Description

  The present invention relates to an electric lock device that is unlocked by inputting a personal identification number, and more particularly to an electric lock device provided on a door such as a door.

The electric lock device is configured such that a multi-digit number or symbol is input by operating an operation unit equipped with a numeric keypad, and the door is unlocked when the input number matches a preset number sequence. ing. By using such an electric lock, the user does not need to carry a lock for unlocking, and the situation where the lock is lost can be prevented. In addition, the key can be easily changed, and the password can be changed by operating a predetermined button on the operation unit. Even when the password is leaked, it can be easily dealt with.
For example, in Patent Document 1, an input setting unit having a numeric keypad is provided on a door incorporating an electric lock, and unlocking is enabled by inputting a predetermined unlocking code number using the numeric keypad. The security code setting mode is entered by inserting it into the hole, and the unlock code can be changed by operating the numeric keypad and entering the number in this state.

Japanese Patent Laid-Open No. 9-264086

However, since the unlocking code number is set and changed in the instruction manual of the electric lock, the unlocking code number can be changed by a user other than the administrator, or it can be unlocked by a third party. There was a risk that the lock code number could be decrypted or newly set and unlocked.
Therefore, in order to prevent such tampering or decryption of the personal identification number, a configuration in which the electric lock unlocking device itself is stored in a separate box that can be locked is conceivable. Since it is difficult to grasp the state, it is not a preferable configuration for security.

  Therefore, in view of such problems, the present invention has an object to provide an electric lock device in which it is difficult to decode or change the unlock code number.

In order to solve the above-mentioned problems, the invention of claim 1 is characterized in that at least one electric lock, an external operation unit for performing an unlocking operation with a numeric keypad, etc., and an unlock code number are input from the external operation unit.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments of the invention will be described in detail with reference to the drawings. FIG. 1 is a configuration diagram of an electric lock device according to the present invention, and an electric lock 1 incorporated in a door and an electric lock control device that is installed in a room partitioned by the door and controls the unlocking / locking of the electric lock 1. 2, and an external operation unit 3 that is installed on the outside of the door itself or on the wall surface near the door that is outside the room, and the like, for operating the unlocking of the electric lock 1. The electric lock 1 is connected to the electric lock control device 2 via the transmission line L1, and the external operation unit 3 is connected to the electric lock control device 2 via the transmission line L2.

FIG. 2 shows a block diagram of the electric lock control device 2. As shown in FIG. 2, the electric lock control device 2 includes an electric lock driving unit 10 that drives the electric lock 1, an electric lock interface (electric lock IF) 11 for obtaining a lock / unlock status signal from the electric lock 1, To display the main body operation unit 12 having a numeric keypad for various settings of the electric lock device, the buzzer 13 and buzzer drive unit 14 for notifying the completion of the setting, and the lock / unlock state and the set state of the electric lock 1 A display unit 15 comprising an LCD, a number storage unit 16 for storing an unlocking code number and a set code number, an external operation unit interface (external operation unit IF) 17 for communicating with the external operation unit 3, and the entire electric lock control device CPU section 18 for controlling the power supply, power supply section 20 for supplying power to each section, and the like.
The unlock code number is a code number for unlocking the electric lock 1, and the set code number is a code number that needs to be input when setting or changing the unlock code number.

  The operation of the electric lock control device configured as described above is as follows. However, when the unlocking code number is input from the external operation unit 3, the operation of unlocking the electric lock 1 is the same as the conventional one, so the description is omitted. Here, the unlocking code number is set (and changed, deleted, confirmed). ) And the flow of setting (and changing, erasing, and confirming) the set password are described.

  First, setting (and changing, deleting, confirming) the unlock code number will be described based on the flow of FIG. However, the main body operation unit 12 is provided with a numeric keypad composed of numeric buttons “0” to “9” and symbol buttons such as a “*” button and a “#” button. In addition to numbers 0 to 9, symbols (hereinafter collectively referred to as “numbers”) are used. In addition, three types of unlock code numbers can be set for one electric lock 1, and the set code number is fixed to 4 digits.

  First, after depressing the “*” key, any one of numbers 1 to 3 is continuously input. The “*” key is a symbol for shifting to the setting mode, and the next “n” key is a number that designates the number of the three types of unlocking code numbers. Further, the “set password” and “unlocked password to be used” are input, and finally the end key “#” is input to set the unlocked password.

  Specifically, “3232” is stored in the number storage unit 16 as the first set personal identification number and “12345” is set as the unlock personal identification number as follows. The main body operation unit 12 is operated to input “* 1323212345 #” based on the above conditions. In response to this input, if the most significant digit is “*”, the CPU 18 determines that it is an operation for setting (and changing or deleting) the unlock code (S1), and enters the setting mode. Next, it is determined that the first unlock code number among the three types is set by inputting "1" in the second digit (S2).

Subsequently, it is determined whether the third to sixth digits arranged after “* 1” are set passwords (S3). The CPU unit 18 compares the number stored in the number storage unit 16 with the number “3232” input from the main body operation unit 12. Here, it is determined that it is the set password, and the process proceeds to the next to determine whether “#” is in the digit (S5).
However, if the set password is different from the number stored in the number storage unit 16, an error is displayed on the display unit 15 (S4), and the buzzer 13 is sounded to set the unlock code number setting mode. End. In this case, the unlock code number stored in the current number storage unit 16 is maintained.

Then, it is determined whether or not the detected “#” is the seventh digit (S7). Since there is no seventh digit here, it is determined that the unlocking code number is from the seventh digit to the last digit (S9). The lock code number is set and registered. At the time of registration, the display unit 15 displays that the unlock code has been set, and the setting mode ends (S10).
However, if there is no “#” in the last digit, an error is displayed (S6), the buzzer 13 is sounded, and the setting mode ends. If necessary, an operator such as an administrator resets the settings.

  The operation for changing the unlocking code number is the same as the setting operation described above, and the old unlocking code number is overwritten with the new unlocking code number and the number is updated by the setting operation.

  The unlock code is erased as follows. “* 13232 #” is input in the first input operation. By inputting only the set personal identification number, the CPU 18 determines that the first unlocking personal identification number is “0000” because “#” is the seventh digit in the judgment step (S7) of the seventh digit. Then, control is performed to change the unlock code number to “0000”. In this way, erasure is performed (S8), and the unlock code number is erased.

  In addition, when the set password of the first type is “3131,” and the unlock code is changed to a 9-digit number string, for example, “543321345”, “* 1313154312345 #” may be input. If the second set password is “1919” and the second unlock code is to be deleted, “* 21919 #” may be entered.

  Next, an operation for confirming the unlock code number will be described. After the “#” key is pressed, any one of numbers 1 to 3 is continuously input. The symbol “#” is a symbol for shifting to the confirmation mode, and the next “n” key is a number that designates the number of the three types of unlocking code numbers. Further, the confirmation operation is performed by inputting “set password”, “unlocked password” and the end key “#”.

  Specifically, for example, when the second unlock code number whose unlock code number is “123456” is confirmed, it is as follows. If the set password is “9871”, “# 29871123456 #” is input from the main body operation unit 17. In response to this input, the CPU 18 determines that the unlock code number has been confirmed from the most significant digit “#” (S 1), and the second of the three types from the next “2”. It is determined that the password has been confirmed (S11).

  Subsequently, it is determined from “9871” in the third to sixth digits whether the set password is correct (S12). If the set password is incorrect, an error message is displayed on the display unit 15 and the confirmation mode is terminated ( S13). When it is determined that the number is correct, the last digit is determined from the position of “#” (S14). When there is no “#” in the last digit, as in the setting mode, an input error is displayed on the display unit 15, the buzzer 13 is sounded, and the confirmation mode is terminated (S15).

  If the last digit is “#” and this “#” is the seventh digit (YES in S16), the unlock code is read as “0000” and stored in the number storage unit 16. If the unlock code number is actually so (if it is not set), a message indicating that it is correct is displayed on the display unit 15, and the confirmation mode is terminated. However, if any number is set, it is not “0000”, so that an error is displayed, the buzzer 13 is sounded, and the process ends (S20).

  Here, since the last digit “#” is not the seventh digit but the thirteenth digit, it is determined that the seventh to twelfth digits are the unlock code number (S17), and a comparison determination is performed. If the input number matches the number stored in the number storage unit 16, it is determined that the number is correct, a message to the effect is displayed on the display unit 15, and the confirmation mode ends (S18). If it is wrong, the fact is displayed and the buzzer 13 is sounded to end the confirmation mode (S20).

As described above, when setting the unlock code number for unlocking the electric lock, it is necessary to input a set password number different from the unlock code number. Therefore, even if only the unlocking code number is known, the unlocking code number cannot be set or changed, and the unlocking code number cannot be set or changed even if the instruction manual for the electric lock of the same model number is obtained.
In addition, since multiple unlock code numbers can be set for the same electric lock, it is possible to assign an unlock code number to each user who operates the electric lock. Useful for time.

  Next, setting (and changing, erasing, checking) of the set password will be described based on the flow of FIG. First, after pressing the “*” key twice, continuously input any one of numbers 1 to 3 and input in order of “old set password number” “new set password number” and end key “#”. Setting operation is performed. The input of “**” is a symbol for shifting to the set password setting mode, and the next “n” key is a number that designates the number among the three types of unlocked passwords.

Specifically, the setting of the first unlocking code number “1234” is as follows. However, it is assumed that “0000” (erased state) is set as the set password in the initial state.
The main body operation unit 12 is operated to input “** 100001234 *” based on the above conditions. Upon receiving this input, the CPU 18 determines from the input of the upper two digits “**” that it is a setting password change (and change / erase) operation (S101), and enters the setting mode. Next, from “1” in the third digit, it is determined that it is the set password of the first unlocked password among the three types of unlocked password (S102).

  Subsequently, the following control is performed. It is judged whether “0000” in the 4th to 7th digits is the old set password or not (S103) and compared with the stored number (old set password) in the same manner as the unlocked password set above. If the number is different from the old set password, an error message is displayed on the display unit 15, the buzzer 13 is sounded, and the process ends without changing the set password (S104).

  Here, since the old set password is “0000”, it is determined to be correct, and it is then determined whether “#” indicating the last digit is in the 12th digit (S105). At this time, if there is no “#” in the 12th digit, an error message is displayed and the process ends. If there is “#” in the 12th digit, the 8th to 11th digits are determined as the newly set password and stored in the number storage unit 16 (S107). Then, a message indicating that the setting has been made is displayed on the display unit 15 and the process ends.

  The setting password changing operation is changed by inputting the old setting password by inputting “0000” and performing the setting operation. As an example, when the third set password is changed from “3131” to “8642”, “** 31318642 *” is input. Further, the erasure is performed by setting the newly set password to “0000” and overwriting again by the above setting operation.

  Confirmation of the set password set or changed in this way is performed in the following procedure. After depressing the “#” key twice, any number n from 1 to 3 is input. “##” is a symbol for shifting to the setting password confirmation mode, and the next “n” key is a number that designates the number of the three types of unlocked passwords. Then, after that, the “set password”, “unlocked password”, and the end key “*” are input to perform the confirmation operation.

  Specifically, the case where the first set password “4680” is confirmed is as follows. “## 14680 *” is input from the main body operation unit 12. As a result of this input operation, the CPU 18 determines from the upper two digits “##” to confirm the set password (S101), and from the next “1”, one of the three types of unlocked passwords. It is determined that it is confirmation of the set security code of the th unlock code (S109).

  Then, “4680” from the fourth digit to the seventh digit is read and it is determined whether or not it matches the stored set password (S111). If they do not match, an error message is displayed on the display unit 15, the buzzer 13 sounds and the confirmation mode ends (S112). If there is a match, it is then determined whether there is an “*” in the eighth digit (S113). If not, an error message is displayed on the display unit 15, the buzzer 13 is sounded, and the process ends (S114). If there is, a confirmation completion message is displayed and the confirmation mode is terminated (S115).

  In order to confirm that the password has been deleted, it is only necessary to input “END” key “*” with “0000” as the “set password”. For example, the third set password is deleted (“0000”). In order to confirm that it exists, “## 30000 *” may be input.

  In this way, the set security code itself can also be changed, and it can be changed to the same number for all unlocked security codes or can be changed periodically, making it easy to operate according to the installation environment of the electric lock. It is effective to maintain high security.

In the above embodiment, the “*” button and the “#” button are used for the mode setting symbol and the “#” button is used for the input end symbol. However, the present invention is not limited to this. Moreover, although the unlock code number and the set code number are composed only of numerals, they may be configured by mixing symbols. In this case, a larger number string can be set even if the number of digits is the same as that of a code number composed only of normally used numbers, and a code number that is difficult to decipher can be set. However, the code set as the input end symbol (“#” in the above embodiment) cannot be used for any password.
In addition, an independent set password is used for each unlock code, but the same set password may be used for all unlock codes of the same electric lock. It is only necessary to memorize the set password, and the burden on the administrator can be reduced.

  Next, another setting form of the set password will be described. In the above embodiment, the set password is set with an arbitrary 4-digit number, but the related unlock code is used, and the set password is configured by adding a number or a number string to this number string. You may do it. In this case, the unlock code number is set (and changed or deleted) as follows.

  First, after pressing the “*” key, enter any number n from 1 to 3 and enter the “set PIN”, “unlocked PIN to be used”, and the end key “#”. This is the same as the flow of setting the form. If the number string added as the second set password is “3579” and the unlock code before change is “12345”, the set password is “357912345”. When the new unlock code number is “54321”, the number string input when setting the unlock code number is “* 23579123455321 #”.

In this case, the unlock code number can be easily confirmed. Since the unlock code is included in the set password, the set password is confirmed. For example, when the additional number string of the third set password is “2536” and the third unlocked password is “13680”, the set password is “253613680”. In order to confirm this, "# 3253163680 #" may be input.
The setting (changing, erasing) of the additional number string can be performed in the same manner as the setting password changing (changing, erasing). Also, the set password can be confirmed in the same manner as the flow for checking the set password.

In this way, if the set security code is composed of a number sequence to which the unlocked security code is added, even if the set security code is composed of many number sequences that are difficult to decipher, many of the number sequences are related to Since it is a lock code number, an administrator can easily perform an input operation.
In addition, by setting the set password including the unlock code as described above, the additional number string is the same number string for all the unlock codes set for one electric lock. The burden on the administrator can be further reduced, and high security can be maintained.

In the above embodiment, three types of passwords can be set for one electric lock. However, the present invention is not limited to this, and only one or more may be provided. A plurality of unlocked passwords may be grouped and a set password may be set for each group.
Furthermore, although the set password number and the additional number string are treated as fixed 4 digits, the number is not limited to fixed digits, and the number of digits of the set password may be variable.
Moreover, although the electric lock apparatus provided with one electric lock was demonstrated, it can also be easily implemented to control several electric locks with one electric lock control apparatus 2. FIG.
