Description

Real-time parking surface management and 3D visualization based parking management system and method using RFID and USS {Method for controlling parking lot with 3D display}

The present invention manages the parking surface in real time using Radio Frequency Identification (RFID) and Ubiquitous Sensor Network (USN), and provides real-time parking status to the driver, parking guidance, vehicle guidance, exit guidance, etc. It provides a parking management system and its method.

Recent trends in the RFID industry include the 900MHz band, Passive Type research, which is the most active and highly competitive field, and is used in various fields such as distribution, logistics, and asset management. Active RFID technology is a technology that is not yet common, and complements the limitations of passive RFID technology, and its utilization is rapidly increasing in various fields. Passive RFID technology recognizes the unique information stored in the RFID tag by sending radio waves from the router, whereas active RFID technology sends a radio wave directly from the RFID tag to the receiver. The recognition distance of the tag is limited in the range of 10Cm to 7m long, while active technology can extend the recognition distance from minimum 20Cm to maximum 2Km. Active technology has a high recognition rate in the environment of water and iron, which is the limitation of passive technology, and active technology has excellent scalability and interoperability with other technologies, and is the closest technology to the next-generation technology, that is, USN technology.

Currently, parking management system using RFID is composed of passive passive TAG, TAG reader installed at parking entrance and server which collects information received from reader and manages parking fee settlement and access status. The following is an example of the prior art as described above.

Republic of Korea Patent Publication No. 10-2006-0027105 is a parking management system using RFID, the connection control device recognizes and controls the fixed RFID tag installed on the floor of the parking area and the mobile RFID tag provided in the vehicle, and the central controller How to manage. The mobile RFID tag is issued to the parking ticket with the vehicle number recognized by the vehicle recognition camera, and the fixed RFID tag is installed on the floor of the parking area. When the mobile RFID tag is close to the parking area, the parking location confirmation terminal notifies the parking location of the vehicle. The RFID reader received through the plurality of antennas transmits a transmission signal for detecting a tag in a periodic polling manner, receives a tag information corresponding to the transmission signal, and transmits the response to the connection control device for time division multiplexing and transmission. It is also sent to a central link control unit for comprehensive analysis to manage parking status and available parking area. The prior art uses a passive RFID tag, the access distance is more limited than the active tag, and must rely on the parking confirmation terminal.

Korean Patent Laid-Open Publication No. 10-2006-0027105 also includes an RFID tag attached to a vehicle and transmitting tag identification information including vehicle information to a parking management system using RFID; A parking recognition unit installed in the parking space, receiving the tag identification information, extracting the vehicle information, and including at least one RFID transceiver for transmitting the reader identification information including the vehicle information; And a parking management unit that interprets vehicle location information in a predetermined parking space, parking presence information of a predetermined parking space, and information of a parked vehicle through the information received from the parking recognition unit. The parking recognition unit includes an image photographing device and a detection device, and generates a parking presence information by receiving a detection signal from the detection device, and when the vehicle parked from the detection device is detected but the tag identification information is not transmitted, the image. Operate the shooting device. In the prior art, a separate network technology is required in order to transmit data to a server by capturing an image with an image capturing device in consideration of a situation in which a signal of a sensing device is not accurately transmitted. Because of the limited range, multiple cameras have to be installed, which is expensive for large parking lots.

The present invention manages the parking surface in real time using Radio Frequency Identification (RFID) and Ubiquitous Sensor Network (USN), and provides real-time parking status to the driver, parking guidance, vehicle guidance, exit guidance, etc. To provide a parking management system and its method.

Using active RFID, ultrasonic sensor (indoor car park) and infrared sensor (outdoor car park), we can check whether there is a parking surface vehicle in the parking lot and manage the real-time parking surface information through the wireless network. To provide a 3D visualization-based parking guidance and management system that provides a variety of services.

In the case of a large parking lot, a large parking lot can't remember the parking location, which makes it difficult to find a car.The parking lot can be displayed using a flashing light or a status board. We propose a parking guidance system and method for intuitively guiding the route of the estimated area.

From the parking lot manager's point of view, the parking surface management system using RFID technology can detect the parking status in real time and accumulate the recognized information on the server to analyze the data. This paper presents an intelligent parking management system and method for accurately and systematically identifying location, parking fee, period fee, and long-term parking vehicle.

Here, the sensor is any one selected from a wireless ultrasonic sensor and an infrared sensor.

The parking management system further includes a vehicle location register connected to the router to register a location on the parking ticket.

In addition, the router is installed is connected to the parking lot indicating whether parking is possible on the parking surface.

The real-time parking surface management and 3D visualization based parking management method using RFID and USN according to the present invention recognizes that the vehicle is parked on the parking surface with a sensor when the vehicle is parked on the parking surface by receiving a parking ticket and uses the active RFID. Transmitting wirelessly using a module, receiving and relaying a signal from the active RFID module through a router, and managing parking information through a coordinator for integrated management of information received from the router; Storing the parking information from the coordinator on a server through a host, outputting and managing the parking lot status on the 3D visualization screen based on the information, and when the parking ticket is presented, the position and exit guidance of the vehicle through the 3D visualization screen. It comprises the steps shown.

Here, the management method further includes the step of guiding the empty parking surface through the 3D visualization screen before parking the vehicle.

Here, the mancha lamp connected to the router emits light to guide the location when guiding the empty parking surface.

According to the present invention, the vehicle entering for parking is the information of the server collected in real time, whether the parking space in the parking lot and the parking available position and the movement path is the same as the actual 3D parking lot model and the lighting device or LED installed in each parking area You can park quickly and easily without getting lost by checking and guiding. This saves time spent in the parking lot, and the effect will be even greater for large, complex parking lots. You can easily find your vehicle location, the location and direction of the exit you want to use, and because the parking date and time data of the vehicle is managed, the parking fee is automatically settled to smoothly manage the flow of the vehicle. This can eliminate the crowded commute time.

The parking manager can collect parking lot number, parking date and time of the vehicle, and the billing data automatically in real time to manage the parking quickly and efficiently with the minimum number of people. (The present invention can obtain more accurate information by using the active RFID module together to compensate for the shortcomings of the accuracy of the passive RFID module, and do not need to install multiple cameras to compensate for the accuracy when using the passive RFID module. Installation cost can be reduced.)

The present invention recognizes and manages the presence of parking spaces in a parking lot in real time using RFID and USN technology, and provides various services such as parking status monitoring, parking guidance, vehicle finding, exit finding, etc. It relates to a parking management system provided and its method.

The system according to the present invention includes an ultrasonic / infrared sensor for recognizing the presence or absence of a vehicle attached to the upper or rear surface of each parking surface; An active RFID module attached to the sensor for wirelessly transmitting the recognized parking information; Router which is a wireless transmission repeater; Coordinator integrated management of parking information collected from the repeater; Real-time parking surface management system for integrated management of the real-time parking information collected from the hardware and the Coordinator using RFID and USN technology consisting of; It consists of a 3D viewer system that supports parking status monitoring, vehicle search and exit guidance through 3D shape visualization.

The active RFID module of the hardware using RFID and USN technology detects the presence of a vehicle by attaching an ultrasonic sensor or an infrared sensor and transmits and receives information to and from a router. It is attached to each parking surface in the parking area. It is equipped with its own battery to enable wireless communication without additional power supply, and transmits and manages data periodically or at specified times.

The parking area refers to an area divided in order to efficiently manage the parking lot in consideration of a vehicle moving path and facilities in the parking lot, and may be divided into one or more areas. One parking area consists of a plurality of parking surfaces. The criterion can be a parking post, and the parking zone is the area that manages the vehicle between the parking posts and can be managed with the ID or number of the parking post. The parking surface is a parking space for stopping a vehicle.

The ultrasonic sensor and the infrared sensor are wireless sensors. The ultrasonic sensor is attached to the upper surface of the parking lot in the indoor parking lot to generate ultrasonic waves, calculate the time difference reflected and return to recognize the distance. The range detection range is adjustable and can be up to 1.8m. The infrared sensor is attached to the rear of the parking lot for outdoor parking lot to reflect the infrared rays to the object and the amount of incoming light changes the amount of voltage to recognize parking.

The router functions as a repeater to receive wireless communication data generated from an active RFID module within at least one of the available reception ranges in the parking lot and transmit the information to the coordinator to position information. It is desirable to install it together with a vehicle location register and a full car using a router on each parking column. The vehicle location register may record the parking location information in the parking ticket to find its own vehicle location, find an exit to use, and guide the movement route to the corresponding location through the 3D viewer system. The full lamp is a guide light indicating whether parking is available in the parking area, but receives a signal from the server, and determines whether the tolerance is displayed.

The coordinator transmits wirelessly transmitted information from a router to a host connected to each other. The host accesses the coordinator and receives all data of the coordinator and delivers it to the server.

The server analyzes the data received from the host and stores it in a database (DB). This information is optimally managed by real-time parking status in the parking surface management system and is synchronized in real time when requested by the 3D viewer system.

The parking surface management system (see FIGS. 6A and 6B) may be divided into a parking area, a parking column, a parking surface, and a parking state. Parking zone management manages information such as parking zones, router IDs, whether there are full cars, how many parking zones are used, and parking zones can be added, modified, or deleted. Parking surface management can know the information of the relevant parking surface according to the parking area, manages parking location, sensor ID, parking surface parking status, parking time, parking area information, and can add, modify, delete the parking surface. In addition, 3D viewer can check the parking status of the parking area and the parking surface.

The 3D viewer system (refer to FIGS. 7A to 7E) is a 3D parking lot visualization model that displays a parking status, a viewer for guiding a moving route, and an interface for feeding back user requests. An LCD display device and a monitor installed inside the parking lot (Kiosk ) Provides the user with real-time parking status. The viewer's main functions include parking area view, parking column number view, parking plane view, parking status view and view control functions such as standard view, position movement and horizontal movement. For the user's convenience, the viewer's detailed path finding function includes find a car's position pillar, find an exit, and find a parking surface for parking. The viewer can be informed of the moving route from the current location to the destination.

The path of the route that the user wants to find can be simulated by the view from the top, the 3D view and the map view. Each view can be provided with a Bird's Eye View.

The 3D parking lot visualization model used in the 3D viewer system requires a preliminary operation of producing a 3D visualization model with a drawing of the parking lot in order to provide a realistic moving route guidance to the user.

The LCD display device installed inside the parking lot is preferably installed at the entrance of the parking lot to the user's field of view to inform the parking spot when the user enters the parking lot, and the monitor (Kiosk) is used for the purpose of finding the exit and vehicle. It is desirable to install with a stand type touch screen at frequent entry and exit.

The method according to the invention is as follows.

Parking management method on the side of the system proceeds to the step shown in FIG. When the vehicle enters the parking surface, the ultrasonic / infrared sensor attached to the upper parking surface detects the presence of the vehicle. Tag receives recognition information of sensor, Tag delivers to Router, Router delivers to Coordinator. The host receiving the information of the coordinator collects the parking side information and stores it in the DB of the server. The parking surface management system analyzes and optimizes the parking status by receiving the parking surface management information from the server in real time. When the user requests information such as parking guidance, vehicle finder, and exit finder, the 3D viewer system guides the available parking surface, the vehicle position, and the exit position through the 3D parking lot model.

Parking guidance method of the user side proceeds to the step as shown in FIG. The user is issued a parking ticket at the entrance of the parking lot. After checking the parking status in the parking lot through the 3D viewer system of the large LCD display device, check the parking surface available for parking and enter the parking lot. Park the vehicle after checking whether the parking lot is full. The user registers the current vehicle position in the parking ticket by approaching the parking ticket to the vehicle location register. After using the building, Kiosk's 3D viewer system, which is installed in various places, recognizes the parking ticket and requests the location and exit of the vehicle, and the user can be guided through the 3D parking lot visualization model.

Parking management method of the manager side proceeds to the step as shown in FIG. The manager manages the real-time parking status through the parking surface management system. The parking surface management system is started to connect to the server and receive real-time parking surface management information from the server. The manager can manage by adding, modifying and deleting parking zones and parking planes based on the parking posts, and checking the current or accumulated parking status through the 3D parking lot visualization model. Also, it checks the reception status of hardware such as sensor, tag, router and coordinator to manage the hardware and manages parking by accumulated parking time and parking fee.
