The present invention relates to an intelligent parking management system, and more specifically, it is possible to grasp the parking situation including parking availability and its own vehicle location by using RFID which can be used semi-permanently, and parking the vehicle according to the parking situation. An intelligent parking management system that leads to space.

Currently, research on RFID (Radio Frequency Identification) is progressing rapidly around the world, and standardization related to RFID is expected to be completed by ISO, an international standardization organization, by the end of 2004. Since 2005, large discount store companies such as Wal-Mart in the United States, Tesco in the UK, and Metro Group in Germany have been using RFID to store goods in and out of the store, to manage the price of purchased items, and to supply scarce items. In fact, Wal-Mart has been demanding that the top 100 companies that ship to it be attached with RFID tags since 2005. With this trend, it is predicted that as the use of RFID expands, the price of the system and tag of RFID decreases and it can be used at a very low price.

On the other hand, in the general parking system, when the vehicle enters the parking lot and the paper parking card is removed from the entrance, the blocking device is opened, the vehicle enters the parking lot, and the vehicle is parked in an empty place by the driver's judgment or the guidance of the parking management personnel. All. In this case, a paper parking card including a magnetic tape, which is widely used in general, collects a parking fee by recording the time of receipt of the vehicle and calculating the parking time at the time of shipment. A parking card with a plastic card is similar in function, recording the time on magnetic tape to calculate the parking time.

The problem with conventional parking systems is that the driver must remember the parking position of the vehicle correctly. If you don't remember it correctly, you'll spend a lot of time figuring out where your car is parked, and if a lot of people are going to do it, that's a lot of economic loss. However, there is almost no way to determine the location of the vehicle with the existing parking system, even if the situation is quite inconvenient for ordinary drivers.

The second problem is environmental pollution and waste of resources from the disposable use of paper parking cards. Plastic parking cards are also used, but plastic cards also need to read magnetic tapes. These close-up magnetic tape RFID readers have difficulty reading data when the magnetic tape portion is contaminated. This disadvantage is a common problem of contact cards.

The third problem is that parking management agents are separately arranged and operated in large discount stores or department stores. This requires a separate labor cost for parking management.

Accordingly, an object of the present invention is to automatically determine the location of the parked vehicle by using the RFID so that even if the driver does not remember the position of the vehicle accurately by mapping the parking position of the vehicle to the vehicle number through a monitor installed in the parking lot It can be quickly identified, and since the parking card using the RFID tag can be used repeatedly many times, it can not only greatly reduce the cost of parking management but also provide an intelligent parking management system that can reduce environmental pollution.

In addition, the present invention can determine the presence of the parking space in real time due to the use of this system can automatically guide the parking using a direction indicator, etc. for vehicles entering the parking lot, thereby managing a separate parking Its purpose is to provide an intelligent parking management system that can improve the efficiency and economics of parking management by eliminating the need for personnel.

Accordingly, the present invention has been made to solve the problems of the prior art, an object of the present invention is to read the vehicle number received in the parking lot to issue a storage tag mapped to the vehicle number, the unique number of the storage tag And a control module which performs mapping processing of the information recorded in the storage tag, and processes the parking situation data transmitted from the storage tag reading means described below. Storage tag reading means connected to the control module through a network to read the storage tag and transmit the reading to the control module; And it is connected to the control module to provide an intelligent parking management system comprising a monitoring means for monitoring the parking situation data transmitted from the storage tag reading means.

Hereinafter, the intelligent parking management system of the present invention will be described in detail with reference to the accompanying drawings.

1 shows a system in plan view assuming a parking lot. Referring to FIG. 1, the image scanner 102 acquires vehicle information by image scanning the license plate of the vehicle after the entry of the vehicle 101 is detected, and inputs it to the RFID tag. It is assumed that a sensor for detecting entry of the vehicle 101 belongs to the image scanner 102.

The ticketing machine 104 functions to input the vehicle number collected from the image scanner 102 to the RFID tag, and issue the RFID tag as a parking card.

Here, there are various kinds of RFID tags, and since the information is included in the tag at the time of manufacture, the contents of the tag cannot be modified, and there is no information at the time of manufacture, but after recording arbitrary contents in the tag for any purpose, There are types that can't be changed and types that can be written to and read from tags whenever needed. The RFID tag used in the present embodiment uses a tag capable of writing and reading like the above-described third type of memory, erasing the previous contents, rewriting and repeating the reading thousands of tens of thousands.

At this time, the main controller 103 maps the unique number of the RFID tag and the input vehicle number, and stores the mapping information in the database 105 to instruct ticketing. In addition, it functions to collect and determine the information from the RFID reader 108, and a comprehensive function such as guiding the vehicle to an empty position by using the direction indicator 106 in the parking lot.

The RFID reader 108 collects a vehicle number parked from the plurality of antennas 109 and transmits the collected vehicle number to the main controller 103. At this time, the antenna 109 is installed in an appropriate position in consideration of the propagation characteristics in order to minimize the interference between the antenna 109 and the interference between the RFID reader 108.

The RFID reader 108 and the antenna 109 are generally connected by wire, and the connection between the RFID reader 108 and the main controller 103 and the connection between the monitor 111 and the main controller 103 may be wired or wirelessly. Can be connected. The monitor 111 is a device for the driver to return to the parking lot after finishing work to determine the location of his vehicle, and the device has an input device 112 such as a keyboard and provides an interface function for inputting his / her vehicle number.

The operation method of the intelligent parking management system using the RFID of the present invention configured as described above will be described.

When the vehicle 101 enters the parking lot, the image scanner 102 that detects the arrival of the vehicle 101 determines the vehicle number by scanning the license plate of the vehicle. This vehicle number is reported to the main control device 103, and the main control device 103 causes the ticketing machine 104 to input this vehicle information into an RFID tag waiting in the ticketing machine 104. The main controller 103 maps the unique number of the RFID tag and the vehicle number and stores them in the database 105. The vehicle 101 to which the parking card has been issued parks in an empty position according to the direction indicator 106. The direction indicator 106, which functions to guide the vehicle to an empty parking position, is also controlled by the main control device 103.

The RFID reader 108 installed in the parking lot from the RFID tag, which is the parking card in the vehicle 107 parked at the proper position, collects the information of the tag through the antenna 109 connected to each RFID reader 108. do. The vehicle number collected by the RFID reader 108 is transmitted to the main control unit 103 via the wired / wireless network 110 together with the parking position information, and the information is stored in the database 105.

On the other hand, the driver who completes the work inputs his vehicle number to the monitor 111 installed in the parking lot or at the entrance, which is a request command to the main controller 103. The main controller 103 transmits the parking position information of the corresponding vehicle number from the database 105 to the monitor 111 so that the driver can check the position of his vehicle 107. Such message transmission may also be performed in a wired or wireless manner.

2 is an operation flowchart of an intelligent parking management system. Referring to FIG. 2, when power is supplied to the system, operation of the system is started (201). Once the operation has started, it remains in standby mode 202 once. Periodically checking whether the vehicle is in stock (203), if there is no vehicle entering, maintaining the standby mode (202) again, and scanning the vehicle number (204) if there is an entering vehicle (101). Enter The recognized vehicle number and the receipt time are recorded in the RFID tag (205). Along with this vehicle information, the unique number of the RFID tag is stored in the database 105 (206). After that, the RFID tag is issued as a parking card and the vehicle to which the RFID tag is attached is guided to the empty position in the parking lot by the direction indicator 106 (207). The direction indicator 106 functions to indicate the direction so that the vehicle 101 can be guided to an appropriate position. After the vehicle 107 is parked, the RFID reader 108 at the closest position recognizes the vehicle number and the like from the parking card of the vehicle 107 and transmits the vehicle number to the main controller 103 together with the parking position information (208). ). The RFID reader 108 periodically checks whether the vehicle is parked in the area in charge and transmits it to the main controller 103 (209). When the driver finishes the work outside the parking lot and returns to the parking lot and leaves the vehicle 107 (210), the driver may recognize the time information from the parking card to calculate the parking fee (211). If the operation of the parking management system is not necessary, the operation is terminated (212).

3 is an operation flowchart of the monitor. Referring to FIG. 3, when power is supplied to the monitor 111, operation starts (301). When the driver enters the standby state initially (302), and the driver returns to the parking lot after entering the vehicle number (303), a signal for requesting the vehicle position from the monitor 111 to the main controller 103 is received. Is sent (304). The main control unit 103 finds the vehicle position information from the database 105 and transmits it to the monitor 111 (305). The monitor 111 displays the received vehicle location information on the monitor 111 to provide information required by the driver (306). If the operation of the monitor 111 is unnecessary, the operation is terminated when the power is removed (307).

As described above, the intelligent parking management system according to the present invention applies the RFID tag and the system even if the driver temporarily cannot remember the parking position of the vehicle in the parking lot. The location can be easily determined, and the vehicle guidance can be automatically performed, so that a great socioeconomic effect can be obtained in terms of management and use of the parking lot.

This is because the recent large discount stores or large buildings to operate a larger parking lot than the existing effect of the present invention will be even greater. In addition, since the parking card using the RFID tag can be repeatedly used many times, it is possible to greatly reduce environmental pollution and maintenance costs compared to the conventional disposable paper parking card.

By using this system, the presence of parking space can be grasped in real time, so it is possible to promptly guide parking by using direction indicators for vehicles entering the parking lot, thereby reducing the number of separate parking management personnel. As a result, labor cost savings from parking lot management can be obtained. As a result, the efficiency and economics of the parking lot management task can be improved.
