专利汇可以提供Repeating installation for home automation system专利检索,专利查询,专利分析的服务。并且PURPOSE: To attain control of a controller at the area where a electromagnetic wave signal cannot be directly sent by converting and transmitting the electromagnetic signal from a remote control switch to an electric signal, converting the electric signal and sending it to a controller for controlling an electric appliance.
CONSTITUTION: When a remote control switch 14 arranged at one side room 10 is operated and an infrared ray signal A is sent from a transmitting part 14b to a light-receiving element 44 of a receiving part 42a of a repeating installation 40, an electric signal B corresponding to the infrared ray signal is generated from a receiving part 42a. The electric signal B comes to be an electric signal E of a rectangular pulse through an amplifying circuit 51, a detecting circuit 52 and a waveform shaping circuit 53, an AND circuit 55, only while the electric signal E is inputted, outputs an electric signal F composed of a short pulse group from an oscillating circuit 54 to the base of a transistor 48, an infrared ray signal G equal to the infrared ray signal A is outputted from a light emitting signal A of a transmitting part 43b, sent to a receiving part 22a of a controller 22 provided at an air conditioner 21 of other room 20 and the air conditioner 21 is controlled.
