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.

In addition, the location-based vehicle parking navigation system according to the present invention is processed using a GPS, in which case the GPS system to communicate with the vehicle location tracking system 200 and the mobile parking location guidance system 400 Is built.

In addition, in terms of the functional aspects of each sub-system, the integrated parking lot information management system 100 is a system that serves as a main server of the entire location-based vehicle parking navigation system, while managing the parking lot information of the whole country. Receives a request message from the Internet-linked navigation system installed in each vehicle, analyzes it, and returns necessary information.

That is, a general road navigation program is executed in a terminal mounted on a vehicle, and when the vehicle arrives at the parking area, the parking guidance program of the present invention is activated and executed, and transmits the current location information to the server through the wireless Internet. The parking guide information is downloaded from the server, and the parking guide information such as a map, a parking space, a recommended parking area, and an optimal driving route is performed.

In this case, the navigation terminal mounted on the vehicle recognizes the parking zone (communication point with the server) pre-input on the program and automatically parks the parking guide program when the vehicle's location is within the corresponding parking zone. Guidance switching may be possible.

To this end, it includes an information retrieval and processing unit, interaction processing unit, integrated parking lot information management DB unit.

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. The vehicle must be immediately provided with a list of new available spaces, so it maintains not only information about the available spaces, but also any vehicle currently waiting in the parking lot.

In addition, when the parking available space information is changed, the changed space information is broadcast to vehicles currently waiting.

Since these database groups exist in logically and physically different conceptual spaces, synchronization and massive sharing / distribution of large data transactions are essential. In addition, since it uses web-based network communication, stable bandwidth of each regional database can be an important variable for the performance of the entire system.

In addition, the managers of each parking lot should register and manage the unique information of the parking lot (floor plan information, parking space information, internal distance information, entrance GPS value information, floor altitude information and slope information, etc.) through the local data group of the corresponding area. do.

In other words, as shown in FIG. 4, in the case of information dynamically changed due to parking and unloading of the vehicle, the application thereof does not require any management work by the administrator, and is integrated with the in-vehicle interlocking navigation system 300. It is made through the automated information transmission between the parking lot information management system 100, the integrated parking lot information management system 100, when requested from the navigation terminal of the individual user vehicles, accesses the local data group assigned to the area to query The process extracts the necessary information and transmits it to the navigation system of the user's vehicle. Since the query processing requested online from the managers of the individual parking lots is performed on the local data group for each region of the region, it distributes the traffic for the entire system. Will have an effect.

Meanwhile, the vehicle location tracking system 200 includes a vehicle location information receiver R and a vehicle location information processor P as shown in FIGS. 1 and 5, and the vehicle location information receiver R is GPS receiving module 210, sensor data receiving module 220, wireless AP information receiving module 230, the vehicle location information processing unit (P) is a location information integration module 240 and location information determination module 250 It is composed of

In this case, the wireless AP information receiving module 230 is an example, and represents a plurality of sensors for determining the location already installed in the parking lot.

Thus, the vehicle location tracking system 200 calculates the current location of the vehicle in real time and transmits it to the Internet-linked navigation system 300 through various sensor data including GPS satellite data inside the driver's vehicle. .

In this case, in the region where GPS satellite data is received, the position of the vehicle is basically determined by the information received by the GPS receiving module, and when the vehicle enters a GPS shadow area such as an underground parking lot and cannot receive the GPS information. The location of the vehicle is estimated and transmitted to the system using various types of sensors installed inside the vehicle.

To this end, the vehicle location tracking system 200 is responsible for receiving all information related to the vehicle location to receive GPS information, various sensor information in the vehicle, and wireless AP (Access Point) signal information to obtain integrated location information. A vehicle location information receiver R for transmitting to the vehicle location information processor P; It includes a vehicle location information processing unit (P) for determining the location of the vehicle by weighting the accuracy of the various sensors to take the function of determining the location of the actual vehicle by integrating the information transmitted from the vehicle location information receiver (R).

The vehicle location information receiver R includes a GPS receiving module 210, a sensor data receiving module 220, and a wireless AP information receiving module 230. The GPS receiving module 210 includes GSP coordinate information of a vehicle.

Only information request control is transmitted.

The parking lot map information is transmitted to the map profile management module 312 and the in-vehicle communication processor 330, and the available space information in the parking lot is transmitted to the optimal path search module 342 together with the map profile.

In addition, the vehicle receives the real-time location information of the vehicle in the parking lot from the parking lot until the parking is completed and transmits to the in-vehicle communication processing unit 330 so that the driver can check the vehicle location information up to the selected parking location in real time. When the parking of the vehicle is completed, the parking position information of the vehicle is received and transmitted to the map profile management module 312 and the wireless Internet communication unit 320.

In addition, the map profile management module 312 manages the parking lot map information and the preferred parking position information visited by the driver, stores individual parking lot map information and the final parking position, and is based on the cluster information performed in the data mining module. The driver's preferred parking location information is profiled and managed.

In addition, the wireless Internet communication unit 320 is a processing unit that transmits and receives all the necessary information and control information of the integrated parking lot information management system 100 to the information request control module 314 and the spatial information display module 338, information The transmitting module 322 transmits the request information necessary for controlling the Internet-linked navigation system 300 and the location information acquired from the navigation system to the integrated parking lot information management system 100, and the parking lot of the vehicle from the vehicle location tracking system 200. When the access information is delivered and received by the parking lot information processing unit 310, the driver requests the integrated parking lot information management system 100, which is the main server, for map information about the parking lot to be entered in the future and available parking space information in the parking lot.

In addition, when the user finally completes parking by using the information received from the main server, the vehicle location tracking system 200 receives the current parking position of the vehicle and transmits it to the integrated parking lot information management system 100. At the same time, a user mobile service is requested.

In addition, the information receiving module 324 receives the information requested by the integrated parking lot information management system 100, which is the main server, and transmits necessary information to each module inside the Internet-linked navigation system 300, and the integrated parking lot information management system ( When receiving the parking lot map information and the available space information from the 100, and transmits two pieces of information to the information request control module 314 for system control, and transmits the available space information to the individual module of the vehicle communication processing unit 330 The user is guided to select a desired parking location.

Further, the in-vehicle communication processor 330 is a processor that displays all services provided by the integrated system for location-based parking guidance and parking lot management and receives input from the driver. The map display module 334 allows the driver to enter. An application module for displaying detailed map information of a parking lot to be operated, and is operated by receiving map information of the corresponding parking lot from the information request control module 314 at the time when the driver enters the parking lot.

In addition, the space information display module 338 is a module for displaying space information available for parking in a parking lot. The space information display module 338 provides the parking space information received from the wireless Internet communication unit 320 to the driver in real time until the parking is completed. Input module 332 is the only module that the Internet-linked navigation system 300 receives the input of the driver as the driver to check the map of the parking lot and the available space information displayed on the navigation terminal screen and to select the desired location In addition to providing an intuitive function, the movement route display module 336 has a function of displaying the movement route to the parking position selected by the driver, and requests the information from the optimal route search module 342 to the destination parking position. Receives the position of the vehicle from the control module 314 and moves between these two points Is a display in real time the current position in the vehicle.

In addition, it receives the coordinates that can change the direction of the parking lot and direction information from each coordinate, and creates a directional graph based on this information, and finds the shortest path by adding a certain cost to the direction change on the derived graph. Done.

Accordingly, dozens or less of turning point (node) information is used per parking space, and data transmission and reception are easy and error rate is reduced. In addition, since the driver of the vehicle pursues the convenience of driving rather than the efficiency obtained at the shortest distance, the driver can recommend the route that can reach the destination with the minimum direction by weighting the cost when the direction is changed. The same applies to the optimum path search module 430 of the guide system 400.
