[Prior art]
For example, an electric shutter installed in a factory or warehouse has two types of operation modes, an automatic mode and a manual mode. The automatic mode is a mode that automatically controls the opening and closing of the electric shutter when the sensor detects a moving object in the vicinity of the electric shutter. The manual mode is used to operate the user's remote control transmitter and fixed operation unit. In response to this, the electric shutter is controlled to be opened and closed.
[0003]
Such switching between the two types of modes is performed by a mode switch provided on a control panel on which a circuit for controlling the operation of the shutter is mounted. In order to prevent destruction and the like, the control panel is generally provided in a shutter case that houses the shutter in an open state.
[0004]
In the case of a shutter installed so as to operate in the automatic mode, the manual mode can be switched to, for example, a maintenance inspection.
[0005]
The necessity of such maintenance and inspection is determined by the number of shutter operations, etc., but a display that displays such parameters indicating the amount of operation is also provided in a place that cannot be seen from the outside, such as a control panel. (See Patent Document 1).

This embodiment is for an electric shutter.
[0015]
(A-1) Configuration of the embodiment
FIG. 1 is a block diagram showing the overall configuration of the switchgear instruction transmission / reception system of this embodiment.
[0016]
1, this switchgear operation mode switching system 1 includes a remote controller transmitter (switcher operation mode instruction transmitter) 10, a remote controller receiver (switcher operation mode instruction receiver) 20, a control panel 30, a motor 40, a display. Device (display device for switchgear) 50, moving body detection sensor 60, and the like. Note that the remote control receiver 20 and the control panel 30 may be combined.
[0017]
The remote control transmitter 10 includes an operation unit 11, a transmission control unit 12, a transmission unit 13, a transmission antenna 14, and a notification unit 15.
[0018]
As shown in FIG. 2, the operation unit 11 includes three instruction keys 11 a to 11 c for instructing “opening operation”, “stopping operation”, and “closing operation” of the shutter, respectively. The signal is given to the transmission control unit 12.
[0019]
Here, as shown in FIG. 2, the opening operation instruction key 11a and the stopping operation instruction key 11b are connected by a connection notation including a character string “auto / manual”, and the opening operation instruction key 11a and the stopping operation instruction key 11b. It is clarified that the simultaneous operation of these causes the operation mode to be switched. Further, as shown in FIG. 2, the stop operation instruction key 11b and the closing operation instruction key 11c are also connected by a connection notation including a character string “interlock on / off”. It is clarified that the simultaneous operation of 11c causes the on / off switching of the interlock to be executed.
[0020]
The transmission control unit 12 controls the entire remote control transmitter 10 and is composed of, for example, a microcomputer.
[0021]
The transmission control unit 12 receives an instruction signal for an opening operation, a closing operation, or a stop operation from the operation unit 11, assembles an original transmission signal (for example, serial transmission data: see FIG. 3), and gives it to the transmission unit 13. In addition, when the transmission control unit 12 receives an instruction signal for an opening operation, a closing operation, or a stop operation from the operation unit 11, the transmission control unit 12 causes the notification unit 15 to perform a notification operation.
[0022]
FIG. 3 is an explanatory diagram showing a data format of an original transmission signal transmitted from the remote control transmitter 10 to the remote control receiver 20.
[0023]
The original transmission signal includes a flag sequence F indicating the head of the original transmission signal, an identification code ID of the remote control transmitter 10 that is the transmission source, and information to be transmitted (for example, an opening operation instruction, a closing operation instruction, a stop operation instruction, an operation The information part INF includes a mode switching instruction, an interlock valid / invalid switching instruction, and the like.
[0024]
The transmission control unit 12 of the remote control transmitter 10 gives the original transmission signal (hereinafter referred to as a frame as appropriate) shown in FIG. The identification code ID of the remote control transmitter 10 is incorporated in advance in the transmission control unit 12 of the remote control transmitter 10.
[0025]
In the case of this embodiment, the transmission control unit 12 uses a single instruction signal from the opening operation instruction key 11a, the stop operation instruction key 11b, and the closing operation instruction key 11c as a frame as an operation instruction assigned to the key. An instruction signal for simultaneous input from the opening operation instruction key 11a and the stop operation instruction key 11b is generated to create a frame as an instruction to switch the operation mode, and the simultaneous input from the stop operation instruction key 11b and the stop operation instruction key 11b. The instruction signal creates a frame as an instruction to switch interlock validity / invalidity.
[0026]
The transmission unit 13 modulates the frame given from the transmission control unit 12 to make a signal (radio transmission signal) in a radio frequency band (for example, about 426 MHz) and radiates it from the transmission antenna 14 to space. The transmission unit 13 incorporates a band pass filter and a power amplifier as necessary. Although the modulation scheme of the original transmission signal is arbitrary, for example, an ASK modulation scheme or an FSK modulation scheme can be applied.
[0027]
As described above, the transmission antenna 14 radiates a wireless transmission signal to space. The transmission antenna 14 is provided, for example, inside a housing that constitutes the remote control transmitter 10.
[0028]
The notification unit 15 performs a notification operation that allows the user to recognize that the instruction signal for the opening operation, the closing operation, and the stop operation from the operation unit 11 has been received under the control of the transmission control unit 12. For example, as shown in FIG. 2, the notification unit 15 is a single light emitting element common to each of the keys 11 a to 11 c described above, and visually notifies by lighting or blinking. In addition, visual notification by a character such as a liquid crystal display may be performed, or auditory notification such as a buzzer or a speaker may be performed. In addition, it may appeal to other human senses such as vibration.
[0029]
The remote control receiver 20 includes a reception antenna 21, a reception unit 22, a reception control unit 23, an ID memory 24, and the like.
[0030]
The remote control receiver 20 is connected to the control panel 30 and is provided together with the control panel 30 and the motor 40, for example, in a shutter case.
[0031]
The receiving antenna 21 captures a radio wave from the remote control transmitter 10 and converts it into an electric signal (wireless reception signal). Since the remote control transmitter 10 can take various positions, the reception antenna 21 is preferably provided in a form that protrudes to the outside in consideration of reception sensitivity. Moreover, since the remote control transmitter 10 can take various positions as the receiving antenna 21, for example, an antenna having a non-directional property or a considerably wide directivity range is applied.
[0032]
The receiving unit 22 demodulates the radio reception signal given from the receiving antenna 21 and obtains a frame (demodulated signal) that the remote control transmitter 10 is about to transmit. The signal is given to the reception control unit 23. The receiving unit 22 includes a band pass filter having a radio frequency band as a pass band, a preamplifier, and a low pass filter having a band of a demodulated signal as a pass band as necessary.
[0033]
The reception control unit 23 controls each unit of the remote control receiver 20, and is composed of, for example, a microcomputer.
[0034]
When a registration unit (not shown) instructs the remote control receiver 20 to register an identification code (hereinafter referred to as ID) of the remote control transmitter 10 that can be instructed, the reception control unit 23 takes in the ID and stores the ID. It is stored in the memory 24.
[0035]
Further, the reception control unit 23 decodes the demodulated signal (frame) from the receiving unit 22 and determines whether the ID included in the demodulated signal is registered in the ID memory 24 or not. It is confirmed whether the transmitter 10 can issue an instruction for the shutter. Thereafter, the control unit 23 recognizes the contents (opening operation instruction, closing operation instruction, stop operation instruction, operation mode switching instruction, interlock valid / invalid switching instruction) designated in the frame, and the recognized contents are controlled by the control panel. 30 is notified.
[0036]
As described above, since the remote control transmitter 10 repeatedly transmits frames, the reception control unit 23 receives a predetermined number of demodulated signals (frames) having the same contents transmitted by the remote control transmitter 10 within a predetermined time ( If it is obtained, the above-described control is performed with the demodulated signal being effective.
[0037]
In addition, the reception control unit 23 is configured such that when the remote control transmitter 10 as the transmission source cannot issue an instruction for the shutter, or when the instruction content from the remote control transmitter 10 is inconsistent with the current shutter state (for example, the shutter If the opening operation is instructed in the open state, the instruction content is ignored.
[0038]
As described above, the ID memory 24 stores the ID of the remote control transmitter 10 (not limited to one) that can give a valid instruction to the remote control receiver 20, for example, an EEPROM or the like. Non-volatile memory.
[0039]
The control panel 30 includes an operation control unit 31, a motor drive unit 32, a state memory 33, a mode switch 34, a mode fixing switch 35, an interlock switch 36, a display driver 37, a sensor interface unit 38, and an interlock line interface. The unit 39 is provided.
[0040]
The operation control unit 31 controls each unit of the control panel 30 and is composed of, for example, a microcomputer.
[0041]
The operation control unit 31 controls the operation of a shutter (not shown), controls the display content of the display 50, and controls the arbitration of the operation with another interconnected control panel (not shown). Is. The specific control contents will be clarified in the function explanation of other components and the operation explanation described later.
[0042]
The motor drive unit 32 controls the motor 40 under the control of the operation control unit 31 to open, stop, or close a shutter (not shown).
[0043]
The state memory 33 is composed of, for example, a non-volatile memory such as an EEPROM, and whether the operation mode is the automatic mode or the manual mode, whether the interlock is valid or invalid, and the operation of the shutter. The number of times is memorized. The contents stored in the state memory 33 are updated as appropriate by the operation control unit 31 and read out by the operation control unit 31.
[0044]
The mode change switch 34 is, for example, a push button, and instructs the operation control unit 31 to switch the operation mode between the automatic mode and the manual mode.
[0045]
As the mode changeover switch 34, the position of the operation element such as a dip switch may directly indicate the type of the mode, but in this embodiment, the mode changeover is also performed from the remote control transmitter 10 side. Since it can be instructed, for example, a push button is applied as described above in order to prevent inconsistency between the type of mode currently valid and the position of the operation element.
[0046]
The mode fixing switch 35 is a dip switch, for example, and instructs whether to prohibit switching between the automatic mode and the manual mode (fix the mode) or to allow switching between the modes. That is, when the mode fixing switch 35 is fixedly set, even if an instruction to switch between the automatic mode and the manual mode is given from the remote control transmitter 10 side or the mode changeover switch 34, the instruction is ignored by the operation control unit 31. When the mode fixing switch 35 is set to allow switching, the operation control unit 31 switches between the automatic mode and the manual mode when the remote control transmitter 10 side or the mode switching switch 34 is instructed. Switch.
[0047]
As the mode fixing switch 35, for example, a push switch may be applied to store in the state memory 33 whether the mode is fixedly set or whether switching is allowed.
[0048]
The interlock changeover switch 36 is formed of, for example, a push button, and instructs the operation control unit 31 to switch between the validity and invalidity of the interlock.
[0049]
As the interlock changeover switch 36, the position of the operation element such as a DIP switch may directly indicate whether the interlock is valid or invalid. In the case of this embodiment, the remote control transmitter 10 side may also be used. Since it is possible to instruct whether the interlock is valid or invalid, a push button, for example, is applied as described above in order to prevent contradiction between the validity or invalidity of the current interlock and the operator position.
[0050]
The display device drive unit 37 drives the display device 50 under the control of the operation control unit 31 to make the display content of the display device 50 desired by the operation control unit 31.
[0051]
The sensor interface unit 38 takes in the detection signal of the moving body detection sensor 60 and gives it to the operation control unit 31. The operation control unit 31 processes the detection signal from the sensor interface unit 38 as valid only in the automatic mode. As will be described later, the moving body detection sensor 60 is provided both upstream and downstream of the shutter opening, and the sensor interface unit 38 is also provided corresponding to each moving body detection sensor 60.
[0052]
The interlock line interface unit 39 accommodates an interlock line interconnected with another control panel for shutters, and is controlled with respect to the other control panel under the control of the operation control unit 31. In addition to notifying the prohibition and prohibition release of the corresponding shutter operation, the control unit 31 receives a notification from the other control panel such as the prohibition and prohibition release of the shutter operation.
[0053]
The motor 40 executes an opening operation, a stopping operation, or a closing operation of the shutter according to a driving signal from the motor driving unit 32. The type of power transmission mechanism that transmits the rotational force of the motor 40 to the shutter (such as its rotating shaft) is not limited. For example, a mechanism using a gear mechanism, a mechanism using a chain and a sprocket, a belt and a pulley are used. Anything may be used.
[0054]
The display device 50 is provided at a position where the user or maintenance staff can visually check the display contents without opening the shutter case body or its inspection opening lid, such as the shutter case surface or the shutter guide rail surface. .
[0055]
For example, as shown in FIG. 4, the display 50 can display a predetermined number of characters such as numbers, a character display unit 51 such as a liquid crystal display, and whether the automatic mode is set as the operation mode (lights up) manually. A mode display light-emitting element 52 that is an LED or the like indicating whether the mode is set (off), and an interlock display light-emitting element 53 that is an LED or the like indicating whether the interlock is enabled (lighted) or invalid (off). The error display light-emitting element 54, which is an LED or the like, indicating whether an error has occurred (lighted) or not (light-off), and whether the moving body detection sensor 60 is detecting (lighted) or not (light-off). And a sensor state display light-emitting element 55 made of an LED or the like.
[0056]
Under the control of the operation control unit 31 of the control panel 30, the character display unit 51 displays, for example, a code that defines the number of shutter operations and an error type when an error occurs, and an identification name.
[0057]
The moving body detection sensor 60 is, for example, a photoelectric sensor, and is provided on each of the upstream and downstream sides of the shutter opening, and detects the passage of the moving body.
[0058]
(A-2) Operation of the embodiment
Next, the operation of the switchgear operation mode switching system 1 according to the embodiment having the above configuration will be described.
[0059]
First, the operation of the remote control transmitter 10 (particularly the operation of the transmission control unit 12) will be described with reference to the flowchart of FIG.
[0060]
The transmission control unit 12 of the remote control transmitter 10 waits for the operation unit 11 to be operated (S1). When there is a single key operation or simultaneous operation of a plurality of keys, the type of operation key is selected. It discriminate | determines (S2) and performs the transmission control operation | movement according to an operation key (S3-S7). Note that the transmission control unit 12 causes the notification unit 15 to perform notification indicating that the operation is recognized during a period in which the key operation is performed.
[0061]
Specifically, when the opening operation instruction key 11a is operated, the transmission control unit 12 creates an opening operation instruction frame (original transmission signal), gives it to the transmission unit 13 for transmission (S3), and stops operation. When the instruction key 11b is operated, a stop operation instruction frame is generated and given to the transmission unit 13 for transmission (S4). When the close operation instruction key 11c is operated, a stop operation instruction frame is generated. When the opening operation instruction key 11a and the stop operation instruction key 11b are operated simultaneously, a frame for mode switching instruction is generated and given to the transmission unit 13 for transmission (S6). When the stop operation instruction key 11b and the closing operation instruction key 11c are simultaneously operated, a frame for interlock valid / invalid switching instruction is generated and given to the transmission unit 13 for transmission (S7). Note that the transmission control unit 12 ignores simultaneous operations other than the above.
[0062]
Next, the operation of the remote control receiver 20 (particularly the operation of the reception control unit 23) will be described with reference to the flowchart of FIG.
[0063]
The receiving unit 22 of the remote control receiver 20 demodulates the radio reception signal when a radio reception signal of a predetermined level or higher is given from the reception antenna 21, obtains a demodulated signal (frame), and sends it to the reception control unit 23. give.
[0064]
The reception control unit 23 waits for the input of such a frame (S11). When a frame is input, whether the ID included in the signal matches that registered in the ID memory 24 or not. In other words, it is determined whether or not the remote control transmitter 10 as the transmission source can issue an instruction for the shutter (S12).
[0065]
If the ID included in the input frame does not match that registered in the ID memory 24, the reception control unit 23 ignores the frame input this time.
[0066]
On the other hand, when the ID included in the frame is registered in the ID memory 24, the reception control unit 23 decodes (determines) the content of the information inserted in the information part of the original transmission signal. (S13).
[0067]
When the information in the information section of the frame indicates a stop operation, an opening operation or a closing operation, the reception control unit 23 gives a signal indicating that to the control panel 30 (S14 to S16), and inputs the frame. Return to the waiting state.
[0068]
In addition, when the information in the information section of the frame instructs the switching of the operation mode, the reception control unit 23 waits for the reception of that type of frame to exceed a predetermined time (for example, 2 seconds), and operates A signal indicating mode switching is given to the control panel 30 (S17, S18), and the process returns to the frame input waiting state.
[0069]
Further, the reception control unit 23 waits for the reception of that type of frame to exceed a predetermined time (for example, 2 seconds) when the information in the information unit of the frame instructs switching of the interlock validity / invalidity. Then, a signal representing switching of interlock validity / invalidity is given to the control panel 30 (S19, S20), and the process returns to the frame input waiting state.
[0070]
If the reception continuation time of the frame for instructing the switching of the operation mode or the frame for instructing the switching of the interlock is invalid does not satisfy the predetermined time, the reception control unit 23 ignores the current reception. To return to the frame input wait state.
[0071]
For example, when switching the operation mode according to the instruction manual of the remote control transmitter 10, the simultaneous operation of the opening operation instruction key 11a and the stop operation instruction key 11b is performed for 2 seconds or more, and the interlock is effective. When performing the invalid switching, the user is made aware that the simultaneous operation of the stop operation instruction key 11b and the closing operation instruction key 11c is performed for 2 seconds or more.
[0072]
When the remote control transmitter 10 detects simultaneous operation of the opening operation instruction key 11a and the stop operation instruction key 11b, or when detecting simultaneous operation of the stop operation instruction key 11b and the closing operation instruction key 11c, remote control transmission is performed. The frame 10 may be transmitted after confirming an operation for a predetermined time or longer on the device 10 side. Further, when the remote control transmitter 10 detects the simultaneous operation, even if the operation period is shorter than the predetermined time that the remote control receiver 20 determines to be effective, the frame may be transmitted continuously for a predetermined time or more. . Furthermore, although the simultaneous operation time is shorter than a predetermined time (for example, 2 seconds) that the remote control receiver 20 determines to be effective, if the simultaneous operation period exceeds another predetermined time (for example, 1 second), the remote control receiver 20 is effective. You may make it transmit a flame | frame continuously more than predetermined time to judge.
[0073]
Next, the operation of the control panel 30 (particularly the operation of the drive control unit 31) will be described with reference to the flowcharts of FIGS.
[0074]
The drive control unit 31 waits for an input of a signal that is required to start a control operation (S31 to S33), and when such a signal is input, a subroutine process corresponding to the signal transmission source is performed. Perform (S34-S36).
[0075]
Specifically, when a signal is input from the remote control receiver 20 (S31), the drive control unit 31 performs a subroutine process for signal input from the remote control receiver 20 (S34), and from the sensor interface unit 36. When a sensor detection signal is input (S32), a subroutine process is performed when the sensor detection signal is input (S35), and when a signal is input from any of the built-in switches 34 and 36 (S33 (FIG. 10)). S33A, S33B)), a subroutine process for switch input is performed (S36).
[0076]
FIG. 8 is a flowchart showing details of a subroutine process for inputting a signal from the remote control receiver 20.
[0077]
When receiving a signal from the remote control receiver 20, the drive control unit 31 determines the content of the input signal (S41).
[0078]
When the input signal has a content that directly instructs the operation of the shutter, that is, when the input signal indicates an opening operation, a stopping operation, or a closing operation, the mode stored in the state memory 33 is the automatic mode. It is discriminated whether the operation mode is the manual mode or not (S42). The drive control unit 31 performs separate control in the open operation, the stop operation, or the close operation (although the process branches). ), Because of space limitations, FIG. 8 shows the same processing flow.
[0079]
If the storage mode of the state memory 33 is the automatic mode, the drive control unit 31 returns to the main routine shown in FIG.
[0080]
In contrast, when the storage mode of the state memory 33 is the manual mode, the drive control unit 31 determines whether the interlock validity / invalidity information stored in the state memory 33 is valid or invalid. (S43). If the interlock is valid, the drive control unit 31 takes in information from the interlock line interface unit 39 to determine whether another control panel prohibits the operation of the shutter (S44).
[0081]
When the interlock is valid and the other control panel prohibits the operation of the shutter, the drive control unit 31 returns to the main routine shown in FIG.
[0082]
On the other hand, when the interlock is invalid or when the interlock is valid, but the other control panel allows the operation of the shutter, the drive control unit 31 controls the motor 40, The instructed shutter operation is executed (S45). Further, depending on the content of the instruction, the drive control unit 31 updates the number of shutter operations stored in the state memory 33 (S46), and also updates the number of shutter operations displayed on the display device 50 (S47).
[0083]
It should be noted that the number of shutter operations may be incremented by 1 when the opening operation is activated, or may be incremented by 1 for the opening operation and the subsequent closing operation, and is incremented by 1 for each of the opening operation and the closing operation. Further, it may be incremented by 1 at the timing when full opening or full closing is recognized, not at the time of activation.
[0084]
In addition, the drive control unit 31 controls the interlock line interface unit 39 in parallel with the control of the motor 40 or waits for the end of the control of the motor 40 and when the interlock is valid, The control panel is notified of the operation prohibition and prohibition release (operation allowance) of other shutters determined in relation to the operation of the shutter (S48, S49). Then, the process returns to the main routine shown in FIG. For example, when the shutter is opened, the opening operation of the other shutter is prohibited, and when the shutter is fully closed, the opening operation of the other shutter is allowed (inhibited).
[0085]
If the input signal from the remote control receiver 20 is an instruction to switch the operation mode, the drive control unit 31 captures the state of the mode fixing switch 35 and determines the state (S50). If the mode fixing switch 35 has instructed fixing, the drive control unit 31 ignores the input of the signal instructing switching of the operation mode, and immediately returns to the main routine shown in FIG.
[0086]
On the other hand, if the mode fixing switch 35 is in a state that allows the mode to be changed, the drive control unit 31 switches the storage mode of the state memory 33 to the other mode (S51) and the mode after the switching. The state of the mode display light emitting element 52 of the display 50 is changed so as to correspond to (S52), and the process returns to the main routine shown in FIG.
[0087]
For example, when the operation mode switching instruction signal is given from the remote control receiver 20 while the manual mode is stored in the state memory 33, the drive control unit 31 updates the storage mode of the state memory 33 to the automatic mode. At the same time, the mode display light-emitting element 52 of the display 50 is changed from the unlit state to the lit state. On the other hand, when the operation mode switching instruction signal is given from the remote control receiver 20 while the automatic mode is stored in the state memory 33, the drive control unit 31 updates the storage mode of the state memory 33 to the manual mode. At the same time, the mode display light-emitting element 52 of the display 50 is changed from the lit state to the unlit state.
[0088]
If the input signal from the remote control receiver 20 is a content instructing switching of the interlock validity / invalidity, the drive control unit 31 switches the interlock validity / invalidity information in the state memory 33 to the other content (S53). Then, the state of the interlock display light emitting element 53 of the display 50 is changed so as to correspond to the contents after switching (S54), and the process returns to the main routine shown in FIG.
[0089]
For example, when interlock invalidity is stored in the state memory 33 and the interlock valid / invalid switching instruction signal is given from the remote control receiver 20, the drive control unit 31 stores the contents stored in the state memory 33. The lock is updated to be valid, and the interlock display light emitting element 53 of the display 50 is changed from the unlit state to the lit state. On the other hand, when the interlock valid is stored in the state memory 33 and the interlock valid / invalid switching instruction signal is given from the remote control receiver 20, the drive control unit 31 stores the contents stored in the state memory 33. In addition to updating the interlock to invalid, the interlock display light emitting element 53 of the display device 50 is changed from the lit state to the unlit state.
[0090]
FIG. 9 is a flowchart showing details of subroutine processing when a sensor detection signal is input.
[0091]
When the sensor detection signal is input, the drive control unit 31 first determines whether the mode stored in the state memory 33 is the automatic mode or the manual mode (S61).
[0092]
In the manual mode, the drive control unit 31 ignores the input of the sensor detection signal and immediately returns to the main routine shown in FIG.
[0093]
In the manual mode, the sensor interface unit 38 may be controlled so that a sensor detection signal is not input from the sensor interface unit 38 to the drive control unit 31. For example, a gate circuit may be provided and the gate circuit may be closed.
[0094]
On the other hand, in the automatic mode, the drive control unit 31 determines the operation content of the shutter based on the current shutter state, the past sensor detection signal input status, and the like (S62). For example, if the source of the sensor detection signal this time is a downstream moving body detection sensor, and the shutter is currently fully open based on the past sensor detection signal from the upstream moving body detection sensor, It is determined to perform the closing operation.
[0095]
After this determination, the drive control unit 31 performs substantially the same operation (S43 to S49) as when the shutter operation is instructed from the remote control transmitter 10 side, and returns to the main routine shown in FIG. However, the drive control unit 31 also performs control to turn on the sensor state display light-emitting element 55 of the display device 50 during input of the sensor detection signal or for a predetermined time from the start of input (may be blinking).
[0096]
FIG. 10 is a flowchart showing details of subroutine processing when signals from switches (push switches) 34 and 36 built in the control panel 30 are input.
[0097]
When a signal is input from the mode changeover switch 34 (Yes in S33A), the operation control unit 31 waits for the signal input to exceed a predetermined time (for example, 2 seconds) (S71). The state is taken in and the state is determined (S72). If the mode fixing switch 35 instructs the fixing, the drive control unit 31 ignores the current input signal and returns to the main routine shown in FIG.
[0098]
On the other hand, if the mode fixing switch 35 is in a state in which the mode change is allowed, the drive control unit 31 switches the storage mode of the state memory 33 to the other mode (S73) and the mode after the switching. The state of the mode display light emitting element 52 of the display 50 is changed so as to correspond to (S74), and the process returns to the main routine shown in FIG.
[0099]
When a signal is input from the interlock switch 35 (Yes in S33B), the operation control unit 31 waits for the signal input to exceed a predetermined time (for example, 2 seconds) (S75), The interlock valid / invalid information in the memory 33 is switched to the other content (S76), and the state of the interlock display light emitting element 53 of the display 50 is changed so as to correspond to the content after the switch (S77). Returning to the main routine shown in FIG.
[0100]
Although the flowchart is omitted, when the operation control unit 31 detects or is notified of an error, the operation control unit 31 proceeds to an error processing routine to execute an error handling process such as a shutter stop operation or an opening operation. At the same time, a character string such as an error code or an error name is taken out from the memory in the operation control unit 31, the error display light emitting element 54 is turned on (may be blinking), and the error code or error taken out to the character display unit 51 Display the name.
[0101]
(A-3) Effects of the embodiment
According to the above-described embodiment, a user, a maintenance staff, and the like can perform a switching operation between the automatic mode and the manual mode with respect to the remote control transmitter, and the switching operation is performed by opening the entire shutter case or its inspection port. The operability can be improved.
[0102]
When switching between the automatic mode and the manual mode is performed on the remote control transmitter, it is necessary to operate two keys simultaneously for a predetermined time or longer, which is not intended by the user or maintenance personnel. Mode switching can be prevented. Here, the operation surface of the remote control transmitter has a notation for clarifying the two keys used for switching, so that it is easy for the operator to understand and an unintended operation mode switching instruction can be prevented.
[0103]
In addition, since the display is provided at a position where it can be seen from the outside at all times, the user or maintenance staff can check whether the operation mode has been switched to true without opening the entire shutter case or its inspection port. it can.
[0104]
Further, since the remote control transmitter is provided with a switching operation function between the automatic mode and the manual mode, the switching unit between the automatic mode and the manual mode is provided in the operation unit fixed to the wall surface (this is another embodiment). The position of the operator is not limited and is convenient.
[0105]
Furthermore, since the remote control transmitter is provided with a function for switching between automatic mode and manual mode, there is a possibility of operations by persons other than those permitted to switch, but a mode fixing switch is provided to switch the operation mode. Can be forcibly ignored, and unnecessary switching can be eliminated.
[0106]
In addition, when the remote control transmitter is a transmitter for switching instructions between the automatic mode and the manual mode, the remote control receiver is a receiver for switching instructions, and a transmitter and receiver dedicated to mode switching are provided ( This makes it possible to simplify the system configuration as compared to the other embodiments). Further, since the mode switching operation is the simultaneous operation of the instruction keys for the opening operation and the stopping operation, there is no need to provide a dedicated key, which also contributes to the simplification of the configuration.
[0107]
The display unit displays almost all display items necessary for maintenance, such as the status of the operation mode, so that it can be viewed from the outside at all times. The opening of the entire shutter case and its inspection opening can be almost eliminated.
[0108]
(B) Other embodiments
In the description of the above embodiment, various modified embodiments have been mentioned, but further modified embodiments as exemplified below can be given.
[0109]
(B-1) In the above embodiment, the remote controller transmitter transmits a signal instructing switching to the reverse operation mode. However, a signal directly representing the automatic mode or the manual mode is transmitted. Anyway.
[0110]
(B-2) In the above-described embodiment, the key for instructing the operation of the shutter is used to input the operation mode switching. However, a dedicated key for instructing the operation mode switching is provided to the remote control transmitter. You may make it provide.
[0111]
Even when a key for instructing the shutter operation is used, a method other than simultaneous operation of two keys may be applied to instruct switching of the operation mode. For example, the operation mode switching may be instructed by an intermittent operation pattern of the “stop operation” key (for example, operation for 2 seconds or more, non-operation within 1 second, operation for 2 seconds or more).
[0112]
(B-3) The remote control transmitter is also provided with a key (which may be a dual-purpose key) for instructing to prohibit (fix the mode) or cancel the prohibition of the operation mode. Thus, prohibition or prohibition release (permission) may be stored internally, and an operation mode switching operation in a state where prohibition is stored internally may be ignored.
[0113]
(B-4) In the above embodiment, the remote control transmitter has shown that the same ID is inserted into the frame instructing the switching of the operation mode and the frame instructing the shutter operation (such as the opening operation). , Different IDs (frame IDs for instructing switching of the operation mode may be different for each remote control transmitter or may be the same for all remote control transmitters). Similarly, the frame configuration itself may be changed.
[0114]
The remote control receiver may allow the ID allowed as a frame from the regular remote control transmitter to be different between a frame instructing switching of the operation mode and a frame instructing a shutter operation (such as an opening operation).
[0115]
In this case, in order to limit the remote control transmitter that can instruct switching of the operation mode, it may be made different. Further, the number of remote control transmitters that can instruct switching of the operation mode may be limited to one.
[0116]
(B-5) In the above embodiment, the remote control receiver gives a signal for instructing switching to the reverse operation mode to the control panel. However, the remote control receiver receives the reverse operation mode from the remote control transmitter. Even if a signal for instructing switching to is received, it may be converted into a signal directly representing the automatic mode or the manual mode and given to the control panel. In this case, the remote control receiver also needs to maintain the current operation mode.
[0117]
(B-6) In the above embodiment, the remote control transmitter and the remote control receiver communicate with each other via a wireless line. However, they may communicate with each other via a cable. Further, the terms remote control transmitter and remote control receiver in the present invention include an operation input device provided on the side of the shutter or the like and a signal receiving unit thereof.
[0118]
(B-6) In the above embodiment, the remote control transmitter and the remote control receiver each have a transmitter function for instructing switching of the operation mode and a receiver function thereof. You may make it construct | assemble a system including the exclusive transmitter and receiver which instruct | indicate.
[0119]
Even in this case, the remote control transmitter and the remote control receiver may also be used for switching the operation mode.
[0120]
(B-7) In the above embodiment, the control panel is also provided with a mode changeover switch that can instruct switching of the operation mode. However, the operation mode switching may be instructed only from the remote control transmitter. .
[0121]
(B-8) In the above embodiment, the redundant operation (long press) is also effective for the mode changeover switch of the control panel. However, for the mode changeover switch, such a redundant operation condition is used. May be eliminated.
[0122]
(B-9) Display items on the display are not limited to those in the above embodiment, and other items may be included as long as they cannot be confirmed without opening the entire shutter case or its inspection opening. .
[0123]
(B-10) In the above-described embodiment, the operation mode switching is notified through the display unit. However, other notification means such as a buzzer may be used, and other notification means are used in combination. You may do it. When using the buzzer, the sound type and the sound generation pattern may be changed depending on whether the mode is changed to the automatic mode or the manual mode.
[0124]
(B-11) Interlock validity / invalidity switching may be instructed only from the remote control transmitter as in the operation mode switching.
[0125]
(B-12) For example, with respect to a garage shutter, there is a garage shutter that is intermittently transmitted from a vehicle at a predetermined cycle, and that the signal itself performs open / close control by receiving or not receiving a signal that does not directly indicate opening / closing. (Japanese Patent Laid-Open No. 2003-125463), the switching between enabling / disabling such opening / closing control (corresponding to the automatic mode) and disabling (corresponding to the manual mode) is similar to the above embodiment. Alternatively, it may be executed by transmitting a switching signal from the remote control transmitter. The terms “auto mode” and “manual mode” in the claims are intended to include such things.
[0126]
(B-13) “Opening / closing” in the opening / closing device includes a mode in which only opening, only closing, and both opening and closing are included. The opening / closing operation direction is arbitrary, for example, the vertical direction, the horizontal direction, the inclination direction, or the like. As for the operation by the remote controller, it is only necessary to be able to perform any of the operations such as opening, closing, and stopping, and when the opening / closing body such as opening or closing operates, the movable operation range of the opening / closing body is set. It is sufficient that the operation can be performed at least in part.
[0127]
(B-14) In the above embodiments, the present invention is applied to a shutter control system. However, doors, windows, overhead doors, gates, gates (gates such as parking lots), roll screens (for example, light shielding) The present invention may be applied to a control system for an opening / closing device that generally controls the opening / closing body, such as a membrane), a blind, or an awning device.
[0128]
【The invention's effect】
According to the present invention, it is possible to instruct a user's desired operation or obtain desired information regardless of the installation location of the control panel of the opening / closing body.
