摘　　要：设计了一种温度采集系统,以单片机AT89C51为控制核心,由一线式数字温度传感器DS18B20对温度进行信号采样,以数字信号的形式由单片机读取,并通过LED实时显示温度。采用模块化结构进行软件设计,程序的逻辑关系十分清晰,降低了硬件设计的复杂性。A temperature acquisition system with MCU AT89C51 as the control core is designed, by using the 1-wire digital temperature sensor DS18B20 to sample temperature signals which are read by the MCU in the form of digital signal and displayed through the LED. Using the software design of modular structure makes the logic of the program very clear and reduces the complexity of hardware design.
