The processing to be executed is shown.
[0035]
When a user uses a parking lot or a hotel / theme park, the user makes a reservation using the user terminal UM prior to the use. Specifically, the user terminal UM is connected to the reservation operation system via the communication network TN, and a reservation is made by inputting predetermined items. At this time, the reservation operation system RS executes the processing shown in FIG.
[0036]
First, in step 110, a process for inputting necessary items is executed. That is, a format for describing the user usage information is displayed on the display of the user terminal UM, and the blank portion is filled by the user.
[0037]
Then, the process proceeds to step 120, where it is determined whether or not there is an input omission in a blank portion. If there is no input omission, the process proceeds to step 130. If there is an input omission, the process returns to step 110 again. Is described.
[0038]
In step 130, it is determined whether or not the user is a parking lot user based on the input user usage information. If the user is a parking lot user, the vehicle information of the user is registered in the reserved vehicle management DB 5 in step 140, and the process proceeds to step 150. If the user is not a parking lot user, the process directly proceeds to step 150.
[0039]
In step 150, it is determined whether or not the user is a hotel / theme park user based on the input user usage information. If the users are those users, the hotel / theme park use information is registered in the user reservation management DB 6 in step 160, and the process is terminated. If the user is not a hotel / theme park user, the process ends.
[0040]
Next, when the user makes a parking lot reservation and then comes to the entrance gate of the parking lot with the vehicle 1, the electronic license plate communication device 4 of the entrance gate and the parking lot reservation management system PS are shown in FIGS. The processing shown in is performed.
[0041]
First, as shown in FIG. 3, the electronic license plate communication device 4 determines whether the vehicle 1 has entered the communication area of the electronic license plate communication device 4 in step 210. This is performed based on a detection signal from a vehicle sensing unit such as the optical sensor described above. If the vehicle 1 has entered the communication area, the process proceeds to step 220, and if not, the process is repeated.
[0042]
In step 220, a process of acquiring communication start vehicle information is executed. That is, since a radio wave including vehicle information is emitted from the electronic license plate 2 in response to the radio wave emitted from the electronic license plate reader 4c, the electronic license plate reader 4c receives the radio wave. The received radio wave including the vehicle information is converted into a signal by the electronic license plate reader 4c and sent to the data processor 4d.
[0043]
Then, in step 230, based on the communication result of the electronic license plate reading device 4c, it is determined whether or not the data processing device 4d receives the vehicle information and performs communication. Thus, if the communication has failed, the above processing is repeated again. If the communication has succeeded, the process proceeds to step 240, and the vehicle information is acquired from the signal received by the data processing device 4d.
[0044]
In the subsequent step 250, a signal including vehicle information is transmitted from the data processing device 4d to the parking lot reservation management system PS.
[0045]
On the other hand, when the signal including the vehicle information is transmitted from the data processing device 4, the parking lot reservation management system RS acquires the signal from the data processing device 4d as in step 310 shown in FIG. Then, in step 320, the parking lot reservation information list registered in the reserved vehicle management DB 5 is searched and collated with the received vehicle information.
[0046]
In step 330, it is determined whether or not the vehicle 1 is a reserved vehicle for which a parking lot has been reserved by the user first, based on the collation result in step 320. If the vehicle is a reserved vehicle, the process proceeds to step 340 to send a reserved vehicle exclusive gate guidance instruction, that is, a guidance instruction signal for guiding to a reserved vehicle exclusive parking lot and an opening / closing instruction signal for opening a gate to the data processing device 4d. . If the vehicle is not a reserved vehicle, the process proceeds to step 350, and a general vehicle dedicated gate guidance instruction, that is, a guidance instruction signal for guiding to a non-reserved vehicle parking lot is sent to the data processing device 4d.
[0047]
When these instruction signals are sent from the parking lot reservation management system PS, the data processing device 4 acquires the instruction signals from the parking lot reservation management system PS as in step 260 shown in FIG. In step 270, it is determined whether or not the vehicle 1 is a reserved vehicle based on each instruction signal. If the vehicle is a reserved vehicle, in steps 280 and 290, an instruction to guide to the reserved vehicle dedicated gate is sent to the electric bulletin board 4b. , And a process of opening and closing the gate 4a. If it is not a reserved vehicle, in step 300, an instruction for guiding to the gate dedicated to the back of a general vehicle is indicated on the electronic bulletin board 4b.
[0048]
Thereafter, after the user parks the vehicle 1 in a predetermined parking lot, the user goes to a hotel or a theme park, and the user provided in the parking lot reservation management system PS determines whether or not the user has made a reservation at those front desks. The user checks the reservation management DB 6 and uses the reserved hotel or theme park.
[0049]
Subsequently, when the user arrives at the exit gate of the parking lot by using the vehicle 1 after using the hotel or the theme park, the electronic license plate communication device 4 of the exit gate and the parking lot reservation management system PS are shown in FIGS. 6 is performed.
[0050]
First, as shown in FIG. 5, the electronic license plate communication device 4 executes the same processing as that shown in steps 210 to 250 in FIG. 3 in steps 410 to 450. Through these processes, a signal including vehicle information is transmitted from the data processing device 4d to the parking lot reservation management system PS.
[0051]
When a signal including vehicle information is transmitted from the data processing device 4, the parking lot reservation management system PS executes the same processing as that shown in FIG. 4 in steps 310 and 320 shown in FIG. Thereby, the registered contents of the parking lot reservation information list in the reserved vehicle management DB 5 are compared with the vehicle information received from the data processing device 4d.
[0052]
Then, in step 530, it is determined whether or not the use time of the parking lot by the vehicle 1 is within the reserved time based on the collation result in step 520. If it is within the reservation time, the process proceeds to step 540, where an opening / closing instruction signal for opening the gate is sent to the data processing device 4d. If the time has exceeded the reservation time, the flow advances to step 550 to send an additional charge request signal indicating the amount of additional charge charged to the data processing device 4d.
[0053]
When these instruction signals are sent from the parking lot reservation management system PS, the data processing device 4 acquires the instruction signals from the parking lot reservation management system PS as in step 460 shown in FIG. Then, in step 470, it is determined whether or not the use time of the vehicle 1 is within the reserved time based on each instruction signal, and if it is within the reserved time, in step 480, a process of opening and closing the gate 4a is performed. If it is not within the reservation time, the additional charge is displayed on the electronic bulletin board 4b in step 490, and the process proceeds to step 380 to open and close the gate 4a.
[0054]
If the user has used the parking lot for longer than the usage time, the user information is known in advance at the time of the reservation, so that an additional fee can be charged by electronic payment or the like.
[0055]
As described above, in the parking lot reservation management system shown in the present embodiment, the user usage information input by the user using the user terminal UM is stored in advance in the reservation vehicle management DB 5 via the communication network TN and the reservation operation system RS. And registered in the user reservation management DB 6. When the user arrives in front of the electronic license plate communication device 4 at the entrance of the parking lot reserved by the vehicle 1, the electronic license plate reader 4c receives the radio wave including the vehicle information from the electronic license plate 2 after receiving it. By searching the parking lot reservation information list in the reserved vehicle management DB 5 and collating it with the received vehicle information, it is determined whether or not the vehicle 1 belongs to the user who made the reservation.
[0056]
Therefore, even if the user does not have a membership card such as an IC card in advance, it is possible to determine whether or not the vehicle is the vehicle 1 of the user who made the reservation based on the information from the electronic license plate 2 and use the parking lot. It is possible.
[0057]
On the other hand, when the user finishes using the parking lot and arrives at the exit gate in front of the electronic license plate communication device 4 at the exit gate, the vehicle 1 is identified by the same processing as the entrance gate and added according to the usage period of the parking lot. Processing such as billing of fees is performed. For this reason, when leaving the parking lot, even if you do not own a membership card, a parking lot use card, or the like, it is possible to perform the processing required to exit the parking lot.
[0058]
(Other embodiments)
In the above embodiment, the parking lot is reserved via the Internet. However, the present invention is not limited to the Internet. For example, even when the user makes a parking lot reservation using a telephone or the like, by registering the vehicle information of the user in the reserved vehicle management DB 5 in advance, when the user uses the parking lot, Even if the user does not own a membership card or the like, it can be determined whether the vehicle is a reserved vehicle. Thereby, the same effect as the above embodiment can be obtained.
[0059]
Further, in the above embodiment, the example in which the electronic license plate communication device 4 to which the embodiment of the present invention is applied is arranged at each of the entrance gate and the exit gate of the parking lot, but it is not always necessary to apply to both. . For example, if the present invention is applied to an entrance gate, a reserved vehicle for a parking lot can be specified, and if the present invention is applied to an exit gate, it can be used to determine the parking lot use time of the vehicle 1. In this case, the parking lot use time can be calculated by storing the vehicle information of the electronic license plate 2 read at the entrance gate and the parking lot entry time.
