Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Industrial field of application) The present invention relates to a frontage opening / closing device such as a shutter or a blind attached to a frontage of a building.

(Prior Art) Conventionally, a front door opening / closing device such as a shutter and a blind is housed in a case whose drive device is hermetically sealed, and moreover, a relay and an electromagnetic contactor are used to perform only simple opening / closing control. Therefore, even if an abnormality occurs in the device, there is no function to notify the abnormal location or the cause of failure.

(Problems to be solved by the invention) For this reason, since the contents of the conventional door opening / closing switch such as the shutter and the blind are unknown when an abnormality occurs, the installation failure during the construction, the connection mistake, or the There is a problem that not only an inexperienced worker, such as heating the motor during the trial run, cannot take appropriate measures, but also it takes time for the measures.

Configuration of the Invention (Means for Solving Problems) In order to solve the above problems, the present invention provides a frontage opening / closing member 1 opened and closed by a motor 2 and an operation signal for driving and stopping the motor 2. Output operation circuit 17a to 17c
A plurality of detectors 7, 12 to 15 which output an abnormal signal when an abnormality is detected in the operating state of the front opening / closing member 1, the motor 2, etc., and the operation signals from the operation circuits 17a to 17c. While controlling the drive and stop of the motor 2 on the basis of each of the detectors, the detectors corresponding to the abnormal signals from the detectors 7, 12 to 15 are detected.
Control means 8 for outputting a different notification drive signal for every 7, 12 to 15
And the abnormality notification means 18 for performing different notification operation for each notification drive signal based on the notification drive signal from the control means 8.

(Operation) That is, when an abnormal signal is output from the detector that detects the occurrence of an abnormality in each of the detectors, the control unit outputs a notification drive signal corresponding to the detector that has output the abnormal signal. Then, the abnormality notification means performs a notification operation corresponding to the notification drive signal, and therefore the detector that has detected the abnormality is specified by the content of the notification operation.

(Embodiment) An embodiment in which the present invention is embodied in an electric shutter will be described below with reference to the drawings.

As shown in FIG. 1, a slat curtain 1 as a frontage opening / closing member of a shutter attached to a frontage (not shown) of a building is wound by a motor 2 via a rotation transmission mechanism 3.
It is supposed to be rewound. A rotary shaft 4 of the motor 2 is connected to a potentiometer 6 for detecting the amount of rotation of the coaxial shaft 4 via a gear train 5, and a speed detector 7 is connected to the potentiometer 6.

The speed detector 7 is connected to a central processing unit (CPU) 8 which constitutes a control means. The CPU 8 has a read-only memory (ROM) 9 storing programs, and a random access memory (RAM) 10 as a memory setting means.
Are connected.

Further, a drive circuit 11 for driving and stopping the motor 2 is connected to the CPU 8, and a temperature detector 12, an overcurrent detector 13 and an overvoltage detector 14 of the motor 2 and a slat curtain 1 are connected. The obstacle detector 15 is connected. CP
U8 identifies the detector that has output an abnormal signal among the detectors 7, 12 to 15, and outputs an alarm signal at the time interval corresponding to that detector to the abnormality notification means in the next stage to detect the abnormal point or the cause of failure. Is notified.

Further, as shown in FIG. 2, the CPU 8 is provided with a switch box as an operation unit provided with first to third operation circuits 17a to 17c.
16 are connected, and each of the circuits 17a to 17c is provided with three switches U, S, and D for respectively operating the slat curtain 1 for raising, stopping, and lowering. Then, a light emitting body (light emitting diode (hereinafter, referred to as LED) 18 in this embodiment) 18 is connected to the second operation circuit 17b provided with the stop switch S as an abnormality notifying means.

The operation circuits 17a to 17c are provided with photo couplers 19 to 22.
Are connected. When the raising switch U is operated, an operation signal U'for driving the motor 2 in the direction of raising the slat curtain 1 is output to the CPU 8 via the photo coupler 19 and the lowering switch D is operated. Then, the operation signal D'for driving the motor 2 in the direction of lowering the slat curtain 1 is changed to the photo coupler 22.
Is output to the CPU 8 via the photo coupler 20, and the operation signal S'for stopping the driving of the motor 2 is output to the CPU 8 via the photo coupler 20 when the stop switch T is operated. . Further, since the stop switch T is a normally closed switch and the light projecting elements 20a and 21a of the photo couplers 20 and 21 are always lit, the LED 18 is stopped by the stop switch S.
It always lights up except when operating.

Now, in the electric shutter configured as described above, when an abnormality occurs in its operating state and an abnormality signal is output from any one of the detectors 7, 12 to 15, CP
U8 uses the detectors that output the abnormal signal as the detectors 7, 12
The output signal is an alarm signal (notification drive signal) at a time interval corresponding to the detector. Then,
The light emitting element of the photo coupler 21 based on this alarm signal
21a is blinked, and the light receiving element 21b thereof is also turned on and off repeatedly. Therefore, the LED 18 blinks the time interval corresponding to the identified detector.

As described above, in the present embodiment, it is possible to confirm from which detector among the plurality of detectors 7, 12 to 15 the abnormal signal has been output by the blinking interval of the LED 18, so that the repair person can detect the abnormality. According to the installation location of the device, the abnormal location of the electric shutter or the cause of failure can be immediately recognized, and swift and appropriate action can be taken.

Further, since the LED 18 constituting the abnormality notifying means is connected and wired by using the second operation circuit 17b provided with the stop switch T, it is not necessary to newly install a wiring only for the LED 18. It is possible to configure an electric shutter having a monitoring function at the time of abnormality at low cost without changing the number of wires of the operation circuits 17a to 17c from the conventional one.

Although the LED 18 is used as the abnormality notifying means in the above embodiment, other lamps may be used.

Further, instead of the lamps, a sounding body that responds to an AC signal may be used to cause the CPU 8 to generate a message corresponding to the cause of the failure.

Further, in the above embodiment, the electric shutter is used, but it may be applied to a blind, an automatic door, a sliding door, a gate, or the like.

Effects of the Invention As described in detail above, according to the present invention, it is possible to confirm from which detector among a plurality of detectors the abnormal signal is output by the content of the notification operation of the abnormality notifying means, There is an excellent effect that the cause of failure can be immediately recognized and prompt and appropriate action can be taken.
