Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent parking, and in particular relates to an intelligent parking management system and method based on the Internet of Things. Background Art

[0002] With the increasing popularity of automobiles, parking lots are increasingly common in residential areas and large shopping malls. For example, underground parking garages are often complex or large in size. Upon entering a parking garage, drivers often have little idea of the parking space usage and distribution. To find an available or suitable parking space, drivers often have to drive while navigating the signs, searching blindly for a spot. A slight inattention can lead to missing important signs, making it difficult to quickly find a vacant space when parking is tight, causing significant inconvenience and making the search difficult and time-consuming.

[0003] In the existing technology, in order to solve the problems of "difficulty in finding a car" and "difficulty in finding the way", parking garages are usually equipped with intelligent car-finding terminals. The invention patent with application number CN201510364086.0 proposes a device that uses a mobile camera car to identify parking license plates, which can be used in the field of reverse car search. The license plates of vehicles parked in the parking spaces in the area are identified by a mobile camera car that stores its own location information. Since the parking system has entered the owner's identity information when the owner enters the parking lot, the parking space location information can be associated with the owner. When looking for a car, the owner can obtain a guidance path through mobile navigation technology. This method is highly intelligent and can be used both indoors and outdoors, but the implementation cost is relatively high.

[0004] Chinese invention patent application number 201310431360.2 discloses a reverse vehicle locating system and method in underground spaces based on fuzzy recognition technology. This system uses a vehicle RFID reader installed near a parking space to identify the vehicle owner and then associate the parking space location with the vehicle owner. This method offers high accuracy and is applicable both indoors and outdoors, but it is relatively expensive.

[0005] Chinese invention patent application number 201310484697.X proposes a method for reverse parking in an intelligent parking lot. While parking, the driver uses their mobile device to scan a QR code on each parking space. The mobile device then downloads an XML file and records the driver's parking location in the parking lot. When the driver returns to retrieve their vehicle, they scan the QR code anywhere in the parking lot with their mobile device to obtain a route from the scanned QR code location to the driver's parking space. This method is complex and lacks accuracy.

[0006] The above-mentioned solutions involve scanning QR codes on the roadside while walking with a smartphone to obtain parking locations, or querying parking locations through vehicle query machines installed at fixed points. These solutions have a low level of intelligence and do not provide localized real-time guidance. For large parking lots, the query information obtained is only displayed locally and cannot provide guidance along the way. It is difficult for users to directly reach the target location based on the query information obtained.

[0007] In addition, most of the current smart parking lots have implemented parking access control management, counting and displaying the number of empty parking spaces, and even realized parking space reservation and navigation to the parking lot. However, in the intelligent allocation of parking spaces and parking guidance, due to the weak GPS positioning signal in the parking lot and the lack of effective planning, design and information collection of parking space information, even after entering the parking lot, when users are looking for parking spaces, due to the lack of effective guidance, they always go around in circles in the parking lot, which inevitably causes problems such as meeting other vehicles and difficulty in parking, which in turn causes congestion in the parking lot, wasting a lot of time and thus affecting the utilization rate of the parking lot.

[0008] In addition, driverless cars will carry humans on smart highways, taking people to travel between streets and cities. Driverless cars will operate safely under the big data computing platform of the city's all-round intelligent traffic information network and the parallel computing and processing functions of the car's main control system. At present, parking lots have not conducted relevant research on the parking problem of driverless cars. How to seamlessly connect driverless cars and the management system of smart parking lots, so that the parking lot system automatically manages parking spaces and entry, parking and exit do not require human intervention to effectively save time and improve safety is an issue that needs further research and resolution. Summary of the Invention

[0009] To solve the above problems, the purpose of the present invention is to provide an intelligent parking management system and method based on the Internet of Things, which improves the accuracy of path guidance, saves user time, improves traffic safety, and optimizes the operational safety of garages in an environment with unmanned vehicles through the Internet of Things.

[0010] An intelligent parking management method based on the Internet of Things includes the following steps:

[0011] Step S1: When entering the basement, the user scans the QR code using the terminal to access the server through the terminal;

[0012] Step S2, the server sends an information sheet to the user terminal;

[0013] Step S3: The server automatically allocates a parking space according to the user option button on the information sheet, and sends a first navigation path from the user's current location to the allocated parking space and a second navigation path from the allocated parking space to the elevator to the user terminal.

[0014] Optionally, in step S2, the information sheet is a software interface.

[0015] Optionally, the information sheet includes a first area and a second area.

[0016] Optionally, the first area includes: dining, shopping, leisure, office and temporary parking option buttons; the second area includes: driverless car and manned car option buttons.

[0017] Optionally, in step S3, the second navigation path indicates that the allocated parking space is on the “left side” or “right side” of the elevator.

[0018] Optionally, in step S301, the underground garage is divided into zones: the garage area within a first distance range from the elevator is divided into zone I; the garage area between the first and second distances from the elevator is divided into zone II; and the garage area at a distance greater than the second distance from the elevator is divided into zone III.

[0019] Optionally, in step S302 , when the user selects a driverless car, if the parking space utilization rate of the entire garage is lower than a first threshold, the server allocates the parking space to zone II;

[0020] The length direction of the parking space allocated by the server is not parallel to the extension direction of the road facing the elevator door.

[0021] Optionally, in step S303, when the user selects a driven car, when the user selects dining in the first area of the information sheet, and when the parking space utilization rate in zone I is lower than a second threshold, the server allocates the parking space to zone I;

[0022] When the parking space utilization rate in zone I is greater than or equal to the second threshold and less than the third threshold, and the proportion of selected catering items in the parking spaces in zone I is lower than the first proportion, the server allocates the parking spaces to zone I; when the proportion of selected catering items in the parking spaces in zone I is greater than or equal to the first proportion and less than the second proportion, the server allocates the parking spaces to zone II; when the proportion of selected catering items in the parking spaces in zone I is greater than or equal to the second proportion, the server allocates the parking spaces to zone III;

[0023] When the parking space utilization rate in zone I is greater than a third threshold, the server allocates the parking space to zone II.

[0024] Optionally, when the user selects shopping in the first area of the information sheet, and when the parking space utilization rate in zone I is lower than a third threshold, the server allocates the parking space to zone I;

[0025] When the parking space utilization rate in zone I is greater than or equal to a third threshold, and the proportion of shopping items selected in the parking spaces in zone I is lower than a third ratio, the server allocates the parking spaces to zone I; when the proportion of shopping items selected in the parking spaces in zone I is greater than or equal to the third ratio, the server allocates the parking spaces to zone II;

[0026] When the user selects "Office" in the first area of the information sheet, and the parking space utilization rate of Area II is less than the fourth threshold, the server allocates the parking space to Area II; when the parking space utilization rate of Area II is greater than or equal to the fourth threshold, the server allocates the parking space to Area III;

[0027] When the user selects leisure or temporary parking in the first area of the information sheet, the server will allocate the parking space to Area III, and then to Area II after Area III is full.

[0028] The invention discloses an intelligent parking management system based on the Internet of Things, comprising a terminal and a server, wherein the terminal is connected to the server via the Internet of Things.

[0029] Beneficial technical effects:

[0030] The second navigation path indicates whether the assigned parking space is on the "left" or "right" side of the elevator. This allows users to easily determine whether to go to the left or right side of the elevator when they pick up their car. This improves navigation accuracy, saves time, and enhances user experience.

[0031] The length direction of the parking space allocated by the server is not parallel to the extension direction of the road directly opposite the elevator door, so as to avoid the situation where the self-driving car loses control or other situations and the self-driving car is driving on the road directly opposite the elevator door, causing traffic safety problems to other pedestrians going to and from the elevator.

[0032] By not allocating parking spaces for driverless cars to Zone I, the safety of pedestrians near the elevator door is guaranteed. The flow of people at the entrances and exits of elevator doors in Zones II or III is more dispersed and smaller than that in Zone I, thereby increasing the safety of driverless cars.

[0033] By allocating users with dining or shopping needs in different parking areas and near elevators, we can avoid a large number of dining users from driving in or out of Zone I near the elevator door. On the one hand, this avoids excessive congestion, on the other hand, it improves the personal safety of users, on the third hand, it reduces the risk of vehicle collisions and improves traffic safety, and on the fourth hand, it reduces the time it takes for users with dining or shopping needs to get to the elevator, thereby optimizing garage operations.

[0040] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] It should be noted that, in this document, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or apparatus comprising the element. Example

[0042] like Figure 1As shown, the underground garage parking space layout diagram includes an elevator 100, multiple parking spaces, and a circular road. First, current smart parking lots lack effective planning, design, and information collection for parking space information. After entering the underground garage, users often circle around in the parking lot to find a parking space near elevator 100 due to a lack of effective guidance, which inevitably leads to difficulties in meeting and parking. Second, due to the large size of the underground garage, users sometimes lose their bearings after exiting elevator 100, resulting in multiple round trips back and forth in the garage to find their parking space, increasing their time and inconvenience. Third, if a large number of short-term parking vehicles are parked near elevator 100, a large number of users will pass by, increasing user safety risks. Fourth, if the vehicle in need of parking is a self-driving car, there is currently no solution for how to arrange parking spaces for it.

[0043] An intelligent parking management method based on the Internet of Things includes the following steps:

[0044] Optionally, in this embodiment, the above method can be applied to Figure 2 In the hardware environment shown, which consists of a terminal 1 and a server 2, the terminal 1 is connected to the server 2 via a network. The server can be used to provide services to the terminal or a client installed on the terminal, optionally including game services or application services. A database can be set up on the server or independently of the server to provide data storage services for the server 2.

[0045] The aforementioned network may include, but is not limited to, at least one of the following: a wired network or a wireless network. The aforementioned wired network may include, but is not limited to, at least one of the following: a wide area network, a metropolitan area network, a local area network, or the Internet of Things. The aforementioned wireless network may include, but is not limited to, at least one of the following: Wi-Fi (Wireless Fidelity) or Bluetooth. Terminal 1 may be, but is not limited to, a mobile phone, a PC, or a tablet computer.

[0046] The method of the embodiment of the present application can be executed by the server 2, or by the terminal 1, or by both the terminal 1 and the server 2. The method of the embodiment of the present application can be executed by the user through the terminal 1 or by the client installed thereon.

[0047] In step S1, when entering the basement, the user uses the terminal to scan the QR code to access the server through the terminal.

[0048] An application can be run on the user's terminal device (which can be a mobile phone) to provide parking space search and allocation. The application can be installed on the terminal device or can be used without downloading and installing, such as a mini-program.

[0049] Step S2: The server sends an information sheet to the user terminal.

[0050] It can be understood that the information sheet is a software interface.

[0051] The information sheet includes a first area and a second area.

[0052] The first area includes: dining, shopping, leisure, office and temporary parking option buttons.

[0053] The second area includes: driverless car and manned car option buttons.

[0054] Step S3: The server automatically allocates a parking space according to the user option button on the information sheet, and sends a first navigation path from the user's current location to the allocated parking space and a second navigation path from the allocated parking space to the elevator to the user terminal.

[0055] Optionally, the second navigation path indicates whether the assigned parking space is on the "left" or "right" side of the elevator. This allows the user to easily determine whether to go to the left or right side of the elevator when picking up the car and exiting the elevator. This improves navigation accuracy, saves user time, and enhances user experience.

[0056] At the same time, the first navigation path from the user's current location to the allocated parking space and the second navigation path from the allocated parking space to the elevator are sent to the user terminal, so that the user can interact with the information of parking and picking up the car at one time, thereby improving the interaction efficiency. Optionally, the first navigation path and the second navigation path include both a dynamic navigable map and a static planar position map from the user's current location to the allocated parking space and a static planar position map from the allocated parking space to the elevator.

[0057] The automatic allocation of parking spaces is specifically as follows:

[0058] Step S301, partition the underground garage, divide the garage area within the first distance range from the elevator into Zone I, divide the garage area between the first distance and the second distance from the elevator into Zone II, and divide the garage area at a distance greater than the second distance from the elevator into Zone III.

[0059] Optionally, the second distance is greater than the first distance.

[0060] Optionally, the first distance is set to 20-100 meters.

[0061] Optionally, the second distance is set to 120-200 meters.

[0062] In step S302 , when the user selects an unmanned vehicle, if the parking space utilization rate of the entire garage is lower than a first threshold, the server allocates the parking space to zone II.

[0063] Optionally, the length direction of the parking space allocated by the server is not parallel to the extension direction of the road facing the elevator door, so as to avoid the situation where the driverless car loses control or other situations occur and the driverless car travels on the road facing the elevator door, causing traffic safety problems to other pedestrians going to and from the elevator.

[0064] Understandably, the length of a parking space is greater than its width.

[0065] It can be understood that the road that the elevator door faces can be a road connected to the elevator door.

[0066] Optionally, the first threshold is 10%-20%.

[0067] If the parking space utilization rate of the entire garage is greater than or equal to the first threshold, the server allocates the parking space to zone III.

[0068] By not allocating parking spaces for driverless cars to Zone I, the safety of pedestrians near the elevator door is guaranteed. The flow of people at the entrances and exits of elevator doors in Zones II or III is more dispersed and smaller than that in Zone I, thereby increasing the safety of driverless cars.

[0069] Step S303: When the user selects a driven car, when the user selects dining in the first area of the information sheet, and when the parking space utilization rate in area I is lower than a second threshold, the server allocates a parking space to area I;

[0070] When the parking space utilization rate in zone I is greater than or equal to the second threshold and less than the third threshold, and the proportion of selected catering items in the parking spaces in zone I is lower than the first proportion, the server allocates the parking spaces to zone I; when the proportion of selected catering items in the parking spaces in zone I is greater than or equal to the first proportion and less than the second proportion, the server allocates the parking spaces to zone II; when the proportion of selected catering items in the parking spaces in zone I is greater than or equal to the second proportion, the server allocates the parking spaces to zone III;

[0071] When the parking space utilization rate in zone I is greater than a third threshold, the server allocates the parking space to zone II;

[0072] Preferably, the second threshold is smaller than the third threshold.

[0073] Preferably, the second threshold is 10%-20%, and the third threshold is 25%-40%.

[0074] Preferably, the third threshold is twice the second threshold.

[0075] Preferably, the first ratio is smaller than the second ratio.

[0076] Preferably, the first ratio is 15%-25%, and the second ratio is 30%-50%.

[0077] By allocating users with catering needs in different parking areas, we can avoid a large number of catering users from concentratedly entering or exiting Zone I near the elevator door. On the one hand, this avoids excessive congestion, on the other hand, improves the personal safety of users, and thirdly, reduces the risk of vehicle collisions and improves traffic safety.

[0078] When the user selects shopping in the first area of the information sheet, and the parking space utilization rate in zone I is lower than a third threshold, the server allocates the parking space to zone I;

[0079] When the parking space utilization rate in zone I is greater than or equal to a third threshold, and the proportion of shopping items selected in the parking spaces in zone I is lower than a third ratio, the server allocates the parking spaces to zone I; when the proportion of shopping items selected in the parking spaces in zone I is greater than or equal to the third ratio, the server allocates the parking spaces to zone II;

[0080] Preferably, the third ratio is 45%-65%.

[0081] Since shopping time is generally shorter than dining time, and the distance between shopping items and the car in the parking space is too far, it will add more weight to the user, so in order to improve the user experience and save the time of users with shopping needs, more users with shopping needs are arranged in Zone I, which is closer to the elevator. In addition, the turnover rate of parking spaces in Zone I near the elevator is improved, and the utilization rate of parking spaces is increased.

[0082] When the user selects office in the first area of the information sheet, when the parking space utilization rate in Zone II is less than the fourth threshold, the server allocates the parking space to Zone II; when the parking space utilization rate in Zone II is greater than or equal to the fourth threshold, the server allocates the parking space to Zone III.

[0083] By allocating users of office options to Zone II or Zone III, the experience of users with dining and shopping needs is improved, and the economic benefits of the garage are increased.

[0084] Preferably, the fourth threshold is 30%.

[0085] When the user selects leisure or temporary parking in the first area of the information sheet, the server will allocate the parking space to Area III, and then to Area II after Area III is full.

[0086] Optionally, if the server does not receive the information sheet within the set time, the server allocates parking spaces according to the temporary parking and manned car options.

[0087] Optionally, a lock may be provided for each parking space. When the server allocates a parking space, the server controls the lock of the parking space to be in an open state, allowing the user to drive into the parking space; when the server does not allocate a parking space, the server controls the lock of the parking space to be in a closed state, preventing the user from driving into the parking space.

[0088] Optionally, the server controls the vehicle lock and obtains the vehicle lock status through the Internet of Things.

[0089] The server can also provide the following functions to car owners or users through the mobile app:

[0090] Parking space marking: Car owners or users can check the parking space, parking time, and fees incurred through their mobile phones;

[0091] Reservation parking: Car owners or users can reserve parking for a certain time period. Parking spaces in a certain area of the basement can be designated as reservable spaces.

[0092] Vehicle Pickup Guide: The car owner or user can select the elevator entrance to the basement and the location where the vehicle is parked. The basement online plan can generate a route for the user to find the vehicle. These routes can be pre-generated.

[0093] Timeout reminder: remind the car owner or user ten minutes before the free parking time or reserved parking time is exceeded.

[0094] An intelligent parking management system based on the Internet of Things includes a terminal and a server. The terminal is connected to the server via a network. The server can be used to provide services for the terminal or a client installed on the terminal. The service can optionally be a game service or an application service. A database can be set up on the server or independently of the server to provide data storage services for the server.

[0095] Preferably, the network is the Internet of Things.
