DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a device for remotely controlling electrical equipment that can be remotely controlled using infrared rays or radio waves via a power line.

Conventional technology Traditionally, for convenience, portable remote control transmitters using infrared or wireless radio have been used instead of hand-operated switches for remote control of home video equipment and air conditioning equipment. . On the other hand, there are also existing systems that can centrally or decentrally control household electrical equipment from anywhere indoors rather than from the vicinity of the electrical equipment.

Problems to be Solved by the Invention However, the above-mentioned former type of electrical equipment controlled by a remote control transmitter does not pose a problem when the remote control transmitter is used nearby, but if it is operated in a remote location indoors, for example in an adjacent room. □
In such cases, there is a high possibility that electrical equipment will not operate. or,
Systems that centrally or decentrally control household electrical equipment have the problems described in 31.-1 below. Many modern electrical devices use electronic control systems, and many do not operate simply by turning on the power source (AC power source). 1. When introducing the above system into a home, it is sufficient to use electrical equipment that has an ink face circuit that can be compatible with the system, but if electrical equipment is already installed, when trying to introduce the system. The electrical equipment listed below cannot be controlled.

The present invention solves these conventional problems and allows electrical equipment to be remotely controlled even if they are not in the same room.

Moreover, it is designed to be compatible with existing electrical equipment.

Means to Solve the Problems In view of the above-mentioned problems, the present invention provides an operation signal generating device that converts a power line into a home bus (household information line) and generates infrared rays or radio waves to electrical equipment. and a remote control device that transmits control data to the control signal generator;
An energization detection device for detecting the energization state of the electric appliance is connected to a power line.

action The effect of this technical means is as follows.

The operation signal generator connected to the above electric light line generates the same control signal as a portable remote control transmitter for controlling electrical equipment, and can be controlled from any location indoors using the remote control device.

The operation shown in FIG. 3 will be briefly explained. First, dial the other party's station using the sending phone, and after the receiving phone automatically receives the call, input the type of the target electrical device (in this case, a video tape recorder), and issue a series of power-on commands, channel set, and recording start commands. Perform these operations consecutively. At the start of each operation, the message generating means 14 responds to the effect that the first operation is possible after the arithmetic processing means 12 shown in FIG. 2 processes the long data. Then, when the video tape recorder starts recording, the power supply current increases, so if this current value is detected and exceeds a predetermined value, an ACK (Acknowledgment) is sent to start the operation of the electrical equipment.
