle quantity, vehicle peccancy are sent to command centre's cluster server, be presented on the giant-screen of point duty Surveillance center after handling by cluster server.

2. the crossing data processor mainly is the data of individual data harvester collection are judged with the information of point duty etc. and to be handled.Transfer the state of traffic lights automatically.Vehicles peccancy, crossing flow, crossing are treated information such as car quantity are sent to cluster server.

3. data gather computer central authorities are with information of vehicles, comprise that information such as quantity accumulative total, car speed send into the crossing data processor.Signal source adopts radio-frequency technique.With the Information Monitoring of a section with a plurality of parallel connections signal radiated element/receiving element.

4. data gather computer central authorities are with information of vehicles, comprise that information such as quantity accumulative total, car speed send into the crossing data processor.Signal source adopts radio-frequency technique.With the Information Monitoring of a section with a plurality of parallel connections signal radiated element/receiving element.

1. signal collecting element: can be made into various ways according to present RF technology development situation signal emission/receiving belt, as: paste, bury, inlay etc.The very book that it can be done, holding with tag line is one.This signal emission/receiving belt is two card mixed structures.The information of one side receiver motor-car electronic tag.Also send azimuth information simultaneously to motor vehicle.

5. radio-frequency card is installed on the chassis of motor vehicle.The big I of its shape has multiple choices.As selected two cards, and cooperating with electronic tag on the road surface and short message voice navigating instrument, real-time report is to the traffic conditions and the track route suggestion of destination.

6. news network: utilize social existing Internet resources, signal transmission resources such as reasonable disposition optical cable, telephone wire, twisted-pair feeder and power carrier.

7. a upright complete cover information processing and a control construction adopts information acquisition to distribute, control local cluster.The information processing platform that overall data is synchronous.

8. develop vehicle-mounted short message voice equipment.Set up the quick service system that integrates with traffic control center vehicle guidance server

9. owing to each motor vehicle electronic tag has been installed all, driving vehicle highway section that records vehicle that total system can be real-time and the time that enters this highway section.It is connected with banking system, just can realizes the automatic note expense and the charge of electronics.
