Embodiments of the present invention will be described below with reference to the drawings. The electric shutter device according to the present invention is characterized in that the means for turning on or blinking the lamp of the reception monitor unit is improved.
The same reference numerals are given to other members common to the conventional products,
A detailed description thereof will be omitted. <First Embodiment> A first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a schematic configuration of an example of an electric shutter device suitably used in the first embodiment of the present invention. 1 differs from the conventional electric shutter device shown in FIG. 4 in that a discrimination display means 13 is provided between the control unit 7 and the reception monitor 11. As described above, the radio wave environment at the installation position of the transmitter / receiver may be a place where the transmission / reception environment is poor due to noise (abnormal signal), that is, disturbance light such as interfering radio waves, light, ultrasonic waves, or noise.

Now, when the receiver 10 is receiving these noises, the lamp 12 of the reception monitor unit 11 is lit in some cases, and when the obstacle sensor 8 detects an obstacle, the transmitter 9 transmits the noise. It may not be possible to clearly identify that the signal is not a normal signal to be transmitted. Therefore, in the present embodiment, the determination display means 13 always determines whether or not the receiver 10 is receiving noise. That is, the shutter curtain 1 by the input operation of the switch unit 2
When the obstacle sensor 8 detects an obstacle during the downward movement, the transmitter 9 transmits an optical signal to a receiver 10 provided at a position opposite to the transmitter 9. The receiver 10 converts this optical signal into a predetermined control signal which is set in advance and transmits the control signal to the control unit 7. In response to this, the control unit 7 stops the winding shaft 4 by the opening / closing device 3 to stop the shutter curtain 1, and the discrimination display unit 13 lights the lamp 12 of the reception monitor unit 11 for a predetermined time (for example, 2 seconds). .

On the other hand, the receiver 1 is affected by noise.
0 is converted to a signal other than the predetermined control signal, and
, The discrimination display means 13 causes the lamp 12 to blink at a predetermined blinking interval (for example, 0.3 seconds on, 0.2 seconds off).
To blink. In this case, the control unit 7 does not issue a command to stop the opening and closing of the shutter curtain 1 to the switchgear 3. As a result, when noise is received, the lamp blinks, and a different notification is made than when the lamp is turned on for a predetermined time based on the reception of a signal from the transmitter 9, so that the receiver 10 It will be possible to identify whether it is being received.

<Second Embodiment> A second embodiment of the present invention will be described with reference to the drawings. FIG. 2 is a flowchart illustrating an example of the operation of the electric shutter device according to the second embodiment of the present invention. The configuration of the electric shutter device according to this embodiment is the same as that described in the first embodiment shown in FIG. 1, and the same members are denoted by the same reference numerals, and detailed description thereof will be omitted. This embodiment differs from the first embodiment in that when the receiver 10 receives noise, the lamp 12 of the reception monitor unit 11 blinks, and the blinking interval of the lamp 12 is determined by the noise reception frequency. Is divided into a plurality of stages. When the obstacle sensor 8 detects an obstacle, the transmitter 9
When the receiver 10 receives the optical signal transmitted from the
Also in this embodiment, the electric shutter device operates in the same manner as in the first embodiment, and the lamp 12 is set to be turned on for a predetermined period of time (for example, 2 seconds).

At 0, when the receiver 10 receives noise other than the obstacle detection signal transmitted from the transmitter 9, the receiver 10 converts this noise into a control signal as needed and transmits the control signal to the control unit 7. The control signal in this case is a control signal associated with noise, and is not a predetermined control signal that is converted when the receiver 10 receives a signal from the transmitter 9. Therefore, the control unit 7
Even if a control signal due to this noise is input to the control unit 7, the control unit 7 does not perform a process of issuing a command to stop the opening and closing of the shutter curtain 1 to the switchgear 3.

Next, in step # 15, the control unit 7 counts the number of times of input of the control signal based on the noise per unit time (ie, the number of times the receiver 10 receives the noise), and thereby converts this information into the noise. Is output to the discriminating and displaying means 13 as the receiving frequency. Then, based on the noise frequency information, the discriminating display means 13 determines in step # 20
Is used to determine the frequency of noise reception in a plurality of stages. For example, if the noise reception frequency is less than 250 times per second, the lamp 12 of the reception monitor unit 11 is turned on and off at a predetermined blinking interval (for example, 0.3 seconds on, 0.2 seconds off) in step # 25.
To blink.

On the other hand, the frequency of noise reception is 250 per second.
If not, the lamp 12 of the reception monitor unit 11 is blinked at a blinking interval different from the predetermined blinking interval (for example, lighting for 0.1 seconds and turning off for 0.1 seconds) in step # 30.
Therefore, when the electric shutter device is installed in the opening of the building, the quality of the radio wave environment at the installation position of the transceiver is not directly visible, but blinks with the reception of noise as in the present embodiment. By changing the blinking interval of the lamp 12 in accordance with the frequency of reception of noise, the radio wave environment at the position can be known in detail, so that the installation work is simplified and the workability of construction is improved. In this embodiment, the case where the frequency of noise reception is divided into two stages has been described. However, the number of stages may be increased and the noise may be determined in more stages. In this case, the radio wave environment at the installation position of the transceiver can be known in more detail.

It can be set to blink at a predetermined blinking interval (for example, 0.3 seconds on, 0.2 seconds off).

On the other hand, the changeover switch 15 is
In the case of switching to the N side, the lighting or blinking mode of the lamp 14 is also used, and when the receiver 10 receives a signal from the transmitter 9, a predetermined time (for example, 2) is set. (Seconds), the lamp 12 of the reception monitor unit 11 and the lamp 14 near the receiver 10 are simultaneously turned on, and when other noises are received, both the lamps 12 and 14 are simultaneously turned on at a predetermined blinking interval (for example, 0). .
It can be set so that it blinks for 3 seconds and 0.2 seconds off).

0 will be fixed to the upper part of the electric shutter device,
It is desired that the receiver 10 be fixed in a place where the new environment for transmission and reception is free from radio interference. In this case, whether or not the position where the receiver 10 is to be installed is a position where the reception environment is good is determined by setting the changeover switch 15 to the ON side as described above and setting the location where the receiver 10 is to be installed. , The lighting state of the lamp 14 near the receiver 10 that can be easily seen by the operator may be checked.

If the lamp 14 blinks in this state based on the reception of noise, it can be determined that the position is a place where noise is frequently received, and the receiver is searched for a place where the lamp 14 blinks least. Move 10 In this way, a suitable radio wave environment position where the reception of noise is minimized is searched for, and the receiver 10 may be fixed at the position. After installing the receiver 10, the changeover switch 1
By switching 5 to the OFF side, even if the receiver 1
Even if 0 receives noise, it is possible to prevent the lamp 14 from blinking, so that a user who is not familiar with the situation in which the lamp 14 blinks sees the blinking of the lamp 14 and fails or malfunctions. It can prevent you from feeling nervous by misunderstanding etc.

It should be noted that the present invention is not limited to the above-described embodiment, and a sounding means such as a buzzer or a chime may be used as the notifying means in addition to the lamp.
