摘　　要：该研究立足安全工程与控制工程专业的结合,研制了基于PID自动控制原理的隧道火灾智能空气幕防烟实验教学平台,可满足两个专业多门课程的理论与实验教学需求。该平台能形象地展示自动控制原理与传统空气幕相结合实现复杂火灾场景下智能防烟功能的效果。基于该平台的教学能够将理论知识、实验操作和数据分析相结合,提升了相关课程实验的质量和效果,提升了学生的创造思维和探索能力。[Objective]Traditional experimental teaching is usually conducted only for a single course,ignoring the inherent,intrinsic connection of multiple courses and resulting in fragmented knowledge teaching,which wastes teaching and space resources.In reality,many issues are complex,and it is difficult for a single discipline to solve them comprehensively.Thus,multidisciplinary knowledge and methods must be thoroughly applied.In safety engineering,smoke control requires knowledge and theory from disciplines such as fluid dynamics,fire dynamics,and fire engineering.Therefore,interdisciplinary theory integration teaching is an innovative method to meet the needs of modern society and scientific and technological development,which has important educational significance and application value.[Methods]On the basis of the combination of safety engineering and control science engineering,this study developed a tunnel fire intelligent air curtain smoke control experimental teaching platform.It was based on the principle of proportional–integral–derivative(PID)automatic control,which met the theoretical and experimental comprehensive teaching needs of multiple professional courses in both majors.By adjusting the PID parameters,the response characteristics of the system under different settings can be observed.The individual roles and combined effects of the proportional,integral,and derivative controllers can be understood.Deeper insights into fire dynamics and fluid dynamics can be obtained by varying the fire heat release rate(HRR)and analyzing phenomena such as the flame tilt angle and temperature distribution.By adjusting the jet angle and velocity of the air curtain,changes in smoke spread can be observed,facilitating an understanding of the effects of air curtain smoke control.[Results]This research found that when appropriate PID parameters were set(kp=0.1,ki=0.01,kd=0.05),the system not only maintained stability but also responded rapidly to environmental changes,achieving excellent control performance.The temperatu
