In the parking lot management device 60, the usage status acquisition unit 643 acquires the vehicle entry information and the vehicle exit information transmitted from the vehicle detection sensor 20, and recognizes the usage status of each compartment B.

[0030] As information for user X to reserve the use of parking lot P on user terminal 50, user 00'' and usage time information ``2 hours'' and perform an operation to request a usage reservation, the user terminal 50 generates usage reservation request information based on the input information and the parking lot management device 60 Send to.

[0031] In the parking lot management device 60, the reservation processing unit 641 acquires parking lot P utilization reservation request information from the user terminal 50. Upon acquiring the usage reservation request information, the reservation processing unit 641 identifies the cabin B-1 that user X should use based on the usage reservation request information, associates it with the acquired information, and makes a reservation as reservation information. The information is stored in the information storage unit 632.

[0032] Here, when user The vehicle compartment may also be specified. In addition, if the vehicle used by User Information specifying that the use of X involves getting in and out of a wheelchair is also input, and based on this information, the reservation processing unit 641 selects cabin B, which has a large area that makes it easy for a wheelchair user to get on and off, or A compartment B that is close to the entrance F that is easy to move to the store may be specified.

[0033] When the warehousing prevention device control unit 642 detects that a predetermined time, for example, 30 minutes before the use start date and time of “2022 / 02 / 01 15:00” of the reservation information stored in the reservation information storage unit 632, In order to secure the vehicle interior, regardless of whether the current state of the vehicle entry prevention member 12 is raised or lowered, the vehicle entry prevention device 10 installed in the corresponding vehicle compartment B-1 issues an instruction to raise the vehicle entry prevention member 12. Send to -1. In the warehousing prevention device 10-1, upon acquiring the instruction to raise the warehousing prevention member 12 transmitted from the parking lot management device 60, the member operation mechanism 13 raises the warehousing prevention member 12. By raising the entry prevention member 12, other vehicles are prevented from entering the compartment B-1, and the compartment B-1 is secured for use by the user X.

[0034] The process executed by the parking lot management system 1 when the vehicle C of the user X who has made a reservation to use the parking lot P as described above arrives at the parking lot P will be described. When the vehicle C of the user X arrives at the parking lot, the vehicle identification information acquisition unit 32 of the vehicle information acquisition device 30 photographs the vehicle C, and acquires the vehicle number information of the license plate of the vehicle C by analyzing the photographed information. do. The vehicle identification information acquisition unit 32 transmits the acquired vehicle number information of the vehicle C to the parking lot management device 60.

[0035] FIG. 3 is a flowchart showing the flow of processing executed by the parking lot management device 60 when the vehicle number information of the vehicle C that has arrived at the parking lot P is acquired. When the parking lot management device 60 acquires the vehicle number information of the vehicle C from the vehicle information acquisition device 30 (“YES” in S1), the reservation information acquisition unit 644 acquires the vehicle number information based on the information stored in the reservation information storage unit 632. It is recognized that reserved vehicle C has arrived. The reservation information acquisition unit 644 acquires reservation information corresponding to the acquired vehicle number information from the reservation information storage unit 632 (S2).

[0036] At this time, the reservation information acquisition unit 644 determines that among the reservation information reserved for the vehicle with the vehicle number information, the reservation target date is the same day as the current one, and the time at which the usage time has elapsed from the reserved usage start time is the current one. Obtain reservation information that is later than the specified time. In other words, if vehicle C arrives before the reservation start time "15:00" on the reservation target date "2022 / 02 / 01", and from the reservation start time "15:00" If the vehicle C arrives by the time "17:00" when the reservation time "2 hours" has elapsed, it is determined that the reserved vehicle C has arrived, and the corresponding reservation information is acquired.

[0037] Next, the assigned cabin determining unit 645 acquires from the usage status acquiring unit 643 the usage status of the cabin B-1 indicated as a usage target in the reservation information acquired by the reservation information acquiring unit 644. Then, when the assigned compartment determining unit 645 determines that the corresponding compartment B-1 is vacant (“YES” in S3), it determines to allocate the corresponding compartment B-1 to the vehicle C (S4).

[0038] After determining the cabin B to be assigned to the vehicle C, the assigned cabin determining unit 645 generates notification information for notifying the user X of the determined cabin B, and transmits it to the guide information display device 40 (S5). . This notification information includes information for guiding the vehicle from the entrance E of the parking lot P to the assigned compartment B. The guide information display device 40 displays notification information transmitted from the parking lot management device 60. By visually recognizing the information displayed on the guide information display device 40, the user X recognizes the compartment B to be used, and moves the vehicle C to the corresponding compartment B according to the guidance to enter the vehicle.

[0039] Further, if the allocated vehicle room determining unit 645 determines that the vehicle room B-1 indicated as the target of use in the reservation information is being used by another user in step S3 (“NO” in S3), Based on the information acquired from the status acquisition unit 643, it is determined whether there is an empty cabin B (S6).

[0040] Here, when the allocated vehicle room determination unit 645 determines that there is an empty vehicle room B ("YES" in S6), the allocated vehicle room determination unit 645 selects the vehicle room with the highest preset priority from among the vacant vehicle rooms B. It is decided to allocate B to vehicle C (S7).

[0041] The priority of each cabin B used to determine which cabin to allocate to vehicle C from empty cabins B is set higher, for example, as the distance to entrance F to store ST is shorter. Further, the priority may be set higher as the distance from the vehicle C to the cabin B-1 indicated as a usage target in the reservation information is shorter. Further, the priority level may be set high for the vehicle compartment B in which the adjacent vehicle compartment is empty. Furthermore, based on the information stored in the reservation information storage unit 632, the less free time there is between the preceding and following time slots for the corresponding compartment, the higher the priority is set to increase the utilization efficiency of the parking lot P. good. Furthermore, at this point, if the cabin B reserved by another user has not been used even after a certain period of time has passed from the reservation start time, the allocated cabin determination unit 645 may determine that the use of the vehicle compartment B has been canceled without permission, include the vehicle compartment B in the allocation target, and set its priority as appropriate. Based on the priority set in this way, the assigned cabin determining unit 645 determines the cabin to be assigned to the vehicle C.

[0042] After determining the cabin B to be assigned to the vehicle C, the assigned cabin determining unit 645 generates notification information for notifying the user X of the determined cabin B, and transmits it to the guide information display device 40 (S8). . The guide information display device 40 displays notification information transmitted from the parking lot management device 60. By visually recognizing the information displayed on the guide information display device 40, the user X recognizes the compartment B to be used, and moves the vehicle C to the corresponding compartment B according to the guidance to enter the vehicle.

[0043] When the vehicle C enters the corresponding compartment B, the usage status acquisition unit 643 detects this (“YES” in S9) and cancels the reservation information regarding the user X in the reservation information storage unit 632 (S10). By canceling the reservation of user X, other users can immediately use cabin B-1 when it becomes vacant.

[0044] In step S6, if it is determined that there is no vacant cabin B (“NO” in S6), the allocated cabin determination unit 645 selects one spare cabin from among those stored in the spare cabin information storage unit 631. Obtain information, for example, information about spare compartment B-19. Based on the acquired information, the assigned cabin determining unit 645 determines to allocate the spare cabin B-19 to the vehicle C (S11). Here, the assigned vehicle room determining unit 645 may notify the manager of the parking lot P by outputting information from the output unit 65 to notify the manager of the determination. In addition, the assigned vehicle room determination unit 645 may distribute information such as a coupon that provides benefits such as discounts regarding the use of the parking lot P to the user terminal 50 in return for the assigned vehicle room becoming a spare vehicle room. good.

[0045] Also, here, the parking lot management device 60 sends information to the user terminal 50 to inquire whether to postpone the arrival time without using the spare compartment B-19 or to use the determined spare compartment B-19. , and when a response indicating that the spare compartment B-19 will be used is obtained, it may be decided to finally allocate the spare compartment B-19 to the vehicle C. In addition, if User It may be decided to assign room B-19 to vehicle C. By performing processing in this manner, the frequency of use of the spare compartment can be reduced as much as possible, and the probability that the spare compartment can be effectively used when an emergency situation occurs can be increased.

[0046] After determining the cabin B to be allocated to the vehicle C, the assigned cabin determining unit 645 moves to step S8.

[0047] According to the embodiment described above, the parking lot management device 60 specifies the vehicle to be used and specifies the vehicle to be used so that the user who has made a reservation for the use of the parking lot can surely use the parking lot. Room allocation processing can be executed. As a result, other users may be using the reserved cabin in a time slot earlier than the reserved time slot, and the other user's usage time may be longer than planned, or the reserved user may Even if the reserved car room is not available because the user arrives earlier than the reservation start time, the user who has made the reservation can surely use the parking lot.

[0048] In the embodiment described above, a case has been described in which the vehicle information acquisition device 30 acquires identification information of the vehicle by analyzing image information obtained by photographing the vehicle with a camera device and acquiring vehicle number information. It is not limited to this.
