基于光谱微型检测室互补温度控制器设计
|
摘要
为满足光谱微型检测室对温度快速稳定和精确控制的要求,设计了一种基于加热棒快速加热和帕尔贴(Peltier)稳定恒温的样品检测室气浴温度控制系统。系统以微控器为核心,集成模糊比例—积分—微分(PID)控制算法,实现了快速加热和精确恒温的互补功能。与现有的单一温度控制系统(水浴帕尔贴恒温控制)进行了对比实验测试,结果表明:检测室内样品反应体系的温度能够在5 min内精确稳定在(40±0. 3)℃内,缩短了温度控制时间,且温度控制的重复性好、准确度高,满足光谱类微型检测室对温度控制的要求。
In order to meet the requirements of fast stability and accurate control of temperature in spectral micro detection room,an air bath temperature control system for sample detection room with fast heating of heating rod and Peltier constant temperature is designed. The system takes the microcontroller unit as the core,and integrates the fuzzy proportional integral differential( PID) control algorithm,realize the complementary function of fast heating and precise constant temperature. The experiment compares the previous system of single temperature control,constant temperature control of water bath Peltier,and the test result shows that the temperature can be accurately controlled within( 40 ± 0. 3) ℃ in 5 min. It decreases much time of temperature control,and it has good repeatability and high accuracy of temperature control. So,it can meet the requirement of temperature control of the spectral micro-testing room.
