Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a relay device used in a home automation system that controls electrical appliances using electromagnetic waves such as infrared rays.

(Prior Art) In recent years, the following systems, for example, have been developed as home automation systems that utilize infrared signals. In other words, electrical appliances such as lighting fixtures and near conditioners placed in multiple rooms are each equipped with a controller equipped with a receiving section, and an infrared signal is sent from a common remote control switch to the receiving section of each controller. Each electrical appliance is controlled by this.

(Problems to be Solved by the Invention) However, in the above-mentioned system, the walls that partition each room block infrared signals, making it difficult to control electrical appliances without entering each room.

(Means for Solving the Problems) The present invention has been made to solve the above problems.
The gist of this is that there is a receiving section that receives electromagnetic wave signals from a remote control switch and converts them into electrical signals, an electrical signal transmitting section that transmits the electrical signals generated in this receiving section, and an electrical signal sent from the electrical signal transmitting section. A relay device for a home automation system is specially designed to include a transmitting section that converts the electromagnetic wave signal into an electromagnetic wave signal and sends it to a receiving section of a controller for controlling electrical appliances.

(Operation) The electromagnetic wave signal emitted from the remote control switch is received by the receiving section of the relay device, where it is converted into an electrical signal. This electrical signal is sent to the transmitting section via the electrical signal transmission section. The transmitting section converts the electrical signal into an electromagnetic wave signal, and sends this electromagnetic wave signal to the receiving section of the controller for controlling the electrical appliance. The controller controls the electrical appliance based on the electromagnetic wave signal received by the receiver. In this way, it is possible to send an electromagnetic wave signal from a remote control switch to a controller located in an area where it is not possible to directly send an electromagnetic wave signal via a relay device.
