Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control transmitter for an automatic opening / closing device for remotely controlling an automatic opening / closing device such as an electric shutter or an electric gate for automatically opening / closing an entrance, and more particularly, to a remote control transmitter for a plurality of automatic opening / closing devices. The present invention relates to an apparatus in which devices are individually remotely controlled by one transmitter.

[0002]

2. Description of the Related Art In recent years, devices such as shutters provided outdoors and chain gates and gates provided outdoors are configured using actuators such as electric motors and remotely controlled using remote control transmitters. It opens and closes automatically by operation. Two or more automatic switchgears of this type may be installed at different locations, such as the entrance and exit of a building or site. In such a case, a single remote control transmitter can be used to control multiple automatic switchgears. It would be very convenient if the devices could be remotely controlled individually, and various remote control transmitters for realizing this were proposed (see, for example, Japanese Utility Model Laid-Open No. 5-69294).
Has been put to practical use.

For example, as remote control transmitters for remotely controlling two automatic opening and closing devices individually, those shown in FIGS. 6 and 7 are known. The remote control transmitter shown in FIG. 6 has an open switch a corresponding to each automatic opening and closing device,
Two sets of a close switch b and a stop switch c are provided, and when any one of the three switches a to c corresponding to the automatic opening / closing device to be remotely operated is operated, separate code signals and execution signals are respectively issued. Accordingly, the automatic opening / closing device can be operated to open, close, or stop.

The remote control transmitter shown in FIG. 7 has a set of an open switch a, a close switch b, and a stop switch c.
And two selection switches d,
d, a selection signal is generated when the selection switch d is operated, and an execution signal is generated when the open switch a, the close switch b, or the stop switch c is operated in a state where the selection signal is generated, so that a desired signal is generated. The automatic opening and closing device can be operated to open, close or stop.

[0005]

However, in the above-mentioned conventional remote control transmitter, there is a problem in that the cost is high because of the large number of switches a to d. In particular, in the remote control transmitter shown in FIG. 6, three switches a to 3 each time the number of the automatic opening / closing device to be remotely controlled increases by one.
c must be added, and the problem is remarkable.

Further, in the remote control transmitter shown in FIG. 6, there is a possibility that the switches a to c may touch other things and erroneously operate the automatic opening / closing device during storage in a car or the like. On the other hand, in the remote control transmitter shown in FIG. 7, the automatic opening / closing device does not operate unless the open switch a, the close switch b, or the stop switch c is operated after operating the selection switch d, thereby preventing erroneous operation. On the other hand, when stopping the automatic opening / closing device in an emergency, there is a possibility that the two-stage switch operation delays the emergency stop.

SUMMARY OF THE INVENTION The present invention has been made in view of the foregoing, and has as its object to reduce the number of switches as much as possible to reduce the cost, to prevent erroneous operations and to prevent an emergency stop. An object of the present invention is to provide a remote control transmitter for an automatic opening / closing device which can be secured and is excellent in safety.

In order to solve the above-mentioned problems, a first aspect of the present invention is a remote control transmitter for switching a plurality of automatic opening and closing devices to open, close, and stop by individual remote control. Two switches for opening and closing, a plurality of stop switches respectively corresponding to the plurality of automatic opening and closing devices, and an automatic opening and closing device corresponding to any one of the plurality of stop switches when one of the plurality of stop switches is operated. Control means for outputting an operation stop signal of the automatic opening / closing device when the opening or closing switch is operated following the operation of the stop switch, and an output of the control means. A radio wave transmitting means for transmitting a radio wave based on a signal is provided.

In this configuration, when the stop switch corresponding to the automatic opening / closing device to be remotely operated is operated, the operation stop signal of the automatic opening / closing device is output from the control means, and the operation from the radio wave transmitting means is performed based on this output signal. The stop signal is transmitted, and the automatic switching device stops. When the switch for opening or closing is operated following the operation of the stop switch, an opening signal or a closing signal of the automatic opening / closing device is output from the control means, and a predetermined radio wave is transmitted from the radio wave transmitting means based on the output signal. Then, the automatic opening and closing device performs an opening operation or a closing operation. According to this operation procedure, a desired automatic opening / closing device can be easily stopped in an emergency simply by operating the stop switch. Also, even if another member touches the opening switch or the closing switch, no radio wave is transmitted from the radio wave transmitting means, so that the automatic opening / closing device does not erroneously open or close. In addition, since the stop switch also has a function as a selection switch, the number of switches is reduced accordingly.

According to a second aspect of the present invention, there is provided a preferred embodiment of a display lamp provided in the remote control transmitter for an automatic opening and closing device according to the first aspect. That is, the display lamp is constituted by a plurality of types of light emitting diodes corresponding to the number of the automatic opening / closing devices, and emits light in different colors according to the automatic opening / closing device selected by the selective operation of the stop switch, and transmits radio waves. Lighting or flashing is provided so that the difference between the middle and the standby time from when the stop switch is operated until a predetermined time elapses can be recognized. In this configuration, 1
The selection status and the radio wave transmission status can be displayed together with only one display lamp.

That is, in FIG. 4, after the start, it is first determined in step S1 whether or not the stop switch 3 (stop A) has been operated. If the determination is YES, in step S2, for example, the selection of the entrance-side automatic opening / closing device 5 frames including an ID code (ID code identification signal and selection identification signal in FIG. 3) and a stop signal (operation identification signal meaning a stop command in FIG. 3) including Turns on the display lamp 5 in red (that is, by light emission of the red light emitting diode).

Subsequently, after the timer A is started in step S3, the display lamp 5 flashes in red at an interval of 0.2 seconds in step S4 to indicate that the A transmission standby state is set. Next, it is determined in step S5 whether or not the open switch 1 has been operated, in step S8 whether or not the close switch 2 has been operated, and in step S10, whether or not the timer A has counted 2 seconds. I do.

Then, the determination in step S5 is YES.

During the transmission, the display lamp 5 is similarly illuminated in red, and then the process proceeds to step S7.
Further, when the determination in step S10 is YES, that is, when the open switch 1 and the close switch 2 are not operated in the A transmission standby state and two seconds have passed, the process directly proceeds to step S7. In step S7, the red display of the display lamp 5 is turned off, and the control circuit returns to the standby state, and returns to step S1.

On the other hand, if the determination in step S1 is NO, the process proceeds to FIG. In FIG. 5, it is first determined in step S11 whether or not the stop switch 4 (stop B) has been operated. If the determination is YES, step S1 is performed.
Then, if the determination is NO, the process returns to step S1.

In step S12, an ID code including a B signal indicating the selection of the automatic opening / closing device on the exit side and a stop signal are transmitted for 5 frames, and during the transmission, the display lamp 5 is turned green (that is, the green light emitting diode emits light). Lights). Subsequently, after the timer B is started in step S13, the display lamp 5 blinks in green at an interval of 0.2 seconds in step S14 to indicate that the B transmission is in a standby state. Next, it is determined in step S15 whether or not the open switch 1 has been operated, in step S18 whether or not the close switch 2 has been operated, and in step S20, whether or not the timer B has counted two seconds. I do.

The determination in step S15 is YE
In the case of S, that is, when the release switch 1 is operated, the ID code including the B signal and the release signal are transmitted in five frames in step S16. During the transmission, the display lamp 5 is lit in green, and then the process proceeds to step S17. I do. Also,
When the determination in step S18 is YES, that is, when the close switch 2 is operated, B is determined in step S19.
The ID code including the signal and the closing signal are transmitted for 5 frames,
During the transmission, the display lamp 5 is similarly turned on in green, and then the process proceeds to step S17. Further, step S
If the determination in Step 20 is YES, that is, if two seconds have passed without the open switch 1 and the close switch 2 being operated in the B transmission standby state, the process directly proceeds to Step S17. In step S17, the green display of the display lamp 5 is turned off, and the control circuit returns to the standby state, and returns to step S1.

Next, the operation and effect of the above embodiment will be described. When the remote control transmitter A is used to open and close, for example, the automatic opening / closing device on the entrance side of the two automatic opening / closing devices, firstly, The stop switch 3 corresponding to the automatic opening / closing device on the side is operated. Then, the control unit 11
The ID signal including the A signal indicating the selection of the entrance-side automatic switching device from the transmission circuit 12 under the control of
A frame is transmitted, whereby the automatic opening / closing device on the entrance side stops. Subsequently, when the open switch 1 or the close switch 2 is operated, the ID signal including the A signal is transmitted from the transmission circuit 12.
A code and an open signal or a close signal are transmitted for 5 frames,
Thereby, the automatic opening / closing device on the entrance side performs the opening operation or the closing operation.

The operation of the automatic opening / closing device on the exit side is the same as the operation of the automatic opening / closing device on the entrance side, except that the stop switch 4 corresponding to the automatic opening / closing device on the exit side is first operated.

According to such an operation procedure, when it becomes necessary to stop one of the automatic opening and closing devices in an emergency, the emergency operation can be easily performed simply by operating one of the stop switches 3 or 4 corresponding to the automatic opening and closing device. It can be stopped and safety can be ensured. In addition, since the transmission circuit 12 does not transmit a radio wave even when another object touches the opening switch 1 or the closing switch 2, the automatic opening / closing device does not erroneously open or close, thereby preventing erroneous operation. be able to. Furthermore, even if the remote control transmitter A is operated during the operation of the automatic opening / closing device, the stop operation is performed first, so that the safety can be further improved.

In addition, since the stop switches 3 and 4 also have a function as a selection switch for selecting two automatic opening and closing devices, the number of switches can be reduced correspondingly. In the case of the present embodiment, the number of switches is four, two less than the conventional remote control transmitter shown in FIG. 6, and one less than the remote control transmitter shown in FIG. The effect that the operability can be improved by reducing the number of remote controllers and the cost can be reduced can be achieved.

In addition, the display lamp 5 is composed of a red light emitting diode and a green light emitting diode. Flashes red in the A transmission standby state until elapse of 2 seconds, lights up green during transmission when remotely controlling the automatic opening / closing device on the exit side, and transmits B until 2 seconds elapse from the time when the stop switch 4 is operated. Since it flashes green in the standby state, the operator of the remote control transmitter A can easily recognize the operation status and the radio wave transmission status, which can contribute to prevention of erroneous operation.
Moreover, since there is only one display lamp 5, the remote control transmitter A is simple in appearance and easy to see.

It should be noted that the present invention is not limited to the above embodiment, but encompasses various other forms.
For example, in the above-described embodiment, a case has been described in which two automatic opening and closing devices are remotely controlled by one remote control transmitter.
The present invention can be similarly applied to a case where three or more automatic opening / closing devices are individually and remotely controlled by one remote control transmitter.

In the above embodiment, each of the switches 1 to
The control means 11 for controlling the transmission circuit 12 according to the operation status of 4 is constituted by a control unit 11 composed of a microcomputer or the like. Instead of this control unit 11, it is constituted by using various electronic circuit elements. Of course, it is good.

[0027]

As described above, according to the remote control transmitter for an automatic opening / closing device of the present invention, a desired automatic opening / closing device can be easily emergency-stopped only by operating a stop switch in an emergency, and an open switch. Alternatively, even when another object touches the closing switch, the automatic opening / closing device does not erroneously open or close, and thus erroneous operation can be prevented and safety can be enhanced. Further, even if the remote control transmitter is operated during the operation of the automatic opening / closing device, the stop operation is performed first, so that the safety can be further improved. In addition, since the stop switch also has the function of the selection switch, the number of switches can be reduced, and the cost can be reduced.

In particular, according to the second aspect of the present invention, one display lamp composed of a plurality of types of light emitting diodes corresponding to the number of automatic opening / closing devices is lit in different modes according to the selection status and the radio wave transmission status. Or, since it flashes, the operator of the remote control transmitter can easily recognize the operation status and the radio wave transmission status, and has the advantages that the appearance is simple and easy to see.
