摘要
基于ARM和DS18B20的温度监测系统使用SAMSUNG公司的32位ARM微控制器S3C2440作为数据采集单元,数字温度传感器DS18B20作为温度检测元件。给出了系统的总体设计方案、硬件设计及软件框图。对测得的数据采用防脉冲干扰平均滤波法进行数字滤波。同时,通过串行总线完成了采集系统与上位计算机的连接,实现了采集系统的网络化监测功能。
Based on the ARM and DS18B20 temperature monitoring system use ARM as the data acquisition unit and digital temperature sensor DS18B20 as the temperature detection element. The overall system design, hardware design and software block diagram are given. The digital filtering of measured data is the average median filtering method.Meanwhile, the acquisition system connects the host computer via the serial port in order to achieve the network monitoring function.
