摘　　要：在电工场合中,重要部件的温度变化是必须密切注意的,一次疏忽都可能引发事故,造成无可挽回的损失。因此,这些场合一般都装有具有自动报警功能的测温系统,智能测温系统还要提供下载接口,以便操作者读取数据并分析事故多发阶段及其诱因,达到防范于未然。本文介绍了利用USB接口芯片CH375在智能测温系统中保存实时数据的方法,重点介绍对外接USB存储设备进行读写的原理和步骤,并提出了一种在资源占用上比芯片厂商提供的文件管理层操作更为优化的程序设计方法。It is important to watch out for temperature change of primary components in electrical places, otherwise accidents would occur without careful attention and cause great loss. Therefore, Temperature Detecting System with auto-alarming function is essential for these places, and the intelligent ones should offer downloading interfaces for data analysis and accident protection. This paper introduces the implementation of saving real-time data in Intelligent Temperature Detecting System based on USB interface chip CH375, focuses on how to read and write external USB storage equipments, and suggests a more available method to deal with file management system than that offered by chip manufacturer.
