Range hood automatic control method and system based on multi-sensor fusion

Abstract

The invention relates to a range hood automatic control method and system based on multi-sensor fusion. The range hood automatic control method comprises the steps: real-time temperature data, real-time humidity data and real-time oil smoke concentration data nearby a range hood are obtained, and control coefficients, for a range hood air damper, of the temperature, the humidity and the oil smokeconcentration are calculated; according to all the obtained control coefficients, for the range hood air damper, of the temperature, the humidity and the oil smoke concentration, the influence coefficient, for the range hood air damper, of the environment air condition is obtained, and according to the identification result of whether a human body is located nearby the range hood or not, the finalinfluence coefficient, for the range hood air damper, of the human body is obtained; and a preset gear threshold value aiming at the gear of the range hood air damper is set according to the final influence coefficient, for the range hood air damper, of the human body, and according to the preset gear threshold value, the air damper gear corresponding to the range hood is obtained. According to the range hood automatic control method and system, influences of the temperature, the humidity, the oil smoke concentration and the human body factor on gear control of the range hood are sufficientlyconsidered, and through fusion processing of the various environment factor influences, the gear of the range hood air damper is real-timely and accurately controlled.

Description

technical field [0001] The invention relates to the field of smoke machine control, in particular to an automatic control method and system for smoke machines based on multi-sensor fusion. Background technique [0002] The automatic control of the hood means that the hood (or hood) stores the hood concentration data reported by the hood sensor, and automatically analyzes and integrates the collected hood concentration data to accurately complete the scene recognition. , and then the smoke machine makes corresponding information processing according to different identified scenes, so as to provide accurate range control of the smoke machine. [0003] In the current field of hoods, almost all hoods are based on the fume concentration data collected by the fume sensor to realize the linkage between the fume and the hood. However, there is a big error in the linkage between the oil fume and the hood: for example, when the user boils water, a large amount of water vapor will be ...

AI Technical Summary

Problems solved by technology

However, there is a big error in the linkage between the oil fume and the hood: for example, when the user boils water, a large amount of water vapor will be generated, which cannot be discharged, and a large amount of accumulated water vapor will seriously affect the windshield of the hood. Gear position control; In addition, other gases brought by the influence of wind will also cause false triggering of the range hood, making it impossible for the range hood to accurately identify the scene in which it is located, and thus it is difficult to accurately control the wind of the range range hood. stalls

It can be seen that the traditional solution of only relying on oil fume to realize the linkage control of the wind gear of the hood has been difficult to meet the actual operation needs of users.
