Description
Technical field
The present invention relates to the intelligent management of urban transportation, comprise the RF identification and the location technology of vehicle.
Background technology
The quick increase of city vehicle quantity has brought huge pressure for all city traffic management, particularly country that is in the fast development as China.Because the construction of road-based infrastructure not only needs the input of substantial contribution, yet can bring many other problems simultaneously.Thereby the utilization factor of raising urban transportation infrastructure realizes that the intellectuality of urban traffic control is first-selected beyond doubt, and this also is the challenge that all modern big cities faced.The key issue that the urban transportation intelligent management at first faces is exactly as a kind of cost-effective mode how to realize the real-time collection and the transmission of urban traffic information, and realize the real-time navigation to vehicle on this basis.
The way that the most often adopts at present has:
Through the artificial information of gathering vehicle flowrate of the mode that video monitoring is installed.The advantage of this way is directly perceived, but that its shortcoming is not only the installation and maintenance cost is high, and is difficult to realize exactly that digitizing manages automatically.
Through various sensors, for example ground induction coil calculates through vehicle number purpose way.This method is not only with the trouble of next various construction managements, and device damage is also very serious;
Through active electronic label car plate (E-Plate), rice is gathered the method for information of vehicle flowrate.Because being a kind of single uninterrupted periodicity, the E-Plate electronic tag repeats outwards to launch the active electronic label of self identity information; Thereby; When vehicles a large amount of in the city is all simultaneously outwards launched wireless signal repeatedly, must cause the electromagnetic pollution of environment, disturb the work of other communication system; Also cause simultaneously self signal to block up and make reader can't collect the id information of all roads, thereby also just can't realize the real-time collection of information of vehicle flowrate through vehicle;
Come vehicle is carried out the real-time positioning monitoring through GPS and mobile communication terminal (GPRS) are installed onboard, thereby obtain the method for information of vehicle flowrate.Obviously, this method is equipment installation and maintenance cost high (GPS+GPRS+ power supply) not only, and has the problem of paying Internet utilization fee for a long time to mobile communication carrier; In addition, also exist and permitted local GPS in the city and can't work, and gprs system need guarantee in time many other problems that a large amount of vehicle position informations are transferred to control center in real time and are brought.
Through only going up GPS and mobile communication terminal are installed, are come to obtain indirectly the method (FCD) of road traffic condition at part car (for example taxi).The existing problem of vehicle-mounted (GPS+GPRS+ power supply) method except using itself; Though this method part has been alleviated the contradiction that GPS and mobile communication terminal need the substantial contribution input is installed on all vehicles; But it can only partly reflect urban traffic amount situation, thereby has reduced the accuracy of the information of vehicle flowrate of inferring in view of the above.This is not only because the actual state that the vehicle fleet size of GPS and mobile communication terminal can't truly reflect road very little is installed; And on the such special car of taxi, install; Also can tend to avoid the highway section that blocks up because of the taximan through themselves intercom system, thus the validity of the information of reduction.
And existing airmanship has:
The GPS navigation technology; A GPS navigation appearance promptly is installed on each car; Human pilot carries out initialization to GPS earlier before setting out, and imports the destination then, and the GPS navigation appearance will be through the electronic chart that self stores; Circuit is selected in requirement according to the user, and constantly corrects according to the new location information that occurs in the driving procedure in the process of moving.This navigate mode, except the problem that aforesaid employing gps system can not be evaded, it does not consider the real-time congestion of road traffic fully, thereby the effect in the city of ubiquity traffic congestion now of this navigate mode is very limited.
Based on the navigate mode of FCD information, this mode is a kind of improvement to the GPS navigation mode of pure dependence electronic chart.This mode is the congestion information with urban road, sends to the vehicle that has the GPS navigation device with the mode of broadcasting, and the GPS navigation device according to these information, is revised navigation way more then; Perhaps through SMS or other mode drivers.Yet this method can't accurately be gathered the information of vehicle flowrate on each crossing different directions, thereby, also can't foundation reliably be provided to the high-efficiency management of each crossing traffic lights of city.Thereby it is limited to the managerial role of entire city traffic intelligent.And this system can only be to having installed GPS navigation equipment, and be not in the vehicle performance certain function of gps signal blind area, and GPS navigation equipment is not installed and is in the vehicle of gps signal blind area useless to the overwhelming majority.
In sum, the acquisition mode and the automobile navigation mode of information measured in the urban traffic of using now, all can not satisfy the needs of urban transportation intelligent management well.
Summary of the invention
Technical matters to be solved by this invention; Be exactly in the existing urban transportation intelligent management; Information of vehicle flowrate is gathered in real time and the existing defective of navigation management, has invented a kind ofly not rely on the GPS terminal but utilize i-RFID (Interactive RFID interactive intelligent electronic tag) technology, realizes urban traffic amount real time information sampling at low cost; And according to real-time traffic flow amount information material on each crossing different directions that is collected; Automatically navigate traffic lights switching time on the adjustment different directions, and the vehicle in being gone in the city in a different manner, with the method for the service efficiency of improving the entire city road.This method is less equipment investment not only, and the installation and maintenance cost is low, but also can bring the many benefits in other many city vehicles and the traffic administration.For example do not need extra input, just can realize the block up automatic collection of expense of city, the automatic fee charging management that do not stop, the automatic identification of clone's vehicle, and will effectively hit the expense of evading and criminal offense vehicle etc., thus improve the level of urban traffic control greatly.
System architecture
The present invention relates to vehicle-mounted i-RFID label (being called for short label later on); Be installed in the telegon and the reader of traffic intersection; And the traffic control and management computing machine that is connected with reader through wired or wireless mode and telegon; Comprise the navigator that navigation software and electronic chart are installed that is connected with label in case of necessity, or the navigator that navigation software and electronic chart and mobile communication terminal module are installed that is connected with label.(referring to accompanying drawing)

Description of drawings is used for i-RFID system architecture and the working method figure that information of vehicle flowrate is gathered
Embodiment
(1) label: the fixed position on each car; The i-RFID intelligent electronic label (being called for short label later on) of an anti-dismounting for example is installed on the car front windshield angle, and they have unique in the world ID numbering (also can be renumberd by user oneself as required certainly).Label can write down and store a certain amount of information, and the driver can also write the information (for example using the multi-functional mobile phone that is connected with label) of vehicle ' destination through different modes to label in case of necessity.
This label is not outwards launched any signal usually, but every time at a distance from about 1s, and periodically monitoring reception wakes command signal from telegon up with what broadcast mode was sent on the monitoring channel of special use.
Label should have the function of anti-dismounting.Use No. 5 lithium battery to drive, can use generally speaking and need not change battery in 5 years.
(2) telegon and reader: each need carry out the crossing, road of vehicle and traffic monitoring in the city; A telegon and a label reader that is operated on the different channel are installed; They are connected with the computing machine of traffic control system through wired or wireless network (optical fiber, ADSL or GPRS etc.).This computing machine can be the control computer of management entire city traffic, also can only manage the simple computers or the single-chip microcomputer of these crossing traffic lights.They can use the power supply of 220V civil power or other power supply, power consumption generally all＜1W.
(3) in-vehicle navigation apparatus:
General in-vehicle navigation apparatus is meant and stores the urban transportation electronic chart, corresponding management software and the electronic equipment that best travel route can be provided to the driver through voice or screen display.They all rely on the GPS terminal and satellite obtains vehicle position information.They can be the ordinary GPS navigating instruments, have the multi-functional mobile phone of GPS function.And the navigator here is not rely on GPS but obtain vehicle position information through vehicle-mounted label and the i-RFID telegon and the reader that are installed in the fixed position.The in-vehicle navigation apparatus here; An i-RFID label all is installed; And receive information from each crossing telegon to confirm the position of self through label; Navigation software comprises urban traffic situation and congestion information in case of necessity, so that can be revised to the travel route of oneself according to real-time road condition information and electronic chart in real time.For the navigator that mobile communication terminal is installed, can also be through moving the real-time information that public network obtains the urban traffic amount.In-vehicle navigation apparatus should have the function of input vehicle ' destination information, and the destination information that goes of this input also must finally be passed to the traffic control system computing machine through label or mobile public network terminal module.
(4) label, running parameter between telegon and the reader requires: each telegon or reader must guarantee to have the ability of the vehicle-mounted label of the maximum vehicle flowrate that processing possibly occur.For example, should not be lower than 20/second=72000/hour, otherwise need to use the mode of frequency division, the quantity that increases reader improves the ability of i-RFID system handles label.The position of telegon and reader preferably is installed in higher position, crossing; For example on the Traffic signal post or on the illumination lamp stand; To guarantee under the various situation that possibly occur (for example vehicle block etc.), can both in the distance range that requires, realize with all directions on the two-way communication of vehicle-mounted label.
The two-way communication distance of label and crossing telegon and reader can be adjusted according to the magnitude range and the actual conditions at crossing.Generally should be when passing through this signal cover according to the vehicle that goes with prestissimo (can be thought of as 100 kilometers/hour); Should guarantee to have at least the time in 5 seconds to be in the signal cover of telegon and read write line, and the signal cover non-overlapping of adjacent intersection reader is a principle.
The independent channel that each crossing can supply reader to use can have a plurality of, and different crossings reader can be selected different communication channels for use according to the concrete wireless communications environment in this crossing, with avoid and the existing wireless communications system between the interference that possibly cause.And the telegon through this crossing instructs the channel that this crossing of notified tag should be used to the label broadcast message.But it is consistent that the employed channel of the telegon at all crossings and the employed monitoring channel of all labels must be unified, and can employable channel all inequality with all readers.If possible, this channel channel of a special use preferably.The employed frequency range of whole i-RFID system should be stipulated consistent with concerned countries; Here international 2.4G frequency range is used in suggestion; And employed channel bandwidth generally should can be easy to avoid and the mutual interference mutually that has now between other 2.4G wireless system less than 3Mhz like this.For reliability that guarantees system works and the antijamming capability that improves system, the i-RFID system should adopt the direct sequence spectrum spread communication technology.
(5) at the less crossing of vehicle flowrate, in order to save cost, telegon and reader can be born by same equipment through the mode of time-division.For example use waking up on the channel of the present telegon work of reader, continuous uninterrupted is sent the command signal of waking up of a period of time to label, and then jumps on the working channel of reader and wait for the information that receives from label.The cycle of monitoring signal after the time T of uninterrupted continuously emission wake-up signal should be revived greater than the label sleep; And each label receive wake command signal up after with automatic time delay T after; Jump to again on the working channel of reader and transmit, establish a communications link with reader.
Practical implementation
Telegon through broadcast mode uninterruptedly continuously, or intermittence all vehicle-mounted labels in getting into crossing telegon signal cover continuously send and wake command signal up.The time of general each continuous emission should surpass the label sleep and revive the cycle of monitoring signal afterwards.And the time in each gap is depended on the size of each crossing traffic flow.The content of command signal should comprise the Position Number that writes this crossing to label, and label should use that the reader at which channel and this crossing communicates etc., also can comprise real-time road condition information in case of necessity.This signal instruction requires label behind the Position Number at the crossing of noting this telegon place, jumps to immediately on the new assigned work channel, and anticollision mode as requested (is consulted " based on the collision-proof method of interactive electronic label technique ".Number of patent application: 201010194562.6) reader to this crossing transmits, and up to receiving the receipt that has received this signal from reader like clockwork, or surpasses till the time restriction of predesignating (about 20 seconds).This signal comprises label ID (number corresponding with this vehicle license plate); This vehicle the Position Number at a last crossing of process; Comprise that in case of necessity (vehicle ' destination locations numbering can write label in several ways by the vehicle driver for the numbering of vehicle ' destination locations; For example use the multi-functional mobile phone that can communicate with label, or have the label etc. of input media).Latter two information is used to judge the travel direction of crossing vehicle.
Label will stop emission immediately after receiving the affirmation receipt signal that read write line beams back, and will get back to and monitor on the channel in dormancy certain hour (for example back about 20 seconds) back redirect, continue to monitor the signal instruction of sending with broadcast mode from telegon.
What of the number of times of same label signal same crossing reader receive from, can reflect the jam situation at this crossing, again according to the target travel direction of different vehicle, just can know size and the smooth traffic situation of knowing vehicle flowrate on the different directions.
