  The operation of the present embodiment having the above configuration will be described with reference to the flowcharts shown in FIGS.

  That is, the management server 31 calculates the position of the ID tag 34 as a position coordinate from the difference in arrival time of radio waves from the ID tag 34 provided on the vehicle 2 to the location receivers 61 to 64, and stores the database. In the parking position guidance process, it is determined whether there is a vehicle 2 approaching the entrance 32 from outside the parking lot 3 from the position coordinates stored in the database (S1). If there is no vehicle 2 that approaches the main routine, the process returns to the main routine. On the other hand, if there is a vehicle 2 that approaches the entrance 32, the ID of the card provided in the vehicle 2 by the input device of the first controller 33. The ID number is read from the tag 34 and waits until the ID number is sent via the LAN 71 (S2).

  Thus, it is possible to detect that the vehicle 2 is approaching without providing a vehicle sensor at the entrance 32 of the parking lot 3. Similarly, it is possible to detect that the vehicle 2 is approaching without providing a vehicle sensor at the exit 51 of the parking lot 3.

  Thereby, the driver who drove the vehicle 2 to the vicinity of the designated parking space 11 can grasp the parking position by the group lights 13 to 16 and the garage number light 21 that are turned on.

  Thus, since the empty parking space 11 can be notified to the driver of the vehicle 2, the driver can easily grasp the parking space 11 that can be parked without going around the parking lot 3. And smooth parking is possible. On the other hand, the manager of the parking lot 3 can smoothly guide the vehicle 2 to the empty parking space 11, and can be operated smoothly.

  Then, the vehicle 2 is parked in the parking space 11. Then, the position coordinates of the ID tag 34 provided on the vehicle 2 indicate the position of the parking space 11, and the management server 31 confirms that the vehicle 2 is parked in the designated parking space 11. Since it is possible (S6), the group lamps 13-16 and the garage number lamp 21 are transmitted by transmitting a turn-off signal via the LAN 71 to the group lamps 13-16 of the group and the garage number lamp 21 of the number. The light is turned off (S7).

  When parking in the parking space 11 is completed (SB1), the push button switch of the card incorporating the ID tag 34 is operated to switch from the security off state to the security on state, and from the ID tag 34, A message to that effect is transmitted on the radio wave (SB2).

  Then, the radio waves are received by the location receivers 61 to 64, and from the location receivers 61 to 64, the fact that the ID tag 34 has been switched to the security on state is sent to the management server 31 via the LAN 71. In the management server 31 that has been transmitted and received, the fact that the ID tag 34 is in the security-on state is stored in the database in association with the ID number of the ID tag 34 (SB3).

  Next, the management server 31 monitors whether there is a change in the position coordinates of the ID tag 34 in the parking lot 3 recorded in the database (SB4). If there is an ID tag 34 with a change in position coordinates, it is determined by searching the database whether the ID tag 34 is in the security-on state (SB5).

  When the position coordinates of the ID tag 34 in the security-on state are changed and the vehicle 2 having the ID tag 34 has been moved, the vehicle 2 is taken out by a third party without permission, that is, theft has occurred. Can be expected.

  In this case, the mail address of the user terminal 75 used by the user associated with the ID number stored in the ID tag 34 and the mail address addressed to the user are extracted from the database, and the vehicle 2 moves. A mail to the effect is created, and the mail is transmitted to both mail addresses via the Internet 81 (SB6).

  Thereby, the user of the said vehicle 2 can know that the vehicle 2 was moved, and in this user, the response | compatibility of returning to a parking lot or contacting an administrator etc. can be performed rapidly. .

  Thus, the state of the vehicle 2 in the parking lot 3 can be managed as the position coordinates of the ID tag 34 provided on the vehicle 2. As a result, as described above, it can be used for grasping where the target vehicle 2 is located, entering or leaving the parking lot 1, and the presence or absence of an empty parking space 11. improves.
