Abstract
The invention provides a real-time acquisition device for an automobile flow of an urban expressway. The device is fixed on a lamppost at a ramp crossing of the urban expressway, wherein a card reader in the acquisition device is used for reading card-type compulsory traffic insurance signs pasted on front windshields of automobiles entering or running out of the ramp crossing of the urban expressway, so that acquisition of the automobile flow is realized; and acquired information of the automobile flow is sent to a control circuit of a traffic management center regularly by using a radio communication circuit in the device.
Description
Technical field
The present invention relates to the transport information field, particularly based on the flow motor real-time acquisition device of cassette compulsory insurance for traffic accident of motor-drivenvehicle sign.
Background technology
The present automobile pollution of China is through hundred million, and along with the raising of living standards of the people, this numeral will inevitably continue to increase.The sharp increase of automobile quantity has brought some negative effects to people's life, and wherein traffic jam is that traffic administration personnel and driver are reluctant experience.In order to alleviate the urban traffic pressure, the major measure that China takes big and medium-sized cities at present is to build city expressway (being commonly called as overpass).Because the city expressway pavement quality is high and do not establish traffic signals, the travel speed of automobile is very fast under normal circumstances, can alleviate to a certain extent the traffic pressure of road network.But owing to maintaining sustained and rapid growth of city automobile quantity, the state that vehicle flowrate is saturated or block up also can appear in the main through street of some of city in special time.At present the technology of vehicle Flow Detection mainly contained three kinds: the first is installed ground induction coil under the roadbed of road, adds that the testing circuit of complexity is realized.This method has shown numerous drawbacks in implementation process, no longer have use value at present.Second method is the camera Real-time Collection pavement image that utilizes the urban road crossing to arrange, and then carries out image recognition, and judging has several cars to pass through.This method realizes that the cost of vehicle flowrate is higher, and software realizes that the difficulty that automatically detects is larger.The third method is to utilize Vehicular satellite positioning system (address commonly used is GPS), utilizes radio communication to add up the vehicle flowrate in a certain highway section.Because the prerequisite of this method statistic vehicle flowrate is that the automobile that travels on the way all is furnished with GPS, also is difficult to reach with regard to the national conditions of present China.
Summary of the invention
The problem that exists for solving the motor current flow real-time statistics, make things convenient for simultaneously traffic control department in time to find and process vehicles peccancy, guarantee the public safety of city road network, the invention provides a kind of city expressway flow motor real-time monitoring system based on cassette compulsory insurance for traffic accident of motor-drivenvehicle sign.
The objective of the invention is to be achieved through the following technical solutions:
A kind of city expressway flow motor real-time acquisition device, the automobile of registering in the city all uses under the prerequisite of cassette compulsory insurance for traffic accident of motor-drivenvehicle sign, adopts REID to realize the Real-Time Monitoring of city expressway flow motor, and its concrete steps that realize purpose are as follows:
1, cassette compulsory insurance for traffic accident of motor-drivenvehicle sign adopts the passive radio frequency identification circuit, need not to arrange power supply in the sign;
2, the automotive vehicle owner sticks on cassette compulsory insurance for traffic accident of motor-drivenvehicle sign the upper right corner of windshield glass of automobile in accordance with regulations;
3, after the automotive vehicle owner has bought the compulsory insurance for traffic accident of motor-drivenvehicle in certain year, the staff utilizes hand-held read-write that the relevant information of compulsory insurance for traffic accident of motor-drivenvehicle is write cassette compulsory insurance for traffic accident of motor-drivenvehicle sign;
4, the ring road entrance and exit in city expressway arranges radio-frequency card reader, and the identification range of card reader is controlled in the one direction track;
5, by reading the information in the cassette compulsory insurance for traffic accident of motor-drivenvehicle sign that enters ring road or exit ramp automobile, information of vehicle flowrate is carried out statistic of classification;
6, the card reader circuit of fast road ramp mouth sends to the traffic control central control circuit by the form of radio communication with flow motor information;
7, the traffic control center utilizes control software that the automobile quantity that all ring road entrances of same direction sail into is cumulative in real time, deducts the automobile quantity that all ramp exits roll away from again, can obtain certain section city expressway one party to vehicle flowrate.
8, the traffic control center can be distributed to the driver by the form of broadcasting station or gps signal, and the driver can avoid the highway section that blocks up according to real-time traffic information.
Characteristics of the present invention are: because the with low cost and serviceable life of passive radio frequency identification circuit is very long, so the indispensable cassette compulsory insurance for traffic accident of motor-drivenvehicle sign of each automobile has exploitativeness.Radio-frequency card reader is set at city expressway ring road crossing can adopts the street lamp mains supply and be fixedly mounted on the lamp stand of ring road mouth, easy construction and need not destroy the road surface, cost is also very low.In sum, the employing REID is low at city expressway ring road crossing monitoring flow motor cost, speed is fast, precision is high.
Description of drawings
The present invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is cassette compulsory insurance for traffic accident of motor-drivenvehicle sign structure figure of the present invention.
Fig. 2 is flow motor harvester control circuit structural drawing of the present invention.
1. cassette compulsory insurance for traffic accident of motor-drivenvehicle sign shell, 2. compulsory insurance for traffic accident of motor-drivenvehicle sign, 3. radio circuits among Fig. 1.
Embodiment
1, the automotive vehicle owner is with the upper right corner position of cassette compulsory insurance for traffic accident of motor-drivenvehicle symbol sticking in automobile wind shield glass;
2, the automotive vehicle owner buys compulsory insurance for traffic accident of motor-drivenvehicle to compulsory insurance for traffic accident of motor-drivenvehicle payment on behalf company;
3, compulsory insurance for traffic accident of motor-drivenvehicle is payed on behalf company according to the compulsory insurance for traffic accident of motor-drivenvehicle situation that the car owner buys, and utilizes read-write equipment that this compulsory insurance for traffic accident of motor-drivenvehicle information is write in the radio circuit (3) of cassette compulsory insurance for traffic accident of motor-drivenvehicle sign shown in Figure 1, and utilizes display device that this information is shown to the car owner and check;
4, automobile is when entering or rolling away from city expressway ring road mouth, in case when running into the flow motor harvester that arranges on the light pole, the information in its cassette compulsory insurance for traffic accident of motor-drivenvehicle sign namely is read and is counted;
5, the flow motor harvester is according to the demand at traffic control center, can pass through radio communication circuit (such as using GSM network etc.) per 30 seconds and send a flow motor information to the traffic control center, the flow motor in each highway section can be grasped according to the information that all flow motor harvesters that are arranged on city expressway ring road mouth are sent in the traffic control center, and being distributed to the driver by the form of broadcasting station or gps signal, the driver can avoid the highway section that blocks up according to real-time traffic information.
