Description

Technical Field

[0001] The present invention relates to the technical field of parking space monitoring, and in particular to a parking space monitoring system combining radar and geomagnetic technology. Background Art

[0002] With the acceleration of urbanization and the rapid growth of the number of motor vehicles, parking resource management has become a major problem in the transportation system. In busy city centers and large commercial complexes, parking lots often face problems such as unclear parking space occupancy, traffic congestion, and low parking efficiency. Surveys show that car owners spend an average of more than 15 minutes looking for parking spaces, which not only affects the car owner's experience, but also increases the backlog of vehicles on the road.

[0003] At present, some parking lots have introduced geomagnetic sensors to detect the status of parking spaces. Geomagnetic sensors determine whether a parking space is occupied by detecting the disturbance of the magnetic field by the vehicle, and have the advantages of low power consumption and simple maintenance. However, the detection accuracy of geomagnetic sensors has certain limitations in detecting multiple vehicles moving at the same time or non-metallic vehicles. In order to improve the accuracy of parking space monitoring, some parking lots choose to further install radar sensors on the basis of the installed geomagnetic sensors, and realize accurate monitoring of the parking space status through the coordination of geomagnetism and radar. However, installing radar in parking spaces results in high costs, and it is difficult to deploy on a large scale to all parking spaces. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The drawings described herein are used to provide a further understanding of the embodiments of the present invention, constitute a part of this application, and do not constitute a limitation of the embodiments of the present invention. In the drawings:

[0032] Figure 1 The present invention discloses a parking space monitoring system combining radar and geomagnetic technology. DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0034] Embodiment 1

[0035] See also Figure 1 , Figure 1 is a schematic diagram of the structure of a parking space monitoring system combining radar and geomagnetic technology disclosed in an embodiment of the present invention, wherein the system includes a radar monitoring module, a vehicle service module, a geomagnetic monitoring module, a communication module and a data processing module; wherein,

[0036] The radar monitoring module is arranged at the entrance and exit of the parking lot, and is used for real-time monitoring of the flow and direction of vehicles entering and leaving the parking lot, and obtaining the first monitoring data.

[0037] In an embodiment of the present invention, the radar monitoring module can be implemented based on millimeter wave radar or ultrasonic radar, which is not limited in the embodiment of the present invention; the first monitoring data acquired by the radar monitoring module includes but is not limited to the number of vehicles, driving direction (entering or leaving the parking lot), and the timestamp when the radar detects the vehicle.

[0038] In addition, it is understandable that, due to the high deployment cost of the radar monitoring module, the embodiment of the present invention effectively reduces the monitoring cost by only setting up the radar monitoring module at the entrance and exit of the parking lot.

[0039] The vehicle service module includes a reservation unit and a navigation unit.

[0040] Among them, the reservation unit is used for users to make reservations for parking spaces before the first preset time threshold when entering the parking lot. Specifically, the first preset time threshold refers to the earliest time value that can be reserved in advance of the estimated time of arrival at the parking lot determined when the user reserves a parking space. The value of the first preset time threshold is determined based on the statistical historical parking space reservation data. For example, if the first preset time threshold is set to 3 minutes, when the user wants to reserve a parking space when it is expected to arrive at the parking lot at 12:03, the user can use the reservation function of the reservation unit to reserve a parking space at the earliest at 12 o'clock, and enter the estimated time of arrival at the parking lot entrance when reserving a parking space. When the user does not enter, the time is defaulted to the time when the user selects the reservable parking space plus the first preset time threshold.

[0041] It is understandable that the value of the first preset time threshold is usually set to be relatively small, in order to improve the matching degree between the user's parking reservation situation and the user's actual parking demand and reduce the waste of reservation resources.

[0042] The navigation unit is used to determine the driving route from the parking lot entrance to the reserved parking space according to the user's reserved parking space after the user successfully reserves the parking space, so that the user can drive to the reserved parking space according to the driving route. The user's reserved parking space information, the estimated time of arrival at the parking lot entrance, and the driving route from the parking lot entrance to the reserved parking space are used as the first reservation data.

[0043] Since the signal inside the parking lot is usually weak, the navigation function of the navigation unit in the embodiment of the present invention is a navigation based on the local parking lot map, that is, an online network is not required to realize the navigation function.

[0044] Specifically, the layout of the parking lot, the location of the parking space, the channel information, the entrance and exit locations, etc. are preloaded in the navigation unit. When the user successfully reserves a parking space, the location information of the reserved parking space is associated with the location of the parking lot entrance, and the optimal driving path from the entrance to the parking space is generated for the user.

[0045] The geomagnetic monitoring module is embedded in each parking space and is used to monitor the parking space status in real time to obtain the second monitoring data.

[0046] Specifically, in the embodiment of the present invention, the geomagnetic monitoring module mainly adopts a Hall sensor or a magnetoresistive sensor, and is preferably embedded in the central area of ​​the parking space. The embodiment of the present invention does not limit the number of sensors and the embedded position of the geomagnetic monitoring module. The core function of the geomagnetic monitoring module is to determine the occupancy status of the parking space by sensing the disturbance of the geomagnetic field by the vehicle. The second monitoring data includes but is not limited to the currently monitored parking space identification, parking space status, and the specific time of the status change.

[0047] The communication module is used for uploading the first monitoring data, the first reservation data and the second monitoring data to the data processing module.

[0048] The data processing module is used to perform an analysis operation based on the first monitoring data and the first reservation data to obtain a first analysis result; and to analyze the first analysis result and the second monitoring data corresponding to the same parking space in the first analysis result using the parking space as an index to obtain a second analysis result.

[0049] Furthermore, the vehicle service module also includes an updating unit, which is used to update the parking space status of the parking lot according to the second analysis result.

[0050] Furthermore, the data processing module performs an analysis operation according to the first monitoring data and the first reservation data to obtain a first analysis result, including:

[0051] According to the first monitoring data, a vehicle that enters the parking lot entrance within a second preset time range before and after the estimated time of arrival at the parking lot entrance in the first reservation data is determined as a target vehicle, and the time when the target vehicle enters the parking lot is determined and recorded based on the first monitoring data. It is understandable that the estimated time of arrival at the parking lot entrance is not necessarily the same as the time when the user actually arrives at the parking lot entrance. Therefore, the second preset time range is set to represent the error range between the time when the user actually arrives at the parking lot entrance and the estimated time.

[0052] The target estimated time range for the target vehicle to arrive at the reserved parking space is calculated based on the driving route from the parking lot entrance to the reserved parking space in the first reservation data and the time when the target vehicle enters the parking lot, and is used as the first analysis result.

[0053] Specifically, after the driving route from the parking lot entrance to the reserved parking space is known, the time range for the target vehicle to travel from the parking lot entrance to the reserved parking space can be calculated based on the speed limit in the parking lot and the average speed of historical vehicles in the parking lot. On this basis, the target estimated time range for the target vehicle to arrive at the reserved parking space can be calculated by adding the time when the target vehicle enters the parking lot.

[0054] Furthermore, taking the parking space as an index, analyzing the first analysis result and the second monitoring data corresponding to the same parking space in the first analysis result to obtain the second analysis result includes:

[0055] The reserved parking space in the first analysis result is set as the target parking space, and the second monitoring data corresponding to the target parking space is determined as the target monitoring data.

[0056] Determine whether the target monitoring data shows a change in the parking space status from idle to occupied within the target estimated time range. If so, record the moment when the target parking space changes to an occupied state in the target monitoring data, and use the occupied state of the target parking space and the moment when it changes to the occupied state as the second analysis result.

[0057] Preferably, the geomagnetic monitoring module of the target parking space is set to perform a monitoring data acquisition operation within the target estimated time range or within a larger time range centered on the target estimated time range, and the monitoring data within the above time period is sent to the data processing module through the communication module to reduce the data processing amount of the data processing module and improve data processing efficiency.

[0058] Furthermore, the vehicle service module also includes a registration unit.

[0059] The registration unit is used for the user to input registration information, the registration information includes a vehicle identification, and the vehicle identification is used as login information when the user makes a parking space reservation.

[0060] Specifically, the user needs to register the vehicle information before using the functions provided by the vehicle service module. The above vehicle identification is an identification indicating the identity of the vehicle, which is unique and irreplaceable. Preferably, the vehicle identification can be the license plate number of the vehicle.

[0061] Furthermore, the first reservation data also includes vehicle identification information of the reserved parking space. Specifically, the user has completed the login operation when using the parking space reservation function, so after the user successfully reserves the parking space, the reservation information will be bound to the vehicle identification information.

[0062] Furthermore, the system also includes a position monitoring module. The position monitoring module is used to monitor whether the vehicle arrives at the parking lot entrance, and when the vehicle arrives at the parking lot entrance, the time when the vehicle arrives at the parking lot entrance is recorded as the third monitoring data; wherein the third monitoring data includes the time information of the vehicle arriving at the parking lot entrance monitored by the position monitoring module, and the vehicle identification information of the vehicle.

[0063] Specifically, in the embodiment of the present invention, the function of the position monitoring module is realized by a vehicle-mounted positioning device, wherein the vehicle-mounted positioning device includes but is not limited to a GNSS module, a Bluetooth module, and an RFID module, and the position monitoring information of the vehicle-mounted positioning device is bound to the vehicle identification.

[0064] When the vehicle approaches the parking lot area, the on-board positioning device will be activated to obtain the current location of the vehicle. When the vehicle is detected to have arrived at the parking lot entrance, the vehicle arrival time and vehicle identification will be sent as the third monitoring data to the data processing module through the communication module for data processing and analysis.

[0065] Furthermore, before executing the operation of determining and recording the time when the target vehicle enters the parking lot based on the first monitoring data, it also includes judging the number of vehicles entering the parking lot entrance within a second preset time range before and after the estimated time of arriving at the parking lot entrance in the first reservation data determined according to the first monitoring data; when the number of vehicles is more than one, the time when the target vehicle enters the parking lot is determined based on the vehicle identification in the first reservation data and the third monitoring data.

[0066] Furthermore, after the target parking space is occupied by the target vehicle, the second monitoring data further includes data indicating that the state of the target parking space changes from occupied to free as monitored by the geomagnetic monitoring module when the target vehicle leaves the target parking space.

[0067] The updating unit of the vehicle service module is further used to update the parking space status of the parking lot according to the data that the target parking space status changes from occupied to free.

[0068] Furthermore, the data processing module also includes a storage unit, which is used to store a table with the vehicle identification as an index based on the first reservation data and the second monitoring data.

[0069] The table includes the time when the vehicle corresponding to the vehicle identification enters the parking lot, the parking space information entered, the time when the vehicle enters the parking space, and the time when the vehicle leaves the parking space.

[0070] Furthermore, the vehicle service module also includes a parking fee payment unit, which is used to calculate the parking fee amount of the target vehicle based on the parking lot parking fee billing rules and the table data corresponding to the target vehicle, and allows the user to complete the parking fee payment operation based on the parking fee amount.

[0071] Preferably, the embodiment of the present invention calculates the driving route from the parking lot entrance to the reserved parking space by using the Dijkstra algorithm, specifically including:

[0072] First, the path of the parking lot is modeled as a weighted directed graph G = (V, E), where V is the set of all nodes, each node represents a location in the parking lot, such as the parking lot entrance, parking space, and intersection; E is the set of edges between nodes, each edge represents a channel between two locations; let e ij ∈E,e ij is the i-th position v i and the jth position v j The channel between each edge e ij Assign a non-negative weight w ij Indicates position v i and v j The travel time or distance between them.

[0073] Assume that the parking lot entrance node is s and the reserved target parking space node is t. The calculation goal of the Di jkstra algorithm is to find the shortest path from the parking lot entrance node s to the target parking space node t so that the total weight on the path is minimized.

[0074] The calculation process includes:

[0075] Define the distance array d[v] to represent the shortest distance from the starting node s to the node v. Initially:

[0076]

[0077] Define another priority queue Q to store the nodes to be visited, and initially add (s, 0) to the queue.

[0078] Each time, take out the node u with the shortest current distance from the priority queue and remove it from the queue. Traverse all nodes v connected to node u and update their shortest distances:

[0079] d[v]=min(d[v],d[u]+w uv )

[0080] Among them, d[u] represents the shortest known distance from node s to an intermediate node u, and w uv Represents the weight of the edge from node u to node v.

[0081] If the distance is updated, add the node v and the new distance to the priority queue. When the target parking space node t is visited, the algorithm ends. Set the predecessor array prev[v] to store the predecessor node of each node, and restore the shortest path from the parking lot entrance node s to the target parking space node t by backtracking the predecessor node.

[0082] Furthermore, when multiple navigation routes in a parking lot overlap in the same time period, traffic congestion may occur. Preferably, traffic load data is added during route planning to ensure that a smoother route is provided to the user.

[0083] Specifically, set it to each edge e ij Add the current load factor f ij (t), where t represents the current time. Then, the new edge weight is:

[0084] w′ ij =w ij ×(1+f ij (t))

[0085] Among them, f ij (t) represents edge e ij The traffic load at time t ranges from [0,1].

[0086] At each iteration, the real-time load of each edge is calculated:

[0087] d[v]=min(d[v],d[u]+w uv ×(1+f uv (t)))

[0088] Among them, f uv (t) represents the traffic load on the path from node u to node v at the current time t.

[0089] Through the above operations, the user's path planning is combined with the path data of other vehicles to avoid high-load areas as much as possible during navigation.

[0090] Furthermore, setting the load factor f uv (t) Calculated by combining real-time traffic flow data and average traffic flow data from historical time periods:

[0091]

[0092] Among them, N current N represents the number of vehicles on the path from node u to node v at the current time; avg N represents the historical average number of vehicles on the route in the same time period; max It represents the maximum vehicle carrying capacity on the path; α is the smoothing coefficient, which is used to adjust the weight between real-time data and historical data.

[0093] In the embodiment of the present invention, the above operation can calculate a route that allows the user to drive from the parking lot entrance to the reserved parking space more smoothly, thereby reducing the user's driving time in the parking lot and reducing the probability of congestion of vehicles in the parking lot.

[0094] Finally, it should be noted that the parking space monitoring system combining radar and geomagnetic technology disclosed in the embodiment of the present invention is only a preferred embodiment of the present invention, which is only used to illustrate the technical solution of the present invention, rather than to limit it.
