Smart home infrared communication circuit

Abstract

The invention relates to the smart home communication field, in particular to a smart home infrared communication circuit. The circuit includes: an input module, which is used for receiving signals and sending the signals to an amplification modulation circuit; the amplification modulation circuit, which amplifies the signals and performs modulation to convert the signals into symmetric square wave signals, and then sends the square wave signals to an infrared transmission module; the infrared transmission module, which converts the square wave signals sent by the amplification modulation circuit into infrared signals and performs transmission; an infrared receiving module, which receives infrared signals, completes optical-to-electric signal conversion and sends the signals to an amplification demodulation circuit; the amplification demodulation circuit, which conducts amplification-filtering demodulation treatment on the signals sent by the infrared receiving module and then sends the treated signals to an output module; and the output module, which receives the signals sent by the amplification demodulation circuit and completes output. With high performance cost ratio, the smart home infrared communication circuit is easy to realize, has the characteristics of electromagnetic interference resistance, convenient high speed application, and flexible space access, and can be used for indoor and outdoor point-to-point transmission.

Description

technical field [0001] The invention relates to the field of smart home communication, in particular to a smart home infrared communication circuit.
