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 popularity of cars, parking lots are set up in both residential and large shopping malls. For example, underground parking garages are inevitably complex in design or large in area. When people enter the underground garage, they cannot understand the use and distribution of parking spaces in the underground garage. If you want to find an empty or suitable parking space, you can only drive while identifying the direction according to the on-site signs and look for parking spaces blindly. If you are not careful, you may miss important signs. When parking spaces are tight, you cannot quickly find an empty parking space, which brings great inconvenience. There are problems such as difficulty and time in finding an empty parking space.

[0003] In the prior art, in order to solve the problems of "difficulty in finding a car" and "difficulty in finding the way", intelligent car-finding terminals are usually installed in parking garages. The invention patent with application number CN201510364086.0 proposes a device for identifying parking license plates using a mobile camera car, which can be used in the field of reverse car search. The license plates of vehicles parked in parking spaces in the area are identified by a mobile camera car that stores its own location information. Since the parking lot system has entered the identity information of the owner when entering 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 has a high degree of intelligence and can be used both indoors and outdoors, but the implementation cost is relatively high.

[0004] The Chinese invention patent application number 201310431360.2 discloses a reverse vehicle search system and method in underground space based on fuzzy recognition technology, which uses a vehicle RFID reader installed next to the parking space to identify the owner's information, and then associates the parking space location information with the owner. This method has high accuracy and can also be applied indoors and outdoors, but the investment cost is relatively high.

[0005] The Chinese invention patent application number 201310484697.X proposes a method for reverse car search in an intelligent parking lot. When parking, the car owner uses a personal mobile terminal to scan the QR code on each parking space. The personal mobile terminal downloads an XML file and records the parking position of the car owner in the parking lot. When the car owner returns to pick up the car, the personal mobile terminal scans the QR code in any area of ​​the parking lot to obtain the route from the location where the QR code is scanned to the car owner's parking space. This method is complex to operate and has low accuracy.

[0006] The above-mentioned solutions use a smartphone to scan a QR code on the roadside while walking to obtain a parking location, or use a vehicle query machine set up at a fixed point to query the parking location. The degree of intelligence is low and local real-time guidance is not achieved. 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 terms of 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 looking for a parking space, due to the lack of effective guidance, users always go around in circles in the parking lot, which inevitably causes problems such as meeting other vehicles and parking difficulties, 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 roads, 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 main control system. Currently, parking lots have not conducted relevant research on the parking problem of driverless cars. How to seamlessly connect the management system of driverless cars and smart parking lots, so that the parking lot system automatically manages parking spaces and entry, parking and exit do not require human intervention at all, in order to effectively save time and improve safety is a problem 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 driverless cars through the Internet of Things.

[0010] An intelligent parking management method based on the Internet of Things comprises the following steps: Step S1, when entering the basement, the user uses the terminal to scan the QR code to access the server through the terminal; Step S2, the server sends an information sheet to the user terminal; 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.

[0011] Optionally, in step S2, the information sheet is a software interface.

[0012] Optionally, the information sheet includes a first area and a second area.

[0013] 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.

[0014] 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.

[0015] 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 distance and the second distance 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.

[0016] Optionally, in step S302, when the user selects the 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; 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.

[0017] 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 area I is lower than a second threshold, the server allocates the parking space to area I; When the parking space utilization rate of 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 used 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 used 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 used in zone I is greater than or equal to the second proportion, the server allocates the parking spaces to zone III; When the parking space utilization rate in zone I is greater than the third threshold, the server allocates the parking space to zone II.

[0018] Optionally, when the user selects shopping in the first area of ​​the information sheet, when the parking space utilization rate of zone I is lower than a third threshold, the server allocates the parking space to zone I; When the parking space utilization rate of zone I is greater than or equal to the third threshold, and the proportion of shopping items selected in the parking spaces used in zone I is lower than the third proportion, the server allocates the parking spaces to zone I; when the proportion of shopping items selected in the parking spaces used in zone I is greater than or equal to the third proportion, the server allocates the parking spaces to zone II; When the user selects office in the first area of ​​the information sheet, when 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; 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.

[0019] An intelligent parking management system based on the Internet of Things comprises a terminal and a server, wherein the terminal is connected to the server via the Internet of Things.

[0020] Beneficial technical effects: The second navigation path indicates whether the assigned parking space is on the "left side" or "right side" of the elevator. In this way, when the user gets the car and walks out of the elevator, he will not be confused about whether to walk to the left or right side of the elevator, which improves accuracy, saves user time, and improves user experience.

[0021] 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 runs on the road facing the elevator door, causing traffic safety problems to other pedestrians going to and from the elevator.

[0022] 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.

[0023] 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.

[0029] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with 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.

[0030] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element. Example

[0031] like Figure 1 As shown, the underground garage parking space layout diagram has an elevator 100, multiple parking spaces and a ring road. First, the current intelligent parking lot lacks effective planning, design and information collection of parking space information. After entering the underground garage, users are looking for parking spaces near the elevator 100. Due to the lack of effective guidance, they always go around in circles in the parking lot, which inevitably causes difficulties in meeting and parking. Second, since the underground garage is large, users sometimes cannot tell the direction after coming out of the elevator 100, resulting in multiple turns in the garage to find their own parking space, which increases the user's time cost and is inconvenient for the user's travel. Third, if a large number of short-term parking cars are parked near the elevator 100, a large number of users will pass by near the elevator 100, increasing the safety risk of users. Fourth, if the car that needs to be parked is an unmanned vehicle, there is currently no solution for how to arrange parking spaces for unmanned vehicles.

[0032] An intelligent parking management method based on the Internet of Things comprises the following steps: Optionally, in this embodiment, the above method can be applied to Figure 2 In the hardware environment shown, which is composed of a terminal 1 and a server 2, the terminal 1 is connected to the server 2 via a network, and the server can be used to provide services for the terminal or a client installed on the terminal, and the service can be optionally a game service or an application service. A database can be set on the server or independently of the server to provide data storage services for the server 2.

[0033] The above network may include but is not limited to at least one of the following: wired network, wireless network. The above wired network may include but is not limited to at least one of the following: wide area network, metropolitan area network, local area network, Internet of Things, and the above wireless network may include but is not limited to at least one of the following: WIFI (Wireless Fidelity) or Bluetooth. The terminal 1 may be but is not limited to a mobile phone, a PC or a tablet computer, etc.

[0034] 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 user can execute the method of the embodiment of the present application through the terminal 1, or the client installed thereon can execute it.

[0035] Step S1, when entering the basement, the user uses the terminal to scan the QR code to access the server through the terminal.

[0036] An application may be run on the user's terminal device (the terminal device may be a mobile phone), and the application may be used to provide parking space search and allocation. The application may be installed on the terminal device, or may be a program that can be used without downloading and installing, such as a mini program.

[0037] Step S2: the server sends an information sheet to the user terminal.

[0038] It can be understood that the information sheet is a software interface.

[0039] The information sheet includes a first area and a second area.

[0040] The first area includes: dining, shopping, leisure, office and temporary parking option buttons.

[0041] The second area includes: driverless car and manned car option buttons.

[0042] 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.

[0043] Optionally, the second navigation path indicates that the allocated parking space is on the "left side" or "right side" of the elevator. In this way, when the user gets the car and walks out of the elevator, he will not be confused about whether to walk to the left or right side of the elevator, which improves accuracy, saves user time, and improves user experience.

[0044] At the same time, a first navigation path from the user's current position to the allocated parking space and a second navigation path from the allocated parking space to the elevator are sent to the user terminal, so that the user's parking and picking up information can be interacted 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 plan position map from the user's current position to the allocated parking space and a static plan position map from the allocated parking space to the elevator.

[0045] The automatic allocation of parking spaces is specifically as follows: Step S301, zoning the underground garage, dividing the garage area within the first distance range from the elevator into Zone I, dividing the garage area between the first distance and the second distance from the elevator into Zone II, and dividing the garage area at a distance greater than the second distance from the elevator into Zone III.

[0046] Optionally, the second distance is greater than the first distance.

[0047] Optionally, the first distance is set to 20-100 meters.

[0048] Optionally, the second distance is set to 120-200 meters.

[0049] 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.

[0050] 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.

[0051] Understandably, the length of a parking space is greater than its width.

[0052] It can be understood that the road directly facing the elevator door can be a road connected to the elevator door.

[0053] Optionally, the first threshold is 10%-20%.

[0054] 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.

[0055] 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.

[0056] 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 of area I is lower than the second threshold, the server allocates the parking space to area I; When the parking space utilization rate of 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 used 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 used 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 used in zone I is greater than or equal to the second proportion, the server allocates the parking spaces to zone III; When the parking space utilization rate in zone I is greater than a third threshold, the server allocates the parking space to zone II; Preferably, the second threshold is smaller than the third threshold.

[0057] Preferably, the second threshold is 10%-20%, and the third threshold is 25%-40%.

[0058] Preferably, the third threshold is twice the second threshold.

[0059] Preferably, the first ratio is smaller than the second ratio.

[0060] Preferably, the first ratio is 15%-25%, and the second ratio is 30%-50%.

[0061] 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 on the third hand, reduces the risk of vehicle collisions and improves traffic safety.

[0062] When the user selects shopping in the first area of ​​the information sheet, and the parking space utilization rate in area I is lower than the third threshold, the server allocates the parking space to area I; When the parking space utilization rate of zone I is greater than or equal to the third threshold, and the proportion of shopping items selected in the parking spaces used in zone I is lower than the third proportion, the server allocates the parking spaces to zone I; when the proportion of shopping items selected in the parking spaces used in zone I is greater than or equal to the third proportion, the server allocates the parking spaces to zone II; Preferably, the third ratio is 45%-65%.

[0063] Since shopping time is generally shorter than dining time, and the distance from shopping to 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 increased, and the utilization rate of parking spaces is increased.

[0064] 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.

[0065] 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.

[0066] Preferably, the fourth threshold is 30%.

[0067] 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.

[0068] Optionally, if the server does not receive the information sheet within a set time, the server allocates parking spaces according to temporary parking and manned car options.

[0069] Optionally, a car lock may be set for each parking space. When the server allocates a parking space, the server controls the car lock of the parking space to be in an open state, and the user can drive the car into the parking space; when the server does not allocate a parking space, the server controls the car lock of the parking space to be in a closed state, and the user cannot drive the car into the parking space.

[0070] Optionally, the server controls the vehicle lock and obtains the vehicle lock status through the Internet of Things.

[0071] The server can also provide the following functions to car owners or users through the mobile app: Parking space marking: Car owners or users can check the parking space, parking time, and fees incurred through their mobile phones; Reservation parking: Car owners or users can make reservations to park their vehicles during a certain time period, and a certain area of ​​parking spaces in the basement can be divided as reservable parking spaces; 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. Timeout reminder: remind the car owner or user ten minutes before the free parking time or reserved parking time is exceeded.

[0072] An intelligent parking management system based on the Internet of Things includes a terminal and a server. The terminal is connected to the server through a network. The server can be used to provide services for the terminal or a client installed on the terminal. The service can be optionally a game service or an application service. A database can be set on the server or independently of the server to provide data storage services for the server.

[0073] Preferably, the network is the Internet of Things.
