Description

[Detailed description of the invention] Industrial applications The present invention is applicable to remote control of electrical equipment and control of energization status.

This invention relates to a remote control device that remotely monitors whether or not devices are connected.

Conventional configurations and their problems Generally, when controlling various electrical devices using power line carriers or dedicated lines in homes or centrally monitoring the operating status of devices, it is difficult to connect the electrical outlets to which the devices are connected. The terminal's control circuit is integrally configured. In some cases, the control circuit is also embedded in the wall, along with the outlet, in consideration of appearance. Conventionally, this type of control circuit always supplies power to the control circuit even if the plug of the device is inserted into the outlet or unplugged.
Because it was being used as a computer and constantly consuming several watts of electricity,
This has the disadvantage of consuming unnecessary power.

Moreover, in the case of a remote control device using power line transport as shown in FIG. 1, it is a centralized remote control device 1 or a television.

A large number of remote control terminal control devices 3 that control loads 2 such as lighting are connected. At this time, if the control device 3 of the terminal is always connected to the power line regardless of whether a load is connected or not, the impedance of the power line decreases, resulting in a disadvantage that the attenuation of the carrier signal increases.

Purpose of the Invention In view of the above-mentioned conventional drawbacks, the present invention supplies power to only the minimum necessary control circuits of remote control terminals in homes etc., thereby preventing wasteful power consumption.
In the case of a remote control device using power line transport, the purpose is to make the impedance of the power line as high as possible to ensure reliable signal transmission.

Structure of the Invention In order to achieve the above-mentioned object, the remote-controlled JP-A-Sho G
O-70939(2) is configured so that power is supplied to the control circuit only when the device is connected to the outlet.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In Figure 2, 4 is a control circuit for a remote control terminal;
The receiving circuit 9 is composed of a transmitting circuit, a power supply circuit, and the like. 6
is connected to the commercial power source at the blade holder that constitutes the outlet. 6 is a movable button protruding from the front of the outlet body; 7 is a movable contact connected to one of the blade receivers 5 and operated by the movable button 6; 8 is a fixed contact connected to the control circuit 4 and facing the movable contact 7. It is. The other blade receiver 5 that is not connected to the movable contact 7 is connected to the control circuit 4.

When the plug of the device is not connected to the outlet in the above configuration, the movable button 6 is not pressed as shown in FIG. 2, so the movable contact 7 and the fixed contact 8 are not electrically connected. Therefore, power is not supplied to the control circuit 4.

However, when you insert the plug of the 5 Benny device into the outlet, the movable button 6 is pressed on the end of the plug.
is pressed in the direction of the arrow, the movable contact 7 and the fixed contact 8 are connected, and power is supplied to the control circuit 4.

FIG. 3 shows another embodiment of the present invention, in which numeral 4 is the same control circuit as shown in FIG. 9b questions and 1
0a and 10b are electrically insulated from each other via insulating materials 11 and integrated. One of the blade holders 91L and 10a is connected to a commercial power source,
The other blade holder 9b.

1ob is connected to the control circuit 4. 12 is an electric wire connected to a commercial power source.

In the above configuration, if the plug of the device is not connected to the outlet, the blade receivers 9 and 10 are not electrically connected, and therefore no power is supplied to the control circuit 4. However, when the plug of the device is inserted into the outlet, the blade holders 9 and 10 are electrically short-circuited by the plug's blade metal fittings, and power is supplied to the control circuit 4. Incidentally, the blade receiving portion 6 and the blade receiving portion 9, 10 described above may be configured such that only one of them is electrically connected only when a device is plugged in.

4 to 6 show circuit diagrams of the embodiment,
Figure 4 shows a device that only has the function of determining whether the device is connected to an outlet, and the blade rests 9 and 10.
When the device is connected to the outlet, power is supplied to the control circuit 4.

The control circuit 4 superimposes a signal indicating that a device is connected on the commercial power source and transmits the signal.

Fig. 5 shows an embodiment in which, in addition to the function of determining whether the equipment shown in Fig. 4 is connected, it is also possible to determine whether the equipment is energized. The other side is connected to the control circuit 4 by connecting the plug of the device to the outlet, and there is no connection between the point directly connected to the control circuit 4 and the outlet. A current transformer (C, T,) 1s is provided for determining whether or not the current is energized.

7 ” -' Figure 6 shows how to turn on the equipment connected to the outlet by remote control.
In this embodiment, a relay 14 driven by the control circuit 4 is provided in place of c, 'r, and 13 in FIG. The signals superimposed on the terminal remotely control the ON and OFF of connected devices. Of course, C,
It is also possible to provide both the ON/OFF control and the energization monitoring of the device by providing the T, 13 and the relay 14. Note that in each figure, 16 indicates a commercial power source.

Effects of the Invention As described above, according to the remote control device of the present invention, power is supplied only to the control circuit of the terminal to which the device is connected, so there is no wasted power consumption, and it is possible to use the power line transport method. In this method, the reduction in line impedance due to the connection of the control circuit to the commercial power source can be minimized, and the conventional problems have been solved.

In addition, with the configuration of the embodiment shown in FIG. 3, the effects of the present invention can be obtained with almost the same component configuration as the currently commonly used plug, so the present invention can be implemented at a very low cost. becomes possible.
