摘要
本文介绍了基于ADuC841单片机和半导体加热制冷片的小型温度控制系统设计。本设计采用半导体加热制冷片作为温度控制的执行部件,温度传感器DS18B20进行温度检测并提供反馈信号,在控制器单片机上实现增量式PID控制算法。本设计的应用为实现快速、精确的小型温度控制系统提供了一种体积小、功耗低、经济有效的解决方案。
A design of benchtop temperature control system based on MCU ADuC841 and semiconductor heating-refrigerating chips is introduced in this paper. In this design, semiconductor heating-refrigerating chips are employed as executive component for temperature control. Temperature sensor DS18B20 is used to detect the temperature and provide feedback. Incremental PID algorithm is implemented on the controller MCU. This design and development indicates a small size, low power consumption and efficient operation solution to realize a fast and precise benchtop temperature control system.
