摘　　要：首先对大型超市变风量中央空调系统进行总体设计,并将视频图像处理技术运用到大型超市中央空调节能控制的研究中,提出了一种基于帧间差分与背景差分结合的运动目标检测算法计算局部区域的人流密度,根据局部区域的人流密度利用PLC来控制温度和新风量,实现了系统节能,达到了"风跟人走"的效果。The paper designs a VAV central air conditioning system in large-scale supermarket. And video image processing technology is applied into the study. In addition, it comes up with a new background difference algorithm combined frame difference method and background difference method. Taking advantage of that algorithm , occupant density in the district can be concluded. Temperature and fresh air volume can be adjusted according to the occupant density.
