摘　　要：以温度的采集处理和显示为目的,研究了基于AT89C52单片机的温度检测及显示的设计方法。以AT89C52为核心控制芯片,采用A/D转换模块对8路温度进行巡回采样检测,并用RT12864液晶模块来显示文字和实时变化曲线图,键盘操作设置系统参数,温度传感器采用PRT浸入式铂热电阻传感器。经过AT89C52的高速运算处理,实现多路温度值的检测和相应温度值的曲线显示。This paper takes the temperature gathering and its demonstration as the goal. It studies that control method of temperature examination and its demonstration design based on the AT89C52. This system adopts AT89C52 as the core control chip,it uses A/D transformation module to sample 8 positions temperatures and uses RT12864 liquid crystal module to display characters and the real - time variety graph, the keyboard operation sets system parameters, the temperature sensor uses the PRT immersion temperature sensor. AT89C52＇s high speed operation processing realizes multichannel temperature value numeral demonstration and the corresponding temperature value variety Dlot demonstration.
