Description

  The present invention relates to an entrance / exit management system and method for managing entrance / exit.

  For example, there is an entrance / exit management system for the purpose of restricting entrance / exit to / from a specific room (passing through an entrance / exit) in order to maintain confidentiality. One of the problems of such an entrance / exit management system is companionship. “Shared” refers to a state where a person who does not have the right to enter the room enters (invades) together with a person who has the right to enter the room. This sharing is an important issue from the viewpoint of confidentiality and security.

  As a technology for detecting companionship, an area in which a user has a portable terminal is detected, and a predetermined amount is set between the detected area information and the travel history information recognized by the entrance / exit system. There is a system for detecting a companion when the relationship is established (see Patent Document 1).

  Also, there is a technique for determining the number of people entering a room by tracking the moving direction of a person photographed by an imaging means, and determining that more than a predetermined number of persons are accompanied after authentication (Patent Document 2). reference).

  Further, the entrance / exit management method according to the present invention includes a first step of accepting authentication information and a pressure application detected by a pressure detection mat that two-dimensionally detects a pressure applied by being installed on one side of the entrance / exit. A second step of determining a human footprint from the shape of the region; a third step of determining a pair of left and right footprints from the shape of a plurality of pressure application regions determined to be footprints; Corresponding to the fourth step for obtaining the number of persons on the pressure detection mat from the number of pairs determined to be a pair of left and right pairs, authentication information and the obtained number of persons, authentication permission information stored in advance, and this authentication permission information A fifth step of performing authentication by comparing the number of authorized persons to be authenticated. Note that at least a sixth step of controlling the opening and closing of the entrance door according to the result of authentication is provided.

  As described above, according to the present invention, it is determined as a pair of left and right foot shapes from the shape of a plurality of pressure application regions determined to be human footprints from the shape of the pressure application region detected by the pressure detection mat. The number of persons on the pressure detection mat is obtained from the number of the set, and authentication is performed by comparing the authentication information and the obtained number of persons with the authentication permission information stored in advance and the number of authorized persons corresponding to the authentication information. did. As a result, it is possible to obtain an excellent effect that it is possible to make a companion decision before entering the room.

It is a block diagram which shows the structure of the entrance / exit management system in embodiment of this invention. It is the top view which showed the state by which the pressure detection mat | matte is laid. It is a flowchart for demonstrating the entrance / exit management method in embodiment of this invention.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram showing a configuration of an entrance / exit management system in an embodiment of the present invention. This system first includes an authentication information receiving unit 101 disposed on one side of the inlet / outlet and a pressure detection mat 102 that is laid on one side of the inlet / outlet and detects the applied pressure two-dimensionally. Prepare. For example, the pressure detection mat 102 is configured by two-dimensionally arranging a plurality of pressure sensitive elements.

  In addition, the present system includes a foot shape determination unit 103 that determines a human footprint from the shape of the pressure application region detected by the pressure detection mat 102, and a plurality of pressure application regions that the foot shape determination unit 103 has determined to be a footprint. The combination determination unit 104 that determines a pair of left and right foot shapes from the shape of the shape, and the number of pairs on the pressure detection mat 102 that is determined by the combination determination unit 104 as a pair of left and right foot shapes. And a desired number counting unit 105.

  In addition, this system stores the number of people obtained by the number counting unit 105 when the authentication information receiving unit 101 receives the authentication information, the authentication information received by the authentication information receiving unit 101, and the authentication information storage unit 108. And a traffic authentication unit 106 that performs authentication by comparing the authentication permission information and the number of authorized persons corresponding to the authentication permission information. When a door is provided at the entrance / exit, an opening / closing control unit 107 that controls the opening / closing of the entrance / exit door according to the authentication result of the traffic authentication unit 106 may be provided.

  For example, as shown in the schematic plan view of FIG. 2, the authentication information receiving unit 101 and the pressure detection mat 102 are laid on the side of a corridor 211 partitioned by a door 201 and a wall 202 provided at an entrance / exit. Yes. For example, the authentication information receiving unit 101 is installed on the wall 202 adjacent to the door 201 on the side of the hallway 211. On the other hand, the pressure detection mat 102 is laid on the floor of the hallway 211, for example.

  Moreover, the opening / closing control part 107 is attached to the room 212 side of the door 201 and is, for example, an electric lock. The pressure detection mat 102 is laid in front of the door 201 on the corridor 211 side. In the case of these configurations, the entrance / exit management system in the present embodiment is applied to entrance management, and a person who tries to enter the room 212 through the door 201 steps on the pressure detection mat 102.

  The pressure detection mat 102 that has been stepped on in this manner two-dimensionally detects the pressure applied by the foot (footwear) and detects a pressure application region corresponding to the shape of the foot. The foot shape determination unit 103 determines that the shape of the pressure application area detected by the pressure detection mat 102 is a human footprint by, for example, pattern matching based on comparison with a preset shape. Moreover, the shape of the pressure application area when applied by a cane or the like can also be determined by pattern matching.

  Also, the combination determination unit 104 determines the right foot and the left foot from the shape of the footprint, for example, by pattern matching similar to the above. Further, the combination determination unit 104 determines the pair of left and right foot forms of the same person by comparing the shapes of the determined right foot and left foot. For example, by identifying a pair of footprints that are line-symmetric within a set error range, a pair of footprints that are the left and right pairs of the same person is determined. Further, when the foot shape determination unit 103 determines that the shape of the pressure application region is that of a cane, it may be determined as a set based on the distance between the footprint and the mark of the cane.

  If a pair of left and right footprints is identified as described above, this can be a single person. As a result, the number counting unit 105 obtains the number of persons on the pressure detection mat 102 from the number of pairs determined as a pair of left and right footprints. For example, if two pairs of left and right footprints are identified at the same time, the number counting unit 105 determines that two people are present on the pressure detection mat 102 at this time. To do. For example, if three pairs of left and right footprints are identified at the same time, at this time, the person counting unit 105 has three persons on the pressure detection mat 102. Judge.

  As described above, when the authentication information receiving unit 101 receives the authentication information while the number counting unit 105 is counting the number of people existing on the pressure detection mat 102, the number of people counted at this point The traffic authentication unit 106 performs authentication based on the received authentication information. In the authentication information storage unit 108, authentication permission information and the number of authorized persons corresponding to the authentication permission information are stored in advance. For example, the authentication permission information A is associated with the number of authorized persons indicating that one person is permitted and stored in the authentication information storage unit 108.

  The traffic authentication unit 106 first checks whether or not there is a match with the authentication information received by the authentication information receiving unit 101 among the plurality of authentication permission information stored in the authentication information storage unit 108. When the authentication permission information that matches the authentication information storage unit 108 is stored, the traffic authentication unit 106 includes the number of authentication permitted persons associated with the matching authentication permission information, the number of persons counted by the person counting unit 105, and Compare In this comparison, when the number of authorized persons coincides with the counted number of persons, the traffic authentication unit 106 assumes that the authentication has been performed, and opens the opening / closing control unit 107. When the opening / closing control unit 107 is opened, the door 201 (FIG. 2) can be opened.

  On the other hand, when the number of authorized persons associated with the authentication permission information that matches the accepted authentication information does not match the number of persons counted by the number of persons counting unit 105, the passage authentication unit 106 determines that the authentication is not established and opens / closes control The closed state in the unit 107 is maintained. For example, even if the number of authorized persons associated with the authentication permission information is one, if the number of persons counting unit 105 counts two, the passage authentication part 106 determines that the authentication is not established. This state is a so-called companion where there are two persons on the pressure detection mat 102 and these two persons are going to enter the room.

  In this case, even if the person who intends to enter the room inputs correct authentication information to the authentication information receiving unit 101, the person cannot enter the door 201 and cannot pass through the entrance / exit where the door 201 is disposed. According to the entrance / exit management system of the present embodiment described above, it is possible to determine the accompanying state before passing through the entrance / exit such as entering the room, and it is possible to prevent the entrance / exit from passing due to accompanying. In addition, this system performs entrance / exit passage management, and can be applied not only to entry but also to exit management. In the above description, the door is opened and closed by the opening and closing control unit 107, but the present invention is not limited to this. For example, the present invention can be applied to an entrance / exit without a door. In such a case, for example, the traffic authentication unit 106 may notify the administrator who manages the result of the authentication. In addition, the result of authentication can be notified to the target person by voice or buzzer sound.

  Next, the operation (entrance / exit management method) of the entrance / exit management system in the present embodiment will be described. First, in step S301, the authentication information reception unit 101 waits for reception of authentication information. When the authentication information reception unit 101 receives the authentication information (Y in step S301), the foot shape determination unit 103 determines that the footprint is a human footprint from the shape of the pressure application area detected by the pressure detection mat 102 (step S302). ).

  Next, in step S303, the combination determination unit 104 determines a pair of left and right footprints from the shape of the plurality of pressure application regions determined to be footprints by the footprint determination unit 103. Next, in step S <b> 304, the number counting unit 105 obtains the number of people on the pressure detection mat 102 based on the number of pairs determined to be a pair of left and right feet by the combination determining unit 104.

  Next, in step S305, the traffic authentication unit 106 compares the received authentication information and the counted number of persons with the authentication permission information stored in the authentication information storage unit 108 and the corresponding authentication permitted number of persons. Authenticate with Here, when authentication is performed (Y in step S305), the traffic authentication unit 106 opens, for example, the open / close control unit 107 (step S306). On the other hand, when the authentication is not performed (N in step S305), the open / close control unit 107 is not opened but is kept closed, and the process ends.

  If the authentication is not established, the subject person may be notified of the inability to pass by voice, buzzer, light emission display, or the like. The above-described opening / closing control is performed when a door is provided at the entrance / exit. Therefore, when there is no door at the entrance / exit, the opening / closing control is not performed. If there is no door, the result of authentication may be notified to the administrator who performs management. Further, even when there is no door, if authentication is not established, the subject person may be notified by voice, buzzer, light-emitting display, etc.
