摘　　要：本文主要介绍了利用PLC控制器采集实验室通风柜内部面风速,实现自适应(UBC)系统控制,并优化处理通风柜存在外界扰动时的面风速,包括面风速变化控制、通风柜操作门自动开启闭合、照明自动等。基于双闭环负反馈系统的实现方式,利用PID调节使通风柜面风量满足国家标准和通风柜变风量的需求。This paper mainly introduces the use of PLC controller to collect the surface wind speed inside the laboratory fume hood,realize the adaptive(UBC)system control,and optimize the processing of the surface wind speed when there is external disturbance in the fume hood,including the control of the surface wind speed change,the automatic opening and closing of the fume hood operation door,and the automatic lighting.Based on the realization of double closed loop negative feedback system,PID regulation is used to make the surface air volume of the fume hood meet the national standard and the variable air volume demand of the fume hood.
