Embodiment
The RFID technology is general, and people can be used for various uses to it, the RFID technology is used as traffic information collection here.The information of relevant vehicle comprise relation under the vehicle RFID identification code, license plate number, vehicle, car owner's ID (identity number) card No., vehicle management district genus, information of vehicles all accurate recording on the RFID electronic tag, the electronic tag of this specific customization is attached on the objects such as vehicle, car plate, comprehensive traffic card, I.D., as motor vehicle, bicycle, people, when passing through rfid interrogator (traffic information collection device) in the carrier with RFID electronic tag, rfid interrogator will collect information accurately.Certainly, we also can pass through microcomputer data processing, and the identification code of unique identification identity of the vehicle that RFID is obtained is associated with essential informations such as the register information of vehicle, ID (identity number) card No., realize that comprehensive traffic information uses.
Different traffic behavior persons are for the RFID traffic signal control system, and its principle is identical, are example with car as the traffic behavior person below, illustrate that concrete scheme is as follows.
As shown in Figure 1, treated RFID electronic tag 1 is installed in the position that does not influence pilot's line of vision on the vehicle windscreen, is installed in usually on the windshield of automobile rearview mirror back.As shown in Figure 2, eyes front in the car, the position that electronic tag 1 can be installed on the windshield.The read write line 2 of RFID is arranged on the road, the read write line of RFID and road traffic signal controller 4 communicate, road traffic signal controller 4 links to each other with stop-gi sugbal display system 3, and road traffic signal controller communicates by network and traffic information collection processing enter.As shown in Figure 3, the rfid interrogator 2 that is installed in track top constantly sends radiofrequency signals, and when the vehicle that is loaded with the RFID label entered rfid interrogator and effectively reads and writes scope, the RFID electronic tag that is contained on the vehicle received the radiofrequency signal that read write line sends.As shown in Figure 4, the RFID electronic tag is according to the signal of read write line, send data to the read write line of top, track, read write line receives the answer signal of electronic tag, and calculate effective information, deliver to traffic signal controlling machine or directly deliver to background processor and further handle by data communication channel.Thereby finish default systemic-function and identification automatically, thereby realize the automatic management of traffic.
In fact, system of the present invention is not only can the cognitron motor-car, so long as have in advance any object of electronic tag that can allow rfid interrogator identification of customization, appear at such as the people who has electronic tag, bicycle, vehicle using motor, pet within the effective range of this read write line, can discern processing automatically.The mounting means of rfid interrogator can according to detected object with detect the different of place and change, such as being installed in the roadside by vertical rod, can the machines motor vehicle, bicycle etc.
Use for traffic information collection,, rfid interrogator can be arranged on intersection, relevant road segments according to the purposes difference of Information Monitoring.A plurality of intersections or highway section are provided with the traffic information collection that this rfid interrogator forms a face, comprehensively can draw a lot of useful transport information in this zone through handling.Thereby can realize magnitude of traffic flow collection, traffic signals control, vehicle identification, vehicle tracking etc. effectively.
Being arranged near the rfid interrogator of road junction is connected with road traffic signal controller by the serial data communication link, be used for replacing being embedded in the ground sense vehicle magnetic test coil on the track, real-time control foundation as road traffic signal controller 4 has lot of superiority.Road traffic signal controller can be uploaded to background processing system to the transport information that obtains and realize traffic information collection simultaneously.
Be arranged near the road junction rfid interrogator and can directly utilize wired or wireless communication system sends the transport information of gathering to background processing system, thereby realize the purpose of traffic information collection and utilization.
Except the rfid system that is provided with in order to gather transport information specially, a large amount of rfid systems that is used for other purposes, as the radio frequency automatic identification no-stop charging system, the radio frequency automatic identification managing system of car parking that do not stop, the radio frequency automatic identification commerial vehicle management system of not stopping, the radio frequency automatic identification special vehicle management system of not stopping, the radio frequency automatic identification emphasis vehicle monitoring tracker or the like of not stopping, the information relevant of all radio frequency automatic identification system acquisition with traffic, can carry out information sharing, gather and processing and utilizing as source of traffic information.
The installation site of electronic tag card: the sticker after the numbering to the vehicle of correspondence or be installed on the deck.
(by the driver on one side on) the isolated island, so electronic tag installation position seat should be attached to the position on the limit of taking back on the windshield, as shown in Figure 1 because parking lot equipment generally is installed in the left side, track.Paste with reference to the A among Fig. 2, B, C size for compact car (containing common minibus) electronic tag support.Pasting if truck or motor bus should suitably down paste electronic tag with reference to the D among Fig. 2, E, F position dimension, is principle with the sight line of not blocking the driver.If antenna is installed in the driver on one side, label also should be attached to A, the E position of windshield so.If antenna be contained in the track directly over, then label should be too in car near back car mirror or windshield center line B, the F position.If antenna is installed in the copilot limit, label also should be attached to C, the D position of windshield so.
Traffic signal control system based on RFID: the foundation of traffic signals control is a road actual motion state, the actual motion state of road is to rely on road data to obtain and analyze to draw, and how obtaining the road service data is one of gordian technique of traffic signals control.For many years, traffic monitoring is by inductive coil detecting device, ultrasonic sensor, radar sensor and infrared sensor etc., the present invention is used for road data with the RFID technology and obtains, utilize rfid interrogator to obtain the road condition information such as the motor vehicle that is loaded with the RFID electronic tag, bicycle or pedestrian of process search coverage, and be transferred to this regional road traffic signal controller, realize the purpose of road traffic signal control.Simultaneously, the transport information that rfid interrogator is obtained by traffic signal controlling machine sends bit processing machine to and is further analyzed processing.
Because the RFID label itself has considerable information capacity, be enough to allow the deviser deposit similar substrates type, container name, the affiliated relation of carrier, carrier registration address and unit, signal of carrier sign indicating number or the like information.RFID equipment can arrange that in crossing, the highway section of needs after RFID read and write these data, system can handle, analyze these data, thereby drew the active path and the mechanics of carrier according to the general plan scheme.These data can be directly used in control of traffic and road, control, can draw complete traffic information data together in conjunction with other traffic information collection technology according to the configuration degree of carrier label, can be used as traffic OD matrix norm type data.
