| 摘 要： | 采用红外发射管和红外接收管实现了模拟信号和数字信号的红外通信。红外模拟语音系统中，将声音信号转化来的电信号作为模拟信号直接发送，在接收端经过集成放大LM386芯片等处理后，将电信号还原成声音信号，实现红外模拟通信。红外数字通信系统中，增加一路数字信道，采用数字温度传感器DS18B20实时对温度进行采集，通过单片机STC89C52控制将数字信号发送，在接收端经过非门输入单片机通过1602得以显示。

| Abstract: | This system adopts the infrared transmitting tube and infrared receiving tube for analog signal and digital signal can be transmitted infrared communication. In a voice infrared simulation system,the voice signal conversion to electrical signals as the analog signal sent directly,at the receiving end through integrated amplifier LM386 chip processing,will eventually electrical signals back into sound signal,so as to realize the infrared communication. In the infrared digital communication system,by adding all the digital channel,using digital temperature sensor DS18B20 for temperature acquisition in real time,and STC89C52 microcontroller control to digital signal,finally at the receiving end through the gate input single-chip microcomputer by 1602 to show. |
