智能温度测量系统设计

以AT89C52单片机作为微控制器，设计了一个智能温度测量系统。该系统通过DS18B20温度传感器实现环境温度的采集和A/D转换，模数转化后的电信号送入AT89C52单片机，再通过单片机将其送入LCD1602数码管进行显示。通过实验结果可以看出，相比较传统的温度采集方法，该系统能够快速准确地检测温度，并且检测精度可以达到0.1 ；同时，该系统具有过温点设定值调节及温度上下限蜂鸣提示的优点。

Design of Intelligent Temperature Measurement System

This paper designs an intelligent temperature measurement system based on AT89C52 single chip computer. The temperature is detected by digital temperature sensor DS18B20. DS18B20 collects and converts the temperature signal into data signal. Then the signal is analyzed and processed by single chip computer, and showed by LCD1602. Experimental result shows that the system can measure temperature with higher precision than traditional methods of temperature collection. Its detection accuracy can reach 0.1 . In addition, the system has advantages of adjusting overheat and prompting temperature upper and lower limits.
