[0034] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and steps, nor must they be executed in the order described. For example, some steps can be decomposed, and some steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0035] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Figure 1The present invention is a system block diagram showing a parking space matching method and device for a parking lot according to an exemplary embodiment.

[0037] In the system 100 of the parking space matching method and device for parking lots, the server 105 may be a server that provides various services, such as a background management server (only as an example) that provides support for the parking space matching system of the parking lot operated by the user using the terminal devices 101, 102, 103 (including the target parking space terminal and the closest vehicle terminal) through the network 104. The background management server may analyze and process the received parking space matching request and other data, and feed back the processing results (such as matching notification - only as an example) to the target parking space terminal and the closest vehicle terminal.

[0038] The server 105 can, for example, determine a target parking space terminal whose parking space occupancy identifier indicates an empty parking space; receive the closest vehicle terminal returned by the target parking space terminal, where the closest vehicle terminal is determined by the target parking space terminal from among the multiple vehicle terminals to be matched based on RSSI values ​​sent by the multiple vehicle terminals to be matched; determine the centroid position of the closest vehicle terminal based on RSSI values ​​between the closest vehicle terminal and multiple positioning Bluetooth beacons; determine the target channel where the target parking space terminal is located; calculate the distance between the centroid position of the closest vehicle terminal and the target channel to obtain a target distance; if the target distance is less than a distance threshold, determine that the target parking space terminal and the closest vehicle terminal are matched, and send a matching notification to the target parking space terminal and the closest vehicle terminal so that the closest vehicle terminal can drive to the parking space where the target parking space terminal is located to park.

[0039] The server 105 may be a physical server, or may be composed of multiple servers. The server 105 may be, for example, Figure 5 The system framework of the parking lot matching management server 502 is shown. Figure 5 As shown, the management server 502 can be used to manage and control multiple area managers 504, and the multiple area managers 504 are set in multiple preset areas of the parking lot. Each area manager 504 is used to integrate the information of the parking space occupancy identifier and the RSSI value sensed by the parking space detector 508 (such as a video detector, an ultrasonic detector) in its corresponding area and upload it to the management server 502. The parking space detector 508 can be installed, for example, in front of each parking space to identify whether the parking space is an empty parking space, and upload the occupancy identifier indicating whether the parking space is an empty parking space to the area manager 504. The parking space detector 508 can also be integrated with the display screen of the parking space, and can also be integrated with a Bluetooth beacon.

[0040] The Bluetooth beacon 506 can be installed in front of the parking space, send Bluetooth broadcast information, calculate the RSSI value received by the Bluetooth terminal device 510, and send the RSSI value to the vehicle terminal to be matched (i.e., the Bluetooth terminal device 510). The Bluetooth terminal device 510 is the vehicle-mounted device or handheld device (smartphone) of each vehicle terminal to be matched.

[0041] Figure 2 1 is a flowchart of a parking space matching method for a parking lot according to an exemplary embodiment. The parking space matching method for a parking lot provided in the embodiment of the present disclosure can be executed by any electronic device with computing and processing capabilities, such as terminal devices 101, 102, 103 and / or server 105. In the following embodiments, the server execution method is used as an example for illustration, but the present disclosure is not limited thereto. The parking space matching method for a parking lot provided in the embodiment of the present disclosure may include steps S202 to S212.

[0042] like Figure 2 As shown, in step S202, a target parking space terminal whose parking space occupancy identifier indicates an empty parking space is determined.

[0043] In the disclosed embodiment, the placeholder identifier of each parking space can be recorded. For example, when a vehicle T1 that has been parked in a parking space B1 in a parking lot is about to leave, the owner of the vehicle T1 will receive the placeholder identifier update information sent by the vehicle terminal after clicking the "I want to leave" button on the vehicle terminal, and then update the placeholder identifier of the parking space B1 where the vehicle T1 was originally located, so that the placeholder identifier indicates an empty parking space. For another example, each target parking space terminal is configured with a distance measuring device. When the distance measuring device detects that there is no parking space in the parking space where the target parking space terminal is located (for example, the measured distance is greater than the distance threshold), the target parking space terminal reports to the server that the parking space occupancy identifier of the target parking space terminal is 0 (for example, 0 indicates an empty parking space, and 1 indicates an occupied parking space).

[0044] In a parking lot, each parking space can be equipped with a Bluetooth beacon, such as Figure 6 The parking space is marked as B and the vehicle is marked as T. For example, when the parking space terminals of parking spaces B1 and B2 return the occupancy identifier as an empty parking space, B1 and B2 are determined as target parking space terminals.

[0045] In step S204, the closest vehicle terminal returned by the target parking space terminal is received, where the closest vehicle terminal is determined by the target parking space terminal from among the multiple vehicle terminals to be matched according to RSSI values ​​sent by the multiple vehicle terminals to be matched.

[0046] Among them, the target parking space terminal can send Bluetooth broadcast information; receive the RSSI (Received Signal Strength Indication) values ​​returned by K to-be-matched vehicle terminals in response to the Bluetooth broadcast information, where K is an integer greater than 0; and determine the to-be-matched vehicle terminal corresponding to the minimum value of the received RSSI value as the closest vehicle terminal. The RSSI value is mainly used for distance measurement between the transmitter and the receiver. Its ranging theory is: determine the distance based on the received signal energy intensity, and through the attenuation model between the signal and the distance, the distance between the nodes can be calculated.

[0047] Each parking terminal may be provided with a Bluetooth beacon, which is turned on to send Bluetooth broadcast information when the parking space identifier of the parking terminal indicates an empty parking space. For a vehicle in the parking lot, the owner of the vehicle may turn on the Bluetooth device by operating the vehicle terminal to be matched to receive Bluetooth broadcast information.

[0048] In step S206, the centroid position closest to the vehicle terminal is determined according to the RSSI values ​​of the closest vehicle terminal and multiple positioning Bluetooth beacons.

[0049] In the embodiment of the present disclosure, a weighted centroid positioning algorithm can be used to process the RSSI values ​​of the closest vehicle terminal and multiple positioning Bluetooth beacons to obtain the centroid position closest to the vehicle terminal. The multiple positioning Bluetooth beacons can be, for example, Bluetooth beacons set at any number of locations in the parking lot and in a normally open state, regularly sending Bluetooth broadcast information and receiving RSSI values ​​returned by the closest vehicle terminal, and returning the multiple positioning Bluetooth beacons and the RSSI values ​​of the closest vehicle terminal to the execution subject of the embodiment of the present disclosure (such as server 105) to calculate the centroid position closest to the vehicle terminal.

[0050] Assume that there are multiple positioning Bluetooth beacons D 1 (x d1 ,y d1 )、D 2 (x 2 ,y 2 )、D 3 (x 3 ,y 3 )、D 4 (x 4 ,y 4 )、D 5 (x 5 ,y 5 )、D 6 (x 6 ,y 6 ), see Figure 7 As shown. Then the centroid position T(x, y) closest to the vehicle terminal can be expressed as shown in the calculation method of formula (1) and (2).

[0051]

[0052]

[0053] Wherein, i is the serial number of the positioning Bluetooth beacon, 1≤i≤n, and n is the number of positioning Bluetooth beacons. In this example, n=6. i is the influence weight of the ith positioning Bluetooth beacon on the closest vehicle terminal, which is obtained by the RSSI value returned by each positioning Bluetooth beacon from the closest vehicle according to the calculation method of the following formula (3).

[0054]

[0055] Among them, RSSI max It is the maximum value of the RSSI value returned by each positioning Bluetooth beacon to the closest vehicle. RSSI min The minimum RSSI value returned by each positioning Bluetooth beacon closest to the vehicle. i It represents the RSSI value returned by the closest vehicle received by the current i-th Bluetooth beacon. max -RSSI min When i The value is 1.

[0056] In step S208, the target channel where the target parking space terminal is located is determined.

[0057] In the embodiment of the present disclosure, the channel information matching the target parking terminal can be searched in the preset database to be used as the target channel where the target parking terminal is located. The preset database may, for example, record the mapping relationship between each target parking terminal and the channel information where the target parking terminal is located. The channel information may, for example, be represented by a straight line equation. Figure 6 As shown, channel 1 is the target channel where the target parking space terminal B1 is located, but is not the target channel where the target parking space terminal B2 is located.

[0058] In another embodiment, the target channel where the target parking space terminal is located can also be determined based on the location information of the Bluetooth beacons set at both ends of each channel. Figure 6 As shown, Bluetooth beacons C1 and C2 are set at both ends of channel 1. Figure 7 As shown, the target parking space terminal is bound in advance with the identifiers of the Bluetooth beacons at both ends of the lane where it is located. For the Bluetooth beacons at both ends of the lane, the position information of the Bluetooth beacons at both ends of the lane can also be obtained by positioning using the methods shown in equations (1) and (2), and then the target channel can be accurately positioned based on the position information of the Bluetooth beacons at both ends of the lane.

[0059] For another example, if unavailable information of m positioning Bluetooth beacons among multiple positioning Bluetooth beacons is received when executing step S206, m positioning Bluetooth beacons set at both ends of the channel can be replaced by m positioning Bluetooth beacons to obtain updated multiple positioning Bluetooth beacons; m is an integer greater than 0; the center of mass position closest to the vehicle terminal is determined based on the RSSI values ​​of the closest vehicle terminal and the updated multiple positioning Bluetooth beacons.

[0060] In step S210, the distance between the centroid position closest to the vehicle terminal and the target channel is calculated to obtain the target distance.

[0061] In the embodiment of the present disclosure, it is assumed that the endpoint positions of the two ends of the target channel (if Bluetooth beacons are set at both ends of the target channel, the position information of the Bluetooth beacons) are: C1 = (x c1 ,y c1 )、C2=(x c2 ,y c2 ), then the equation of the straight line where the target channel is located can be expressed as At the same time, the target distance d can be expressed as formula (4).

[0062]

[0063] In step S212, if the target distance is less than the distance threshold, the target parking space terminal and the closest vehicle terminal are determined to match, and a matching notification is sent to the target parking space terminal and the closest vehicle terminal so that the closest vehicle terminal drives to the parking space where the target parking space terminal is located for parking.

[0064] In the disclosed embodiment, the distance threshold may range from 100 cm to 150 cm. In this step, if the target distance is less than the distance threshold, it can be considered that the vehicle corresponding to the closest vehicle terminal is traveling on the target channel. Figure 6 As shown, the target parking space terminal B1 is most closely matched with the closest vehicle terminal T1, and the target parking space terminal B2 does not match T1. This is because, although T1 is equidistant from B1 and B2, T1 is on the passage in front of B1, so T1 matches B1. By sending a matching notification to the target parking space terminal and the closest vehicle terminal, the target parking space terminal will display "Occupied by XX vehicle" on its configured parking space display screen after receiving the matching notification, and the target vehicle terminal will display "XX parking space has been locked, you are about to enter, please pay attention" on the display screen configured by the target vehicle terminal after receiving the matching notification.

[0065] According to the parking space matching method of the parking lot provided by the embodiment of the present disclosure, for the target parking space terminal whose parking space occupancy identifier indicates an empty parking space, the closest vehicle terminal is first determined among the multiple vehicle terminals to be matched according to the RSSI values ​​sent by the multiple vehicle terminals to be matched, so as to ensure that the closest vehicle terminal corresponds to the vehicle that needs to find an empty parking space and is currently closest to the target parking space terminal. At the same time, based on the centroid position of the closest vehicle terminal and the target distance of the target channel where the target parking space terminal is located, it is determined whether the vehicle corresponding to the closest vehicle terminal is located on the target channel where the parking space corresponding to the target parking space terminal is located, so that the target parking space terminal and the closest vehicle can be quickly matched to achieve rapid matching of parking spaces. At the same time, the parking space matching method of the parking lot of the present application only relies on the RSSI value of the Bluetooth beacon for calculation, and has the advantages of simple construction scheme, simple logic and cost saving.

[0066] Figure 3 The flowchart of a parking space matching method of a parking lot according to another exemplary embodiment is shown. The parking space matching method of the parking lot provided in the embodiment of the present disclosure may include steps S302 to S304.

[0067] like Figure 3 As shown, in step S302, if the target distance is greater than or equal to the distance threshold, the vehicle to be matched with the target parking space terminal and having the second smallest RSSI value returned by the target parking space terminal is received.

[0068] In step S304, the to-be-matched vehicle is determined as the updated closest vehicle terminal, so that the target parking space terminal and the updated closest vehicle terminal are matched according to the distance between the updated closest vehicle terminal and the i-th target channel.

[0069] In another embodiment, if the target distance is greater than or equal to the distance threshold, the execution may be returned to the default setting after a preset waiting time. Figure 2 In the embodiment, steps S202 to S212 are performed until the closest vehicle terminal matching the target parking space terminal is obtained.

[0070] Figure 4 FIG. 4 is a flow chart of a parking space matching method for a parking lot according to another exemplary embodiment. The parking space matching method for a parking lot provided in the embodiment of the present disclosure may include steps S402 to S304.

[0071] In the embodiment of the present disclosure, the target parking space terminal includes a first target parking space terminal and a second target parking space terminal. Figure 4As shown, in step S402, if the closest vehicle terminal matching the first target parking space terminal and the closest vehicle terminal matching the second target parking space terminal are the same vehicle terminal to be matched, a first RSSI value of the closest vehicle terminal and the first target parking space terminal, and a second RSSI value of the closest vehicle terminal and the second target vehicle terminal are obtained.

[0072] In step S404, if the first RSSI value is less than the second RSSI value, the closest vehicle terminal is taken as the first closest vehicle terminal and matched with the first target parking space terminal.

[0073] In this embodiment, the vehicle to be matched with the second target parking space terminal having the second smallest RSSI value returned by the second target parking space terminal can also be received to obtain the second closest vehicle terminal; the matching of the second closest vehicle terminal and the second target parking space terminal is determined based on the distance between the second closest vehicle terminal and the target channel where the second target parking space terminal is located.

[0074] According to the parking lot parking space matching method provided by the embodiment of the present disclosure, at the first target parking space terminal (for example Figure 8 B) and the second target parking space terminal (e.g. Figure 8 A) matches the same closest vehicle terminal (e.g. Figure 8 When the first RSSI value and the second RSSI value are compared, the closest vehicle terminal is matched with the target parking space terminal (the first target parking space terminal or the second target parking space terminal) with a smaller RSSI value (i.e., B matching 1), and at the same time, for another unmatched second target parking space terminal, the to-be-matched vehicle (e.g., the second target parking space terminal) with the second smallest RSSI value is matched. Figure 8 Vehicle 2), determine the second closest vehicle terminal, and compare the distance between the second closest vehicle terminal and the channel where the second target parking space terminal is located with the distance threshold. When the distance is less than the distance threshold, it is considered that the second closest vehicle terminal matches the second target parking space terminal. This can solve the problem of multiple parking spaces matching the same closest vehicle terminal, realize parallel matching calculation of multiple target parking space terminals and multiple vehicle terminals, improve matching efficiency, and reduce parking waiting time.
