Description

  The present invention relates to a parking lot entry / exit management system, and more particularly to a system and method for managing entry / exit in a parking lot using wireless communication.

  In recent years, labor costs have been reduced in parking management, and unmanned parking has become widespread. FIG. 1 shows a typical configuration example of a billing system in conventional unmanned parking management. As shown in FIG. 1, the general vehicle 10 temporarily stops in front of a ticket issuing machine 12 installed at a parking lot entrance. The driver 11 of the vehicle 10 lowers the driver's seat window, presses the ticket issuing button of the ticket issuing machine 12, and the ticket issuing machine 12 issues a ticket (parking ticket) 13 describing the current time (entry time). When the driver 11 receives the ticket 13, the warehousing management system 14 raises the entrance gate (breaker), permits passage of the vehicle 10 and notifies the warehousing management database 15 that the warehousing has occurred. After confirming that the entrance gate is raised, the driver 11 enters the parking lot 1 and parks the vehicle 10 in the empty parking space. The driver 11 closes the window of the vehicle 10 and stops the engine, and then stops the parking lot. Leave from 1.

  At the time of delivery, the driver 11 returns to the parking lot 1, gets on the vehicle 10, and heads for the parking lot exit. The vehicle 10 temporarily stops in front of the checkout machine 16 installed at the parking lot exit, and the driver 11 lowers the driver's seat window and inserts the ticket 13 into the checkout machine 16. The settlement machine 16 calculates the parking time of the vehicle 10 based on the time described in the ticket 13 and outputs the parking fee for the parking time on the display of the settlement machine 16. The driver 11 pays the parking fee, receives the change when there is change, and the settlement machine 16 notifies the delivery management system 17 when the settlement is completed, and the delivery management system 17 receives the notification of the completion of the settlement, and the exit gate The vehicle 10 is allowed to leave, and at the same time, the entry / exit management database 15 is notified that the vehicle 10 has been delivered. The driver 11 confirms that the exit gate has been raised, and the vehicle 10 leaves.

  For example, Patent Document 1 discloses a parking lot management system using ETC (Electric Toll Collection). This is because the first data communication device receives the vehicle information from the vehicle-mounted device of the ETC vehicle to be stored using the storage management database in the existing parking management system, and opens the input gate by the storage management system. When the second data communication device receives the vehicle information from the vehicle-mounted device of the ETC vehicle heading to the ETC vehicle heading to the exit gate, allowing the entry of the ETC vehicle, the exit management system corresponds to the vehicle information. The time information is read out from the warehousing management system, the parking fee is calculated by the settlement machine, displayed on the display unit, and when the payment of the parking fee is confirmed, the exit gate is opened and the ETC vehicle is allowed to leave. The parking lot management system of Patent Document 1 differs from the present invention described later in terms of the communication method (RADIUS protocol) and the presence or absence of a security management function.

  Patent Document 2 includes a parking lot management system including a server device that manages parking information, and a plurality of wireless LAN base stations that transmit and receive parking information wirelessly in a parking lot, A wireless LAN system is configured wirelessly within a transmittable / receiveable range, and the parking lot management system communicates parking information between a plurality of wireless LAN base stations and a server device via an IP network using an Internet protocol. The structure provided with this is disclosed. The system described in Patent Document 2 is different in terms of security management functions.
