Description

  The present invention relates to an information processing device, an information processing system, an information processing method, and a program, and more particularly, to an information processing device, an information processing system, an information processing method, and a program that prompt an unoccupied person to board at an appropriate time.

  In airports, passengers may not appear at the boarding gate even when the final guidance is about to leave. In such a case, for example, a staff member who works at the airport can search around the airport by hand, or use the in-house broadcasting facility in the airport to broadcast to the non-boarders to the boarding gate. By using, the boarding of non-passengers is encouraged.

  However, the method of searching around by human power and calling by broadcasting as described above is a method lacking certainty. For this reason, there are cases in which an unoccupied person cannot be boarded on an airplane because the unoccupied person could not be found. Therefore, in order to cope with such a problem, a technique for grasping a place where a passenger is present by using a boarding pass of a passenger aircraft equipped with an RFID tag is known.

  For example, Patent Documents 1 and 2 are known as techniques for identifying the location of an unoccupied person using such an RFID tag. Japanese Patent Application Laid-Open No. 2004-133867 discloses a technique for efficiently searching for a non-passenger by using a movable RFID reader in a system that uses an RFID tag to identify the location of a non-passenger. Is described.

  Patent Document 2 describes a technique in which a processing device searches for an unoccupied passenger when a predetermined time before the departure time. In this technique, a search for unoccupied persons is performed by the processing device a predetermined time before the departure time. When a non-passenger is searched, for example, the location of the non-passenger is determined from the latest RFID reader installation position (the most recent non-passenger was detected), or an alarm is given to the non-passenger. Warning.

JP 2005-267613 A JP 2008-181301 A

  However, with the technique of Patent Document 1, only the position information of the passenger can be known. Therefore, it is left to the person to decide whether or not an unoccupied person is in time for boarding. As a result, there has been a problem that the search for unoccupied passengers is not always started at an appropriate time.

  Further, in the technique of Patent Document 2, for example, the degree of congestion at an airport is not considered. Therefore, depending on the congestion situation in the airport building, it may be difficult for an unoccupied person to reach the boarding gate by the departure time even if a warning is given before a predetermined time. Thus, even if the technique of Patent Document 2 is used, there is a problem that the search for an unoccupied person is not always started at an appropriate time.

  As described above, there is a problem that even if the location of the passenger is grasped using the RFID tag, it is not possible to search and warn a non-passenger at an appropriate time.

  In the first embodiment of the present invention, a boarding guidance system 1 that grasps a passenger's whereabouts (current location) at an airport or the like and issues a predetermined warning at an appropriate time calculated from the boarding time and the passenger's whereabouts, etc. An information processing system will be described. As shown in FIG. 1, at a general airport, a passenger first checks in at a check-in counter. The checked-in passenger deposits his / her baggage at the baggage check-in counter, passes through the security check, and boardes from the boarding gate (after immigration check for international flights). Here, for example, as shown in FIG. 2, in a security checkpoint or the like, a queue for security check is generated, and it may take time to pass the security checkpoint. Further, as shown in FIG. 3, for example, a passenger may do shopping or a meal at a store such as a duty-free shop or a restaurant, and may not go straight to the boarding gate. Therefore, the boarding guidance system 1 according to the present embodiment calculates the time required from the current location of the passenger to the boarding gate in consideration of the various situations as described above. Then, the boarding guidance system 1 gives a predetermined warning at an appropriate time calculated based on the calculated required time.

(Constitution)
As shown in FIG. 4, the boarding guidance system 1 in this embodiment includes a check-in counter 2, a plurality of RFID readers 3 (a wireless IC tag reader, a part of wireless IC tag position information acquisition means), and a tag management device 4. (Part of the wireless IC tag position information acquisition means), a plurality of queue monitoring cameras 5 (movement inhibition factor detection means, detection device), and a delay detection device 6 (part of required time calculation means, warning means) , A warning notification unit 7 (warning means) and a boarding pass 8 (wireless IC tag). Further, the check-in counter 2 and each of the plurality of RFID readers 3 and the tag management device 4 are connected so as to be communicable, and the tag management device 4 and each of the plurality of queue monitoring cameras 5 and the delay detection device 6 are connected. Are connected so that they can communicate with each other. Furthermore, the late arrival detection device 6 and the warning notification unit 7 are connected so as to communicate with each other.

  Here, as shown in FIG. 5, for example, the plurality of RFID readers 3 are installed in various stores for eating and shopping, baggage check counters, airport facilities such as security inspections, and the like. The plurality of queue monitoring cameras 5 are installed at a place where a queue is considered to occur, for example, at a baggage check counter or a security checkpoint. By installing the RFID reader 3 and the queue measuring device 5 in this way, the current location of the passenger is grasped, and the required time from the grasped current location to the boarding gate is calculated. Details of each component will be described below.

  The check-in counter 2 includes a check-in terminal 21 and an RFID writer 22.

  The check-in terminal 21 is a general terminal that collates the reservation information of the passenger with the ticket brought by the passenger, or designates the seat of the aircraft to be boarded. The check-in terminal 21 issues a boarding pass 8 to which the RFID tag 81 is attached in response to a series of check-in operations by inquiring with reservation information, specifying a seat, and the like.

  The RFID writer 22 writes a unique ID (identification information) assigned in the tag management device 4 to be described later to the RFID tag 81. As will be described later, the unique ID written by the RFID writer 22 is associated with the boarding flight name of the passenger, emergency contact information, and the like in the tag management device 4. Note that the RFID writer 22 may be configured to write passenger information such as boarding flight name information and seat information of the passenger in the RFID tag 81 together with identification information. Further, the RFID writer 22 may be configured to write a warning time (to be described later, for example, a boarding time of an aircraft on which a passenger is scheduled to ride) in the RFID tag 81.

  As described above, when the passenger checks in, the check-in counter 2 writes the identification information to the RFID tag 81 and issues the boarding pass 8 including the RFID tag 81 in which the identification information is stored. Therefore, the passenger who has received the boarding pass 8 that stores the identification information holds the boarding pass 8 that stores the identification information and travels from the check-in counter to the boarding gate.

  The RFID reader 3 reads the identification information (unique ID) written on the RFID tag 81 in a non-contact manner by wireless communication when the RFID tag 81 (the boarding pass 8 to which the RFID tag 81 is attached) passes nearby. Then, the RFID reader 3 transmits the read identification information and RFID reader information to the tag management device 4. Here, the RFID reader information is information stored in advance in each RFID reader 3 and is information for identifying the RFID reader 3 determined for each RFID reader 3. The RFID reader 3 transmits identification information and RFID reader information to the tag management device 4, so that the tag management device 4 can grasp which identification information is acquired by which RFID reader 3. In addition, when the passenger's boarding flight name information, seat information, warning time, and the like are described in the RFID tag 81, the RFID reader 3 reads out the various information as well as the identification information. Then, the RFID reader 3 transmits the above various information together with the identification information to the tag management device 4.

  As described above, the RFID reader 3 is installed in various places in the airport. Specifically, for example, RFID readers 3 are installed in places such as baggage inspection counters, security checkpoints, immigration checkpoints, and other places where passengers pass, as well as various facilities such as stores, customs, and toilets in the airport building (see FIG. 5). Note that the number and location of the RFID readers 3 may be appropriately changed according to the scale of the airport.

  By installing the RFID reader 3 in various places in the airport in this way, when a passenger holding the boarding pass 8 passes near the RFID reader 3 installed in various places in the airport, the RFID reader in the vicinity of the passenger 3 reads the identification information stored in the boarding pass 8. Then, the RFID reader 3 that has read the identification information transmits the read identification information and its own RFID reader information to the tag management device 4. By such an operation, identification information of the boarding pass 8 that has passed near the RFID reader 3 is transmitted to the tag management device 4 from the RFID reader 3 installed at various places. As will be described later, the tag management device 4 uses the identification information transmitted from the RFID reader 3 and the RFID reader information to grasp the approximate current location of each boarding pass 8 (the passenger who holds the boarding pass). .

  The RFID reader 3 uses RFID reader position information (position information of the wireless IC tag reader) indicating the position where the RFID reader 3 is installed together with the RFID reader information (or instead of the RFID reader information) as the tag management device 4. You may comprise so that it may transmit to. In this case, the tag management device 4 described later may not include the RFID reader position information storage unit 44.

  Further, when reading the identification information, the RFID reader 3 can be configured to acquire an identification information acquisition time which is a time when the identification information is read. When the RFID reader 3 is configured to acquire the identification information acquisition time, when the RFID reader 3 transmits the identification information and the RFID reader information to the tag management device 4, the identification information acquisition time is not limited to the tag management device. 4 will be transmitted.

  The tag management device 4 is an information processing device that includes an arithmetic device and a storage device. The tag management device 4 realizes each function to be described later when the arithmetic device executes a program stored in the storage device.

  As shown in FIG. 6, the tag management device 4 executes a program stored in the storage device, whereby an identification information allocation unit 41, an identification information / passenger information storage unit 42, and an RFID reader information / identification information receiving unit 43, an RFID reader position information storage unit 44, an RFID tag position information acquisition unit 45 (wireless IC tag position information acquisition means), and a point passage information storage unit 46 are realized.

  The identification information assigning unit 41 assigns a unique ID (identification information) to be written on the RFID tag for each RFID tag (boarding pass 8). As described above, the identification information assigned by the identification information assigning unit 41 is transmitted to the check-in counter 22 and written to the boarding pass 8 (internal RFID tag) by the RFID writer 22.

  Moreover, the identification information allocation part 41 is the identification information allocated for every RFID tag 81 (boarding pass 8), and the passenger information which is the information of the passenger who will hold the boarding pass 8 assigned the identification information. Are stored in the identification information / passenger information storage unit 42 in association with each other. Here, the passenger information indicates, for example, boarding flight name information indicating boarding flight names that can be boarded by the boarding pass 8, boarding time information showing boarding time, and emergency contact information of passengers boarding on the boarding pass 8. It is emergency contact information. As the passenger information, for example, information stored in a passenger information storage unit (not shown) is used or acquired from the outside.

  The identification information allocating unit 41 can be configured to transmit the passenger information and the warning time to the check-in counter 22 together with the identification information. Here, the warning time is a reference time for determining whether or not to issue a warning compared to the required time, as will be described later, for example, a time set as the boarding time. The warning time may be set to be a predetermined time earlier than the boarding time, for example, 10 minutes before the boarding time. As described above, the identification information allocating unit 41 transmits the passenger information and the warning time together with the identification information to the check-in counter 22, so that the RFID writer 22 of the check-in counter 22 stores the passenger information and the RFID tag 81. The warning time is written together with the identification information.

  As described above, the identification information / passenger information storage unit 42 stores the identification information assigned by the identification information assignment unit 41 and the corresponding passenger information in association with each other. The passenger information such as the emergency contact information stored in the identification information / passenger information storage unit 42 in association with the identification information is used, for example, when a warning is given by the warning notification unit 7. The identification information / passenger information storage unit 42 may be provided in the check-in terminal 21 of the check-in counter 1 or the late arrival detection device 6 instead of the tag management device 4.

  The RFID reader information / identification information receiving unit 43 receives identification information and RFID reader information transmitted from the RFID reader 3. The RFID reader information / identification information receiving unit 43 receives the RFID reader position information and the identification information acquisition time when the RFID reader 3 transmits the RFID reader position information and the identification information acquisition time.

  The RFID reader position information storage unit 44 stores RFID reader position information, which is information about the position where the RFID reader 3 is installed, in association with the RFID reader information for identifying the RFID reader 3 installed at various places. To do.

  The RFID tag position information acquisition unit 45 uses the RFID reader information received by the RFID reader information / identification information receiving unit 43 and the RFID reader position information stored in the RFID reader position information storage unit 44 to obtain identification information. The position where the acquired RFID reader 3 is installed is acquired. Here, as described above, the RFID reader 3 reads the identification information stored in the RFID tag 81 (boarding pass 8) that has passed in the vicinity, and transmits the identification information. Therefore, the RFID tag position information acquisition unit 45 acquires the rough location of the passenger holding the RFID tag 81 (boarding pass 8) (of the wireless IC tag) by acquiring the installation position of the RFID reader 3 that acquired the identification information. One of the location information). That is, the RFID tag position information acquisition unit 45 sets the rough current location of the RFID tag 81 (boarding pass 8, passenger) that stores the identification information acquired by the RFID reader 3, and installs the RFID reader 3 that acquired the identification information. It can be acquired as a position.

  For each piece of identification information, the RFID tag position information acquisition unit 45 stores the RFID reader information (RFID reader position information) from which the identification information has been acquired in the point passage information storage unit 46. Thereby, the point passage information storage unit 46 uses the tag passage information (position information history) for the identification information (the boarding pass 8) and the history (tag passage order, position information) of the RFID reader 3 through which the identification information has passed. Information). When the RFID reader information / identification information receiving unit 43 receives the identification information acquisition time, the RFID tag position information acquisition unit 45 associates the identification information acquisition time with the RFID reader information and stores the point passage information storage unit. 46 can be stored.

  As described above, the point passage information storage unit 46 stores, for each piece of identification information, the history (tag passage order) of the RFID reader 3 in which the identification information (boarding pass 8) has passed in the vicinity as tag passage information. As will be described later, the tag passage information is transmitted to the late arrival detection device 6 and used when estimating the estimated current location or specifying a specific action pattern. The point passage information storage unit 46 may be configured to be included in the late arrival detection device 6.

  The queue monitoring camera 5 includes a camera unit 51 and an image processing unit 52. As described above, the queue monitoring camera 5 is installed in a place where a queue is considered to occur. Specifically, for example, the queue monitoring camera 5 is installed in a baggage check counter, a security checkpoint, an immigration checkpoint, or the like. Note that the boarding guidance system 1 does not necessarily have to include a plurality of queue monitoring cameras 5 depending on the size of the airport, the expected occurrence of queues, and the like.

  The camera unit 51 photographs a queue generated at a security checkpoint where the queue monitoring camera 5 is installed or an immigration checkpoint. Then, the camera unit 51 transmits the video captured by the camera unit 51 to the image processing unit 52. Thereafter, the image processing unit 52 calculates the expected waiting time of the matrix using the video taken by the camera unit 51. As the camera unit 51, for example, a general surveillance camera can be used. Therefore, the detailed configuration of the camera unit 51 is omitted.

  The image processing unit 52 detects and tracks a person (passenger) based on the video captured by the camera unit 51, and calculates the waiting time of the matrix based on the behavior of the person. The image processing unit 52, for example, tracks any one passenger and calculates the expected waiting time of the matrix by measuring the time from lining up in a row until reaching the top of the row. In addition, the image processing unit 52 measures, for example, the total number of people lined up in the queue, the number of people who join the queue, and the number of people who leave the queue per hour, Calculate the expected waiting time of the matrix using a mathematical model. In this way, the image processing unit 52 can calculate the expected waiting time of the matrix by various methods. Therefore, the matrix waiting time calculation by the image processing unit 52 is not limited to the above case, and various methods capable of calculating the matrix waiting time can be employed. When calculating the expected waiting time of the matrix, the image processing unit 52 transmits the calculated expected waiting time of the matrix to the late arrival detection device 6.

  Note that the queue monitoring camera 5 may be configured only by the camera unit 51. In that case, for example, the boarding guidance system 1 includes an image processing device in addition to the queue monitoring camera 5, and the boarding guidance system 1 is configured so that the expected waiting time of the queue is calculated by the image processing device. It is possible. Further, for example, the delay detection device 6 may be configured to have a function as the image processing unit 52.

  The boarding delay detection device 6 is an information processing device including an arithmetic device and a storage device. The boarding delay detection device 6 implements each function described later by the arithmetic device executing a program stored in the storage device.

  As shown in FIG. 7, the late arrival detection device 6 executes a program stored in the storage device, whereby an operation information storage unit 61, a specific behavior pattern storage unit 62, a matrix expected waiting time storage unit 63, and an RFID tag A current location estimating unit 64, a required time calculating unit 65, a required time warning time comparing unit 66, a history action pattern specifying unit 67 (position history action pattern specifying means), and a warning information notifying unit 68 are realized.

  The operation information storage unit 61 stores operation information such as a boarding time of an airplane that leaves and arrives at an airport provided with the boarding guidance system 1. As will be described later, the late arrival detection device 6 compares the operation information (boarding time, warning time) stored in the operation information storage unit 61 with the required time calculated by the required time calculation unit 65, for example, thereby warning. The time for performing is calculated. Note that if the delay detection device 6 is configured such that the warning time such as the boarding time can be acquired by a method such as using the warning time stored in the RFID tag 81, the delay detection device 6 is not necessarily provided with the operation information storage unit. 61 may not be provided.

  The specific action pattern storage unit 62 stores a specific action pattern (predetermined action pattern) to be specified by a history action pattern specifying unit 67 described later. As will be described later, the history behavior pattern specifying unit 67 includes the specific behavior pattern stored in the specific behavior pattern storage unit 62 and the tag passage information (position) stored in the point passage information storage unit 46 of the tag management device 4. Information history information), it is determined whether or not the tag passage order indicated by the tag passage information matches the specific action pattern.

  Here, the specific action pattern refers to an action that is expected to take time among actions that can be taken until the passenger arrives at the boarding gate. Specifically, for example, a passenger moving around an area where restaurants are gathered is expected to take time to eat after searching for a store. In addition, for example, a passenger who makes a round trip to and from a duty-free shop may be distracted by shopping and forget the boarding time. Therefore, a specific action pattern is an action that specifies in advance an action that may take a long time to reach such a boarding gate.

  In general, it is impossible to spread the RFID reader 3 seamlessly. Therefore, the result of the passenger's action is stored as a discrete value for each point (RFID reader 3) called tag passage information. Therefore, the specific action pattern is also defined by the passing order of the RFID tags 81 (the history of the RFID reader 3 that the RFID tag 81 has passed in the vicinity).

For example, when installed in a position that is associated with the RFID reader 3 and store or area, and the installation position of the RFID reader 3 in the vicinity of the store X and the P _x. At this time, if the passenger moves as “Store A → Gate B → Store C → Store D → Store E”, the tag passing order S indicating the order of the RFID reader 3 through which the RFID tag (boarding pass 8) has passed is S = {P _A , P _B , P _C , P _D , P _E }.

As a method for creating a specific action pattern, for example, it is conceivable that an action scenario in the case of lagging in advance as described above is created in advance, and the tag passage order in the case of following the scenario is set as the specific action pattern. In other words, if there is a scenario where the passenger is likely to be late if he / she moves from “Store A → Gate B → Store C → Store D → Store E”, the tag passage order S = {P _A , P _B , P _C , P _D , P _E } are stored in the specific action pattern storage unit 62 as specific action patterns. In addition, as another method for creating a specific action pattern, for example, tag passage information of passengers who have missed in the past or passengers who are likely to be late is used as statistical information, and the order of highly relevant tag passage is determined as the specific action pattern. And so on. As will be described later, the specific action pattern can be obtained by taking into account the passage time between the RFID readers 3 indicated by the tag passage order and various statuses of the passengers.

The specific action pattern storage unit 62 sets a plurality of tag passing orders (specific action patterns) created in this way as a specific action pattern table T = {S ₁ , S ₂ , S ₃ , S ₄ , S ₅ }. The specific action pattern storage unit 62 stores this. That is, the specific behavior pattern storage unit 62 stores a plurality of tag passage orders (which may take passage time or the like) indicating the specific behavior pattern.

  The queue waiting time storage unit 63 stores the queue waiting time calculated by the image processing unit 52 of the queue monitoring camera 5. As described above, the image processing unit 52 of the queue monitoring camera 5 transmits the calculated expected waiting time of the queue to the late arrival detection device 6. Therefore, the delay detection device 6 that has received the expected waiting time of the matrix stores the expected waiting time of the received matrix in the expected matrix waiting time storage unit 63.

  The RFID tag current location estimating unit 64 acquires tag passing information from the point passing information storage unit 46, thereby estimating where the passenger carrying the RFID tag (boarding pass 8) is currently. Further, the RFID tag current location estimating unit 64 is configured to be able to confirm the time by confirming, for example, a clock incorporated in the delay detection device 6.

  The RFID tag current location estimating unit 64, for example, boarding the rough current location of the RFID tag (boarding pass 8) acquired by the RFID tag location information acquiring unit 45, that is, the arrangement position of the RFID reader 3 that finally acquired the identification information. It can be configured to estimate that the customer is the current location (position information of the wireless IC tag).

  Further, the RFID tag current location estimating unit 64 can infer the direction in which the passenger is traveling by using the tag passage information. Therefore, the RFID tag current location estimating unit 64 may be configured to estimate the location where the passenger is currently present (position information of the wireless IC tag) after analogizing the traveling direction of the passenger from the tag passage information, for example. I can do it. Hereinafter, an example of a method for estimating the place where the passenger is present after the RFID tag current location estimating unit 64 analogizes the traveling direction of the passenger from the tag passage information will be described.

First, it is assumed that the installation position of the RFID reader 3 that has passed last is P _n, and the installation position of the RFID reader 3 that has passed the last time is P _n−1 . Further, it is assumed that the distance from the installation position P _n of the RFID reader 3 to the boarding gate is represented as D (P _n ).

In such a case, when D (P _n )> D (P _n−1 ), that is, the RFID that has passed last more than the distance from the installation position of the RFID reader 3 that has passed immediately before to the boarding gate. When the distance from the installation position of the reader 3 to the boarding gate is longer, it can be seen that the passenger is moving away from the boarding gate.

Thus, when the passenger is moving away from the boarding gate, the RFID tag current location estimating unit 64 cannot determine when the passenger goes to the boarding gate. Therefore, as shown in FIG. 8, for example, the RFID tag current location estimating unit 64 estimates the position P _max (P _n ) that is not within the search range of other RFID readers and is farthest from the boarding gate. Estimated as the current position. Alternatively, the RFID tag current location estimating unit 64 estimates, for example, a position P _m (P _n ) away from the boarding gate by a predetermined distance as an estimated current location of the passenger. As described above, the RFID tag current location estimating unit 64 can be configured to move the estimated current location away from the boarding gate when it is impossible to determine when the passenger is going to the boarding gate. In this way, when it is not possible to determine when the passenger is going to the boarding gate, the estimated current location is estimated to be away from the boarding gate, thereby preventing the situation from occurring in time for the boarding time. Become.

On the other hand, when D (P _n ) <D (P _n−1 ), that is, the installation of the RFID reader 3 that has passed last than the distance from the installation position of the RFID reader 3 that has passed one pass before to the boarding gate. When the distance from the position to the boarding gate is shorter, it can be seen that the passenger is approaching the boarding gate.

  Here, even if it is determined that the passenger is approaching the boarding gate, the estimation error may increase if a long time has elapsed since the RFID tag 81 was last detected. In such a case, there is a possibility that the passenger is staying in a nearby area. Therefore, even if it is determined that the passenger is approaching the boarding gate, if a large amount of time has elapsed since the last detection of the RFID tag 81, the RFID tag current location estimating unit 64 Can be configured to determine that it is not heading to the boarding gate.

Specifically, the RFID tag current location estimating unit 64 acquires the identification information acquisition time of the RFID reader 3 that has passed last, which is stored in the tag passage information. Further, the RFID tag current location estimating unit 64 acquires time (current time) when estimating the current location. Then, the RFID tag current location estimating unit 64 compares the time T _last that has passed through the RFID reader 3 last time, the current time T _now, and the current location estimation threshold value T _n . When T _last −T _now > T _n , that is, when the elapsed time from the time when the RFID reader 3 was last passed to the current time exceeds the current position estimation threshold, the RFID tag current position estimation unit 64 It is determined that the passenger is not heading to the boarding gate. That is, in such a case, the RFID tag current location estimating unit 64 cannot determine when the passenger goes to the boarding gate. Therefore, the RFID tag current location estimating unit 64 estimates P _max (P _n ) or P _m (P _n ) as the estimated current position of the passenger.

It should be noted that when a large amount of time has elapsed since the last detection of the RFID tag 81, a sufficient number of RFID readers 3 cannot be installed in addition to the case where the passenger is staying in a nearby area. It may be considered that it takes time to move the reader 3 to the reading range. In other words, even if a long time has elapsed since the last detection of the RFID tag 81, it may simply be moving. Therefore, in order to cope with such a case, the current position estimation threshold value T _n may be configured to be able to be changed according to the installation position P _n of the RFID reader 3. That is, the RFID tag current location estimation unit 64 may be configured to set the current location estimation threshold value T _n according to the distance from the installation location P _n of the RFID reader 3 to the installation location of the adjacent RFID reader 3.

Finally, if D (P _n ) <D (P _n−1 ) and T _last −T _now <T _n , that is, it is determined that the passenger is heading to the boarding gate, and the RFID reader If 3 from passing through the end has not passed the threshold T _n worth of time, RFID tag current position estimating unit 64 estimates the estimated current position as headed directly boarding gate. In this case, the RFID tag current location estimating unit 64 lasts the elapsed time T _last − at the normal walking speed among the roads when the RFID reader 3 finally goes directly from the position _Pn where the RFID tag 3 detected the RFID tag 81 to the boarding gate. T _now min proceeds position _{P (P n, T last -T} now) it is assumed that it is estimated as the estimated current position (see FIG. 8). In addition, you may change the normal walking speed used for calculation, for example with statuses, such as a passenger's age.

  The above is an example of a method for estimating the place where the passenger is present after analogizing the traveling direction of the passenger from the tag passage information by the RFID tag current position estimating unit 64.

  The required time calculation unit 65 uses the estimated current location estimated by the RFID tag current location estimation unit 64 and the expected waiting time of the matrix stored in the matrix expected waiting time storage unit 63 to move from the estimated current location to the boarding gate. Calculate the required time. Specifically, the required time calculation unit 65 obtains the distance from the estimated current location to the boarding gate, and then multiplies the distance from the estimated current location to the boarding gate by the normal walking speed, from the estimated current location to the boarding gate. Calculate the time it takes to move. Then, the required time calculation unit 65 calculates the required time to the boarding gate by adding the expected waiting time of the matrix to the time required to move from the estimated current location to the boarding gate.

  The required time warning time comparing unit 66 and the required time calculated by the required time calculating unit 65 and a predetermined warning time (for example, the boarding time stored in the operation information storage unit 61 and the warning time transmitted by the RFID reader 3). And compare. If the required time warning time comparison unit 66 determines that the required time is not in time for the warning time, the warning time notification unit 68 instructs the warning notification unit 7 to issue a warning through a warning information notification unit 68 described later.

  On the other hand, if the required time warning time comparing unit 66 determines that the required time is in time for the warning time, the history action pattern specifying unit 67 described later determines whether the passenger's tag passing order matches the specific action pattern. Send an instruction to make a decision. And when the history action pattern specific | specification part 67 judges that a passenger's tag passage order corresponds to a specific action pattern, the required time warning time comparison part 66 sets time predetermined for every specific action pattern as required time. In addition, it is determined whether or not it is in time for the boarding time. Further, when it is determined that the added required time is not in time for the boarding time, an instruction is given to the warning notification unit 7 through the warning information notification unit 68.

  The required time warning time comparison unit 66 takes into account the specific action pattern specified by the historical action pattern specifying unit 67 from the beginning, and the boarding time stored in the flight information storage unit 61 taking into account the specific action pattern. You may comprise so that time may be compared.

  The required time warning time comparing unit 66 compares the required time calculated by the required time calculating unit 65 with, for example, a time (warning time) 10 minutes before the boarding time stored in the operation information storage unit 61. You may comprise. That is, the predetermined warning time is not limited to the boarding time, but may be earlier than the boarding time, such as 10 minutes before the boarding time.

  The history action pattern specifying unit 67 compares the tag passing order indicated by the tag passing information stored in the point passing information storage unit 46 of the tag management device 4 with each specific action pattern stored in the specific action pattern storage unit 62. . Then, the history action pattern specifying unit 67 specifies whether or not the tag passing order indicated by the tag passing information corresponds to the specific action pattern based on the comparison result between the tag passing order and the specific action pattern.

  As a specific action pattern specifying method by the history action pattern specifying unit 67, for example, a method in which the specific action pattern is specified by the tag passing order completely matching the specific action pattern can be considered. However, the detection of the RFID tag 81 cannot always be detected stably depending on the distance from the RFID reader 3 and the shielding object. In addition, it is easy to track the behavior of passengers by installing a large number of RFID readers 3, but in this case, even a similar behavior may not be detected as a specific behavior pattern with a slight difference. Therefore, even if the specific action patterns do not match in the tag passing order, the similarity between the tag passing order and the specific action pattern is obtained. If the similarity exceeds a certain degree of similarity, the tag passing order corresponds to the specific action pattern. It can be considered that the history behavior pattern specifying unit 67 is configured so as to be determined.

As a method for measuring the similarity, for example, the calculation of the Levenshtein distance (editing distance) may be applied to measure the similarity between the tag passage order and the specific action pattern. Here, the Levenshtein distance refers to the minimum number of steps required to transform one character string into another character string by inserting, deleting, or replacing characters. That is, the history behavior pattern specifying unit 67, the separated state of the tag passing order and the specific behavior pattern is measured, when separated state of the tag passing order and the specific behavior pattern is less than the edit distance threshold T _x a predetermined The tag passing order can be determined to correspond to a specific action pattern.

For example, the tag passage order indicated by the tag passage information is “Store A → Gate B → Store C → Store E”, that is, the passenger is in the tag passage order S _n = {P _A , P _B , P _C , P _E }. Further, it is assumed that the specific action pattern storage unit 62 stores a specific action pattern S ₁ = {P _A , P _B , P _C , P _D , P _E }. Furthermore, it is assumed that the edit distance threshold T _x = 2 is set in advance. In such a case, the tag passing order _{S n = {P A, P} B, P C, P E} identify behavioral patterns _{S 1 = {P A, P} B, P C, P D, P E} deformed to, it is necessary to insert a _{P D} to _{S n.} That is, to deform from S _n to S _1, it is seen that it is necessary to perform one operation of inserting the character. Therefore, it can be seen that the Levenshtein distance d (S _n , S ₁ ) = 1 between the tag passage order and the specific action pattern. On the other hand, the edit distance threshold T _x = 2. Therefore, when comparing the Levenshtein distance d (S _n , S ₁ ) = 1 and the edit distance threshold T _x = 2, the Levenshtein distance d (S _n , S ₁ ) is smaller than the edit distance threshold T _x. I understand that Thus, the history behavior pattern specifying unit 67 will be determined to be similar to the tag passing order S _n and a specific behavior pattern S _1.

  In addition, as a specific action pattern specifying method by the history action pattern specifying unit 67, in addition to the case where only the tag passing order is used as described above, for example, it is conceivable to consider the passing time. For example, when the RFID reader 3 installed in a restaurant reads the RFID tag 81 and the tag passage information is not updated, the passenger may be eating at the store. Therefore, when the RFID reader 3 installed in the restaurant reads the RFID tag 81 and the RFID tag 81 is not read by the RFID reader 3 for a predetermined period of time, a specific action pattern is set. You will be able to add time that you think will be needed by the meal. In this case, for example, it is conceivable to add an average stay time that differs depending on the store to the required time to reach the boarding gate. For example, it is assumed that the passenger is heading straight toward the boarding gate at a faster pace than usual. In this case, it is considered that the passenger is rushing to the boarding gate. Therefore, it is possible to suppress the warning by discounting the required time by using a specific action pattern when the tag passing order is straight toward the boarding gate and each passing time is not more than a predetermined threshold. Become.

  Further, the specific action pattern specifying method by the history action pattern specifying unit 67 may be configured to take into account the status, date and time of the passenger, season, etc. in addition to the tag passing order and the passing time. For example, it is conceivable to divide specific action patterns that may be applicable depending on the age and gender of the passenger. For example, the store may be closed depending on the time. Therefore, in such a case, it is conceivable to configure the history behavior pattern specifying unit 67 so as to exclude a scenario of staying in the closed store (a specific behavior pattern that is considered to stay). In this way, by taking into account external factors that affect the behavior of passengers, the accuracy of behavior pattern estimation can be increased.

  When the history action pattern specifying unit 67 determines that the tag passing order corresponds to the specific action pattern, the history action pattern specifying unit 67 notifies the required time warning time comparing unit 66 to that effect and adds a predetermined time to the required time, and then again. You will be instructed to make a comparison. In addition, the predetermined time added by the required time warning time comparison part 66 can be changed for every specific action pattern.

  The warning information notifying unit 68 determines that the passenger is not in time for the boarding time as a result of the comparison between the required time by the required time warning time comparing unit 66 and the warning time such as the boarding time (required from the current time). If the warning time is exceeded when time elapses), the warning notification unit 7 is notified to issue a warning.

  The warning notification unit 7 receives a notification from the warning information notification unit 68 and issues a warning to passengers who are likely to be late for the boarding time. For example, the warning by the warning notification unit 7 sends an instruction to the warning display unit 71 in the vicinity of the estimated current position of the passenger (RFID 81) that is a warning target to display that there is a risk that the passenger will be late. Is done. Here, the warning display unit 71 is a display or the like installed at various locations in the airport including the boarding guidance system 1. Therefore, the warning by the warning notification unit 7 is performed, for example, by displaying on the displays installed at various locations in the airport that there is a risk that the passenger will be late. In this way, the warning notification unit 7 can give a warning using existing facilities at the airport. Further, the warning notification unit 7 issues a warning via the network 72 by, for example, sending an e-mail indicating that there is a risk of being late to the passenger's portable terminal 73 who is the owner of the RFID tag 81 to be warned. I can do it. The warning notification unit 7 can perform the above warning by using information stored in the identification information / passenger information storage unit 42.

  In the present embodiment, the tag management device 4 and the delay detection device 6 are different information processing devices. However, the tag management device 4 and the late arrival detection device 6 may be configured as one information processing device.

  The calculation of the required time by the required time calculation unit 65 and the comparison by the required time warning time comparison unit 66 are configured to be performed each time the RFID reader 3 reads the RFID tag 81, for example, or at predetermined time intervals. It can be configured to be performed regularly. In addition, for example, it is determined that there is a possibility that the passenger will be late if the predetermined time before the boarding time, and the required time calculation unit 65 calculates the required time by the predetermined time before the boarding time. It may be configured to start. In the present invention, the timing for calculating the required time by the required time calculating unit 65 and the comparison by the required time warning time comparing unit 66 are not particularly limited.

  Further, the warning by the warning notification unit 7 may include various general methods such as making an announcement in the hall and notifying airport staff, in addition to the case exemplified above.

  The above is the configuration of the boarding guidance system 1 in the present embodiment. Next, the operation of the boarding guidance system 1 in this embodiment will be described with reference to FIGS. 9 to 11. First, the overall flow of the boarding guidance system 1 will be described with reference to FIG.

(Operation)
First, the passenger checks in. As a result, the boarding pass 8 with the RFID tag is delivered to the passenger (S001). The RFID tag 81 given to the boarding pass 8 stores identification information.

  Subsequently, the passenger who has received the boarding pass 8 as described above goes to the boarding gate through a security check and the like while approaching the store or the like while holding the boarding pass 8. Here, a plurality of RFID readers 3 are installed in advance at various locations in the airport. Therefore, when the passenger passes near the RFID reader 3 installed in advance, the RFID reader 3 reads the RFID tag 81 (identification information stored in) of the passenger passing the vicinity.

  The RFID reader 3 that has read the identification information sends the read identification information and RFID reader information to the tag management device 4. Then, the RFID tag position information obtained by reading the identification information is acquired by the tag management device 4 that has received the identification information and the RFID reader information (S002).

  Further, the tag management device 4 stores RFID reader information indicating the RFID reader 3 that has read the identification information for each identification information in the point passage information storage unit 46. As a result, the tag passage information indicating the tag passage order of each RFID tag 81 is stored in the point passage information storage unit 46 (S003).

  The camera unit 51 of the queue monitoring camera 5 takes a picture of the queue generated at the installed position. Then, the image processing unit 52 analyzes the image of the queue. By analyzing the images in the queue in this way, the queue monitoring camera 5 calculates the expected waiting time of the queue (S004). Subsequently, the queue monitoring camera 5 transmits the estimated waiting time of the calculated queue to the late arrival detection device 6. Thereafter, the delay detection device 6 that has received the expected waiting time of the matrix stores the expected waiting time of the matrix in the expected matrix waiting time storage unit 63 (S005).

  Subsequently, for example, when it is time when there is a possibility that a passenger who is not in time for the boarding time may occur, it is periodically determined whether or not the passenger is in time for the boarding time. First, the RFID tag current location estimating unit 64 of the late arrival detection device 6 acquires tag passing information from the point passing information storage unit 46. Then, the RFID tag current location estimating unit 64 estimates the estimated current location of the passenger (S006). Subsequently, the required time calculation unit 65 of the late arrival detection device 6 adds the expected waiting time of the matrix to the travel time obtained from the distance between the estimated current location and the boarding gate, thereby moving the estimated current location to the boarding gate. The required time is calculated (S007). After that, the required time warning time comparison unit 66 compares whether the passenger is in time for the boarding time from the required time and the warning time (S008, S009).

  Here, when the required time warning time comparison unit 66 determines that the passenger is not in time for the boarding time, the information of the passenger is transmitted to the warning notification unit 7 (S012), and a warning is given ( S013).

  On the other hand, when the required time warning time comparing unit 66 determines that the passenger is in time for the boarding time, the history behavior pattern specifying unit 67 determines whether the tag passage order matches the specific action pattern. Is called. When the history action pattern specifying unit 67 determines that the tag passing order matches the specific action pattern, the boarding time is again calculated by the required time warning time comparing unit 66 after a predetermined time is taken into account. A comparison is made as to whether or not the passengers are in time (S010, S011).

  After that, when the required time warning time comparison unit 66 determines that the passenger is not in time for the boarding time as a result of the comparison again (S011), the passenger information is transmitted to the warning notification unit 7 (S012). A warning is issued (S013).

  On the other hand, if it is determined by the comparison again that the boarding time is in time (S011), no warning is given to the passenger, and the current location is re-established, for example, after waiting for the RFID tag to be detected again or when a certain time has passed. From this estimation, it is determined whether or not it is in time for the boarding time.

  The above is the overall flow of the boarding guidance system 1. Next, the operation when the RFID tag current location estimating unit 64 estimates the estimated current location will be described with reference to FIG.

The RFID tag current location estimating unit 64 first determines whether or not the passenger is approaching the boarding gate with reference to the tag passing order indicated by the tag passing information (S021). When D (P _n ) <D (P _n−1 ) does not hold (S022), the estimated current position of the passenger is estimated as P _max (P _n ) (S023).

That is, when the distance from the installation position of the RFID reader 3 that has passed last to the boarding gate is longer than the distance from the installation position of the RFID reader 3 that has passed the previous one to the boarding gate, the current location of the RFID tag The estimation unit 64 determines that the passenger is moving away from the boarding gate. Therefore, the RFID tag current location estimating unit 64 cannot determine when the passenger goes to the boarding gate. Therefore, the RFID tag current location estimating unit 64 estimates the position P _max (P _n ) that is not within the search range of another RFID reader and is farthest from the boarding gate as the estimated current position of the passenger. In this way, when it is not possible to determine when the passenger is going to the boarding gate, the estimated current location is estimated to be away from the boarding gate, thereby preventing the situation from occurring in time for the boarding time. Become.

On the other hand, when D (P _n ) <D (P _n−1 ) is satisfied (S 022), the RFID tag current location estimation unit 64 has passed a long time since the last RFID reader 3 acquired the RFID tag 81. It is determined whether or not it is present (S024). When T _last −T _now > T _n (S025), that is, when the elapsed time from the last pass through the RFID reader 3 to the current time exceeds the current position estimation threshold, the RFID tag current position is estimated. The unit 64 determines that the passenger is not heading to the boarding gate. When the RFID tag current location estimating unit 64 determines in this way, the RFID tag current location estimating unit 64 estimates P _max (P _n ) as the estimated current position of the passenger (S023).

On the other hand, when the RFID tag current location estimating unit 64 determines that T _last −T _now > T _n is not satisfied (S025), the RFID tag current location estimating unit 64 determines that the passenger is directly heading to the boarding gate. Will be estimated. In this case, the RFID tag current location estimating unit 64 lasts the elapsed time T _last -T _now at the normal walking speed among the roads when the RFID reader 3 finally goes directly from the position P _n where the RFID tag 3 detected the RFID tag 81 to the boarding gate. The position P (P _n , T _last −T _now ) that is assumed to have been advanced is estimated as the estimated current location (S026). In addition, you may change the normal walking speed used for calculation, for example with statuses, such as a passenger's age.

  With the above operation, the RFID tag current location estimating unit 64 estimates the estimated current location. Next, the operation when the history action pattern specifying unit 67 specifies the specific action pattern from the tag passing order indicated by the tag passing information will be described with reference to FIG.

First, the history behavior pattern specifying unit 67 performs the determination of whether the tag passing order _{S n} is contained in a particular behavior pattern table T (S031, S032). Here, if the tag passing order S _n is determined to be contained in a particular behavior pattern table T (i.e., entirely consistent with certain behavior patterns tag passing order S _n is contained in a particular behavior pattern table T In this case, the history action pattern specifying unit 67 instructs the required time warning time comparing unit 66 to add a predetermined time for each specific action pattern to the required time (S033).

On the other hand, if (S032) the tag passing order S _n is determined not to be included in a particular behavior pattern table T, the history behavior pattern specifying unit 67, the tag passing order and the Levenshtein distance between the specific behavior pattern It calculates | requires for every specific action pattern (S034). Then, so that it is determined whether or not the Levenshtein distance obtained is equal to or less than the edit distance threshold T _x (S035).

Here, in the case Levenshtein distance tag passing order and the specific behavior pattern is less than the edit distance threshold T _x (S036), the history behavior pattern specifying unit 67, the tag passing order is consistent with the specific behavior pattern to decide. Then, the history action pattern specifying unit 67 instructs the required time warning time comparing unit 66 to add a predetermined time for each specific action pattern to the required time (S033).

On the other hand, when Levenshtein distance tag passing order and the specific behavior pattern is edit distance threshold T _x above (S036), the history behavior pattern specifying unit 67, is not performed time additional instructions for the required time become. That is, the history behavior pattern specifying unit 67 instructs the required time warning time comparing unit 66 not to add time to the required time.

  The above is the operation when the history behavior pattern identification unit 67 identifies the specific behavior pattern from the tag passage order indicated by the tag passage information.

  As described above, the boarding guidance system 1 according to this embodiment includes the RFID reader 3, the tag management device 4, and the boarding delay detection device 6. With this configuration, the boarding guidance system 1 can read the RFID tags 81 held by the passengers by the RFID readers 3 installed at various locations in the airport. Therefore, the boarding guidance system 1 can grasp the general location of the passenger. The late arrival detection device 6 can calculate the required time from the passenger's whereabouts to the boarding gate. As a result, it becomes possible to compare the required time with the boarding time, and by using the result of the comparison, it becomes possible to search for a non-passenger and warn at an appropriate time.

  The boarding guidance system 1 according to the present embodiment includes a queue monitoring camera 5. With such a configuration, the boarding guidance system 1 can monitor a queue generated before heading to the boarding gate and calculate an expected waiting time of the queue. As a result, it becomes possible to compare the required time with the expected waiting time of the queue and the boarding time, and by using the result of the comparison, search and warning of non-passengers at a more appropriate time Can be done.

  The boarding guidance system 1 according to the present embodiment includes a point passage information storage unit 46 and an RFID tag current location estimation unit 62. With such a configuration, the boarding guidance system 1 can grasp the passenger's location more accurately by using the tag passage information stored in the point passage information storage unit 46. As a result, it becomes possible to calculate a more appropriate time, and to search for and warn a non-passenger at a more appropriate time.

  The boarding guidance system 1 according to this embodiment includes a point passage information storage unit 46, a specific behavior pattern storage unit 62, and a history behavior pattern specification unit 67. With this configuration, the boarding guidance system 1 can identify actions that are likely to take time among the actions of passengers. As a result, when the passenger is performing an action that seems to take time, the time according to the action can be added to the required time, and the search for a non-passenger at a more appropriate time, A warning can be made.

  In the present embodiment, the boarding gate is used as a predetermined specific place for calculating the distance from the estimated current location of the passenger. However, the boarding guidance system 1 calculates the distance between a specific checkpoint (for example, a baggage check counter, immigration) and the estimated current location of the passenger, and determines whether or not the specific checkpoint can be reached by a predetermined time. Such a determination may be made. That is, the boarding guidance system 1 may be configured to include a plurality of checkpoints and perform multistage determination.

<Embodiment 2>
Next, a second embodiment of the present invention will be described.

(Constitution)
The boarding guidance system 8 in the present embodiment has a configuration substantially similar to that in the first embodiment. Therefore, only the characteristic part in the present embodiment will be described below.

  The boarding guidance system 8 in the present embodiment is greatly different from the first embodiment in that it does not include the queue monitoring camera 5. The boarding guidance system 8 in the present embodiment includes a sensor that can determine the required time of the queue instead of the queue monitoring camera 5.

  Specifically, for example, the boarding guidance system 8 is provided with light blocking sensors for detecting the passage of people at the entrances and exits of places (such as immigration and security checkpoints) where a procession is considered to occur. By installing the light blocking sensor in this way, it is possible to count the number of people in the queue and the number of inflows and outflows per hour. Therefore, the expected waiting time of the queue can be determined using a mathematical model of the queue.

  That is, even if a light blocking sensor is provided instead of the queue monitoring camera 5, the expected waiting time of the queue can be calculated, so that the object of the present invention can be achieved.

  In addition, the boarding guidance system 8 includes, for example, an RFID reader 3 that reads the RFID tag 81 at the entrance of the queue instead of the queue monitoring camera 5 and the light blocking sensor. By providing the RFID reader 3 in this way, for example, it is possible to obtain the average of the time required to pass through the matrix and to determine the expected waiting time of the matrix.

<Embodiment 3>
Next, a third embodiment of the present invention will be described with reference to FIG. FIG. 12 is a block diagram showing an outline of the configuration of the information processing apparatus 9 in the present embodiment.

  As shown in FIG. 12, the information processing apparatus 9 in this embodiment includes a wireless IC tag position information acquisition unit 91, a required time calculation unit 92, and a warning unit 93.

  The wireless IC tag position information acquisition means 91 acquires identification information stored in advance in a wireless IC tag attached to an object held by a person with a plurality of wireless IC tag readers installed at predetermined locations, and stored in advance. The position information of the wireless IC tag is acquired based on the position information of the wireless IC tag reader and the identification information acquired by the wireless IC tag reader.

  That is, when the wireless IC tag reader acquires identification information, the wireless IC tag position information acquisition unit 91 acquires the identification information acquired by the wireless IC tag reader. Then, by using the position information of the wireless IC tag reader stored in advance and the acquired identification information, the position of the wireless IC tag reader from which the identification information has been acquired is acquired as the position information of the wireless IC tag.

  Thereafter, the wireless IC tag position information acquisition unit 91 transmits the acquired position information of the wireless IC tag to the required time calculation unit 92.

  The required time calculation unit 92 takes the time required to move from the location indicated by the location information to a predetermined specific location according to the location information of the wireless IC tag acquired by the wireless IC tag location information acquisition unit 91. Is calculated.

  That is, the required time calculation unit 92 first acquires the position information of the wireless IC tag transmitted by the wireless IC tag position information acquisition unit 91. Subsequently, the required time calculation unit 92 calculates the required time required to move from the location indicated by the acquired position information of the wireless IC tag to a predetermined specific location.

  Here, the calculation of the required time by the required time calculation means 92 is calculated according to the distance traveled from the location indicated by the acquired position information of the wireless IC tag to a predetermined specific location, for example. In addition, the required time calculation unit 92 includes a case where there is some extra time between the location indicated by the acquired location information of the wireless IC tag and a predetermined specific location. The required time may be calculated.

  Thereafter, the required time calculation unit 92 transmits the calculated required time to the warning unit 93.

  The warning means 93 gives a predetermined warning in advance according to the required time calculated by the required time calculation means 92 and a predetermined warning time.

  That is, the warning unit 93 first receives the required time transmitted by the required time calculation unit 92. Subsequently, the warning means 93 compares the received required time with a predetermined warning time. And the warning means 93 will perform the predetermined | prescribed predetermined warning according to the received required time and the predetermined warning time.

  Here, the predetermined warning by the warning means 93 can be performed using various general warning means. Therefore, here, the way of warning by the warning means 93 is not particularly limited.

  As described above, the information processing apparatus 9 according to the present embodiment includes the wireless IC tag position information acquisition unit 91, the required time calculation unit 92, and the warning unit 93. With such a configuration, the information processing apparatus 9 can acquire position information of a person (a wireless IC tag held by the person). Further, based on the acquired position information, it is possible to calculate the time required for moving from a place indicated by the position information to a predetermined specific place. As a result, a predetermined warning can be given in accordance with the calculated required time and a predetermined warning time. That is, the information processing device 9 can warn a non-passenger at an appropriate time according to the required time and the warning time.

  The information processing apparatus described above can be realized by incorporating a predetermined program into the information processing apparatus. Specifically, a program according to another embodiment of the present invention is stored in advance in a wireless IC tag attached to an object held by a person with a plurality of wireless IC tag readers installed at predetermined locations in the information processing apparatus. A wireless IC tag position information acquisition means for acquiring identification information and acquiring position information of the wireless IC tag based on the position information of the wireless IC tag reader stored in advance and the identification information acquired by the wireless IC tag reader; and a wireless IC tag A required time calculating means for calculating a required time for moving from a place indicated by the position information to a predetermined specific location according to the position information of the wireless IC tag acquired by the position information acquiring means; A program for realizing warning means for performing a predetermined warning in accordance with a required time calculated by the calculation means and a predetermined warning time.
