In addition, about the structure of the electric lock control apparatus 1 concerning this Embodiment, it is the same as that of 1st Embodiment (refer FIG. 1), and description here is abbreviate | omitted.

[Operation of Second Embodiment]
Next, the operation of the electric lock control device 1 according to the second embodiment of the present invention will be described with reference to FIGS. 4 and 5. FIG. 4 is a flowchart showing a lock control process of the electric lock control device according to the second embodiment of the present invention. The same reference numerals are given to the same or equivalent parts as in FIG. FIG. 5 is a sequence diagram showing an example of the lock control operation of the electric lock control device according to the second embodiment of the present invention. The same reference numerals are given to the same or equivalent parts as those in FIG.

With reference to FIG. 4, the lock control process of the electric lock control apparatus concerning the 2nd Embodiment of this invention is demonstrated.
The lock control unit 17 of the electric lock control device 1 always executes the lock control process of FIG. In addition, the setting contents of the locking / unlocking state at the time of power failure and the locking / unlocking state during energization set by the locking / unlocking state setting unit 15 are pre-stored in the storage unit 16 by the lock control unit 17 as the locking / unlocking state information 16A. And In addition, it is assumed that the lock operation request from the lock operation terminal 2 includes a command level corresponding to the security level of the user.

When the occurrence of a power failure is detected by the power failure detection unit 14 in the standby state (step 100: occurrence of a power failure), the lock control unit 17 accepts the lock operation request for the command processing for the lock operation request from the lock operation terminal 2. No command restriction is set (step 200). This command restriction state may be held in the lock control unit 17 or may be stored in the storage unit 16.
Subsequently, the lock control unit 17 refers to the lock / unlock state information 16A of the storage unit 16 to acquire the lock / unlock state at the time of power failure (step 101), and to control the electric lock 3 to the lock / unlock state at the time of power failure. Is transmitted from the electric lock I / F unit 12 to the electric lock 3 via the communication line 53 (step 102), and the process returns to step 100. At the time of a power failure, the electric lock control device 1 and the electric lock 3 operate based on the operation power supplied from the power supply unit 13.

In the standby state, when the power failure detection unit 14 detects the restart of power supply (recovery) (step 100: restart of power supply), the lock control unit 17 performs command processing for the lock operation request from the lock operation terminal 2. The restriction is released to the state of no command restriction for accepting the lock operation request (step 201).
Subsequently, the lock control unit 17 refers to the lock / unlock state information 16A in the storage unit 16 to acquire the energized lock / unlock state (step 103), and controls the electric lock 3 to the energized lock / unlock state. Is transmitted from the electric lock I / F unit 12 to the electric lock 3 via the communication line 53 (step 104), and the process returns to step 100.

  In the standby state, when the lock operation request is received from the lock operation terminal 2 by the communication I / F unit 11 (step 100: there is a lock operation request), the lock control unit 17 checks the command restriction state ( In step 202), when there is a command restriction (step 202: YES), the command level of the lock operation request from the lock operation terminal 2 is checked to determine whether or not it can be executed (step 203).

If the command level of the lock operation request is below the reference level, it is determined that the lock operation request cannot be executed (step 204: NO), and the process returns to step 100. On the other hand, when the command level of the lock operation request is equal to or higher than the reference level, it is determined that the lock operation request can be executed (step 204: YES), and the electric lock 3 is brought into the locked / unlocked state corresponding to the lock operation request. A control command to be controlled is transmitted from the electric lock I / F unit 12 to the electric lock 3 via the communication line 53 (step 105), and the process returns to step 100.
If there is no command restriction in step 202 (step 202: NO), the process proceeds to step 105 without performing the command restriction determination.

  When the electric lock 3 receives the unlock command from the electric lock control device 1 in response to the occurrence of the power failure, the electric lock 3 puts the door in the unlocked state (step 215). As a result, in the event of a power failure, regardless of the type of operation of the electric lock 3, the entrance / exit door of the management target area is controlled to the unlocked state, and the command restriction state is set so that the lock operation request from the lock operation terminal 2 is not accepted. Is done.

When the user performs a locking operation on the management target area with the lock operation terminal 2 during a power failure (step 220), the lock operation terminal 2 locks the electric lock control device 1 via the communication line 52 accordingly. A request is sent (step 221).
The lock control unit 17 of the electric lock control device 1 confirms that the command is restricted by the lock control process (see FIG. 4) of the lock control unit 17 described above (step 222), and the communication I / F unit 11 checks the command level included in the lock request received from the lock operation terminal 2 (step 223). Here, since the command level included in the locking request is below the reference level, it is determined that the locking request cannot be executed (step 224). Thereby, the control command corresponding to the locking request is not transmitted to the electric lock 3.

In the event of a power failure, when the supply of commercial power is restored and energization is resumed, the power supply unit 13 of the electric lock control device 1 switches to supply the operation power from the commercial power (step 230).
Further, in response to the detection of the resumption of energization by the power failure detection unit 14 (step 231), the lock control unit 17 releases the restriction to the state without the command restriction for accepting the lock operation request from the lock operation terminal 2 (step 232). ), “Locking” is acquired as the locking / unlocking state at the time of energization from the locking / unlocking state information 16 A of the storage unit 16 (step 233), and a locking command for locking the electric lock 3 is communicated from the electric lock I / F unit 12. Transmission is made to the electric lock 3 via the line 53 (step 234).

  When the electric lock 3 receives the lock command from the electric lock control device 1 in response to the resumption of energization, the electric lock 3 puts the door in the locked state (step 235). Thereby, at the time of energization, the entrance door of the management target area is controlled to be locked regardless of the operation type of the electric lock 3, and is set to a state without command restriction for receiving a lock operation request from the lock operation terminal 2. .

  As described above, in the present embodiment, when the occurrence of a power failure is detected by the power failure detection unit 14, the transmission of the control command according to the instruction from the lock operation terminal 2 is limited. Access to the target area can be managed in a desired state.

  Therefore, if the unlocking state at the time of power failure is set to “unlocked”, the lock request from the lock operation terminal 2 by the general user at the time of power failure is canceled, so the doorway to the management target area is unlocked at the time of power failure It can be maintained in a state, and smooth operability can be obtained in the event of a power outage and the safety of residents can be ensured. On the other hand, if the unlocking state at the time of power failure is set to “locked”, the unlocking request from the lock operation terminal 2 by the general user at the time of power failure is canceled, so the entrance door to the management target area is locked at the time of power failure It is possible to maintain high security in the event of a power failure.

And In addition, it is assumed that the lock operation request from the lock operation terminal 2 includes a command level corresponding to the security level of the user.

  In the standby state, the lock control unit 17 confirms the command restriction state when the communication I / F unit 11 receives a lock operation request from the lock operation terminal 2 (step 100: there is a lock operation request) (step 202). If there is a command restriction (step 202: YES), the command level of the lock operation request from the lock operation terminal 2 is inspected to determine whether it can be executed (step 203).

  Here, when the command level of the lock operation request is lower than the reference level, it is determined that the lock operation request cannot be executed (step 204: NO), and only when there is a power failure at present (step 303: YES). Then, the contents of the lock operation request are saved in the storage unit 16 as a save command (step 304), and the process returns to step 100.

On the other hand, when the command level of the lock operation request is equal to or higher than the reference level, it is determined that the lock operation request can be executed (step 204: YES), and the electric lock 3 is brought into the locked / unlocked state corresponding to the lock operation request. A control command to be controlled is transmitted from the electric lock I / F unit 12 to the electric lock 3 via the communication line 53 (step 105), and the process returns to step 100.
If there is no command restriction in step 202 (step 202: NO), the process proceeds to step 105 without performing the command restriction determination.

  In the standby state, when the power failure detection unit 14 detects the restart of power supply (recovery) (step 100: restart of power supply), the lock control unit 17 performs command processing for the lock operation request from the lock operation terminal 2. The restriction is released to the state of no command restriction for accepting the lock operation request (step 201), and the lock / unlock state at energization is acquired with reference to the lock / unlock state information 16A of the storage unit 16 (step 103).

Here, when the storage command is stored in the storage unit 16 (step 300: YES), the lock control unit 17 reads the storage command from the storage unit 16, analyzes the content, and updates the locked / unlocked state when energized. (Step 301), the stored command in the storage unit 16 is deleted (step 302). At this time, the lock control unit 17 reads the saved commands in the order of reception (in time order), updates the energization / unlocking state at the time of energization in order according to the contents, and finally the electric lock at the current present, that is, at the time of resuming energization. The energization locking / unlocking state is updated to 3 locking / unlocking state.
Thereafter, the lock control unit 17 transmits a control command for controlling the electric lock 3 to the unlocked / unlocked state when energized from the electric lock I / F unit 12 to the electric lock 3 via the communication line 53 (step 104). Return to Step 100.

  If the command level of the electric lock control device 1 itself can be set in multiple stages as well as whether the command is restricted or not, the device command level when energized is compared with the command level of each saved command. Thus, the execution / non-execution of the storage command may be checked, and the energization locking / unlocking state may be updated based only on the storage command determined to be executable. As a result, the key control process corresponding to the command level can be realized for the lock operation request received at the time of a power failure as in the case of energization, and high security can be obtained.

  Next, an example of a lock control operation of the electric lock control device according to the third embodiment of the present invention will be described with reference to FIG. Here, in the unlocking state information 16A of the storage unit 16, “unlocked” is set as the unlocked state at the time of power failure of the electric lock 3 and “unlocked” is set as the unlocked state during energization. It shall be. Further, it is assumed that, when energized, a power failure occurs due to the stop of the supply of commercial power, and steps 210 to 215 in FIG. 5 described above are executed, and the electric lock 3 is unlocked.

When the user performs a locking operation on the management target area with the lock operation terminal 2 during a power failure (step 220), the lock operation terminal 2 locks the electric lock control device 1 via the communication line 52 accordingly. A request is sent (step 221).
The lock control unit 17 of the electric lock control device 1 confirms that the command is restricted by the lock control process (see FIG. 4) of the lock control unit 17 described above (step 222), and the communication I / F unit 11 checks the command level included in the lock request received from the lock operation terminal 2 (step 223).

  Here, since the command level included in the locking request is lower than the reference level, it is determined that the locking request cannot be executed (step 224), and the locking request is stored in the storage unit 16 as a storage command (step 320). Thereby, the control command corresponding to the locking request is not transmitted to the electric lock 3.

In the event of a power failure, when the supply of commercial power is restored and energization is resumed, the power supply unit 13 of the electric lock control device 1 switches to supply the operation power from the commercial power (step 230).
Further, in response to the detection of the resumption of energization by the power failure detection unit 14 (step 231), the lock control unit 17 releases the restriction to the state without the command restriction for accepting the lock operation request from the lock operation terminal 2 (step 232). ), “Unlocked” is acquired as the locking / unlocking state at the time of energization from the locking / unlocking state information 16A of the storage unit 16 (step 233).

Here, since the save command is saved in the storage unit 16, the energization locking / unlocking state is updated based on the save command (step 330), and the save command in the storage unit 16 is deleted (step 331). As a result, the unlocked state when energized is recognized as “unlocked” in step 233, and then updated to “locked” by the save command in step 320.
Thereafter, a locking command for locking the electric lock 3 is transmitted from the electric lock I / F unit 12 to the electric lock 3 via the communication line 53 (step 234).

  When the electric lock 3 receives the lock command from the electric lock control device 1 in response to the resumption of energization, the electric lock 3 puts the door in the locked state (step 235). Thereby, at the time of energization, the entrance door of the management target area is controlled to be locked regardless of the operation type of the electric lock 3, and is set to a state without command restriction for receiving a lock operation request from the lock operation terminal 2. .

  As described above, in this embodiment, the lock operation request received in a state where the command is restricted due to a power failure is saved as a save command, and when the energization is resumed, the saved command is analyzed to update the energization / unlock state. Therefore, the lock operation request received at the time of a power failure can be reflected as the locked / unlocked state of the electric lock 3 when energization is resumed. Thereby, for example, even when there is a lock operation request from a host device (not shown) based on the key control schedule at the time of power failure, the electric lock 3 is controlled to the locked / unlocked state corresponding to the lock operation request when energization is resumed. And the key control schedule can be continued.

[Extended embodiment]
In each of the above-described embodiments, the case where either “locking” or “unlocking” is set as an example of the unlocking state at the time of a power failure with respect to the electric lock 3 has been described, but the present invention is not limited thereto. For example, it may be possible to set “maintain current” for maintaining the locked / unlocked state during energization even during a power failure. When this “maintain status” is set, the locked state during energization may be used as the unlocked state during power failure in the lock control process.

  In each embodiment, the case where either “locked” or “unlocked” is set as the locked state during energization and the electric lock 3 is controlled to the locked state during energization when energization is resumed has been described. The locked state when energized is not limited to a fixed locked / unlocked state such as “locked” or “unlocked”. For example, if “locking state immediately before power failure detection” is set as the locked state upon energization, the unlocking state immediately before power failure of the electric lock 3 is stored when a power failure is detected, and the power is restored based on the stored contents when power is resumed. The lock may be controlled to the unlocked / unlocked state immediately before the power failure, and more flexible lock control can be realized.

  Moreover, it is good also as a more detailed setting as an unlocking state at the time of a power failure. For example, when the security state is acquired from the lock operation terminal 2 or the host device (not shown) via the communication I / F unit 11 and the security state indicates “non-warning”, “unlock” is set. When “warning” is indicated, “locking” may be used. Alternatively, it may be “unlocked” when the passage mode of the doorway is “limit” (when traffic is permitted), and “locked” when it is “closed” (when traffic is restricted). In addition, “unlock” may be used when the power outage time is a working hour, and “locked” may be used when the time is other than this. Further, if the number of people in the management target area is equal to or greater than the reference number, “unlock” may be used, and if the number is less than the reference number, “locked” may be set.
