It is understood that these embodiments are given solely for the purpose of enabling those skilled in the art to better understand and to practice the present disclosure, and are not intended to limit the scope of the present disclosure in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
The present disclosure provides a parking management system. Referring to fig. 1, fig. 1 is an exemplary schematic diagram illustrating a parking management system 100 according to an embodiment of the present disclosure. As shown in fig. 1, the parking management system 100 may include a sensing unit 110 and a server 120. The sensing unit 110 is used for transmitting first parking space information when the vehicle is parked in the parking space. The server 120 is configured to obtain the first location information and the position information of the vehicle, obtain the vehicle information of the vehicle according to the first location information and the position information of the vehicle, and bind the first location information and the vehicle information, so as to start parking management.
Specifically, when the sensing unit 110 senses that the vehicle is parked in the parking space, the parking space information corresponding to the parking space is sent to the server 120, wherein the parking space information may refer to a number of the parking space or a number of the sensing unit, for example. To start parking management, the server 120 may acquire position information of the vehicle after the vehicle enters the parking lot, and also acquire parking space information transmitted from the sensing unit 110 if the vehicle is parked in the parking space. And the server 120 may obtain vehicle information of the vehicle, such as a license plate number, and bind the vehicle information with the parking space information by analyzing the position information of the vehicle and the acquired parking space information.
It should be noted that the parking management system 100 may be applied to parking management of parking areas in order to establish unattended parking areas. The parking area includes an above-ground parking lot, an underground parking lot, a roadside, and the like.
According to an embodiment of the present disclosure, the sensing unit 110 may be configured to transmit the first parking space information when the vehicle is parked in the parking space in the following manner: acquiring the magnetic field variation generated when the vehicle stops in the parking space; and sending the first parking space information according to the magnetic field variation.
In this embodiment, each parking space in the parking lot is equipped with a corresponding sensing unit 110, and when a vehicle enters the parking space, the sensing unit 110 senses the change of the magnetic field and transmits parking space information according to the specific change of the magnetic field. Specifically, the sensing unit 110 may send the first vehicle location information when the magnetic field variation is greater than a preset threshold, where the preset threshold may be set manually according to experience and needs.
In addition, the sensing unit 110 may include at least one magnetic field sensor, which may be disposed in the parking space and used for acquiring a magnetic field variation caused when the vehicle is parked in the parking space. The at least one magnetic field sensor may also be disposed at any other position where the vehicle can be accurately sensed to enter the parking space, such as below (buried) the parking space, or at one side of the parking space, or above the parking space, which is not limited herein. In addition, the number of magnetic field sensors can be set, for example, according to the size and position of the vehicle.
Referring to fig. 2, fig. 2 shows an exemplary schematic diagram of a parking management system 200 according to another embodiment of the present disclosure. The parking management system 200 shown in fig. 2 is different from the parking management system 100 shown in fig. 1 in that the parking management system 200 further includes a geomagnetic gateway 210, a bluetooth base station 220, and a bluetooth gateway 230.
According to an embodiment of the present disclosure, the server 120 may be configured to acquire the position information of the vehicle in the following manner: establishing a connection with an on-board unit of the vehicle; the position information of the vehicle obtained by the cooperation of the on-board unit and the Bluetooth base station is acquired from the on-board unit. Specifically, the server 120 may be configured to establish a connection with the vehicle in the following manner: broadcasting and sending server information; acquiring a connection request sent after the vehicle-mounted unit receives the server information; and establishing connection with the vehicle-mounted unit.
In this embodiment, in a parking area such as a parking lot, the server 120 may continuously transmit server information required to establish a connection with the server 120, such as an ip and a port of the server, in a broadcast manner through the bluetooth gateway 230. When a vehicle enters a parking lot, an on-board unit, such as an OBU, on the vehicle may receive the server information. After receiving the server information, the obu may process the connection request connected to the server 120 through the bluetooth gateway 230 and convert the connection request into a connection frame of tcp/ip protocol, and send the connection frame to the server 120. The server 120 may then establish a connection with the on-board unit. After establishing the connection, the server 120 may acquire the location information of the vehicle from the on-board unit through the bluetooth gateway 230.
The position information is information used to obtain position coordinates of the vehicle. The position information may be obtained by the on-board unit in cooperation with the bluetooth base station 220, and may be, for example, a Received Signal Strength Indication (RSSI) value.
In particular, bluetooth base station 220 may include a plurality of beacons. The plurality of beacons may be arranged within a parking area, such as a parking lot. In particular, the beacon may be positioned on the ground, on a support pole, etc. Wherein, each beacon is internally provided with a signal transmitting module, a signal receiving module and a signal processing module. The signal transmitting module and the signal receiving module are respectively used for transmitting and receiving Bluetooth signals, and the signal processing module can process the Bluetooth signals. In this embodiment, for example, at least three beacons are provided in the parking area of the parking lot.
When a vehicle enters a parking lot, a Bluetooth module in the vehicle-mounted unit can continuously receive an inquiry signal broadcasted by a beacon, and the vehicle-mounted unit can measure and calculate an RSSI value under each beacon in real time. And the on board unit transmits the obtained RSSI value to the server 120 through the bluetooth gateway 230 via the wifi network.
The bluetooth gateway 230 may be used for interconnection of a wide area network and also for interconnection of a local area network. Thus, bluetooth gateway 230 and server 120 may communicate in two ways:
1. when the server is deployed in the local area network of the parking lot, the Bluetooth gateway is connected with the router through WIFI or a wired network, and the server communicates with the router in the local area network.
2. When the server is deployed at the cloud end, the Bluetooth gateway is connected with the router through WIFI or a wired network, and the server which is brought to the cloud end through the wired network is accessed through the router, or the server is directly connected with the cloud end through the 4G network module.
According to an embodiment of the present disclosure, the server 120 may be configured to acquire the vehicle information of the vehicle from the first location information and the location information of the vehicle in the following manner: determining that the vehicle corresponds to the parking space according to the first parking space information and the position information of the vehicle; vehicle information of a vehicle is acquired.
In this embodiment, the server 120 may determine the correspondence relationship between the vehicle and the parking space according to the first vehicle location information and the position information of the vehicle obtained as described above, so as to obtain the vehicle information of the vehicle parked in the parking space. The on-board unit of the vehicle may include an ESAM (embedded security control module) that may be used to store the vehicle information, which may include a license plate number.
Further, the server 120 may be configured to determine that the vehicle corresponds to the space based on the first location information and the location information of the vehicle by determining a plurality of location coordinates of the vehicle based on the location information of the vehicle via a ranging algorithm; determining a parking space coordinate corresponding to the parking space according to the first parking space information; and determining that the vehicle corresponds to the parking space according to the position coordinates and the parking space coordinates.
In order to determine the correspondence relationship between the vehicle and the parking space, the server 120 first calculates the position coordinates of the vehicle from the position information of the vehicle obtained as described above.
Specifically, after the server 120 receives the RSSI value, the position coordinates of the vehicle are calculated by a distance measurement algorithm such as KNN algorithm according to the RSSI value of the vehicle. It should be understood that, during the vehicle traveling process, the server 120 also continuously receives and calculates the RSSI value sent by the vehicle-mounted unit, so that the position coordinates of the vehicle can be obtained and stored in real time, and therefore the moving track of each vehicle can be known.
In order to determine the corresponding relationship between the vehicle and the parking space, the server 120 further needs to obtain the corresponding parking space coordinates according to the first parking space information obtained as described above. Since the server 120 already has the corresponding coordinates of all the parking spaces in the parking lot. The server 120 may find the parking space coordinates corresponding to the numbered parking spaces according to the first parking space information, for example, the parking space number.
After obtaining the movement trajectory (position coordinates) of the vehicle and the parking space coordinates of the parking space, the server 120 may be configured to determine that the vehicle corresponds to the parking space according to the plurality of position coordinates and parking space coordinates as follows: when a difference between the parking space coordinate and at least one of the plurality of position coordinates is within a preset range, the vehicle corresponds to the parking space.
Specifically, after the vehicle enters the parking lot, a plurality of position coordinates are generated along with the movement of the vehicle, and if the vehicle enters a parking space, the position coordinates of the vehicle moving to the parking space correspond to the parking space coordinates. In addition, the server 120 stores position coordinates of all vehicles. Therefore, after receiving the first parking space information sent by the sensing unit 110 through the geomagnetic gateway 210, the server 120 finds the parking space coordinates corresponding to the parking space where the parking space information is sent, and then compares the parking space coordinates with the position coordinates of all vehicles in the server 120. When the vehicle position coordinate with the difference between the vehicle position coordinate and the parking space coordinate within the preset range is found, the vehicle position coordinate corresponding to the parking space coordinate can be determined, and then the vehicle corresponding to the parking space can be determined by determining the vehicle to which the vehicle position coordinate belongs.
At this time, the server 120 may send an inquiry command to inquire the vehicle information of the vehicle, and after obtaining the vehicle information, may determine the vehicle information corresponding to the parking space, for example, the license plate number corresponding to the parking space. The server 120 can bind the parking space to the license plate, so that parking management can be started, for example, a toll meter is started. Of course, the server 120 may also obtain the vehicle information after the server establishes connection with the vehicle, and directly use the vehicle information to bind with the parking space after determining the vehicle corresponding to the parking space by the above method.
According to an embodiment of the present disclosure, the sensing unit 110 may also be configured to send second parking space information when the vehicle drives out of the parking space; the server 120 may be configured to receive the second parking space information and unbind the first parking space information from the vehicle information according to the second parking space information, so as to end the parking management.
In this embodiment, when the vehicle parked in the parking space leaves the parking space, the sensing unit 110 also senses the magnetic field change and transmits the parking space information to the server 120. The parking space information may be, for example, a unbinding signal, that is, the server 120 is informed that the first parking space information sent by the sensing unit 110 when the vehicle is parked in the parking space can be unbound from the vehicle information, that is, the vehicle is unbound from the corresponding parking space. So that the parking management, for example, the stop of the toll meter can be ended. Therefore, the server 120 can calculate the difference between the leaving time and the parking time of the vehicle corresponding to the parking space, and therefore the actual parking time of the vehicle can be obtained as the calculation reference of the payment operation.
It should be noted that, when the vehicle and the parking space are unbound, the server 120 may clear the movement track (position coordinates) of the vehicle or otherwise store or backup the movement track to another location, so as to avoid using the position coordinates of the vehicle currently parked in the parking space when determining the corresponding relationship between the position coordinates of the vehicle and the parking space coordinates for the same parking space next time.
Referring to fig. 3, fig. 3 shows an exemplary schematic diagram of a parking management system 300 according to yet another embodiment of the present disclosure. As shown in fig. 3, the parking management system 300 is different from the parking management system 200 shown in fig. 2 in that the parking management system 300 includes a sensing unit 310, and the sensing unit 310 includes a wireless communication module 311, and the wireless communication module 311 is configured to transmit the first parking space information to the server 120. Specifically, the wireless communication module is a bluetooth module, and thus, the sensing unit 310 can communicate with the server 120 through the bluetooth gateway 230. Except for the differences described above, the parking management system 300 shown in fig. 3 operates on the same principle and functions as the parking management system 200 shown in fig. 2, and thus, the details are not repeated herein.
In one implementation scenario, the parking management system may also communicate with an electronic device so that the relevant person may view the movement trajectory of the vehicle. The electronic device may include a mobile terminal such as a mobile phone, a tablet computer, a notebook computer, a palm top computer, a Personal Digital Assistant (PDA), a navigation device, a wearable device, a smart band, a pedometer, and a fixed terminal such as a Digital TV, a desktop computer, and the like.
When the vehicle enters the parking lot and the server obtains the position coordinates (moving track) of the vehicle, the position coordinates can be transmitted to the electronic equipment in real time in a wireless or wired mode to be displayed.
Specifically, when the electronic device is a mobile terminal, such as a mobile phone, the vehicle movement track may be transmitted to the mobile phone in a wireless manner, so that the vehicle movement track may be displayed on the mobile phone APP in real time. And the position coordinates of the vehicle at each moment are recorded in the server, so that the user can inquire the historical track according to the requirement.
In addition, when the electronic device is a fixed terminal, such as a desktop computer, the vehicle movement track may be transmitted to the server wirelessly or by wire, where the desktop computer may also be used as a management device disposed in a parking lot, and may provide a manager to monitor or a user to search for a parking space. For example, a parking lot manager can check the moving track of the vehicle in real time, so that the vehicle is prevented from randomly parking. Further, the parking management system 200 may further include: and the camera is arranged in the parking area and connected with the server so as to be used for checking the parking position of the vehicle in the parking area. Therefore, the parking lot manager can call the video data of any camera arranged in the parking lot according to the moving track of the vehicle, so that the parking and traveling conditions of the vehicle can be directly seen from the monitor.
After the vehicle is parked in the parking space, the server determines and binds the parking space information and the vehicle information, the user can see the vehicle and the license plate number corresponding to the parking space on the mobile phone APP, and whether the binding is true or not is confirmed through comparison. In addition, when the car owner forgets the parking space, the stored car moving track can be checked through the mobile phone to find the car. Furthermore, the server can give the information of the empty parking spaces according to the service conditions of the parking spaces in the parking lot, so that a user who does not find the parking spaces can search the empty parking spaces according to the information to save the time for searching the parking spaces. Furthermore, the vehicle movement track can also be used as a reference when planning the parking lot route in the future.
