基于单片机多回路温度采集系统的设计

摘要

the multi-channel temperature gathering system by the master control regulator,the temperature gathering electric circuit,the temperature display circuit,and the keyboard entry control circuit is composed.It makes the control and the data processor,intel igent temperature sensor DS18B20 using monolithic integrated circuit AT89C52 makes the temperature detector,the LCD display tube makes the temperature demonstration output unit.The hardware electric circuit quite is simple,the cost is low,the temperature measurement scope is big, and the measuring accuracy is high,reading demonstration is direct-viewing,easy to operate.%多路温度采集系统由主控制器、温度采集电路、温度显示电路及键盘输入控制电路组成。它利用单片机AT89C52做控制及数据处理器、智能温度传感器DS18B20做温度检测器、LCD显示管做温度显示输出设备。硬件电路成本较低，测温范围大，测量精度高，读数显示直观，使用方便。
