Abstract

The invention discloses a laboratory ventilation abnormality detection method. The method comprises the steps of S1 acquiring real-time wind speed data in a ventilation pipeline in real time; S2 collecting the real-time wind speed data and constructing an abnormality identification model by using a plurality of wind speed data within a period of time; and S3, detecting the real-time wind speed data by utilizing a mathematical statistics method according to the abnormality identification model and judging whether the ventilation pipeline is abnormal or not. The invention further discloses a laboratory ventilation anomaly detection system which comprises a plurality of wind speed sensors, a sensing network and a background server and is used for realizing the laboratory ventilation abnormality detection method. According to the laboratory ventilation abnormality detection method and system provided by the invention, the abnormality identification model is constructed by using the mathematical statistics method to detect the laboratory ventilation condition, and the method is simple and easy to implement.

Description

technical field [0001] The invention relates to the technical field of laboratory safety, in particular to a method and system for detecting abnormality of laboratory ventilation. Background technique [0002] The laboratory is an important place for scientific research units to conduct practical teaching and scientific research, and has an important position and role in cultivating innovative talents and developing science and technology. During chemical experiments, toxic and harmful gases may be produced. If these harmful gases are not discharged from the laboratory in time, it may not only cause certain damage to the equipment, but also may pollute the air quality in the laboratory, which will affect the physical and mental health of the experimenters. cause some damages. In order to prevent laboratory workers from inhaling some harmful chemicals, the laboratory should have good ventilation conditions. Use a fume hood to vent some vapors, gases, and particles (smoke, s...
