Intelligent wind speed regulation range hood based on background modeling

Abstract

The invention provides an intelligent wind speed regulation range hood based on background modeling. A range hood body is provided with a vision imaging module, a processing module and a wind speed control module. The vision imaging module conducts continuous imaging on a target area and transmits video stream information of imaged pictures to the processing module. The processing module conductsprocessing to obtain smoke grade information and transmits the smoke grade information to the wind speed control module. The wind speed control module controls a wind speed regulator to regulate the wind speed according to the smoke grade information transmitted by the processing module. The vision imaging module is provided with a camera, an infrared supplement light and a relay. The processing module obtains the current smoke area of the target area and the corresponding concentration of the current smoke area through a background model frame difference method and then conducts smoke grade quantitative processing according to the smoke concentration to obtain the smoke grade information. The power of the intelligent wind speed regulation range hood based on background modeling can be automatically regulated, and the kitchen environment can be purified. On one hand, electric energy can be effectively saved; and on the other hand, manual operation can be reduced, and the user experience can be improved.

Description

technical field [0001] The invention relates to the technical field of kitchen fume treatment, in particular to an intelligent wind speed adjustable range hood based on background modeling. Background technique [0002] The kitchen is one of the necessary configurations at home, and the effect of kitchen fume treatment directly affects people's quality of life. Traditional range hoods control the wind speed mainly through physical buttons. This method realizes the range hood wind speed adjustment 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...

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
