Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and method applied to a system for managing reservations for parking lots, and more specifically, reservation management for parking lots for improving serviceability regarding reservations for parking lots. The present invention relates to a device and a reservation management method. In this specification, the entire parking facility including the parking space and the management department is referred to as a “parking lot”, and the individual parking spaces in the parking lot are referred to as “lots”.

[0002]

2. Description of the Related Art As a conventional parking lot reservation management method, there is a parking lot reservation service processing method in a telephone exchange office disclosed in Japanese Patent Publication No. 60-24515. The method disclosed here generally stores information on the availability of parking lots in the telephone exchange office, and when the telephone exchange office receives a reservation request from a person who is trying to reserve the parking lot, The content is to issue a reservation ticket to a person who intends to make a reservation according to the vacancy information of the parking lot and to issue a reservation ticket to the parking lot. This empty block information indicates the number of lots that are currently in use, the number of lots that have reservations, and the number of empty lots that do not correspond to any of these, and new reservations can be made only when there are empty lots. It is possible.

This method allows the user to make a reservation without knowing the telephone number of each parking lot, so that the user can use the parking lot with peace of mind, and at the same time, the reservation ticket and reservation reservation ticket can be used. Issuing is intended to eliminate reservation troubles. For this reason, the telephone exchange station is to be equipped with a parking lot vacancy information, and the telephone exchange station is provided with a reservation receiving device and a device for issuing a reservation ticket and a reservation ticket.

[0004]

However, this parking lot reservation service processing method has the following problems.
That is, in this method, if a user who does not use the parking lot immediately completes the reservation from the time of reservation, the next reservation for the lot can be made only after the user has entered and exited the vehicle. I can't.

For example, the present time (point of reservation) is n days at 12:
As 00, if the person who wishes to use the vehicle from 12:00 on the n + 1 day completes the reservation, the lot cannot be used until the vehicle leaves the parking lot. Then, for example, a person who wishes to use from 13:00 to 19:00 on the nth day will not be able to make a reservation for the lot, although it has no effect on the use of the parking lot by Party A. . And if there are no other lots that can be booked, B cannot eventually use the parking lot, and the occupancy rate of the parking lot will decrease. For this reason, there were restrictions on reservations, and there was a possibility that the parking reservation service could not be fully realized.

In this method, a parking lot which the user does not know may be assigned. In this case, it is expected that a user who is assigned to a parking lot that he does not know will search for the parking lot and go back and forth, which is rather difficult for the user to use.

Therefore, the present invention has been made to solve such problems and provide a reservation management device and a reservation management method for a parking lot that can be used by the user with peace of mind. Therefore, it is an object of the present invention to improve a reservation service property by responding to a user's reservation request as much as possible.

Reservation acceptance is judged for a lot that has a blank time longer than a predetermined time between the scheduled entry time and the planned usage time, and the lot is used even if there is a slight change in the vehicle entry / exit time. Not to affect.

(4) Further, according to the parking lot reservation management device of the present invention, the stored contents of the parking lot status storage means are investigated by the overstay vehicle detection means to discover the overstay vehicle. That is, it is investigated whether or not there are vehicles that have not left the train even after the scheduled departure time. When an overstay vehicle is discovered,
If there is a reservation already assigned to the lot, the reservation is changed to another lot that can be assigned by the excess handling means, and vehicle duplication is prevented. At this time, the user may be notified that the reserved lot has been changed.

(5) According to the parking lot reservation management method of the present invention, the parking lot status storage means stores the use situation and reservation situation of each lot in the parking lot, that is, the presence or absence of vehicles at present and the allocation of reservations. The presence / absence is stored, and when a reservation request is made to the user parking lot including the planned entry time and the planned usage time, the request content and the storage content of the parking lot status storage means are compared. Then, it is determined whether or not there is an overlap between the reserved entrance time and reserved use time of the reserved vehicle and the planned entrance time and planned use time related to the reservation request, and if there is no overlap, the reservation is executed. Thus a lot is reserved for the user who made the reservation request.

(6) Further, according to the parking lot reservation management method of the present invention, when the user who has completed the reservation desires to be guided to the parking lot when the navigation device is installed in the vehicle of the user.

Thus, even if there is a slight change in the entry and exit times of the vehicles, the vehicles do not overlap and the use of the lot is not affected.

(8) Further, according to the parking lot reservation management method of the present invention, it is confirmed based on the stored contents of the parking lot status storage means whether or not there is an overstaying vehicle that has not exited even after the scheduled departure time. To do. When an overstaying vehicle is found, if there is a reservation already assigned to that lot, the reservation is changed to another assignable lot, thereby preventing the vehicle from being duplicated.

[0024]

According to the present invention, when a reservation request is made, a reservation is executed for a lot that does not have the same usage time as a reserved vehicle. Therefore, the lot is effectively used to improve the operating rate of the parking lot. However, the serviceability of the parking lot reservation for the user can be improved. Also, when the reservation request is accepted and the reservation is completed, the user is requested to provide guidance assistance to the parking lot, so that the user can arrive without hesitation in a short time even if the user does not know the parking lot. You can
Furthermore, if it is predicted that the use of the lot will be hindered by vehicles that will not leave even after the scheduled departure time, the reservation already made for that lot will be changed to another lot, which will prevent the lot from being used. It can be prevented.

First, the data file of the management computer 1 will be described. The data files provided in the management computer 1 include lot files, current vehicle files, reserved vehicle files, status files,
There is.

[0033]

[Table 1]

The lot file shown in Table 1 is for the parking ridge 80.
The basic settings of each lot are stored. In the "lot number" column of Table 1, the numbers of all lots in the parking ridge 80 are recorded. In the "Vehicle type" column, the types of vehicles that can be parked in each lot are recorded. For example, in the 001th lot, only a light car can be parked because it is said to be "light". On the other hand, in lot No. 002, "general" means "ordinary vehicle", and therefore ordinary vehicles (including small vehicles) or light vehicles can be parked. The "lot number" and "vehicle type" data are fixed data and are not rewritten.

In the "Use" column, "OK" or "No"
Is recorded. “OK” means that the lot can be used for parking by general vehicles. On the other hand, “non” means that the lot cannot be parked for a general vehicle, for example, because it is exclusively for a monthly contract vehicle. Although this "use" data is rewritable, unlike the data such as the status file described later, it is normally operated without rewriting. That is, the data of this lot file is basically fixed data.

[0036]

[Table 2]

The current vehicle file shown in Table 2 records the data of the current vehicle, that is, the vehicle currently parked in the parking ridge 80. The data in the “Current vehicle pointer” column of Table 2 is the number assigned when the current vehicle enters. Here, there are two current vehicles, and there are XXX1 pointer and XXX.
This shows a state in which the 2nd pointer is allocated. Therefore, the pointers after XXX3 are not assigned yet. In the "rental tag" column, the charging tag of each current vehicle is one that is brought by the vehicle or rented at the tag machine 4 at the entrance (hereinafter,
This is a column for recording the distinction between "rental tags"). X
In the XX No. 1 pointer, this field is "No", which indicates that the tag is a charging tag brought by the vehicle. Meanwhile, XXX
The second pointer indicates “Lending”, indicating that the lending tag is used.

The number written on the license plate of each current vehicle is recorded in the "license plate" column. The data in this column is read from the charging tag in the case of a vehicle carrying a charging tag, and is read and recorded by the camera 11 at the entrance in the case of a vehicle not carrying the charging tag. In the "ID" column, the identification number of the charging tag of each current vehicle is recorded. Even in the case of a vehicle that uses a rental tag, the identification number of the rental tag is recorded. The vehicle type classification of each current vehicle is recorded in the “vehicle type” column.

The date and time when each current vehicle enters the field are recorded in the "entry record" column. In the field of "Scheduled to leave", the scheduled departure date and time of the vehicle that has been scheduled to leave at the time of reservation or entry are recorded. XXX No. 1 pointer records the scheduled departure date and time, but XX
In the X2 pointer, this field is blank, indicating that the vehicle is scheduled to leave. The “possible delay” column records the number of days or hours of possible delay for a vehicle that has announced that there is a possibility that it will be delayed from the scheduled departure time together with the scheduled departure. It is recorded that the pointer No. 1 of XXX can be delayed by 4 hours. The data of the current vehicle file is written in the file along with the allocation of the current vehicle pointer when the vehicle enters, and is erased when the vehicle exits.

[0040]

[Table 3]

The reserved vehicle file shown in Table 3 is for recording the data of reserved vehicles, that is, the vehicles of which reservations have been accepted by the management computer 1 (excluding those already entered). The data in the "Reserved car pointer" column of Table 3 is the number assigned when the reservation is accepted. Here, there are two reservations, and the YYY1 pointer and the YYY2 pointer are allocated. Therefore, the YYY3 and subsequent pointers have not been assigned yet.

The number written on the license plate of each reserved vehicle is recorded in the "license plate" column. The data in this column is declared and recorded at the time of booking. The identification number of the charging tag used by each reserved vehicle is recorded in the “ID” column. If a user who has previously issued a unique billing tag reserves a parking lot, this identification number is declared and recorded at the time of booking, and if a user who does not have a unique billing tag makes a reservation. This field is left blank. Also, "rental tag" like the current car file in Table 2
There is no column. In the "Vehicle type" column, the vehicle type classification of each reserved vehicle is recorded.

The date and time when each reserved vehicle is scheduled to enter is recorded in the "Entry Schedule" column. There are two scheduled entrance times, A and B, with a certain width in consideration of the fact that the actual arrival time of the vehicle fluctuates depending on the surrounding traffic conditions and the like. The date and time when each reserved vehicle is scheduled to leave the field is recorded in the column "Scheduled to leave". The “possible delay” column records the number of days or hours that the vehicle may be delayed from the scheduled departure time for the vehicle. It is recorded that the YYY1 pointer may be delayed for 5 days.

The data of the reserved car file is written in the file together with the allocation of the reserved car pointer at the time of reservation, is erased when the reserved car is entered, and is transferred to the current car file. Alternatively, if the reservation is canceled or there is no entry after the scheduled entry time B exceeds the predetermined time B, the entry is deleted without transfer to the current vehicle file.

[0045]

[Table 4]

The status file shown in Table 4 records the usage and reservation status of each lot for each lot.
The "lot number" in Table 4 is the same as the "lot number" in the lot file in Table 1 and is therefore fixed data. The “Current status” column indicates the current status of the vehicle in the lot.
That is, 001 lot and 002 lot are “present”, that is, the existence of the current vehicle is shown, and other lots are “absent”, that is, it is currently empty. In the “current vehicle pointer” column, the current vehicle pointer of the current vehicle file in Table 2 of the current vehicle of the lot is recorded. That is, 0
It is shown that the current vehicle in the 01st lot is the vehicle with the XXX1 pointer, and similarly, the current vehicle in the 002 lot is the vehicle with the XXX2 pointer.

In the "reserved car pointer" column, the reserved car pointer of the reserved car file shown in Table 3 relating to the reservation assigned to the lot is recorded. That is, the reservation of the YYY1 pointer is allocated to the 001th lot, and the reservation of the YYY2 pointer is allocated to the 003th lot.

The "reservability" column indicates whether or not a reservation can be assigned to the lot. In this case, the lots No. 002 and No. 005 are "not available", indicating that reservation allocation cannot be made. X for 002 lot
This is because there is a current vehicle of XX No. 2 pointer, and according to the current vehicle file of Table 2, the exit schedule of this current vehicle is unknown.
This is because the “use” column of the lot file in Table 1 is “Not” for the No. 005 lot, and the use of ordinary cars is not permitted.

On the other hand, lots 001, 003,
The lot No. 004 is “OK”, which means that reservation allocation is possible. There are current and reserved cars in 001 lot, and reserved cars in 003 lot.
Since the scheduled departure time for each of these is recorded,
This is because reservations can be assigned in non-overlapping time zones. Since the 004th lot is a completely vacant lot with no current car or reserved car, reservation allocation is, of course, possible. The data of this state file is changed with the change of the current vehicle file or the reserved vehicle file, except for the fixed data "lot number".

Next, the data files of the entrance terminal 3 and the exit terminal 13 will be described. These terminals have some of the data themselves in order to interact with entering and leaving cars as quickly as possible and prevent traffic jams at the entrance and exit.

[0051]

[Table 5]

The entry terminal file shown in Table 5 is intended for quick verification when a reserved vehicle comes in and allocation of lots when a vehicle without reservation comes in. Therefore, for each lot number, "vehicle type",
It has data on "current status", "whether allocation is possible", and "reserved vehicle". Of these, "Vehicle type" is the "Vehicle type" in the lot file in Table 1 and is fixed data. "Current status" is shown in Table 4
“Present status” of the status file of “No”, and is changed in accordance with the rewriting of Table 4.

"Allocation availability" is a field for immediately allocating lots without inquiring to the management computer 1 when a vehicle without reservation has entered, and only the lots in which this field is "acceptable" It is a lot that can be assigned to admission vehicles without reservation. In this column, the “Use” column of the lot file in Table 1 is “OK”, and only lots for which there is no current vehicle and no reservation is assigned are “OK”. The reason is that for an admission vehicle without reservation, it is necessary to allocate it to a completely vacant lot because the entry gate 5 is passed quickly and the exit schedule is not declared.

The "reserved vehicle" is a column for checking the vehicle immediately without entering the management computer 1 when the reserved vehicle enters, and the reserved vehicle is displayed in the column of the lot to which the reservation is assigned. The number described on the license plate and the identification number of the charging tag used by the reserved vehicle are recorded. In this column, the data related to the reservation in which the scheduled entrance time A approaches until a predetermined time (for example, 30 minutes) is transferred from the management computer 1 and written therein. Then, in Table 5, there is also a column of "entry record", in which data regarding the current vehicle is recorded.

[0055]

[Table 6]

The exit terminal file shown in Table 6 is intended for promptly performing operations such as billing when there is a leaving vehicle without inquiring to the management computer 1. Therefore, the data regarding the current vehicles are in lots. It is recorded for each. “Vehicle type” in Table 6 is the vehicle type classification of the current vehicle, and does not necessarily match the “vehicle type” in Table 1. This is because light cars may be parked in lots that can be parked up to ordinary cars. The "rental tag" column corresponds to the "rental tag" column of the current vehicle file in Table 2. Then, in the "entry record" column, the number written on the license plate of each current vehicle, the identification number of the charging tag, the date of entry and the time of entry are recorded.

Next, the entire usage system including users in such a parking lot will be described with reference to the conceptual diagram of FIG.
As described above, the parking lot management computer 1 is connected to the public line 30 and can communicate with the user. Also, the parking lot management computer 1 is a public line 30.
It is also possible to communicate with the financial institution 50 via the Internet and automatically charge the parking fee.

Then, the user can communicate with the management computer 1 in the parking lot from the inside of the vehicle by using the navigation device 37 mounted on the vehicle 34 and the mobile phone (may be a car phone, the same applies hereinafter) 38. For this purpose, the road traffic information system (hereinafter referred to as VICS) 3 is used to make a call from the public line 30 to the navigation device 37 of the vehicle 34.
2 is used, and the vehicle 34 is provided with a radio wave receiver 36 for receiving this. Here, the information that is transmitted from the VICS 32 and that can be received by the radio wave receiver 36 includes the position information of the parking lot, and is used when the navigation device 37 of the vehicle 34 is used to guide the parking lot.

Alternatively, it is possible to communicate with the management computer 1 in the parking lot using the telephone 43, the personal computer 44, and the fax 45 of the home 40 or the office 41. It goes without saying that the personal computer 44 must be connected to the public line 30 by personal computer communication or the like.

Here, the charging tag will be described. The billing tag is for the purpose of smoothly collecting the parking fee and collating the vehicle related to the reservation when the parking lot is reserved with the vehicle that actually entered the parking lot.
The C card is combined with the transmitter / receiver and the identification number is recorded on it. The billing tag is issued to the user in advance by a prepaid method or a direct debit method.
In the case of the direct debit method, a cash card of a financial institution or a credit card of a credit institution can be used as this magnetic card or IC card. In addition, the charging tag is provided with a storage area for recording the lot number and the date and time of entry when passing through the entrance gate 5.

In order to make it available to users who have not been issued a billing tag, the parking lot is provided with a lending tag and is rented when an entrance vehicle without a billing tag passes through the entrance gate 5. I am trying to do it. When a user who makes a reservation without a billing tag enters the vehicle, the vehicle is checked by reading the license plate with the camera 11 at the entrance and identifying the written number.

Next, the operation will be described. In this parking lot,
The latest parking status is transmitted via the public line 30 at any time. This is so that the user can grasp the state of the parking lot and decide whether to go to the parking lot or to make a reservation. Specifically, the management computer 1 judges from the status file (Table 4) whether or not the parking lot is full, and sends the judgment result. In this case, considering that it takes a certain amount of time for the user to actually arrive at the parking lot after receiving this information, whether or not the vehicle is fully occupied considering the reservation situation about 30 minutes to 1 hour ahead. It may be determined whether or not. Then, in addition to this information, the telephone number of the parking lot is transmitted. This is so that the user can make a reservation without remembering the telephone number.

This information is transmitted via the public line 30 and is also transmitted from the VICS 32. Therefore, the user can receive this information in the vehicle by using the navigation device 37 or the mobile phone 38 mounted on the vehicle 34, and also by the telephone 43 of the home 40 or the office 41, the personal computer 44, and the fax 45. Information can also be received. Then, the management computer 1 updates the transmission contents at a short time interval of about 5 to 10 minutes in order to constantly provide the latest information.

Next, the reservation taking by the user will be described with reference to the flowchart of FIG. This flow is from the inside of the vehicle to the navigation device 37 and the mobile phone 38.
Shows the case of making a reservation using. First, in S1, a normal screen (map, etc.) is displayed on the navigation device 37. In this state, various optional functions can be selected, and parking lot information is one of the optional functions. When the occupant selects the parking information (S
2: Yes), the parking lot information is displayed on the navigation device 37, and at the same time the contents are transmitted by voice (S).
3).

The parking lot information displayed at this time is shown in FIG.
As shown in the example, the parking lot name, usage status, telephone number, number of reserved vehicles, and position code are included. As the usage status, the availability, the number of used lots, and the total number of lots are displayed. The position code is a code for searching the position of the parking lot and is used when guiding the vehicle to the parking lot, which will be described later. This information is the latest parking state information transmitted from the parking lot management computer 1, that is, transmitted from the public line 30 by the VICS 32 and received by the radio wave receiver 36 of the vehicle 34.

Then, the occupant who has confirmed the displayed information determines whether or not to make a reservation (S4). For example, when it is determined that the parking lot is very small and it is not necessary to make a reservation (S4: No), the navigation device 37
Returns to the normal screen (S1). When the occupant determines to make a reservation and gives an instruction to that effect (S4: Yes), the navigation device 37 operates the mobile phone 38 to call the management computer 1 in the parking lot. The telephone number at this time is V
It is included in the information provided by the ICS 32 and displayed in S2. Then, when it becomes possible to connect to and interact with the management computer 1, a reservation screen is displayed on the navigation device 37 (S5).

This reservation screen is shown in FIG. On this screen, "arriving at parking lot", "number plate",
"ID (billing tag identification number)" and "vehicle type" are automatically displayed. The "parking lot arrival schedule" is that the navigation device 37 automatically calculates the required time with a predetermined width based on the current position of the vehicle and the position of the parking lot, and adds the calculated time to the current time for display. The reason why the required time is wide is that it varies depending on traffic conditions.
The “license plate”, “ID”, and “vehicle type” are registered in the navigation device 37 in advance. However, if the vehicle does not have a billing tag, the "ID" column is blank.
Blank data is displayed for "Scheduled parking lot exit" and "Potential use extension". Not only is the contents of this screen displayed, but it is also conveyed by voice.

Then, the occupant inputs data requesting a reservation (S6). If there is no need to change the items of “parking lot arrival schedule”, “number plate”, “ID”, and “vehicle type” that are automatically displayed in S5, there is no need to input them. In addition, "parking lot leaving schedule" and "possibility of extension of use"
If you are unsure about, you can leave it blank. In this case, the planned use time of the parking lot is treated as infinite. When the input is completed (S7: Yes), it communicates with the management computer 1 and inquires as to whether or not it is possible to make a reservation with the requested content (S8). At this time, the management computer 1 compares the requested contents with the contents of the status file (Table 4) to judge whether the allocation is possible and returns the result. The details will be described later.

If the result of the inquiry is bad (S9: No), the navigation device 37 inquires the occupant whether to make an inquiry again by displaying and voice (S10). To re-enter (S10: Ye
s), the process returns to S6 to input another request content and inquire again. To give up the reservation (S10:
No), the screen returns to the normal screen display state of S1.

When the result of the inquiry is good in S9 (S9: Yes), the navigation device 37 inquires the passenger whether or not he / she wants to be guided to the parking lot by displaying and voice (S11). . If guidance is desired (S11: Yes), the navigation device 37 shifts to the guidance mode and shows the driver the route to the parking lot. That is, in this guidance mode, a map including the current position of the vehicle 34 is displayed on the navigation device 37, and the route to the parking lot is shown in consideration of traffic conditions such as road congestion. Therefore, it is possible to go to the parking lot by relying on this. Vehicle 3
As 4 approaches the car park, a more detailed map is displayed showing the best directions to the car park entrance.

The guidance to the parking lot is usually made by searching the parking lot position code (FIG. 5) provided by the VICS 32, but when the parking lot position code is not transmitted from the VICS 32, navigation is performed. Device 3
It is also possible to associate the telephone number of the parking lot with the map memory stored in 7, and search and guide the position by the telephone number of the reserved parking lot.

When the guidance is not desired (S11: N
o), the navigation device 37 returns to the normal screen. However, unlike the normal state of S1, a guidance function is added to the optional functions, and when guidance is required, this can be selected at any time.

In this flow, the case of making a reservation from the car using the navigation device 37 and the mobile phone 38 has been described, but the basic procedure is also the case when making a reservation using the telephone 43 of the home 40 or office 41, the personal computer 44, and the fax 45. It is the same. However, in that case, "arriving at the parking lot",
The items such as "license plate", "ID", and "vehicle type" are not automatically input, so the user needs to input them. Even if the reservation is accepted (S9: Y
es), it is not possible to immediately select the guidance mode, and if necessary, get on the vehicle 34 and then the navigation device 37.
Will select the guidance mode.

Next, reservation allocation in the management computer 1 will be described with reference to the flowchart of FIG.
When the user makes a reservation request (S21: Yes), the management computer 1 starts the work of reservation allocation. FIG. 4
This corresponds to S4: Yes in the flow of. And
By the inquiry communication of S8 in the flow of FIG. 4, the management computer 1 receives the request data (S22). The content of the request data to be received is shown in the screen of FIG.
It includes at least the scheduled arrival date and time, the narber plate, and the scheduled departure date and time, and may further include the ID and the possibility of extension of use.

Then, the management computer 1 compares the received request data with the "reservation allowance" column of the status file (Table 4) and the "vehicle type" column of the lot file (Table 1) to determine whether allocation is possible or not. A judgment is made (S23). That is, it is a lot that can park the requested vehicle type (vehicle type in Table 1),
In addition, it is determined whether or not there is a lot whose reservation availability in Table 4 is “OK” (hereinafter referred to as “target lot”). However, since the "reservation availability" column of the status file referred to here is displayed as "OK" except for the lots (002 and 005) that are completely blocked, it is judged as Yes here. However, it may not be possible to make a reservation in the end. When there is no target lot (S23: No), the process proceeds to S31 described later.

When there is a target lot (S23: Ye
s), it is determined whether or not the lot can be assigned to the target lot and the current vehicle is present (S24). That is, for a lot that is “OK” and has data in the “Current vehicle pointer” column of the status file (Table 4), the request data of S22 is set to “Exit schedule” of the current vehicle pointer of the current vehicle file (Table 2). And "possibility of delay" to determine whether there is overlap time. If not only the current vehicle but also a reserved vehicle is already allocated to the lot, the allocation availability is determined by also referring to the data of the reserved vehicle file (Table 3) for the reserved vehicle pointer.

It should be noted that the current vehicle to be judged here is limited to one that has been reserved and entered. If you enter without a reservation, you will not be notified of the exit schedule as described below, so the lots of vehicles that entered without a reservation will always have a "No" in the "Reservability" column.
This is because the target lot cannot be the target lot.

When the allocation to the target lot with the current vehicle cannot be performed (S24: No), it is determined whether or not the allocation to the target lot to which the reserved vehicle is already allocated although there is no current vehicle (S25). That is, for a lot that is a target lot and has no data in the “current vehicle pointer” column of the status file and has data in the “reserved vehicle pointer” column, S22
Of the requesting vehicle pointer of the reserved vehicle file in the reserved vehicle file is compared with "entry schedule", "leaving schedule" and "possibility of delay" to determine whether there is an overlap time.

When the target lot with the current vehicle can be assigned (S24: Yes) or when the target lot with the reserved vehicle but no current vehicle can be assigned (S25: Yes)
For the target lot that can be allocated, it is determined whether or not there is a problem in allocation even if safety is expected (S26). This is because the departure of the vehicle may be delayed from the scheduled time. Specifically, for the current vehicle, the reserved vehicle already allocated, and all of the requested data,
A safety margin (for example, 3) set in advance at the scheduled departure time (including the possibility that it will be delayed)
0 minutes) is added, and it is judged to be safe only when there is no overlap time.

If it is safe (S26: Yes),
It proceeds to S29 described below. If it is not safe (S26:
No), the process returns to S23, and the same determination is made for the remaining target lots. The determinations in S24, S25 and S26 are
By allocating a new reservation as much as possible to the existing vehicle or a lot with a reserved vehicle, the purpose is to leave a completely vacant lot as much as possible. This is to facilitate handling of vehicles whose departure schedule is unknown (entrance vehicles without reservations and reservation requests without declaration of departure schedules).

In S25, when there is no current vehicle but a reserved vehicle cannot be assigned to the target lot (S25: No),
Proceed to S27. In this case, there is no current vehicle or reserved vehicle that has already been allocated, that is, there is a selection branch only for completely empty lots, so it is determined in S27 whether or not there are completely empty lots. In the judgment of S23, even if there is no completely vacant lot, it can be judged as Yes, so that the judgment is required again here. If there is no completely vacant lot in S27 (S27: No), the reservation request cannot be accepted in the end though it is determined as Yes in S23, and the process proceeds to S31.

If there is a completely vacant lot (S2
7: Yes), if there is no problem in the allocation, the entrance terminal 3
(S28). The entrance terminal 3 has an entrance terminal file (Table 5) in order to prevent entrance congestion, and when there is a reservation-free entry car, it is immediately assigned to a completely vacant lot. This is to prevent double allocation because the data in the state file (Table 4) may not be modified yet and may occur. If the response from the input terminal 3 is bad (S
28: No), and returns to S27 to determine whether or not a completely vacant lot remains. When the response from the input terminal 3 is good (S28: Yes), the process proceeds to S29.

S29 (S26: Yes or S28: Ye
In s), the reservation request is executed. That is, the requested data is recorded in the reserved car file (Table 3). Specifically, the scheduled arrival date in the screen of FIG. 6 is recorded in “Date of entry” in the “Date” field, and the earliest scheduled arrival time (left side in FIG. 6) is designated as “Time A”. Record and record the later one (right side in FIG. 6) at “time B”. And the license plate, I
Record D and vehicle type in the corresponding columns. Furthermore, if the exit schedule is entered, the data will be recorded in the "Exit Schedule" field, and if the extension possibility is entered, the data will be recorded in the "Potential delay" field. .

Then, a reserved vehicle pointer is added to the recorded data, and the reserved vehicle pointer is recorded in the "reserved vehicle pointer" column of the assigned lot in the status file (Table 4). Further, the input terminal 3 is instructed to change the "Allocation availability" column of the lot in the entry terminal file (Table 5) to "not". If the "scheduled entry time A" of the data is within the predetermined time (for example, 30 minutes) preset from the current time, enter the license plate and ID (leave blank if blank) in the "Reserved car" column. Record. When the user is notified that the reservation has been accepted (S30), the process ends.

Then, S31 (S23: No or S27:
In No, the user is informed that the reservation request cannot be accepted. Then, it is determined whether or not there is another request from the user (S32). When there is a re-request (S32: Yes, corresponding to S8 after S10: Yes in the flow of FIG. 4), the process returns to S23 and the same judgment is repeated for the data relating to the re-request. If there is no request again (S
32: No, corresponding to S10: No in the flow of FIG. 4), the process ends. In addition, in the reply of S31, you may also introduce other parking lots.

Here, the processing when a vehicle enters or leaves the parking lot will be described. First, a case where there is a vehicle entering the entrance path 82 will be described. When the start sensor 9 detects the entry of the vehicle, the antenna 10 and the camera 11 are activated. The antenna 10 communicates with the billing tag, and the camera 1
1 identifies the vehicle type by reading the number plate of the approaching vehicle. As a result, it is determined whether or not the approaching vehicle has a billing tag, and if it has a billing tag, it is determined from the data whether it is a reserved vehicle or not. If the vehicle does not have a billing tag, the number plate read by the camera 11 is used to determine whether or not the vehicle is a reserved vehicle.

If the vehicle is a reserved vehicle as a result of comparison with the "reserved vehicle" column in the entrance terminal file (Table 5), entrance gate 5
And the admission of the reserved car is transmitted to the management computer 1. Then, the "Current status" column of the entrance terminal file is set to "Yes", the "Reserved car" column is deleted, and the "Admission record"
The entry vehicle data is recorded in the column. Further, when the reserved vehicle has a charging tag, the entrance date and time is recorded in the charging tag of the vehicle by the antenna 10, and when there is no charging tag, the tag machine 4 records the entrance date and time in the rental tag and lends it. The identification number of the rental tag is recorded in the "ID" column.

On the other hand, the management computer 1 retrieves the reserved vehicle file (Table 3) and the status file (Table 4) and displays the lot number of the corresponding reserved vehicle on the displays 7, 22. Then, the data of the corresponding reserved vehicle pointer in the reserved vehicle file is deleted, and instead, the data of the entering vehicle is recorded in the current vehicle file (Table 2) and the current vehicle pointer is added. The state file will be rewritten accordingly. Further, the entry vehicle data is also sent to the exit terminal 13, and the data is recorded in the corresponding lot number in the exit terminal file (Table 6).

When the approaching vehicle is not a reserved vehicle, the entrance terminal 3 allocates a lot whose “Allocation availability” column in the entrance terminal file (Table 5) is “OK” in consideration of the vehicle type of the approaching vehicle. Here, in order to prevent entrance congestion, the entrance terminal 3 makes its own allocation without inquiring of the management computer 1. However, if there is another car that has just entered, the lot that is far from the lot of the car that just entered and that can be reached without passing in front of that lot is given priority. This is to prevent traffic jams in the venue, because it is possible that the last-time entry car was turning around to enter its lot. Also, in order to prevent traffic congestion at the entrance, we will not make inquiries about leaving. This is to allow the entrance to pass through as quickly as possible.

In the case of a car with a charging tag, antenna 1
The entry date and time is recorded in the billing tag by 0, and in the case of a vehicle having no billing tag, the entry date and time is recorded in the lending tag by the tag machine 4 and rented. Then, the entrance gate 5 is opened and the assigned lot numbers are displayed on the display devices 7 and 22. Further, the “present status” column of the entrance terminal file is set to “present”, the “assignment availability” column is set to “not”, the entry vehicle data is recorded in the “entry record” column, and the data is transmitted to the management computer 1. .

Therefore, the management computer 1 records the entry vehicle data in the current vehicle file (Table 2), attaches the current vehicle pointer, and rewrites the state file accordingly.
The exit terminal 13 is also instructed to record the data in the exit terminal file. When the entrance vehicle passes through the end sensor 12, the operation of the antenna 10 and the camera 11 is stopped, and the entrance gate 5 is closed after a lapse of a predetermined time.

Next, the case where there is a vehicle leaving the exit route 83 will be described. When the start sensor 18 detects an exiting vehicle, the antenna 19 is activated, communicates with the billing tag, and refers to the exit terminal file to determine which lot the vehicle is from. If the reading of the billing tag fails, the camera 20 reads the number plate of the leaving vehicle to identify the vehicle.

Then, the parking fee is displayed on the display unit 16, and if the charging tag of the vehicle is of the direct debit system of bringing the vehicle, the usage record is recorded on the charging tag by the antenna 19 and the exit gate 15 is opened. . When the charging tag of the vehicle is of a prepaid type brought by the vehicle, the parking fee is deducted from the balance by the antenna 19 and the exit gate 15 is opened. If the balance is insufficient, the tag machine 14 collects the difference and then the exit gate 15 is opened. If the billing tag of the vehicle is a rental tag, a message indicating that it should be returned is displayed on the display unit 16 together with the parking fee, and the tag unit 14 collects the rental tag and collects the fee and then exit gate. Open 15

Then, the data of the corresponding lot number in the exit terminal file is erased, and the fact that the vehicle has exited is transmitted to the management computer 1. Therefore, the management computer 1
Then, in the status file (Table 4), set the "Current status" column of the relevant lot number to "None", delete the "Current vehicle pointer" field, and "Yes" if the "Reservation availability" field is "No". And The current vehicle pointer data corresponding to the current vehicle file (Table 2) is also deleted. Further, the entrance terminal 3 is also instructed to set the "current status" column to "absent" for the corresponding lot number in the entrance terminal file (Table 5), and erase the data in the "entry record" column. If there is no subsequent reservation allocation for the lot, the “Allocation availability” column is set to “OK”.

This parking lot manages reservations and entrances and exits as described above, but since vehicles may not enter and exit on schedule, check this regularly (eg, every 5 minutes). ing. First, if there is a reservation but there is no entry for the reserved car (hereinafter referred to as "missing")
Will be described. The management computer 1 checks the reserved vehicle file (Table 3), and if there is a reserved vehicle pointer that has not passed the “time B” of “planned entry” but has not been deleted, it is determined to be absent. In this case, the reservation is regarded as canceled, the data of the reserved car pointer in the reserved car file is erased, and necessary data is rewritten in the status file (Table 4) and the entrance terminal file (Table 5). . This is to prevent a lot of meaningless occupation.

Next, a case will be described in which, although the current vehicle is scheduled to leave, the vehicle does not leave even after the scheduled departure time (hereinafter referred to as “excess”). The management computer 1 checks the current vehicle file (Table 2), and it is deleted even if the "time to leave""time" (however, if there is data of "possibility to be delayed" is added), it is deleted. If there is not the current car pointer, it is judged as excess.
The management computer 1 allocates the reservation request in consideration of the entry / exit schedule of the current vehicle or the reserved vehicle (S24 and S2 in FIG. 7).
5) In consideration of further safety (S26 of the same), duplicate cars are prevented, but if there is an excess, there is a risk of duplicates, so there is a possibility of duplication by changing the allocation for reservations already assigned lots. Eliminate. This processing will be described with reference to the flowchart of FIG.

When an excess vehicle is found (S41: Y
es), a process of prohibiting the subsequent reservation allocation to the lot is performed (S42). In other words, regarding the current vehicle pointer of the current vehicle file, "exit scheduled" and "possibility of delay"
The data of No. is deleted, and the column of "possibility of reservation" of the lot number in the status file (Table 4) is set to "not". Then, it is determined from the "reserved car pointer" column of the status file whether or not there is a reservation already assigned to the lot. If no reservation is assigned to the lot (S4
3: No), since there is no further problem, the process ends. If a reservation is assigned to that lot (S4
3: Yes), since there is a possibility of duplication if left unattended, the allocation is changed (S44).

Specifically, if there is another lot to which the reservation can be assigned, the assignment is shifted to that lot. This avoids duplication. If there is no lot that can be assigned,
Duplication cannot be avoided until the excess vehicle or other current vehicles that are not scheduled to leave, but it is resolved before the duplication actually occurs by changing the allocation so that the time zone where duplication may occur is postponed as much as possible. To do so.

As described in detail above, in this parking lot, the management computer 1 is provided with a status file (Table 4) for recording the usage status and reservation status for each lot of the parking ridge 80, and Since the information on the availability of the vehicle is always transmitted through the public line 30, the person using the parking lot can use the telephone 43 of the home 40 or the office 41 and the personal computer 4
4, the fax 45 or the mobile phone 38 can be used to receive this information at any time, and the information on the fullness of the parking lot can be known. Since this information is also transmitted from the VICS 32, it can be received in the vehicle by using the navigation device 37 mounted on the vehicle 34. Therefore, the user who receives this information and knows the information about the fullness of the parking lot can decide whether or not to head to the parking lot and make a reservation.

The management computer 1 is connected to the public line 3
0 and VICS 32 are connected, the user can make a reservation request by communicating with the management computer 1 using each of the above devices. Further, since the information provided from the management computer 1 includes the telephone number of the parking lot, the user can make a reservation request without knowing the telephone number in advance, especially when making a reservation from the car. The mobile device 38 can be operated by the navigation device 37 to connect to the management computer 1. Further, since the scheduled entry time is included in the content of the reservation request, it is possible to make a reservation even when the user is not going to the parking lot immediately.

Then, if the reserved user wishes, the navigation device 37 indicates the route to the parking lot and the vehicle 3
Since 4 is guided to the parking lot, even a user who does not know the position of the parking lot can make a reservation and can use the parking lot with peace of mind. Further, the use of the navigation device 37 can be expanded to promote its use.

Since the management computer 1 is provided with a status file, a reserved vehicle file (Table 3), etc., the contents of the reservation request are compared with these to judge whether the reservation request can be accepted, The reservation can be executed only when possible. In addition, since the lot is a current car or a reserved car and has a predetermined margin time between the planned stay time and the planned stay time related to the reservation request, the reservation is preferentially assigned to the lot. , It is possible to handle a vehicle that enters without reservation by leaving a completely empty lot as much as possible without any current vehicle or reserved vehicle.
Also, when assigning a reservation to a completely vacant lot, the entrance terminal 3 is made to confirm, so even if there is a reservation request immediately after a vehicle without reservation enters, double allocation is prevented and No entry vehicles can pass through the entrance quickly.

Furthermore, since the current vehicle file (Table 2) is regularly checked by the management computer 1, it is possible to find an excess vehicle that has not left the vehicle even after the scheduled departure time B. If so, subsequent allocation of reservations to the lot is prohibited, and if there is a reservation already allocated to the lot, the allocation can be changed to prevent vehicle duplication.

Although the present invention has been described with reference to the embodiments, the present invention is not limited to the above embodiments, and it goes without saying that various improvements and modifications can be made without departing from the spirit of the invention. For example, although the system for managing one parking lot is described in the above embodiment, a plurality of parking lots may be managed collectively by the same method. Further, in addition to the reservation management of the parking lot, a function of guiding the entry / exit vehicles in the hall may be added. Alternatively, the latest availability information of the parking lot is transmitted through the public line 30, but if the use of radio waves in the radio band or light band is permitted, the user can use the radio band to use the radio receiver. Information may be received.
