Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a home automation system (H) for monitoring and controlling each controlled device in a house.
A system) and the like, the present invention relates to a control terminal device suitable for use in an HA system including an electric device such as a lighting controlled by directly opening and closing a power supply line as a control target.

[0002]

2. Description of the Related Art Conventionally, when opening and closing an electric device in a home by a control terminal device of an HA system, the controlled electric device is directly connected to a control terminal device of the HA system, and a control relay in the control terminal device is connected. There is a technology to open and close the power supply line of the electric equipment that becomes the load by
22830 and the like.

In such a conventional technique, a control circuit and a control relay for controlling a load are built in the control terminal device, and a load switch for the control terminal device is opened and closed by a controller provided separately from the control terminal device. The control terminal device, which transmits a signal and receives the load opening / closing signal, opens / closes the power supply line of the electric device by the built-in control relay, controls the electric device of the load, and outputs the result as a monitor signal to the controller. Then, the controller could know the control result from the monitor signal.

Conventionally, the control terminal device and the controller constitute an HA system.

[0005]

In the above prior art, when the control circuit in the control terminal device or a separately provided controller cannot open / close the control relay due to a power failure or the like, it is possible to open / close control the electric equipment of the load. There were times when it disappeared.

Further, in the above-mentioned prior art, in the control terminal device of the type which is installed by embedding it in the wall surface, it is usually housed and mounted in the switch box like a general wall switch. In the case of a control terminal device with a switch that can open and close electric equipment such as lighting, it is generally required that it can be accommodated in a switch box for one piece. Due to the restriction, even in the case of an electric device that can open and close a normal wall switch, the opening and closing control may not be possible in the control terminal device for a large load current.

In the above prior art, the control terminal device, together with the controller, is a main component of the HA system.
The person who supplies the product by the HA maker and installs the HA system must always install and use the control terminal device supplied by the HA maker.

However, in the case where the control terminal device is provided with a switch for opening and closing electric equipment such as lighting of a load, the control terminal device can be adjusted according to the design and purpose of the room in which the control terminal device is installed. I couldn't choose the type. Especially in the case of the method of embedding it in the wall surface, the desired color and shape vary depending on the preference of the person who installed it, and it was almost impossible for the control terminal device that the HA maker can supply to meet such a request. ..

An object of the present invention is to solve the above problems and enable the load to be turned on and off even when the HA system is down due to a power failure or the like and the load cannot be turned on and off in the HA system control terminal device. And provide an HA system that is easy to use, and also provides a control terminal device for HA system that has a load current switching capability equivalent to that of a general wall switch, and further, an operation of a design desired by the person who installs the HA system. It is to be able to use the switch.

[0010]

In order to achieve the above object, the present invention relates to a HA system control terminal device for controlling an electric device such as a lighting controlled by directly opening and closing a power supply line. A self-holding type control relay having two circuit contacts is provided, one end of a load coil of a current transformer having two load coils is connected to the common side of the control relay, and an external connection terminal is provided at the other end of the load coil. Provided, the normally closed contact side of one circuit of the self-holding type control relay and the normally open contact side of the other circuit are respectively connected,
An external connection terminal portion is provided at the two connection portions, a control portion for controlling the control coil of the self-holding type control relay is provided, and a control bus for transmitting a control signal of the home automation system is connected to the control portion, The detection coil of the current transformer is connected to the control unit via a current detection circuit, and an address setting unit for setting the address of the HA system control terminal device is provided and the address setting unit is connected to the control unit. HA
Configured the control terminal for the system.

[0011]

In the HA system control terminal device, when the built-in control unit receives a control signal from the controller separately provided via the control bus, the detection current of the detection coil of the current transformer is detected by the current detection circuit. The operating state of the electric equipment of the load is monitored by the current value, and when the switching operation of the opening and closing is necessary, the control relay of the two circuits and two contacts is opened or closed. Due to the self-holding function of the control relay, the state of the control relay is held even during a power failure. A current flows through either one of the load coils of the current transformer connected to the control relay when the load is in the energized state.

To the external connection terminal portion, the commercial power supply, the electric equipment of the load, the 3-way wall switch, and the control terminal device are electrically connected in series, and the 3-way wall switch and the control terminal are connected. By operating either of the devices, it is possible to control the opening and closing of the electrical equipment of the load. Further, the address for identifying the control terminal device from other terminal devices is set by the address setting unit.
