Description

The present invention relates to an electric lock device that operates and locks / unlocks an electric lock.

In recent years, the invasion of homes such as vacant nests and robberies and thefts of bicycles and the like have increased, and interest in security is increasing. Such crimes are dealt with by, for example, installing a plurality of keys or introducing a system for unlocking with human body information such as fingerprints.

However, with a mechanical key that locks and unlocks by inserting the key into the keyhole, there is a risk that the key type will be transferred to clay etc. without knowledge, and a key may be created. There was a problem that it was necessary to take action. Also, in the unlocking system based on human body information, there are some people who are resistant to storing fingerprints as data, and when the fingerprints are worn out or injured, they cannot be unlocked. There was a problem.

Conventionally, for example, there is an electric lock control system that unlocks an electric lock installed at an entrance of a door or the like by using a mobile phone in which unlocking data is stored (for example, Patent Document 1). According to the electric lock control system described in Patent Document 1, a password is stored in advance in the mobile phone, and when the user enters the password into the mobile phone, the password is verified and the password matches. A two-dimensional code obtained by encoding the unlocking data is displayed on the display. Then, at the entrance / exit terminal, the unlocked data is read from the two-dimensional code displayed on the display of the mobile phone, and the process of checking the contents of the data stored in advance is performed. A signal is output.

With the electric lock control system described in Patent Document 1, it is not necessary to use a mechanical key or human body information. If the password is not known to a third party, the two-dimensional code is displayed on the display of the mobile phone. The electric lock cannot be unlocked because it cannot be displayed.

However, in the electric lock control system described in Patent Document 1, the mobile phone must determine whether the password stored in advance in the mobile phone matches the password input from the operation unit. Has a problem that a dedicated program or the like must be stored (installed) in advance. Moreover, since there is a possibility that a program must be created for each mobile phone, there is a problem that it is difficult to use such a system. Furthermore, for example, when it is installed at an entrance of a condominium or the like, there is a problem that all users must possess a mobile phone that can use the system. In other words, if there is a user who has a mobile phone that cannot use the system, it is necessary to replace the mobile phone or all users should use this system. There was a problem of having to give up.
In addition, since the password is stored in the mobile phone, there is a problem that the data may be decrypted and the password may be known when it is transferred to a third party.

FIG. 4 is a flowchart showing a subroutine of unlocking data issuing processing performed in the electric lock device. This flowchart is a flowchart showing a process executed after the master device 6 receives a predetermined operation via the input unit 8 and switches to the two-dimensional code issue mode.
First, the CPU 18 receives input of setting ID data (step S10). In this process, a guide for prompting input is displayed on the monitor 9, and input of ID data for setting is accepted. The ID data may be fixedly set for the individual or may be set each time. In addition, when it is set to be fixed to an individual, it is desirable that the unlock data is not issued when ID data that does not correspond to any individual is input.

When receiving input of setting ID data, the CPU 18 issues unlock data in step S11. In this process, the CPU 18 selects and issues one unlocking data from among a plurality of unlocking data stored in the nonvolatile memory 19. At this time, referring to the non-volatile memory 19, one unlock data is selected and issued from the unlock data so as not to select the unlock data issued within the past predetermined period (for example, within one month). To do. Specifically, it is determined whether the unlock data has been issued within the predetermined period in the past depending on whether the unlock data stored in association with the ID data is stored in the nonvolatile memory 19. Select and issue the unlock data. In this process, the CPU 18 functions as issuing means for issuing unlocking data.

Next, in step S12, the CPU 18 stores the input ID data (see step S10) and the issued unlock data (see step S11) in association with each other in the nonvolatile memory 19.

Next, in step S13, the CPU 18 encodes the unlock data into a two-dimensional code. The encoding process will be described in detail later.

In step S14, the CPU 18 displays the encoded two-dimensional code on the monitor 9. In step S15, when an operation to the effect that shooting by the mobile phone 300 is completed is input via the input unit 8, the display of the two-dimensional code is terminated, and the two-dimensional code issue mode is switched to the normal mode. This subroutine is finished.

FIG. 5 is a flowchart showing an encoding process subroutine called and executed in step S13 of the subroutine shown in FIG.

First, the CPU 18 sets unlocking data as an encoding process target (step S40).

Next, the CPU 18 creates a mode identifier corresponding to the character type (for example, numbers, alphanumeric characters, kanji, etc.) of the unlock data (step S41).
Next, the CPU 18 creates a character number identifier corresponding to the number of characters in the unlock data (step S42).
Next, the CPU 18 performs a process of binarizing the unlock data (step S43).
Next, the CPU 18 performs processing for adding a termination pattern to the data obtained in steps S41 to S43 (step S44).

Next, the CPU 18 performs code word conversion of the data obtained in step S44 (step S45), and further creates an error correction code word based on the data obtained in step S45, and is obtained in step S45. It is added to the data (step S46). Next, the CPU 18 performs a process of binarizing the data obtained in step S46 and arranging the data in a matrix (step S47).
Next, the CPU 18 performs a process of masking a predetermined pattern on the data obtained in step S47 (step S48). Next, a process for adding format information including an error correction level and a mask identifier is performed (step S49), and a two-dimensional code is generated (step S50). Thereafter, this subroutine is terminated.

In the present embodiment, the case where only unlocked data is encoded (encoded) into a two-dimensional code has been described. However, in the present invention, unlocked data and other data (for example, the time when unlocked data is issued) Data etc.) may be encoded.

FIG. 6 is a flowchart showing a subroutine of unlocking processing performed in the electric lock device. This flowchart is a flowchart showing processing executed after the operation of the changeover switch 4 is accepted in the slave unit 1 and the CCD camera 2 is switched to optical characteristics (close-up mode) suitable for photographing a two-dimensional code.
First, when receiving an ON signal from the changeover switch 4, the CPU 18 performs an operation of setting a standby time timer (step 60). The waiting time timer is timed up in 1 minute, for example.

Next, the CPU 18 determines whether or not the waiting time timer has expired (step S61), and if it is determined that the time has expired, the optical characteristic switching unit 29 is returned to the CCD camera 2 to return. The optical characteristics (normal mode) suitable for the user's photographing are switched (step S71), and this subroutine is finished. On the other hand, if it is determined that the time is not up, the process proceeds to step S62.

In step S62, the CPU 18 determines whether or not collation ID data has been input via the input unit 33 (step S62). If it is determined that ID data has been input, the process proceeds to step S63. On the other hand, if there is no input of ID data, the process returns to step S61.

In step S <b> 63, the CPU 18 reads unlocking data corresponding to the input ID data (see step S <b> 62) from the nonvolatile memory 19. This unlocking data is data stored in association with the ID data when issued in the unlocking data issuing process (see step S12 in FIG. 4).

Next, the screen image displayed on the liquid crystal panel 306 of the mobile phone 300 by the operation via the operation unit 306 is taken by the CCD camera 2 (step S64), and the image data is stored (step S65).

Next, the CPU 18 performs a two-dimensional code recognition process (step S66), reads the two-dimensional code from the image data obtained in step S65, and generates unlocking data. In this process, the CPU 18 functions as a reading unit that reads the two-dimensional code 92. The two-dimensional code recognition process will be described in detail later.

Next, the CPU 18 determines whether or not the recognition of the two-dimensional code is successful (step S67). If it is determined that the two-dimensional code has not been successfully recognized, the process returns to step S61. On the other hand, if it is determined that the two-dimensional code has been successfully recognized, the process proceeds to step S68.

In step S68, the CPU 18 determines whether or not the read unlock data (see step S63) matches the generated unlock data (see step S66). If it is determined that they do not match, the process returns to step S61. If it is determined that they match, the process proceeds to step S69. In this process, the CPU 18 functions as a determination unit that determines whether unlock data corresponding to the ID data input by the input unit 33 has been generated.

In step S <b> 69, the CPU 18 outputs an unlock signal to the electric lock 5. At this time, the CPU 18 functions as an unlocking unit that performs an operation of unlocking the electric lock 5. Thereby, the electromagnetic solenoid 31 is driven, and the lock of the electric lock 5 is unlocked.
Next, in step S70, the unlocking data used for unlocking is invalidated. In this process, the CPU 18 invalidates the unlock data by setting a flag indicating that the unlock data has been used in a predetermined area of the nonvolatile memory 19. As a result, the unlocked data in which the flag is set is not read as unlocked data corresponding to the ID data, and even if the same unlocked data is used twice, The lock cannot be unlocked.
Next, in step S71, the CCD camera 2 is switched to optical characteristics (normal mode) suitable for shooting by the visitor, and this subroutine is terminated.

FIG. 7 is a flowchart showing the two-dimensional code recognition process called and executed in step S66 of the process shown in FIG.
First, the CPU 18 performs an image conversion process on the image data stored in the nonvolatile memory 19 (step S80). The image conversion process extracts the image data of the area where the two-dimensional code is displayed from the image data obtained by imaging, corrects the inclination and distortion, converts the image data to a monochrome image with a predetermined threshold, and views it from the front This is processing for obtaining image data including a two-dimensional code.

Next, the CPU 18 extracts a two-dimensional code from the image data obtained in step S80 and performs correction such as noise removal (step S81).
Next, the CPU 18 binarizes the two-dimensional code obtained in step S81, and replaces each dot constituting the two-dimensional code with “0” or “1” (step S82). Data is generated (step S83). Next, the CPU 18 decodes the binarized matrix data (step S84) and generates unlocking data (step S85). Thereafter, this subroutine is terminated, and the process proceeds to step S67 of the flowchart shown in FIG.

As described above, according to the electric lock device 10 according to the present embodiment, the unlocking data generated by reading the two-dimensional code 92 encoded with the unlocking data for unlocking the electric lock 5 from the liquid crystal panel 306 of the mobile phone 300 is generated. When it is determined that the lock data is unlock data corresponding to the ID data input by the input unit 33 (collation ID data input means), an operation of unlocking the electric lock 5 is performed. That is, even when the two-dimensional code 92 is read and unlock data is generated, if the unlock data does not correspond to the ID data input by the input unit 33, the unlock operation is not performed. Accordingly, even when the two-dimensional code 92 is obtained by a third party by copying or the like, it is necessary to input the ID data in order to unlock the electric lock 5, so that it is unlocked.

As described above, when the ID data is input by the input unit 8, the two-dimensional code 92 is displayed. Therefore, the user can acquire a new two-dimensional code 92 at any time. Therefore, higher security can be obtained.

In addition, according to the electric lock device 10 according to the present embodiment, since different unlock data is issued every time ID data is input by the input unit 8, the unlock data encoded each time is different. Become. Thus, since the correspondence between the ID data and the unlocking data is changed each time, even if the two-dimensional code 92 is copied, the possibility of being unlocked by the two-dimensional code 92 is reduced. High security can be obtained.
