Absolute differentiation relation in table structure or function, these are merely for convenience of description.
As shown in figure 1, trackside parking management method flow chart in an embodiment of the present invention.Trackside in present embodiment
Parking management method is a kind of parking management method based on REID, is directed to radio-frequency identification reader/writer and each
The interaction between the radio frequency recognizing electronic label that position and type are set is planted, to realize the management on parking stall, step is specifically included
S1, step S2, step S3, will launch to describe in detail respectively below.
Step S1, monitors the seizure condition on parking stall.Roadside Parking is managed and manages main difference with Parking
It is that the entrance and exit that Roadside Parking is not fixed to the parking vehicle on each parking stall, it is necessary to will carry out individually
Management.Therefore firstly the need of whether having the vehicle of parking, i.e. parking stall on detection parking stall either with or without occupied, followed by point
The information such as testing vehicle register and down time on analysis parking stall.The seizure condition for monitoring parking stall can be real in several ways
It is existing, for example, the magnetic field of the earth that surrounding is detected using earth magnetism ball changes to determine whether parking stall has vehicle.More implementing
In mode, can also be realized, it is necessary to illustrate by ultrasonic detection device, ground induction coil detection means, video detecting device etc.
It is that the seizure condition for monitoring parking stall is not limited with above-mentioned implementation method, in order to more accurately monitor the occupancy on parking stall
State, can also be applied in combination above-mentioned various sensing devices, the seizure condition on comprehensive analysis parking stall.
In the above-described embodiment, generally all there is the defect of itself in the sensing device on monitoring parking stall, be vulnerable to outer
The interference of boundary's environment causes to be unable to the seizure condition on monitor parking stall, it is most important that, if on each parking stall
Sensing device in above-mentioned implementation method is all installed, it is relatively costly.Therefore in a preferred embodiment, can be by parking
Set in position and take detection electronic tag, specifically, as shown in Fig. 2 taking detection electronic tag 11 is arranged on parking stall 10
Center, radio-frequency identification reader/writer 20 is arranged on the front portion on parking stall 10, and radio-frequency identification reader/writer 20 is by radiofrequency signal and occupancy
Detection electronic tag 11 is communicated, and reads the information that detection electronic tag 11 is returned that takes.But if vehicle 30 drives to stopping
When in parking stall 10, can just be sheltered from detection electronic tag 11 is taken, due to the characteristic of radio communication, now take detection
The return signal of electronic tag will be stopped by metal body, and can not normally be transferred to radio-frequency identification reader/writer 20, that is, penetrate
Frequency identification read write line 20 can not normally read the information for taking detection electronic tag 11.It should be noted that taking detection
Electronic tag 11 is the radio frequency recognizing electronic label similar with vehicle electron identifying, preferably by ultra-high-frequency passive radio frequency identification
Technology, below will be described.It is stored with occupancy detection electronic tag 11 and parking stall 10 is numbered correspondingly, radio frequency identification is read
Write device 20 by read illegal parking position 10 in take detection electronic tag 11 in store numbering can just find it is corresponding
Parking stall.As described above, the occupancy detection electricity in radio-frequency identification reader/writer 20 can not normally read specific parking stall 10
The number information of subtab 11, just illustrates there is occlusion on the corresponding parking stall 10 of the numbering, if can read, just says
Whether bright corresponding parking stall 10 is in idle condition, i.e., to read occupancy detection electronics mark according to radio-frequency identification reader/writer 20
Sign 11 whether idle to determine parking stall 10.
Step S2, when parking stall is changed into taking from the free time, the RSSI value returned according to vehicle electron identifying determines parking
The associated vehicle information of vehicle on position.Vehicle electron identifying is mounted in a kind of frequency identification electronic on vehicle front windshield
Label, the frequency range that it works in the range of 920MHz-925MHz, but can be not limited, and can use passive techniques, pass through
The carrier signal that radio-frequency identification reader/writer sends provides the energy of automotive electronics tag feedback signal.Stored in vehicle electron identifying
There is the information of vehicles of correlation, such as license plate number, vehicle brand, body color etc. read automobile electricity by radio-frequency identification reader/writer
Relevant information in sub-mark is it is known that the identity of correspondence vehicle.
Vehicle electron identifying can not only return to specific information when with radio-frequency identification reader/writer cooperating,
Corresponding RSSI can also be returned（Received Signal Strength Indication, the signal intensity of reception is indicated）
Value, the size of RSSI value is related to the distance of vehicle electron identifying to radio-frequency identification reader/writer, and RSSI value is bigger, shows vapour
Car electronic mark from radio-frequency identification reader/writer more close to, RSSI value is smaller, shows that vehicle electron identifying is got over from radio-frequency identification reader/writer
Far.Therefore, vehicle is parked on specific parking stall, and the RSSI value that the vehicle electron identifying on vehicle is returned should also be relative
In the presence of a numerical value for fixed range.During the information that vehicle is returned on specific parking stall is judged, it is only necessary to corresponding parking
Position sets corresponding benchmark RSSI value, and benchmark RSSI value is returned for substantially representing the vehicle electron identifying of parking stall peripheral location
The RSSI value numerical benchmark to be reached for returning, reads multiple vehicle electron identifyings and returns in radio-frequency identification reader/writer
Information of vehicles when, the degree of approximation of RSSI value and the benchmark RSSI value that can be returned according to each vehicle electron identifying comes true
Fixed which vehicle electron identifying is derived from specific parking stall.As described above, in order to choose specific automotive electronics mark
Know the information of vehicles for returning, benchmark RSSI value should be obtained first, since benchmark RSSI value is a metastable fixed value,
Therefore can be previously set, RSSI parameter lists can be for example set, rule of thumb and field engineering measuring and calculating be previously stored difference
The related benchmark RSSI value in parking stall, in after having vehicle to enter in certain specific parking stall, can inquire about this and specific stop
The corresponding benchmark RSSI value in parking stall and as analysis foundation.
But in practice, it may appear that the vehicle electron identifying installed on different vehicle front windshield belongs to different factories
Business, because different vendor has differences to the direction of vehicle electron identifying design optimization and content, therefore different vendor's production
Also can there is certain difference in the RSSI value returned between vehicle electron identifying, but be metastable in same manufacturer.
In addition, different vehicles, the angle of the vehicle glass that vehicle electron identifying is arranged on also difference also can be to automotive electronics mark
Know the RSSI value for returning and produce certain influence.So, following table it is exemplary be set forth in certain specific parking stall for not sympathizing with
Corresponding benchmark RSSI value under condition, same row represents same label manufacturer, same Setup Type is represented with a line.First, second, third point
Do not represent different label manufacturers, and A grades of car, B grades of car, SUV then example lists several Setup Types, A, B, C ... are then
Represent different label manufacturers and the corresponding benchmark RSSI value of Setup Type.Benchmark RSSI value described in table is as described above basis
The concrete numerical value that experience and field engineering measuring and calculating are previously stored, is used to what is expressed in table simply by alphabetical simple replacement
It is convenient.
Therefore, in the corresponding benchmark RSSI value in acquisition parking stall, automobile electricity can be read by radio-frequency identification reader/writer
Type of vehicle, tag types that sub-mark is returned etc., and inquire about right in RSSI parameter lists respectively according to different combined situations
The benchmark RSSI value answered, the benchmark RSSI value of acquisition is just as the analysis foundation of corresponding parking stall information of vehicles selection.
Preferably, as shown in Fig. 2 setting reference electronic label 12, reference electronic label 12 on the right side on parking stall 10
It is the radio frequency recognizing electronic label similar with vehicle electron identifying, with the radio-frequency identification reader/writer 20 for being arranged on the front portion of parking stall 10
Coordinate, be stored with the information bound with corresponding parking stall in reference electronic label 12, and such as parking stall is numbered accordingly.Benchmark electricity
Subtab 12 can be arranged in the other road serratd edge in Roadside Parking position, and can so ensure under normal circumstances will not be by vehicle etc.
Blocked.Due to reference electronic label 12 and the automotive electronics mark of installation on the front windshield of vehicle 30 being parked in parking stall 10
The position for knowing 31 is similar, therefore they are also suitable with a distance from radio-frequency identification reader/writer 20, so vehicle electron identifying is returned
RSSI value and reference electronic label 12 return RSSI value also should it is close seemingly.Obtaining the corresponding benchmark RSSI value in parking stall is
The RSSI value that the corresponding reference electronic label 12 in the side of parking stall 10 is returned is read by radio-frequency identification reader/writer 20.Need explanation
It is, as mentioned above due to the vehicle electron identifying manufacturer installed in the difference and vehicle of different vehicle front windshield angles
Difference, so the RSSI value that the reference electronic label 12 to getting is returned will also do further amendment, with guarantee and vehicle
The error of the RSSI value that vehicle electron identifying is returned reduces, for the modifying factor corrected can according to different Setup Types and
Label manufacturer has been previously set suitable numerical value, and the correlation values for inquiring about can be similar with above-mentioned RSSI parameter lists.
When the corresponding benchmark RSSI value in parking stall is got, it is possible to which automobile electricity judged by benchmark RSSI value
The information of vehicles that sub-mark is returned is corresponding with parked vehicle on parking stall.Specifically, choose and pass through radio frequency identification read-write
Information of vehicles of the RSSI value that the vehicle electron identifying that device reads is returned in benchmark RSSI value threshold range.As shown in Fig. 2 penetrating
There are multiple vehicles 30 in the identification range of frequency identification read write line 20, the vehicle electron identifying 31 on each vehicle 30 can be to radio frequency
Identification read write line 20 returns to corresponding information of vehicles, and it is Soviet Union that such as radio-frequency identification reader/writer 20 reads license plate number respectively
How A00001, Soviet Union A00002, Soviet Union A00003, Soviet Union A00004 related information of vehicles, judge which car is specific parking stall
On park cars, the RSSI value that can be returned by the vehicle electron identifying of above-mentioned return information of vehicles be judged, if car
It is parked on specific parking stall, the RSSI value that vehicle electron identifying is returned just should benchmark corresponding with specific parking stall
RSSI value is approximate, the RSSI value that the corresponding vehicle electron identifyings of A00003 of for example reviving are returned benchmark corresponding with No. 4 parking stalls
RSSI value is approximate, then just illustrate that parked vehicle license plate number is Soviet Union A00003 on No. 4 parking stalls.What vehicle electron identifying was returned
RSSI value all calculates approximate in the threshold range of benchmark RSSI value, and storing cycle is in parking stall in having allowed for practical application
There is certain deviation in front and back position, angle etc., and the RSSI value that vehicle electron identifying is returned can also exist with above-mentioned situation
Certain fluctuation, therefore the fluctuation of this respect can be offset according to actual conditions given threshold scope.
Step S3, bound with the corresponding parking stall according to the information of vehicles.When by radio frequency identification read-write
The information analysis that device reads draws the corresponding vehicle information of vehicle on parking stall, and information of vehicles is bound with parking stall,
So it is known that what identity is parked vehicle be on parking stall, the vehicle that can further record specific identity is assorted
When begin to use the information such as parking stall, corresponding parking management so also can be just launched to parking stall, such as calculate and stop
Expense, can be deducted fees when the vehicle of specific identity leaves corresponding parking stall by the corresponding account of vehicle.Vehicle stops
Can be according to the time decision that detection electronic tag is blocked be taken between at the beginning of car, the deadline of vehicle parking can be with root
Detect that the time that electronic tag is read by radio-frequency identification reader/writer again determines according to taking.
Preferably, automobile remote-control key signal receiving and processing device is provided near parking stall, it is specific when not receiving
The unlocking signal of identity vehicle, if now radio-frequency identification reader/writer is by reading the RSSI value that corresponding vehicle electron identifying is returned
Unusual fluctuations are there occurs, also or when read on corresponding parking stall occupy-place detection electronic labeling information, alert.
Further, camera head can be set near parking stall, and the RSSI value returned in vehicle correspondence vehicle electron identifying occurs
During unusual fluctuations, shooting is proceeded by with image information of human pilot in the travel direction and vehicle of registration of vehicle etc..
In more implementation methods, because the identification range of radio-frequency identification reader/writer is by the ripple of the radiofrequency signal received and dispatched
Valve is determined, in order to preferably cover parking stall, the lobe width of usual radiofrequency signal needs to be slightly wider than the region on parking stall, this
Sample is possible to the information of vehicles on the track of parking stall side can be read, and the RSSI that the vehicle on the track of parking stall side is returned
Value is also possible to approximate with corresponding benchmark RSSI value.In addition, in step s 2, being set when being compared with benchmark RSSI value
If threshold range it is unreasonable, for example threshold range setting is wide, will also choose neighbouring information of vehicles as right
The information of vehicles that parking stall is to be bound is answered, the associated vehicle information so chosen by benchmark RSSI value will have multiple, and
In fact because correspondence parking stall can only park a car, therefore there may be only the corresponding vehicle of information of vehicles and be only park
On correspondence parking stall.
As shown in Fig. 2 position detection electronic tag 131,132 is set into the side that the vehicle of parking stall 10 enters, in trackside
In parking, the side that the vehicle of parking stall 10 enters is primarily referred to as the left side on parking stall 10, and the judgement in "left", "right" direction is to sit
It is defined with the direction corresponding to right-hand man on road direct of travel identical vehicle.Enter position detection electronic tag 131,132
It is a kind of radio frequency recognizing electronic label coordinated with radio-frequency identification reader/writer 20, it is also possible to correspondingly using passive ultra-high frequency radio frequency
Whether identification technology, role can be similar with detection electronic tag 11 is taken, read by radio-frequency identification reader/writer 20
Passed through with determining whether vehicle to corresponding label information.
When vehicle 30 enters parking stall 10, common mode is entered in the way of reverse gear from the front end in the left side of parking stall 10
Parking stall 10, or previous trailing from the left side of parking stall 10 enters the mode of shelves and enters parking stall 10.Therefore, position detection electronics is entered
Label 131,132 specifically include first enter position detection electronic tag 131 and second enter position detection electronic tag 132, first enters position
Detection electronic tag 131 is arranged on the front end in the left side of parking stall 10, for detecting that vehicle reverse gear enters the mode on parking stall, second
Enter the rear end that position detection electronic tag 132 is arranged on the left side of parking stall 10, for detecting that vehicle drive shift enters the side on parking stall
Formula.But, in a special case, because front and rear parking stall 10 is all in idle condition, vehicle has into the mode on parking stall
Be probably from before parking stall parking stall enter, then poured into always from the front side on parking stall, or from parking stall
Rear side enters, therefore can also be respectively provided with the front side on parking stall and rear side according to demand into position detection electronic tag, point
The mode that vehicle enters from neighbouring parking stall Yong Yu not detected.But in order to preferably manage the parking period of vehicle, Ke Yi
The rear end in each region of parking stall 10 is provided with catch on wheel, can so prevent vehicle from entering from adjacent parking stall, reduces
Enter the complexity of position detection, when on the other hand can also ensure adjacent stalls all in the free time, because storing cycle is not in place
A car is caused to take the situation on multiple parking stalls.
Specifically, as shown in figure 3, when vehicle 30 enters parking stall 10 with reverse gear, vehicle 30 first passes around first and enters position
Detection electronic tag 131, when vehicle enters position detection electronic tag 131 without first, radio-frequency identification reader/writer can be normal
Read first enter position detect electronic tag 131 information, but when vehicle 30 passes through, due to first enter position detection electronics
Label 131 is by occlusion, so radio-frequency identification reader/writer can not read first enters position detection electronic tag 131, now
It was recorded as the second time.During vehicle 30 continues into parking stall 10, occupy-place detection electronic tag 11 is blocked, this
When can be recorded as the very first time, for marking parking stall occupied time point.It should be noted that the second time be in order to
Find vehicle 30 and have just enter into time point on parking stall 10, by be first to enter the change that the return information of electronic tag 131 is detected in position
Change, and first enters position detection electronic tag 131 situation about being blocked it could also be possible that what the vehicle for passing by was caused, so should be with
It is recent based on the very first time because the last time situation about being blocked necessarily vehicle 30 is caused into parking stall 10
's.Stop complete after first enter position detection electronic tag 131 avoid blocking for vehicle 30, radio-frequency identification reader/writer is again
Read first and enter position detection electronic tag 131.As described above, in the second time between the very first time, being vehicle 30 falling
Shelves enter the process on parking stall 10, therefore the RSSI value of the return of vehicle electron identifying 31 on vehicle 30 should be known with from radio frequency
The increase of the distance of other read write line and be gradually reduced, this with the side track of parking stall 10 on RSSI value for returning of the vehicle that advances change
It is completely different.So can be judged in second time to described between the very first time according to a mode that enters for vehicle
Whether the RSSI value change that the corresponding vehicle electron identifying of information of vehicles is returned matches.For example, when radio-frequency identification reader/writer reads
RSSI value to the return of multiple automotive electronics labels, can be by judging their change in the threshold range of benchmark RSSI value
Situation come judge the corresponding vehicle of which vehicle electron identifying be parking vehicle, if variation pattern mismatch, just explanation
It is the information of other vehicles return outside parking stall, parking stall not corresponding with this is bound, if matching is put into step
S3。
Similarly, as shown in figure 4, when vehicle 30 enters parking stall 10 with drive shift, vehicle 30 first passes around second and enters position
Detection electronic tag 132, when vehicle enters position detection electronic tag 132 without second, radio-frequency identification reader/writer can be normal
Read second enter position detect electronic tag 132 information, but when vehicle 30 passes through, due to second enter position detection electronics
Label 132 is by occlusion, so radio-frequency identification reader/writer can not read second enters position detection electronic tag 132, now
It was recorded as the second time.During vehicle 30 continues into parking stall 10, occupy-place detection electronic tag 11 is blocked, this
When can be recorded as the very first time, for marking parking stall occupied time point.It should be noted that the second time be in order to
Find vehicle 30 and have just enter into time point on parking stall 10, by be second to enter the change that the return information of electronic tag 132 is detected in position
Change, and second enters position detection electronic tag 132 situation about being blocked it could also be possible that what the vehicle for passing by was caused, so should be with
It is recent based on the very first time because the last time situation about being blocked necessarily vehicle 30 is caused into parking stall 10
's.Stop complete after second enter position detection electronic tag 132 avoid blocking for vehicle 30, radio-frequency identification reader/writer is again
Read second and enter position detection electronic tag 132.As described above, in the second time to before between the very first time, being vehicle 30
Enter shelves into the process on parking stall 10, therefore the RSSI value of the return of vehicle electron identifying 31 on vehicle 30 should be with from radio frequency
Recognize the reduction of the distance of read write line and gradually increase, this with parking stall 10 by the RSSI value that returns of for example static vehicle change
It is completely different.So can be judged in second time to described between the very first time according to a mode that enters for vehicle
Whether the RSSI value change that the corresponding vehicle electron identifying of information of vehicles is returned matches.For example, when radio-frequency identification reader/writer reads
RSSI value to the return of multiple automotive electronics labels, can be by judging their change in the threshold range of benchmark RSSI value
Situation come judge the corresponding vehicle of which vehicle electron identifying be parking vehicle, if variation pattern mismatch, just explanation
It is the information of other vehicles return outside parking stall, parking stall not corresponding with this is bound, if matching is put into step
S3。
