Description

  The present invention relates to an electric lock system that unlocks or locks an electric lock when a user's personal identification number is acquired and normally authenticated.

  For example, in various doors of commercial buildings, public facilities, general houses, etc., an electric lock system having a high crime prevention property is employed in order to avoid the intrusion of a suspicious person. As this type of electric lock system, only when the password of the user is normally authenticated, an unlock signal or a lock signal is output, and driving means such as a motor and a solenoid are driven to advance and retract the dead bolt electrically. A device that performs unlocking or locking control of an electric lock is known.

  By the way, as a product that uses a numeric keypad of a fixed button for inputting a user's personal identification number, for example, an electric lock device disclosed in the prior art of Patent Document 1 below is known. As shown in FIG. 4, the electric lock device 51 includes an electric lock 52 provided on the door, an electric lock button 53 for unlocking the electric lock 52 from the inside, and an electric lock 52 for unlocking the electric lock 52 from the outside. A fixed button numeric keypad 54 for inputting a personal identification number, a controller 55, and a key operation unit 56 for unlocking the electric lock 52 of the door by using the key.

  In this electric lock device 51, a password (for example, an arbitrary combination number of 4 digits) that is arbitrarily selected and determined in advance by the user is registered in the controller 55 (target device), and the same as that registered. When the numeric key of the number is input from the numeric keypad 54, the electric lock 52 is unlocked.

  In addition to the fixed button described above, a numeric keypad using a liquid crystal panel is also known as the numeric keypad 54 for inputting the user's personal identification number, for example, as disclosed in Patent Document 2 below. In the numeric keypad using the liquid crystal panel disclosed in Patent Document 2, the arrangement of numbers on the liquid crystal panel changes randomly every time the user operates.

JP 11-159210 A JP 2000-99801 A

  However, in the conventional fixed button numeric keypad 54 disclosed in Patent Document 1, since each numeric key is fixed, the password is likely to be predicted by a third party from the position of the numeric key pressed by the user. In addition, since only the number key of the code number is always pressed, the code number is easily deciphered from the wear and dirt of the number key, and there is a problem in crime prevention.

  In addition, the numeric keypad using a liquid crystal panel changes the arrangement of numbers randomly and can change the display position of the numbers. Therefore, although the security can be improved as compared with the numeric keypad 54 of the fixed button, the user can change the PIN number. In addition, it is necessary to search for the position of the number, and there is a problem that operation time is required. Moreover, in order to control the liquid crystal panel, there is a problem that not only the hardware and software become complicated and cost increases, but also a backlight with high power consumption is required.

  Therefore, the present invention has been made in view of the above problems, and an object thereof is to provide an electric lock system that is easy to use for a user while maintaining security.

  Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings.

  The electric lock system 1 according to the present invention is employed in, for example, commercial buildings, public facilities, ordinary houses, etc., and controls the unlocking or locking of the electric lock when the user's password is acquired and normally authenticated. Yes, as shown in FIG. 1, a personal identification number input device 2 and an electric lock device 3 are provided.

  The personal identification number input device 2 includes a numeric keypad using a variable displayable printing technique, and includes a variable display unit 11, a switch unit 12, and a control circuit unit 13 provided in a casing (not shown).

  The variable display unit 11 is a plurality of characters (ideograms: numbers “0” to “9”) for inputting a password, which are printed at fixed positions in different arrangements so that light of different emission colors can be transmitted. It consists of a display board. In this example, as shown in FIG. 2, the arrangement of phonetic characters (alphabet letters “C”, “E”) is the same, and ideographic characters (numbers “0” to “9”) for entering a password are used. Two types of display boards (a first display board 11a and a second display board 11b) having different arrangements are provided as variable display portions 11 arranged before and after a housing (not shown).

  More specifically, as shown in FIG. 2, the first display board 11a has “1” and “2”, “3” and “4”, “5” and “5” in the width direction (arrow A in FIG. 2). 6 ”,“ 7 ”and“ 8 ”,“ 9 ”and“ 0 ”,“ C ”and“ E ”, respectively, form a set, and the length direction (from FIG. This is an arrangement configuration of characters by 6 rows and 2 columns aligned with arrow B). The first display panel 11a is coated with a blue paint so that blue light is transmitted from each character. As a result, when the blue light emitting element 21a of the surface light emitting unit 21 to be described later is driven to turn on, the first display plate 11a transmits blue light and turns “0” to “9”, “C”, and “E” into blue. indicate.

  The second display board 11b is disposed on the back side of the first display board 11a and, as shown in FIG. 2, “0”, “9”, “8” in the width direction (arrow A in FIG. 2). And “7”, “6” and “5”, “4” and “3”, “2” and “1”, “C” and “E”, respectively. Is a character arrangement configuration with 6 rows and 2 columns aligned in the length direction (arrow B in FIG. 2). The second display board 11b is coated with red paint so that red light is transmitted from each character. As a result, when the red light emitting element 21b of the surface light emitting unit 21 to be described later is turned on, the second display panel 11b transmits red light and turns “0” to “9”, “C”, and “E” into red. indicate.

  The switch unit 12 is configured by a touch panel or a membrane switch disposed on the back side of the variable display unit 11 with respect to the housing. The switch unit 12 has a contact at a position corresponding to each character (numbers “0” to “9” and alphabets “C” and “E”) of the variable display unit 11 in a one-to-one correspondence. When a character on the first display board 11a (or the second display board 11b) of the display unit 11 is pressed, a contact signal indicating the position of the pressed character is output to the control circuit unit 13.

  The control circuit unit 12 includes a surface light emitting unit 21, a driving unit 22, and a control unit 23 provided on a circuit board.

  The surface light emitting unit 21 is positioned at each character (numbers “0” to “9” and alphabets “C” and “E”) on the first display plate 11a (second display plate 11b) of the variable display unit 11. Correspondingly, it is composed of a light emitting element composed of a plurality of LEDs arranged in a matrix. In this example, it corresponds to the positions of numerals “0” to “9” and alphabets “C” and “E” on the first display board 11a (second display board 11b) of the variable display section 11 shown in FIG. A plurality of blue light emitting elements 21a and red light emitting elements 21b are arranged in a matrix to form the surface light emitting section 21.

  The drive unit 22 selectively drives the blue light emitting element 21 a and the red light emitting element 21 b to be turned on / off under the control of the control unit 23. In addition, the drive unit 22 is driven to be lit by switching from the blue light-emitting element 21a to the red light-emitting element 21b or switched from the red light-emitting element 21b to the blue light-emitting element 21a under the control of the control unit 23.

  The control unit 23 controls the drive unit 22 to turn on / off the light emission color and switch the light emission color of the blue light emitting element 21 a and the red light emitting element 21 b of the surface light emitting unit 21, and also a password based on the contact signal of the switch unit 12. Detection and verification, and output control of the unlock signal (lock signal) at the time of normal authentication of the password. In the control unit 23, a personal identification number (PIN: personal identification information) permitting the unlocking / locking of the electric lock 32 of the electric lock device 3 is registered in advance.

  More specifically, the control unit 23 turns blue every time the password input device 2 is activated by pressing a predetermined character or combination of characters on the variable display unit 11 (in this example, pressing the alphabet “C”). A control signal instructing switching of light emission is output to the drive unit 22 so that the light emitting element 21a is switched to the red light emitting element 21b, or the red light emitting element 21b is switched to the blue light emitting element 21a to emit light and drive the lighting.

  In addition, when a contact signal is input from the switch unit 12, the control unit 23 changes the pressed position by the contact signal and the light emission color of the light emitting element (blue light emitting element 21a or red light emitting element 21b) that is driven to light. The password entered by the user is detected by matching the position of the character.

  Then, the control unit 23 compares the detected personal identification number with a personal identification number registered in advance to determine its legitimacy, and when the detected personal identification number is normally authenticated, the light emitting element (blue light emitting element) that is currently lit and driven. 21a or the red light emitting element 21b) is output to the drive unit 22 and a unlocking signal (locking signal) for controlling the unlocking (locking) is output to the electric locking device 3. ing.

  The electric lock device 3 includes an electric lock control unit 31 and an electric lock 32. The electric lock control unit 31 exchanges information with the control unit 23 of the personal identification number input device 2. When an unlock signal (lock signal) is input from the control unit 23, the electric lock 32 is unlocked. A control signal for lock control (lock control) is output to the electric lock 32.

  The electric lock 32 uses a battery or a commercial power source as a drive source, and a control signal from the electric lock control unit 31 controls the energization of the drive means such as a motor or a solenoid, and a dead bolt connected to the drive means is a door. It is a conventionally well-known configuration that is locked or unlocked by advancing and retracting to the engagement hole of the frame, and is appropriately installed for each various doors to which the electric lock system 1 is adopted.

  Next, in the electric lock system 1 configured as described above, a series of operations until the user inputs the password and unlocks the electric lock 32 will be described with reference to FIG. Here, description will be made assuming that the password input device 2 is activated when the user presses the alphabet “C” of the variable display unit 11 at the time of password authentication.

  When the user A depresses the alphabet “C” of the variable display unit 11 to activate the password input device 2 (initial activation) (ST1), a contact signal indicating activation of the password input device 2 is controlled from the switch unit 12. Is output to the unit 23 (ST2). When a contact signal indicating activation of the password input device 2 is input from the switch unit 12, the control unit 23 outputs a control signal instructing light emission of the blue light emitting element 21a to the drive unit 22 (ST3). When the control signal instructing the light emission of the blue light emitting element 21a is input from the control unit 23, the driving unit 22 emits light to drive the blue light emitting element 21a. As a result, the numbers “0” to “9” and the alphabets “C” and “E” on the first display board 11a are displayed in blue (ST4).

  Then, the user A sequentially presses the numbers constituting the personal identification number among the numbers “0” to “9” of the first display plate 11a displayed in blue by the lighting driving of the blue light emitting element 21a, and then finally A character meaning confirmation is pressed to enter a password (ST5). For example, if the password is “1324”, the characters on the first display board 11a are pressed in the order of “1” → “3” → “2” → “4” → “E (confirmed)”. In response to the input of the code number, a contact signal indicating the code number is output from the switch unit 12 to the control unit 23 (ST6). If the user presses a number by mistake, pressing the alphabet “C” on the first display board 11a clears the pressed number and returns to the previous input state.

  When the contact signal indicating the security code is input from the switch unit 12, the control unit 23 collates the security code based on the contact signal (ST7). When the security code is normally authenticated, the control unit 23 An unlock signal is output to the electric lock control unit 31, and a control signal instructing to turn off the blue light emitting element 21a is output to the drive unit 22 (ST8). When the control signal instructing to turn off is input from the control unit 23, the driving unit 22 stops the light emission of the blue light emitting element 21a and drives to turn off (ST9). As a result, the activation of the password input device 2 is also stopped. At the same time, when an unlock signal is input from the control unit 23, the electric lock control unit 31 of the electric lock device 3 controls the unlocking of the electric lock 32.

  Next, when the user B follows the user A and presses the alphabet “C” of the variable display unit 11 to activate the personal identification number input device 2 (ST11), the personal identification number input device 2 is activated from the switch unit 12. The contact signal shown is output to the control unit 23 (ST12). When the contact signal indicating the activation of the password input device 2 is input from the switch unit 12, the control unit 23 switches the blue light emitting element 21a to the red light emitting element 21b and outputs a control signal for instructing light emission of the red light emitting element 21b. It outputs to the drive part 22 (ST13). When a control signal instructing light emission of the red light emitting element 21b is input from the control unit 23, the driving unit 22 emits light to drive the red light emitting element 21b. Thereby, the numbers “0” to “9” and the alphabets “C” and “E” on the second display plate 11b are displayed in red (ST14). And the process (ST5-ST9) similar to the process after the lighting drive of the blue light emitting element 21a mentioned above is performed for the process after the lighting drive of this red light emitting element 21b.

  As described above, in the electric lock system 1 of the present example, the light emission color of the light emitting element to be driven for light emission is switched every time the user presses a predetermined character on the variable display unit 11 to activate the personal identification number input device 2 (for example, , Each time the alphabet “C” is pressed, the display position of the numbers “0” to “9” is changed (from the first display board 11a to the second display board 11b). The second display board 11b is changed to the first display board 11a). As a result, the display position of the characters (numbers) is switched in accordance with the switching of the light emission color of the light emitting element, so that a certain level of security can be maintained. Further, after the personal identification number input device 2 is activated, it is not necessary to press a character other than the number related to the personal identification number. Furthermore, the variable display unit 11 is a character array switching by two types of display boards, the first display board 11a and the second display board 11b, and the display color also changes, so that the user can easily remember the character arrangement. In addition, it is easy to grasp the position of the number related to the password, and a user-friendly system can be constructed. In addition, since the process of switching the light emission color of the light emitting element of the surface light emitting unit 21, the hardware and software can be simplified, the cost can be reduced, and low power consumption can be realized. Furthermore, if the variable display unit 11 is configured to display in two colors (blue / red, blue / orange), the configuration can be simplified and it is possible to consider the color weak.

  In the above-described embodiment, the switch unit 12 has been described as being configured on the back side of the variable display unit 11 with respect to the housing. However, depending on the type of the switch unit 12 to be used, the switch unit 12 is mounted on the housing. On the other hand, the variable display unit 11 may be arranged on the front side. That is, the switch unit 12 may be configured to output a contact signal when each character of the variable display unit 11 is pressed.

  The variable display unit 11 has been described as a configuration in which the first display plate 11a is paired with the blue light emitting element 21a, and the second display plate 11b is paired with the red light emitting element 21b, but the present invention is not limited to this. It is not a thing. For example, the first display plate 11a is paired with a blue light emitting element, and the second display plate 11b is paired with an orange light emitting element, or a plurality of display plates each having a different character arrangement have different light emission colors. The light emitting element can be paired with each other. At that time, characters are printed on each display board with a paint of a color that matches the emission color to be transmitted.

  Further, in the embodiment described above, the password is collated by the controller 23 of the password input device 2, but the electric lock controller 31 of the electric lock device 3 is controlled by the controller 23 of the password input device 2. It is also possible to adopt a configuration in which the password number is input and the password number is verified. However, in order to prevent the security code leakage between the security code input device 2 and the electric lock device 3 and improve the security, the security code is collated by the control unit 23 of the security code input device 2. Is preferred.

  Further, in the above-described embodiment, the variable display unit 11 is configured by a two-color display plate, that is, the first display plate 11a applied with the blue paint and the second display plate 11b applied with the red paint, Although the case where the light emitting unit 21 is configured by the blue light emitting element 21a and the red light emitting element 21b has been described as an example, the present invention is not limited thereto. For example, the surface light emitting unit 21 is composed of three or more types of light emitting elements having different light emission colors, and a paint having a color matching the light emission color of the light emitting elements is applied to the display plate provided for each light emission color of the light emitting elements. The variable display unit 11 can also be used.

  Further, in the above-described embodiment, it is described that the blue light emitting element 21a emits light when the alphabet “C” is pressed in the initial state, and is driven to light. However, when the alphabet “C” is pressed in the initial state. The red light emitting element 21b may emit light and be lit.

  Further, when the blue light emitting element 21a or the red light emitting element 21b is lit and driven to light from the initial state, the contact signal when the alphabet “C” is pressed is used as a trigger, but the present invention is not limited to this. . For example, a contact signal when an alphabet “C”, “E” or numbers “0” to “9” are arbitrarily combined and pressed can be used as a trigger.

  Furthermore, the surface light emitting unit 21 is composed of a plurality of types of light emitting elements with different emission colors, and characters (ideographic characters (numbers), phonetic characters (alphabet), ideographic characters (kanji), etc.) are pressed in any combination. Each time a contact signal is input, the turn-on driving order of the light emitting elements having different emission colors can be switched. For example, when the light emitting elements of a plurality of light emitting colors are composed of a blue light emitting element, a red light emitting element, and an orange light emitting element, each time a contact signal when the alphabet “E” and the number “0” are pressed simultaneously is input, It is also possible to sequentially switch the emission color in the order of red and orange.

  As mentioned above, although the best form of the electric lock system 1 which concerns on this invention was demonstrated, this invention is not limited with the description and drawing by this form. That is, it is a matter of course that all other forms, examples, operation techniques, and the like made by those skilled in the art based on this form are included in the scope of the present invention.
