The lock is released by energizing the solenoid 67 based on a predetermined condition.
[0025]
Next, the operation of the fingerprint lock device will be described. FIG. 7 is a block diagram showing a functional configuration of the fingerprint lock device.
[0026]
As shown in the figure, the fingerprint lock device includes an operation unit 101, an operation unit 102, an operation processing unit 103, a fingerprint sensor 104, a sensor mounting unit 105, a sensor attachment / detachment control unit 106, a collation / control processing unit 107, and a display control unit. 108, a display unit 109, a display unit 110, a storage unit 111, a lock control unit 112, and an electric lock 113.
[0027]
The operation unit 101 and the operation unit 102 are each configured by a switch such as a button, and are used to input an operation instruction from the operator. The operation unit 101 is disposed in the inner unit 20 disposed inside the door, and the operation unit 102 is disposed in the outer unit 10 disposed outside the door. The operation unit 102 corresponds to the operation unit 12 shown in FIG.
[0028]
The operation processing unit 103 is a part that receives and processes operation instructions input from the operation unit 101 and the operation unit 102 and is disposed in the inner unit 20.
[0029]
The fingerprint sensor 104 is a sensor that acquires a fingerprint image, and corresponds to the above-described fingerprint sensor 50.
[0030]
The sensor mounting part 105 is a part where the fingerprint sensor 104 is mounted, and corresponds to the mounting part 60 described above.
[0031]
The sensor attachment / detachment control unit 106 controls the attachment / detachment of the fingerprint sensor 104 attached to the sensor attachment unit 105, and controls the energization to the solenoid 67 described above, thereby releasing the lock.
[0032]
The collation / control processing unit 107 extracts a feature amount from the fingerprint image acquired by the fingerprint sensor 104, collates the feature amount with the fingerprint image stored in the storage unit 111 or the feature amount thereof, and This is the part that controls. The collation / control processing unit 107 is disposed in the inner unit 20.
[0033]
The display control unit 108 displays an instruction to the operator or the like on the display unit 109 or the display unit 110 and is disposed in the inner unit 20.
[0034]
The display unit 109 is disposed in the inner unit 20 and includes an indicator (LED or the like) or a display for displaying an instruction to the operator.
[0035]
The display unit 110 is disposed in the outer unit 10 and includes an indicator (LED or the like) or a display for displaying an instruction to the operator. The display unit 110 corresponds to the display unit 13 shown in FIG.
[0036]
The storage unit 111 stores a pre-registered fingerprint (a fingerprint of a person authorized to unlock) as an image or a feature amount thereof, and is disposed in the inner unit 20.
[0037]

[0038]
The electric lock 113 is a lock that locks and unlocks the door, and corresponds to the electric lock 21 described above.
[0039]
FIG. 8 is a flowchart showing the operation flow of the fingerprint lock device. When an operation instruction is input from the operation unit 101 or the operation unit 102, the fingerprint lock device is turned on and first performs initialization processing of each unit (step 200). When the initialization process is completed, if there is an operation instruction other than unlocking from the operation unit 101 or the operation unit 102 (YES in step 201), the corresponding process is performed (step 202). Operations other than unlocking will be described later.
[0040]
On the other hand, if there is no operation other than unlocking (NO in step 201) and a finger is placed on fingerprint sensor 104 (finger placing unit 51 of fingerprint sensor 50) (YES in step 203), the collation / control processing unit 107 operates the fingerprint sensor 104 to acquire a fingerprint image of the placed finger (step 204), and compares the acquired fingerprint image with the fingerprint image registered in the storage unit 111 or its feature amount (step 205). .
[0041]
If the acquired fingerprint image matches the registered one as a result of the fingerprint image collation (YES in step 206), the lock control unit 112 operates the electric lock 113 to unlock (step 207). Then, when a predetermined time, for example, 5 seconds elapses after unlocking (YES in step 208), the lock control unit 112 operates the electric lock 113 to perform locking (step 209), and the process is terminated. Further, when locking is performed after a certain period of time, it may be confirmed that the door is closed.
[0042]
On the other hand, if the acquired fingerprint image does not match the registered one as a result of the fingerprint image collation (NO in step 206), the processing is terminated as it is.
[0043]
Next, processing other than unlocking processed in step 202 will be described. Processing other than unlocking includes processing similar to that of a conventional fingerprint locking device such as fingerprint registration and deletion, and removal processing of the fingerprint sensor 104 (fingerprint sensor 50). Here, the description of the process similar to the conventional process is omitted, and only the removal process of the fingerprint sensor 104 will be described.
[0044]
The fingerprint sensor removal process is different depending on an operation instruction from the operation unit 101 and an operation instruction from the operation unit 102. When an operation instruction for removing the fingerprint sensor 104 is given from the operation unit 101, the operator is present inside the door, and therefore the sensor attachment / detachment control unit 106 is immediately responded to the operation instruction from the operation unit 101. Unlocks the sensor 104.
[0045]
On the other hand, when an operation instruction for removing the fingerprint sensor 104 is given from the operation unit 102, the operator is present outside the door. Therefore, the operator is authenticated for the operation instruction from the operation unit 102. FIG. 9 is a flowchart showing a processing flow when an instruction to remove the fingerprint sensor 104 is issued from the operation unit 102.
[0046]
When there is an instruction to remove the fingerprint sensor 104 from the operation unit 102, first, it waits for the operator's finger to be placed on the fingerprint sensor 104 (NO in step 220). When the operator's finger is placed (YES in step 220), the collation / control processing unit 107 operates the fingerprint sensor 104 to obtain a fingerprint image of the placed finger (step 221), and the obtained fingerprint The image is collated with the fingerprint image registered in the storage unit 111 or its feature amount (step 222).
[0047]
As a result of the fingerprint image collation, if the acquired fingerprint image matches the registered one (YES in step 223), the sensor attachment / detachment control unit 106 energizes the solenoid 67 and unlocks the fingerprint sensor 104 (step 224).
[0048]
On the other hand, if the acquired fingerprint image does not match the registered one as a result of the fingerprint image collation (NO in step 223), the processing is terminated as it is.
[0049]
By the way, in the above description, the fingerprint sensor 104 has been removed according to an operator's instruction. However, if the fingerprint sensor 104 is not removed for a long time, the fingerprint sensor 104 may become dirty or malfunction. For this reason, it is convenient that the fingerprint sensor 104 can be removed and replaced with another fingerprint sensor 104 even when a malfunction such as a failure occurs in the fingerprint sensor 104. In view of this, a process for removing the fingerprint sensor 104 when a problem occurs in the fingerprint sensor 104 will be described below. FIG. 10 is a flowchart showing a processing flow of the fingerprint lock device when the fingerprint sensor 104 is removed when a failure occurs in the fingerprint sensor 104.
[0050]
When an operation instruction is input from the operation unit 101 or the operation unit 102, the fingerprint lock device is turned on and first performs initialization processing of each unit (step 300). When the initialization process ends, if there is an operation instruction other than unlocking from the operation unit 101 or the operation unit 102 (YES in step 301), the corresponding process is performed (step 302). The operations other than unlocking are the same as those described above.
[0051]
On the other hand, if there is no operation other than unlocking (NO in step 301) and a finger is placed on fingerprint sensor 104 (finger placing unit 51 of fingerprint sensor 50) (YES in step 303), the collation / control processing unit 107 obtains a fingerprint image of the placed finger by operating the fingerprint sensor 104 (step 304), and determines whether the fingerprint sensor 104 is soiled or malfunctioned based on the obtained fingerprint image (step 305). ). Since this determination is performed by a conventional technique similar to “Fingerprint collation system failure detection method and apparatus” described in Japanese Patent Application Laid-Open No. 2001-52179, description thereof is omitted here.
[0052]
As a result of the determination, if there is no malfunction in the fingerprint sensor 104 (NO in step 306), the previously acquired fingerprint image is collated with the fingerprint image registered in the storage unit 111 or its feature amount (step 307).
[0053]
If the acquired fingerprint image matches the registered one as a result of the fingerprint image collation (YES in step 308), the lock control unit 112 operates the electric lock 113 to unlock (step 309). When a predetermined time, for example, 5 seconds elapses after unlocking (YES in step 310), the lock control unit 112 operates the electric lock 113 to perform locking (step 311), and the process ends. If the acquired fingerprint image does not match the registered image as a result of the fingerprint image collation (NO in step 310), the processing is terminated as it is. Further, when the door is unlocked once and locked after a certain period of time, it may be confirmed that the door is closed.
[0054]
On the other hand, if the fingerprint sensor 104 has a defect as a result of the presence or absence of contamination or the occurrence of a failure (YES in step 306), the sensor attachment / detachment control unit 106 energizes the solenoid 67 to The lock is released (step 312), and the process ends.
[0055]
