摘　　要：本课题主要介绍基于AT89C52单片机和DS18B20数字温度传感器的多点温度采集系统。该系统利用AT89C52单片机分别采集各个温度点的温度,实现温度显示、报警等功能。它以AT89C52单片机为主控制芯片,采用数字温度传感器DS18B20实现多路温度的检测,测量精度可以达到0.5℃。该系统采用了LCD1602A液晶显示模块,LCD1602A作为显示器,形象直观的显示测出的温度值。基于AT89C52单片机的单总线多点温度采集系统具有硬件组成简单、多点温度检测、读数方便、精度高、测温范围广等特点,在实际工程中得到广泛应用。The problem introduces AT89C52 monolithic machine and the DS18B20 figure temperature sensor-based multiple spot temperature measurement system mainly. AT89C52 single chip using the system were collected at various temperatures of the temperature, temperature display and alarm functions. It AT89C52 MCU-based control chip, digital temperature sensor DS18B20 the realization of multi-channel temperature detection, measurement accuracy can reach 0.5 ℃. The system uses LCD1602 A liquid crystal display modules,LCD1602 A as a display, the display of visual images to measure the temperature. AT89C52 single chip based on singlebus multi-point temperature measurement and control system with simple hardware components, multi-point temperature, easy reading, high-accuracy, wide temperature range, and other characteristics of the actual projects are widely used
