(First embodiment of the present invention)
A safety maintaining system according to the present embodiment will be described with reference to FIGS.
(1. Configuration)
FIG. 1 is a system outline diagram of a safety maintenance system according to the present embodiment. The safety maintenance system 100 includes a management server 110 that manages the entire system, a ticket issuing device 120 that issues a ticket 101, and a movement detection device 130 that detects the movement of the ticket 101.

  A user of the system purchases or receives the ticket 101 with the ticket issuing device 120 and moves within a predetermined area while holding the acquired ticket 101. Within the predetermined area is, for example, the area of entertainment facilities such as amusement parks, parks, movie theaters, concert venues, and facilities such as department stores and large shopping malls. In the present embodiment, the description will be given assuming that the predetermined area is the amusement park.

The ticket 101 has a function of communicating identification information (for example, a non-contact type IC card). When the user passes near the movement detection device 130 while holding the ticket 101, the movement detection device A reader 130 reads the identification information of the ticket 101. The movement detection device 130 is installed at an arbitrary plurality of locations (for example, an entrance gate for an attraction, a restaurant table, etc.) within a predetermined area. Information read by the movement detection device 130 is transmitted to the management server 110 and managed in the management server 110.
The management server 110 performs grouping by estimating the accompanying relationship between users based on the information received from the movement detection device 130.

  FIG. 2 is a diagram schematically showing an outline of the safety maintenance system according to the present embodiment. At the time of entering the amusement park, the user A purchases the ticket No. 1 and the user B purchases the ticket No. 2 at the same time, and enters the park together. At this time, tickets No. 1 and No. 2 are purchased at the same time and are associated with each other by a related number. That is, as shown in FIG. 1, the related number of the No1 ticket is No2, and the related number of the No2 ticket is No1.

  Also, the user C enters the ticket after purchasing a No. 3 ticket with a delay. If the users A, B, and C are related companions, there is no related number only for the ticket of the user C even though they are related companions. In the present embodiment, the user C performs the same action and movement as the user A and the user B in the park, thereby calculating the relevance of each ticket 101.

  In FIG. 2, after user A and B enter, user C joins and user A takes another action (assuming that he has come home first), and then user B and C act together. And The user C acts together with the user B, so that No3 is added to the related number in the ticket 101 of the user B. In addition, No2 is added to the related number in the ticket 101 of the user C.

  When exiting from the park, it is possible to exit without any problem if the users holding the tickets 101 registered in the related numbers exit together. That is, if user B is together with user A or user C, he can leave without problem. If user C is with user B, he can leave without problems. When leaving alone, such as user A, or when leaving with a user whose related number is not registered, he / she can leave if there is no problem after checking the staff.

  FIG. 3 is a hardware configuration diagram of the management server in the safety maintenance system according to the present embodiment. The management server 110 includes a CPU 310, a RAM 320, a ROM 330, a hard disk (HD) 340, a communication I / F 350, and an input / output I / F 360. The ROM 330 and the HD 340 store an operating system (referred to as an OS), various programs, and the like. The ROM 330 and the HD 340 are read into the RAM 320 as necessary, and are executed by the CPU 310. The communication I / F 350 is an interface for communicating with other devices (here, the ticket issuing device 120 and the movement detection device 130). The input / output I / F 360 is an interface for receiving input from a keyboard, a mouse, or the like, or outputting data to a printer, a display, or the like. As this input / output I / F 360, USB, RS232C, or the like is used. Further, if necessary, a drive corresponding to a removable disk such as a magneto-optical disk, a floppy disk (registered trademark), a CD-R, or a DVD-R can be connected.

  FIG. 4 is a functional block diagram of the management server in the safety maintenance system according to the present embodiment. The management server 110 includes processing units such as a ticket issuing unit 410, a group management unit 420, an exit management unit 430, and an entrance management unit 440. Further, each information unit includes number management information 450, group management information 460, entrance / exit management information 470, exit person image information 480, and reference value management information 490.

  When the ticket issuing unit 410 receives a ticket issuing instruction for the ticket 101 from the ticket issuing device 120, the ticket issuing unit 410 refers to the number management information 450 and generates an issued information of the ticket 101 by assigning an identification number that can uniquely identify the ticket 101. And stored in the number management information 450. At this time, when a plurality of tickets 101 are issued together, since they are mutually related users, a related number is registered as related information, and number management is also performed as initial related information at the time of purchase. Stored in information 450. When the ticket issuing unit 410 issues the ticket 101, ticket information related to the issued ticket 101 is generated and stored in the group management information 460.

  When the group management unit 420 receives the information detecting the ticket 101 from the movement detection device 130, the group management unit 420 determines whether or not the plurality of tickets 101 are related based on the received information. Calculates relevance.

  Here, the configuration of the group management unit 420 will be described in detail. FIG. 5 is a functional block diagram of the group management unit of the management server in the safety maintenance system according to the present embodiment. The group management unit 420 includes processing units such as an association determination unit 421, an association degree calculation unit 422, and a weighting unit 423.

  The relevance determination unit 421 determines whether or not there is relevance between a plurality of ticket information transmitted from the movement detection device 130. The presence / absence of relevance is determined based on the identification number and time of the ticket 101 that has passed near the movement detection device 130. For example, it is determined that the tickets 101 that have passed within a predetermined time (for example, within 10 seconds) are related to each other, assuming that the users who are acting together hold the tickets 101.

The relevance calculation unit 422 calculates the relevance when the relevance determination unit 421 determines that there is relevance. Details of the calculation method of the relevance level will be described later. For example, the number of times it is determined that there is relevance, the installation location of the movement detection device 130, the reception order of the identification number of the ticket 101 transmitted from the movement detection device 130, It is calculated based on the presence or absence of another ticket 101 having
The weighting unit 423 weights each parameter when the relevance calculation unit 422 calculates the relevance.

  Related information such as the presence / absence of the relevance and the calculated relevance is stored in the group management information 460. Further, when the weighting unit 423 performs weighting, it is performed based on preset weighting information. The administrator may register the weighting information in advance in the reference value management information 490, for example.

  Returning to FIG. 4, when the admission management unit 440 detects the admission of the user holding the ticket 101 into the park, the admission management unit 440 adds the information of the ticket 101 to the admission / exit management information 470 and Flg indicating the admission / exit state. (Enter / exit Flg) is updated to “1: Entering”. Further, the related information of the ticket 101 that has entered together is recorded in the group management information 460.

  When the exit management unit 430 detects that the user holding the ticket 101 exits the park, the exit management unit 430 determines permission to exit based on the reference value of the reference value management information 490 preset by the administrator. If necessary, the user's face image is captured and stored in the exit person image information 480, and when the exit is permitted, the entrance / exit Flg of the entrance / exit management information 470 is updated to “0: exiting”. To do. When leaving is not permitted, a process for prompting the user to receive a check by a staff member is performed.

  Here, the data structure of each information unit will be described. FIG. 6 is a diagram illustrating an example of a data configuration in the safety maintenance system according to the present embodiment. FIG. 6A is a number management table showing the data structure of the number management information 450. The number management table is used when the ticket 101 is issued, and has items of ticket number, date, and initial related number. In the initial relation No., when a plurality of tickets 101 are purchased together at the time of purchase, a mutual relation number is registered as initial relation information. In FIG. 6A, the number 00001, the number 00002, and the number 00003 are purchased together and are associated with each other by the initial association number.

  FIG. 6B is an entrance / exit management table showing the data structure of the entrance / exit management information 470. The entrance / exit management table is used at the time of entrance or exit, and has items of ticket number, date, and entrance / exit Flg. When leaving the park, it is possible to leave without any problem only when the entry / exit Flg is “0: Exiting”.

  FIG. 6C is a group management table showing the data configuration of the group management information 460. The group management table is used when the movement detection device 130 detects the movement of the ticket 101, and includes items of ticket number, date, degree of association, and relation number. The related No. stores the number of the related ticket 101, and the related degree stores the related degree calculated by the related degree calculating unit 422.

  FIG. 6D is a reference value management table showing the data structure of the reference value management information 490. The reference value management table is used when determining the relevance of the ticket 101 at the time of leaving, and has an item of relevance setting value. If the relevance is equal to or higher than the set value set here, it is determined that there is relevance, and if the relevance is less than the set value, it is determined that there is no relevance. Moreover, you may make it store the weighting coefficient of the parameter used when calculating a relevance degree as needed.

FIG. 6E is a leaving image information table showing the data structure of the leaving person image information 480. The exit image information table is used when exiting and has items of ticket number, date, image data, and imaging time. What is recorded here is a face image of the person at the head of the group, and is used for confirmation when an incident such as take-away occurs.
Each data configuration is an example, and the administrator can arbitrarily design the data configuration.

(2. Operation)
FIG. 7 is a flowchart showing an operation at the time of ticket issuing processing in the security system according to the present embodiment. First, a ticket is issued based on a ticket issuing instruction from the ticket issuing device 120 (step S701). It is determined whether a plurality of issued tickets are issued together (step S702). When a plurality of sheets are issued together, the ticket number and the related number are registered in the number management information 450 and the group management information 460, respectively, and the relevance level is maximized (step S703). The reason why the degree of relevance is maximized is that the user who purchased the ticket 101 together is a companion who has certain relevance in the relationship of entering the park. If it is not the issue of a plurality of sheets, the ticket number is registered in the number management information 450 (step S704). The information of the ticket 101 issued to the entrance / exit management information 470 is registered with the entrance / exit Flg set to “0: exiting” (step S705), and the ticket issuing process is terminated.

  FIG. 8 is a flowchart showing the operation at the time of entry detection in the safety maintenance system according to the present embodiment. First, the movement detection device 130 reads the ticket No. of the ticket 101 and transmits it to the management server 110 (step S801). The entrance / exit Flg of the entrance / exit management information 470 is read from the transmitted ticket No (step S802). The entrance / exit Flg is updated to “1: entering” (step S803), and the entrance detection process is terminated.

  FIG. 9 is a flowchart showing an operation at the time of movement detection in the safety maintenance system according to the present embodiment. First, the movement detection device 130 reads the ticket No. of the ticket 101 and transmits it to the management server 110 (step S901). Based on the time when the ticket number is read, the ticket number of the ticket whose movement is detected within a predetermined time is acquired (step S902). It is determined whether or not the acquired ticket No. has already been registered as a related number (step S903). If it is not registered as a related number, the acquired ticket No. is newly registered in the related number (step S905). If it is already registered as a related number, it is determined whether or not the related degree is the maximum value (step S904). If the relevance is the maximum value, the movement detection process is terminated as it is. When a related number is newly registered or when the relevance level is not the maximum value, the relevance level is calculated (step S906).

  Here, the calculation of the degree of association will be described. As described above, the calculation of the relevance is performed based on the number of times determined to be relevant, the location where the movement is detected, the order in which the ticket numbers are received, and / or the presence / absence of other relevant ticket numbers. . FIG. 10 is a diagram illustrating an example of how a user moves in the safety maintenance system according to the present embodiment. Here, when three parents and children visit the amusement park, the first half illustrates the case where the mother and the child act together, and the second half illustrates the case where the father and the child act together. The entrance gate, exit gate, and each attraction and restaurant in the amusement park are equipped with a movement detection device 130. When the user passes the gate and eats at the same table, the movement detection device 130 displays the identification information of the ticket 101. Read and transmit to the management server 110.

  In FIG. 10, a mother and a child purchase a ticket together and pass through an entrance gate. At this time, the mother ticket and the child ticket are associated with each other, and the degree of association is the maximum value. Mother and child pass through Attraction A and Attraction B together. At this time, since the degree of association is already the maximum value, the group management information 460 is not updated. However, if there is another user who has passed through Attraction A and Attraction B together (a user who is not originally related), the ticket numbers of the other users are registered in the related numbers. After passing attraction B, he joined his father who entered separately, and after three people passed attraction C, they dine at the restaurant. At the time of passing through the attraction C, the mother and father and child and father tickets are associated with each other. Furthermore, relevance increases by eating at a restaurant.

  When calculating the degree of relevance based on the number of times determined to be relevant, the degree of relevance may be incremented each time it is determined to be relevant, or the number of additions increases. May be weighted by increasing. For example, when passing the attraction C, the relevance level between the father and the child is “1” (first relevance determination), and when eating at a restaurant, the second relevance determination is made. 2 may be added to the relevance level to obtain “3”. That is, n is added to the degree of relevance when determining the relevance for the nth time.

  Moreover, you may weight according to the location of the movement detection apparatus 130 when determination with a relevance degree is made. For example, when passing the attraction C, there is a high possibility of passing with other users, but the possibility of eating with other users at the same table in the restaurant is extremely low. Therefore, k × n (k: a weighting coefficient for each place, set to 1 for an attraction and set to 2 for a restaurant) is added to the degree of association.

  Furthermore, you may weight according to the order of passage which passed each attraction. FIG. 11 is a diagram illustrating an example of how a user is detected to move in the safety maintenance system according to the present embodiment. In FIG. 11, it is assumed that there is a matrix for entering the attraction, and the entrance is made in the order of a, b, father, child, mother, c, d, e, and f. At this time, if the child is used as a reference, the number of additions of relevance increases for the previous and subsequent users (father and mother), and weighting is performed so that the number of additions of relevance decreases as the order becomes farther from the child. I do. That is, the number of additions is increased as the ticket number is the closest in the order of receiving information from the movement detection device 130. Therefore, 1 / s × n (s: order from the reference ticket No.) is added to the relevance.

Returning to FIG. 10, the mother returns home after eating at the restaurant, and only the father and the child pass the attraction D. Here, when the attractions C are passed, the mother is acting together, but when the attractions D is passed, the mother is not acting together. Thus, in the behavior with the father in the state where there is a mother who has already been sufficiently associated with the child, there is a high possibility that the child and the father are related. In other words, the number of relevances is weighted according to the presence or absence of a companion with high relevance. Therefore, t × n (t: set to 1 when there is a highly related companion, set to 0.7 when there is no highly related companion) is added to the degree of relevance.
Note that a plurality of the above parameters may be used in combination depending on the situation. In addition, the numerical values in the description are merely examples and can be arbitrarily set by the administrator.

  When passing through the exit gate, if the degree of association between the father and the child exceeds the reference value set in the reference value management unit 490, the exit can be made without any problem. If it does not exceed, an instruction to check the staff will be output, and if there is no problem as a result of the check, you can leave. In addition, when leaving alone like a mother, an instruction to receive a check by a staff member is output, and if there is no problem as a result of the check, it is possible to leave.

  Returning to FIG. 9, when the degree of association is calculated, the degree of association of the group management information 460 is updated and the movement detection process is terminated.

  FIG. 12 is a flowchart showing an operation at the time of exit detection in the safety maintenance system according to the present embodiment. First, the movement detection device 130 reads the ticket No. of the ticket 101 and transmits it to the management server 110 (step S1201). It is determined whether or not the exit from the previous exit is within a predetermined time (step S1202). If it is not within a predetermined time since the previous exit, the process proceeds to step S1206. If it is within a predetermined time since the previous exit, the previous exit's ticket No is acquired (step S1203). The ticket number of the previous exit person is the ticket number of the ticket whose exit was detected immediately before. It is determined whether the ticket number of the previous exit is registered in the related number (step S1204). If it is not registered in the related number, the process proceeds to step S1206. If it is registered in the related number, it is determined whether or not the degree of relevance is greater than or equal to the reference value set in the reference value management information 490 (step S1205). If it is less than the reference value, the process proceeds to step S1206. If it is equal to or greater than the reference value, the entry / exit Flg is updated to “0: exiting” (step S1212).

  In step S1206, an alarm is generated and a photograph of the person leaving the face is taken. The image captured here is used for confirmation when an incident or the like occurs. It is determined whether there is a subsequent exit who leaves within a predetermined time (step S1207). If there is no subsequent exit who leaves within the predetermined time, the process proceeds to step S1211. If there is a subsequent exit who leaves within a predetermined time, the ticket number of the subsequent exit is acquired (step S1208). The ticket number of the subsequent exit person is the ticket number of the ticket whose exit was detected immediately after. It is determined whether or not the ticket number of the subsequent exit is registered in the related number (step S1209). If it is not registered in the related number, the process proceeds to step S1211. If it is registered in the related number, it is determined whether or not the degree of relevance is greater than or equal to the reference value set in the reference value management information 490 (step S1210). If it is less than the reference value, the process proceeds to step S1211. If it is equal to or greater than the reference value, the entry / exit Flg is updated to “0: exiting” (step S1212).

  In step S1211, it is checked whether there is an abnormality by the staff. If there is an abnormality, proceed to the next process without doing anything. If there is no abnormality, the entry / exit Flg is updated to “0: exiting” (step S1212). The entrance Flg is determined (step S1213). If “0: exiting”, exit is permitted, exits, and exit detection processing ends. If “1: Admission”, exit is not permitted, so exit cannot be performed and the exit detection process is terminated. If there is an abnormality in the check of the staff, there is a possibility that an incident such as removal has occurred, and deal with it promptly.

  If the ticket for adults can be differentiated from the ticket for children due to differences in fees, etc., when the ticket is issued, only the relevance and degree of association between the child ticket and the adult ticket are processed. May be. That is, in the case as shown in FIG. 10, processing is not performed for the relationship between the father and the mother and the degree of relationship, but only for the relationship between the child and the mother and the relationship between the child and the father. Even at the time of leaving, only the child ticket may be checked so that it can be left without any problem when accompanied by an adult holding an adult ticket No. registered in the related number. At this time, since there is a possibility that children are coming to play, only when accompanied by a person holding an adult ticket at the time of ticket purchase, check the adult ticket with the related number registered when leaving It may be.

  As described above, according to the safety maintenance system according to the present embodiment, even when the companion cannot be identified when entering the predetermined area, the relationship is based on the movement information in the predetermined area. It is possible to accurately perform grouping of accompanying persons having sex.

In addition, accurate grouping can be performed based on the location of movement, the number of times of movement, the order of passage during movement, and / or the presence or absence of a companion having a relationship during movement.
Furthermore, since the degree of association is weighted according to the number of movements, the order of passage, and the presence or absence of a companion, an accurate degree of association can be calculated according to the location and environment of the predetermined area.

In addition, a warning is given when there is no relevant companion at the time of exit, so if a child or woman leaves alone or with an unrelated companion, a removal or kidnapping is detected. Can be prevented.
Furthermore, when an adult and a child enter together and there is no adult companion who has a relationship when the child leaves, a child's safety can be particularly ensured.

  Although the present invention has been described with the above embodiment, the technical scope of the present invention is not limited to the scope described in the embodiment, and various modifications or improvements can be added to the above embodiment.
