Intelligent oil fume exhaust ventilator wind speed adjustment method and intelligent oil fume exhaust ventilator wind speed adjustment apparatus

Abstract

The invention discloses an intelligent oil fume exhaust ventilator wind speed adjustment method, which comprises: collecting an image below an oil fume exhaust ventilator; detecting the edge of the image to obtain the target area of the stove in the image; treating the target area of the stove in the image or treating the video stream of the target area of the stove to obtain smoke information; generating and outputting a wind speed adjustment command to a wind speed adjustment device according to the smoke area and the smoke level; and adjusting the wind speed of the oil fume exhaust ventilator by the wind speed adjustment device. The invention further discloses an intelligent oil fume exhaust ventilator wind speed adjustment apparatus using the intelligent oil fume exhaust ventilator wind speed adjustment method, wherein the intelligent oil fume exhaust ventilator wind speed adjustment apparatus comprises a camera, a control chip and a wind speed adjustment device, wherein the camerais used for collecting the image below the oil fume exhaust ventilator, and the camera and the wind speed adjustment device are respectively connected to the control chip. According to the present invention, with the method and the apparatus, the stove area is imaged, and the obtained image is treated to obtain the smoke area and the smoke level, such that the smoke concentration can be accurately judged, and the wind speed of the oil fume exhaust ventilator can be accurately adjusted.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to an intelligent range hood wind speed adjustment method and device. Background technique [0002] At present, the control of the wind speed of the traditional range hood is mainly realized through physical buttons, and this method realizes the adjustment of the wind speed of the range hood through manual manipulation. This method has many disadvantages in actual operation: 1. The smog level is not clearly distinguished, and the human operation often adjusts the high power to prevent the occurrence of large smog, thus causing a great waste of power resources; 2. Artificially adjusting the range hood wind speed will have Latency affects the operating experience. [0003] The existing automatic speed range hood has achieved a great improvement in the performance of the range hood. Most of them are based on non-visual smoke detection devices, which can judge the smoke concentrati...

This method has many disadvantages in actual operation: 1. The smog level is not clearly distinguished, and the human operation often adjusts the high power to prevent the occurrence of large smog, thus causing a great waste of power resources; 2. Artificially adjusting the range hood wind speed will have Delay, affecting the operating experience

[0003] The existing automatic speed range hood has achieved a great improvement in the performance of the range hood. Most of them are based on non-visual smoke detection devices, which can judge the smoke concentration near the smoke detection device. Determine the range of smoke, and it is not sensitive to water vapor, so the maximum power is used for smoke with a small range but high concentration, resulting in false alarms, false alarms, false alarms, etc., and the detection effect on water vapor is poor

Therefore, it is inaccurate to adjust the fan speed of the range hood based on this kind of smoke detection
