(Problems to be Solved by the Invention) According to the conventional configuration, it is convenient for the user to operate the electric blind remotely using the operating unit without having to approach the electric blind. If the blind cannot be opened or closed, there is a problem in that the actual opening/closing status of the blind, which is an opening/closing member, cannot be determined.Also, even if the blind hits an obstacle and stops, there is a problem in that the current status of the obstruction cannot be determined.

The present invention is characterized by a configuration in which a control means is provided for sending a status display signal indicating the current status of the opening/closing device to the operation unit and displaying the status on the display unit.

Further, the control means preferably outputs a signal indicating the degree of opening/closing of the electric switching device as a status display signal and causes the display means to display the signal.

Furthermore, it is preferable that the control means causes the display means to display a target opening/closing degree of the electric switching device, which is indicated by a command signal based on the operation of the operating means.

According to the control device for an electric switchgear according to claim 3, the target opening/closing degree of the electric switchgear is displayed on the display means based on the operation of the operating means of the operating section, so that it is easy to set the target opening/closing degree. At the same time, the display means serves both to display the current situation and to display the target opening/closing degree.

(Example) Hereinafter, an example in which the present invention is applied to an electric blind will be described with reference to the drawings.

First, let us describe the electric blind 1, which is an electric opening/closing device, according to FIGS. 2(a), (b) and 3. That is, in the same figure, inside a long case 2 having an opening 2a on the lower surface, there is a pipe 4 for winding up a rectangular sheet-shaped blind 3 hanging down through the opening 2a, and this pipe. A drive unit 5 is provided for rotating 4. The drive unit 5 includes a motor 6 that can rotate in forward and reverse directions, and a speed reduction mechanism 7 that transmits the rotational force of the motor 6 to the pipe 4. It has a combination of a brake device 8 connected to the rotating shaft of the motor 6 and a rotary encoder 9 for generating a position signal SP indicating the rotational position of the motor 6 (and thus the position of the blind 3). Further, within the case 2, a control circuit UNI2.]0 for controlling the operation of the drive unit 5 is provided.

As shown in FIG. 1, the control circuit unit 10 includes a microcomputer 1 as a control means, a drive circuit 12 for operating the drive unit 5 based on instructions from the microcomputer 11, and a failure detection circuit 13. It is composed of:

Furthermore, this microcomputer-1 and failure detection circuit 1
B includes the rotary encoder 9 in the drive unit 5.
The fault detection circuit 13 is further provided with ON signals from a plurality of, for example, three, obstacle detection microswitches 14 installed at the lower end of the blind 3. It has become.

Now, the operation section 15 will be described according to FIG. That is, in the figure, an operating device 17 as an operating means and a display device 18 as a display means made of an LCD are provided on the front surface of a main body case 16 having a flat rectangular shape. Further, inside the main body case 16, a microcomputer 19 serving as a control means is provided.

In this case, the operating device 17 is composed of an up (UP) switch 17a, a down (D0WN) switch 17b, and a stop (STOP) switch 1.7c, which are push button switches, and each on signal is sent by a microcomputer. It is designed to be given to 19 people. and,
When the microcomputer 19 receives a rising ON signal from the rising switch 17a, it outputs a rising operation command signal SIJ from its output terminal, and when it receives a descending ON signal from the lowering switch 17b, it outputs a lowering operation command signal from its output terminal. When SD is output and a stop ON signal is given from the stop switch 17c, a stop command signal Ss is output from the output terminal.

The display device 18 is controlled by a microcomputer 19 and is designed to display a bar graph of the target position when the blind 3 is raised or lowered. Specifically, for example, when the bar graph display is 100%, it corresponds to the upper limit position of blind 3, and when the bar graph display is 0%.
The state corresponds to the lower limit position of the blind 3.

The microcomputer 11 of the control circuit unit 10 and the microcomputer 19 of the operating section 15 are connected by a signal line 20, and specifically, this signal line 20 is one common line.

It consists of multiple communication lines and one power line.

Next, the operation of this embodiment will be explained with reference to FIGS. 5 to 8.

First, the main routine will be described according to FIG. 5. In FIG. 5, the control contents of the microcomputers 11 and 19 are shown together for convenience of explanation.

That is, when power is supplied to the electric blind 1, DC power is also supplied to the microcomputer 11, and this DC power is supplied to the microcomputer 19 via the power line of the signal line 20 and the common line. is also supplied,
With this, both microcomputers 11 and 19 start their operations. The microcomputer 19 first determines "Is there an on signal?" determination step A1, in which it determines whether an on signal for ascending, an on signal for descending, or an on signal for stopping has been given from the operating device 17. , rNOJ, this judgment step A1 is repeated.

Now, in order to raise or lower the blind 3, the user uses the raising switch 17a or the lowering switch 17.
When b is suppressed and turned on, the rising ON signal or the falling ON signal is given to the microcomputer 19. As a result, the microcomputer 19
In judgment step A1, rYEsJ is judged, and the next judgment step A2 is "Is it an on signal for stop?"
It is determined that the result is NOJ, and the subroutine A3 of "operation command signal transmission and calculation display" is entered. In this subroutine A3, the microcomputer 19 receives the rising ON signal or the falling ON signal from the rising switch 17a or the falling switch 17b, and outputs the rising operation command signal Su or the lowering operation command signal SD for the duration thereof. The blind 3 Calculate the target raising position or target lowering position corresponding to the target opening/closing degree of R.
It is stored in the AM and displayed on the display device 18.

As a result, the display device 18 increases or decreases the bar graph display while the up switch 17a or the down switch 17b is pressed. Then, when the suppressing operation of the up switch 17a or the down switch 17b is released and the bar graph display on the display device 18 stops, the stop position indicates the target up position or target down position of the blind 3.

When the ascending operation command signal Su or the descending operation command signal SD is transmitted to the microcomputer 11, the microcomputer 11 enters the "arithmetic control" subroutine A4. In this subroutine A4, the microcomputer 11 calculates the target raising position or target lowering position of the blind 3 from the duration of the raising operation command signal Su or the lowering operation command signal SD in the same way as the microcomputer 9, and stores the target position in the RAM for the target position. to be memorized. Thereafter, when the suppression operation of the ascending switch 17a or the descending switch 7b is released and the transmission of the ascending operation command signal S11 or the descending operation command signal SD is stopped, the microcomputer 1] stops the transmission (
Drive circuit 1 after a predetermined time (for example, 1 second) after reception has stopped.
2, a forward rotation drive signal or a reverse rotation drive signal is output. Therefore, when the drive circuit 12 receives a normal rotation drive signal, it drives the motor 6 in the normal rotation, and based on this, the blind 3 is wound around the pipe 4 and raised (opened). Further, when the drive circuit 12 receives a reverse drive signal, it drives the motor 6 in the reverse direction, and based on this, the blind 3 is unwound from the pipe 4 and lowered (closed). In this case, the actual raised or lowered position of the blind 3, that is, the rotational position of the motor 6, is detected by the rotary encoder 9, and the position signal S from the rotary encoder 9 is given to the microcomputer 11. , the microcomputer 11 calculates the raised or lowered position of the blind 3 from the actual rotational position of the motor 6, and stores it in the operating position RAM.
are stored sequentially. Note that while the motor 6 is being driven in forward or reverse rotation, the microcomputer 11 sends a prohibition signal to the microcomputer 19 so as not to accept any ON signal other than the ON signal for stopping the stop switch 17c. ing. Thereafter, when the blind 3 reaches the target raised position or target lowered position, the microcomputer 11 sends a forward rotation drive signal to the drive circuit 2 or The output of the reverse rotation drive signal is stopped, and thus the motor 6 is stopped and the blind 3 is stopped at the target position. Then, when the motor 6 is stopped, the microcomputer 11 goes to output step A5 of "send control end signal", and outputs the control end signal SF to connect the communication line and the common line among the signal lines 20. 9 of the operating section 15 via the microcomputer] 9 of the operation section 15.

The microcomputer] 9 of the operation unit] 5 receives the control end signal Sr, and enters the processing step A6 of "control end signal reception", and stores the target position RAM.
is cleared to stop the display on the display device 18, and the prohibition of receiving ON signals other than the ON signal from the stop switch 17c is canceled. After that, the microcomputer 19 returns to judgment step A.

When the user suppresses the stop switch 17c and gives a stop ON signal to the microcomputer 19, the microcomputer 19 judges rYEsJ at judgment step A, and then judges ``YES'' at judgment step A2. Then, the output step A7 of "stop command signal transmission" is reached, and the stop command signal S8 is transmitted to the microcomputer 1 of the control circuit unit]0.

When the microcomputer 11 of the control circuit unit]0 receives the stop command signal Ss, it goes to step A8 to determine whether the motor is being driven, and if rNOJ, it goes to processing steps A and O to detect the motor stop position. becomes.

In this case, during the subroutine A4 by the microcomputer 11 described above, when the stop command signal S5 is transmitted from the microcomputer]9 of the operation section 15,
The system jumps to step A8 for determining whether the motor is being driven, and therefore the microcomputer]
] is judged as ``YESJ'' in this judgment step A8.
"Motor stop" output step A9, drive circuit] 2
The motor 6 is stopped by stopping the output of the forward rotation drive signal or the reverse rotation drive signal to the
becomes. In this processing step A1o, the microcomputer 11 converts the current rotational position of the motor 6, that is, the current stop position of the blind 3, to the operating position J'I.
-Read from I RAM and send the next “current position signal transmission”
In output step A, the current position signal SA, which is the current situation signal, is transmitted to the microcomputer 19 of the operating section 15.

When the microcomputer 9 of the operation unit 5 receives the current position signal SA, it enters a process step A1 of "receive current position signal" and displays the current position signal SA on the display device 18. The current vertical position of the blind 3 is displayed as a bar bluff. After that, the microcomputer]9 returns to the judgment step A1. In this case, the display on the display device 18 may be stopped automatically after a certain period of time, or may be stopped by operating the stop switch 1.7C again.

The above is an explanation of the main routine for raising and lowering the blind 3. However, the microcomputer 11.19 is configured to detect abnormalities by periodic interrupts, and this will be explained according to FIGS. 6 to 8. .

That is, as shown in FIG. 6, when an interrupt for failure detection is performed, the microcomputer 1 first asks ``Is there an on signal for failure detection?'' ” judgment step B1, in which it is judged whether or not the micro switch 14 at the lower end of the blind 3 hits an obstacle and is turned on and outputs an on signal for fault detection, and when it is judged as rNOJ. Next “Is there a rotational abnormality?
” is the judgment step B2.

In this judgment step B2, the microcomputer 11 detects whether or not there is an abnormal rotation in the motor 6.
Specifically, the position signal SP from the rotary encoder 9
That is, pulses are counted every unit time, and if this is smaller than a set value, that is, if the number of revolutions of the motor 6 is lower than the set number, it is determined that the rotation is abnormal. Then, when the microcomputer 11 determines rNOJ in this determination step B2, it proceeds to a determination step B3 of "Is it in a malfunction state?", and here it is determined whether the electric blind 1 is in a malfunction or in an abnormal rotation failure. If there is no failure condition, the system returns to the main routine.

If the lower end of the blind 3 hits an obstacle during its lowering operation, the microswitch 14 turns on and outputs an on-signal for fault detection, so the microcomputer 11
is determined to be rYESJ at determination step B+, and the next "motor stop" output step B4 occurs, the motor 6 is stopped for -10 seconds, and then the motor 6 is driven in forward rotation slightly to raise the blind 3 slightly. make it stop. Therefore, the microswitch]4 is turned off and stops outputting the on signal.

The microcomputer 1] performs the next processing step B5 of "Accepting operation command signals is prohibited", and here, the microcomputer 1
The rising operation command signal S from the microcomputer 19 of 5
Even if u or lowering operation command signal SD is sent,
Please do not accept this. Specifically, these signals Su and S are received, but the motor 6 is not controlled accordingly. [Microcomputer]] further performs an output step B6 of "failure detection signal transmission".
Here, the fault detection signal sB is transmitted to the microcomputer 19 as a current status signal. When the microcomputer] 9 receives the fault detection signal sn, it goes to the "failure mode memory" processing step B7,
Here, a signal indicating the "failure mode" is stored in the RAM. Incidentally, in the microcomputer 11 as well, such signals are stored in the RAM. After that, the microcomputer 1 performs the next output step B8 of "display device blinking", in which the bottom bar of the display device 8 is displayed blinking, thereby notifying that a failure has occurred. . Then, one microcomputer returns to the main routine.

After that, when an interrupt for failure detection is performed, the microcomputer 11 performs judgment steps B1 and B2.
Both of them are judged to be rNOJ and the process goes to judgment step B3. However, in this judgment step B3, since the F failure mode is set at this time, it is judged to be rYEsJ and the process goes to judgment step B3.
Is there a problem? ” judgment step B. Then, in this judgment step B, the microcomputer 11 selects rYE.
It is determined that sJ (failure/failure) has occurred, and the process moves to the next subroutine BIO of "search for clearing one fault." This Zabrutin B
IO will be described later.

On the other hand, when an abnormality occurs in the rotation of the motor 6], the microcomputer 11 determines rYEsJ in determination step B2 and outputs "motor stop" in step B.
l+, and the motor 6 is stopped.

As a result, abnormal rotation of the motor 6 can be detected without any trouble. The microcomputer 11 then goes through a processing step B1□ similar to the processing step B5 described above, and reaches an output step B13 of "send abnormality detection signal", and sends the abnormality detection signal SC to the microcomputer 19 as a current status signal.
Send. In the microcomputer 19, an abnormality detection signal S is generated.

, processing step B1 of "abnormal mode storage" is received.
4, and here the signal indicating "abnormal mode" is RA
Let M memorize it. Incidentally, in the microcomputer 11 as well, such signals are stored in the RAM. After that, the microcomputer 19 performs the next "display device blinking" output step B15, in which the display device 18
For example, the topmost bar is displayed blinking to notify that an abnormal rotation failure has occurred. The microcomputer 19 then returns to the main routine. After that,
When a failure detection interrupt is performed, the microcomputer 11 determines rNOJ in both decision steps B and B2.
At this judgment step B3, since the "abnormal mode" is set at this time, it is determined that it is rYEsJ, and the process goes to judgment step B, which asks "Is it a failure?". And microcomputer 1
1, in this judgment step B, it is judged as rNOJ (abnormal rotation failure) and the process moves to the next "abnormality cancellation search" subroutine B16. This subroutine B16 will be described later.

Next, the subroutine BIO of "fault removal search" will be described with reference to FIG. The microcomputer 11 is
Step B 101 determines whether there is a command signal, and if rNOJ, the process returns to the main routine. That is, the microcomputer 11 raises the lift switch 17a after the user removes the obstacle.

It waits until the down switch 17b or the stop switch 17c is depressed. Then, when the user removes the obstacle and presses any of the switches 17a to 17c, the microcomputer 11 performs the judgment step B.
lot is determined to be rYESJ, and the process proceeds to step B 102 of "failure mode release", where the memory of the "failure mode" in the RAM of the microcomputer 11.19 is cleared. This allows the microcomputer 11 to perform control based on each signal SLI+SD and B5.

The microcomputer 11 then proceeds to judgment step B 103 of "Is it a rising operation command signal?", and here rY
When it is determined that Esl is the output step Bl (14) of "display device increase drive", the bar display at the bottom row of the display device 18 is switched to continuous lighting via the microcomputer 19, and the ascending operation command signal S is continued. The bar graph display is increased by the amount of time.Then, the microcomputer 11 outputs the "motor drive" output step BI.
05, and one second after the raising operation command signal Sll stops, the motor 6 is driven to rotate in the forward direction to raise the blind 3 to the target raised position. If the microcomputer]1 determines rNOJ in the determination step 8103, it goes to the determination step B106 of "Is it a stop command signal?", and if it determines rYEsJ here, it goes to the output step of "motor stop position display". BI07, and the microcomputer 19 causes the display device 18 to display the current rotational position of the motor 6, that is, the current vertical position of the blind 3. Then, the microcomputer 11 determines rNOJ (a descending operation command signal) in judgment step B106.
When it is determined that this is the case, output step B 108 of "display device blinking stop" occurs, and here the bar display at the bottom of the display device 18 is changed to continuous lighting. After that, the microcomputer 11 outputs "motor drive" step B10.
9, the motor 6 is driven in reverse to lower the blind 3 to the first target lowering position.

Now, the subroutine B16 of "abnormality cancellation search" will be described with reference to FIG. The microcomputer 11 is
A determination step B161 is made as to "Is there a stop command signal?", and if "NO", the process returns to the main routine. The microcomputer 11 performs this judgment step B161.
If it is determined to be YESJ, the process proceeds to step BI62 of "abnormal mode release", where the memory of "abnormal mode" in the RAM of the microcomputer 1119 is released.

Thereafter, the microcomputer 11 outputs "motor stop position display" in step B. 3, display device 18
displays the current position of blind '3.

According to this embodiment, the following effects can be obtained.

That is, up switch 1.7 a or down switch 1
When setting the blind 3 to the target raised position or target lowered position by suppressing 7b, the position is displayed on the display device]
8 is displayed in a herb rough manner, it is easy to set the target position. And microcomputer 11
The motor 6 is rotated forward or reversed and automatically stopped when the blind 3 reaches the target position, which is extremely convenient for use.In this case, the target position is displayed on the display device 18 Since the display is stopped, the display device 18 is not made to perform unnecessary display for a long period of time. When the stop switch 17C, which is the display operation means of the operating device] 7, is suppressed, the display device 18 displays the current stop position of the blind 3, which is the current status of the electric blind 1. Even if the blind 1 is hidden behind something and cannot be seen directly, the user can reliably know the elevation position corresponding to the current degree of opening/closing of the blind 3 by looking at the display device 18.

Furthermore, in the event that the lower end of the blind 3 hits an obstacle during the lowering operation and a malfunction occurs, the microcomputer 11 detects this and causes the bottom bar of the display device 18 to blink. is the display device 18
By looking at this, it is possible to know that the current status of the electric blind 1 is a failure, and appropriate measures such as removing the obstruction can be quickly taken.

Furthermore, when the rotation of the motor 6 is abnormally low, the microcomputer 11 detects this and causes the bar at the top of the display 8 to blink. By knowing that the current condition of the electric blind 1 is that the motor 6 is malfunctioning due to abnormal rotation, appropriate measures such as immediately stopping the motor 6 can be quickly taken.

Since a single display device 18 is configured to display the target position, current stop position, fault failure display, and abnormal rotation failure display in a manner that allows them to be distinguished from each other, a display device is provided for each display. Compared to the case, the configuration is simpler (1i) and can be done at a lower cost.

In the first embodiment, the stop switch] and 7c are also used as the display operation means, but a specific display operation switch may be provided separately from this.

Further, in the above embodiment, the signal line 20 is used for transmission and reception between one microcomputer and the other microcomputer 1, but instead, radio waves can be used.

Wireless remote control using airborne signals such as infrared rays may also be used.

Furthermore, in the above embodiment, two microcomputers]11 are provided as the control means, or only one of them may be provided.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, and may be implemented with appropriate modifications within the scope of the invention, such as being applicable not only to electric blinds but also to electric shutters. Of course.

[Effects of the Invention] Since the present invention is as explained below, it has the following effects.

According to the control device for an electric switchgear according to claim 1, the current status of the electric switchgear is displayed on the display means of the operation section, so that even when the electric switchgear is hidden behind something and cannot be seen directly, The user can reliably know the current status of the electric switchgear by looking at the display means.

According to the control device for an electric switchgear according to claim 2, since the display means particularly displays the degree of opening/closing as the current status of the electric switchgear, the user can see the electric switchgear without looking directly at it. It is possible to know with certainty the degree of opening and closing.

According to the control device for an electric switchgear according to claim 3, since the display means displays the target opening/closing degree of the electric switchgear, it becomes easy to set the target opening/closing degree, and the display means can display the target opening/closing degree. Since both the current situation and the current situation are displayed, the configuration becomes simpler.
