Embodiments of the present invention will now be described with reference to the drawings.
In FIG. 1, the structure of the locking / unlocking apparatus 1 of this invention is shown. The locking / unlocking device 1 is attached to a residential door 2 so as to be operable from both the indoor side and the outdoor side. In the drawing, (A) shows the outdoor side of the door 2, (B) shows the side end side of the door 2, and (C) shows the indoor side of the door 2. The locking / unlocking device 1 includes a main lock box 3, a sub lock box 4, a touch switch 5, and a control device 6.

  The main lock box 3 and the sub lock box 4 are each assembled inside the door 2, have dead bolts 7 and 8 that protrude from the side end face of the door 2 or can be accommodated therein, and are exposed to the indoor side. Manual operation units 9 and 10, key operation units 11 and 12 exposed to the outdoor side, and a motor (not shown) that drives dead bolts 7 and 8 are provided. The manual operation units 9 and 10 include thumb turns 13 and 14 that can be rotated by a user (resident), and indicators (monitor means) 15 and 16 each including a plurality of LEDs. The key operation units 11 and 12 can be rotated by inserting a predetermined key.

  The control device 6 includes, for example, a storage means 17 made of EEPROM, a working memory 18 made of RAM, an antenna device 20 that wirelessly communicates with a portable device 19 owned by each user, and a registration provided on the end face side of the door 2. And a switch 21. The control device 6 drives the dead bolts 7 and 8 based on various control information such as the thumbturns 13 and 14, the operation of the key operation units 11 and 12, the state of the touch switch 5, and the communication content with the portable device 19. Thus, the door 2 is locked or unlocked. In the locking / unlocking device 1 of the present embodiment, the control device 6 can not only lock or unlock the main lock box 3 and the sub lock box 4 together, but also the main lock box 3 and the sub lock box. Only one of 4 can be locked or unlocked.

  For the control of the locking / unlocking device 1, the control device 6 performs various data and control received from the main lock box 3, the sub lock box 4, the touch switch 5, or other components such as a sensor (not shown). Various control information such as a flag generated in the process is temporarily stored in the working memory 18. Further, the control device 6 indicates a drive information code indicating an operation condition for starting the locking / unlocking operation from the control information in the working memory 18 and what kind of control information is determined as a failure when the failure is detected. The failure information code is also stored in the EEPROM 17. The drive information code is overwritten in a predetermined area of the EEPROM 17 each time the motors of the main lock box 3 and the sub lock box 4 are driven, and only the latest information is stored. However, the failure information code is allowed by the capacity of the EEPROM 17. As long as there is a failure, they are added in the order in which they occurred. The EEPROM 17 also stores registration data such as an ID code of the portable device 19 owned by the resident. The control information stored in the working memory 18 is erased when the control device 6 is reset. However, the control information stored in the nonvolatile EEPROM 17 is retained without being erased even when the control device 6 is reset or the power is turned off. .

  In FIG. 2, the flow of the normal process which concerns on locking / unlocking of the door 2 of the control apparatus 6 of this locking / unlocking apparatus 1 is shown. The control device 6 confirms the state of the touch switch 5 in step S1. If the touch switch 5 is pressed in step S1, the process proceeds to step S2, performs touch switch processing described later, and returns to step S1. If the touch switch 5 is pressed in step S1, the process proceeds to step S3, where a call signal for specifying one portable device 19 is set, and a challenge signal including the set call signal is transmitted from the antenna device 20. In step S4, signal reception processing for receiving a response signal from the portable device 19 is performed. In this signal reception process, it is determined whether or not the received signal has a predetermined format. For example, if the received signal is not a predetermined bit length, the control device 6 determines that it is “communication abnormality failure”, and stores a communication abnormality failure information code, which is control information indicating the communication abnormality failure, in the EEPROM 17.

  Further, the control device 6 proceeds to step S5, and the portable device that responds to the challenge signal only when the ID code unique to the portable device 19 included in the received signal matches the ID code stored in the EEPROM 17 in advance. A signal authentication process for authenticating 19 is performed. Here, if the operating condition that the received ID code matches the stored ID code is satisfied, the control device authenticates the user and locks and unlocks the main lock box 3 and the sub lock box 4. If the received ID code does not match the stored ID code, the control device 6 determines that it is an “authentication mismatch failure” and stores an authentication mismatch failure information code indicating an authentication mismatch failure in the EEPROM 17.

  Note that the control device 6 of this embodiment stores the same data in three different areas of the EEPROM 17. For example, in step S4 or step S5 in which the ID code is read from the EPROM 17, the control device 6 reads and collates data from each of the three areas of the EEPROM 17, and if the data in the three areas do not match, the "EEPROM" The EEPROM 17 is determined to be “failure”, and an EEPROM failure information code indicating the EEPROM failure is stored in the EEPROM 17. As long as the data in two or more of the three areas match, the control device 6 continues the control based on a large number of data.

  If the signal authentication process of step S5 is complete | finished, the control apparatus 6 will progress to step S6, and will confirm whether the challenge signal is transmitted by the number of the portable devices 19 registered. When the challenge signal is not transmitted as many times as the number of registrations of the portable device 19, the process returns to step S1 and the processes from step S1 to S5 are repeated. If the challenge signal is transmitted to all the registered portable devices 19, the process proceeds to step S7 and waits until the next operation is performed.

  Next, FIG. 3 shows details of the touch switch process in step S3 of FIG. When the touch switch 5 is pressed in step S2 of FIG. 2, the control device 6 confirms whether or not the indoor button of the touch switch 5 is pressed in step S11 of FIG. If is not pressed, it is further checked in step S12 whether or not a button on the outside of the touch switch 5 has been pressed. If either the indoor or outdoor button of the touch switch 5 is pressed, the control device 6 proceeds to step S13 and confirms whether or not the touch switch 5 is continuously pressed for 30 seconds or more. . If the touch switch 5 is continuously pressed for 30 seconds or more, the control device 6 determines that there is a “touch switch abnormal failure”, proceeds to step S14, and shows control information indicating the touch switch failure in the EEPROM 17. The touch switch failure information code is stored. If it is determined in step S13 that the pressing time of the touch switch 5 is less than 30 seconds, the control device 6 reads the ID code from the EEPROM 17 in step S15, prepares the antenna output of the antenna device 20 in step S16, Returning to the normal processing of FIG.

  FIG. 4 shows the flow of control of the motor that drives the dead bolts 7 and 8 of the main lock box 3 and the sub lock box 4. This process is performed when the ID code received by the control device 6 is authenticated in the signal authentication process in step S5 of FIG. The control device 6 executes the motor drive process and motor drive process described later (FIG. 5) in step S21, and then, in step S22, the control information set in the working memory 18 in the motor stop process described later (FIG. 6). Are stored in the EEPROM 17 and a lock / unlock switch failure information code, which is one of the above, and a lock / unlock drive information code which is one of drive information set in the working memory 18 in the touch switch operation drive information processing (FIG. 8) described later. Let In step S23, it is confirmed whether or not there is a motor error flag set in the working memory 18 in a motor error process described later (FIG. 7). If the motor error flag is confirmed, the process proceeds to step S24, and the motor is driven in the direction opposite to the motor driving process executed in step S21. That is, in the case of a motor error, since there is a possibility that the dead bolt 7 or 8 is stopped between the locked position and the unlocked position, control is performed so as to return to the original position. In step S25, a motor error drive information code as drive information is stored in the EEPROM 17, and an error buzzer flag indicating abnormality is set in the working memory 18 in step S26.

  In step S27, the control device 6 further confirms whether or not the door 2 is open by a sensor (not shown). If the door 2 is open, an opening buzzer flag is set in the working memory 18 in step S28. Finally, in step S29, if a buzzer sound determined according to the set error or no error is set, a buzzer sound for notifying completion of locking or unlocking is output, and the motor control process is terminated. .

  FIG. 5 shows details of the motor drive processing executed in steps S21 and S24 in FIG. In the motor drive process, the control device 6 first checks in step S31 whether or not the door 2 is closed. If the door 2 is not closed, the control device 6 proceeds to step S32, and the main lock box 3 and the sub lock box. 4 is unlocked, that is, it is confirmed whether both dead bolts 7 and 8 are accommodated. If both the main lock box 3 and the sub lock box 4 are unlocked, the door opening buzzer flag is set in the working memory 18 in step S33, and the process is terminated.

  If the door 2 is closed in step S31, or if at least one of the main lock box 3 and the sub lock box 4 is locked (the dead bolts 7 and 8 are protruding) in step S32, the control device 6 proceeds to step S34. Then, touch switch operation drive information processing described later (FIG. 8) is performed. In step S35, a motor for driving the dead bolt 7 is operated in accordance with a detection result of a switch (not shown) that detects the position of the dead bolt 7 of the main lock box 3. In step S36, the sub lock box 4 A motor for driving the deadbolt 8 is operated in accordance with a detection result of a switch (not shown) that detects the position of the deadbolt 8.

  Further, in step S37, the control device 6 monitors voltage changes during driving of the dead bolts 7 and 8, and further monitors the drive time of the dead bolts 7 and 8 in step S38. If no voltage drop is detected during the driving of the dead bolts 7 and 8 and the driving of the dead bolts 7 and 8 is completed by a predetermined time, the process proceeds to step S39, and a motor stop process described later (FIG. 6) is executed. When a voltage drop is detected during the driving of the dead bolts 7 and 8 and when the driving of the dead bolts 7 and 8 is not completed by a predetermined time, the process proceeds to step S40, which will be described later (FIG. 7). ) Motor error processing is executed. If this motor stop process is completed, the process returns to the motor control process of FIG. 4 and proceeds to step S22.

  FIG. 6 shows details of the motor stop process. In the motor stop process, first, in step S41, the control device 6 confirms whether the motor drive command for the main lock box 3 and the sub lock box 4 is a drive in the locking direction or a drive in the unlocking direction. If it is not a locking direction driving command, that is, if it is an unlocking direction driving command, the processing from step S42 to step S51 is performed, and if it is a locking direction driving command, the processing from step S52 to step S61. I do.

  If the drive command is in the unlocking direction, in step S42, the state of the main unlocking switch (not shown) for detecting the unlocking of the main lock box 3 (storage of the dead bolt 7) is confirmed, and the main unlocking switch is turned off. If not, it is confirmed in step S43 whether a predetermined time has elapsed since the start of driving of the motor of the main lock box 3. If the predetermined time has elapsed, the output of the motor for unlocking the main lock box 3 is stopped in step S44, and the lock of the main lock box 3 (protrusion of the dead bolt 7) is detected in step S45. Check the state of the main locking switch shown. If the main locking switch is turned on despite the unlocking drive command, the main locking switch failure information code is set in the working memory 18 in step S46, and the process proceeds to step S47. If the main unlocking switch is on in step S42, the predetermined time has not passed in step S43, and the main unlocking switch is off in step S45, the process proceeds to step S47 as it is.

  In step S47, the state of a sub-unlocking switch (not shown) that detects unlocking of the sub-lock box 4 (accommodation of the dead bolt 8) is confirmed. If the sub-unlocking switch is off, the process proceeds to step S62. If the unlocking switch is on, it is confirmed in step S48 whether or not a predetermined time has elapsed since the start of driving of the motor of the sub lock box 4. If the predetermined time has elapsed, the output of the motor for unlocking the sub lock box 4 is stopped in step S49, and the lock of the sub lock box 4 (protrusion of the dead bolt 8) is not detected in step S50. Check the state of the illustrated sub-locking switch. If the sub-locking switch is on despite the unlocking drive command, the sub-locking switch failure information code is set in the working memory 18 in step S51, and the process proceeds to step S63. If the sub-unlocking switch is off in step S47, the predetermined time has not elapsed in step S49, and the sub-locking switch is on in step S50, the process proceeds directly to step S63.

  If it is a driving command in the locking direction, in step S52, the state of the main locking switch (not shown) for detecting the locking of the main lock box 3 (protrusion of the dead bolt 7) is confirmed. If the main locking switch is not OFF, In step S53, it is confirmed whether a predetermined time has elapsed since the start of driving of the motor of the main lock box 3. If the predetermined time has elapsed, the output of the motor for locking the main lock box 3 is stopped in step S54, and the unlocking of the main lock box 3 (storage of the dead bolt 7) is detected in step S55. Check the state of the main unlock switch shown. If the main unlocking switch is on despite the locking drive command, the main unlocking switch failure information code is set in the working memory 18 in step S56, and the process proceeds to step S57. If the main locking switch is on in step S52, the predetermined time has not elapsed in step S53, and the main unlocking switch is off in step S55, the process proceeds directly to step S57.

  In step S57, the state of a sub locking switch (not shown) that detects locking of the sub lock box 4 (protrusion of the dead bolt 8) is confirmed. If the sub locking switch is off, the process proceeds to step S62. If ON, it is checked in step S58 whether a predetermined time has elapsed since the start of driving of the motor of the sub lock box 3. If the predetermined time has passed, the output of the motor for locking the sub lock box 4 is stopped in step S59, and the unlocking of the sub lock box 4 (storage of the dead bolt 8) is detected in step S60. Check the state of the sub-unlock switch shown. If the sub-unlocking switch is turned on despite the locking drive command, the sub-unlocking switch failure information code is set in the working memory 18 in step S61, and the process proceeds to step S63. If the sub-locking switch is off in step S57, the predetermined time has not elapsed in step S59, and the sub-unlocking switch is on in step S60, the process proceeds directly to step S63.

  In step S62, it is checked whether or not a predetermined time has elapsed since the start of driving the motors of the main lock box 3 and the sub lock box 4. If the predetermined time has not elapsed, the process returns to step S41. The above control is repeated. In step S63, it is confirmed whether or not the motor of the main lock box 3 is still rotating. If the motor is rotating, the process proceeds to step S62. If the motor of the main lock box 3 is stopped in step S63, the process proceeds to step S64 to check whether the motor of the sub lock box 4 is rotating. If the motor of the sub lock box 4 is rotating, the process proceeds to step S62, and it is determined whether or not the processing from step S41 to step S61 is repeated. If it is determined in step S62 that the predetermined time has elapsed, the process proceeds to step S65, and motor error processing described later (FIG. 7) is executed.

  If the motors of the main lock box 3 and the sub lock box 4 are both stopped in step S63 and step S64, the process proceeds to step S66, and the drive command for the main lock box 3 and the sub lock box 4 is stopped. In step S67, the states of the main lock box 3 and the sub lock box 4 are confirmed, and both the main lock switch and the main lock switch are turned on, or both the sub lock switch and the sub lock switch are turned on. If so, the process proceeds to step S65 to execute a motor error process. If the two switches for detecting the positions of the dead bolts 7 and 8 are not turned on at the same time in the main lock box 3 and the sub lock box 4, the motor stop process is terminated, the process returns to the motor control process of FIG. move on. In step S22 of FIG. 4, when the lock / unlock switch failure information code is set in the working memory 18 in steps S46, S51, S56, and S61 of the motor stop process, the set lock / unlock switch failure information code is stored in the EEPROM 17 as shown in FIG. To remember.

  FIG. 7 shows details of the motor error processing. In this process, the control device 6 first checks in step S71 whether or not the error buzzer flag (step S26 in FIG. 4) is set in the working memory 18 in the motor control process described above. If the error buzzer flag is not set, it is checked in step S72 whether or not a motor drive command for the main lock box 3 has been issued. If there is no motor drive command for the main lock box 3, the sub lock box 4 is further checked in step S73. Check if there is a motor drive command. If the error buzzer flag is set in step S71, and if neither the motor drive command for the main lock box 3 or the sub lock box 4 is issued in steps S72 and S73, the process proceeds to step S74 and the main lock box is reached. 3 and the sub lock box 4 are stopped, and the process is terminated. If the motor drive command for either the main lock box 3 or the sub lock box 4 is issued in steps S72 and S73, the process proceeds to step S75, and the motor error flag and the error buzzer flag are set in the working memory 18. In step S76, the drive command for the main lock box 3 is deleted, and the motor drive output of the main lock box 3 is stopped. Furthermore, it progresses to step S77, it is confirmed whether predetermined time has passed since the motor drive start, and if predetermined time has not passed, the above-mentioned motor stop process (FIG. 6) will be performed again, and predetermined time will pass. If so, the process returns to step S71. Since the error buzzer flag is set in step S71, the process proceeds to step S74, the output to the main lock and the sub lock is stopped, and the process ends. When the motor error process is completed, the process returns to the motor control process of FIG. 4 and proceeds to step S22.

  FIG. 8 shows details of touch switch operation drive information processing (step S34 in FIG. 5) in the motor drive process. In this process, first, in step S81, the number of output of the call signal, that is, the number of transmission of the challenge signal is confirmed. If the number of calls is 0, this process is immediately terminated. If the number of calls is 1 or more and a challenge signal is transmitted, the process proceeds to step S82. In step S82, the number of calls is reconfirmed, and if the number of calls is one and the unlocking operation is performed, the process proceeds to step S83, and the main lock box 3 and the sub lock box 4 before the drive are both unlocked. It is confirmed whether or not. If both the main lock box 3 and the sub lock box 4 before being driven are unlocked, locking drive information indicating that the portable device 19 registered first in the working memory 18 is authenticated and locked in step S84. Code 1 is stored and the process is terminated. If the main lock box 3 and the sub lock box 4 are not unlocked and not locked before driving, the portable device 19 registered first in the working memory 18 is authenticated and unlocked in step S85. The unlocking drive information code 1 which is an information code indicating this is stored, and the process is terminated.

  If the number of calls is not 1 in step S82, the process proceeds to step S86 to check whether the number of calls is 2 or not. If the number of calls is two times, the locking drive information code indicating that the portable device 19 registered second in the working memory 18 is authenticated and locked in steps S87 to S89, as in steps S83 to S85. The unlocking drive information code 2 indicating that the portable device 19 registered second or second is authenticated and unlocked is stored, and the process is terminated.

  Further, in Step 90 to Step 112, similarly, when the portable device 19 registered in any of the third to eighth is authenticated and locked or unlocked, the locking drive information codes 3 to 8 and Any one of the unlocking drive information codes 3 to 8 is stored in the working memory 18 and the process is terminated. In the present embodiment, a maximum of eight portable devices 19 can be registered, and the latest drive information code indicating which portable device 19 has been authenticated and which operation to perform unlocking or locking is performed. Is overwritten in a predetermined area of the working memory 18 and stored. When this touch switch operation drive information processing is completed and the process returns to the motor drive process of FIG. 5, and when the motor drive process is completed and the process returns to the motor control process of FIG. 4, it is stored in the working memory 18 in step S22. The drive information code is overwritten in a predetermined area of the EEPROM 17 and stored. Thus, since only the latest drive information code is stored in the EEPROM 17, the capacity of the EEPROM 17 can be reduced. However, it is not always necessary to store only the latest drive information code, and the drive information code may be accumulated and stored in time series.

  Next, FIG. 9 shows a flow of a control program activation process of the control device 6 of the locking / unlocking device 1. This process is activated when the control device 6 is reset or when the registration switch 21 provided so as to be exposed at the side end surface of the door 2 is pressed. In this process, first, in step S121, it is confirmed whether or not the registration switch 21 has been pressed. If the registration switch 21 has been pressed, it is checked in step S122 whether or not the door 2 has been opened. If the door 2 is open, it is further confirmed in step S123 whether the button on the indoor side of the touch switch 5 is pressed or whether the button on the outdoor side of the touch switch 5 is pressed in step S124. When the registration switch 21 is pressed, the door 2 is open, and neither the indoor side button nor the outdoor side button of the touch switch 5 is pressed, the process proceeds to step S125, and a self-diagnosis mode (described later) 10) is started. When the execution of the self-diagnosis mode is completed, the process proceeds to step S126 to check whether the self-diagnosis has been completed in the self-diagnosis mode. If the self-diagnosis has not been completed, the process proceeds to step S127, and the registration mode for registering the portable device 19 is controlled. Whether the registration switch 21 is not pressed in step S121, whether the door 2 is closed in step S122, whether any button on the indoor side or outdoor side of the touch switch 5 is pressed in steps S123, S124, or in step S126 When it is confirmed that the self-diagnosis is not completed, the process proceeds to step S128 to clear the count of the number of times the registration switch 21 is pressed, and the process proceeds to step S129 to start the above-described normal processing (FIG. 2). Since the registration process of the portable device 19 is known, detailed description of the control is omitted.

  FIG. 10 shows the flow of control in the self-diagnosis mode in detail. When the self-diagnosis mode is activated, first, the control device 6 confirms the count of the number of times the registration switch 21 is pressed in step S131. If the number of times the registration switch 21 has been pressed is less than 3, the process proceeds to step S132, where 1 is added to the count of the number of times the registration switch 21 has been pressed, and the self-diagnosis mode is terminated without performing the following self-diagnosis. Then, the process returns to the above-described activation process (FIG. 9).

  If the number of times the registration switch 21 is pressed is 3 or more in step S131, the self-diagnosis in step S133 and after is performed. First, in step S133, the drive information code and the failure information code are read from the EEPROM 17. If the main lock switch failure information code is confirmed in step S134, the LED of the indicator 15 of the manual operation unit 9 of the main lock box 3 is blinked in a predetermined pattern indicating the main lock switch failure in step S135. Subsequently, similarly, if the main unlocking switch failure information code is confirmed in step S136, the LED of the display unit 15 is blinked in a pattern indicating the main unlocking switch failure in step S137. If the sub-locking switch failure information code is confirmed in step S138, the LED of the indicator 15 blinks in a pattern indicating the sub-locking switch failure in step S139, and if the sub-unlocking switch failure information code is confirmed in step S140. In step S141, the LED of the display unit 15 blinks in a pattern indicating a sub-unlocking switch failure. If the touch switch failure information code is confirmed in step S142, the LED of the display unit 15 is blinked in a pattern indicating the touch switch failure in step S143. If the communication abnormality failure information code is confirmed in step S144, the LED of the display unit 15 is blinked in a pattern indicating a communication abnormality failure in step S145. If the authentication mismatch failure information code is confirmed in step S146, the LED of the display unit 15 is blinked in a pattern indicating the authentication mismatch failure in step S147. If the EEPROM failure information code is confirmed in step S148, the LED of the display unit 15 is blinked in a pattern indicating the EEPROM failure in step S149. In step 150, the LED of the display unit 15 is blinked with a pattern indicating the latest drive information code stored in the EEPROM 17 among the drive information codes indicating the conditions for locking and unlocking. Finally, in step S151, the count of the number of times the registration switch 21 is pressed is cleared, the self-diagnosis is completed, and the process returns to the above-described activation process (FIG. 9).

  Through the above self-diagnosis process, a serviceman (or an operator such as a resident) can know the type of the most recent error that has occurred in the locking / unlocking device 1 and in what operation the error has occurred. . Specifically, it is possible to easily confirm which resident portable device 19 was operating when an error occurred, whether the error occurred during locking or unlocking, and the cause of the error Identification and countermeasure planning can be performed quickly.

  In the present embodiment, as the drive information code indicating the condition for performing the unlocking when the driving of the motor is completed, which portable device 19 and the locking drive information code for specifying the locking operation or the unlocking operation, In addition to the locking / unlocking operation started by such an artificial operation, the control device 6 automatically controls the drive of the motor and performs the locking / unlocking when the driving of the motor is completed. A drive information code for specifying the condition can also be stored in the EEPROM 17. As such a drive information code, drive information indicating that control is automatically performed when the door 2 is not opened or locked for 30 seconds after the user unlocks the locking / unlocking device 1. Code, when the user unlocks the locking / unlocking device 1 and detects that the door 2 has been opened and then closed again, it has been controlled to automatically lock 2 seconds after the door 2 is closed When the drive information code shown, the main lock box 3 and the sub lock box 4 are both locked, only one of the thumbturns 13 and 14 is rotated to the unlocked position for 18 seconds. When the other is not operated, the drive information code indicating that the control of picking measures for automatically returning both thumbturns 13 and 14 to the locked state, the main lock box 3 and the sub lock box 4 are both locked. If only one of the thumbturns 13 and 14 is rotated to the locked position, a drive information code indicating that the other thumbturn 13 or 14 has been controlled to be automatically locked is listed. . Even if any of these drive information codes is stored, if the motor drive is not completed, a motor error is detected and the reverse motor drive process (step S24 in FIG. 4) is executed. The EEPROM 17 stores a motor error drive information code indicating that locking / unlocking has been performed due to a motor error (step S25).

  Also, the locking / unlocking device 1 may be linked with a peripheral device such as a security camera, and can input information from the peripheral device as an operation condition for performing locking / unlocking. You may make it memorize | store in EEPROM17 as control information.
