Intelligent control system for laboratory ventilation

Abstract

The invention discloses an intelligent control system for laboratory ventilation. The intelligent control system comprises a collecting unit, an analyzing unit, a ventilation unit and a control unit. The collecting unit is used for collecting laboratory internal image information. The analyzing unit is used for obtaining the laboratory internal image information collected by the collecting unit, conducting similarity contrast between the laboratory internal image information and preset image information and outputting a similarity contrast result S. The ventilation unit is used for conducting ventilation on the interior of the laboratory according to an instruction of the control unit. The control unit is in communication connection with the collecting unit, the analyzing unit and the ventilation unit, obtains the similarity contrast result S through the analyzing unit, compares S with a preset value and controls the ventilation unit to act according to the comparison result instruction.

Description

technical field [0001] The invention relates to the technical field of laboratory intelligent ventilation, in particular to an intelligent control system for laboratory ventilation. Background technique [0002] The environmental requirements of the laboratory are generally relatively high, and providing a stable environment for the experimenter is also crucial to the accuracy of the experimental data. At present, many experiments are carried out in fume hoods or specific operating cabinets, although these experiments It is carried out in a fume hood or a specific operating cabinet, but it is inevitable that some gases will overflow and flow into the laboratory. If the gas exchange in the laboratory is not performed in time, it will easily cause some unhealthy gases to accumulate in the laboratory. The health of laboratory operators is affected, and if the laboratory is not ventilated for a long time or the ventilation is not thorough, it will still lead to poor air quality ...

[0002] The environmental requirements of the laboratory are generally relatively high, and providing a stable environment for the experimenter is also crucial to the accuracy of the experimental data. At present, many experiments are carried out in fume hoods or specific operating cabinets, although these experiments It is carried out in a fume hood or a specific operating cabinet, but it is inevitable that some gases will overflow and flow into the laboratory. If the gas exchange in the laboratory is not performed in time, it will easily cause some unhealthy gases to accumulate in the laboratory. The health of laboratory operators is affected, and if the laboratory is not ventilated for a long time or the ventilation is not thorough, it will still lead to poor air quality inside the laboratory, which is also harmful to the health of operators in the laboratory Therefore, it is necessary to ventilate the interior of the laboratory according to the actual operation process of the personnel in the laboratory, improve the efficiency of ventilation and ventilation inside the laboratory, exchange the air in the laboratory with the outside air, and ensure that the laboratory The quality of the internal air creates a comfortable and healthy experimental operating environment for the operators in the laboratory, and improves the effect of the experimental operation on the basis of ensuring the health of the operators in the laboratory
