摘要
以LM386和红外光收发对管为核心元件,通过红外光定向传输语音信号,并具有环境温度实时检测功能。该设计中,音频信号经过发射电路转换为光强变化的红外光信号,接收电路接收到红外光,经LM386集成音频运放处理通过扬声器还原成声音。由DS18B20采集环境温度,经单片机STC12C5A60S2数据编码后发射,接收电路接收的红外光信号,经单片机解码后通过LCD液晶显示实时温度。
The design is based on LM386 and infrared transceiver on the tube as the core components,optical directional transmission of voice signals through infrared,and has a temperature in real-time detection. In the design,the audio signal passes through the transmission circuit into light intensity change of the infrared light signal,the receiving circuit receives the infrared light,the LM386 audio amplifier integrated processing back into sound through the speaker. The DS18B20 temperature information gathering,after the microcontroller STC12C5A60S2 data encoding transmitter and receiver circuit receives infrared light signals,after decoding the microcontroller via the LCD display real- time temperature.
