Problems solved by technology

[0002] Some of the existing range hoods are based on the local algorithm processing of the real-time cooking video stream obtained by the camera to calculate the current concentration of soot and then adjust the speed of the range hood. Due to the time delay, the value corresponding to the recognition result often lags behind the current real oil fume situation or has a large error with the current oil fume situation

Embodiment 1

[0047] An embodiment of the present invention provides a method for controlling the speed of a range hood with multi-sensor fusion. The range hood includes an image acquisition device and a cooking parameter sensor, such as figure 1 As shown, the method may include S101-S104:

[0048] S101. Determine the reference speed of the hood at the current cooking stage according to the oil fume recognition result of the image acquisition device;

[0049] S102. Determine at least one reference rotational speed of the range hood in the current cooking state according to the cooking parameter detected by the cooking parameter sensor;

[0050] S103. Determine a milestone node in the cooking stage according to the cooking image acquired by the image acquisition device and / or the detection result of the cooking parameter sensor;

[0051] S104. Select the actual rotation speed of the range hood from a reference rotation speed and a reference rotation speed according to the milestone node.

Embodiment 2

[0082] An embodiment of the present invention provides a smoke machine with multi-sensor fusion, such as figure 2 As shown, including: an image acquisition device, a cooking parameter sensor, and a control circuit board, the control circuit board is provided with:

[0083] The recognition speed determination module is configured to determine the reference speed of the hood at the current cooking stage according to the oil fume recognition result of the image acquisition device;

[0084] A reference rotation speed determination module, configured to determine at least one reference rotation speed of the range hood in the current cooking state according to the cooking parameters detected by the cooking parameter sensor;

[0085] An identification module, configured to determine milestone nodes in the cooking phase according to the image collected by the image collection device and / or the detection result of the cooking parameter sensor;

[0086] The adjustment module is config...

Embodiment 3

[0088] This embodiment illustrates the process of adjusting the speed of the hood:

[0089] After the hood is turned on to automatically adjust the speed of the hood, information such as cooking images, cooking noise, and pot temperature are sent to the main control board CUP for analysis and processing, and the current corresponding hood gear is determined. The process of multi-sensor fusion speed regulation is as follows: image 3 As shown, at a certain moment, the cooking fume recognition algorithm quantifies the fume characteristic value according to the comparative analysis of the front and rear frame images to obtain a value reflecting the size of the fume and maps it to the minimum speed value that can completely absorb the fume of this size. Since this value is based on the image The algorithm inevitably has time delay. At the same time, other sensor parameter values ​​are used to correct the final rotational speed. In this embodiment, the parameters of cooking action,...

Abstract

The embodiment of the present invention discloses a multi-sensor fusion speed control method for a hood and a hood. The method includes: determining the reference speed of the hood at the current cooking stage according to the oil fume recognition result of the image acquisition device; according to the The cooking parameter detected by the cooking parameter sensor determines at least one reference rotational speed of the range hood in the current cooking state; the milestone node in the cooking stage is determined according to the cooking image acquired by the image acquisition device and / or the detection result of the cooking parameter sensor; according to the The milestone node selects the actual rotational speed of the range hood from the base rotational speed and the reference rotational speed. The speed adjustment of the hood is more real-time and more precise.
