Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmission control device for controlling indoor equipment.

2. Description of the Related Art A method shown in FIG. 2 is known as a method for controlling a plurality of controlled equipment adapters to a preset setting state by a single control command from a controller which is a control equipment. There is.

The method will be described with reference to FIG. The one shown in the figure is
A high-frequency signal is superimposed on the power line for communication between the controller and the adapter, and no special wiring for control is required. 1 is a power line, which supplies a commercial 100V and constitutes a signal transmission path. The electric devices 2 and 3 are connected to the power line 1 via adapters 4 and 5, respectively. The adapters 4 and 5 have a function of detecting and transmitting whether the electric devices 2 and 3 are in an ON state or an OFF state, and a function of receiving a control command and turning ON / OFF the electric devices. ON / O above
The FF operates by receiving an individual control command in which an address number set in the address number setting means 6 and 7 is added with a command to turn it on or off and the setting set in the changeover switches 8 and 9. Some of them operate by receiving a simultaneous control command. The latter operates when the changeover switches 8 and 9 are "controlled" when receiving the simultaneous control command, and does not operate when "non-controlled" according to the ON and OFF switches. Meanwhile controller 10
Is provided with an individual control switch 11 and a simultaneous control switch 12. When the individual control switch 11 is pressed, an individual control command for controlling only the adapter having the address number set in the address number setting means 13 is transmitted, and when the simultaneous control switch 12 is pressed, the simultaneous control command is transmitted. Also electrical equipment
A display signal is displayed on the display means 14 by receiving a transmission signal from the adapters 4 and 5 as to whether the 2 and 3 are in the ON state or the OFF state.

Problems to be Solved by the Invention In such a conventional transmission control device, the changeover switch 8 or 9 provided in each adapter determines how each adapter responds to the simultaneous control command. Since it has been set, if you increase the number of simultaneous control switches 12 and increase the types of simultaneous control commands, the changeover switch of adapters 4 and 5
The number of 8,9 must also be increased accordingly. This has been an obstacle to miniaturization of the adapter. In terms of appearance, it is desirable to install the adapter inside an electric device, but the switch for the simultaneous control response of the adapter that controls electric devices such as air conditioners must be changed seasonally. It was also difficult to incorporate the adapter into electrical equipment. Furthermore, it is inconvenient to set, change, and confirm the changeover switch at the time of construction because it is necessary to go to the place of the adapter to change over.

Means for Solving the Problems In order to solve the above problems, the present invention provides a signal transmission line,
When a simultaneous control command is received from the controller, a control device is connected which sequentially transmits individual control commands to each adapter in accordance with preset settings.

Action According to the present invention, by connecting the control device for converting the response operation for simultaneous control to the individual control command to the signal transmission path, the response by the simultaneous control can be set at one place of the control device.
Since it is not necessary to provide this changeover switch on the adapter, the adapter can be downsized, the adapter can be built in electric equipment, and the setting, change and confirmation at the time of construction can be done in one place.

Practical Example FIG. 1 is a diagram showing an embodiment in which the control device of the present invention is connected. In FIG. 1, reference numeral 15 is a signal transmission line, which is composed of a power line that also serves as a power supply. The electric devices 16 and 17 are connected to the signal transmission path 15 via adapters 18 and 19 which are controlled devices having address numbers for identifying the electric devices. The adapters 18 and 19 have a function of detecting and transmitting whether the electric devices 16 and 17 are in an ON state or an OFF state, and a function of receiving a control command and turning ON / OFF the electric devices. The ON / OFF operation is performed by receiving the individual control command. The individual control command is the address setting means 20, 2 of the adapter you want to operate.
It is the address number set to 1 with the addition of an ON or OFF command. 22 is a controller, and individual control switch 2
Three and two simultaneous control switches 24A, 24B, address number setting means 25 and display means 26 are provided. Since each operation is the same as the conventional example, the description is omitted.

27 is a control device of the present invention, which is provided with an address number setting means 28, a changeover switch 29 and a setting end switch 30. The controller 27 operates the switches as described below to make the setting.
First, the address number setting means 28 is set to the same address number as the adapter to be controlled. Next, changeover switch 29 (A,
For example, the B switch) is switched to ON when the simultaneous control switch 24A of the controller 22 is pressed and OFF when 24B is pressed. When these settings are completed, the setting end switch 30 is pressed. The above setting is repeated for other address numbers. When the control device 27 thus set receives the simultaneous control command, the control device 27 sequentially transmits the individual control commands to the adapters 18 and 19 having the address numbers set to ON or OFF.

Here, the controller 27 turns ON / OFF that the adapters 18 and 19 have transmitted.
By receiving the state of and storing the current state, the adapter that needs to be changed from ON to OFF or from OFF to ON is known, and therefore an individual control command is transmitted only to that adapter. That is, it is not necessary to send the ON command to the adapter that is already ON. Of course, one control device 27 uses both depending on the control target.

As described above, the changeover switch for setting the response to the control command is conventionally provided in each adapter,
By collectively providing the control device 27 connected to any place of the signal transmission path, the number of changeover switches to be set can be reduced. Further, since only the address number (which is set at the time of the first construction and not changed later) is set by the adapter, there is no inconvenience even if the adapter is built in the electric device. Further, when setting or changing the pattern, or when confirming how it is set, conventionally, it has been confirmed by going to the place of the adapter, but according to the embodiment of the present invention, the setting is made in one place. Can be changed and confirmed.

In addition, when the control target electric equipment is a lighting fixture, it is better to send an ON signal first and then an OFF signal so that there will be no dark moments when the electrical equipment to be controlled is a lighting fixture. If you send it first, the previously lit lights will also go out and a dark moment will occur). Also, if the control target is an air conditioner, the breaker may be cut off when all of them are turned on, so it is better to send an OFF signal first.

EFFECTS OF THE INVENTION According to the present invention, a switch for switching the response of the simultaneous control can be provided in a control device other than the adapter, the adapter can be downsized, and it can be incorporated in an electric device. In addition, it is convenient to check the changeover switch during construction in one place.
