In addition, it is possible to check the position of the parked vehicle in the parking lot through the parking locator 40 linked to the main processing apparatus 1.

2 and 3 illustrate a conventional image recognition method and a method of recognizing the RF card of the present invention in a vehicle recognition method and a vehicle identification method, respectively.

FIG. 4 is a view illustrating an operation of reciprocating in a sector as an additional device for each RF card recognition in a parking space for each sector in the parking control system of the present invention. FIG. The vehicle identifier / car number identifier or RF card reader 2 is arranged at the entry / exit intersection of the sectors.

FIG. 6 shows that the vehicle identifier / car number identifier or the RF card reader 2 for the vehicle identification for each floor of the present invention is arranged at the entrance and exit.

The following sequence shows the steps of operating the parking control system composed of the above devices of the present invention in connection with the movement of the vehicle at the time of entering and parking the vehicle, and at the time of leaving the vehicle. The method has been mainly described. Hereinafter, control of all devices in the loading / unloading / carrying process is performed by processing the information transmitted from the devices in the main processing device 1.

<< when entering >>

1) In the case of a vehicle with an RF card, the vehicle number is read by the RF card reader (2b), or the vehicle number is automatically scanned by a manual input or a car number recognizer disposed at the entrance and the like, and this information is sent to the main processing device (1) for registration. Check the vehicle's identity.

2) In the case of a registered vehicle (fixed, fixed amount, free, preferential), the entrance breaker (13) is opened to allow entry into the vehicle immediately,

3) If the vehicle is not registered, issue a new RF card. At this time, the unique number of the RF card and the vehicle number are matched and input to the main processing apparatus 1, and after issuance, entry is allowed.

4) Induces a vehicle by allocating an empty parking space from the main processing apparatus 1 and displaying the parking sector and the driving direction on the guide lamp 23 or the electric sign 22 in the parking lot, which is the parking-related apparatus 20,

5) The vehicle driver visually checks the vehicle guidance apparatuses, proceeds and moves into the corresponding sector, enters an empty parking space within the sector, and parks the vehicle.

At this time, the information of the vehicle moved by the RF card reader 2b installed in the entry / exit path of the sector is reported to the main processing device 1 from time to time, and it is updated and recorded which floor and which sector the vehicle is in at any time. .

<< departure

6) Information of the moving vehicle is reported to the main processing apparatus 1 by the RF card reader 2b installed in the sector exit path in the same manner as when the vehicle starts to start the departure along the exit direction indicated on the ceiling or the road surface.

If the vehicle is not a departure, but a simple movement, the main processing apparatus 1 can determine which RF card-bearing vehicle or which vehicle number exists in which sector.

8) When leaving the vehicle, check the vehicle information with the RF card or the vehicle number provided to the vehicle.

9) Allow the vehicle to be departed after returning the confirmed RF card or the fare settled.

In the above, the information read by the RF card issued at the time of entry / exit can recognize the movement information of the vehicle more accurately and quickly because of the higher readability than the information read by the vehicle / car number recognizer 2a of the conventional image scanning method. A much more efficient parking management system is possible.

Examples of RF cards that can be used for this purpose include RF-IC cards that can read and write vehicle parking information by contactless RF-ID cards that can simply read the serial number in the card or IC cards embedded in the cards. have.

In the above, the RF card reader 2 may be replaced and mixed with the vehicle / car number recognizer 2a of the image recognition method, and the like, and the vehicle including the RF card reader 2 and the image recognition vehicle / car number recognizer 2a. In the installation of the vehicle identification device 2, as shown in FIG. 5, the parking space in the parking lot is grouped into several sectors as shown in FIG. 5, and the vehicle is divided into the necessary entry / exit passage points of these sectors. If the vehicle number recognition device 2 is provided, only the few vehicle / car number recognition devices 2 can easily determine the movement information of the vehicle.

In addition, when only the floor-level management is required in a multi-storey parking lot, the vehicle / car number recognition device 2 is installed only at the entrance and exit of each floor to detect only vehicles entering and entering the floor.

This method not only has an advantage of reducing installation costs than installing the vehicle / car number recognition device 2 separately for each parking space, but also counts the number of vehicles entering and leaving the corresponding sector during entering and parking. The system guides the vehicle by notifying only the number of empty parking spaces in the sector or on the floor, or detects vehicle information entering and exiting the sector or the floor, and detects the vehicle information. Ideal for building systems that can only report parked sectors or parking floors.

In addition, as shown in FIG. 4, if an additional in-sector management apparatus for reading a vehicle information parked in each parking space is arranged as shown in FIG. 4, the same effect as that of the existing parking location checking system for each parking space is achieved. It is also possible to construct a more economical system.

The sector / floor vehicle / car identification apparatus 2 as described above is a very advantageous method that can be applied to installing not only an RF card reader but also other vehicle and vehicle identification apparatuses.

The information recorded in the main processing device of the parking control system of the present invention as described above may be utilized for the following purposes.

1) Using the information of all vehicles from entering and leaving to the fare calculation data, the database is built and used for various report work and data analysis, and can be used as cross check data in the amount of fee income.

2) In the case of regular parking registered as a preferential customer, a separate RF card may be distributed in advance, and the system may be constructed to immediately recognize the RF card when entering and exiting the parking lot of the vehicle and to immediately enter and exit the parking lot.

3) The main processing unit can be managed separately in case of theft or other inaccessible vehicles by linking with the database of the government office, and if the corresponding number is recognized at the time of entry, it can be notified to the operator to enable emergency processing.

4) In the existing unmanned parking control system, long-term parking had difficulties in determining the parking time of the vehicle (when the parking ticket is lost), but this problem can be solved because the system recognizes the license plate of the vehicle.

By using the sector-by-sector parking management method as in the present invention, it is possible to reduce the number of parking control devices for vehicle management of the parking lot, thereby reducing the installation cost, and the method using the RF card of the present invention images the license plate. It can have a better reading rate than the reading method, which allows more accurate parking control.

Based on this, the accuracy can be increased when checking the parking position, which is effective for increasing customer satisfaction.
