Abstract

The invention provides equipment and a method for detecting and controlling the state of a show window of a fume hood. The equipment for detecting and controlling the state of the show window of the fume hood comprises human body detection equipment and a fume hood show window control device. The fume hood show window control device controls opening and closing of a fume hood show window according to a human body detection result of the human body detection equipment. The human body detection equipment comprises a fume hood monitoring visual angle camera, a frame difference detector and a full-feature target detector; The frame difference detector judges an image foreground and preliminarily identifies a human body by comparing pixel values of a background frame and a video frame in a video frame image for matching; the full-feature target detector adopts a lightweight deep neural network to carry out human body recognition on the video frame image again. The problems of long time delay and high false detection and omission ratio of human body recognition detection are solved, and the monitoring efficiency of automatically controlling the state of the shop window of the ventilation cabinet is improved.

Description

Technical field [0001] The present invention relates to the field detection and control technology of a ventilated cabinet, and more particularly to a device and a method of detecting and controlling a fan-winding condition. Background technique [0002] The safety management of the laboratory has always been a concern of the majority of research institutions. One of the main reasons for some safety accidents in recent years is that when the laboratory personnel leave the laboratory, there is no closet window, and some of the equipment in the ventilator have long heated, resulting in serious accidents such as fire. At present, there is still little study on the condition of the wind-free cabinet window, and more relevant research is about the detection of the door and window state. If the infrared induction should detect the opening and closing of the car window, the opening and closing state of the home window, etc. With the rapid development of artificial intelligence, the open...
