The controller 3 is provided on each of a plurality of floors of the building. The controller 3 provided on each floor can communicate with the central management device 4.

  FIG. 2 is a block diagram showing the respective configurations of the card reader 1, the electric lock 2, and the controller 3 of the entry / exit management system according to Embodiment 1 of the present invention.

  2, the card reader 1 includes a reading device 11 and an alarm device 12. The reading device 11 reads and acquires identification information from an IC card (not shown) of a pedestrian passing through the entrance. The IC card holds identification information unique to a passer who owns the IC card. Examples of the identification information include information for identifying a passer-by, information for identifying a department to which the passer belongs, and information for identifying whether a passer is an employee or a visitor. Can be

  The identification information of the passerby read by the reading device 11 is given to the controller 3. The alarm device 12 generates an alarm such as a sound under the control of the controller 3.

  The electric lock 2 includes an electric lock main body 21 and an open state detection device 22. The electric lock body 21 is displaced between a locked position where the door is locked and an unlocked position where the door is unlocked. When the electric lock main body 21 is located at the lock position, the door is locked, and when the electric lock main body 21 is at the unlock position, the door is unlocked. When the door is open, the open state detection device 22 detects that the state of the door is open. The detection result of the open state detection device 22 is given to the controller 3.

  The controller 3 includes, for example, a microcomputer that executes arithmetic processing, a ROM (Read Only Memory) that stores data such as program data and fixed value data, and a RAM (Random) that updates stored data and sequentially rewrites the stored data. Access Memory), a timer, and the like. The controller 3 acquires the identification information read by the reading device 11 from the reading device 11. The controller 3 includes an electric lock control unit 31, an allowable time determination unit 32, an alarm device control unit 33, a passage history information registration unit 34, and an allowable time list update unit 35.

  The electric lock controller 31 uses the identification information read by the reading device 11 to determine whether or not to allow a pedestrian to pass. Specifically, the electric lock control unit 31 holds the identification information of the pedestrian permitted to pass through the entrance as registered identification information. If the identification information read by the reading device 11 matches the registered identification information, the electric lock control unit 31 determines that the passage of a pedestrian is permitted. On the other hand, if the identification information read by the reading device 11 is different from the registered identification information, the electric lock control unit 31 determines that the passage of a passerby is not permitted.

  When the electric lock control unit 31 determines that the passage of a pedestrian is permitted as a result of the above-described determination, the electric lock 2 is unlocked by controlling the electric lock 2. The electric lock control unit 31 controls the electric lock 2 to lock the door when a preset time has elapsed since the door was unlocked. On the other hand, when the electric lock control unit 31 determines that the passage of the pedestrian is not permitted, the electric lock 2 keeps the door locked.

  The allowable time determination unit 32 holds an allowable time list described later. The permissible time determination unit 32 refers to the permissible time list and determines a permissible time that is a time that allows the door to be opened.

  Here, an example of the allowable time list held by the allowable time determining unit 32 will be described with reference to FIG. FIG. 3 is a diagram showing an example of the allowable time list held by the allowable time determining unit 32 in FIG.

  In FIG. 3, the allowable time list is a list in which “identification information” that is information for identifying a pedestrian is associated with “allowable time” that is a time during which the door is allowed to be opened. .

  In FIG. 3, regarding the correspondence between the identification information registered in the allowable time list and the allowable time, the allowable time corresponding to “A” is “30 seconds”, and the allowable time corresponding to “B” is This is an example in which “60 seconds” and the allowable time corresponding to “C” is “75 seconds”.

  The allowable time determination unit 32 determines an allowable time corresponding to the identification information read by the reading device 11 according to the allowable time list.

  When the elapsed time from when the door is unlocked and the door is opened reaches the allowable time determined by the allowable time determination unit 32, the alarm device control unit 33 issues an alarm by controlling the alarm device 12. generate. If the alarm device control unit 33 confirms that the door has been opened based on the detection result of the open state detection device 22, the alarm device control unit 33 starts measuring the time elapsed since the door was opened. The alarm device control unit 33 resets the measured elapsed time if it is confirmed from the detection result of the open state detection device 22 that the door is closed.

  The traffic history information registration unit 34 holds a traffic history information list described later. The passage history information registration unit 34 associates the time at which the door is unlocked and the door is opened, and the time at which the door is opened and then the door is closed with the identification information read by the reading device 11, Register in the traffic history information list. If the passage history information registration unit 34 confirms that the door has been opened from the detection result of the open state detection device 22, it determines the time at which the door was opened. In addition, if the passage history information registration unit 34 confirms that the door has been closed from the detection result of the open state detection device 22, it determines the time at which the door was closed.

  When an alarm is generated by the alarm device 12, the traffic history information registration unit 34 associates the alarm information, which is information indicating that the alarm has been generated, with the identification information read by the reading device 11, Register with. Further, the passage history information registration unit 34 has a function of periodically outputting the passage history information list to the central management device 4.

  Here, an example of the travel history information list held by the travel history information registration unit 34 will be described with reference to FIG. FIG. 4 is a diagram showing an example of a travel history information list held by the travel history information registration unit 34 of FIG.

  In FIG. 4, the passage history information list includes “identification information” that is information for identifying a pedestrian, “door opening and closing time information” that is information indicating a time at which the door is opened and closed, and information that an alarm has been generated. This is a list in which “warning information”, which is information to be displayed, is associated. The door opening / closing time information includes “door opening time” indicating the time when the door was unlocked and the door was opened, and “door closing time” indicating the time when the door was opened and then the door was closed. .

  FIG. 4 exemplifies the correspondence between the identification information, the door opening / closing time information, and the alarm information registered in the passage history information list, as illustrated. For example, the door opening time and the door closing time corresponding to “A” are “9:05:10” and “9:05:18”, respectively. As shown in FIG. 4, the alarm information corresponding to “B” indicates that an alarm has occurred, while the alarm information corresponding to each of “A” and “C” indicates that no alarm has occurred. Is shown.

  The permissible time list updating unit 35 updates the permissible time list held by the permissible time determining unit 32 according to an update command input from the external central management device 4.

  The central management device 4 is configured to be operable by a user. The central management device 4 generates an update command according to the operation of the user, and gives the generated update command to the allowable time list updating unit 35 of the controller 3. The central management device 4 is configured using, for example, a personal computer.

  The central management device 4 periodically acquires and stores the passage history information list stored in the passage history information registration unit 34 from the passage history information registration unit 34. The central management device 4 displays the stored information of the passage history information list on the screen according to the operation of the user. Thereby, the user can confirm the information of the passage history information list.

  After confirming the information of the passage history information list displayed on the screen by the central management device 4, the user operates the central management device 4 to change the allowable time of the allowable time list from the central management device 4 side. Is given to the permissible time list updating unit 35. Thereby, the user can arbitrarily change the allowable time corresponding to each piece of identification information in the allowable time list.

  For example, it is assumed that the user refers to the warning information in the traffic history information list illustrated in FIG. 4 and confirms that the passer corresponding to the identification information “B” has generated a warning. In this case, since it takes time for the passerby corresponding to "B" to pass through the door, the user needs to increase the allowable time corresponding to "B" so as not to generate an alarm. Judgment is conceivable.

  In the case described above, the user operates the central management device 4 in order to make the allowable time corresponding to “B” longer than 60 seconds in the allowable time list illustrated in FIG. The user operates the central management apparatus 4 to change the allowable time corresponding to “B” in the allowable time list from 60 seconds to a time longer than 60 seconds (for example, 75 seconds) from the central management apparatus 4 side. An update command for changing is given to the allowable time list updating unit 35. In this case, the allowable time list updating unit 35 updates the allowable time corresponding to “B” in the allowable time list from 60 seconds to a time longer than 60 seconds according to the update command. Accordingly, when the identification information read by the reading device 11 is “B”, the allowable time determined by the allowable time determining unit 32 is longer than 60 seconds.

  In step S102, the electric lock control unit 31 unlocks the door by controlling the electric lock 2. Thereafter, the process proceeds to step S103.

  In step S103, the allowable time determination unit 32 determines the allowable time corresponding to the identification information acquired from the reading device 11 according to the allowable time list. Thereafter, the process proceeds to step S104.

  In step S104, the alarm device control unit 33 determines whether the door has been opened based on the detection result of the open state detection device 22. If it is determined that the door has been opened, the process proceeds to step S105. If it is determined that the door has not been opened, step S104 is executed again.

  In step S105, the alarm device control unit 33 determines whether or not the elapsed time since opening of the door has reached the allowable time determined in step S103. If it is determined that the elapsed time has reached the allowable time, the process proceeds to step S108; if it is determined that the elapsed time has not reached the allowable time, the process proceeds to step S106.

  In step S106, the alarm device control unit 33 determines whether or not the door has been closed based on the detection result of the open state detection device 22. If it is determined that the door is closed, the process proceeds to step S107; if it is determined that the door is not closed, the process returns to step S105.

  In step S107, the passage history information registration unit 34 registers the door opening time and the door closing time constituting the door opening and closing time information in the passage history information list in association with the identification information acquired from the reading device 11. Thereafter, the process ends. After the processing in step S107, the electric lock control unit 31 locks the door by controlling the electric lock 2.

  In step S108, the alarm device control unit 33 generates an alarm by controlling the alarm device 12. Thereafter, the process proceeds to step S109.

  In step S109, the alarm device control unit 33 determines whether or not the door has been closed based on the detection result of the open state detection device 22. If it is determined that the door is closed, the process proceeds to step S110, and if it is determined that the door is not closed, the process returns to step S108.

  In step S110, the passage history information registration unit 34 stores the door opening time and the door closing time, which constitute the door opening and closing time information, and the alarm information in association with the identification information acquired from the reading device 11 in the passage history information list. Register with. Thereafter, the process ends. After the process in step S110, the electric lock control unit 31 locks the door by controlling the electric lock 2.

On the other hand, in the second embodiment, the allowable time list updating unit 35 is configured to update the allowable time list with reference to the traffic history information list held by the traffic history information registration unit 34. ing.

  FIG. 6 is a block diagram showing respective configurations of the card reader 1, the electric lock 2, and the controller 3 of the entry / exit management system according to Embodiment 2 of the present invention.

  In FIG. 6, for example, the allowable time list updating unit 35 refers to the alarm information in the passage history information list illustrated in FIG. 4, and the passer corresponding to the identification information “B” has generated an alarm. After confirming this, the following operation is performed. That is, the permissible time list updating unit 35 extends the permissible time corresponding to “B” in the permissible time list by 60 seconds by a preset time (for example, 15 seconds), thereby changing the “permissible time list” to “ The allowable time corresponding to “B” is updated from 60 seconds to a time longer than 60 seconds.

  Further, for example, the allowable time list update unit 35 determines the optimum allowable time for each piece of identification information with reference to the door opening / closing time information in the passage history information list illustrated in FIG. For each piece of information, the already registered allowable time is updated to the determined optimum allowable time.

  As a specific method of determining the optimum allowable time by the allowable time list updating unit 35, for example, the following method can be considered. That is, the permissible time list updating unit 35 calculates the time between the door closing time and the door opening time in the registered chronologically latest door opening / closing time information for each piece of identification information in the passage history information list. . The allowable time list updating unit 35 determines the calculated time as the optimum allowable time for each piece of identification information. Note that the optimum allowable time may be an average value of the time calculated for each registered door opening / closing time information.

  As described above, according to the second embodiment, the entry / exit management system includes the electric lock control unit that unlocks the door when it is determined that the passage of a pedestrian is permitted based on the identification information read by the reading device.

On the other hand, in the third embodiment, in addition to the configuration of the first or second embodiment, the allowable time determination unit 32 further sets the pattern of reading the identification information by the reading If so, the preset time is determined as the allowable time regardless of the allowable time list.

  For example, if the passerby does not want to make the allowable time longer than usual, the passerby performs a normal operation of holding the IC card owned by the passerby once to the card reader 1. When such a normal operation is performed, the reading device 11 of the card reader 1 reads the identification information of the IC card once.

  In the case described above, the allowable time determination unit 32 confirms that the reading pattern of the identification information by the reading device 11 is a normal pattern read once by the reading device 11. When confirming such a normal pattern, the allowable time determination unit 32 determines an allowable time corresponding to the identification information according to the allowable time list, as in the first or second embodiment.

  On the other hand, if the passer-by wants to make the permissible time longer than usual, the passer-by performs a specific operation of holding the IC card owned by the passerby twice over the card reader 1 continuously. When such a specific operation is performed, the reading device 11 of the card reader 1 reads the identification information of the IC card twice consecutively.

  In the case described above, the allowable time determination unit 32 confirms that the reading pattern of the identification information by the reading device 11 is a specific pattern that is continuously read twice by the reading device 11. When confirming such a specific pattern, the allowable time determination unit 32 determines a preset time set as the allowable time without using the allowable time list.

  The above-mentioned set time can be arbitrarily set in the controller 3 by the user. The specific pattern described above may be any pattern as long as it is different from a normal pattern.

  As described above, according to the third embodiment, the entry / exit management system sets in advance the configuration of the first or second embodiment if the pattern of the identification information read by the reader is a specific pattern. It is further configured to determine the set time set as the allowable time. As a result, the same effects as those of the first or second embodiment can be obtained, and furthermore, it is possible to determine the permissible time by a specific operation of the passerby.

  Although the first to third embodiments have been individually described, the configuration examples disclosed in the first to third embodiments can be arbitrarily combined.
