FIG. 9 is a flowchart of each switch input process from the controller 3. FIG. Next, the operation of the embodiment of the present invention will be described with reference to FIGS.

  First, in step S1 (abbreviated as S1 in the drawing), an ON signal from each switch of the controller 3 is read, and an input switch value is acquired. In step S2, it is determined whether or not all the input switch signals are off signals (hereinafter referred to as “no” as the input switch value).

  Here, since all the input signals at the normal time when the switch operation is not performed are all “OFF” of the OFF signal, “YES” in step S2, “NO” when any switch operation is not performed “NO”. If it is “none”, the control stage management timer (provided in the RAM of the microcomputer 70) is incremented by “+1” in step S3. If it is not “none”, the control stage management is performed in step S4. The timer is reset to “0”.

  The period of the main routine is managed separately in the management process so as to be 10 milliseconds (an example value, which may be another 15 milliseconds). That is, the control stage management timer during a period when some switch operation is performed is held at “0”, and when the switch operation is not performed and becomes “None”, the control stage management timer is “+1” every 10 milliseconds and is 10 seconds. Later it will be “1000”.

  In the next step S5, it is determined whether or not the control stage management timer value is 10 seconds or longer. When the control stage management timer value is 10 seconds or longer, the control stage during the opening / closing operation is “upper” or “ Set to “Lower”. That is, when the input value of the normal stage setting switch 181 is “lower” in step S6, the control stage is set to the lower stage in step S7, and when the input value is “upper stage”, the control stage is set to the upper stage in step S8. The When the control stage management timer value is less than 10 seconds, the current value is held since the set value of the control stage is not changed.

  Next, the input switch value is determined in step S11 of FIG. The types of determination are “up” (switch 61), “stop” (switch 62), “down” (switch 63), “FOR” (switch 64), “REV” (switch 65), and “ “Stop + FOR” (switches 62 and 64), “Stop + REV” (switches 62 and 65), and “Others” in other cases. “Other” includes the case of “None” described above (all are OFF signals).

  Then, in the next steps S12 to S19 for each input switch value, the old input switch value that is the input switch value in the previous main routine is determined. Here, since the input switch value and the old input switch value are “None” at the normal time when the switch operation is not performed, “Other” is determined in Step S11, and “Other than FOR, REV” is also determined in the next Step S19. In the next step S29, the old input switch value is merely updated from “None” to “None” with no substantial change, and this processing is repeated until an ON signal is input from the controller 3. It becomes. Further, by processing the main routine every 10 milliseconds, it is determined that there is “none” in step S2, and the control stage management timer is continuously “+1” in step S3. In step S6, the set value of the normal stage setting switch is determined, and in the next step S7 or S8, the control stage is continuously set as set by the normal stage setting switch.

  Next, as a case where the controller 3 is operated by a switch, an operation when the FOR switch 64 which is an opening / closing operation is first operated will be described. It is assumed that the normal stage setting switch 181 is set to “lower stage”.

  When the FOR switch 64 is operated and an ON signal is input to the microcomputer 70, the input switch value “FOR” is acquired in step S1, and it is determined in step S2 that it is not “no”, and the control in step S4 is performed. The stage management timer “0” process is executed, the control stage management timer value becomes “0”, the timer value is determined to be “less than 10 seconds” in the next step S5, and the control by the normal stage setting switch 181 in steps S6 to S8. Since the stage setting process is not performed, the current value is held in the control stage.

Since the normal stage setting switch 181 is normally set as described above, “lower stage” is held. In step S11, the input switch “FOR” is determined. In the next step S14, the old input switch is determined as “none”. In step S20, the control stage is determined as “lower” as described above, and the process proceeds to step S26. Thus, the first motor 4 is set to rotate forward. As the first motor 4 rotates forward, the lower slat 91 rotates in the clockwise direction.
As described below, the forward rotation of the first motor 4 is continued until the FOR switch 64 is not pressed down. In step 29, the old input switch value is updated from “none” to “FOR”. Then, in the next main routine, the input switch value “FOR” is acquired in step S1 in the same manner as described above, and it is determined in step S2 that it is not “no”, and the control stage management timer “0” processing in step S4 is performed. In the next step S5, it is determined that the timer value is "less than 10 seconds", and the current value is held in the control stage. In step S11, “FOR” is determined. In the next step S14, since the old input switch value is “FOR”, it is determined as “other than none”, and in step S29, “FOR” is substantially determined. It is only updated to “FOR” with no change, and this is repeated.

  Next, when the FOR switch 64 is depressed from depressing, the switch input value “none” is acquired in step S1, and “no” is determined in step S2, and the control stage management timer “+1” processing in step S3 is performed. And the control stage management timer value is changed from “0” to “1”. In step S11, it is determined as “none”, that is, “other”. In step S19, since the old input switch value is “FOR”, it is determined as “FOR or REV”. In step S28, the first motor 4 is determined. Then, the second motor 13 is stopped and set, the first motor 4 which has been rotating forward is stopped, and the rotation of the lower slat 91 is stopped. In step S29, the old input switch value is updated from “FOR” to “None”.

  In the next main routine, the input switch value “none” is acquired in step S1 in the same manner as described above, and “no” is determined in the next step S2, and the control stage management timer “+1” processing (step S3). And the control stage management timer value is changed from “1” to “2”. In the next step S5, it is determined that the timer value is "less than 10 seconds", and the control stage is held at the current value, that is, "lower stage". In step S11, “None”, that is, “other” is determined. In the next step S19, since the old input switch value is “none”, it is determined as “other than FOR and REV”, and in step S29. It is only updated from “no” to “no” with no substantial change.

  Then, this process is repeated. When the timer value becomes “1000” by the control stage management timer “+1” process in step S3 and becomes 10 seconds or more, it is determined as “10 seconds or more” in step S5. Is updated to the setting stage of the normal stage setting switch 181. That is, in step S6, the setting of the normal stage setting switch 181 is determined to be “lower stage”, and the control stage is updated to “lower stage” in step S7. In addition, since it is a “lower stage” before the update, there is no substantial change.

  Similarly, when the REV switch 65 is operated, the processing is performed in the same manner as when the above-described FOR switch 64 is operated. However, the input switch value “REV” is determined in step S11, and the process proceeds to step S15. Thus, the old input switch value is determined to be “none”, the setting of the normal stage setting switch 181 is determined to be “lower” in step S21, the first motor 4 is inverted and set in step S27, and the lower slat 91 is It rotates in the counterclockwise direction opposite to that when the FOR switch 64 is operated.

  When the REV switch 65 is changed from being pressed to not pressed, it is determined that the input switch value is “none”, that is, “other” in step S11, and the old input switch value is “REV” in step S19. "FOR or REV" is determined, the motor stop setting process of step S28 is performed, the first motor 4 that has been reversed is stopped, and the rotation of the lower slat 91 is stopped.

Next, the control stage switching operation will be described.
When the stop switch 62 is operated and an ON signal is input to the microcomputer 70, the control stage management process described above is performed, and after the control stage management timer is set to “0” (step S4), the control stage input is input in step S11. The switch value is “stopped”, and the old input switch value is determined to be “none” in step S18, and the first motor 4 and the second motor 13 are stopped and set in step S28.

  That is, when the first motor 4 and the second motor 13 are stopped, the stop is maintained. Note that, as described above, the operation is stopped. In step S29, the old input switch value is updated from “none” to “stop”. In the next and subsequent main routines, since the old input switch value is “stopped” in step S18, it is determined that “other than none, up, down, FOR, REV” and the old input switch value is updated in step S29. It is only updated from “stop” to “stop” with no substantial change.

  In this state, that is, in the state where the ON signal of the stop switch 62 is input, when the “FOR” switch 64 is operated next and the ON signal is input to the microcomputer 70, the “stop + FOR” input switch in step S 1. After the value is acquired and the control stage management timer is set to “0” in step S4 as described above, the input switch value “stop + FOR” is determined in step S11, and the old input switch value “stop” is determined in step S12. In step S22, the control stage is switched to “upper stage”.

  In step S29, the old input switch is updated from “stop” to “stop + FOR”. Similarly to the above, in the next and subsequent main routines, it is determined in step S12 that “other than stop, nothing”, and the old input switch value continues to hold “stop + FOR”. Further, since the control stage management timer value also keeps “0”, the control stage also keeps the “upper stage” of the set value that is the current value.

  Next, when the stop switch 62 and the “FOR” switch 64 that are being pressed are not pressed simultaneously, “No” is acquired in Step S1, and “No” is determined in Step S2, and the control stage management timer “+1” is determined. ”(Step S3), the control stage management timer is changed from“ 0 ”to“ 1 ”, but it is determined that it is less than 10 seconds (step S5), and the control stage value is kept at the current value, that is,“ upper stage ”.

  In step S11, “no”, that is, “other”, and in step S19, the old input switch value is “stop + FOR”, so it is determined as “other than FOR and REV”, and in step S29, the old input switch value is “stop + FOR”. The input switch value is updated to “None”.

  At the next main routine, the control stage management timer is changed from “1” to “2” in step S3 in the same manner as described above. In step S19, the old input switch value is “none”, so “other than FOR and REV”. In step S29, the old input switch value is updated from “none” to “none” with no substantial change. In the subsequent main routine, the control stage management timer is only incremented by "+1" in step S3, but the 10 seconds until it reaches "10000" is determined to be less than 10 seconds in step S5. The switching process of the control stage according to the setting of the setting switch 181 is not performed, and the current control stage, that is, the “upper stage” is held.

  However, if it is 10 seconds or longer, it is determined in step S5 that it is 10 seconds or longer, and the control stage is switched to the “lower stage” set by the normal stage setting switch 181.

  In the above-described control stage switching operation, the case where the stop switch 62 is first pressed and then the FOR switch 64 is pressed has been described. However, when the switch is simultaneously pressed, the input switch value “stop + FOR” is set in step S11. After the determination, it is determined in step S22 that the old input switch value is “none”, and similarly, the “upper stage” control stage switching process in step S22 is performed.

  However, if the stop switch 62 is pressed after the FOR switch 64 is pressed, the old input switch value is “FOR” in step S29. Therefore, the stop switch 62 is pressed later and the process proceeds to step S11. Even if it is determined as “stop + FOR”, since the old input switch value is “FOR” in the next step S22, it is determined as “other than stop, no”, and the control stage switching process in step S22 is not performed.

  In the above-described control stage switching operation, the order of pressing to non-pressing has been described. However, when the FOR switch 64 is not pressed, the input switch value determination in step S11 first determines “stop”. In the next step S18, since it is the old input switch value “stop + FOR”, it is determined as “other than none, ascending, descending, FOR, REV”, and the old input switch value update in step S29 (from “stop + FOR” to “stop”). When the stop switch 62 is not pressed down, the input switch value is determined to be “None”, that is, “Other”, and the old input switch value is “Stop” in the next Step S19. Is determined as “other than FOR and REV” and only the old input switch value update (from “stop” to “no”) in step S29 is performed. The same result as in the case where the non-depressed simultaneously above.

  However, when the reverse stop switch 62 is not pressed, the input switch value determination in step S11 is first determined as “FOR”, and in the next step S14, the old input switch value is “stop + FOR”. If it is determined as “other than none” and only the process of updating the old input switch value (from “stop + FOR” to “FOR”) in step S29 is performed, and the FOR switch 64 is also not pressed, the input switch value determination in step S11 is “no”. In other words, since the old input switch value is “FOR” in the next step S19, it is determined as “FOR or REV”, and the old input switch is updated (“NO” from “FOR” in step S29). Before step F), the stop set of the first motor and the second motor in step S28 is performed. However, since neither the first motor nor the second motor is operating, only redundant processing is performed.

  Next, the operation of another control stage switching operation will be described. After the above-described stop switch 62 is pressed, in that state, that is, in a state where the on signal of the stop switch 62 is input, when the “REV” switch 65 is operated next and the on signal is input to the microcomputer 70, In step S1, the “stop + REV” input switch value is acquired, and as described above, the control stage management timer “0” is set in step S4. Then, in step S11, the input switch value “stop + REV” is set, and in step S12. It is determined that the old input switch value is “stop”, and the control stage is switched to “lower stage” in step S23.

  In step S29, the old input switch is updated from “stop” to “stop + REV”. In the same manner as described above, in the next and subsequent main routines, it is determined in step S12 that it is “other than stop, nothing”, and the old input switch value is also kept at “stop + REV”. Since the control stage management timer value is also kept at “0”, the control stage is kept at the “lower stage” which is the current value.

  Next, when the pressed stop switch 62 and “REV” switch 65 are not pressed at the same time, “No” is acquired in Step S1, and “No” is determined in Step S2, and the control stage management timer “+1” is determined. ”(Step S3), the control stage management timer is changed from“ 0 ”to“ 1 ”, but it is determined that it is less than 10 seconds (step S5), and the control stage value is kept at the current value, that is,“ lower stage ”.

  In step S11, “no”, that is, “other”, and in step S19, the old input switch value is “stop + REV”, so it is determined as “other than FOR and REV”. In step S29, the old input switch value is “stop + REV”. The input switch value is updated to “None”. At the next main routine, the control stage management timer is changed from “1” to “2” in step S3 in the same manner as described above. In step S19, the old input switch value is “none”, so “other than FOR and REV”. In step S29, the old input switch value is updated from “none” to “none” with no substantial change.

  In the subsequent main routine, the control stage management timer is only incremented by "+1" in step S3, but the 10 seconds until it reaches "10000" is determined to be less than 10 seconds in step S5. The switching process of the control stage according to the setting of the setting switch 181 is not performed, and the current control stage, that is, the “lower stage” is held. However, if it is 10 seconds or more, it is determined in step S5 that it is 10 seconds or more, and the control stage is switched to the setting of the normal stage setting switch 181, that is, “lower stage”.

  In this case, the update is performed without substantial change from “lower” to “lower”. However, when the setting of the normal setting switch 181 is on the “upper” side, the switch operation is not performed at normal time. In steps S6 to S8, since the control stage is held in the “upper stage” of the setting of the normal stage setting switch 181, the switching is updated from “upper stage” to “lower stage”.

  Note that the difference between the pressing order of the stop switch 62 and the REV switch 65 and the order from pressing to non-pressing is the same as the above-described “upper” control stage switching operation, so the description is omitted. In step S23, the “lower stage” control stage switching process is performed. However, if the stop switch 62 is depressed after the REV switch 65 is depressed, the “lower stage” control stage switching process in step S23 is not performed.

  In addition, when the REV switch 65 is not pressed down, only the old input switch value is updated (step S29). However, when the stop switch 62 is not pressed down, the first motor 4 in step S28 and the redundant operation are performed. Stop setting processing of the second motor 13 is performed.

  When the control stage switching operation described above is performed, as described above, the control stage holds the switched value for 10 seconds. When the above-described opening / closing operation, that is, the FOR switch 64 or the REV switch 65 is operated during the 10 seconds, the control stage is usually determined as “lower stage” in step S20 or S21 as described above. If the control stage switching operation is performed within 10 seconds, it is determined that the control stage is “upper stage”.

And, unlike the time of the above-described opening and closing operation, when the second motor 13 and the second motor 13 is rotated forward set during FOR switch 64 operated in the step S24 is rotated forward, the upper slat 9 2 rotates clockwise When the FOR switch 64 is not depressed, it is determined as “none”, that is, “other” in step S11, and in the next step S19, it is determined as “FOR or REV” because the old input switch value is “FOR”. rotation of the upper slat 9 2 is stopped by the second motor 13 is stopped at the stop processing of step S28 Te.

  Up to now, the setting of the normal stage setting switch 181 has been described as “lower stage”. However, when the setting is “upper stage”, the above-described normal opening / closing operation is “lower stage”, whereas In steps S6 to S8, the control stage is held at the “upper stage” of the setting of the normal stage setting switch 181. Therefore, in step S20 or S21, the control stage is determined to be “upper stage” and the same as described above by step S24 or S25. Opening / closing operation of the “upper stage”.

  In addition, when the opening / closing operation, that is, the FOR switch 64 or the REV switch 65 is operated within 10 seconds after the above-described “lower” control stage switching operation is performed, the control stage is determined to be the “lower stage” in step S20 or S21. By step S26 or S27, the same “lower” opening / closing operation as described above is performed.

  In addition, when the opening / closing operation is performed within 10 seconds after the control stage switching operation, the control stage management timer is reset to “0” in step S4, so that the control switched for 10 seconds after the opening / closing operation is performed. The steps are retained. Therefore, the opening / closing operation in the subsequent switched control stage can be performed within 10 seconds.

  As described above, the “multiple operation” in the present invention is an operation state in which operation periods of two or more operation units are at least partially overlapped, and operation periods of two or more operation units are not necessarily from the beginning. There is no need to duplicate all the way to the end.

Next, the lifting operation will be described.
When the up switch 61 is operated and an ON signal is input to the microcomputer 70, the input switch value “rise” is acquired in step S1, and it is determined in step S2 that it is not “no”, and the control in step S4 is performed. The stage management timer “0” process is executed, the control stage management timer value becomes “0”, the timer value is determined to be “less than 10 seconds” in the next step S5, and the control by the normal stage setting switch 181 in steps S6 to S8. Since the stage setting process is not performed, the current level “lower stage” is held in the control stage.

  Then, in step S11, it is determined that the input switch is “up”, and in the next step S16, it is determined that the old input switch is “none”, and in step S26, the first motor is set to rotate forward. Thereby, the raising / lowering shaft 5 and the winding drum 31 rotate integrally, the lifting tape 11 is wound up, and a blind goes up. In step 29, the old input switch value is updated from “none” to “rise”.

  Then, in the next main routine, the input switch value “increase” is acquired in step S1 in the same manner as described above, and it is determined in step S2 that it is not “no”, and the control stage management timer “0” process in step S4 is performed. In the next step S5, it is determined that the timer value is "less than 10 seconds", and the current value is held in the control stage.

  Then, in step S11, it is determined as “rising”, but in the next step S16, it is determined that the old input switch is “other than none”, and in step S29, “rising” is updated to “rising” with no substantial change. This will be repeated, and the ascending operation will continue.

  Next, when the ascending switch 61 is pressed from the pressed state to the non-pressed state, the switch input value “none” is acquired in step S1, “no” is determined in step S2, and the control stage management timer “+1” process in step S3 is performed. And the control stage management timer value is changed from “0” to “1”. In step S11, it is determined that there is “none”, that is, “other”. In step S19, since the old input switch value is “increase”, it is determined that “other than FOR and REV”. In step S29, the old input switch is determined. The value is updated from “increased” to “none”.

  At the next main routine, the control stage management timer value is changed from “1” to “2” by the control stage management timer “+1” in step S3, and the old input switch value is “none” in step S19. Therefore, it is determined that “other than FOR and REV”, and in step S29, the old input switch is updated from “no” to “no” with no substantial change, and the next controller 3 is operated to input an ON signal. The above processing is repeated until it is done. That is, the control stage management timer value is only incremented by “+1” every 10 milliseconds in step S3.

  Next, when the stop switch 62 is operated and an ON signal is input to the microcomputer 70, the control stage management process described above is performed, and after the control stage management timer is set to "0" (step S4), the step It is determined that the input switch value is “stop” in S11 and the old input switch value is “none” in step S18, and the first motor 4 and the second motor 13 are stopped and set in step S28. The first motor 4 that has been stopped stops, and the above-described ascending operation stops.

  In step 29, the old input switch value is updated from “none” to “stop”. In the next main routine, the control stage management process is followed by “stop” in step S11. In the next step S18, since the old input switch value is “stop”, the old input switch “none” is determined. It is discriminated as “other than” and only “stop” is updated from “stop” to “stop” without substantial change in step S29, and this is repeated.

  Next, when the stop switch 62 is pressed from the pressed state to the non-pressed state, the control stage management process switches to the control stage management timer “+1” process, but the input switch process is determined as “none”, that is, “others” in step S11. In step S19, since the old input value is “stop”, it is determined as “other than FOR and REV”, and in step S29, the old input value is updated from “stop” to “none”. Similarly, in the subsequent main routine, the control stage management timer value is incremented by the control stage management timer “+1” in step S3, and the old input switch value is “none” in step S19. Until the old input switch is updated from “None” to “None” with no substantial change in Step S29 until the next controller 3 is operated and an ON signal is input, it is determined that “other than FOR, REV”. The process will be repeated.

  Similarly, when the down switch 63 is operated, the process is performed in the same manner as when the above-described up switch 61 is operated. However, in step S11, it is determined that the input switch value is “down” and the process proceeds to step S17. Thus, it is determined that the old input switch value is “none”, and the first motor is reversed and set in step S27.

  Thereby, the raising / lowering shaft 5 and the winding drum 31 rotate integrally, the lifting tape 11 is wound down, and a blind falls. Then, when the lowering switch 63 is changed from being pressed to not pressed, and when the stop switch 62 is pressed, the processing is the same as in the case of the above-described raising switch 61, and thus the description thereof is omitted.

  In the above-described embodiment, the control stage is distinguished only during the opening / closing operation, and the raising / lowering operation is not distinguished, but the control stage value managed also during the raising / lowering operation is adopted to perform the detailed raising / lowering operation. For example, a user-friendly electric blind can be obtained.

  Specifically, the ascending / descending range is limited to the controlled range of the control stage. For example, when the ascending operation is performed when the control stage is “lower stage”, the upper limit position of the lower stage, that is, the upper stage The microcomputer 70 forcibly stops the ascending operation at the lower limit position.

  And when it wants to raise to the upper stage side, a control stage is switched to an "upper stage" by control stage switching operation, and ascending operation is performed. Similarly, the lowering operation is forcibly stopped at the lower limit position of the upper stage, that is, the upper limit position of the lower stage when the reverse control stage is “upper stage”. Then, when it is desired to descend to the lower stage side, the control stage is switched to “lower stage” by the control stage switching operation and the lowering operation is performed. Furthermore, a change-over switch may be provided so that the entire range of the upper stage and the lower stage can be moved up and down as in the above-described embodiment.

  In addition, although the normal stage setting switch 181 is included in the control board 18, it may be easily switched by attaching it to the head box 1 or the like.

  In addition, control stage management is not on the controller but on the main unit side, but when operating using communication lines to multiple blinds, operation communication including control stage data (upper / lower / all stages) It is better to have control stage management on the controller side as a signal. In this case, in consideration of compatibility with a blind having one general group, an operation communication signal having no control stage data may be processed so as to be set to the normal stage setting switch 181. . Further, the normal stage setting switch 181 may be switched by an operation communication signal.

  Further, the above-described normal stage setting switch 181 may not be provided, and the lower group may be selected and designated as a control target whenever a specific time (10 seconds) has elapsed after the control stage switching operation.

  When the above-described normal stage setting switch 181 is used to input an angle adjustment operation signal by an angle adjustment operation after the operation signal from the non-dividing electric blind operation means is not input for a specific time to the control means, An input setting unit is configured to input and set which of the lower group is to be controlled. As described above with reference to FIG. 8, the control means performs input setting when an angle adjustment operation signal is input by an angle adjustment operation after the operation signal from the non-dividing electric blind operation means is not input for a specific time. The group whose input is set by the means is the control target. The above-described S11, S12, and S13 constitute non-split type electric blind operating means that does not have an operation unit dedicated to group designation for designating either the upper group or the lower group and adjusting the blade angle. Has been. Based on the operation signal output from the non-divided electric blind operating means, the plurality of operation units provided in the non-divided electric blind operating means are operated in duplicate by S11, S12, and S13 described above. Multiple operation mode discrimination means for discriminating the operation mode of multiple operations to be performed is configured. The above-described S22 and S23 constitute a control target selection unit that selects either the first angle change unit or the second angle change unit as a control target according to the determination result by the multiple operation mode determination unit.

  In the above-described embodiment, the first electric motor that is used for both the lifting operation and the opening / closing operation is used for adjusting the angle of the lower blade, and the second motor that performs only the opening / closing operation is used for adjusting the angle of the upper blade. Used for use. However, the present invention is not limited to this, and the first electric motor that is used for both the lifting operation and the opening / closing operation is used for adjusting the angle of the upper blade, and the second electric motor that performs only the opening / closing operation is used for adjusting the angle of the lower blade.
