Description

  The present invention relates to an opening / closing device and can be applied to, for example, a shutter, a door, an automatic door, a window, an overhead door, a gate, a gate (for example, a gate of a parking lot), a roll screen (for example, a light shielding film), a blind, an awning device, and the like. .

  For example, periodic maintenance (maintenance) is required to operate an open / close body such as a shutter safely. In particular, in the case of an opening / closing body that is frequently used and has a fast opening / closing operation speed, such as a sheet shutter, the opening / closing operation of the opening / closing body may not operate properly depending on the usage mode or continuous use period of the opening / closing body. There is. Therefore, periodic maintenance is also necessary to prevent the deterioration of the opening / closing operation performance of the opening / closing body.

  Conventionally, the maintenance time of the opening / closing body is determined by, for example, a counter provided in a control panel for controlling the opening / closing operation of the opening / closing body counting the number of opening / closing operations of the opening / closing body, and the counter value is a specified number of times (for example, 100,000 times) The operator confirms whether or not the number of opening / closing operations has reached the predetermined number of times, and when the counter value reaches the specified number of times, the maintenance is required.

  A serviceman who receives a report from the owner or the like performs maintenance of the opening / closing body and resets the counter at the time of maintenance, thereby enabling detection of the next maintenance time.

Japanese Patent Application Laid-Open No. 2004-228561 describes a technique that allows a user to recognize a decrease in the battery voltage level of a battery-operated device that controls the opening / closing operation of the opening / closing body.
Japanese Patent No. 2697620

  As described above, conventionally, the maintenance timing of the opening / closing body is determined by checking the owner of the opening / closing body.

  However, the owner of the opening / closing body may find it troublesome to periodically check the maintenance timing of the opening / closing body through a counter. In addition, since the maintenance of the opening / closing body is not necessarily fatal that the opening / closing operation of the opening / closing body is stopped, the opening / closing operation itself of the opening / closing body does not occur even if the usage mode or the usage period of the opening / closing body exceeds the specified value. Often it is possible.

  For this reason, since the owner forgets to check the counter, or even if it is confirmed that the counter value exceeds the specified value, it appears that the opening / closing operation of the opening / closing body can be performed as usual, an announcement to the service person May not be made.

  On the other hand, even if the maintenance manager manages the maintenance timing of the opening / closing body, it is difficult to grasp the usage status of the opening / closing body, so it knows the maintenance time required according to the usage status of the opening / closing body. It can be difficult.

  Therefore, it is advantageous to have an opening / closing device that allows the owner or the like to easily recognize the maintenance timing of the opening / closing body while ensuring the safety of the opening / closing operation of the opening / closing body as much as possible.

  In order to solve such a problem, an opening / closing device of the present invention includes an opening / closing body driving means for driving the operation of the opening / closing body, and a drive for driving and controlling the opening / closing body driving means in a predetermined operation mode in accordance with an input instruction signal. Control means, management means for managing related information related to the operation of the opening / closing body, and normal operation when it is detected that a predetermined monitoring event has occurred based on the management result of the related information by the management means And an operation control means for controlling the drive control means in a maintenance notification operation mode in which the opening / closing body is driven in an operation mode different from the mode.

  According to the present invention, the occurrence of a predetermined monitoring event is detected based on the management result of related information related to the operation of the opening / closing body, and the opening / closing body is operated in an operation mode different from the operation mode of the normal opening / closing body. The user can recognize when maintenance is necessary through the operating mode of the opening / closing body.

(A) Embodiment Hereinafter, an embodiment of an opening and closing device of the present invention will be described with reference to the drawings.

  This embodiment demonstrates the case where it applies to the opening / closing apparatus which controls opening / closing operation | movement (for example, electric shutter etc.) of an opening / closing body by drive parts, such as a motor.

(A-1) Configuration of Embodiment FIG. 1 is a block diagram showing a main configuration of the opening / closing device of the present embodiment. In FIG. 1, the switchgear 1 according to the present embodiment includes a control panel 2, an operation instruction unit 3, a drive unit 4, a specified value setting unit 51, a temporary reset unit 52, a maintenance reset unit 53, a notification unit 54, and a display unit 55. At least.

  In addition, the control panel 2, the specified value setting unit 51, the temporary reset unit 53, the maintenance reset unit 53, the notification unit 54, and the display unit 55 are stored in a storage box that is fixedly installed near the opening / closing body (not shown). You may make it do.

  The control panel 2 receives an opening operation instruction signal, a closing operation instruction signal, or a stop operation instruction signal from the operation instruction unit 3, and controls the driving force of the driving unit 4 based on the received operation instruction signals. The control panel 2 manages one or a plurality of related information related to the operation of the opening / closing body, detects a monitoring event based on each management result, and controls the drive unit 4.

  The related information (also referred to as management information) related to the operation of the opening / closing body managed by the control panel 2 is, for example, the number of operations of the opening / closing body, the continuous use time of the opening / closing body, the remaining battery capacity of the drive unit 4, etc. The opening / closing body changes according to the use state of the opening / closing body from the time of new installation or the previous maintenance.

  In addition, the control panel 2 detects the occurrence of a monitoring event by setting one or a plurality of specified values for the related information and judging whether or not the management result exceeds the specified value. The drive unit 4 is controlled in an operation mode (maintenance notification operation mode) in which a maintenance event is detected upon detection of a monitoring event, and the maintenance time is notified.

  That is, the control panel 2 controls the drive unit 4 to perform a predetermined normal opening / closing operation before detecting a monitoring event, and performs an opening / closing operation different from the normal opening / closing operation after detecting the monitoring event. The drive unit 4 is controlled to do so. Control of the drive unit 4 by the control panel 2 at this time will be described later.

  In the situation where a monitoring event occurs, the function of the opening / closing body is not immediately lost, and the apparent operation of the opening / closing body operates as in normal times. That is, the monitoring event is detected when the related information (management information) reaches the specified value, but does not make the operation / function of the switchgear fatal.

  In the present embodiment, a case will be described in which the control panel 2 manages the number of operations of the opening and closing body and the number of continuous use as management information.

  The operation instructing unit 3 includes, for example, a switch for instructing an opening operation, a closing operation, and a stopping operation provided on a wall surface near the opening / closing body, a remote control transmitter and a remote control receiver for instructing an opening operation, a closing operation, and a stopping operation. This group is applicable. The operation instruction unit 3 gives a corresponding operation instruction signal to the operation instruction input unit 23 when operated by the user.

  The drive unit 4 corresponds to, for example, a motor that drives the opening and closing operations of the opening / closing body and a brake that stops the operation of the opening / closing body. The drive unit 4 drives the opening / closing body according to the control of the control panel 2.

  The specified value setting unit 51 sets specified values for management information managed by the control panel 2 and includes, for example, an input unit (for example, a numeric keypad) and a setting switch. The specified value setting unit 51 is a setting unit that stores the specified value captured from the input unit in the storage unit 29 of the control panel 2 after switching a setting switch or the like, for example. The specified value setting unit 51 can be used when a set specified value is input by an operation of a service person or the like, and the set specified value once set is changed or deleted. In addition, the specified value input from the specified value setting unit 51 can be input for each management information (in the case of this embodiment, the number of operations and the continuous use time), and one or more specified values for each management information. It is possible to set a value.

  For example, when the management information is the number of operations, the specified value for the number of operations can be set to 100,000 times, for example. Also, for example, when the management information is set as the continuous use time, the specified value for the use time can be set to one year, for example.

  For example, when the management information is the number of operations, a plurality of specified values can be set such that the first specified value is 100,000 times and the second specified value is 200,000 times.

  The temporary reset unit 52 is an operation unit that can be operated by the user in order to temporarily reset the operation mode of the control panel 2 that controls the operation of the drive unit 4 in the maintenance notification operation mode. This is reset only for a predetermined period after the maintenance notification operation in consideration of the possibility that the user may inconvenience the use of the opening / closing member while the maintenance notification operation mode is maintained. The temporary reset unit 52 may be a remote operation means including, for example, a remote control transmitter and a remote control receiver, and the temporary reset operation may be a remote operation.

  The maintenance reset unit 53 is an operation unit operated by a service person performing maintenance. When the maintenance reset unit 53 is operated, the management information (number of operations and / or continuous use time) of the control panel 2 is reset. Since the management information is less than the specified value by resetting, the control panel 2 is changed from the maintenance notification operation mode to the normal operation mode. The maintenance reset unit 53 may be a remote transmission unit including a remote control transmitter and a remote control receiver.

  The display unit 55 displays that it is a maintenance time based on detection of a monitoring event by the control panel 2, and corresponds to a lamp, for example. Further, the notification unit 54 notifies the maintenance time, and corresponds to, for example, a buzzer.

  Next, the main internal configuration of the control panel 2 will be described in detail with reference to FIG. As shown in FIG. 1, the control panel 2 includes a set specified value input unit 21, a drive control output unit 22, an operation instruction input unit 23, a temporary reset input unit 24, a maintenance reset input unit 25, a control unit 26, and the number of operations. At least a counter 27, a continuous use time management unit 28, and a storage unit 29 are provided.

  The set specified value input unit 21 has an interface function for giving the specified value received from the specified value setting unit 51 to the control unit 26 and storing it in the storage unit 29. The operation instruction input unit 23 has an interface function that receives various operation instruction signals from the operation instruction unit 3 and gives them to the control unit 26. The temporary reset input unit 24 has an interface function for supplying the control unit 26 with the temporary reset signal given from the temporary reset unit 52. The maintenance reset input unit 25 has an interface function of giving the reset signal given from the maintenance reset unit 53 to the control unit 26.

  The operation number counter 27 counts the opening / closing operation of the opening / closing body. The operation number counter 27 may count each of the opening operation and the closing operation, or may count the reciprocating operation between the opening operation and the closing operation. The operation counter 27 resets the counter value under the control of the control unit 26 when receiving a reset signal from the maintenance reset unit 53.

  The continuous use time management unit 28 corresponds to, for example, a timer, and manages the continuous use time of the opening / closing body. When the continuous use time management unit 28 receives a reset signal from the maintenance reset unit 53, the continuous use time management unit 28 resets the management time under the control of the control unit 26.

  The drive control output unit 22 receives an operation control signal from the control unit 26, and controls the drive unit 4 according to the operation control signal. The drive control output unit 22 corresponds to, for example, an inverter.

  For example, when the control unit 26 performs control in the normal operation mode, the drive control output unit 22 receives an operation control signal indicating the normal operation mode from the control unit 26, and the frequency (for example, 60 Hz) of the motor drive signal corresponding to the operation control signal. ) To the drive unit 4. For example, when the control unit 26 performs control in the maintenance notification operation mode, an operation control signal indicating the maintenance notification operation mode is received from the control unit 26, and the frequency (for example, 30 Hz) of the motor drive signal corresponding to the operation control signal is driven. Part 4 is given.

  In the case of the above example, since the opening / closing operation of the opening / closing body is proportional to the motor drive frequency, the speed of the opening / closing operation of the opening / closing body can be halved.

  The storage unit 29 corresponds to, for example, a RAM or a ROM, and stores processing programs executed by the control unit 26 and data necessary for processing.

  In the present embodiment, the processing programs stored in the storage unit 29 include a normal operation mode program 291a, one or a plurality of maintenance notification operation mode programs 291b, and a temporary reset operation mode program 291c. Further, as the data stored in the storage unit 29, there are setting specified value data 292a and 292b. In the present embodiment, the setting specified value data 292a for the number of operations is set, and the setting specified value data 292b for the continuous use time.

  The control unit 26 corresponds to, for example, a microprocessor (CPU), and mainly performs an opening / closing control operation of the opening / closing body and a management operation of management information. Of course, the control unit 26 may be configured by hard logic (in this case, the storage unit 29 is a setting unit).

  When the control unit 26 receives the operation instruction signal from the operation instruction unit 3, the control unit 26 determines whether or not the management information is greater than or equal to the specified value. If the management information is less than the specified value, the operation control in the normal operation mode according to the operation instruction signal is performed. A signal is given to the drive control output unit 22, and if it is equal to or greater than the specified value, an operation control signal for the maintenance notification operation mode corresponding to the operation instruction signal is given to the drive control output unit 22.

  That is, the control unit 26 detects the occurrence of a monitoring event when it is determined that the management information is equal to or greater than the specified value, and notifies the user of the maintenance timing from the normal operation mode to the maintenance notification. The drive control output unit 22 is controlled by switching to the operation mode.

  Here, the normal operation mode is an operation mode in which the opening / closing body is opened, closed, and stopped according to the operation instruction signal, and is controlled at normal times. The normal operation mode is an operation mode based on the normal operation mode program 291a in the storage unit 29.

  The maintenance notification operation mode is an operation mode in which control is performed in an operation mode different from the operation mode of the opening / closing body in the normal operation mode when the occurrence of a monitoring event is detected. The maintenance notification operation mode is an operation mode based on the maintenance notification operation mode program 291b in the storage unit 29.

  In the case of the present embodiment, the control unit 26 controls the drive control output unit 22 in the maintenance notification operation mode, so that the frequency and / or sending time of the motor control signal given to the drive unit 4 by the drive output control unit 22 is the normal operation mode. It is different from the case of. This is because the frequency of the motor control signal is proportional to the operating speed of the opening / closing body, and the sending time of the motor control signal is proportional to the operating time of the opening / closing body.

  As a result, the operating speed and / or operating time of the opening / closing body driven by the drive unit 4 is different from that in the normal operation mode, and the user who sees the opening / closing body that operates differently can recognize the maintenance time.

  The operation mode of the opening / closing body that operates when the control unit 26 controls in the normal operation mode is referred to as a normal operation mode, and the operation mode of the opening / closing body that operates when the control unit 26 controls in the maintenance notification operation mode. Is called the operation mode of maintenance notification.

  It is desirable that the operation mode of the opening / closing body in the maintenance notification operation mode is lower than the normal operation mode in consideration of safety and user convenience.

  Further, a plurality of maintenance notification operation modes having different operation modes of the opening / closing body may be set, and may be operated differently depending on the type of the monitoring event to be generated. In this case, the association between the maintenance notification operation mode and the monitoring event may be set in advance or may be selectable by the user.

  Below, the operation mode example of an opening-closing body by the control part 26 controlling in a maintenance notification operation mode is demonstrated.

  For example, in the maintenance notification operation mode, the opening / closing body is operated at a speed different from the normal opening / closing operation speed, or the operation of the opening / closing body is stopped once without fully opening or closing immediately, and then fully opening or closing. Or, for example, an extra operation mode that does not operate in a normal state, such as moving up and down a predetermined number of times during the opening operation and closing operation and then fully opening and closing it, may be added. As a result, the user can notice the opening / closing body that operates differently and can know the maintenance time.

  In setting the maintenance notification operation mode, it is preferable to reduce the performance of the opening / closing operation as compared with the normal opening / closing operation in consideration of safety and user convenience.

  For example, when changing the operating speed of the opening / closing body, safety may not be ensured if the operating speed of the opening / closing body is made higher than normal, so that the operation speed may be slowed down slowly. For example, when performing an opening operation and / or a closing operation, the user temporarily stops at a height that allows the user to enter the room (for example, about 2 m from the ground) and / or a height that cannot enter the room (for example, about 10 cm from the ground). Alternatively, it may be moved up and down a predetermined number of times and then fully opened and fully closed.

  This makes it possible to notify the maintenance time while maintaining safety and the like. In addition, reducing the performance leads to, for example, extending the driving life of the motor and other opening / closing members, and can provide a safe operation until actual maintenance work is performed.

  In addition, the maintenance notification operation mode may be set differently for each type of management information and for each type of monitoring event that occurs. Also, a plurality of operation modes with different operation modes of the opening / closing body may be set, and the user may select from the plurality of operation modes.

  For example, when the first specified value is reached, the operation speed is reduced, and when the second specified value is reached, the operation speed is further reduced, or when the first specified value is reached, for example. Alternatively, the opening / closing body may be temporarily stopped for the opening / closing operation when the operation speed is slowed down and the second specified value is reached. Further, when the first specified value is reached, for example, it may be moved up and down by one reciprocation, and when it reaches the second specified value, for example, it may be moved up and down by three reciprocations.

  Of course, when the set specified value is reached, the operation mode of the opening and closing body can be freely selected from a plurality of operation modes. Thereby, the user can recognize appropriately that the maintenance time has passed.

  Next, a specific example in the case where the control unit 26 performs control in the maintenance notification operation mode will be described.

  For example, the speed of the opening and closing operations of the opening / closing body can be made slower than normal. Further, it is possible to select only one of the operation speeds of the opening operation and the closing operation.

  In this case, it is possible by setting the motor drive frequency of the operation control signal given to the drive unit 4 to a predetermined frequency lower than normal (for example, 30 Hz when the normal time is 60 Hz). This is because the opening / closing operation is proportional to the motor driving frequency. Further, when setting in multiple stages according to the set number of specified values or the number of operation instructions, it is possible to set a plurality of frequencies (for example, 45 Hz, 30 Hz, 15 Hz,... When the normal time is 60 Hz).

  Further, for example, the opening height of the opening / closing body can be limited. In this case, it is possible to shorten the transmission time of the operation control signal given to the drive unit 4 from the normal time (for example, 2 seconds when the normal transmission time is 1 minute). This is because the opening / closing operation is proportional to the time during which the operation control signal is given to the drive unit 4. Further, in the case of multi-stage setting, it is possible to set a plurality of transmission times (when the normal time is 1 minute, 5 seconds, 4 seconds, 3 seconds,...). The opening / closing body can be set to stop at a predetermined height from the ground.

  In addition, when an opening operation instruction or a closing operation instruction is received from the operation instruction unit 3, an operation control signal is given to the driving unit 4 for 2 seconds, for example, the opening / closing body is opened or closed and stopped once, and further operation is performed. A control signal may be given to the drive unit 4 so that the opening / closing body is fully opened or fully closed.

  For example, the speed of the opening or closing operation of the opening / closing body can be changed. In this case, the operation control signal given to the drive unit 4 operates, for example, “60 Hz motor drive frequency for 1 second, 30 Hz motor drive frequency for 1 second, 60 Hz motor drive frequency for 1 second,. The speed can be changed.

  Further, for example, the opening / closing body may be moved up and down. For example, when an opening operation instruction is received, the opening / closing body is made to “upward operation, lowering operation, upper operation,...”, Or when an opening operation instruction is received, the opening / closing body is moved to “downward operation, upper operation, lower operation,. " In the case of multi-stage setting, the speed at which the opening / closing body is moved upward or downward or the opening height may be changed in multiple stages.

  The temporary reset operation mode is an operation mode based on the temporary reset operation mode program 291c stored in the storage unit 29 when the temporary reset signal is received from the temporary reset unit 52 to temporarily cancel the maintenance notification operation mode.

  The temporary reset operation mode only needs to be able to cancel the maintenance notification operation mode during the period until maintenance is performed in consideration of user convenience.

  Further, the operation mode of the opening / closing body by the control of the temporary reset operation mode may be an operation mode in which the maintenance time is notified again after the maintenance notification operation mode is temporarily canceled.

  For example, the control unit 26 may return to the normal operation mode by a temporary reset, and the performance of the opening / closing operation may be reduced in multiple steps according to the number of operation instructions after a predetermined management period. About this operation | movement aspect, the opening / closing operation | movement speed | rate, the restriction | limiting of an opening height, etc. which were mentioned above, or the aspect which combined these can be made. Thereby, after the temporary reset and a predetermined period of time elapses, the operating performance of the opening / closing body deteriorates, so that the user can recognize the maintenance time again.

(A-2) Operation | movement of embodiment Next, the operation | movement which recognizes the maintenance time of the opening-closing body by the opening / closing apparatus of this embodiment is demonstrated in detail with reference to drawings.

  In the following, the setting operation of the specified value, the opening / closing operation based on the monitoring result of the number of operations, the opening / closing operation based on the monitoring result of the usage time, and the resetting operation will be described in order.

(A-2-1) Specified Value Setting Operation First, the specified value setting operation will be described with reference to FIG. The specified value can be set by the same setting operation for both the specified value for the number of operations and the specified value for the usage time.

  The service person inputs a specified value to the specified value setting unit 51 by a predetermined operation.

  The specified value is input by, for example, turning on a setting switch (not shown) of the specified value setting unit 51 so that the specified value setting unit 51 and the set specified value input unit 21 are connected. The specified value captured by the input unit is supplied to the set specified value input unit 21. When a plurality of specified values are input, the specified values can be input one by one by the same setting operation.

  The input specified value is given to the control unit 26 via the set specified value input unit 21 of the control panel 2 (S1).

  The set specified value given to the control unit 26 is given from the control unit 26 to the storage unit 29, and is stored in a predetermined storage area as set specified value data 292a or 292b (S2).

  Thereby, the setting of the prescribed value for the monitoring event that occurs according to the management information is completed.

(A-2-2) Opening / closing operation based on operation count management result Next, an opening / closing operation based on the operation count management result will be described with reference to FIG. In FIG. 3, a description will be given of application in a case where a predetermined value (for example, 100,000 times) for the number of operations of the opening / closing body is one and the maintenance notification operation mode is one that makes the opening / closing operation speed of the opening / closing body slower than normal. .

  When the operation instruction unit 3 is operated by the user, an operation instruction signal is given from the operation instruction unit 3 to the control unit 26 via the operation instruction input unit 23 of the control panel 2 (S3).

  When the operation instruction signal is given to the control unit 26, the control unit 26 compares the counter value indicated by the operation number counter 27 with the set specified value data 292a of the storage unit 29, and the counter value reaches the set specified value 292a. It is determined whether or not (S4).

  When the control unit 26 determines that the counter value of the operation number counter 27 is less than the set specified value data 292a, the control unit 26 performs the normal operation mode (S5). Then, an operation control signal in the normal operation mode is given to the drive control unit output unit 22 from the control unit 26 that controls in the normal operation mode.

  When the operation control signal in the normal operation mode is supplied from the control unit 26 to the drive control output unit 22, an operation control signal corresponding to the normal operation mode is supplied from the drive control output unit 22 to the drive unit 4. When the operation control signal in the normal operation mode is supplied to the drive unit 4, the drive unit 4 is driven according to the operation control signal, and the opening / closing operation of the opening / closing body is performed (S6).

  For example, in the normal operation mode, assuming that the drive unit 4 is driven at a motor drive frequency of 60 Hz, for example, to open and close, the drive control output unit 22 applies a 60 Hz frequency to the drive unit 4. A motor drive signal is provided. Thereby, the opening operation | movement and closing operation | movement according to the operation | movement instruction | indication signal from the operation instruction | indication part 3 can operate | move as usual.

  If it is determined in S4 that the counter value indicated by the operation counter 27 is equal to or greater than the set specified value data 292a, it is considered that maintenance is necessary, and the control unit 26 changes from the normal operation mode to the maintenance notification operation mode. (S7). Then, an operation control signal in the maintenance notification operation mode is given from the control unit 26 to the drive control output unit 22.

  When the operation control signal in the maintenance notification operation mode is given to the drive control output unit 22, the operation control signal corresponding to the maintenance notification operation mode is given from the drive control output unit to the drive unit 4, and driving is performed according to the operation control signal. The part 4 is driven, and the opening / closing operation of the opening / closing body is performed (S8).

  For example, in the maintenance notification operation mode, if it is predetermined that the drive unit 4 is driven at a motor drive frequency of 30 Hz, for example, a motor drive signal having a frequency of 30 Hz is sent from the drive control output unit 22 to the drive unit 4. Is given. Accordingly, the opening operation or the closing operation can be performed in accordance with the operation instruction signal from the operation instruction unit 3 and at a slower opening / closing operation speed than in the normal operation.

  In S6 and S8, when the opening / closing body is opened or closed, the counter value of the operation counter is incremented, and the next operation instruction signal is received from the operation instruction unit 3 (S9).

  Even in the case of the opening / closing operation in the maintenance notification operation mode, the opening / closing body can be opened and closed. This is because the maintenance notification operation mode is intended to allow the user to recognize the maintenance time of the opening / closing body by changing the operation mode of the opening / closing body.

(A-2-3) Opening / Closing Operation Based on Usage Time Management Result Next, the opening / closing operation based on the usage time management result will be described with reference to FIG.

FIG. 4 shows a case where the specified value for the number of operations of the opening / closing body is one, and the application when the maintenance notification operation mode limits the opening height of the opening / closing body will be described.

  When the operation instruction unit 3 is operated by a user, an operation instruction signal is given from the operation instruction unit 3 to the control unit 26 via the operation instruction input unit 23 of the control panel 2 (S10).

  When the operation instruction signal is given to the control unit 26, the control unit 26 compares the management time managed by the continuous use time management unit 28 with the set specified value data 292b of the storage unit 29, and the management time is set to the set specified value. It is determined whether or not 292b has been reached (S11).

  When the control unit 26 determines that the management time of the continuous use time management unit 28 is less than the set specified value data 292b, the control unit 26 performs the normal operation mode (S12), and the operation control signal of the normal operation mode is received. It is given to the drive control unit output unit 22.

  When the operation control signal in the normal operation mode is supplied from the control unit 26 to the drive control output unit 22, an operation control signal corresponding to the normal operation mode is supplied from the drive control output unit 22 to the drive unit 4. When the operation control signal in the normal operation mode is given to the drive unit 4, the drive unit 4 is driven according to the operation control signal, and the opening / closing operation of the opening / closing body is performed (S13).

  For example, in the normal operation mode, if the drive time of the drive unit 4 is predetermined as, for example, 1 minute, the motor control signal is continuously supplied from the drive control output unit 22 to the drive unit 4 for 1 minute. Thereby, according to the operation instruction | indication signal from the operation instruction | indication part 3, an opening operation | movement or closing operation | movement sufficient to fully open or close an opening-closing body can be made.

  If it is determined in S11 that the management time of the continuous use time management unit 28 is equal to or greater than the set specified value data 292b, it is considered that maintenance is necessary, and the control unit 26 performs the maintenance notification operation from the normal operation mode. The mode is changed (S14). Then, an operation control signal in the maintenance notification operation mode is given from the control unit 26 to the drive control output unit 22.

  When the operation control signal in the maintenance notification operation mode is given to the drive control output unit 22, the operation control signal corresponding to the maintenance notification operation mode is given from the drive control output unit to the drive unit 4, and driving is performed according to the operation control signal. The unit 4 is driven, and the opening / closing operation of the opening / closing body is performed (S15).

  For example, in the maintenance notification operation mode, for example, if the opening / closing operation time is predetermined as 2 seconds, for example, a motor drive signal is continuously given from the drive control output unit 22 to the drive unit 4 for 2 seconds. . As a result, the opening / closing operation of the opening / closing body can be made shorter in response to the operation instruction signal from the operation instruction unit 3 than in the case of the normal operation. That is, when the opening instruction signal is given from the operation instruction unit 3, the opening height of the opening / closing body is stopped low, and when the closing action instruction signal is given, the opening is stopped at a position where the opening height of the opening / closing body is high. Can be made. When the closing operation instruction signal is given, the opening / closing body may be stopped once and then fully closed.

(A-2-4) Reset Operation Next, the operation of resetting the maintenance notification operation mode to the normal operation mode when the opening / closing body operates in the maintenance notification operation mode will be described with reference to FIG.

  The operation mode reset includes a reset (main reset) performed by a service person after maintenance or during maintenance, and a temporary reset (user reset) performed by a user.

  Basically, it is desirable that the operation mode be restored by this reset. However, until the maintenance is performed, in consideration of the user's inconvenience due to the opening / closing body operating in the maintenance notification operation mode, the user reset temporarily. It is possible to return to normal operation.

  In FIG. 5, the control unit 26 is in the maintenance notification operation mode based on the monitoring of the number of operations or the usage time of the opening / closing body (S20).

  When the control unit 26 is in the maintenance notification operation mode, the control unit 26 determines whether a reset signal is given from the maintenance reset unit 53 (S21).

  When a maintenance man performs a predetermined operation on the maintenance reset unit 53 and a reset signal is given from the maintenance reset unit 53 to the control unit 26 via the maintenance reset input unit 25 of the control panel 2, the control unit 26 resets the control unit 26. The signal is captured, and the counter value of the operation counter 27 and / or the management time of the continuous use period management unit 28 are reset (S25).

  As a result, the counter value and / or the tube time becomes less than the set specified value 292a and / or 292b, so that the operation mode can be switched to the normal operation mode.

  In S21, when the reset signal is not given from the maintenance reset unit 53 to the postnatal part 26, it is determined whether or not the temporary reset signal is given from the temporary reset unit 52 (S22). The operation mode at this time is the maintenance notification operation mode.

  When a temporary operation of the temporary reset unit 52 is performed by the user and a temporary reset signal is given from the temporary reset unit 52 to the control unit 26 via the temporary reset input unit 24 of the control panel 2, the temporary reset signal is generated by the control unit 26. The control unit 26 performs the temporary reset operation mode (S23). That is, the operation mode becomes the normal operation mode.

  On the other hand, when the temporary reset signal is not given from the temporary reset unit 52 to the control unit 26, the maintenance notification operation mode is maintained as it is.

  In S23, the temporary reset operation mode is performed to return to the normal operation mode, but the period of operation in the normal operation mode is predetermined. This period is a period in which the period from when the maintenance notification mode is entered until the opening / closing body is maintained can be guaranteed.

  When the normal operation mode in the temporary reset operation mode is performed, the control unit 26 determines whether or not the period of transition to the normal operation mode is a predetermined period or longer (S24).

  If the control unit 26 determines that the period of transition to the normal operation mode is less than the predetermined period, the normal operation mode is performed as it is. If the control unit 26 determines that the period of transition to the normal operation mode is equal to or longer than the predetermined period, the control unit 26 returns to the maintenance notification operation mode again (S24).

  Thereby, the user can recognize the necessity of maintenance of an opening-closing body again.

(A-3) Effects of the Embodiment As described above, according to the present embodiment, the control panel 2 opens / closes different from the normal opening / closing operation of the opening / closing body by detecting a monitoring event that does not make the opening / closing operation of the opening / closing body fatal. By controlling so that the opening and closing is performed, the user can recognize the maintenance time of the opening and closing body.

(B) Other Embodiments In the description of the above-described embodiments, various modified embodiments have been referred to, but the following modified embodiments are further exemplified.

(B-1) In the above-described embodiment, a case has been described in which a preset maintenance notification operation mode is associated with each specified value set in each monitoring event and each management information. , Set multiple different maintenance notification operation modes in a unified manner, and each time a monitored event reaches multiple specified values (in order of occurrence of monitoring events), perform the maintenance notification operation mode with higher priority step by step. It may be.

  For example, in the maintenance notification operation mode, the first priority is one in which the opening / closing operation speed is ½ of the normal time, the second priority is a restriction on the opening height of the opening / closing body, and the third priority is It is possible to set a uniform maintenance notification operation mode such that the opening / closing operation speed is ½ that of the normal time and the opening height of the opening / closing body is limited.

(B-2) In the above-described embodiment, the temporary reset operation in the temporary reset unit 52 has been described as being performed manually by a user or the like, but may be performed automatically. In this case, the control unit 26 controls to switch from the normal operation mode to the maintenance notification operation mode based on the monitoring result, and enters the temporary reset operation mode after a predetermined period (for example, several hours) that allows the user to recognize the maintenance time. Switching control may be performed.

  Further, the operation method of the temporary reset unit 52 and the maintenance reset unit 53 may be based on the input of a personal identification number in order to prevent an operation by a third party. Further, in order to prevent free operation of the temporary reset unit 52, it may be kept secret until a maintenance request is made, and the operation method may be communicated to the user from the administrator side. Moreover, you may make it set the reset method from which the operation method of the temporary reset part 52 differs for every opening / closing operation | movement of an opening-closing body (namely, for every operation mode of the control part 26).

(B-3) In the above-described embodiment, as the management information related to the opening / closing operation of the opening / closing body, the case where the number of operations of the opening / closing body and the continuous use time have been described has been described. Any indicator that can change depending on the use state or use of the switchgear can be widely applied. For example, a continuous non-use period in which the opening / closing operation of the switchgear is not instructed may be monitored.

  In this case, for example, it is possible to monitor whether or not a predetermined period has elapsed since the timer opened / closed immediately before the opening / closing body. Then, the control panel may control an operation mode in which the shutter sheet is slightly raised or lowered slightly when the non-use period of the opening / closing body has passed a predetermined period.

(B-4) In the above-described embodiment, the case where the maintenance time of the opening / closing body (for example, shutter sheet) is recognized has been described. However, the maintenance time of each component (component) constituting the opening / closing device is recognized. It may be. In this case, it is possible to set a maintenance notification operation mode of a different operation mode according to the maintenance time of each component. Configuration requirements of the switchgear include, for example, a motor for the switchgear, an inverter, a sequencer, a counter, a lamp, various sensors (for example, an obstacle detection sensor), an operation instruction unit (including a remote control unit), a roller, a spring, a hinge, and a chain , Etc.
