摘要:
基于半导体制冷片(Thermo Electric Cooler,TEC)设计了一种高精度控温电路系统,本文详细介绍了TEC的选型方法,设计并实现了以单片机为核心的硬件电路采用PID 软件控制算法优化温控参数?在实验中选择较大热负载紫铜块作为控温对象进行实验验证?实验结果表明: 在室温23℃的情况下,紫铜块的控温范围为(-10~40℃)控温精度高达0.01℃
Abstract:
This paper designed a high-precision temperature-control circuit system based on TEC.Introduction was made to the selectionmethod of TEC,realizing a hardware circuit based on singleˉchip and using PID software control algorithm to optimize parameters.In experiment?choosing the higher thermal load copper block as the temperature control object to do the test verification.The result shows when the ambient temperature is 23℃,the temperature control range of the copper block is (10~40℃).The temperature control precision can be up to 0.01℃.
