INTEGRATED SYSTEM FOR PARKING GUIDANCE AND PARKING LOT MANAGEMENT}

The present invention relates to an integrated system for parking guidance and parking lot management. More specifically, the existing GPS-based navigation system can be extended by only an integrated parking lot information management system which is a main server and a terminal including a subsystem mounted in a vehicle. It is possible to manage the parking lot that does not reach, and it is related to an integrated system for improved parking guidance and parking lot management to build a national parking management system that is controlled under one main server management instead of an individual parking management system.

In general, large buildings, large department stores, shopping centers, large discount stores, and public institutions have increased the number of people using cars to park their vehicles in the multi-storey car parks in the basement. Although managed, but mainly toll collection, many parking personnel are mobilized to guide each floor.

In addition, a parking guide system for providing parking guide information automatically by installing a vehicle detector for each parking area is known, but this is merely a guide for the number of parking spaces for each floor of the parking lot, and a guide for a specific parking space. The driver is often looking for a parking space because it can not provide a lot of time and effort to secure a parking space, and the waste of manpower due to the placement of parking personnel is also severe.

In addition, urban parking spaces are becoming increasingly integrated and large-scaled, and some large parking buildings only provide information on the number of cars that can be parked and cannot accurately identify and provide accurate parking spaces and their locations in real time.

In addition, the underground parking lot provided in the underground space was unable to determine the location, so it was not possible to obtain information related to the parking lot using only GPS.

Recently, the concept of U-Parking service that can provide various convenience functions such as automatic recognition of vehicle, settlement of parking fee, analysis of occupancy status of parking surface based on video recognition technology, sensor recognition technology, network technology, etc. This is emerging.

For example, as a technology related to parking-only management using image information, Published Patent No. 2009-0020533 (2009.02.26) developed by Kyungpook National University Industry-Academic Cooperation Foundation, developed by "Parking Management System and Method", Nexpa System Co., Ltd. Registered Patent No. 0444478 (2008.07.01) "Parking Lot Management System and Management Method", Registered Patent No. 0830844 (2008.05.14) "Parking Management System Using Camera" developed by Korea Dynamics Co., Ltd. have.

Another example is a technology related to parking-only management using a driver's mobile device. For example, Korean Patent Application Publication No. 2007-0076009 (2007.07.24) developed by Pantech Co., Ltd. "a mobile communication terminal equipped with a smart card. Used parking management method and system.

Another example is a technology related to parking management using sensor data, for example, Patent Registration No. 0909436 (2009.07.20) developed by S & R Co., Ltd. "Parking management system, sensor node and its parking management method" , Publication No. 2009-0035378 (2009.04.09) developed by KT Co., Ltd. "U-City intelligent system and method", Publication No. 2008-0026282 (2008.03.25) developed by SK Telecom Co., Ltd. " Parking management system and method using RFID ", and" parking management system "for the registered room No. 0306714 (2003.02.26) developed by Qfield.

It will guide you to come back easily.

In addition, if the mobile terminal is equipped with a means for acquiring real-time location information, such as GPS, it may perform a real-time navigation function to the parked vehicle.

In this case, the mobile parking location guide system 400 may be selectively configured, and thus, of course, the associated configurations with other sub-systems linked thereto may be selectively configured.

Thus, the present invention transmits the vehicle position information that is calculated / obtained in real time through the GPS and various sensor data to the Internet-linked navigation system 300, the Internet-linked navigation system 300 through this information to determine the current situation When the vehicle enters a specific parking lot through the current situation analysis, the information request control module of the Internet-linked navigation system 300 checks whether the floor plan of the parking lot is owned, and then the integrated parking lot information management system through the wireless Internet communication unit. After requesting the necessary information to the 100), the integrated parking lot information management system 100 receives the requested information from the integrated parking information DB, and then sends back the necessary information through the navigation service provider, after the parking is normally Internet-linked navigation system 300 is the vehicle location information and mobile service request menu The message is delivered to the integrated parking lot information management system 100, and the integrated parking lot information management system 100 receiving the data updates the integrated parking information DB, and then changes the floor plan and the parking location of the parking lot to the user's mobile terminal through the mobile service provider. It can be utilized in the form of transmitting.

To implement this, the integrated parking lot information management system 100, as shown in Figure 2, the parking lot and vehicle information entered by the vehicle from the wireless Internet communication unit 320 of the Internet-linked navigation system 300 built in the vehicle It is responsible for the main server system's ability to receive and retrieve relevant current information.

In addition, from the moment the driver's vehicle enters a specific parking lot, the driver also searches for and delivers the available parking spaces and the parking plan plan image to the driver. For this purpose, the interaction processor 110, the information search and the processor 120, the integrated parking lot management DB 130.

In this case, the interaction processor 110 is a part that processes direct information transmission and reception with the Internet-based navigation system and the driver's mobile device mounted on the driver's vehicle.

In addition, the information retrieval and processing unit 120 is a part for quickly searching and extracting an empty parking space that can be parked in a corresponding parking lot requested by a vehicle and profiling an individual preferred space for each driver.

In this case, the empty parking space can be checked by the information retrieval and processing unit 120 based on whether the parking space is occupied as described above under the conditions of using the same system of the present invention. The management system or the controller and the integrated parking lot information management system 100 may be configured to communicate with each other so as to be guided by updating the integrated parking lot management DB 130.

In addition, the integrated parking lot management DB 130 is a part that registers / deletes / manages a plurality of parking lot data and processes a query for the location information of available parking spaces changing in real time and provides them to the interaction processor.

In particular, the interaction processing unit 110 is responsible for direct data communication with the in-vehicle interlocking navigation system 300 and the driver's mobile device, for example, a map message of the parking lot, a request message for the current available parking space information, and the present. It receives the location information of the vehicle and delivers the result of the requested query in conjunction with the information retrieval and processing unit 120 and the integrated parking lot management DB (130).

In this case, the interaction processing unit 110 is a request information receiving module 112 for receiving a query from the Internet-linked navigation system 300, a navigation service provider 114 for transmitting a response result of the query to the in-vehicle system And a mobile service provider 116 for delivering the response result to the driver's mobile device.

At this time, the request information receiving module 112 receives the request information and location information transmitted from the Internet interlocking navigation system 300 to deliver to the search / extraction module 122 constituting the information search and processing unit 120 As the first vehicle enters the parking lot, the map information request message of the parking lot and the available space information request message of the parking lot are received, and after parking ends, the location information of the parked vehicle and the mobile service request message are received. The receiving module receives the information and delivers the information to the search / extraction module 122 to perform a query from the database.

The navigation service provider 114 transmits data to the Internet-linked navigation system 300 during the interaction process, and transfers the parking lot map retrieved from the integrated database and the currently available parking space information. Receiving and transmitting the information to the information receiving module 324 (see FIG. 6) of the wireless internet communication unit 320 (see FIG. 1) implemented in the Internet-linked navigation system 300 according to the defined protocol. .

In addition, the mobile service provider (Mobile Service Provider) 116 is a module for transmitting data to the driver's personal mobile device, the driver's phone number registered in the integrated parking lot management DB 130 and the corresponding parking lot information In this case, the vehicle location of the driver is searched in the parking lot and the parking map and the vehicle position coordinate information are transmitted to the driver's mobile terminal, which is similar to the navigation service provider 114 and transfers necessary information to the mobile device. Since the service is supported, the mobile service provider 116 will be defined.

Meanwhile, the information retrieval and processing unit 120 serves to retrieve the information of the parking lot from the integrated parking lot management DB 130 in response to the parking lot map and the available space information request message, and inform the interaction processing unit 110 of the result. In addition, the processing unit is configured to reflect user characteristics by mining the preferred space for each driver by clustering the space information at the end of parking.

The information retrieval and processing unit 120 includes a data retrieval / extraction module 122 and a data mining module 124, as shown in FIG.

In this case, the data retrieval / extraction module 122 retrieves the parking lot information from the integrated parking lot management DB 130 when the parking lot map and the available space information request message are transmitted from the interaction processing unit 110, and retrieves the result of the interaction processing unit ( 110, and the integrated parking lot management DB (130) must be implemented to enable rapid information retrieval and extraction because the integrated parking management DB (130) has to manage in real time the current state of multiple parking lots and many parking spaces existing for each parking lot. .

In addition, the data mining module 124 performs a data stream clustering algorithm, which is one of data mining techniques, based on spatial information on which the driver frequently completes parking, to perform user-specific spatial profiling in real time. In addition, this module processes two-dimensional or three-dimensional spatial coordinate data generated by each driver and transmits them as one data transaction through a grid-based clustering technique of dynamic structure for data transaction processing.

For example, as shown in FIG. 3, each data transaction is divided into grid cells of a corresponding range, and adjacent data objects are determined as a cluster based on statistics on their frequency and distribution, and periodically or forcibly depending on available memory space. The data may be mined by adjusting the size of the grid cells by searching all grid cells and performing a pruning process on the grid cells below the battery map.

On the other hand, the integrated parking lot management DB 130 is a large-capacity database system that stores and manages the parking lots for each area to be managed, space information for each parking lot, current parking space, and information on vehicles in the current parking lot.

Thus, in order to quickly process the queries requested by the data retrieval / extraction module 122, the database includes a regional parking lot map DB 132, a real-time parking lot available space management DB 134, and real-time waiting vehicle information, as shown in FIG. DB 136 is included, and each database group has different data update and query request cycles, so that individual indexing and database integration management techniques are applied to minimize the time required for accessing these databases.

In this case, the parking lot map DB 132 for each region may register and delete the target parking lots for each region, and store a parking area map of the parking lots and the total number of available parking lots.

And, when the vehicle enters the parking lot, it provides a map image of the parking lot, and the frequency of access is very small compared to other database groups and is semantically higher.

In addition, the real-time parking lot available space management DB 134 is a database that is used to search for the space available for parking in each parking area, the search process is performed once as the vehicle enters the parking lot and the result is transmitted along with the parking map. The retrieved available space results are transferred to the navigation service provider 114 of the interaction processor 110 and displayed on the in-vehicle navigation terminal.

In addition, the real-time standby vehicle information DB 136 is a database that stores information of various vehicles that are not currently parked, that is, parked, in a parking lot.
