【电子开题报告范文】基于ARM的双平板导热系数测定仪的研制摘要：现有的平板式导热系数测定仪存在测量时间长，操作不便等问题。针对这些问题，本课题研制了一种以微处理器ARM为核心的新型双平板式导热系数测定仪。其方法是通过嵌入式mC/OS-Ⅱ实时操作系统和友好的人机界面实现仪器的全自动控制、数据采集和处理以及导热系数的计算、显示和打印输出。其测量精度符合导热仪国家标准，并具有测量时间短、数据准确、自动化程度高、体积小等优点，是现代化的智能仪器。该仪器可以广泛用于耐热和保温材料的生产企业、相关质量检验部门和单位、高等院校和研究所等科研单位。
关键词：ARM、mC/OS-Ⅱ、嵌入式系统、导热系数
Abstract: At present, there are some problems about the instrument measuring heat-transfer coefficient on the market such as long time measuring, complicated operation and so on. We have developed an instrument measuring heat-transfer coefficient with ARM as MCU to solve the problems. The characters of it are that it can realize full automatic controlling, data collection and disposal by embedded OS mC/OS-Ⅱ. The heat conductivity can be displayed and printed out. The measure precision accords with the nation standard. Short measure time, precise result, high automatic degree and small
