摘　　要：基于传统量热仪技术升级换代要求,利用严格水套密封包围工艺结构设计了新型绝热式智能量热仪系统。采用ARM嵌入式技术开发了量热仪的定制触摸屏操作系统,利用ARM微处理器开发了系统的主控制器,采用具有高增益、高分辨率、低漂移特性的数模转换器,设计了量热仪的四路温度数据采集调理电路,采用分段式PID控制原理设计了量热仪的内、外筒水温自动跟踪控制算法,并对系统进行了测试实验。Based on the traditional calorimeter technology upgrading requirements, a new adiabatic intelligent calorimeter is de- signed by using rigorous process structure surrounded with a water jacket seal. Calorimeter custom touch screen operating system is developed by using ARM embedded technology, and the main controller is designed by using ARM microprocessor. The four tem- perature data acquisition processing circuit is designed by equipping with high-gain, high-resolution, low-drift DAC. The piecewise PID control theory is adopted to design the outer and inner cylinder water temperature automatic tracking control algorithm, and the experiments are made.
