摘　　要：目的:研制一种用于野外训练或作战使用的车载温度记录仪。方法:以单片机ATmega48为控制核心,利用数字温度传感器、LCD、蜂鸣器等元器件。结果:实现了温度的监测,并且可实时显示并自动记录采集到的温度数据,将其保存在记录仪内的非易失存储器CAT24C64中,同时具有温度报警等功能。结论:此温度记录仪采集周期短,记录时间长、灵敏度高、性价比高,体积小巧便于携带,可广泛应用于医药、食品、化工、电子制造、仓储、物流以及农业等诸多行业的温度记录。Objective To research and develop a new type of temperature recorder system of vehicle-mounted blood bankwhich is used in the field training and combat. Methods Based on ATmega48 SCM as control core, the components including digital temperature recorder, LCD, buzzer and so on are used. Results The recorder can not only monitor temperature and display real-time, but also store the data in the recorder of the serial EEPROM （CAT2dC64）. Additionally, when the temperature exceeds the given range, it can be automatic alarm. Conclusion The temperature recorder with a short collection cycle, the record for a long time and high sensitivity, cost-effective, small size and easy to carry, etc., can be widely used in medicine, food, chemicals, electronic manufacturing, warehousing, logistics, as well as agriculture and other sectors.[Chinese Medical Equipment Journal, 2009,30 （3） ：28-30]
