Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present application, the technical scheme in the embodiment of the present application is carried out clear, complete
Site preparation describes it is clear that described embodiment is only some embodiments of the present application, rather than whole embodiments.It is based on
Embodiment in the application, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of the application protection.
Before the parking lot management method based on UWB technology of the application offer is provided, introduces one kind first and be based on UWB
Technology parking system, including at least one parking lot management server, is connected with parking lot management server, interval is laid in
A plurality of UWB base stations of parking area；Also include at least one UWB label and at least one UWB board units, UWB label and
UWB board units in a plurality of UWB base station ranges in real time or the cycle transmission framing signal to a plurality of UWB base stations,
Wherein UWB label is got by the target vehicle being fitted without UWB board units when entering parking lot, and UWB board units are
User's vehicle is before entering parking lot already installed on vehicle.
Method includes：
S101:Receive UWB label in the coverage of described a plurality of UWB base stations in real time or the cycle send first fixed
Position signal, wherein said UWB label is that target vehicle is issued to described target vehicle when entering described parking lot；
It should be understood that UWB label can be the communication module having passed through UWB label before being issued to target vehicle
Enter line activating.Can also be not activate when providing, follow, in UWB label, the covering model that target vehicle enters UWB base station
When enclosing interior, activated by UWB base station.After wherein UWB is activated all the time in real time or the cycle transmission first framing signal.
S102:And judged to described UWB tag location according to multiple described first location information that described UWB label sends
Whether stable：
It should be understood that UWB label often sends first location information, this first location information can be by least three
UWB base station is received, and parking lot management server arrives according to the predeterminated position of at least three UWB base stations and this first location information
The arrival time reaching each UWB base station carries out one-time positioning to this UWB label.UWB label is in the coverage of a plurality of UWB base stations
Inside ceaselessly send several first location informations, the UWB label position that parking lot management server can be in the hope of correspondence for several times,
And corresponding positioning time.If in default time span, the dispersion degree of several positions is low, and such as variance is less than pre-
If value, then judge that this UWB label is stable.It should be understood that in addition to variance, any two value differences can also be taken to be less than preset value,
No matter how method is reaches the low purpose of dispersion degree, here does not limit.
S103:Determine the parking spot that the last corresponding position of stable state occurring is described target vehicle.
It should be understood that except it needs to be determined that in addition to the parking spot of target vehicle, due to UWB label small volume not simultaneously
As UWB board units are fixedly mounted on vehicle, simultaneously UWB label be also possible to as pre-payment in different parking lots or
, therefore there is the possibility that UWB label is carried with by user in the carrier of trade company's Free parking.Need therefore when positioning to it
Consider is placed in target vehicle, and is carried with two kinds of possibility.
Therefore before step S103, also include：
If judging that described UWB label occurs, after stable state, being constantly in shakiness according to multiple described first location informations
Determine state to moving to outside parking area, then judge that described UWB label separates with described target vehicle；
If judging that described UWB label occurs after stable state according to multiple described first location informations, in pre-determined stability
Interior be in stable state all the time, then judge that described UWB label and described target vehicle do not separate.
Easy to understand, UWB label is because sending the first positioning letter all the time in the coverage of a plurality of UWB base stations
Number, the electricity of UWB label can exhaust quickly.After therefore in determination target vehicle, stop over is good, setting UWB label is the second work
Make state.Wherein second working condition, may be off this UWB label so as to not retransmit the first framing signal.Can also be
Increase the transmission interval of the first framing signal, to be checked measure its motion after, activation UWB label is normal again sends the first positioning letter
Number.
Based on such scheme, if described UWB label separates with described target vehicle, move to delimitation in described UWB label
Parking area outside, before leaving the coverage of a plurality of UWB base stations, corresponding UWB label is set to the second working condition.
If judging, described UWB label and described target vehicle do not separate, and directly UWB label are arranged to the second working condition.Cause
This judge UWB label taken away with oneself by user or drop target vehicle in after, the second working condition can be arranged to faster,
The kwh loss of UWB label can be reduced.
Using this programme, solve the parking spot identification problem of the target vehicle without UWB board units, be conducive to be
System quickly spreads out, and reduces cost of labor.
It should be understood that in another embodiment, in addition to the target vehicle getting UWB label in entrance, also include
User's vehicle of UWB board units has been fixedly mounted on vehicle.Wherein it is mounted with that user's vehicle of UWB board units is fixed
The function of position and UWB label are essentially identical, including：
S201:Receive UWB board units in real time or the second framing signal of sending of cycle, wherein said second framing signal
Be the user's vehicle being provided with UWB board units after sailing parking lot into, described UWB board units be activated after send；
S202:Described UWB board units are judged according to multiple described second location information that described UWB board units send
The corresponding position of stable state finally occurring is the parking spot of described user's vehicle：
In addition, the method also includes：
S203:The parking spot of the parking spot according to described target vehicle and described user's vehicle is to described parking lot
Dead ship condition is recorded.
It should be understood that parking lot both includes having got the target vehicle of UWB label, also include that to be provided with UWB vehicle-mounted
User's vehicle of unit, it is therefore desirable to the data unification different to two parts is managed, obtains the parking of target vehicle simultaneously
Position and the parking spot of user's vehicle.Easy to understand, parking lot management server can obtain UWB mark by UWB base station
The mark signed and the mark of UWB board units.In order to distinguish management, the mark of UWB label adopts the first rule encoding, described
The mark of UWB board units adopts Second Rule to encode, and wherein said first rule is different with Second Rule.Wherein first rule
Different with Second Rule can be that coded system is different or flag is different, as long as can substantially distinguish here,
Do not do and limit further.
In further embodiment, and it is provided with to the target vehicle having got UWB label by parking lot management server 1
On the basis of user's vehicle unified management of UWB board units.
Judging whether there are other vehicles on the last corresponding position of described stable state occurring, if having, judging to correspond to
Described UWB tag state be abnormal.
Judge whether the last corresponding position of described stable state occurring is parking stall position, if it is not, then judging corresponding
Described UWB tag state is abnormal.
When state UWB label is abnormal, then parking lot management server notifies parking lot management personnel to carry out
Artificial treatment, excludes risk in time and corrects mistake, improve the efficiency of management, enhance the service experience of user.
In further embodiment, present invention also offers a kind of parking lot management server based on UWB technology, including：
