[Background technology]

[0002] Patent Document 1 describes a card reading device having a card, a specification switching means, an intrusion monitoring verification means, and a main control means. The card stores individual ID information of people permitted to enter and exit a room in the entry / exit control device specification, and stores information indicating this in the intrusion monitoring device specification. The reading means reads the information stored on the card. The specification switching means manually switches between the entry / exit control device specification and the intrusion monitoring device specification. Information indicating the intrusion monitoring specification is pre-stored in memory, and the intrusion monitoring verification means compares the information read by the reading means with the information stored in the memory and, if they match, outputs information to set or cancel the intrusion monitoring status. The main control means outputs the information read by the reading means as is when the entry / exit control device specification is set by the specification switching means, and outputs information to set or cancel the intrusion monitoring status from the intrusion monitoring control means when the intrusion monitoring device specification is set.

[0012] (1) Overview First, an overview of an access control system 1 according to an embodiment of the present disclosure will be described with reference to FIG.

[0013] As shown in FIG. 1, the entrance / exit control system 1 is a system that controls entrance / exit to a first area A11 within a predetermined area A1.

[0014] Entrance and exit refers to a person entering and exiting an area. Entrance and exit to the first area A11 refers to a person entering the first area A11 and a person exiting the area A11.

[0015] The "people" referred to here, that is, people who enter and exit the first area A11, are users who use the first area A11. A user who uses the first area A11 is, for example, an employee of a company who performs business in the predetermined area A1. The predetermined area A1 is the inside of a company building (hereinafter, may be referred to as "indoors"). The first area A11 is the inside of a room (hereinafter, may be referred to as "room") of the department to which the employee belongs.

[0016] In this embodiment, the predetermined area A1 includes a first area A11 (for example, an indoor area) that is a part of the predetermined area A1, and a second area A12 outside the first area A11. The second area A12 is, for example, an area that is both indoors and outdoors, such as a passageway or an entrance.

[0017] More specifically, the entrance / exit control system 1 includes an acquisition unit 122, an output unit 13, and a first control unit 123, as shown in FIG.

[0018] (1-1) Acquisition section The acquisition unit 122 acquires first entrance / exit information. The first entrance / exit information is information relating to people's entry into and exit from the first area A11. The first entrance / exit information includes a user ID and first group information.

[0019] The user ID is information that identifies a user. The first set of information is a set of time information and an entry / exit flag. The time information is information related to the time of entry / exit. The time information is, for example, information indicating the time when the user's entry into the first area A11 is detected (entry time), or the time when the user's exit from the first area A11 is detected (exit time). The entry / exit flag is information related to the type of entry / exit. The entry / exit flag is, for example, information indicating "entry" or "exit".

[0020] The acquisition unit 122 acquires the first entry / exit information in response to, for example, a person's entry into or exit from the first area A11. The entry / exit of a person into or from the first area A11 is detected based on, for example, the position and change in position of the mobile terminal 101 carried by the person.

[0021] Details will be described later, but in this embodiment, the management unit 121 generates first entry / exit information in accordance with people entering and exiting the first area A11, and the acquisition unit 122 acquires the first entry / exit information generated by the management unit 121.

[0022] (1-2) Output section The output unit 13 outputs various types of information.

[0023] The various types of information include, for example, alert setting information, notification information, confirmation information, and notification information (all of which will be described later), etc. The output unit 13 outputs the information such as alert setting information acquired by the acquisition unit 122 under the control of the first control unit 123.

[0024] The output of the output unit 13 is basically audio output from a speaker. The speaker is, for example, a speaker provided in the access control system 1, but may also be a speaker provided in the operation terminal 2 or a speaker provided in the access control system 1.

[0025] The audio output from the speaker of the operation terminal 2 is realized, for example, by the output unit 13 transmitting information to the mobile terminal 101 via the communication unit 14 and a communication medium 200 (described later). In this case, in the operation terminal 2, the communication unit 23 receives information from the access control system 1, and the notification unit 22 outputs the information via the speaker of the operation terminal 2.

[0026] Audio output from the speaker of the mobile terminal 101 is realized, for example, by the output unit 13 transmitting information to the mobile terminal 101 by short-range wireless communication via the communication unit 14. In this case, the mobile terminal 101 receives information from the access control system 1 and outputs the information as audio via the speaker of the mobile terminal 101.

[0027] However, the output of the output unit 13 may be displayed on a display, for example. The display may be a display provided in the entry / exit control system 1, but may also be a display of the mobile terminal 101 or a display of the operation terminal 2.

[0028] (1-3) First control section The first control unit 123 causes the output unit 13 to output alert setting information when a first condition is satisfied regarding the exit of the last exiting person 10 from the first area A11 based on the first entry / exit information acquired by the acquisition unit 122.

[0029] (1-3-1) Last person to leave The last exiting person 10 is the last person to exit the first area A11 among one or more people (occupants) who were present in the first area A11 (for example, a room).

[0030] A person who has left the first area A11, that is, an exiting person, is a person who has moved from the first area A11 to a second area A12 (for example, an indoor passageway or entrance) outside the first area A11.

[0031] The last person 10 to leave the first area A11, that is, the last person to leave the first area A11 and move to the second area A12, basically moves further from the second area A12 to the outside of the perimeter of the second area A12, that is, outside the predetermined area A1 (for example, exits outdoors). However, the last person to leave the first area A11 and move to the second area A12 may re-enter the first area A11 without leaving the second area A12 to the outside of the predetermined area A1.

[0032] (1-3-2) Alert setting information The alert setting information is information for setting alert for the first area A11.

[0033] The alert setting for the first area A11 is a setting for increasing the level of alert against an intrusion by an intruder into the first area A11. The alert setting for the first area A11 is performed in response to a human operation or automatically.

[0034] Setting up an alert includes cases where the access control system 1 sets up an alert in response to human operation (manual alert setting), and cases where the access control system 1 automatically sets up an alert (automatic alert setting).

[0035] The alert setting information is basically information that allows the last exiting person 10 to manually set alert settings for the first area A11 via the access control system 1. The alert setting information is, for example, information such as "You are the last exiting person. Do you want to set alert settings?"

[0036] (1-3-3) First condition judgment The first control unit 123 performs a first condition determination. The first condition determination is to determine whether or not a first condition is satisfied based on one or more pieces of history information and number of people information (both of which will be described later) managed by the management unit 121 (described later).

[0037] (1-3-3a) First condition The first condition is a condition for manually setting an alert, and includes a condition that it is determined that the last exiting person 10 has exited the first area A11 (basic condition: described later).

[0038] (1-4) Advantages According to the above-described configuration of this embodiment, when the first condition is met regarding the exit of the last exiting person 10 from the first area A11, alert setting information is output, thereby assisting in manually setting alert settings for the first area A11 and ultimately improving security.

[0039] Furthermore, since the first condition includes the exit of the last exiting person 10 from the first area A11, alert setting information is output when the last exiting person 10 exits the first area A11. Based on the output alert setting information, alert setting for the first area A11 is manually performed, thereby improving security.

[0040] (2) Other important parts Next, other main parts of the entry / exit control system 1, that is, main parts other than the acquisition unit 122, the output unit 13, and the first control unit 123 described in "(1) Overview", will be described.

[0041] (2-1) Second control section The entrance / exit control system 1 further includes a second control unit 124, as shown in FIG.

[0042] The second control unit 124 executes the alert setting. The second control unit 124 executes the alert setting in response to a human operation or automatically.

[0043] (2-1-1) Notification Information The alert setting information that the first control unit 123 causes the output unit 13 to output includes alarm information.

[0044] The notification information is information for notifying a person (for example, a user carrying the mobile terminal 101). The notification information in this embodiment is information for guiding the last exiting person 10 to perform an alert setting operation.

[0045] (2-1-2) Warning setting operation The alert setting operation is an operation for causing the second control unit 124 to execute alert setting.

[0046] The notification information may be, for example, "You are the last person to leave. Please perform the alert setting operation (press the 'Execute' button)."

[0047] According to this aspect, since the alert setting information includes the notification information, it is possible to guide the last person 10 to leave the first area A11 so that they can perform an alert setting operation for the first area A11. By having the last person 10 perform an alert setting operation in response to the guidance, it is possible to manually and accurately set alerts, thereby further improving security.

[0048] The alert setting operation is an operation indicating whether or not the alert setting is to be executed, that is, whether or not the alert setting is to be executed (whether or not to be executed).

[0049] The security setting operation in this embodiment is the operation of pressing the "Execute" button, which indicates that security setting is to be executed (that security setting is to be executed).

[0050] (2-1-3) Confirmation information The notification information includes confirmation information, which is information for confirming with the last exiting person 10 whether or not the alert setting is being executed.

[0051] In this embodiment, the confirmation information is, for example, "You are the last person to leave. Do you want to execute the security settings? If you want to execute the security settings, please press the execute button. If you do not want to execute the security settings, please press the cancel button."

[0052] In this way, since the notification information includes confirmation information, it becomes possible to confirm with the last exiting person 10 whether or not an alert setting has been implemented for the first area A11. For example, if the last exiting person 10 confirms that an alert setting has been implemented for the first area A11, the second control unit 124 implements the alert setting. This allows the last exiting person 10 to manually and appropriately implement alert setting, thereby further improving security.

[0053] Furthermore, if the last exiting person 10 confirms that the alert setting for the first area A11 has not been implemented, the second control unit 124 does not implement the alert setting. This makes it possible to avoid unnecessary implementation of the alert setting if a person is present in the first area A11 after the exit of the last exiting person 10 is detected, that is, if a false detection of the last exiting person 10 occurs.

[0054] (2-1-4) Alert settings after confirming execution The second control unit 124 executes the security setting when it confirms that the security setting has been executed as a result of the security setting operation being performed by the last exiting person 10. The second control unit 124 executes the security setting when it confirms that the security setting has been executed, for example, when the "Execute" button is pressed.

[0055] By performing this type of security setting operation by the last person to exit, it is confirmed that the security setting has been implemented, and then the security setting is implemented, thereby enabling accurate manual security setting and further improving security.

[0056] (2-2) Management Department The entrance / exit control system 1 further includes a management unit 121 as shown in FIG.

[0057] (2-2-1) Entrance / exit management The management unit 121 performs entrance / exit management. The entrance / exit management is management of entrance / exit to the predetermined area A1. The entrance / exit to the predetermined area A1 is the movement of people across the second boundary AL2 as shown in FIG.

[0058] The above-mentioned entry and exit into the first area A11 refers to the movement of people across the first boundary AL1 as shown in FIG.

[0059] (2-2-1a) First and second boundaries The first boundary AL1 is the boundary between the first area A11 and the second area A12. The first area AL1 is, for example, a wall of a room, and in particular, an opening formed in the wall. For example, a door is provided at the first boundary AL1 (opening).

[0060] The second boundary AL2 is the boundary between the predetermined area A1 and the outside of the predetermined area A1.

[0061] As described above, the second area A12 is an area within the predetermined area A1 that is outside the first area A11. The second boundary AL2 is, for example, an outer wall of a company building, and in particular, an opening formed in the outer wall. The second area A12 (opening) is provided with, for example, an automatic door.

[0062] The outside of the second boundary AL2 is the outer surface of the exterior wall or the vicinity of the outer surface. The vicinity of the outer surface is, for example, the periphery of an automatic door.

[0063] (2-2-1b) Entry and exit to designated areas Entry and exit of a person into the predetermined area A1 includes at least one of a person entering the predetermined area A1 and a person exiting from the predetermined area A1. A person entering the predetermined area A1 is a person moving from outside the predetermined area A1 to inside the predetermined area A1. A person exiting from the predetermined area A1 is a person moving from inside the predetermined area A1 to outside the predetermined area A1.

[0064] 1, the predetermined area A1 in this embodiment is made up of a first area A11 and a second area A12 outside the first area A11. Therefore, in this embodiment, the second boundary AL2 is located on the outer periphery of the second area A12.

[0065] Therefore, entry and exit of a person into the predetermined area A1 is the movement of a person across the second boundary AL2 on the periphery of the second area A12. Furthermore, entry of a person into the predetermined area A1 is the movement of a person from outside the periphery of the second area A12 to inside the second area A12, crossing the second boundary AL2 on the periphery of the second area A12. Furthermore, exit of a person from the inside of the second area A12 is the movement of a person from outside the periphery of the second area A12 to outside the periphery of the second area A12, crossing the second boundary AL2 on the periphery of the second area A12.

[0066] The entrance / exit management includes entrance / exit detection, history management, and number of people management.

[0067] (2-2-1c) Entry / Exit Detection The entry / exit detection is the detection of entry and exit to / from the predetermined area A1, and includes the detection of each of a person entering the predetermined area A11 and a person exiting the predetermined area A1.

[0068] Entry and exit to the specified area A1, that is, the entry of a person into the specified area A1 and the exit of a person from the specified area A1, are detected based on short-range wireless communication between the mobile terminal 101 and at least one of the entry / exit management system 1 and the operation terminal 2 (in this embodiment, each of the entry / exit management system 1 and the operation terminal 2).

[0069] 1, the access control system 1 of this embodiment is provided inside the second area A12. The operation terminal 2 of this embodiment is provided outside the second boundary AL2 between the predetermined area A1 and the outside of the predetermined area A1, that is, outside the periphery of the second area A12 that surrounds the first area A11. Therefore, in this embodiment, entry and exit to the predetermined area A1 is detected based on short-range wireless communication between the mobile terminal 101 and each of the access control system 1 and the operation terminal 2.

[0070] For example, location information (described later) of the mobile terminal 101 is acquired using received signal strength indicator (RSSI) of a signal transmitted and received via short-range wireless communication between the mobile terminal 101 carried by the user and the access control system 1. Furthermore, location change information (described later) of the mobile terminal 101 is acquired based on multiple pieces of location information acquired at different times.

[0071] Based on the position information and position change information thus acquired, the management unit 121 detects each of the user's entry into the predetermined area A1 and the user's exit from the predetermined area A1.

[0072] (2-2-1cA) Obtaining a user ID The entry / exit detection further includes acquiring a user ID that identifies a user whose entry / exit into the predetermined area A1 has been detected as described above (that is, authenticating the user).

[0073] The user ID is stored in advance in the memory of the mobile terminal 101 carried by the user. The user ID is, for example, a telephone number assigned to the mobile terminal 101, but it may also be an email address or employee ID assigned to the user, or any other information that can identify the user.

[0074] The management unit 121 acquires (receives) a user ID from the mobile terminal 101 carried by a user who has detected entry or exit to the specified area A1, for example, by performing at least one of short-range wireless communication via the communication unit 14 and NFC (Near field communication) via the reception unit 11.

[0075] (2-2-1cB) Acquisition of group information The entry / exit detection further includes obtaining group information that is a group of time information and an entry / exit flag.

[0076] In response to detection of entry or exit to the predetermined area A1, the management unit 121 obtains time information indicating the entry time or exit time, for example, by reading the current time from a built-in clock of the processor of the entry / exit management system 1.

[0077] In addition, based on the acquired location information and location change information, the management unit 121 determines whether the detected entry / exit is an entry into the specified area A1 or an exit from the specified area A1, and acquires an entry / exit flag indicating the determination result (for example, "entry" or "exit").

[0078] As a result, in response to detection of entry and exit to the predetermined area A1, group information, which is a group of time information and an entry and exit flag, is acquired.

[0079] (2-2-1d) History Management History management is the management of the history of entry and exit to the predetermined area A1. History management includes storing acquired group information (i.e., a log of entry and exit to the predetermined area A1) for each of one or more users who entered and exited the predetermined area A1.

[0080] When the management unit 121 detects that a user has entered or left the first area A11, it acquires group information and adds the acquired group information to history information corresponding to the user who entered or left the predetermined area A1.

[0081] (2-2-1e) Number of people management Headcount management is management of the number of people in the predetermined area A1. Headcount management involves, for example, calculating the number of people present in the predetermined area A1 and acquiring headcount information indicating the calculation result.

[0082] The management unit 121 updates the number of people information when it detects a user entering or exiting the predetermined area A1. For example, if the detected entry or exit is an entry into the predetermined area A1, "1" is added to the number of people information. Also, if the detected entry or exit is an exit from the predetermined area A1, "1" is subtracted from the number of people information.

[0083] (2-2-2) Entrance / Exit Control for the First Area: First Entrance / Exit Control As shown in FIG. 1, the predetermined area A1 is made up of a first area A11 and a second area A12 outside the first area A11.

[0084] The management unit 121 further performs first entry / exit management. The first entry / exit management is management of entry and exit to the first area A11. The first entry / exit management includes first entry / exit detection, first history management, and first number of people management.

[0085] (2-2-2a) First entry / exit detection The first entry / exit detection is the detection of entry / exit to the first area A11. The first entry / exit detection includes detecting each of a person entering the first area A11 and a person exiting from the first area A11. The entry of a person into the first area A11 is the movement of a person from a second area A12 outside the first area A11 to the first area A11 (for example, entering a room from a corridor). The exit of a person from the first area A11 is the movement of a person from the first area A11 to the second area A12 (for example, exiting from a room to the corridor).

[0086] Entry and exit to the first area A11, that is, the entry of a person into the first area A11 and the exit of a person from the first area A11, are detected based on short-range wireless communication between the mobile terminal 101 and at least one of the entry and exit management system 1 and the operation terminal 2 (in this embodiment, the entry and exit management system 1).

[0087] In detail, as shown in FIG. 1, the access control system 1 and the operation terminal 2 in this embodiment are respectively provided inside and outside the second area A12, and therefore the location information and location change information of the mobile terminal 101 carried by the user are obtained using the RSSI of the signal transmitted and received via short-range wireless communication between the mobile terminal 101 and the access control system 1.

[0088] The management unit 121 detects the entry of a person into the first area A11 and the exit of a person from the first area A11 based on the position information and position change information thus acquired.

[0089] (2-2-2aA) Obtaining user ID In addition, the management unit 121 acquires a user ID from the mobile terminal 101 carried by a user who has been detected as having entered or exited the first area A11, for example, by performing at least one of short-range wireless communication via the communication unit 14 and NFC via the reception unit 11.

[0090] (2-2-2aB) Acquisition of Group 1 information Furthermore, the management unit 121 further acquires a first set of information. The first set of information is a set of time information and an entry / exit flag. That is, in response to detection of entry / exit to the first area A11, the management unit 121 reads the current time from the built-in clock of the entry / exit management system 1 and acquires time information indicating the entry time or the exit time. Furthermore, based on the acquired position information and position change information, the management unit 121 determines whether the detected entry / exit is an entry into the first area A11 or an exit from the first area A11, and acquires an entry / exit flag indicating the determination result (for example, "entry" or "exit").

[0091] (2-2-2b) First History Management The first history management is management of the history of entry and exit to the first area A11. The first history management includes storing the acquired first group information (i.e., the log of entry and exit to the first area A11) for each of one or more users who entered and exited the first area A11.

[0092] When the management unit 121 detects a user entering or exiting the first area A11, it acquires first group information and adds the acquired first group information to the first history information corresponding to the user who entered or exited the first area A11.

[0093] (2-2-2c) First person management The first number-of-people management is management of the number of people related to the first area A11. The first number-of-people management is, for example, calculating the number of people present in the first area A11 and acquiring first number-of-people information indicating the calculation result.

[0094] When the management unit 121 detects a user entering or exiting the first area A11, it updates the first number-of-people information. For example, if the detected entry or exit is an entry into the first area A11, "1" is added to the first number-of-people information. Also, if the detected entry or exit is an exit from the first area A11, "1" is subtracted from the first number-of-people information.

[0095] (2-2-2d) First method of access control The first entry / exit management is realized, for example, as follows.

[0096] (2-2-2dA) Generation of first entrance / exit information The management unit 121 generates first entry / exit information based on the result of the first entry / exit management. The first entry / exit information is entry / exit information related to the first area A11. The first entry / exit information is the entry / exit information explained in "(1-1) Acquisition unit."

[0097] (2-2-2dB) Acquisition of user ID and first set of information The first entry / exit information includes a user ID and first group information. The user ID included in the first entry / exit information is information for identifying a user who has entered or exited the first area A11.

[0098] The time information included in the first group information is information indicating the current time at the time when entry into and exit from the first area A11 are detected. Specifically, the time information included in the first group information is information indicating either the time when entry into the first area A11 is detected (entry time) or the time when exit from the first area A11 is detected (exit time).

[0099] The entry / exit flag included in the first set of information is information indicating, for example, "entry" or "exit."

[0100] Specifically, when the position indicated by the position information (i.e., the user's position) is a position inside the first area A11 and the position change indicated by the position change information (i.e., the moving direction of the mobile terminal 101) is a position change (moving direction) toward the first boundary AL1 as shown in Fig. 1, an entry / exit flag indicating "exit" is acquired. On the other hand, when the position indicated by the position information is a position in the second area A12 outside the first area A11 and the position change indicated by the position change information is a position change toward the first boundary AL1, an entry / exit flag indicating "entry" is acquired.

[0101] (2-2-2dC) Example of the first entrance / exit information The first entry / exit information is generated in response to the detection of each of entry into the first area A11 and exit from the first area A11. The first entry / exit information generated in response to entry into the first area A11 includes a user ID, time information indicating the entry time, and an entry / exit flag indicating "entry." The entry / exit information generated in response to the detection of exit from the first area A11 includes a user ID, time information indicating the exit time, and an entry / exit flag indicating "exit."

[0102] (2-2-2dE) Specific examples of first history information and first number of people information For example, the memory of the entry / exit management system 1 stores one or more user IDs corresponding to one or more users, one or more first history information corresponding to the one or more user IDs, and first number of people information.

[0103] The first history information is information relating to the history of entry and exit to the first area A11. The first history information is, for example, a collection of group information (groups of time information and entry and exit flags) relating to entry and exit to the first area A11.

[0104] The first number-of-people information is information indicating the number of people (occupants) currently present in the first area A11. The initial value of the first number-of-people information is "0."

[0105] (2-2-2dF) Generation of first entry / exit information, and update of first history information and first number of people information When there is entry or exit to the first area A11, the management unit 121 performs the following process: That is, the management unit 121 generates first entry / exit information including the user ID and the first set information, and stores the generated first entry / exit information in memory.

[0106] Furthermore, the management unit 121 updates the first history information corresponding to the user ID included in the generated first entry / exit information, among the one or more pieces of first history information stored in memory in association with one or more user IDs, using the first set of information included in the generated first entry / exit information. In detail, the first set of information corresponding to the user ID included in the acquired first entry / exit information is added to the first history information corresponding to the user ID included in the acquired first entry / exit information.

[0107] Furthermore, the management unit 121 updates the first number of people information stored in memory using the generated first entry / exit information. Specifically, when entry into the first area A11 is detected, "1" is added to the first number of people information. Also, when exit from the first area A11 is detected, "1" is subtracted from the first number of people information.

[0108] (2-3) Details of the first condition The first condition includes the basic condition, and preferably further includes at least one additional condition from among the first to third additional conditions.

[0109] The first condition in this embodiment includes the basic condition and all of the first to third additional conditions.

[0110] (2-3-1) Basic conditions The basic condition is the condition described in "(1-3-3a) First condition", that is, "it is determined that the last exiting person 10 has exited the first area A11."

[0111] The basic condition is, for example, a determination of Yes in step S41 in the flowchart of Fig. 3. If the basic condition is not met (if a determination of No in step S41 is made), the alert setting information is not output (step S46).

[0112] (2-3-2) First Additional Condition The first additional condition is that "it is determined that the last exiting person 10 has exited the second area A12." As described above, the second area A12 is an area within the predetermined area A1 that is outside the first area A11.

[0113] The first additional condition is, for example, a determination of Yes in step S43 in the flowchart of Fig. 3. If the first additional condition is not met (if a determination of No in step S43 is made), the alert setting information is not output (step S46).

[0114] Since the first condition further includes the first additional condition, when the last exiting person 10 who has exited from the first area A11 to the second area A12 leaves the second area A12, the first control unit 123 causes the output unit 13 to output alert setting information, thereby enabling the execution of appropriate manual alert settings for the first area A11 and ultimately improving security.

[0115] In addition, if the last person 10 to leave the first area A11 returns to the first area A11 without going outside the second area A12, the alert setting information will not be output, so it is possible to avoid accidentally performing the alert setting operation if the person temporarily leaves the room for a break, etc.

[0116] (2-3-3) Second Additional Condition The second additional condition is that "the exit time of the last person 10 to leave the first area A11 is determined to be within a predetermined time period."

[0117] The predetermined time period is a time period during which there is basically no entry or exit of people to or from the first area A11, and is a time period during which high security is required. The predetermined time period is, for example, nighttime, holidays, etc.

[0118] The second additional condition is, for example, a determination of Yes in step S44 in the flowchart of Fig. 3. If the second additional condition is not met (if a determination of No in step S44) then the alert setting information is not output (step S46).

[0119] By the first condition further including the second additional condition, when the exit time of the last person 10 to leave the first area A11 falls within a specified time period, the first control unit 123 causes the output unit 13 to output alert setting information, thereby improving security in the first area A11 during times when high security is required, such as at night or on holidays.

[0120] In addition, if the exit time of the last person 10 to leave the first area A11 is outside the specified time period, the alert setting information is not output, so it is possible to avoid the alert setting operation being performed erroneously in response to the output of the alert setting information for the first area A11 during times when there are many people entering and exiting the first area A11, such as during the daytime on a weekday.

[0121] (2-3-4) Third Additional Condition The third additional condition is that "it is determined that the last exiting person 10 has the intention to exit from the first area A11."

[0122] The third additional condition is, for example, a determination of Yes in step S42 in the flowchart of Fig. 3. If the third additional condition is not met (if a determination of No in step S42 is made), the alert setting information is not output (step S46).

[0123] In this embodiment, the determination that the last exiting person 10 has the intention to exit is based on whether an authentication operation has been performed by the last exiting person 10. In other words, when an authentication operation has been performed by the last exiting person 10, the first control unit 123 determines that the last exiting person 10 has the intention to exit.

[0124] Since the first condition further includes the third additional condition, when the last person 10 who has exited the first area A11 intends to exit the first area A11, the first control unit 123 causes the output unit 13 to output alert setting information, thereby preventing the alert setting operation from being forgotten with respect to the first area A11 and thereby improving security.

[0125] In addition, if the last exiting person 10 does not intend to exit the first area A11, the alert setting information is not output, which makes it possible to avoid the alert setting operation being performed erroneously in response to the output of the alert setting information.

[0126] (2-3-4a) Authentication and authentication operations The authentication operation is an operation for authentication. Authentication is at least to identify a person. Authentication in this embodiment is to identify a user who has entered and exited the first area A11.

[0127] The first control unit 123 identifies (authenticates) the user by, for example, acquiring a user ID from the mobile terminal 101 carried by the user. That is, the first control unit 123 determines that the user has been identified (that is, authentication has been established) when the user ID can be acquired from the mobile terminal 101 carried by the user. On the other hand, the first control unit 123 determines that the user has not been identified (that is, authentication has not been established) when the user ID cannot be acquired from the mobile terminal 101 carried by the user.

[0128] The authentication operation in this embodiment is an operation for a user to enter or exit the first area A11. In particular, the authentication operation by the last exiting person 10 is an operation for exiting from the first area A11.

[0129] The user ID included in the first entrance / exit information is acquired (received via NFC) from the mobile terminal 101 in response to an authentication operation. The time information constituting the first set of information included in the first entrance / exit information may also be acquired from the built-in clock of the processor in response to an authentication operation.

[0130] By determining that the last person to exit 10 has the intention to exit based on the authentication operation performed by the last person to exit 10, it is possible to accurately determine that the last person to exit 10 has the intention to exit (has the intention to exit), and ultimately to improve security.

[0131] (3) Details Next, the details of the entrance / exit control system 1 and the operation terminal 2 will be explained using Figures 1 to 4. Note that in the following, explanations of previously mentioned matters will be omitted or simplified.

[0132] (3-1) Overall structure 1, the access control system 1 is communicably connected to an operation terminal 2 via a communication medium 200. Furthermore, each of the access control system 1 and the operation terminal 2 can communicate via short-range wireless with a mobile terminal 101 carried by a user such as a last exiting person 10. The short-range wireless communication is, for example, communication via Bluetooth (registered trademark) or a wireless LAN (Local Area Network).

[0133] (3-2) Communication medium The communication medium 200 is, for example, a wired LAN, but may also be a wired communication medium other than a wired LAN, such as a serial communication cable.

[0134] (3-3) Operation terminal The operation terminal 2 is a terminal that is used in the access control system 1 and is operated by a person. The operation terminal 2 of this embodiment is provided outside the second boundary AL2, as shown in FIG.

[0135] As shown in FIG. 1, the operation terminal 2 includes an operation unit 21, a notification unit 22, and a communication unit 23.

[0136] (3-3-1) Operation section The operation unit 21 accepts operations. The operations accepted by the operation unit 21 are basically the various operations accepted by the acceptance unit 11 of the entry / exit control system 1, and in particular, the alert setting operation.

[0137] (3-3-2) Notification Department The notification unit 22 notifies the last exiting person 10 of the alert setting information when a first condition is satisfied regarding the last exiting person 10's exit from the first area A11.

[0138] Furthermore, when the alert setting is completed, the notification unit 22 further notifies completion information to the last exiting person 10. The completion information is information relating to the completion of the alert setting.

[0139] (3-3-3) Communications Department The communication unit 23 performs various types of communication. The various types of communication include, for example, wireless communication and wired communication. The wireless communication is, for example, short-range wireless communication with the mobile terminal 101. The wired communication is, for example, communication with the access control system 1 via a communication medium 200 such as a wired LAN.

[0140] (3-3-4) Collaboration with access control systems In the operation terminal 2, the communication unit 23 receives the alert setting information from the entry / exit control system 1, and the notification unit 22 outputs the received alert setting information as sound via the speaker of the operation terminal 2. In response to the sound output of the alert setting information, the operation unit 21 accepts the alert setting operation performed by the last exiting person 10, and the communication unit 23 transmits an operation signal indicating the accepted alert setting operation to the entry / exit control system 1 via the communication medium 200.

[0141] In the access control system 1, the communication unit 14 receives the operation signal, and the second control unit 124 performs security setting in response to the operation signal. When the security setting is completed, the communication unit 14 transmits completion information to the operation terminal 2.

[0142] In the operation terminal 2, the communication unit 23 receives the notification information from the entry / exit control system 1, and the notification unit 22 outputs the received notification information as sound via the speaker of the operation terminal 2.

[0143] (3-3-5) Advantages of operation terminals According to the operation terminal 2, when a first condition is met regarding the exit of the last person 10 from the first area A11, alert setting information is notified, thereby assisting people, particularly the last person 10, in manually setting alerts for the first area A11, and ultimately improving security.

[0144] When the alert setting is completed, the notification unit 22 further notifies the last exiting person 10 of the completion information.

[0145] According to this embodiment, by notifying the completion of the alert setting, the last exiting person 10 can be made aware of the completion of the alert setting.

[0146] (3-4) Details of the access control system The access control system 1 has a manual alert setting mode and an automatic alert setting mode. The access control system 1 can switch its operating mode between the manual alert setting mode and the automatic alert setting mode. For example, the reception unit 11 may receive a mode switching operation, and the processing unit 12 may switch the mode of the access control system 1 between the manual alert setting mode and the automatic alert setting mode.

[0147] (3-4-1) Manual alarm setting mode The manual alert setting mode is a mode in which alert setting is performed in response to an alert setting operation by a person.

[0148] The manual alert setting mode is an operating mode in which, when a first condition is met, the first control unit 123 causes the output unit 13 to output alert setting information for the first area A11, and the second control unit 124 executes alert setting in response to the alert setting operation performed by a person such as the last exiting person 10 upon receiving the output of the alert setting information.

[0149] The operation of the access control system 1 described in "(1) Overview" and "(2) Other Key Parts", particularly the operation of the second control unit 124 described in "(2-1) Second Control Unit", is the operation when the operation mode of the access control system 1 is the manual alert setting mode.

[0150] In other words, when the operating mode of the entry / exit management system 1 is the manual alert setting mode, the first control unit 123 performs a first condition judgment to determine whether or not the first condition is met based on one or more pieces of history information and number of people information managed by the management unit 121.

[0151] (3-4-2) Automatic alert setting mode The automatic alert setting mode is a mode in which alert settings are performed automatically.

[0152] The automatic alert setting mode is an operating mode in which, when the second condition is met, the first control unit 123 does not cause the output unit 13 to output alert setting information for the first area A11, and the second control unit 124 automatically executes the alert setting.

[0153] (3-4-2a) Second condition judgment When the operation mode of the access control system 1 is the automatic alert setting mode, the first control unit 123 performs a second condition determination. The second condition determination is to determine whether or not the second condition is met based on one or more pieces of history information and number of people information managed by the management unit 121.

[0154] (3-4-3) Second condition The second condition may be the same as or different from the first condition. In this embodiment, the second condition is the same as the first condition. However, the operation of the second control unit 124 when a negative determination result is obtained in the second condition determination based on the second condition (for example, when a No determination is made in each of steps S81 to S84: see FIG. 4) differs from the operation of the second control unit 124 when a negative determination result is obtained in the first condition determination based on the first condition (for example, when a No determination is made in each of steps S41 to S44: see FIG. 3).

[0155] The first condition includes the basic condition, and preferably further includes at least one additional condition from among the first to third additional conditions.

[0156] The first condition in this embodiment includes the basic condition and all of the first to third additional conditions.

[0157] (3-4-3a) Basic conditions The basic condition included in the second condition is the same as the basic condition included in the first condition, that is, "it is determined that the last exiting person 10 has exited the first area A11."

[0158] The basic condition included in the second condition is, for example, a determination of Yes in step S81 in the flowchart of Fig. 4. If the basic condition is not met (if a determination of No in step S81 is made), the alert setting is not executed (step S87).

[0159] By including the basic condition in the second condition, when it is determined that the last person 10 to leave the first area A11 has left, the alert setting can be automatically executed, thereby improving security.

[0160] (3-4-3b) First additional condition The first additional condition included in the second condition is the same as the first additional condition included in the first condition, that is, "it is determined that the last exiting person 10 has exited the second area A12."

[0161] The first additional condition included in the second condition is, for example, a determination of Yes in step S83 in the flowchart of Fig. 4. If the first additional condition is not satisfied (if a determination of No in step S83 is made), the alert setting is not executed (step S87).

[0162] Since the second condition further includes the first additional condition, when the last exiting person 10 who has exited from the first area A11 to the second area A12 leaves the second area A12, the second control unit 124 executes an alert setting, thereby enabling automatic and accurate execution of an alert setting for the first area A11, and ultimately improving security.

[0163] In addition, if the last person 10 to leave the first area A11 returns to the first area A11 without going outside the second area A12, the alert setting will not be executed, so it is possible to avoid accidentally executing the alert setting if the person temporarily leaves the room for a break, etc.

[0164] (3-4-3c) Second additional condition The second additional condition included in the second condition is, like the second additional condition included in the first condition, "the exit time of the last person 10 to exit from the first area A11 is determined to be within a specified time period."

[0165] The second additional condition included in the second condition is, for example, a determination of Yes in step S84 in the flowchart of Fig. 4. If the second additional condition is not satisfied (if a determination of No in step S84 is made), the alert setting is executed during a predetermined time period (step S86).

[0166] That is, when the second additional condition is satisfied, the alert setting is not executed, and when the current time reaches the start of the predetermined time period, the second control unit 124 executes the alert setting.

[0167] Since the second condition further includes a second additional condition, the second control unit 124 executes the alert setting when the exit time of the last person 10 to leave the first area A11 is during a specified time period, thereby improving security in the first area A11 during times when high security is required, such as at night or on holidays.

[0168] Furthermore, if the exit time of the last person 10 to leave the first area A11 is outside the specified time period, the alert setting will not be executed when the second additional condition is met, so it is possible to avoid the alert setting being erroneously executed with respect to the first area A11 during times when there are many people entering and exiting the first area A11, such as during the daytime on a weekday.

[0169] Thereafter, when the current time reaches the start of a predetermined time period, second control unit 124 executes the alert setting, thereby improving security during a time period when high security is required.

[0170] (3-4-3d)Third additional condition The third additional condition included in the second condition is, like the third additional condition included in the first condition, "it is determined that the last exiting person 10 has the intention to exit from the first area A11."

[0171] The third additional condition included in the second condition is, for example, a determination of Yes in step S82 in the flowchart of Fig. 4. If the third additional condition is not met (if a determination of No in step S82 is made), the alert setting is not executed (step S87).

[0172] By further including the third additional condition in the second condition, when the last exiting person 10 who has exited the first area A11 intends to exit the first area A11, the second control unit 124 executes the alert setting. With regard to the first area A11, the alert setting can be automatically executed at the appropriate timing, thereby improving security.

[0173] In addition, if the last exiting person 10 does not intend to exit the first area A11, the alert setting information is not output, which makes it possible to avoid the alert setting operation being performed erroneously in response to the output of the alert setting information.

[0174] (3-4-4) Detailed configuration 1, the access control system 1 includes a reception unit 11, a processing unit 12, an output unit 13, and a communication unit 14. The processing unit 12 includes a management unit 121, an acquisition unit 122, a first control unit 123, and a second control unit 124.

[0175] (3-4-4a) Reception The reception unit 11 receives various operations and various information. The various operations include, for example, an alert setting operation, an authentication operation, a mode switching operation, and a condition setting operation (all of which will be described later). The various information includes, for example, etc.

[0176] The reception unit 11 receives the signal, for example, via an NFC module or touch panel possessed by the access control system 1, but it may also receive the signal via an NFC module possessed by the access control system 1, or via the operation unit 21 of the operation terminal 2 (receiving the operation signal from the operation terminal 2 via the communication medium 200).

[0177] (3-4-4b) Processing section The processing unit 12 performs various types of processing, such as processing by a management unit 121, an acquisition unit 122, a first control unit 123, and a second control unit .

[0178] Furthermore, the processing unit 12 performs position measurement based on wireless signals transmitted and received via wireless communication between the communication unit 14 and the mobile terminal 101, and repeatedly executes positioning processing to acquire position information.

[0179] The location information is information about the location of a person such as the last exit person 10 or a mobile terminal 101 carried by the person. The location information can be acquired using the RSSI of the wireless signal received by the communication unit 14 from the mobile terminal 101, etc.

[0180] Furthermore, the processing unit 12 acquires information about a change in the position of the mobile terminal 101 based on a plurality of pieces of position information acquired at different times by repeatedly executing the positioning process.

[0181] The position change information is information relating to a change in the position of a person or mobile terminal 101. The position change information may include, for example, at least one of direction information indicating the direction in which the person or mobile terminal 101 is moving and speed information indicating the speed at which the person or mobile terminal 101 is moving.

[0182] Furthermore, the processing unit 12 also performs various determinations and the like which will be explained with reference to the flowcharts of FIGS.

[0183] (3-4-4c) Communications Department The communication unit 14 performs various types of communication. The various types of communication include, for example, wireless communication and wired communication. The wireless communication is, for example, short-range wireless communication with the mobile terminal 101. The wired communication is, for example, communication with the operating terminal 2 via a communication medium 200 such as a wired LAN.

[0184] (4) Hardware Next, the hardware included in each of the entrance / exit control system 1, the operation terminal 2, and the mobile terminal 101 will be described.

[0185] (4-1) Entrance / Exit Control System The access control system 1 includes, for example, a communication module, an NFC module, a display with a touch panel, a speaker, a processor, and a memory. The communication module realizes the function of a communication unit 14. The NFC module and the touch panel realize the function of a reception unit 11. The display and speaker realize the function of an output unit 13. The processor and memory realize the functions of a processing unit 12, a management unit 121, an acquisition unit 122, a first control unit 123, and a second control unit 124.

[0186] The memory stores various information such as first entry / exit information and first history information, as well as programs, and the processor works in cooperation with the communication module, NFC module, touch panel display, and speaker to operate based on the various information and programs stored in the memory, thereby realizing the functions of the entry / exit management system 1.

[0187] (4-2) Operation terminal The operation terminal 2 has a communication module, an NFC module, a display with a touch panel, a speaker, a processor, and a memory. The communication module realizes the function of a communication unit 23. The NFC module and the touch panel realize the function of an operation unit 21. The speaker and the display realize the function of a notification unit 22.

[0188] The memory stores various types of information and programs, and the processor works in cooperation with the communication module, NFC module, touch panel display, and speaker to operate based on the various types of information and programs stored in the memory, thereby realizing the functions of the operation terminal 2.

[0189] (4-3) Mobile devices The mobile terminal 101 has a short-range wireless communication module, a display with a touch panel, a speaker, a processor, and a memory. The short-range wireless communication module realizes short-range wireless communication between the access control system 1 (communication unit 14) and the operation terminal 2 (communication unit 23). The touch panel realizes the function of accepting various operations and various information. The speaker and display realize the function of notifying various information.

[0190] The memory stores various information and programs, including authentication information such as a user ID, and the processor works in cooperation with the short-range wireless communication module to operate based on the various information and programs stored in the memory, thereby realizing the functions of the mobile terminal 101.

[0191] (5) Example of operation of the access control system The access control system 1 operates, for example, in accordance with the flowcharts of Figures 2 to 4. The processing of Figures 2 to 4 (alert setting processing) is started in response to the startup of the access control system 1, and is ended in response to the shutdown of the access control system 1. In the access control system 1, processing of the management unit 121 (management processing) is executed in parallel with the processing of Figures 2 to 4.

[0192] The processing unit 12 determines whether or not a person has entered or exited the first area A11 (step S1). If it is determined that a person has not entered or exited the first area A11 (No in step S1), the processing returns to step S1.

[0193] If it is determined that a person has entered or exited the first area A11 (Yes), the acquisition unit 122 acquires the entry / exit information from the management unit 121 (step S2).

[0194] Next, the processing unit 12 determines whether the operation mode of the access control system 1 is the manual alert setting mode (step S3). If it is determined that the operation mode of the access control system 1 is not the manual alert setting mode (No in step S3: that is, the operation mode is the automatic alert setting mode), the processing proceeds to step S8.

[0195] If it is determined that the operation mode of the entry / exit control system 1 is the manual alert setting mode (Yes), the first control unit 123 executes a first condition determination process (step S4) that uses the entry / exit information acquired in step S2 to make a determination regarding the output of alert setting information based on a first condition. The first condition determination process will be described later.

[0196] Next, the first control section 123 causes the output section 13 to output alert setting information based on the determination result in the first condition determination process in step S4 (step S5).

[0197] Next, the processing unit 12 determines whether or not an alert setting operation has been performed (step S6). If it is determined that an alert setting operation has not been performed (No in step S6), the processing returns to step S1.

[0198] If it is determined in step S6 that the alert setting operation has been performed (Yes), the second control section 124 performs alert setting based on the alert setting operation (step S7), after which the process returns to step S1.

[0199] In step S8, the first control unit 123 executes a second condition determination process, which uses the entrance / exit information acquired in step S2 to determine whether to automatically execute the alert setting based on a second condition. The second condition determination process will be described later.

[0200] Next, the second control unit 124 automatically sets an alert based on the determination result in the second condition determination process of step S8 (step S9), after which the process returns to step S1.

[0201] (5-1) Example of the first judgment process The first condition determination process in step S4 is executed, for example, according to the flowchart of Fig. 3. Note that the first condition in this example includes the basic condition and the first to third additional conditions.

[0202] The first control unit 123 first makes a determination based on the basic conditions. That is, using the entry / exit information acquired in step S2, the first control unit 123 determines whether the person determined to have entered or exited the first area A11 in step S1 (hereinafter referred to as the "entering / exiting person") is the last person 10 to leave the first area A11 (step S41). If it is determined that the entering / exiting person is not the last person 10 to leave the first area A11 (No in step S41), the process proceeds to step S46.

[0203] If it is determined in step S41 that the person entering or leaving is the last person 10 to leave the first area A11 (Yes), the first control unit 123 further makes a determination based on a third additional condition. That is, the first control unit 123 determines whether the last person 10 has the intention to leave (step S42). In this example, whether there is an intention to leave is determined based on whether an authentication operation has been performed. If it is determined that the last person 10 does not have the intention to leave (No in step S42), the process proceeds to step S46.

[0204] If it is determined in step S42 that the last exiting person 10 has the intention to exit (Yes), the first control unit 123 further performs a determination based on the first additional condition. That is, the first control unit 123 determines whether the last exiting person 10 has exited from the second area A12 outside the first area A11 (step S43). If it is determined that the last exiting person 10 has not exited the second area A12 (No in step S43), the process proceeds to step S46.

[0205] If it is determined in step S43 that the last exiting person 10 has exited the second area A12 (Yes), the first control unit 123 further performs a determination based on a second additional condition. That is, the first control unit 123 determines whether the exit time of the last exiting person 10 from the first area A11 is within a predetermined time period (step S44). If it is determined that the exit time is not within the predetermined time period (No in step S44), the process proceeds to step S46.

[0206] If it is determined in step S44 that the exit time falls within the predetermined time period (Yes), the first control unit 123 acquires a determination result indicating execution of information output (step S45). After that, the process returns to the upper-level flowchart (see FIG. 2).

[0207] In step S46, the first control unit 123 acquires a determination result indicating that information output will not be executed, after which the process returns to the upper-level flowchart (see FIG. 2).

[0208] (5-2) Example of second judgment process The second condition determination process in step S8 is executed, for example, according to the flowchart of Fig. 4. Note that the second condition in this example includes the basic condition and the first to third additional conditions.

[0209] The first control unit 123 first makes a determination based on the basic conditions. That is, using the entry / exit information acquired in step S2, the first control unit 123 determines whether the person who entered and left the first area A11 and who was determined to have entered and left the first area A11 (Yes) in step S1 is the last person 10 to leave the first area A11 (step S81). If it is determined that the person who entered and left the first area A11 is not the last person 10 to leave the first area A11 (No in step S81), the process proceeds to step S87.

[0210] If it is determined in step S81 that the person entering or leaving is the last person 10 to leave the first area A11 (Yes), the first control unit 123 further makes a determination based on a third additional condition. That is, the first control unit 123 determines whether the last person 10 has the intention to leave (step S82). In this example, whether there is the intention to leave is determined based on whether an authentication operation has been performed. If it is determined that the last person 10 does not have the intention to leave (No in step S82), the process proceeds to step S87.

[0211] If it is determined in step S82 that the last exiting person 10 has the intention to exit (Yes), the first control unit 123 further performs a determination based on the first additional condition. That is, the first control unit 123 determines whether the last exiting person 10 has exited from the second area A12 outside the first area A11 (step S83). If it is determined that the last exiting person 10 has not exited the second area A12 (No in step S83), the process proceeds to step S87.

[0212] If it is determined in step S83 that the last exiting person 10 has exited the second area A12 (Yes), the first control unit 123 further performs a determination based on a second additional condition. That is, the first control unit 123 determines whether the exit time of the last exiting person 10 from the first area A11 is within a predetermined time period (step S84). If it is determined that the exit time is not within the predetermined time period (No in step S84), the process proceeds to step S86.

[0213] If it is determined in step S84 that the exit time falls within the predetermined time period (Yes), the first control unit 123 acquires a determination result indicating that the alert setting is to be executed (step S85). After that, the process returns to the upper-level flowchart (see FIG. 2).

[0214] In step S86, the first control unit 123 acquires a determination result indicating that the alert setting is to be executed in the predetermined time period, after which the process returns to the upper-level flowchart (see FIG. 2).

[0215] In step S87, the first control section 123 acquires a determination result indicating that the alert setting is not executed, and then the process returns to the upper-level flowchart (see FIG. 2).

[0216] (6)Entry / exit management method The entrance / exit management method of the present disclosure is an entrance / exit management method for managing entrance / exit to a first area A11 within a predetermined area A1. The entrance / exit management method includes an acquisition step, an output step, and a first control step.

[0217] In the acquisition step, entry / exit information is acquired. The entry / exit information is information regarding people entering and exiting the first area A11. In the first control step, based on the entry / exit information acquired in the acquisition step, if a first condition is met regarding the exit of the last exiting person 10 from the first area A11, alert setting information is output in the output step. The alert setting information is information for setting alert for the first area A11.

[0218] The entry / exit management method may include, for example, step S2 (acquisition step), step S5 (output step), and step S45 (first control step) among steps S1 to S9 described in the flowchart of FIG. 2, steps S41 to S46 described in the flowchart of FIG. 3, and steps S81 to S87 described in the flowchart of FIG. 4.

[0219] (7) Program The program of the present disclosure is a program for causing one or more processors to execute the above-described access control method. The one or more processors are, for example, any one, two, or three of the processor of the access control system 1, the processor of the operation terminal 2, and the processor of the mobile terminal 101. The program may be a program for causing a computer system to function as the access control system 1.

[0220] (8) Computer Systems The access control system 1 of the present disclosure includes a computer system. The computer system is primarily composed of a processor and memory as hardware. The functions of the access control system 1 of the present disclosure are realized by the processor executing a program stored in the memory of the computer system. The program may be pre-stored in the memory of the computer system, provided via a telecommunications line, or provided on a non-transitory recording medium readable by the computer system, such as a memory card, optical disk, or hard disk drive. The processor of the computer system is composed of one or more electronic circuits, including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). The integrated circuits, such as ICs and LSIs, are referred to by different names depending on the degree of integration, and include integrated circuits called system LSIs, very large-scale integrations (VLSIs), and ultra-large-scale integrations (ULSIs). Furthermore, field-programmable gate arrays (FPGAs), which are programmed after the LSI is manufactured, or logic devices that allow the reconfiguration of internal connections or circuit partitions within the LSI, can also be used as processors. The electronic circuits may be integrated into one chip or distributed across multiple chips. The chips may be integrated into one device or distributed across multiple devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

[0221] Furthermore, it is not essential for the access control system 1 that multiple functions are concentrated in one housing, and the components of the access control system 1 may be distributed across multiple housings. Furthermore, at least some of the functions of the access control system 1 may be realized by the cloud (cloud computing) or the like.

[0222] (9) Variations (9-1) First Modification of the Access Control System The access control system 1 may further have the functions of the operation terminal 2. In addition to the configuration of the access control system 1 of the embodiment (see FIG. 1 ), the access control system 1 of this modified example further comprises an operation unit 21 and a notification unit 22. In this modified example, the operation terminal 2 is not necessary, and the communication unit 23 provided in the operation terminal 2 of the embodiment may also serve as the communication unit 14 of the access control system 1.

[0223] (9-2) Second Modification of the Access Control System The access control system 1 may have a manual security setting mode and not have an automatic security setting mode. The access control system 1 of this modification does not have a mode switching function and performs the same operations as in the manual security setting mode described in the embodiment.

[0224] (9-3) Modified layout of the access control system In the embodiment, the entrance / exit control system 1 is provided in the second area A12 (see FIG. 1), but it may be provided in the first area A11 or outside the predetermined area A1.

[0225] When the access control system 1 is installed outside the predetermined area A1, a communication device including a communication unit 14 is preferably installed near the first boundary AL1. The communication device performs short-range wireless communication with a mobile terminal 101 present inside the predetermined area A1, and also communicates with the access control system 1 via a communication medium 200.

[0226] (9-4) Modified example of operation terminal The operation terminal 2 may further have the functions of the access control system 1. In addition to the configuration of the operation terminal 2 of the embodiment (see FIG. 1 ), the operation terminal 2 of this modified example further includes a processing unit 12, a management unit 121, an acquisition unit 122, a first control unit 123, and a second control unit 124. In this modified example, the reception unit 11, the output unit 13, and the communication unit 14 included in the access control system 1 of the embodiment may also be used as the operation unit 21, the notification unit 22, and the communication unit 23 included in the operation terminal 2, respectively.

[0227] (9-5) Modified example of the layout of the operation terminal In the embodiment, the operation terminal 2 is provided outside the second boundary AL2 (see FIG. 1), but may be provided, for example, inside the second boundary AL2 or outside the first boundary A12. In other words, the operation terminal 2 may be provided in the second area A12.

[0228] (9-6) Modification of the order of the basic judgment and the first to third additional judgments in the first judgment process In the first judgment process of the embodiment (see FIG. 3), the basic judgment (step S41), the third additional judgment (step S42), the first additional judgment (step S43), and the second additional judgment (step S44) are executed in this order, but the basic judgment (step S41) needs to be executed first, and the order of the first to third additional judgments (steps S42 to S44) following the basic judgment may be changed as appropriate.

[0229] (9-7) Modification of the order of the basic judgment and the first to third additional judgments in the second judgment process In the second judgment process of the embodiment (see FIG. 4), the basic judgment (step S81), the third additional judgment (step S82), the first additional judgment (step S83), and the second additional judgment (step S84) are executed in this order, but the basic judgment (step S81) only needs to be executed first, and the order of the first to third additional judgments (steps S82 to S84) following the basic judgment may be changed as appropriate.

[0230] (9-8) Modified example of the method for acquiring the first number of people information In an embodiment, the current first number of people information is obtained by updating the first number of people information stored in memory using the first entry / exit information generated by the management unit 121, but it may also be obtained by calculation using one or more first history information stored in memory.

[0231] In this modification, the management unit 121 acquires, for example, the number of pieces of history information in which the entry / exit flag of the last group information is "entered" among one or more pieces of first history information as the current number-of-people information.

[0232] (9-9) Modified example of detection method for entering and leaving a predetermined area In the embodiment, entry and exit to the specified area A1 is detected based on short-range wireless communication between the mobile terminal 101 and each of the entry and exit management system 1 and the operation terminal 2, but in this modified example, it may also be detected based on short-range wireless communication between the mobile terminal 101 and either the entry and exit management system 1 or the operation terminal 2.

[0233] (9-10) Modified example of the method for detecting entry and exit to the first area In the embodiment, entry and exit to the first area A11 is detected based on short-range wireless communication between the mobile terminal 101 and the entry and exit management system 1, but in this modified example, it may also be detected based on short-range wireless communication between the mobile terminal 101 and each of the entry and exit management system 1 and the operating terminal 2.

[0234] Alternatively, if the short-range wireless communication range of an operating terminal 2 (see Figure 1) located outside the second boundary AL2 extends to the second area A12 and even the first area A11, entry and exit to the specified area A1 may be detected based on short-range wireless communication between the mobile terminal 101 and the operating terminal 2.

[0235] (9-11) Variation of headcount management: Second headcount management In this modified example, the management unit 121 performs second number-of-people management in addition to the first number-of-people management. The second number-of-people management is management of the number of people related to the second area A12. The second number-of-people management is, for example, calculating the number of people present in the second area A12 and acquiring second number-of-people information indicating the calculation result. For example, the management unit 121 subtracts the number of people indicated by the first number-of-people information (i.e., the number of people present in the first area A11) from the number of people indicated by the number-of-people information (i.e., the number of people present in the predetermined area A1) and acquires second number-of-people information indicating the subtraction result.

[0236] (9-12) Modified authentication In addition to identifying the user, the authentication may also include confirming that the identified user is a user authorized to access the first area A11 (for example, determining whether the user is an employee). In this case, in addition to one or more user IDs corresponding to one or more users, the memory of the access control system 1 further stores one or more employee IDs corresponding to one or more employees among the one or more users.

[0237] (9-13) Modified example of authentication operation The authentication operation may be performed by a user, such as the last exiting person 10, holding an IC card storing a user ID over a reader or touching the IC card to the reader. The user ID is read from the IC card by the reader. The reader is either the access control system 1 or the operation terminal 2, whichever has an NFC module. In the embodiment, each of the access control system 1 and the operation terminal 2 is a reader.

[0238] (9-14) Modifications of NFC modules and readers In the embodiment, the access control system 1 and the operation terminal 2 each have an NFC module, but it is also possible for only one of the access control system 1 and the operation terminal 2 to have an NFC module. In this modification, the access control system 1 is a reader having an NFC module. When the last person 10 to exit the first area A11 intends to exit, he or she performs an authentication operation by holding a mobile terminal 101 or an IC card over the NFC module of the access control system 1 (reader).

[0239] (9-15) First variant of the entry / exit flag In the embodiment, the entry / exit flag is "enter" or "1" indicating entry into the first area A11, or "exit" or "0" indicating exit from the first area A11. However, the entry / exit flag may be a flag in which two values ​​are arranged corresponding to the source area and the destination area. The flag in which two values ​​are arranged may be, for example, "02" indicating entry into the second area A12 from outside the predetermined area A1, "21" indicating entry from the second area A12 to the first area A11, "12" indicating exit from the first area A11 to the second area A12, and "20" indicating exit from the second area A12 to outside the predetermined area A1. Alternatively, the entry / exit flag may be "2" indicating exit from the first area A11 (movement from the first area A11 to the second area A12).

[0240] (9-16) Second variant of the entry / exit flag In the embodiment, when entry or exit into the first area A11 is detected, whether the detected entry or exit is an entry or exit is determined based on the position and position change of the mobile terminal 101, and an entry / exit flag indicating the determination result is obtained, but in this modified example, the entry / exit flag may be obtained from the reader in response to an authentication operation.

[0241] The reader in this modified example can select one of a plurality of modes including, for example, "clock in" and "clock out." When the reader's mode is "clock in," an entry / exit flag indicating "1" may be acquired in response to the authentication operation, and when the reader's mode is "clock out," an entry / exit flag indicating "0" may be acquired in response to the authentication operation.

[0242] (9-17) Modification of detection of entry and exit to the first area In the embodiment, entry and exit to the first area A11 is detected based on position information and position change information, but in this modification, it is detected in response to the reception of an authentication operation.

[0243] Alternatively, in this modification, entry and exit to the first area A11 may be detected based on a signal from a sensor (for example, an infrared sensor, a camera, or the like) provided near the first boundary AL1.

[0244] (9-18) Modification of alarm setting operation In the embodiment, the alert setting operation is the operation of pressing the "Execute" button, which indicates that the alert setting is to be executed, but in this modified example, it is the operation of pressing the "Cancel" button, which indicates that the alert setting is not to be executed (that the alert setting will not be executed).

[0245] In this modified example, if the "Cancel" button is pressed within a certain time after the alert setting information is output, the second control unit 124 does not execute the alert setting. If the "Cancel" button is not pressed even after a certain time has passed since the alert setting information was output, the second control unit 124 executes the alert setting.

[0246] According to this modified example, if the last person to exit 10 confirms that the alert setting has not been performed through an alert setting operation, the second control unit 124 will not perform the alert setting, thereby enabling the last person to exit 10 to avoid manually performing the alert setting.

[0247] (9-19) Variations of the judgment regarding the first and second conditions In the embodiment, the first control unit 123 makes a determination regarding each of the first conditions, but in a modified example, the determination may be made by an element other than the first control unit 123 (for example, a first condition determination unit provided in the processing unit 12: not shown). Similarly, in the embodiment, the first control unit 123 makes a determination regarding each of the second conditions, but in a modified example, the determination may be made by an element other than the first control unit 123 (for example, a second condition determination unit provided in the processing unit 12: not shown).

[0248] (9-20) Modification of the first and second conditions: Setting conditions for each of a plurality of first regions A plurality of first areas A11 may exist within the predetermined area A1. In this modification, a plurality of rooms, each of which is a first area A11, exist indoors as the first area A11, and furthermore, a passageway, which is a second area A12, exists between the plurality of rooms.

[0249] When there are multiple first areas A11, a different first condition can be set for each first area A11 in the access control system 1. More specifically, for each of the multiple first areas A11, the reception unit 11 receives a condition setting operation for setting a first condition, and the processing unit 12 sets the first condition in accordance with the received condition setting operation.

[0250] Furthermore, a different second condition can be set for each first area A11 in the access control system 1. Specifically, for each of the multiple first areas A11, the reception unit 11 receives a condition setting operation for setting the second condition, and the processing unit 12 sets the second condition in accordance with the received condition setting operation.

[0251] According to this modification, by setting a different first condition for each first area A11, it is possible to manually achieve the security required for each of the multiple first areas A11.

[0252] Furthermore, by setting a different second condition for each first area A11, it is possible to automatically achieve the security required for each of the plurality of first areas A11.

[0253] (9-21) Modification of processing according to the result of determination regarding the second additional condition In the embodiment, if the determination result regarding the second additional condition is negative (determined No in step S84), the alert setting is executed in a predetermined time period (step S86), but in this modified example, the alert setting does not have to be executed. That is, in this modified example, step S46 in the flowchart of FIG. 4 is omitted, and if the determination in step S84 is No, the process may proceed to step S87.

[0254] (10) Summary The access control system (1) according to the first aspect is an access control system (1) that manages access to and exit from a first area (A12) within a predetermined area (A1). The access control system (1) includes an acquisition unit (122), an output unit (13), and a first control unit (123). The acquisition unit (122) acquires first access and exit information. The first access and exit information is information relating to people entering and exiting the first area (A12). The first control unit (123) causes the output unit (13) to output alert setting information when a first condition is satisfied regarding the exit of the last exiting person (10) from the first area (A12) based on the first access and exit information acquired by the acquisition unit (122). The alert setting information is information for setting alert for the first area (A12).

[0255] According to this aspect, when the first condition is satisfied regarding the exit of the last exiting person (10) from the first area (A12), alert setting information is output, thereby assisting in manually setting alert settings for the first area (A12) and thereby improving security.

[0256] The entry / exit control system (1) according to the second aspect is the same as that according to the first aspect, but further includes a second control unit (124). The second control unit (124) executes an alert setting. The alert setting information includes notification information. The notification information is information that guides the last-exiting person (10) to perform an alert setting operation to cause the second control unit (124) to execute the alert setting.

[0257] According to this aspect, since the alert setting information includes the notification information, it is possible to guide the last person 10 to leave the first area A12 so as to perform an alert setting operation for the first area A12. The last person 10 to leave the first area A12 performs an alert setting operation in response to the guidance, thereby enabling the accurate manual execution of alert setting and thus further improving security.

[0258] In the entry / exit control system (1) according to the third aspect, in the second aspect, the alert setting operation is an operation indicating whether or not the alert setting is being executed. The notification information includes confirmation information. The confirmation information is information for confirming with the last exiting person (10) whether or not the alert setting is being executed.

[0259] According to this aspect, the notification information includes confirmation information, which allows the last exiting person (10) to confirm whether or not an alert setting has been implemented for the first area (A12). For example, if the last exiting person (10) confirms that an alert setting has been implemented for the first area (A12), the alert setting can be implemented, thereby enabling the appropriate manual implementation of an alert setting and further improving security. Furthermore, if the last exiting person (10) confirms that an alert setting has not been implemented for the first area (A12), the alert setting can be not implemented, thereby avoiding unnecessary implementation of an alert setting.

[0260] In the entry / exit control system (1) according to the fourth aspect, in the third aspect, the second control unit (124) executes the alert setting when it is confirmed that the alert setting operation has been performed by the last exiting person (10).

[0261] According to this embodiment, after the last person to leave (10) confirms that the security setting has been implemented by performing the security setting operation, the security setting is implemented, thereby enabling the security setting to be implemented accurately and manually, thereby further improving security.

[0262] In the entry / exit control system (1) according to the fifth aspect, in any of the first to fourth aspects, the first condition includes that it is determined that the last exiting person (10) has exited the first area (A12).

[0263] According to this aspect, the first condition includes the exit of the last person to leave (10) from the first area (A12), and thus alert setting information is output when the last person to leave (10) leaves the first area (A12). Based on the output alert setting information, alert setting for the first area (A12) is manually performed, thereby improving security.

[0264] In the access control system (1) according to the sixth aspect, in the fifth aspect, the first condition further includes that it is determined that the last exiting person (10) has exited from the second area (A12). The second area (A12) is an area outside the first area (A12) within the predetermined area (A1).

[0265] According to this aspect, when the last person (10) to leave the first area (A12) to the second area (A12) leaves the second area (A12), alert setting information is output, thereby enabling the execution of manual and accurate alert setting for the first area (A12) and thereby improving security. Note that if the last person (10) to leave the first area (A12) returns to the first area (A12) without leaving the second area (A12), alert setting information is not output, so that it is possible to avoid accidentally setting the alert when temporarily leaving the room for a break, etc.

[0266] In the entry / exit management system (1) according to the seventh aspect, in the fifth or sixth aspect, the first condition further includes that the exit time of the last person (10) to exit from the first area (A12) is determined to be within a predetermined time period.

[0267] According to this aspect, by outputting the alert setting information when the exit time of the last person (10) to leave the first area (A12) falls within a predetermined time period, it is possible to improve security for the first area (A12) during times when high security is required, such as at night or on holidays. Note that if the exit time falls outside the predetermined time period, the alert setting information is not output. This makes it possible to avoid erroneous alert setting operations being performed in response to the output of the alert setting information during times when there are many people entering and exiting the first area (A12) and alert setting is not necessary, such as during the daytime on a weekday.

[0268] In the entry / exit control system (1) according to the eighth aspect, in any of the fifth to seventh aspects, the first condition further includes that the last exiting person (10) is determined to have the intention to exit the first area (A12).

[0269] According to this aspect, by outputting the alert setting information when the last exiting person (10) intends to exit the first area (A12), it is possible to prevent the last exiting person (10) from forgetting to perform the alert setting operation for the first area (A12), thereby improving security. Note that if the last exiting person (10) does not intend to exit the first area (A12), the alert setting information is not output, which makes it possible to prevent the alert setting operation from being performed erroneously in response to the output of the alert setting information.

[0270] In the entry / exit control system (1) according to the ninth aspect, in the eighth aspect, the determination that the last exiting person (10) intends to exit is based on an authentication operation performed by the last exiting person (10). The confirmation operation is an operation for exiting from the first area (A12).

[0271] According to this embodiment, it is possible to accurately determine whether the last exiting person (10) has the intention to exit (has the intention to exit), thereby improving security.

[0272] In the entry / exit control system (1) according to the tenth aspect, in any one of the first to ninth aspects, when there are a plurality of first areas (A12), different first conditions can be set for each of the first areas (A12).

[0273] According to this aspect, by setting a different first condition for each first area, it is possible to achieve the security required for each of the plurality of first areas.

[0274] The access control system (1) according to an eleventh aspect is the system of any one of the first to tenth aspects, further comprising a second control unit (124). The second control unit (124) executes an alert setting. The access control system (1) has an automatic alert setting mode. The automatic alert setting mode is an operation mode in which, when a second condition is satisfied, the first control unit (123) does not cause the output unit (13) to output alert setting information for the first area (A12), and the second control unit (124) automatically executes the alert setting. The second condition includes a determination that the last exiting person (10) has exited the first area (A12).

[0275] According to this embodiment, in an operating mode (automatic alert setting mode) in which alert setting is automatically performed without outputting alert setting information, alert setting can be automatically performed when it is determined that the last person (10) has exited the first area (A12).

[0276] An operation terminal (2) according to a twelfth aspect is used in an access control system (1) that manages access to and exit from a first area (A12) within a predetermined area (A1). The operation terminal (2) is provided outside a boundary (AL2) between the predetermined area (A1) and the outside of the predetermined area (A1), or in a second area (A12). The second area (A12) is an area within the predetermined area (A1) that is outside the first area (A12). The operation terminal (2) includes an operation unit (21) and a notification unit (22). The operation unit (21) accepts operations. The notification unit (22) notifies the last exiting person (10) of alert setting information when a condition is satisfied regarding the last exiting person (10)'s exit from the first area (A12). The alert setting information is information for setting alert for the first area (A12).

[0277] According to this aspect, when the conditions are met regarding the exit of the last person (10) from the first area (A12), alert setting information is notified, thereby assisting in manually setting alert settings for the first area (A12) and thereby improving security.

[0278] In the operation terminal (2) according to the thirteenth aspect, in the twelfth aspect, the alert setting information includes notification information. The notification information is information that guides the last exiting person (10) to perform an alert setting operation. The alert setting operation is an operation that causes the entry / exit control system (1) to execute an alert setting.

[0279] According to this aspect, since the alert setting information includes the notification information, it is possible to guide the last person (10) to leave the first area (A12) so as to perform an alert setting operation for the first area (A12). When the last person (10) performs an alert setting operation in response to the guidance, the entry / exit control system (1) can manually and accurately set alerts, thereby further improving security.

The confirmation information is information for confirming with the last exiting person (10) whether or not the alert setting is enabled.

[0281] According to this aspect, the notification information includes confirmation information, so that it is possible to confirm with the last exiting person (10) whether or not an alert setting has been implemented for the first area (A12). For example, if the last exiting person (10) confirms that an alert setting has been implemented for the first area (A12), the access control system (1) can implement the alert setting, thereby enabling the appropriate manual implementation of the alert setting and ultimately further improving security. Furthermore, if the last exiting person (10) confirms that an alert setting has not been implemented for the first area (A12), the access control system (1) can avoid implementing an unnecessary alert setting by not implementing the alert setting.

[0282] In the operation terminal (2) according to a fifteenth aspect, in the thirteenth or fourteenth aspect, the notification unit (22) further notifies the last exiting person (10) of completion information when the alert setting is completed. The completion information is information regarding the completion of the alert setting.

[0283] According to this embodiment, by notifying the last exiting person (10) of the completion of the alert setting, the last exiting person (10) can be made aware of the completion of the alert setting.

[0284] An entrance / exit management method according to a sixteenth aspect is an entrance / exit management method for managing entrance / exit to an area (A12) within a predetermined area (A1). The entrance / exit management method includes an acquisition step (S2), an output step (S5), and a control step (S45). In the acquisition step (S2), first entrance / exit information is acquired. The first entrance / exit information is information relating to people entering and exiting the area (A12). In the control step (S45), based on the first entrance / exit information acquired in the acquisition step (S2), if a condition is satisfied regarding the exit of the last exiting person (10) from the area (A12), alert setting information is output in the output step (S5). The alert setting information is information for setting alert for the area (A12).

[0285] According to this embodiment, when the conditions are met regarding the exit of the last person (10) from the area (A12), alert setting information is output, thereby assisting in manually setting alert settings for the area (A12) and thereby improving security.

[0286] A program according to a seventeenth aspect is a program for causing one or more processors to execute the entrance / exit management method of the sixteenth aspect.

[0287] According to this aspect, when the first condition is satisfied regarding the exit of the last exiting person (10) from the first area (A12), alert setting information is output, thereby assisting in manually setting alert settings for the first area (A12) and thereby improving security.
