Description

  The present invention relates to a room management system and a room management method for managing a room by controlling electric locks and sensors installed in the room.

  Conventionally, a room management system for managing the entrance / exit of each room of a building and the security state has been proposed. Such a system includes, for example, an IC card that stores verification data for identifying an individual, a card reader that is provided in a room to be managed and reads the verification data from the IC card, and an electric lock provided on a door of the room. , A sensor for detecting the state of the room, and master data indicating verification data of a person permitted to enter each card reader is stored, and whether the verification data read by the card reader exists in the master data. And a controller for confirming whether or not. When the verification data is read from the IC card by the card reader, the controller unlocks the electric lock if the verification data exists in the master data, and does not unlock the electric lock if the verification data does not exist in the master data. . The controller recognizes the state of the room based on information detected by the sensor.

  In such a room management system, a system has been proposed in which not only an actual room but also a partition provided between rooms is removed, and a combined area of a plurality of rooms is managed as a virtual room ( For example, see Patent Document 1.) In this system, the relationship between a single room and a room from which the partition is removed is defined and stored in the controller when the partition exists and when the partition does not exist. Thereby, even if it is a case where a partition is changed, management of each room of a building can be performed, without changing the database of a controller significantly.

JP 2001-167159 A

  However, since the number of terminal devices such as card readers, electric locks, and sensors that can be connected to one controller is physically limited, for example, a large room has many rooms in one large room due to many partitions. In such a case, a single controller cannot provide a large number of terminal devices, so a complicated system must be designed or a large-scale controller must be provided, which is laborious and expensive. .

  Accordingly, an object of the present invention is to provide a room management system and a room management method capable of easily managing an arbitrary space such as a room even when a large number of terminal devices are provided.

  In order to solve the problems as described above, a room management system according to the present invention includes a plurality of terminal devices arranged for each predetermined area in an arbitrary space, and management set by being connected to the terminal devices. By controlling the terminal device according to the state, each comprises a plurality of controllers that manage at least one area, a communication line that connects these controllers to each other, and a storage unit that stores a parent-child relationship between the areas, The controller is characterized by changing the management state of the area based on the parent-child relationship between the areas.

  In the room management system, the controller that manages the parent area changes the management state of the parent area when requested to change the management state of the parent area or to change the management state of the child area. And a first notification that transmits a request to change the management status of the child area to the controller that manages the child area when the management status of the parent area is changed by the first changing means. And a controller that manages the child area includes a second changing means that changes the management state of the child area to the same management state as the parent area when receiving the change instruction request. May be.

  In the room management system, when a change in the management state of the child area is requested, the controller that manages the child area requests the controller that manages the parent area to change the management state of the child area. A second notifying unit that transmits a request request may be further provided, and the first changing unit may change the management state of the parent region based on the change request request.

  Moreover, the room management method according to the present invention controls a terminal device according to a set management state, connected to the terminal device, and a plurality of terminal devices arranged for each predetermined area in an arbitrary space. Accordingly, each controller includes a plurality of controllers that manage at least one area, a communication line that connects these controllers to each other, and a storage unit that stores a parent-child relationship between the areas. And a step of changing the management state of the area.

  According to the present invention, a plurality of controllers each managing at least one area are provided, and the management state set for the area is changed based on the parent-child relationship between the areas, so that it is provided in an arbitrary space. It becomes easy to manage a large number of terminal devices with a plurality of controllers, and as a result, it is possible to easily manage an arbitrary space.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[Configuration of room management system]
As shown in FIG. 1, the room management system according to the present embodiment monitors the inside of the large room R based on the controllers 1a to 1c for managing the state in the large room R and the information received from the controllers 1a to 1c. And a network 3 connecting the controllers 1a to 1c and the central monitoring device 2.

  The controllers 1a to 1c are connected to a sensor 4 for detecting an intruder into an installed area, an electric lock 5 for locking and unlocking a door, and a card reader 6 for reading verification data from a card possessed by a user. Yes. As a result, the controllers 1a to 1c enable the security states of the corresponding areas 10a to 10c in the large room R in which the sensor 4, the electric lock 5 and the card reader 6 are disposed, the locking and unlocking of the electric lock 5, and the passage mode. Manage the settings etc. In FIG. 1, each of the controllers 1a to 1c is provided with one sensor 4, one electric lock 5 and one card reader 6, but these quantities are limited by the size of the large room R and the limits of the controllers 1a to 1c. Can be set freely as appropriate. Therefore, the state of a plurality of areas may be managed by one controller.

  Here, in the area in the large room R, a parent-child relationship, in other words, an upper and lower relationship with another area is set in advance. For one large room R, one parent region is set, and the other regions are set as children. In the present embodiment, the area 10a managed by the controller 1a is set in advance as a parent (upper), and the areas 10b and 10c managed by the other controllers 1b and 1c are set as children (lower). Such a parent-child relationship is stored in the storage unit 14 of the controllers 1a to 1c described later.

[Controller configuration]
Each of the controllers 1a to 1c has an equivalent configuration, and includes a reception unit 11, a change unit 12, a request unit 13, a storage unit 14, and a management unit 15, as illustrated in FIG.

  The accepting unit 11 receives a change request request indicating that a change in the management state of the predetermined area is requested from a user or another controller via the network 3 or a change indicating that a change in the management state of the predetermined area is instructed. An instruction request is accepted.

  The change unit 12 changes the management state set in the state table 14b of the storage unit 14 to be described later when the change request request or the change instruction request is received by the reception unit 11.

  When the changing unit 12 changes the management state of the parent area, the requesting unit 13 transmits a change instruction request that instructs the child area to change the management state of the child area.

  The storage unit 14 includes a relationship table 14a, a state table 14b, and a permission table 14c.

  In the relationship table 14a, the parent-child relationship of the area in the large room R is recorded. In the present embodiment, a case where each controller 1a to 1c has a relation table 14a will be described as an example.

  In the status table 14b, the management status of the area managed by the own device is recorded. This management state includes a security state and a traffic mode. The guarded state means the guarded state of the areas 10a to 10c, and there are “warning” and “non-warning” states. The passage mode means the state of the unlocking operation of the electric lock 5 associated with the card reader 6 when entering and leaving the room with a card. The state of continuous unlocking, the state of temporarily unlocking, the passage There are states that make it impossible.

  In the permission table 14c, collation data of a user's card that is permitted to enter an area managed by the controller of the own device is recorded.

  The management unit 15 manages the corresponding areas 10a to 10c based on the state of the state table 14b and controls the management state.

  Regarding management of the corresponding areas 10a to 10c, specifically, the management unit 15 responds when the electric lock 5 is unlocked or the sensor 4 reacts when the guard state is in the alert state. When an intrusion into 10a to 10c is detected, the central monitoring device 2 is notified of the occurrence of the intrusion. In addition, when the card collation data is read by the card reader 6, the management unit 15 checks whether or not the collation data exists in the management table 14c, and if it exists in the management table 14c, the corresponding electric lock 5 is present. Is unlocked, and the corresponding electric lock 5 is not unlocked if it does not exist in the management table 14c.

  Regarding the control of the management state, when the controller of the own device manages the parent area, when the management state of the parent area is changed, the management unit 15 causes the changing unit 12 to change the management state of the parent area. . On the other hand, when the controller of the own device manages the child area, when changing the management state of the child area, the management unit 15 sends a change request request to the controller that manages the parent area by the request unit 13. Send it.

[Operation of management status in room management system]
Next, the management state changing operation in the room management system according to the present embodiment will be described.

(When the management status is requested from the parent area)
First, with reference to FIG. 3, a management state change operation when a change in management state is requested from the parent area 10a will be described. FIG. 3 schematically shows FIG. 1. In FIG. 3, the controllers 1 a to 1 c manage the regions 10 a to 10 c associated with each other, that is, for example, a sensor (not shown), an electric The terminals 10a to 10c are managed by being connected to terminal devices arranged in corresponding areas such as locks and card readers, and exchanging output signals with these.

  When the management unit 15 requests the changing unit 12 to change the management state (Step S1), the controller 1a refers to the relationship table 14a of the storage unit 14 by the receiving unit 11 and the region 10a is a parent region or Check if it is one of the child areas.

  When it is confirmed that the area 10a is a parent area, the controller 1a changes the management state of the parent area 10a recorded in the state table 14b by the changing unit 12 (step S2).

  Here, the management unit 15 requests the change unit 12 to change the management state based on, for example, a collation operation on the card reader 6, schedule control, event control, and operation from the central monitoring device 2. For example, when the change request relates to the security state, the management state is changed to “warning” or “non-warning”.

  For example, when the security status of the area 10a is “alarming” and the control for changing the security status to “non-alarming” is performed, the controller 1a records the status in the status table 14b by the changing unit 12. The guard state of the parental area 10a is changed from “warning” to “non-warning”.

  When the management state is changed, the controller 1 a detects the controllers 1 b and 1 c managing the child areas 10 b and 10 c from the relation table 14 a of the storage unit 14 by the request unit 13, and sends a change instruction request to the controller 1 via the network 3. It transmits to 1b and 1c (step S3). The change instruction request includes at least information regarding the changed management state. For example, when the security state is changed from “warning” to “non-warning”, the change instruction request includes an instruction to change the security state to “non-warning”.

  When the controller 1b, 1c receives the change instruction request from the controller 1a via the network 3 by the receiving unit 11, the controller 12b, 10c stores the child areas 10b, 10c recorded in the state table 14b based on the change instruction request. The management state is changed (step S4). For example, when receiving a change instruction request for changing the security state to “non-warning”, the controllers 1b and 1c change the security status of the child areas 10b and 10c recorded in the status table 14b by the changing unit 12. , Change from “warning” to “non-warning”. As a result, the management state of the child areas 10b and 10c is changed to the same state as that of the parent area 10a.

(When a change of management status is requested from a child area)
Next, with reference to FIG. 4, a management state change operation when a change in management state is requested from a child area will be described. In FIG. 4, as in the case of FIG. 3, the controllers 1 a to 1 c are assumed to manage the areas 10 a to 10 c associated with each other.

  For example, when the management unit 15 requests the change unit 12 to change the management state (step S11), the controller 1b refers to the relationship table 14a of the storage unit 14 by the reception unit 11 and the region 10b is the parent. Check whether it is an area or a child area.

  When it is confirmed that the area 10b is a child area, the controller 1b detects the controller 1a that manages the parent area 10a from the relation table 14a by the request unit 13, and notifies the change request based on the change instruction request. Is transmitted to the controller 1a managing the parent area 10a via the network 3 (step S12). For example, when the security state of the area 10b is “warning” and the control for changing the security state to “non-warning” is performed, the controller 1b changes the security state of the child area 10b to A change request request for changing from “warning” to “non-warning” is transmitted to the controller 1a.

  When the accepting unit 11 accepts the change request request from the controller 1b, the controller 1a changes the management state of the parent area 10a recorded in the state table 14b based on the change request request by the changing unit 12 (step S13). . For example, when receiving a change instruction request for changing the security state to “non-alarming”, the controller 1a changes the security status of the parent area 10a recorded in the status table 14b by the changing unit 12 to “already being alerted”. To "Non-warning".

  When the management state is changed, the controller 1a detects the controllers 1b and 1c that manage the child areas 10b and 10c from the relation table 14a of the storage unit 14, and the change unit 13 sends a change instruction request to the controller via the network 3. It transmits to 1b and 1c (step S14). For example, if the security status is changed from "Warning" to "Non-Warning", the change mode is changed from "Linked" to "No Linked". In this case, the change instruction request includes an instruction to change the interlocking mode to “no interlocking”.

  When the controller 1b, 1c receives the change instruction request from the controller 1a via the network 3 by the receiving unit 11, the controller 12b, 10c stores the child areas 10b, 10c recorded in the state table 14b based on the change instruction request. The management state is changed (step S15). For example, when receiving a change instruction request for changing the security state to “non-warning”, the controllers 1b and 1c change the security status of the child areas 10b and 10c recorded in the status table 14b by the changing unit 12. , Change from “warning” to “non-warning”. Thereby, the management state of the area 10b is changed to a state corresponding to the change request. Further, the areas 10a to 10c are set to the same management state.

  Thus, according to the present embodiment, it is connected to a terminal device such as the sensor 4, the electric lock 5 and the card reader 6 installed in each of the areas 10a to 10c of the large room R, and manages at least one area. By providing a plurality of controllers 1a to 1c and changing the management state of each region based on the parent-child relationship between the regions by these controllers 1a to 1c, a large number of terminal devices provided in the large room R are connected to the plurality of controllers 1a. ˜1c can be easily managed, and as a result, the large room R can be easily managed. In this way, the large room R is managed by forming one management unit for each area, setting a parent-child relationship between the areas, and synchronizing the management state of the child area to the management state of the parent area. It is possible to set a room for at least one area, and it is possible to easily change partitioning.

  According to the present embodiment, for example, since the management states of the areas 10a to 10c of the large room R shown in FIG. 1 are synchronized, the management state of the area 10a = the management state of the area 10b = the management state of the area 10c = The relationship of the management state of the large room R is established. Therefore, on the human interface of the central monitoring device 2, the management state of the parent area 10a can be used as the management state of the large room R. Here, when the management state of the security status is “alarming” in the area 10a, the security status of the areas 10b and 10c is also “alarming”, so that the sensor 4 in the area 10b reacts or the electric lock 5 in the area 10c. Or the like, the central monitoring device 2 detects that a suspicious person has entered the large room R. At this time, the management state such as the security state requires control between the controllers via the network 3, but the intrusion detection itself is control for each controller. Also, the method of intrusion detection does not depend on management state synchronization. As described above, in this embodiment, the room can be managed by the same method as the conventional method except for the synchronization of the management state, so that the management control distributed in units of controllers can be realized.

  Forming one management unit across the controllers via the network 3 means that, for example, the controller that performs intrusion monitoring collects the states of the sensors 4 connected to other controllers one by one via the network 3. It is also possible by the method. However, in this method, since it is necessary to collect the state of the sensor 4 in real time, the communication load of the network 3 increases. Further, when communication via the network 3 becomes impossible, intrusion monitoring cannot be performed. In addition, since the state of the sensor 4 must be collected one by one, the load of calculation processing of each controller increases.

  On the other hand, in the present embodiment, the network 3 is used only for management state synchronization, so the communication load is small. In addition, since management such as intrusion monitoring is performed in units of controllers, each area can be managed even if communication via the network 3 becomes impossible. Moreover, since the room is managed by the same method as the conventional method except for the synchronization of the management state, the calculation load is small.

  In the present embodiment, when the management state is changed, the management state of the parent area is always changed, so that the management state of the parent area is always the latest state. Therefore, the child area may be matched to the management state of the parent area when the management state is different from the parent management state. This can be realized, for example, by the controller that manages the parent region notifying the controller that manages the child region of the management state of the parent region at a certain period. If the management state of the child area is different from that of the parent area according to the notification from the parent area, the child area can be synchronized with the management state of the parent by matching the management state of the parent area. On the contrary, the controller that manages the child area may collect the management state of the parent area at a certain period in the controller that manages the parent area. By doing so, the management state of the parent area and the child area can be synchronized even when a difference occurs in the management state due to disconnection of the network 3 or the like.

  In such management state synchronization, instead of changing the management state of the child area according to the parent area as in the present invention, it is also realized by linked control triggered by a state change used in equipment related movements, etc. It seems to be possible. However, synchronization triggered by a state change can be realized when the direction of synchronization is one direction, but it can be realized by multi-directional synchronization in which any one output state changes and all others are output at the same value. Difficult to do. In many cases, synchronization is performed even in the state collection at a fixed period in consideration of the disconnection of the network. For example, in FIG. 1, when communication via the network 3 is impossible, the security state of the area 10a is “warning”. "The area 10b is" non-warning "and the area 10c is" warning ". When the network 3 recovers in this state, if the information collection by the areas 10a and 10c is performed first, the areas 10a to 10c are guarded. The state becomes “non-warning”, and if the information collection by the region 10b is performed first, the security state of the regions 10a to 10c becomes “warning”. As described above, the method using the state change as a trigger is not appropriate in terms of control because the management state depends on the timing of communication return.

  In the present embodiment, the controllers 1a to 1c have the same relationship table 14a. However, if the parent-child relationship can be identified in the room management system, all the controllers 1a to 1c have the same relationship table. 14a may not be included. For example, the relationship table of the controller 1a that manages the parent area 10a records all parent-child relationships in the room management system, and the relationship table 14a of the controllers 1b and 1c that manages the child areas 10b and 10c includes Only information for identifying the controller 1a that manages the parent area 10a may be recorded. Moreover, the relationship table 14a may be provided in the central monitoring device 2, and each controller 1a-1c may identify the parent-child relationship by asking the central monitoring device 2.

  In the present embodiment, the management state is synchronized in all areas, but may not be synchronized depending on the case. For example, when there are a plurality of card readers 6 in one large room R in the management mode linked to the passing mode, the passing modes of the card readers 6 are usually the same in many cases. However, even in the same large room R, there is a case where it is not desired to be interlocked. This can be realized by the following method.

  When the controller that manages the parent area changes the passage mode, the controller sends a change instruction request to change the passage mode to the child area to be linked, and sends a change instruction request to the child area that is not to be linked. Do not send. Alternatively, a change instruction request may be transmitted to all child areas, and the controller that manages the child areas may select whether or not to change the traffic mode.

  When the controller that manages the child area changes the traffic mode, the controller that manages the parent area does not change the traffic mode of the parent area in response to the change request request from the controller, and issues a change instruction request. The data is transmitted only to the controller that manages the child area. The change instruction request may be transmitted to a controller that is not the transmission source of the change instruction request, and the controller that is not the transmission source may read and discard the request.

  By doing so, it is possible to prevent the management state from being synchronized.

  The present invention can be applied to a management system for managing buildings.
