Description

Technical Field

The present invention relates to a door lock control system and a door lock control device configured to control unlocking of each of plural door lock devices installed in associated with respective different doors.

Background Art

In the past, there has been known an electric lock system designed to control electric locks (electronic locks) constituting door lock devices provided to doors. Such an electric lock system performs personal authentication based on an authentication card preliminarily registered, and unlocks the electric lock according to an authentication result, for example.
As to the aforementioned electric lock system, to unlock the plural electric locks, the personal authentication based on the authentication card is necessary for each of the plural electric locks. Thus, there is a problem that it is troublesome for a user to perform the personal authentication based on the authentication card for each electric lock.
As means for solving the above problem, there has been known an electric lock control device capable of unlocking two or more electric locks in response to one process of reading information and authenticating the read information (see document 1 [ JP 5-321524 A ]). The electric lock control device disclosed in document 1 selects the electric lock from the plural electric locks according to the inputted information, as an unlocking object. According to the electric lock control device disclosed in document 1, it is possible to select different electric locks in response to different inputted information.
However, a system employing the electric lock control device disclosed in document 1 includes only one electric lock control device which reads the inputted information and authorizes it. Hence, it is incapable of fulfilling a request to change the electric lock designated as the unlocking object according to a location of a user.
According to the system employing the electric lock control device disclosed in document 1, irrespective of a case where a user is in front of a main entrance and a case where a use is in front of a side exit different from the main entrance, the same electric lock is selected as the electric lock designated as the unlocking object. Therefore, the electric locks should be unlocked without causing any disadvantages for both cases. However, the electric lock which is necessary to one case but is unnecessary to the other case is likely to be included in the electric locks designated as the unlocking objects. This may cause a security problem. For example, when a user is in front of the main entrance, the electric lock at the side exit is likely to be unlocked in addition to the electric lock at the main entrance.

Each of the input devices 2 is a contactless card reader (contactless key reader) configured to read personal identification information from the authentication card 6 serving as a contactless card, for example. The input devices 2 are provided to the different doors 81 to 88, respectively. In brief, the input devices 2 are installed respectively associated with the different door lock devices 1. Each of the input devices 2 includes, as shown in FIG. 1, an input unit 201 and a second communication unit 202. Individual input device identification information (key reader number) is allocated uniquely to each of the input devices 2. The input unit 201 is configured to read the personal identification information from the authentication card 6. The communication unit 202 is configured to send the personal identification information read by the input unit 201 to the control device 5 (door lock control device 3) explained below.
As shown in FIG. 2, the first input device 21 is installed on a side of the first door 81 facing the outdoor space 78. The second input device 21 reads the personal identification information from the authentication card 6 in a case where a user enters the passageway 77 from the outdoor space 78. The second input device 22 is installed on a side of the second door 82 facing the passageway 77. The second input device 22 reads the personal identification information from the authentication card 6 in a case where a user enters the reception room 75 from the passageway 77. The third input device 23 is installed on a side of the third door 83 facing the passageway 77. The third input device 23 reads the personal identification information from the authentication card 6 in a case where a user enters the second office 72 from the passageway 77. The fourth input device 24 is installed on a side of the fourth door 84 facing the passageway 77. The fourth input device 24 reads the personal identification information from the authentication card 6 in a case where a user enters the first office 71 from the passageway 77. The fifth input device 25 is installed on a side of the fifth door 85 facing the first office 71. The fifth input device 25 reads the personal identification information from the authentication card 6 in a case where a user enters the executive room 74 from the first office 71. The sixth input device 26 is installed on a side of the sixth door 86 facing the passageway 77.

The eighth input device 28 is installed on a side of the eighth door 88 facing the outdoor space 78. The eighth input device 28 reads the personal identification information from the authentication card 6 in a case where a user enters the passageway 77 from the outdoor space 78.
The door lock control device 3 shown in FIG. 1 is a software embedded device including a CPU (Central Processing Unit) and a memory, for example. The door lock control device 3 includes a storage device 4 and the control device 5. The storage device 4 is configured to store a correspondence table (correspondence relation) designating the door lock devices 1 selected as unlocking objects. The control device 5 is configured to control the respective door lock devices 1.
The storage device 4 preliminarily stores the correspondence table as shown in FIG. 3. In the correspondence table illustrated in FIG. 3, each combination of the class information ("officer", "manager", and "staff", in FIG. 3) included in the personal identification information and the input device 2 (i.e., the input device identification information) having read this personal identification information is associated with the one or more door lock devices 1 designated as the unlocking objects. In other words, the storage device 4 is configured to store the correspondence relation between the door lock device 1 and the combination of the identification information (personal identification information) and the input device 2.
The leftmost column in FIG. 3 shows the input devices 2. "Sn" (n = 1 to 8) represents the nth input device 2n (e.g., "S1" represents the first input device 21, and "S2" represents the second input device 22). The second column from the left in FIG. 3 shows the class information of a user. The uppermost row in FIG. 3 shows the door lock devices 1. "Dn" (n = 1 to 8) represents the nth door lock device In (e.g., "D1" represents the first door lock device 11, and "D2" represents the second door lock device 12). A numerical value shown in the third to tenth columns from the left in FIG. 3 represents a relocking period (the unit is "minutes") defining a period between locking time and unlocking time of the door lock device 1. Note that, a blank in FIG. 3 represents that the corresponding door lock device is not unlocked.
A priority of the unlocking authority given to a user is determined based on the class information of the user. In the instance shown in FIG. 3, the priority of the unlocking authority becomes higher in the order of "staff", "manager", and "officer". For example, when the fourth input device 24 ("S4" in FIG. 3) reads out the personal identification information indicative of "officer", the fourth door lock device 14 ("D4" in FIG. 3) and the fifth door lock device 15 ("D5" in FIG. 3) are designated as the unlocking objects and unlocking states thereof are kept for 10 minutes from the unlocking. When the fourth input device 24 reads out the personal identification information indicative of "staff", only the fourth door lock device 14 is designated as the unlocking object.
The control device 5 shown in FIG. 1 includes a communication unit 501, an authentication unit 502, a processing unit 503, a relocking timer 504, and a continuous authentication timer 505.
The communication unit 501 communicates with the plural door lock devices 1 and the plural input devices 2. The communication unit 501 receives the personal identification information (key ID) from each input device 2. For example, the communication unit 501 can uniquely identify the input device 2 selected as a communication partner by using a connection port. In this regard, the communication unit 501 outputs identification information of the connection port to the authentication unit 502 and the processing unit 503 as the input device identification information (key reader number) of the input device 2. For example, the communication unit 501 is provided with the eighth connection ports for making connection with the input devices 2. The first to eighth input devices 21 to 28 are connected to the first to eighth connection ports, respectively. In this case, the communication unit 501 (door lock control device 3) is enabled to identify the input device 2 acting as a sender of the identification information.
The authentication unit 502 analyzes the personal identification information received by the communication unit 501 to perform personal authentication. An authentication result of the authentication unit 502 is outputted to the processing unit 503. The authentication result includes the personal identification information and the input device identification information of the input device 2 which has read out this personal identification information.
The processing unit 503 refers to the correspondence table (see FIG. 3) and selects, as the unlocking object, the door lock device 1 associated with a combination of the identification information and the input device identification information included in the authentication result. In brief, processing unit 503 refers to the correspondence relation stored in the storage device 4 and selects the door lock device 1 associated with the combination of the received identification information (personal identification information) and the input device 2 which has sent this identification information (personal identification information). Upon selecting the door lock device 1 as the unlocking object, the processing unit 503 controls the communication unit 501 in such a manner to send the unlocking signal to the door lock device 1 designated as the unlocking object in order to unlock the door lock device 1 designated as the unlocking object.
After passage (a lapse) of the relocking period from the time of unlocking the door lock device 1 designated as the unlocking object, the processing unit 503 locks the door lock device 1 in the unlocked state. After sending the unlocking signal to the selected door lock device 1, the processing unit 503 searches for the relocking period from the storage device 4 based on the personal identification information used for the current unlocking. The processing unit 503 counts the relocking period obtained from the search result by use of the relocking timer 504.
The relocking timer 504 counts elapsed time from the time of unlocking until the relocking time in response to the processing of the processing unit 503. The relocking period is defined as a time period (see FIG. 3) which is selected to be sufficient to allow an authenticated user to pass through a predetermined door and to be capable of reducing the possibility that another person passes through the door without authentication. In response to an instruction from the processing unit 503, the relocking timer 504 starts to count or changes a count value, for example. When the counter shows the count value of 0, the relocking timer 504 notifies the processing unit 503 of an event where the counter shows the count value of 0.
When the relocking period has been counted by the relocking timer 504, the processing unit 503 receives, from the relocking timer 504, a notice of the event where the count value becomes zero. Thereafter, the processing unit 503 sends the locking signal to the door lock device 1 designated as the unlocking object corresponding to the personal identification information used for the current unlocking, and thus the corresponding door lock device 1 is switched to the locking state. In this manner, a user is not required to manually lock the door lock device 1. Hence, the high security level can be maintained.
Note that, the door lock control system may include the relocking timer 504 configured to count the relocking time, for each door lock device 1, and the relocking timer 504 may be provided to not the control device 5 but the door lock device 1. In this case, the control device 5 sends information indicative of the relocking period to the door lock device 1 in addition to the unlocking signal. Each of the door lock devices 1 is configured to count the relocking period by use of the relocking timer 504 provided thereto. When the relocking period has passed, the door lock device 1 locks the electric lock 101 thereof.
Besides, when plural pieces of the personal identification information are inputted into the same input device 2 within a predetermined period, the processing unit 503 of the present embodiment unlocks the door lock device 1 designated as the unlocking object which is stored in the storage device 4 in association with at least one of the plural pieces of the person identification information inputted into the input device 2.
Upon receiving the personal identification information from the input device 2, the processing unit 503 checks whether or not the continuous authentication timer 505 associated with the input device identification information of the input device 2 has been activated. When the continuous authentication timer 505 has not yet been activated, the processing unit 503 activates this continuous authentication timer 505 and stores the personal identification information received from the input device 2 as a candidate for a member of a group (continuous authentication object ID) associated with the input device 2. In contrast, when the continuous authentication timer 505 has already been activated, the processing unit 503 adds and stores the personal identification information received from the input device 2 as a candidate for a member of a group associated with the input device 2.
The continuous authentication timer 505 counts a group authentication period associated with the input device 2 in response to the processing of the processing unit 503. The group authentication period is defined as a time period (e.g., 5 seconds and 10 seconds) which is selected in consideration of a situation where plural users recognized as the same group take authentication actions continuously by use of the same input device 2. For example, when time (a group authentication interval) between the input of the previous personal identification information and the input of the next personal identification information is shorter than the group authentication period, these pieces of the personal identification information are regarded as being included in the same group. In response to an instruction from the processing unit 503, the continuous authentication timer 505 starts to count or changes a count value, for example. When the counter shows the count value of 0, the continuous authentication timer 505 notifies the processing unit 503 of an event where the counter shows the count value of 0.
The processing unit 503 receives, from the continuous authentication timer 505, a notice of the event where the count value becomes zero. In brief, the processing unit 503 checks whether or not there is the continuous authentication timer 505 which has counted the predetermined group authentication period with regard to the continuous authentication timers 505 which are currently activated. When there is the continuous authentication timer 505 which has counted the group authentication period, the processing unit 503 concludes that the members of the group corresponding to the input device 2 associated with the continuous authentication timer 505 are determined. Thereafter, based on the personal identification information of each of the determined members of the group and the input device identification information of the input device 2, the processing unit 503 obtains a union (logical sum) of sets of the door lock devices 1 designated as the unlocking objects and stored in the storage device 4 in association with the personal identification information. After obtaining the union, the processing unit 503 sends the unlocking signal to the door lock device 1 designated as the unlocking object included in the obtained union.
In other words, the control device 5 is configured to judge whether or not an event where plural pieces of the identification information (personal identification information) are inputted from the same input device 2 before passage of a predetermined period has occurred. The control device 5 is configured to, upon concluding that the event has occurred, refer to the correspondence relation stored in the storage device 4 and select the door lock device 1 associated with at least one of the plural pieces of the identification information (personal identification information) with regard to the same input device 2.
For example, when the plural pieces of the identification information (personal identification information) "officer", "manager", and "staff" are inputted into the first input device 21 within the predetermined period, the control device 5 selects the six door lock devices 11, 13 to 17 each associated with at least one of the plural pieces of the identification information (personal identification information) "officer", "manager", and "staff" with regard to the same input device 2 (first input device 21). Thus, the six doors 81, 83 to 87 respectively associated with the six door lock devices 11, 13 to 17 are unlocked.
Further, in a situation where the new personal identification information is inputted into the input device 2 after the door lock device 1 designated as the unlocking object has been unlocked, when the priority of the new personal identification information is lower than that of the previous personal identification information, the processing unit 503 of the present embodiment unlocks the door lock device 1 designated as the unlocking object stored in the storage device 4 in association with the new personal identification information. Further, the processing unit 503 locks the door lock device 1 which has been unlocked but is not associated with the new personal identification information. The priority of the unlocking authority allocated to the class information of the personal identification information is preliminarily stored in the storage device 4.
To unlock the door lock device 1 in response to another input of the personal identification information within a period when the relocking timer 504 counts the relocking period, the processing unit 503 compares the priority of the unlocking authority allocated to the class information of the personal identification information of the person who intends to unlock the desired door with the priority of the unlocking authority allocated to the class information of the personal identification information which has caused the count of the current relocking period, and determines which one is higher than the other.
In other words, upon receiving the identification information (personal identification information) from the input device 2, the processing unit 503 (control device 5) judges whether or not the predetermined period passes from the time of receiving the previous identification information (personal identification information) from the same input device 2. The predetermined period is identical to the longest one of the relocking periods of the door lock devices 1 selected according to the combinations of the input device 2 and the identification information, for example. Upon concluding that the predetermined period does not pass from the time of receiving the previous identification information (personal identification information), the processing unit 504 retrieves the priority of the present identification information (personal identification information) from the storage device 4 and compares the retrieved priority of the present identification information (personal identification information) with the priority of the previous identification information (personal identification information).
When the priority of the unlocking authority allocated to the personal identification information of the person who intends to unlock the desired door is equal to or higher than the priority of the unlocking authority allocated to the class information of the personal identification information causing the count of the current relocking period, the processing unit 503 sends the unlocking information via the communication unit 501 to the door lock device 1 identified by the personal identification information of the person who intends to unlock the desired door. When the relocking period is being counted with regard to the door lock device 1 identified by the personal identification information of the person who intends to unlock the desired door, the unlocking signal may be sent again, or the counted value of the relocking period may be initialized.
In contrast, when the priority of the unlocking authority allocated to the class information of the personal identification information causing the count of the current relocking period is higher than the priority of the unlocking authority allocated to the personal identification information of the person who intends to unlock the desired door, the processing unit 503 sends the unlocking signal, via the communication unit 501, to the door lock device 1 corresponding to the personal identification information of the person who intends to unlock the desired door, and at the same time, controls the relocking timer 504 to start to count the relocking period. With regard to the door lock devices 1 respectively corresponding to the relocking timers 504 which are counting the relocking periods, the processing unit 503 sends the locking signal via the communication unit 501 to the door lock devices 1 other than the door lock device 1 which is unlocked based on the present personal identification information.
In other words, upon concluding that the priority of the present identification information (personal identification information) is lower than the priority of the previous identification information (personal identification information), the processing unit 503 selects, as the unlocking object, the door lock device 1 associated with the present identification information (personal identification information) with regard to the same input device 2 and controls the door lock device 1 designated as the unlocking object in such a manner to unlock the corresponding door. Further, the processing unit 503 selects, as the locking object, the door lock device 1 which is associated with the previous identification information (personal identification information) but is not associated with the present identification information (personal identification information) with regard to the same input device 2 and controls the door lock device 1 designated as the locking object in such a manner to lock the corresponding door.
Besides, with regard to plural pieces of the personal identification information, the priority of the unlocking authority is allocated to a group of the personal identification information in conformity with a predetermined criterion. For example, the unlocking authority having the highest priority out of pieces of the unlocking authority allocated to pieces of class information of pieces of the personal identification information included in the group is selected as the unlocking authority of this group.
The following explanation referring to FIGS. 4 to 6 is made to an operation of the door lock control system in accordance with the present invention.
First, the control device 5 receives, from the input device 2, the key reader number (input device identification information) and the key ID (personal identification information) inputted into this input device 2 (S1 in FIG. 4). When the continuous authentication is not being performed (S2), the continuous authentication timer 505 starts to count (S3). Thereafter, the control device 5 adds the received key ID to a continuous authentication object ID list (S4).
In contrast, in the step S2, when the continuous authentication is being performed, the control device 5 adds the received key ID to the continuous authentication object ID list (S4).
After that, when the continuous authentication timer 505 completes the count (S11 in FIG. 5), the control device 5 refers to the storage device 4 and selects the door lock device 1 designated as the unlocking object, for each key ID included in the continuous authentication object ID list (S12). The control device 5 determines the key ID related to the unlocking authority having the highest priority with regard to the key IDs included in the continuous authentication object ID list (S13). Thereafter, the control device 5 creates a list (list of the door lock devices 1) indicating the logical sum (union) of the sets of the door lock devices 1 selected for the respective key IDs (S14). The control device 5 compares the present unlocking authority with the previous unlocking authority (S15). When the present unlocking authority has the priority higher than that of the previous unlocking authority or the unlocking authority is not yet set, the control device 5 selects the present unlocking authority as the unlocking authority with regard to the door lock device 1 (S16), and restarts the relocking timer 504 associated with the door lock device 1 designated as the unlocking object (S17). The control device 5 sends the unlocking signal to the door lock device 1 designated as the unlocking object (S18). When the present unlocking authority has the same priority as the previous unlocking authority, the control device 5 restarts the relocking timer 504 associated with the door lock device 1 (S19). When the present unlocking authority has the priority lower than that of the previous unlocking authority, the control device 5 selects zero as the count value of the relocking timer 504 associated with the door lock device 1 not included in the union list out of the door lock devices 1 being unlocked (S20).
When the relocking timer 504 completes the count (S31 in FIG. 6), the control device 5 deletes the unlocking authority related to the door lock device 1 (S32). Subsequently, the control device 5 sends the locking signal to the door lock device 1 which is unlocked (S33). Upon receiving the locking signal, the door lock device 1 locks its electric lock 101.
Next, a usage example of the door lock control system in accordance with the present invention is explained with reference to FIG. 2. In this example, persons working in the building shown in FIG. 2 are classified into an officer, a staff working at the first office 71, a manager working at the first office 71, a staff working at the second office 72, and a manager working at the second office 72. The class information used in the door lock control system includes three of "officer", "manager", and "staff'. The priority of the unlocking authority becomes higher in the order of "staff", "manager", and "officer". Each person has the authentication card 6 storing the personal identification information associated with the locking authority according to a post thereof. For example, the officer has the first authentication card 61, and the manager has the second authentication card 62, and the staff has the third authentication card 63.
First, an explanation is made to a situation where the staff enters the building after the officer enters the building via the main entrance. In this example, the group authentication period is four minutes. In the morning, the officer performs card authentication by the first input device 21. Hence, the personal identification information including the class information indicative of "officer" is inputted into the first input device 21. In this case, the first input device 21 sends the inputted personal identification information ("officer") to the door lock control device 3. Upon receiving the personal identification information "officer" from the first input device 21, the control device 5 (processing unit 503) refers to the correspondence relation stored in the storage device 4, and selects the door lock device 1 associated with the combination of the received personal identification information "officer" and the input device 2 (the input device identification information of the first input device 21) which has sent this personal identification information "officer". In this instance, the control device 5 selects the six door lock devices 11, 13 to 17. The control device 5 controls the six door lock devices 11, 13 to 17 in such a manner to unlock the respective corresponding doors 81, 83 to 87. Therefore, in this instance, according to the correspondence table (see FIG. 3), the first, third to seventh door lock devices 11, 13 to 17 are unlocked. Further, the relocking timers 504 respectively corresponding to the first, third to seventh door lock devices 11, 13 to 17 are activated.
After 3 minutes, the staff comes to the building and performs the card authentication with the first input device 21. At this time, only the first door lock device 11 has been relocked. The control device 5 sends the unlocking signal to only the first door lock device 11. The relocking timers 504 of the respective third, fourth, and seventh door lock devices 13, 14, and 17 are reset and start to count again. Besides, the relocking timers 504 of the respective fifth and sixth door lock devices 15 and 16 continue to count.
The first door lock device 11 is locked again in 1 minute from the time the staff has entered the building. The sixth door lock device 16 is locked again in 1 minute from the time the first door lock device 11 is relocked. The third, fourth, and seventh door lock devices 13, 14 and 17 are locked again in 3 minutes from the time the sixth door lock device 16 is relocked. Subsequently, the fifth door lock device 15 is locked again in 2 minutes (10 minutes from the time the officer has entered the building).
The following explanation relates to the situation where the staff enters the building after the officer enters the building via the main entrance, but the group authentication period is 5 seconds. In the morning, the officer performs the card authentication by the first input device 21. According to the correspondence table (see FIG. 3), the first, third to seventh door lock devices 11, 13 to 17 are unlocked. Further, the relocking timers 504 respectively corresponding to the first, third to seventh door lock devices 11, 13 to 17 are activated. Note that, after the authentication by the officer, the card authentication is not performed before the passage of 5 seconds corresponding to the group authentication period.
After 3 minutes, the staff comes to the building and performs the card authentication with the first input device 21. At this time, only the first door lock device 11 has been relocked.
Upon receiving the identification information (personal identification information) from the first input device 21, the processing unit 503 (control device 5) judges whether or not the predetermined period (10 minutes) passes from a time of receiving the previous identification information (personal identification information) from the same input device 2 (the first input device 21).
In this case, the processing unit 503 concludes that the predetermined period does not pass from the time of receiving the previous identification information (personal identification information) "officer". Hence, the processing unit 503 retrieves the priority of the present identification information (personal identification information "staff") from the storage device 4 and compares the retrieved priority of the present identification information with the priority of the previous identification information (personal identification information "officer").
The priority of the personal identification information "staff" is lower than the priority of the personal identification information "officer". Therefore, the processing unit 503 selects the four door lock devices 11, 13, 14 and 17 associated with the present identification information (personal identification information "staff") with regard to the same input device 2 (in this case, the first input device 21) as the unlocking objects, and controls the door lock devices 11, 13, 14 and 17 selected as the unlocking objects in such a manner to unlock the respective corresponding doors 81, 83, 84, and 87. Besides, with regard to each of the doors 83, 84, and 87, the relocking period does not elapse yet. Hence, with regard to the doors 83, 84, and 87, the count for the relocking period is reset, instead of sending the unlocking signal. Further, the processing unit 503 selects, as the locking objects, the two door lock devices 15 and 16 which are associated with the previous identification information (personal identification information) "officer" but are not associated with the present identification information (personal identification information) "staff" with regard to the same input device 2 (in this case, the first input device 21), and controls the door lock devices 15 and 16 selected as the locking objects in such a manner to lock the respective corresponding doors 85 and 86.
Consequently, since the unlocking authority of the staff has the lower priority relative to that of the officer, the control device 5 sends the unlocking signal to only the first door lock device 11 and sends the locking signals to the respective fifth and sixth door lock devices 15 and 16. The relocking timers 504 of the respective third, fourth, and seventh door lock devices 13, 14, and 17 are reset and start to count again.
The first door lock device 11 is locked again in 1 minute from the time the staff has entered the building. The third, fourth, and seventh door lock devices 13, 14 and 17 are locked again in 4 minutes from the time the first door lock device 11 is relocked.
Next, an explanation is made to a situation where the staff and the officer enter the building via the main entrance simultaneously. The staff and the officer perform the card authentication by the first input device 21 together. First, the staff performs the card authentication. While the control device 5 performs the count by the continuous authentication timer 505, the officer performs the card authentication. After the passage of 5 seconds, in accordance with the unlocking process, the control device 5 sends the unlocking signals to the first, third, and seventh door lock devices 11, 13 to 17 designated as the unlocking objects included in the union of the sets of the staff and the officer.
The door lock control system of the present embodiment as mentioned above includes the plural door lock devices 1, the plural input devices 2, the storage device 4, and the control device 5. The plural door lock devices 1 are provided to the respective different doors, and are configured to allow the respective doors to be in the unlocked-state. The input device 2 is configured to receive the identification information (personal identification information). The storage device 4 is configured to store the correspondence relation between the combination of the identification information and the input device 2 and a set of one or more door lock devices 1 designated as the unlocking objects. The control device 5 is configured to unlock the door lock device 1 designated as the unlocking object which is stored in the storage device 4 in association with the combination of the identification information inputted into the input device 2 and this input device 2, so as to allow the door associated with the door lock device 1 designated as the unlocking object to be in the unlocked-state.
In other words, the door lock control system (lock control system) of the present embodiment includes: the plural door lock devices (lock devices) 1 configured to lock and unlock corresponding doors respectively; the door lock control device (lock control device) 3 configured to control the plural door lock devices 1; and the plural input devices 2 configured to, upon receiving identification information, send the received identification information to the door lock control device 3. The door lock control device 3 includes the storage device 4 and the control device 5. The storage device 4 is configured to store the correspondence relation between the combination of the identification information and the input device 2 (i.e., the input device identification information), that is, the combination of the personal identification information and the input device identification information, and the door lock device 1. The control device 5 is configured to: upon receiving the identification information (personal identification information) from the input device 2, refer to the correspondence relation stored in the storage device 4; and select the door lock device 1 associated with the combination of the received identification information (personal identification information) and the input device 2 which has sent this identification information (personal identification information); and control the selected door lock device 1 in such a manner to unlock the corresponding door. Especially, in the present embodiment, the plural door lock devices 1 are configured to lock and unlock mutually different doors. Further, the plural input devices 2 are located at mutually different sites.
Further, the door lock control device 3 of the present embodiment is defined as a door lock control device which is used together with the plural door lock devices 1 and the plural input devices 2. The plural door lock devices 1 are provided to the respective different doors, and are configured to allow the respective doors to be in the unlocked-state. The input device 2 is configured to receive the identification information (personal identification information). The door lock control device 3 includes the storage device 4 and the control device 5. The storage device 4 is configured to store the correspondence relation between the combination of the identification information and the input device 2 and the set of the one or more door lock devices 1 designated as the unlocking objects. The control device 5 is configured to unlock the door lock device 1 designated as the unlocking object which is stored in the storage device 4 in association with the combination of the identification information inputted into the input device 2 and this input device 2, so as to allow the door associated with the door lock device 1 designated as the unlocking object to be in the unlocked-state.
In other words, the door lock control device (lock control device) is defined as a door lock control device which is connected to the plural door lock devices 1 configured to lock and unlock corresponding doors respectively and the plural input devices 2 configured to receive the identification information (personal identification information). Each of the plural input devices 2 is configured to, upon receiving the identification information (personal identification information), send the received identification information (personal identification information) to the door lock control device 3. The door lock control device 3 includes the storage device 4 and the control device 5. The storage device 4 is configured to store the correspondence relation between the combination of the identification information (personal identification information) and the input device 2 and the door lock device 1. The control device 5 is configured to: upon receiving the identification information (personal identification information) from the input device 2, refer to the correspondence relation stored in the storage device 4; and select the door lock device 1 associated with the combination of the received identification information (personal identification information) and the input device 2 which has sent this identification information (personal identification information); and control the selected door lock device 1 in such a manner to unlock the corresponding door.
According to the door lock control system of the present embodiment as mentioned above, when a user inputs the personal identification information into the input device 2, the plural door lock devices 1 corresponding to the inputted personal identification information are unlocked at one time. Consequently, to reach a desired place, a user is not required to input the personal identification information for each door through which the user intends to pass, yet the improved security of the door lock control system can be maintained.
Additionally, according to the door lock control system of the present embodiment, the door lock device 1 designated as the unlocking object can be selected for each combination of the personal identification information and the input device 2. Hence, for example, with regard to an instance where there are plural routes to a desired place in a building with plural entrances, the door lock control system can unlock the doors in one selected from the routes without unlocking the unnecessary doors in the remaining routes. Therefore, the security can be improved.
Further, in the door lock control system of the present embodiment, the storage device 4 stores the relocking period defining a period between the unlocked time and the relocked time for each of the plural door lock devices 1. The control device 5 selects the relocking period stored in the storage device 4 according to the door lock device 1 designated as the unlocking object. After the passage of the selected relocking period from the time of unlocking the door lock device 1 designated as the unlocking object, the control device 5 locks the door lock device 1 designated as the unlocking object.
In other words, the storage device 4 is configured to store the relocking period for each of the door lock devices 1. The control device 5 is configured to: retrieve the relocking period corresponding to the selected door lock device 1 from the storage device 4; and, after passage of the retrieved relocking period from time at which the selected door lock device 1 has unlocked the corresponding door, control the selected door lock device 1 in such a manner to lock the corresponding door.
Thus, according to the door lock control system of the present embodiment, the relocking periods can be individually selected for the respective corresponding door lock devices 1, and each of the door lock device 1 can be locked after the passage of the corresponding relocking period. For example, to improve the security for a section which a user can reach through a particular door, a short time is selected as the relocking period of the door lock device 1 corresponding to the particular door. Consequently, the security can be improved. Note that, the door lock control system of the present embodiment need not necessarily include this configuration.
The configuration of relocking a designated door after the passage of the predetermined period is employed to achieve two objectives. One of the two objectives is to maintain the security in a building by terminating the unlocked-state of the door lock device 1 after the passage of a prescribed time. The other objective is to improve the convenience by keeping the necessary door lock device 1 in the unlocked-state until a user reaches a desired section or until a user finishes a job at the desired section and leaves the desired section.
Further, in the door lock control system of the present embodiment, the storage device 4 stores the relocking period for each of the plural door lock devices 1 with regard to each piece of the identification information (personal identification information). The control device 5 selects the relocking period stored in the storage device 4 according to the combination of the identification information (personal identification information) inputted into the input device 2 and the door lock device 1 designated as the unlocking object. After the passage of the selected relocking period from the time of unlocking the door lock device 1 designated as the unlocking object, the control device 5 locks the door lock device 1 designated as the unlocking object.
In other words, the storage device 4 is configured to store the relocking period for each combination of the identification information (personal identification information) and the door lock device 1. The control device 5 is configured to: retrieve the relocking period corresponding to the combination of the received identification information (personal identification information) and the selected door lock device 1 from the storage device 4; and, after passage of the retrieved relocking period from time at which the selected door lock device 1 has unlocked the corresponding door, control the selected door lock device 1 in such a manner to lock the corresponding door.
According to the door lock control system of the present embodiment, the time to relocking can be selected for each piece of the personal identification information allocated to users. The aforementioned objectives can be achieved by selecting the relocking period suitable for the user to which the personal identification information is given. Note that, the door lock control system of the present embodiment need not necessarily include this configuration.
Further, in the door lock control system of the present embodiment, the priority is preliminarily allocated to the identification information (personal identification information). When the new identification information (personal identification information) is inputted into the input device 2 after the door lock device 1 designated as the unlocking object is unlocked in response to the input of the identification information (personal identification information) into the input device 2, and when the new identification information has the lower priority than that of the previous identification information, the control device 5 unlocks the door lock device 1 designated as the unlocking object which is stored in the storage device 4 in association with the new identification information, and locks the door lock device 1 which is being unlocked but is not stored in the storage device 4 as the unlocking object in association with the new identification information.
In other words, the storage device 4 is configured to store the priority for each piece of the identification information (personal identification information). The control device 5 is configured to, upon receiving the identification information (personal identification information) from the input device 2, judge whether or not the predetermined period passes from a time of receiving the previous identification information (personal identification information) from the same input device 2. The control device 5 is configured to, upon concluding that the predetermined period does not pass from the time of receiving the previous identification information, retrieve the priority of the present identification information from the storage device 4 and compare the retrieved priority of the present identification information with the priority of the previous identification information. The control device 5 is configured to, upon concluding that the priority of the present identification information is lower than the priority of the previous identification information, select as the unlocking object the door lock device 1 associated with the present identification information with regard to the same input device 2 and control the door lock device 1 selected as the unlocking object in such a manner to unlock the corresponding door, and select as the locking object the door lock device 1 which is associated with the previous identification information but is not associated with the present identification information with regard to the same input device 2 and control the door lock device 1 selected as the locking object in such a manner to lock the corresponding door.
According to the door lock control system of the present embodiment, even when a user having the unlocking authority with the lower priority comes subsequent to a user having the unlocking authority with the higher priority, the user having the unlocking authority with the lower priority can be prevented from entering a section which the user having the unlocking authority with the lower priority is not allowed to enter. Thus, the security can be improved. Note that, the door lock control system of the present embodiment need not necessarily include this configuration.
Further, in the door lock control system of the present embodiment, when plural pieces of the identification information (personal identification information) are inputted into the same input device 2 before a lapse of a predetermined period, the control device 5 selects the door lock device 1 designated as the unlocking object which is stored in the storage device 4 in association with at least one of the plural pieces of the identification information inputted into the input device 2, and unlocks the selected door lock device 1 designated as the unlocking object.
In other words, the control device 5 is configured to judge whether or not an event where plural pieces of the identification information (personal identification information) are inputted into the same input device 2 before passage of a predetermined period has occurred. The control device 5 is configured to, upon concluding that the event has occurred, refer to the correspondence relation stored in the storage device 4 and select the door lock device 1 associated with at least one of the plural pieces of the identification information (personal identification information) with regard to the same input device 2.
As mentioned above, when the plural pieces of the personal identification information are inputted into the same input device 2, the door lock control system of the present embodiment determines the union of sets of the door lock devices 1 designated as the unlocking objects respectively corresponding to the plural pieces of the personal identification information, and thereafter the door lock control system sends the unlocking signal to the door lock device 1 designated as the unlocking object. Therefore, when unlocking ranges of respective plural users overlap with each other,
it is possible to reduce a waste of a communication resource in contrast to an instance where the unlocking signals are sent to all of the door lock devices 1 designated as the unlocking objects for each user. Note that, the door lock control system of the present embodiment need not necessarily include this configuration.
When plural pieces of the personal identification information are inputted into the same input device 2, the door lock control system may determine a product set of plural sets of the door lock devices 1 designated as the unlocking objects instead of the union of sets of the door lock devices 1 designated as the unlocking objects respectively corresponding to the plural pieces of the personal identification information, and thereafter the door lock control system may send the unlocking signal to the door lock device 1 designated as the unlocking object.
In the door lock control system of the present embodiment, when plural pieces of the identification information (personal identification information) are inputted into the same input device 2 within the predetermined period, the control device 5 may select the door lock device 1 designated as the unlocking object which is stored in the storage device 4 in association with all of the plural pieces of the identification information (personal identification information) inputted into the input device 2, and may unlock the selected door lock device 1 designated as the unlocking object.
More specifically, when plural pieces of the personal identification information are inputted into the same input device 2 before a lapse of the predetermined period, the control device 5 selects the door lock device 1 designated as the unlocking object which is stored in the storage device 4 in association with all of the plural pieces of the personal identification information inputted into the input device 2. After selecting the door lock device 1 designated as the unlocking object, the control device 5 sends the unlocking signal to the selected door lock device 1 designated as the unlocking object, for the purpose of unlocking the selected door lock device 1 designated as the unlocking object.
In other words, the control device 5 is configured to judge whether or not an event where plural pieces of the identification information (personal identification information) are inputted into the same input device 2 before passage of a predetermined period has occurred. The control device 5 is configured to, upon concluding that the event has occurred, refer to the correspondence relation stored in the storage device 4 and select the door lock device 1 associated with all of the plural pieces of the identification information (personal identification information) with regard to the same input device 2.
For example, when plural pieces of the identification information (personal identification information) "officer", "manager", and "staff" are inputted into the first input device 21 before a lapse of the predetermined period, the control device 5 selects the four door lock devices 11, 13, 14, and 17 each associated with all of the plural pieces of the identification information (personal identification information) "officer", "manager", and "staff" with regard to the same input device 2 (first input device 21). Consequently, the four doors 81, 83, 84, and 87 respectively corresponding to the four door lock devices 11, 13, 14, and 17 are unlocked.
Note that, the door lock control system of the present embodiment need not necessarily include this configuration.
With regard to the correspondence table stored in the storage device 4, all of the door lock devices 1 may be associated with the same relocking period, and the door lock control device 1 designated as the unlocking object may be associated with each piece of the personal identification information.
In the present embodiment, the storage device 4 may store the relocking period defining a period between the unlocked time and the relocked time for the plural door lock devices 1 with regard to each piece of the identification information (personal identification information). The control device 5 may select the relocking period stored in the storage device 4 according to the identification information (personal identification information) inputted into the input device 2. After the passage of the selected relocking period from the time of unlocking the door lock device 1 designated as the unlocking object, the control device 5 may lock the door lock device 1 designated as the unlocking object.
In other words, the storage device 4 is configured to store the relocking period for each piece of the identification information (personal identification information). The control device 5 is configured to: retrieve the relocking period corresponding to the received identification information (personal identification information) from the storage device 4; and, after passage of the retrieved relocking period from time at which the selected door lock device 1 has unlocked the corresponding door, control the selected door lock device 1 in such a manner to lock the corresponding door.
Note that, the door lock control system of the present embodiment need not necessarily include this configuration.
The continuous authentication timer 505 may be provided to not the control device 5 but each of the input devices 2. In this case, the input device 2 considers plural pieces of the personal identification information received within the group authentication period as the same group and sends them to the control device 5.
As for the door lock control system of the present embodiment, a configuration of measuring the relocking period defining a period between the unlocked time and the relocked time of the door lock device 1 designated as the unlocking object is optional. Further, the configuration of unlocking all of the door lock devices 1 designated as the unlocking objects associated with at least one of the plural pieces of the personal identification information when the plural pieces of the personal identification information are inputted within the predetermined period is optional. In this case, as shown in FIG. 7, the control device 5 of the door lock control device 3 may not include the relocking timer 504 and the continuous authentication timer 505.
In the present embodiment, to allow the control device 5 to identify the input device identification information of the input device 2, the communication unit 501 of the control device 5 is configured to uniquely identify the input device identification information of the input device 2. As for a modification of the present embodiment, a builder may preliminarily give the input device identification information of the input device 2 to the control device 5 by use of a set up device (not shown). In this modification, upon receiving the personal identification information, the input device 2 sends its own input device identification information to the control device 5 together with the personal identification information. In other words, the input device 2 may be configured to, upon receiving the identification information (personal identification information), send the received identification information (personal identification information) and its own input device identification information to the door lock control device 3. In this modification, the control device 5 may be configured to, upon receiving the identification information (personal identification information) and the input device identification information from the input device 2, refer to the correspondence relation stored in the storage device 4 and select the door lock device 1 associated with the combination of the identification information (personal identification information) and the input device identification information which are received, and control the selected door lock device 1 in such a manner to unlock the corresponding door.
The door lock control system may adopt face authentication using a user's face or fingerprint authentication using a user's fingerprint as the authentication means instead of the authentication using the authentication card 6 storing the personal identification information. In this case, not the key ID but a personal ID is used as the personal identification information.
The door lock device 1 is not limited to a configuration employing the electric lock 101, but may be a device designed to open and close a door such as an automatic door. In other words, the door lock device 1 may lock and unlock a door which has no knob and which a user cannot open by hand once it is closed.
In the present embodiment, the explanation is made based on the building of a company. The present embodiment need not necessarily be applied to the building of a company. For example, the present embodiment can be used in an SOHO (Small Office Home Office), a case where a culture class (e.g., a flower arrangement class) is held at one's home, and a case where a friend visits one's home. In such cases, it is possible to obtain the same advantage as the present embodiment.
