Wireless infrared sending module for smart home

Abstract

The invention relates to the field of smart home communications, in particular to a wireless infrared sending module for a smart home. The wireless infrared sending module is characterized by comprising an input module, an amplification modulation circuit, a signal distributor, an amplitude modulation circuit, an infrared emission module, an antenna matching circuit and an antenna, wherein the amplification modulation circuit amplifies a signal, modulates the signal, converts the signal into a symmetric square wave signal and sends the converted signal to the signal distributor, the signal distributor forwards the square wave signal into two paths of signals and sends the two paths of the signals to the amplitude modulation circuit and the antenna matching circuit respectively, amplitude modulation is conducted on the signal through the amplitude modulation circuit, the signal subjected to amplitude modulation is sent to the infrared emission module, the infrared emission module converts the modulated signal into an infrared signal and sends the infrared signal, the antenna matching circuit receives the signal of the signal distributor and sends the signal to the antenna, and the antenna completes sending of the wireless signal. The wireless infrared sending module for the smart home is high in price-performance ratio, easy to achieve, resistant to electromagnetic interference, convenient to apply at a high speed and flexible in space access, can be used for achieving point-to-point transmission indoors and outdoors and can achieve any amplitude modulation of signal square waves, power suitable for output can be selected according to different installation environments, and receiving is convenient.

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, but long-term high-power The output will lead to excessive power consumption, and the heat dissipation of the system will also be affected to a certain extent. In the case of infrared emission, existing home appliances also need to be connected to the network for wireless communication, so as to realize home intelligence.
