UWB base station 2 is for receiving the radio positioning signal of UWB electronic tag 1 transmitting and obtaining the parameter value of the relatively described vehicle in each UWB base station 2 according to this radio positioning signal respectively.The parameter of UWB base station mentioned here relative vehicle can be the various parameters that can be gone out vehicle location by calculated with mathematical model, preferred received signal strength (RSSI), time of arrival (toa) (TOA), the time of advent poor (TDOA), angle of arrival (AOA), the more preferably time of advent poor (TDOA).
Compartment of terrain, all UWB base stations 2 is arranged in parking area, and parking area can be road-surface concrete field, passenger traffic station, underground parking etc.The layout of UWB base station 2 can be arranged according to the layout in concrete parking lot, as Fig. 3-5 respectively illustrate in some road-surface concrete fields, passenger traffic station, UWB base station, underground parking layout scenarios, wherein circle represents UWB base station, and each rectangular area represents a parking stall.
The processing unit (not shown) of navigation system is used for according to the positional information from the parameter value determination vehicle of at least three UWB base stations, and the positional parameter value namely for being determined UWB base station substitutes into Mathematical Modeling, determines the positional information of vehicle.This processing unit can be an independently device, also can be arranged at dominant base or background server 3, if self-contained unit then should possess communication function, to realize the communication of itself and base station and background server.
When selecting RSSI or TOA as positional parameter, determine the positional information of target (i.e. vehicle) by circles/spheres location model.When selecting TDOA as positional parameter, determine the positional information of target by hyperbola/face location model.When selecting AOA as positional parameter, determine the positional information of target by angle location model.
1, circles/spheres location model:
Circular location is the target localization to two dimensional surface, RSSI or TOA of destination node (being namely loaded with the vehicle of UWB electronic tag) framing signal is received by witness mark node (i.e. UWB base station), calculate the distance of reference node to destination node thus, can determine a circle by destination node to the distance d of reference node, destination node one is positioned on this circle.When having the individual reference node of N (N>=3) to participate in ranging localization simultaneously, the intersection point between multiple circle is exactly the position of corresponding target, as shown in Figure 6.Spherical location is then locate three-dimensional realization of goal.
Define one group of circular equation thus:
( x - x i ) 2 + ( y - y i ) 2 = r i . . . . . . i = 1,2,3 .
Solve the coordinate figure that above-mentioned equation group just can obtain destination node.2 equations are only needed to try to achieve non trivial solution in theory, but in practice due to the existence of various error source, need the equation to more than 3 to carry out position that minimum variance or maximum likelihood process just can obtain destination node.
At three dimensions, the position coordinates of destination node N is (x, y, z), by calculating the distance ri between destination node N and reference node Ni, thus obtain taking Ni as the centre of sphere, take ri as the sphere of the radius of a ball, then N is positioned at the intersection point of these spheres, obtains equation group:
( x - x i ) 2 + ( y - y i ) 2 + ( z - z i ) 2 = r i . . . . . . i = 1,2,3 , 4 .
The reference node choosing more than 4 is set up equation group and is calculated, and can calculate the position coordinates of destination node in three dimensions.
2, hyperbola/face location model:
This location model is the TDOA receiving same destination node framing signal by measuring different reference node, thus calculate the range difference of different reference node to destination node, one group of hyperbola can be determined by destination node to the range difference of any two reference nodes.When having the individual reference node of N (N>=3) to participate in range finding simultaneously, the intersection point between multiple hyperbola just obtains the estimation to target location.Compared with TOA, its key benefit is the response and the processing delay that do not need accurately to try to achieve reference node and destination node again, only requires that all clocks participating in the reference node measured are synchronous.
With reference to Fig. 7, in two dimensional surface, when the range difference when between reference node A and B and destination node X is d1, destination node must be positioned at A and B for focus, is on the determined hyperbola of solid line of d1 with the range difference perseverance of two focuses.When the range difference recording reference node A and C and destination node X is d2 simultaneously, just can obtain another group with A and C for focus, and the hyperbola represented with the solid line that the range difference perseverance of focus is d2 is to upper, two groups of hyp intersection points are the position of destination node.
3, angle location model
The geometrical principle of angle location model is that measurement target node is with LOS (line of sight, sighting distance) arrive the signal angle of reference node, destination node must be positioned on the straight line corresponding to this angle, namely utilizes a geometrical model of AOA Information locating.With reference to Fig. 8, when two reference node N1 and N2 record after target sends the angle of arrival of the LOS of signal simultaneously, the intersection point N of its corresponding two straight lines is the position at destination node place.
The angle of arrival that hypothetical reference node N1 and reference node N2 records the signal that destination node sends respectively is θ 1 and θ 2, then obtain equation group as follows:
tan ( θ 1 ) = x - x 1 y - y 1 tan ( θ 2 ) = x - x 2 y - y 2
Separate the coordinate figure that namely this equation group can obtain destination node.Can find out, angular surveying location model only needs two reference nodes, and certainly, the reference node number participating in location is more, and the redundancy of its data is higher, and the precision of location and success rate will be higher.
Video identification subsystem 4 and background server 3 communicate to connect, for passing through video tracking positioned vehicle and identifying vehicle identity information.Can the video identification equipment (camera) of position configuration video identification subsystem 4 such as near gateway, channel side between gateway and parking stall and parking stall as the case may be.
UWB base station, processing unit, background server and video identification subsystem preferably all configure the WIFI module with relay function, to realize stable radio communication.
The method realizing vehicle location comprises the following steps:
(1) entrance roadside unit (as 5.8GHZ roadside unit) wakes up (activation) the UWB electronic tag sailed on the vehicle of entrance, wake rear UWB electronic tag up and start locating module, as transmission and the receiver module of 6.5GHZ signal.Accordingly, when vehicle sails out of parking area outlet, the UWB electronic tag triggered on vehicle by Exit Road side unit closes locating module, enters park mode.The object of this step is in order to power saving, Cai only have the timing/of UWB electronic tag or not timing upon awakening to launch radio positioning signal (as 6.5GHZ signal);
(2) vehicle enters parking area, contained electronic tag timing/not timing sends radio positioning signal, UWB base station then in parking area receives this signal, and by receive this signal temporal information (can be calibration before original time information, also can be the information time of advent after calibration) be sent to described processing unit by WIFI, this processing unit can be self-contained unit, also can be arranged in dominant base or background server;
(3) position the Wireless clock synchronization on channel (6.5GHZ channel) between each base station in real time, make the clocking error between each base station be no more than 1ns.Specifically can send synchronization frame by the synchronization module in dominant base, after receiving synchronization frame from base station, realize clock synchronous by algorithm (as time data filtering algorithm);
(4) multiple base station (being no less than 3) is by receiving the 6.5GHz signal that returns of electronic tag, generate time of reception, and this time of reception is sent to described processing unit by WIFI or 6.5GHZ channel, processing unit calculates electronic tag vehicle position according to TDOA algorithm;
(5) described processing unit real-time tracking electronic tag vehicle position.
(6) further can also in the parking stall list of locations of the preset parking areas such as the dominant base of system or background server, parking stall list of locations comprises the center-of-mass coordinate of each corresponding region, parking stall, as in Fig. 9, A, B, C, D, E, F, G are rectangle parking stall, with the location parameter of rectangle center-of-mass coordinate as corresponding parking stall.When (such as in 10 seconds, change is no more than+-0.5m) after electronic tag vehicle position information does not change within a certain period of time, then think that it stops travelling, now by matching algorithm, vehicle identity information is mated with parking stall list of locations the corresponding relation obtaining vehicle and parking stall, thus determine each electronic tag vehicle place parking spot.The information such as license plate number, vehicle is contained, so can, by vehicle one_to_one corresponding to parking stall, facilitate car owner to search in system due in the locating information that electronic tag transmits.
(7) near road trackside recognition and tracking can also be carried out by video identification subsystem to vehicle further, video identification equipment can be arranged on gateway, travelling for vehicle between gateway and parking stall and parking stall.Gateway video identification equipment is responsible for carrying out Car license recognition to vehicle, uses for manager; For the Road side-looking identification equipment frequently that vehicle travels between gateway and parking stall, mainly follow the tracks of vehicle driving trace, and combining wireless positioning track, making up mutually can not overlay area.Video identification equipment near parking stall, mainly identify cover on parking stall whether stop there is vehicle, such as video camera irradiates ABCEDFG parking stall (as shown in Figure 10), (non-ly a kind of method is only had by background subtraction, here be citing), can judge that on ABCEDEFG, which has car, which is without car, determine vehicle parking position, and can room be determined.In Figure 10 rectangular area this parking stall of shadow representation on existing car.
(8) to video identification subsystem positioning result and UWB wireless location result treatment, can also distinguish on parking stall and have the vehicle of UWB electronic tag and the vehicle without UWB electronic tag further.Because video identification equipment identifiable design goes out vehicle parking parking stall, and wireless location technology can identify the Parking Stall of label vehicle, so remove in the vehicle parking parking stall that video identification recognition of devices goes out and have the Parking Stall of label vehicle, the parking spot that remaining is exactly without label vehicle.
(9) can also comprise further and carry out corresponding to the vehicle without UWB electronic tag with parking stall, facilitate manager to manage and search with car owner.Because entrance carries out car plate video identification to vehicle, vehicle running path has carried out video tracking to vehicle simultaneously, parking stall is also carried out video tracking to vehicle and mated, so can obtain at entrance without the number-plate number of label vehicle, so also can one_to_one corresponding without the number-plate number of label vehicle and its parking stall, place.
