The present application claims priority to Chinese Patent Application No. 200911400463.7, entitled "Reservoir Detection Method, Apparatus, Cooking Apparatus, and Computer-Readable Storage Medium", filed on December 22, 2017, the entire contents of which are incorporated herein by reference. This is incorporated herein by reference.

Technical field

Background technique

In the related art, the storage device develops a reserve detection function in order to enhance the user experience when storing materials, and the specific working principle of various reserve detection schemes is as follows:

(1) a plurality of optical sensors having different horizontal positions are disposed on the inner wall of the housing portion of the storage device, and the optical sensor detects the brightness value in the housing portion, wherein the optical sensor covered by the material detects that the brightness value in the housing portion is low, The optical sensor not covered by the material has a higher brightness value in the housing, and the upper surface position of the material is determined according to the sudden change of the brightness value.

(2) The set-up detecting component comprises a driving member and an optical sensor disposed on the outer side wall of the accommodating portion, and the driving member drives the optical sensor to continuously move between the top and the bottom of the accommodating portion, thereby continuously detecting any horizontal position in the accommodating portion. The brightness value is moved between the top and the bottom of the housing by the optical sensor, and likewise, the upper surface position of the material is determined based on the sudden change in the brightness value.

However, the above two reserves detection schemes have the following technical defects:

(1) When there is no additional light source in the housing, if the ambient light brightness value is low, the sudden change point of the brightness value of the optical sensor is not obvious, which results in a large measurement deviation;

(2) When an additional light source is provided in the housing, if the light source is kept emitting visible light during the detection of the reserve, the power consumption of the storage device is increased.

Summary of the invention

The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

Accordingly, it is an object of the present invention to provide a method of detecting a reserve.

The difference between the brightness of the material covering area and the brightness of the material-free area is small, and therefore, the brightness sudden change point may be judged to be inaccurate, that is, the upper surface position of the material is inaccurate, and it is precisely by the fill light. The radiation increases the brightness of the material-free covering area in the accommodating portion, thereby improving the brightness difference between the material covering area and the material-free covering area, which is favorable for detection accuracy.

The value is also recorded as Ym.
