摘要
本文介绍一种基于PC机的高精度实时温度自动测定系统。运用铂电阻四线制测温原理 ,采用研祥PCL - 81 6HA/D转换卡进行信号采集和转换 ,利用面向对象的高级程序设计语言VisualC ++进行软件设计。该系统在煤发热量测定仪器中得到了应用 ,具有精度高、操作简单、可靠性好。
A high precision temperature measuring system based on PC was introduced. The hardware structure contained measuring temperature circuit by use of Pt resistance and PCL-816H A/D card, and the software was programmed using Visual C++,an OOP language. The system was applied to the instrument of coal calorimetry. And it shows the system has many characteristics , such as high precision, easy operation, high reliability, friendly interface as well.
