摘　　要：为了实现运输过程中对食品环境温度的实时监测与记录,本文设计了一种基于ARM7的温度采集与存储系统。系统采用AT91SAM7S64芯片进行控制和DS18B20温度传感器进行温度采集,将采集到的温度数据存储于芯片内部的FLASH中,最后通过串口通信将采集存储的温度数据传送至PC机。结果表明系统能准确地显示出实际环境温度,并且系统反应迅速、体积小,并且成本低廉,可以应用于很多温度监测领域。In order to realize the function to monitor and receive the environment temperature of dairy products during the transportation procedure, a temperature data real-time acquisition and storage system based on ARM7 was devised. This system measure temperature with temperature sensor DS18B20 and save the collected temperature data to flash memory by AT91SAM7S64 microcontroller, temperature data is transported to computer through serial communication. Tests show that this system is of low cost and could display temperature of the circumstances accurately. To make the system much better,it can be used to many different fields of temperature measurement with its feature to small volume and response quickly.
