Abstract

The invention discloses a range hood oil fume concentration visual detection system with a visible light filtering function, which comprises a range hood main body, a visual detection module and a main control unit. The visual detection module is electrically connected with the range hood main body and the main control unit. The visual detection module is provided with a light filtering part and avisual detection part. Natural light cannot penetrate through the light filtering part, and infrared rays penetrate through the light filtering part. The light filtering part is assembled on the visual detection part, and the visual detection module faces the corresponding stove area. The visual detection part is used for acquiring lampblack image information. The main control unit is used for processing the lampblack image information acquired by the visual detection part and analyzing and calculating the current lampblack concentration. According to the invention, the filtering part which is made of the polycarbonate material and is impermeable to natural light and infrared rays is assembled on the visual detection module, so that the transmittance of the infrared light is enhanced while the interference of the natural light is filtered, and the accuracy and universality of the detection of the oil fume concentration of the range hood are improved.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a visual detection system for oil fume concentration of a range hood with a visible light filtering function. Background technique [0002] With the continuous development and improvement of our country's national economy, oil fume pollution in the catering industry has become a major problem of urban environmental pollution. Short-chain aldehydes, ketones, and polycyclic aromatic hydrocarbons (PAHs) are carcinogens of various toxic chemical components. These fumes not only pollute the air and aggravate the smog weather, but if the human body is inhaled for a long time, its immune function will decline, leading to respiratory system lesions, Blood genetic lesions and lung tissue lesions, a large number of studies have shown that people who have been exposed to oil fume for a long time are as likely to suffer from respiratory diseases as long-term smokers, and can also cause a v...
