High power intelligent home infrared communication circuit

Abstract

The invention relates to the intelligent home communication field, in particular to a high power intelligent home infrared communication circuit. The high power intelligent home infrared communication 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 signals and performs modulation to convert the signals into square-wave signals, and then sends the square-wave signals to a level shift circuit; the level shift circuit, which performs level shift on the signals and sends the signals to an infrared transmission module; the infrared transmission module, which converts the level shift square-wave signals into infrared signals and conducts transmission; an infrared receiving module, which 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 completes signal output. The high power intelligent home infrared communication circuit has high performance cost ratio, is easy to realize, and has the characteristics of electromagnetic interference resistance, convenient high speed application and flexible space access, and can be used for realizing point-to-point transmission indoor and outdoor, driving high power infrared transmitting tubes and realizing long-distance communication.

Description

Problems solved by technology

[0003] Existing smart home devices are generally connected via Bluetooth or the Internet, which requires additional network communication chips, which are costly. Moreover, existing old-fashioned household appliances generally use infrared communication, and there are few ways to use digital network communication. Although existing household appliances also have Products embedded with smart chips are expensive and not suitable for promotion. Due to the high driving power requirements of the infrared emitting tube, the communication distance is limited in the case of low driving power, so it is not suitable for long-distance use.
