Description

  The present invention relates to an entry / exit management system for managing entry / exit of a user into / from a building, entry / exit in a building, and the like, and in particular, an entry / exit management system capable of confirming whether or not users have user qualifications. About.

  Conventionally, an entrance / exit management system is configured by an authentication device that is installed near an entrance and that authenticates user qualifications and an access control device that controls locking and unlocking of a door according to the authentication result of the authentication device. The entrance and exit of the room was managed. (Patent Document 1)

  In recent years, the ID card carried by each user has a function that can display the presence or absence of user qualifications in the room where the user is located. An entrance / exit management system with a people monitoring function that confirms the qualification of the person in charge has been proposed. (Patent Document 2)

JP 06-004536 A JP2009-99052A

  By the way, depending on the company that has already introduced the entrance / exit management system that does not have the people monitoring function as in Patent Document 1, the existing entrance / exit management system is renovated and the people monitoring function is applied to all places / users. Instead, there was a need to apply the crowd monitoring function only to a specific place / user. The above needs provide an ID card holder or an admission badge that is used in combination with an ID card on a daily basis to provide a display function that allows neighboring users to mutually confirm user qualifications, and this requires a crowd monitoring function. It can be satisfied by using it in places.

  However, in such an entry / exit management system, a person who does not possess an ID card holder or the like is suspected by surrounding users as being an unauthorized user, and therefore illegally obtains an ID card holder or the like of another user. There is a risk of trying to enter the room in combination with their own (or illegally obtained) ID card. In addition, the ID card holder, which is assumed to be loaned from the administrator only when necessary, is loaned to anyone from the outside, unlike the ID card that is loaned for each user with a personal name specified. Whether it is an ID card holder or the like cannot be identified. Therefore, when an administrator mistakenly lends an ID card holder or the like associated with another user to another user, or when a user misuses an ID card holder or the like lent to another user Is also assumed in operation.

  Therefore, the present invention is a user who changes the display of an ID card holder or the like in which the combination of the ID card and the ID card holder or the like is incorrect, and the user uses an ID card holder or the like having a different correspondence. Is intended to be detected by the person or the surrounding users.

  In order to solve such a problem, there are a user management device, a display device that is attached to the user and changes display according to a control signal from the user management device, and the display device exists in a predetermined area near the entrance / exit. A location detecting device that detects that the user management device is informed, and is an entrance / exit management system with a people monitoring function that allows a user to mutually confirm the display on the display device, the user management The apparatus includes a storage unit storing correspondence information indicating a correspondence relationship between the user and the display device, and a user identification unit that identifies the user by an identification code uniquely assigned to each user. If the display device having the corresponding relationship with the user is not detected in the same predetermined area as the user identified by the user identification means, the display device existing in the predetermined area is not detected. An entry / exit management system comprising: a determination unit that determines a corresponding warning state; and a display control unit that displays the corresponding warning state by non-contact communication on the display device that is determined to be a corresponding warning state by the determination unit. provide.

  With the above configuration, when a user who has an ID card holder or the like that is different from the correspondence registered in advance is detected, the ID card holder or the like of the user can be displayed as a warning.

In the access control system, the determination unit determines that all the display devices existing in the predetermined area are in a corresponding warning state.
When the determination means detects a user who possesses an ID card holder or the like that is different from the pre-registered correspondence, the ID card holders of all users in a predetermined area where the ID card holder or the like exists Etc. can be displayed as warnings. This makes it easy for all users who are close to unauthorized users who have different correspondences with ID card holders, etc. to recognize that the unauthorized users are nearby. It is possible to call attention to the person entering the room.

Furthermore, in the access control system, the determination unit is configured such that the user identified by the user identification unit and the display device corresponding to the user are the same after the display device enters a corresponding warning state. When it is determined that the display device is present in the predetermined area, the display control unit has a function of canceling the corresponding warning state of the display device. When the determination unit cancels the corresponding warning state, the display control unit displays the corresponding warning state of the display device. Has a function to cancel.
A user who wears an ID card holder or the like that has displayed a warning by the determination means and the display control means indicates that the correspondence between the ID card and the ID card holder or the like by the ID card operation is the correspondence information registered in advance. When the match is confirmed, the warning display can be canceled. As a result, a user who has an appropriate correspondence with the ID card holder or the like can perform the release operation himself / herself without relying on the release operation by the administrator or the like, thereby reducing the management load when operating the access control system. be able to. On the other hand, even if an unauthorized user whose correspondence relationship with the ID card holder or the like is not appropriate, even if the card operation is performed, the unauthorized user cannot perform the release operation himself, and the release operation by the administrator or the like is required. Therefore, the users around the unauthorized user can finally notice who is the unauthorized user by monitoring the public, and the unauthorized user continues to illegally use the ID card holder. I can't.

  In a preferred aspect of the present invention, the user identification means is the access control system comprising an ID card possessed by the user and storing the identification code, and a card reader that reads the identification code. .

  As described above, the entrance / exit management system of the present invention can generate an ID that can be generated by separating a display unit from an ID card to an ID card holder or the like that can confirm whether or not users have user qualifications. Abnormality in the correspondence between the card and the ID card holder can be detected by monitoring the people.

  Hereinafter, as an embodiment of the present invention, an example in which the access control system according to the present invention is applied to a building having a plurality of rooms will be described with reference to the drawings.

  FIG. 1 is a diagram schematically illustrating the configuration and operation image of the access control system according to the present embodiment. In FIG. 1, a building is divided into a common passage shared by users of each room, a room A limited to a specific user, and a room B. Doors D1 and D2 with electric locks are provided between the room A and the room B and the common passage, respectively, and entry into the room A or the room B from the common passage is restricted. The doors D1 and D2 with electric locks are electric locks only when it is possible to authenticate with a user having room entry qualification based on a signal read from the ID card 3 carried by the user with the card readers CR1 and CR2. Is controlled by the access control devices M1 and M2. In addition, the doors D1 and D2 with electric locks are normally maintained in a locked state.

  The ID card 3 is housed in an ID card holder 30 having a display unit 34 that can display three types of display: no display, room entry permission state, room entry not permitted state, and corresponding warning state. The ID card holder 30 can display a plurality of states at the same time.

  The management device 1 is installed in a security room or a management room, for example, and is connected to the access control devices M1 and M2 and the transmission / reception devices R1 and R2 via the communication network 2, and wirelessly communicates via the transmission / reception devices R1 and R2. Thus, display control of the display unit 34 is performed on the ID card holder 30. Note that the transmission / reception devices R1 and R2 use only the areas C1 and C2 in the vicinity of the entrance / exit as the areas capable of wireless communication with the ID card holder 30.

  Next, an outline operation of the access control system will be described. In FIG. 1, a user X is a person who has a room entry qualification and has an ID card 3 and an ID card holder 30 corresponding to the user X. User Y has a qualification to enter room A but does not have a qualification to enter room B, and has ID card 3 and ID card holder 30 corresponding to user Y. . The user Z is a person who has entry qualifications for the room A and has the ID card 3 corresponding to the user Z but does not have the ID card holder 30 corresponding to the user Z. Here, it is assumed that the user Z is a person who has the ID card holder 30 corresponding to the user A. The user W is qualified to enter the room A and has the ID card 3 and the ID card holder 30 corresponding to the user W.

  A case where the user X enters the room A from the shared passage will be described. As a premise, the display unit 34 of the ID card holder 30 is basically in a non-display state because there is no particular restriction on the users located in the shared passage. For this reason, the display part 34 of the ID card holder 30 possessed by the user X before entering the room A is not displayed.

  First, the ID card holder 30 carried by the user X transmits its own holder ID assigned to each ID card holder 30 to the transmitter / receiver R1 when entering the inside of the monitoring area C1. The transmission / reception device R1 that has received the holder ID transmits the holder ID to the management device 1 via the communication network 2. The management apparatus 1 that has received the holder ID detects that the ID card holder 30 of the user X has entered the monitoring area C1.

  In order to unlock door D1 with an electric lock, user X holds ID card 3 he holds over card reader CR1 provided on the external wall surface in the common passage, and authenticates the entrance qualification of ID card 3 Request. The card reader CR1 requested to authenticate from the ID card 3 transmits the identification code read from the ID card 3 possessed by the user X to the connected access control device M1. The entrance / exit control device M1 collates whether or not the received identification code is an identification code that is permitted to enter the room in advance. In other words, an identification code that has been stored in advance and that has been permitted to enter the room is compared with an identification code received from the card reader CR1, and if they match, it is authenticated that there is a room entry qualification. Here, since the user X is qualified to enter the room A, the user X transmits an unlock signal to the connected door D1 with an electric lock. The entrance / exit control device M1 controls the unlocking of the door D1 with an electric lock, and transmits an authentication result indicating that it is a room permitter from the communication network 2 to the management device 1.

  The door D1 with an electric lock unlocks the electric lock for a predetermined time when an unlock signal is received from the access control device M1.

  On the other hand, when the management apparatus 1 receives the authentication result from the access control apparatus M1, the management apparatus 1 checks whether or not the ID card holder 30 of the user X exists in the monitoring area C1. As described above, the management device 1 that has detected the presence of the ID card holder 30 of the user X in the monitoring area C1 displays the permission to enter the ID card holder 30 corresponding to the identification code of the ID card 3. The command is transmitted via the transmission / reception device R1, and the entry permission state is displayed on the display unit 34 of the ID card holder 30 for a predetermined time. The correspondence relationship between the identification code of the ID card 3 and the holder ID of the ID card holder 30 is stored in advance in the management device 1 as will be described later.

  In this way, when the user X enters the room A, the user X is authenticated as a room permitter and the electric lock is unlocked for a certain period of time. At this time, the ID card holder 30 of the user X is lit with a lamp indicating a room entry permission state. As a result, the user X can clearly indicate to the surrounding users that he / she is permitted to enter the room A, and the user X himself / herself has the authority to enter the room A. can do.

  Next, an operation when the user Y who does not have the qualification to enter the room B tries to enter the room B will be described.

  First, the ID card holder 30 carried by the user Y transmits the holder ID assigned to each ID card holder 30 to the transmission / reception device R2 when entering the inside of the monitoring area C2. The transmission / reception device R2 that has received the holder ID transmits the holder ID to the management device 1 via the communication network 2. The management apparatus 1 that has received the holder ID detects that the ID card holder 30 of the user Y has entered the monitoring area C2.

  The user Y holds the ID card 3 possessed by the user Y over the card reader CR2 and requests authentication of the entry qualification of the ID card 3. The card reader CR2 reads the identification code stored in the ID card 3 possessed by the user Y and transmits it to the access control device M2. The access control device M2 collates the identification code of the user Y read by the card reader CR2, and since the user Y does not have the qualification to enter the room B, the electric lock is not unlocked, and the management device 1 The authentication result is transmitted via the communication network 2.

  When the management apparatus 1 receives an authentication result indicating that the user Y is not permitted to enter the room B from the entrance / exit control apparatus M2, the ID card holder 30 of the user Y exists in the monitoring area C2. Confirm whether or not. As described above, the management device 1 that detects the presence of the ID card holder 30 of the user Y in the monitoring area C2 does not permit entry into the ID card holder 30 corresponding to the identification code of the ID card 3. A display command is transmitted via the transmission / reception device R2, and the entry prohibition state is displayed on the display unit 34 of the ID card holder 30 for a certain period of time.

  As a result, it is possible to clearly indicate to the surrounding users that the user Y has not received permission to enter the room B, and the user Y himself does not have the authority to enter the room B. I can recognize that.

  Next, when the user Z and the user W who are qualified to enter the room A are present in the monitoring area C1 in front of the door D1 with an electric lock, which is a predetermined area near the entrance on the shared passage side, An operation when the user Z attempts to enter the room A by operating the card before the card operation of the person W will be described.

  The ID card holder 30 possessed by the user Z transmits its own holder ID assigned to each ID card holder 30 to the transmitter / receiver R1 when entering the inside of the monitoring area C1. The transmission / reception device R1 that has received the holder ID transmits the holder ID to the management device 1 via the communication network 2. As described above, the ID card holder 30 possessed by the user Z is the ID card holder 30 corresponding to the other user A. Therefore, the management apparatus 1 that has received the holder ID detects that the ID card holder 30 of the user A has entered the monitoring area C1.

  Similarly, when the ID card holder 30 carried by the user W enters the inside of the monitoring area C1 with its own holder ID assigned to each ID card holder 30, the ID card holder 30 transmits it to the transmission / reception device R1. The transmission / reception device R1 that has received the holder ID transmits the holder ID to the management device 1 via the communication network 2. The management device 1 that has received the holder ID detects that the ID card holder 30 of the user W has entered the monitoring area C1.

  The user Z holds the ID card 3 possessed by the user Z over the card reader CR1 and requests authentication of the entry qualification of the ID card 3. The card reader CR1 reads the identification code stored in the ID card 3 possessed by the user Z and transmits it to the access control device M1. The access control device M1 collates the identification code of the user Z read by the card reader CR1, and since the user Z has the qualification to enter the room A, the electric lock is unlocked, and the management device 1 The authentication result is transmitted via the communication network 2.

  When the management apparatus 1 receives an authentication result indicating that the user Z is an authorized person entering the room A from the access control apparatus M1, the ID card holder 30 of the user Z exists in the monitoring area C1. Confirm whether or not. Here, as described above, the management device 1 detects only the presence of the ID card holder 30 corresponding to the user A and the user W in the monitoring area C1, and therefore the ID card holder 30 of the user Z Cannot confirm existence. Therefore, the management apparatus 1 transmits a display instruction for a corresponding warning to all ID card holders 30 existing in the monitoring area C1 via the communication network 2 and the transmission / reception apparatus R1.

  When the ID card holder 30 possessed by the user Z and the user W receives a response warning display command from the management apparatus 1, the ID card holder 30 displays the response warning state on the display unit 34. As a result, not only the user Z and the user W but also the surrounding users can be identified that either the user Z or the user W is an unauthorized person using the ID card holder 30 of another person. Can also notice. Therefore, the user Z can be restricted from continuing to illegally use another person's ID card holder 30.

  Next, an outline of an operation when the user W operates the card with the card reader CR1 after the display unit 34 of the ID card holder 30 of the user Z and the user W enters the correspondence warning state will be described.

  The user W holds the ID card 3 possessed by the user W over the card reader CR1 and requests authentication of the entry qualification of the ID card 3. The card reader CR1 reads the identification code stored in the ID card 3 possessed by the user W and transmits it to the access control device M1. The access control device M1 collates the identification code of the user W read by the card reader CR1, and since the user W is qualified to enter the room A, the electric lock is unlocked and the management device 1 The authentication result is transmitted via the communication network 2.

  When the management apparatus 1 receives an authentication result indicating that the user W is an authorized person to enter the room A from the entrance / exit control apparatus M1, the ID card holder 30 of the user W exists in the monitoring area C1. Confirm whether or not. As described above, the management device 1 that has detected the presence of the ID card holder 30 of the user W in the monitoring area C1 transmits a display instruction for entering the room to the ID card holder 30 of the user W. The information is transmitted via R1, the corresponding warning state is turned off on the display unit 34 of the ID card holder 30, and the room entry permission state is displayed for a certain period of time.

  Thus, the user W can release the corresponding warning state by card operation. Therefore, the release operation by the administrator or the like is not required to release the corresponding warning state of the ID card holder 30, so the management load when operating this access control system can be reduced. Further, since the correspondence warning state of the user W has been released, the fact that the person who illegally uses the other person's ID card holder 30 in the monitoring area C1 is the user Z, Not only the person W but also the surrounding users can notice.

  Next, when the user Z and the user W who are qualified to enter the room A are present in the monitoring area C1 in front of the door D1 with an electric lock, which is a predetermined area near the entrance on the shared passage side, An operation when the user Z operates the card after the card operation of the user W will be described. At this time, it is assumed that the user W remains in the monitoring area C1 even after the card operation.

  Similarly to the above case, when the ID card holder 30 possessed by the user Z and the user W enters the monitoring area C1, the management device 1 allows the ID card holders 30 of the user A and the user W to be It detects that it entered the inside of the monitoring area C1.

  When the user W operates the card, the access control apparatus M1 transmits the authentication result of the user W to the management apparatus 1 via the communication network 2. When the management device 1 receives the authentication result from the access control device M1, the management device 1 confirms that the ID card holder 30 of the user Z exists in the monitoring area C1, and based on the authentication result, the ID of the user W A display instruction for entering the room is transmitted to the card holder 30.

  When the user Z operates the card after the card operation of the user W, the access control apparatus M1 transmits the authentication result of the user W to the management apparatus 1 via the communication network 2. The management device 1 detects only the presence of the ID card holder 30 corresponding to the user A and the user W in the monitoring area C1, and cannot confirm the presence of the ID card holder 30 corresponding to the user Z. . Therefore, the management apparatus 1 transmits a display instruction for a corresponding warning to all ID card holders 30 existing in the monitoring area C1 via the communication network 2 and the transmission / reception apparatus R1.

  When the ID card holder 30 possessed by the user Z receives a response warning display command from the management device 1, the ID card holder 30 displays the response warning state on the display unit 34. On the other hand, when the ID card holder 30 possessed by the user W who has been permitted to enter the room first receives a response warning display command from the management apparatus 1, the ID warning is displayed on the display unit 34 for a certain period of time.

  Thereby, the user Z, the user W, and the surrounding user can recognize that the user Z is a person who uses the ID card holder 30 of another person illegally. In addition, the user W who has already been recognized as possessing his / her ID card holder 30 by the card operation automatically responds to a warning state after a certain period of time without performing the card operation again. Can be canceled.

  Next, each component in the access control system of a present Example is demonstrated in detail with reference to FIGS. 2-6, FIG.

  In the following description, the doors D1, D2 with electric locks are collectively referred to as doors D with electric locks, the card readers CR1, CR2 are collectively referred to as card readers CR, and the access control devices M1, M2 are collectively referred to. Is referred to as the access control device M, and the transmission / reception devices R1 and R2 are collectively referred to as the transmission / reception device R.

  In addition, in the structure of FIG. 1, the entrance / exit control apparatus M is provided for every door D with an electric lock. However, one access control device M may be configured to centrally manage a plurality of doors D with electric locks.

  FIG. 4 shows the configuration of the management apparatus 1. The management device 1 has a computer function and is connected to the communication network 2 and connected to the communication network 2 and a control unit 40 configured by an MPU, a storage unit 41 that stores management information, processing programs, various parameters, data, and the like. A LAN communication I / F 42 that communicates with the access control device M and the transmission / reception device R is provided.

  The storage unit 41 stores a holder state table 46 and a monitoring area table 47 as management information.

  As shown in FIG. 5, the holder state table 46 includes a holder ID that can individually identify each ID card holder 30, an identification code of a user that has been lent to each ID card holder 30, and each ID card holder 30. It is a table which matches a holder state and the identification name of the monitoring area | region where each ID card holder 30 was detected. The correspondence between each ID card holder 30 and the user's identification code is registered by the administrator when the ID card holder 30 is lent to the user.

  The holder state includes “normal state”, “room entry permitted state”, “room entry not permitted state”, and “corresponding warning state”. The “normal state” is a state given to the ID card holder 30 possessed by the user who has entered the room normally. The “room entry permission state” is a state given to the ID card holder 30 possessed by the user who is determined to be authenticated by the card operation and permitted to enter the room, and returns to the normal state after a certain period of time. The “room entry not permitted state” is a state given to the ID card holder 30 possessed by the user who is determined to be authenticated NG by the card operation and is not permitted to enter the room, and returns to the normal state after a certain period of time. The “corresponding warning state” is a state given to the ID card holder 30 that is suspected of having a correspondence relationship between the ID card 3 and the ID card holder 30 that is different from the correspondence relationship registered in advance.

  A plurality of holder states can be registered in the holder state field of the holder state table 46. For example, as shown in FIG. 5, there are two registered states of the ID card holder 30 whose holder ID is “H101”: “room entry permission state” and “response warning state”.

  As shown in FIG. 6, the monitoring area table 47 includes an address code of each transmitting / receiving apparatus R, an identification name of the monitoring area C monitored by each transmitting / receiving apparatus R, and a door D with an electric lock in front of each monitoring area. It is a table which matches the address code of the card reader CR for unlocking.

  The control unit 40 is configured to update the holder state table 46 and the monitoring area table 47 of the storage unit 41 from information from the access control device M and the transmission / reception device R, and the ID card holder 30 via the transmission / reception device R. Display control means 44 for controlling the display of the holder state.

  The determination unit 43 updates the holder state of the holder state table 46 based on the authentication result received from the access control device M via the LAN communication I / F 42 and the monitoring area C where the corresponding ID card holder 30 is detected. . That is, if the authentication result received from the entry / exit control device M is the identification code of the user who has been authenticated, and the corresponding ID card holder 30 is located in the same monitoring area C, the corresponding in the holder state table 46 The holder state corresponding to the user's identification code is updated to the room entry permission state. On the other hand, if the authentication result received from the entry / exit control device M is the identification code of the user who is authenticated NG, the holder status corresponding to the corresponding user identification code in the holder status table 46 is updated to the entry prohibition status. .

  The determination unit 43 receives information detected by the transmission / reception device R that the ID card holder 30 has entered or exited the monitoring area C via the LAN communication I / F 42, and the monitoring detected by the holder state table 46. The area identifier is registered.

  In addition, the determination unit 43 has the ID card holder 30 corresponding to the user identification code included in the authentication result received from the access control apparatus M within the monitoring area C corresponding to the card reader CR that has read the identification code. Determine if it exists. If the ID card holder 30 corresponding to the identification code does not exist in the monitoring area C, the holder state of the holder state table 46 is set to the corresponding warning state for all the ID card holders 30 existing in the monitoring area C. Update. At this time, if the holder state of the ID card holder 30 is a room entry permission state or a room entry non-permission state, the determination unit 43 sets the corresponding warning state for a predetermined time.

  The display control means 44 always refers to the holder state table 46 and controls the display unit 34 of the ID card holder 30 whose state has changed via the LAN communication I / F and the transmitting / receiving device R when the holder state changes. For example, when the holder state changes from the normal state to the room entry permission state, a room entry permission display command is transmitted to the ID card holder 30. Alternatively, when the normal state is changed to the corresponding warning state, a warning display command is transmitted to the ID card holder 30.

  Next, the transmission / reception device R is wired to the management device 1 and has an interface that wirelessly communicates with the communication I / F 33 of the ID card holder 30, and the display command from the management device 1 and the ID card holder 30 Relay signals such as holder ID. Further, when the ID card holder 30 enters the monitoring area C in the vicinity of the entrance / exit, the transmission / reception device R starts wireless communication, and the ID card holder 30 enters the monitoring area C when wireless communication with the ID card holder 30 has been made. It is determined that the ID card holder 30 is out of the monitoring area C when wireless communication is disabled, and a detection signal of the ID card holder 30 is transmitted to the management device 1.

The ID card holder 30 is attached to a user's clothes or the like so that other users can visually recognize the display unit 34 by a clip 39 attached to the upper part of the ID card holder 30.

  FIG. 3 shows the configuration of the ID card holder 30. The ID card holder 30 has a computer function, and is configured by an MPU or the like to control the entire ID card holder 30, a holder ID for identifying each ID card holder 30, a processing program, various parameters, and the like Is stored, a communication I / F 33 for wirelessly communicating with the transmission / reception device R, and a display unit 34 including LEDs and the like.

  The ID card 3 is a non-contact IC card that stores an identification code that can identify a carrying user. Note that any card such as a magnetic card or a wireless tag may be used as long as it can identify the user. From the viewpoint of system convenience, a non-contact type IC card is used in this embodiment.

  Next, processing of the access control system will be described with reference to the flowcharts of FIGS.

  First, processing performed by the access control apparatus M will be described with reference to the flowchart of FIG. As shown in FIG. 7, the control unit 20 of the access control apparatus M determines whether an authentication request is received from the card reader CR (S10). If the authentication request has not been received (S10-No), step S10 is repeated. When the user performs a card operation, the card reader CR reads the identification code and transmits it to the control device M, thereby determining Yes in step S10. And the determination means 23 collates the identification code contained in an authentication request (S12). Here, the determination unit 23 refers to the ID table 26 of the storage unit 21 and collates whether or not the received identification code is registered.

  If an identification code that matches the received identification code is registered in the ID table 26 (step S14-Yes), the authentication result is OK, and unlocking permission processing is performed (S16). In the unlocking permission process, the access control device M performs unlocking control. In the unlock control, the electric lock control means 24 functions and an unlock signal is sent to the door D with the electric lock. In the door D with the electric lock, the electric lock is unlocked according to the unlock signal. Further, the control unit 20 sends an authentication result to the management apparatus 1 via the LAN communication I / F 22. When the unlocking permission process is performed in S16, the process proceeds to END, and the process of the access control apparatus M is terminated.

  If the received identification code does not match the identification code in the ID table 26 in step S12, the authentication result is NG (S14-No), and unlocking disapproval processing is performed (S18). In the unlocking disapproval process, the electric lock is not unlocked, and the authentication result is transmitted to the management apparatus 1 by the control unit 20 via the LAN communication I / F 22. When the unlocking disapproval process is performed in S18, the process proceeds to END, and the process of the access control apparatus M is terminated.

  Next, processing performed in the management apparatus 1 will be described with reference to the flowcharts of FIGS. FIG. 8 is a flowchart showing processing in the management apparatus 1 that has detected the ID card holder 30 in the monitoring area C.

  The management device 1 performs the following detection process of the ID card holder 30 in the determination unit 43. When the ID card holder 30 enters the monitoring area C that is a range in which communication with the transmission / reception device R is possible, the ID card holder 30 transmits its own holder ID to the transmission / reception device R. The transmission / reception device R that has received the holder ID transmits the holder ID and the address code of the transmission / reception device R itself as a detection signal to the management device 1. When the management device 1 receives the detection signal, the determination unit 43 refers to the monitoring region table 47 stored in the storage unit 41, and monitors the monitoring region C corresponding to the address code of the transmission / reception device R included in the detection signal. It is determined that the ID card holder 30 corresponding to the holder ID included in the detection signal is detected.

  When the ID card holder 30 is detected in the monitoring area C, an approach process is performed (S20). In the entry process, the determination unit 43 refers to the holder state table 46 and writes the identification name of the detected monitoring area C in the detected monitoring area field of the detected holder ID.

  When the entry process is performed in step S22, the determination unit 43 continues to determine whether or not the ID card holder 30 has moved out of the detected monitoring area C (S22). That is, the determination unit 43 monitors the communication state between the transmission / reception device R and the ID card holder 30, and determines that the ID card holder 30 has moved to the outside of the monitoring area C when communication between the two is interrupted. Specifically, the determination unit 43 periodically polls the ID card holder 30 via the transmission / reception device R, and if the response from the ID card holder 30 is not obtained, the ID card holder 30 is in the monitoring area C. It is determined that it has moved outside. Alternatively, when the transmission / reception device R periodically polls the ID card holder 30 and the response from the ID card holder 30 cannot be obtained, the determination unit 43 transmits the result to the management device 1 to thereby determine the determination unit 43. It may be determined that the ID card holder 30 has moved outside the monitoring area C.

  When it is determined that the ID card holder 30 has moved out of the detected monitoring area C (S22-Yes), an exit process is performed (S24). In the leaving process, the determination unit 43 refers to the holder state table 46 and clears the detected monitoring area field in the holder ID of the ID card holder 30.

  When the exit process is performed in S24, the process proceeds to END and the process is terminated.

  FIG. 9 is a flowchart showing processing in the management apparatus 1 that has received the authentication result from the access control apparatus M.

  When receiving the authentication result from the access control apparatus M, the determination means 43 determines that the ID card holder 30 corresponding to the user identification code included in the authentication result is in the monitoring area C near the card reader CR included in the authentication result. It is determined whether or not it exists (S30). That is, the determination unit 43 reads the address code of the card reader CR from the authentication result, and reads the identification name of the monitoring area C corresponding to the address code by referring to the monitoring area table 47. Then, the determination unit 43 refers to the holder state table 46 to determine whether or not there is a holder ID corresponding to the identification code read from the authentication result in the monitoring area C.

  If it is determined that the ID card holder 30 corresponding to the identification code included in the authentication result does not exist in the monitoring area C near the card reader CR included in the authentication result (S30-No), the corresponding warning state is entered. The migration process is performed (S32). In the transition process to the corresponding warning state, the determination unit 34 refers to the holder state table 46 and sets the holder state fields of all ID card holders 30 existing in the monitoring area C as “corresponding warning state”. Update. Moreover, the display control means 44 always refers to the holder state table 46, and reads the identification name of the detected monitoring area of the record corresponding to the holder ID. Next, the display control unit 44 refers to the monitoring area table 47, reads the address code of the transmission / reception device R corresponding to the read identification name of the monitoring area, and reads the address code of the read address code via the LAN communication I / F 42. A “response warning display command” addressed to the ID card holder 30 of the holder ID is transmitted to the transmission / reception device R. The transmission / reception device R that has received the response warning display command from the management device 1 confirms the destination holder ID and transmits a “response warning display command” to the ID card holder 30 of the holder ID.

  When it is determined in step S30 that the ID card holder 30 corresponding to the identification code included in the authentication result is present in the monitoring area C in the vicinity of the card reader CR included in the authentication result, (S30-Yes) ), It is determined whether or not the authentication result received from the access control apparatus M is authentication OK (S34). When it determines with an authentication result being authentication OK (S34-Yes), the transfer process to an entrance permission state is performed (S36). In the transition processing to the room entry permission state, the determination unit 43 refers to the holder state table 46 and sets the holder state field of the record corresponding to the user identification code determined to be authentication OK in step S34 to “room entry permission state”. Update to. Then, the display control means 44 transmits a “room entry permission display command” to the ID card holder 30 of the holder ID corresponding to the identification code via the LAN communication I / F 42.

  Here, the display controller 44 specifically performs the following processing. First, the display control unit 44 reads out the holder ID corresponding to the identification code of the user determined to be authenticated OK in step S34 and the detected identification name of the monitoring area C. Next, the display control unit 44 refers to the monitoring area table 47 and reads the address code of the transmission / reception device R corresponding to the read identification name of the monitoring area C. Finally, the display control means 44 transmits a “room entry permission display command” addressed to the ID card holder 30 of the holder ID to the address code transmitting / receiving device R via the LAN communication I / F 42. The transmission / reception device R that has received the entry permission display command from the management device 1 confirms the destination holder ID and transmits a “room entry permission display command” to the ID card holder 30 of the holder ID. .

  When it determines with an authentication result being authentication NG in step S34 (S34-No), the transfer process to an entrance prohibition state is performed (S38). In the transition processing to the entry prohibition state, the determination unit 43 refers to the holder state table 46 and sets the holder state field of the record corresponding to the identification code of the user determined to be authentication NG in step S34 as “no entry into room”. Update to "Status". Then, the display control means 44 transmits a “room entry non-permission display command” to the ID card holder 30 of the holder ID corresponding to the identification code via the LAN communication I / F 42. The transmission / reception device R that has received the display instruction not permitting entry from the management device 1 confirms the holder ID as a destination, and issues a “display instruction not permitting entry” to the ID card holder 30 of the holder ID. Send.

  When the transition process to the corresponding warning state is performed in step S32, the transition process to the entry permission state is performed in step S36, or the transition process to the entry prohibition state is performed in step S38. Proceed to END and end the process.

Next, processing performed in the ID card holder 30 in the normal state will be described with reference to the flowchart of FIG.
As shown in FIG. 10, the control unit 31 of the ID card holder 30 determines whether or not the ID card holder 30 has moved to the inside of the monitoring area C (S60). That is, the control unit 31 monitors the state of communication with the transmission / reception device R, and determines that the ID card holder 30 has moved to the inside of the monitoring area C when communication with the transmission / reception device R is started.

  When it is determined that the ID card holder 30 has moved to the inside of the monitoring area C (S60-Yes), an entry process is performed (S62). In the approach process, the control unit 31 transmits the holder ID stored in the storage unit 32 to the transmission / reception device R, and sets the in-monitoring area flag stored in the storage unit 32 to ON. If the ID card holder 30 does not move inside the monitoring area C (S60-No), the process of step S60 is repeated.

  In response to the flag in the monitoring area being turned ON, the control unit 31 determines whether or not a holder state display command has been received from the transmission / reception device R (S64). Without receiving the holder state display command from the transmission / reception device R (S64-No), the process of steps S64 and S66 is repeated while the movement outside the monitoring area C is not determined (S66-No).

  On the other hand, when the display command of the holder state is not received from the transmission / reception device R (S64-No) and the movement outside the monitoring area C is determined (S66-Yes), the exit process is performed (S68). In the exit process, the control unit 31 turns off the monitoring area flag stored in the storage unit 32. When the exit process is performed, the process returns to step S60.

  If it is determined in step 64 that a display command for the holder state has been received (S64-Yes), the control unit 31 determines whether the display command is a “display command for permitting entry” (S70). . When the change information is “display instruction for entry permission” (S70-Yes), the flag indicating the entry permission state stored in the storage unit 32 is turned ON, and the “entry permission state” is displayed on the display unit 34. The lamp representing is turned on (S72).

  When the display instruction of the holder state received in step 64 is “display instruction not permitting entry” (S70-No, S74-Yes), the control unit 31 stores the entry prohibition state stored in the storage unit 32. Is turned on, and a lamp indicating "room entry not permitted" is lit on the display unit 34 (S76).

  When the holder state display command received in step 64 is a “response warning display command” (S70-No, S74-No), the control unit 35 indicates the corresponding warning state stored in the storage unit 32. The flag is turned ON, and a lamp indicating “corresponding warning state” is lit on the display unit 34 (S78).

  In step S72, step S76, and step S78, when the lamps representing the respective states are turned on, the process is terminated.

  Next, processing performed in the ID card holder 30 when the current holder state is the “response warning state” will be described with reference to the flowchart of FIG. 11.

  As shown in FIG. 11, whether or not the control unit 31 of the ID card holder 30 has received a “room entry permission display command” or a “room entry permission display command” from the management device 1 via the transmission / reception device R. Is continuously determined (S80).

  If the control unit 31 determines that it has received a “room entry permission display command” or a “room entry non-permission display command” (S80—Yes), it performs a release process (S82). In the release process, the control unit 31 turns off the flag indicating the corresponding warning state stored in the storage unit 32 and causes the display unit 34 to turn off the lamp indicating the “corresponding warning state”. When the display command received in step S80 is a “room entry permission display command”, the flag indicating the room entry permission state is turned ON, and the lamp indicating the “room entry permission state” is turned on on the display unit 34. . On the other hand, if the display command received in step S80 is a “display command not permitting room entry”, a flag indicating that the room is not allowed is turned ON, and a lamp indicating “room not allowed to enter” is displayed on the display unit 34. Lights up.

  When the release process is performed in step S82, the process proceeds to END and the process is terminated.

  Next, a process performed in the ID card holder 30 when the current holder state is “a room entry permission state” or “a room entry permission state” will be described with reference to the flowchart of FIG.

  As shown in FIG. 12, the control unit 31 of the ID card holder 30 starts a timer when the “entry-permitted state” or “entry-rejected state” is entered, and the timer is stored in the storage unit 32 of the ID card holder 30. It is determined whether or not the lamp lighting time stored in is exceeded (S90).

  When it determines with the timer having exceeded lamp lighting time (S90-Yes), the control part 31 performs the transfer process to a normal state (S92). In the transition process to the normal state, the control unit 31 turns off the flag indicating the room entry permission state or the room entry non-permission state stored in the storage unit 32, and displays the “room entry permission state” or “room entry” on the display unit 34. Turn off the lamp indicating “not allowed”.

  While it is determined in step S90 that the timer does not exceed the lamp lighting time (S90-No), the control unit 31 sends a “response warning display command” from the management device 1 via the transmission / reception device R. Is determined (S94).

  If the control unit 31 determines that the “response warning display command” is not received (S94—No), the control unit 31 returns to step S90. When determining that the “response warning display command” has been received (S94—Yes), the control unit 31 performs a transition process to the response warning state (S96). In the transition processing to the corresponding warning state, the control unit 31 turns on the flag indicating the corresponding warning state stored in the storage unit 32 for a certain period of time, and sets the lamp indicating the “corresponding warning state” to the display unit 34. Turn on for hours.

  When the transition process to the normal state is performed in step S92, the process proceeds to END and the process is terminated.
