[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Embodiment 1

[0041] See also Figure 1-Figure 3 As shown, the present invention is an intelligent temperature control system based on an electric heated towel rack, comprising:

[0042] The towel rack image acquisition module uses a high-resolution camera to acquire the plane image of the electric towel rack. For example, a professional industrial camera with high resolution and excellent optical performance is used to capture every subtle detail, ensuring that the acquired image is of high quality, providing a reliable basis for subsequent analysis and processing. When acquiring the plane image of the heated towel rack, a high-resolution industrial-grade camera is used to ensure that the plane image of the electric towel rack can be clearly captured even in complex lighting environments. This module not only captures the overall layout, but also pays attention to the detailed texture, providing a high-quality data source for subsequent analysis;

[0043] The electric heating element marking module establishes a two-dimensional coordinate system on the towel rack, marks the positions of the electric heating elements on each crossbar, and obtains the position coordinates corresponding to the different electric heating elements on each crossbar of the electric heating towel rack according to the positions of the different electric heating elements on each crossbar of the electric heating towel rack in the two-dimensional coordinate system;

[0044] The electric heating element sorting number calibration module obtains the sorting number corresponding to each electric heating element on the electric towel rack according to the position sequence of different electric heating elements on each crossbar of the electric towel rack. The specific method is as follows:

[0045] The different electric heating elements on each crossbar of the electric towel rack are numbered in order from top to bottom according to the order of the crossbars on the electric towel rack, and then the positions of the different electric heating elements on each crossbar are numbered in order from left to right, so as to obtain the corresponding sorting number A of each electric heating element on the electric towel rack. i B r ; Where i refers to different crossbars on the electric towel rack, i=1, 2, ..., a, a refers to the number of corresponding crossbars on the electric towel rack, a≥1, r refers to different electric heating elements corresponding to different crossbars on the electric towel rack, i=1, 2, ..., b, b refers to the number of electric heating elements corresponding to a single crossbar of the electric towel rack, b≥1. Here, it should be noted that the number of electric heating elements corresponding to each crossbar on the electric towel rack is equal by default;

[0046] For example, when the sequence numbers of the two electric heating elements are A1B5 and A3B7 respectively, it means that the electric heating element with the sequence number A1B5 is located on the first horizontal bar from the top to the bottom of the electric towel rack and is the fifth electric heating element from the left to the right. Similarly, the electric heating element with the sequence number A3B7 is located on the third horizontal bar from the top to the bottom of the electric towel rack and is the seventh electric heating element from the left to the right.

[0047] The image contour acquisition module acquires the towel coverage area on the electric towel rack, and extracts the contour line of the coverage contour area according to the image of the towel coverage contour area on the electric towel rack. The specific method is as follows:

[0048] The towel coverage area on the electric towel rack is acquired through the contour acquisition unit, and the coverage contour area image is acquired. The contour of the towel coverage area on the electric towel rack is quickly and accurately extracted through the high-efficiency contour recognition algorithm built into the high-resolution camera, and a clear contour area image is generated. The above is an existing and mature technology, so no further description is made here;

[0049] Through the contour acquisition unit, the contour of the covered contour area is extracted according to the covered contour area image of the towel on the electric towel rack, and the contour is further refined to ensure the accuracy of edge detection and provide a precise boundary for subsequent distance calculation;

[0050] The start-up electric heating element calibration module determines and calibrates the start-up electric heating element by analyzing the coverage area of ​​the towel on the electric towel rack and the position coordinates of different electric heating elements on each crossbar of the electric towel rack. The specific method is as follows:

[0051] First, according to the coverage area of ​​the towel on the electric towel rack, the electric heating elements in the coverage area are obtained, and each electric heating element in the coverage area is marked as an electric heating element in the area;

[0052] The obtained coordinates of the intersections between the contour lines of the towel covered contour area and the horizontal bars on the electric towel rack are respectively corresponding to each other. According to the coordinates of the intersections between the contour lines and the horizontal bars on the electric towel rack and the coordinates of the remaining electric heating elements on each horizontal bar after removing the electric heating elements in the area, the distances between the coordinates of the intersections on each horizontal bar and the remaining electric heating elements on each horizontal bar after removing the electric heating elements in the area are calculated. The refracted electric heating elements are marked according to the distances. Although the refracted electric heating elements are not directly covered by the towels, they have an important influence on the heating effect because they are located close to the covered edge.

[0053] Specifically, S1: randomly select one of the horizontal bars on the electric towel rack as the target horizontal bar, and mark the coordinates of the intersection between the contour line of the towel coverage contour area and the target horizontal bar as ZA (ZAx, ZAy) and ZB (ZBx, ZBy), where ZA (ZAx, ZAy) is the coordinate of the intersection on the left side of the target horizontal bar, and ZB (ZBx, ZBy) is the coordinate of the intersection on the right side of the target horizontal bar;

[0054] S2: The coordinates of the remaining electric heating elements after the electric heating elements in the area are removed from the contour line of the covered contour area on the target crossbar are marked as Ev (Evx, Evy), and the distances between the remaining electric heating elements and the intersection coordinates ZA (ZAx, ZAy) and ZB (ZBx, ZBy) are marked as LAv and LBv, where v refers to the remaining electric heating elements after the electric heating elements in the area are removed from the contour line of the covered contour area on the target crossbar, and v is a positive integer, v≥1;

[0055] The electric heating elements whose values ​​in the distances LAv and LBv are less than the preset threshold value Y1 are marked as the refractive electric heating elements corresponding to the target crossbar, wherein the specific value of the preset threshold value Y1 is formulated by relevant personnel according to actual needs;

[0056] The distance calculation formula is:

[0057] , calculate the distance LAv between the intersection point ZA and the remaining electric heating elements Ev;

[0058] The distance calculation formula is:

[0059] ; Calculate the distance LBv between the intersection ZB and the remaining electric heating elements Ev;

[0060] S3: Repeat steps S1-S2 to obtain the refractive electric heating elements corresponding to each crossbar on the electric towel rack;

[0061] Obtain the heating element sorting numbers of the refraction heating elements corresponding to each crossbar on the electric towel rack and the heating elements corresponding to each area, mark them as start-up heating elements, and output the sorting numbers corresponding to the start-up heating elements;

[0062] The electric heating element start control module obtains the sorting numbers corresponding to the start electric heating elements, and starts and controls each corresponding electric heating element according to the sorting numbers corresponding to the start electric heating elements;

[0063] Image recognition technology is used to accurately obtain the coverage area of ​​the towel, and based on this, it is determined which electric heating elements need to be started. Through accurate analysis of the towel coverage area and the position of the electric heating elements, only the electric heating elements in the covered area and the surrounding refraction area are started, avoiding ineffective heating of the uncovered area. Targeted heating is performed according to the coverage and position of the towel to meet different usage scenarios and needs, solving the problem that the electric towel rack cannot flexibly adjust the heating strategy according to actual usage, and solving the problem of energy waste caused by overall uniform heating that may exist in the existing system. It can automatically determine and start the corresponding electric heating element according to the coverage of the towel, avoiding overheating and uneven heating, reducing safety risks, greatly improving user experience, improving energy utilization efficiency, reducing energy consumption, and extending the service life of the electric towel rack.

[0064] The above formulas are all dimensionless and numerical calculations. The formula is a formula for the most recent real situation obtained by collecting a large amount of data and performing software simulation. The preset parameters and thresholds in the formula are set by technicians in this field according to actual conditions.

[0065] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
