Description

Technical Field

[0001] The present invention relates to the technical field of glass heating control, and in particular to a glass heating control method and device based on bilaterally symmetrical temperature prediction. Background Art

[0002] In the glass processing industry, tempered glass is widely used due to its excellent properties such as high strength, impact resistance, and wind pressure resistance. In order to produce high-quality tempered glass, the uniformity of its heating process is crucial. At present, horizontal roller heating equipment has become one of the mainstream production equipment for tempered glass. It sends the glass into the heating furnace through rollers and uses upper and lower heating control areas to heat the glass. However, in the existing heating control method, it is necessary to collect the temperature of multiple points in the left area and the right area of ​​the glass at the same time. The temperature collection process of multiple points not only depends on the collection point setting of the heating equipment itself, resulting in an increase in the structural complexity of the heating equipment, but also prone to data collection lags, making it difficult to improve the efficiency and accuracy of the heating temperature collection of the glass, thereby affecting the heating control process of the glass.

[0101] Embodiment 1

[0102] See also Figure 1 , Figure 1 : is a flow chart of a glass heating control method based on bilaterally symmetrical temperature prediction disclosed in an embodiment of the present invention. Optionally, the method can be implemented by a glass heating control device, which can be integrated in a heating furnace for glass heating, or a local server or cloud server for processing the glass heating control process, etc., which is not limited in the embodiment of the present invention. Figure 1 As shown, the glass heating control method based on bilaterally symmetrical temperature prediction may include the following operations:

[0103] 101. When the glass is on a roller in a heating furnace, determine the center line of the roller, and based on the center line, obtain position parameters corresponding to multiple collection points in a target area of ​​the glass.

[0104] In the embodiment of the present invention, the target area includes the left area of ​​the glass located on the left side of the center line or the right area of ​​the glass located on the right side of the center line, that is, for the glass placed in the roller of the heating furnace, the position parameters corresponding to multiple acquisition points in the left area of ​​the glass on the left side of the center line of the roller on the upper surface (or lower surface) of the glass parallel to the roller are obtained, or the position parameters corresponding to multiple acquisition points in the right area of ​​the glass on the right side of the center line of the roller on the upper surface (or lower surface) of the glass parallel to the roller are obtained. Further, based on the center line, combined with the size parameters and / or shape parameters of the glass, the position parameters corresponding to multiple acquisition points in the target area of ​​the glass can be obtained.

[0105] 102. Determine a regional symmetry relationship between a target region and a region to be predicted of glass corresponding to the target region.

[0106] In an embodiment of the present invention, the area to be predicted of the glass corresponding to the target area is the right area of ​​the glass symmetrical to the left area of ​​the glass, or the left area of ​​the glass symmetrical to the right area of ​​the glass, that is, when the aforementioned target area is the left area of ​​the glass, then the area to be predicted that needs to be temperature predicted later is the right area of ​​the glass symmetrical to the left area, and when the target area is the right area of ​​the glass, then the area to be predicted that needs to be temperature predicted later is the left area of ​​the glass symmetrical to the right area. Optionally, the regional symmetry relationship includes a vertical symmetry relationship or a central symmetry relationship, such as when the glass is a rectangular parallelepiped, the symmetry relationship between its target area and the area to be predicted includes a vertical symmetry relationship, and when the horizontal section of the glass is a parallelogram and the vertical section is a regular quadrilateral, then the symmetry relationship between its target area and the area to be predicted includes a central symmetry relationship.

[0107] 103. According to the position parameters corresponding to each acquisition point and the regional symmetry relationship, the point to be predicted corresponding to each acquisition point is determined from the region to be predicted.

[0108] In the embodiment of the present invention, for example, when the regional symmetry relationship between the target area and the area to be predicted of the glass corresponding to the target area is a vertical symmetry relationship, then a certain acquisition point (-4, 1) in the target area, its corresponding point to be predicted in the area to be predicted may be (4, 1); and when the regional symmetry relationship between the target area and the area to be predicted of the glass corresponding to the target area is a central symmetry relationship, then a certain acquisition point (-4, -1) in the target area, its corresponding point to be predicted in the area to be predicted may be (4, 1), and so on.

[0109] 104. Obtain the temperature parameters of each collection point, and predict the temperature parameters of all the points to be predicted based on the temperature parameters of all the collection points.

[0110] In the embodiment of the present invention, the collection process of the temperature parameters of all collection points can be implemented by a temperature collection module.

[0111] 105. Determine heating control parameters of the glass according to the temperature parameters of all the collected points and the temperature parameters of all the points to be predicted, and control the heating furnace to heat the glass according to the heating control parameters.

[0112] In the embodiment of the present invention, the heating control parameters of the glass are determined based on the temperature parameters of all the collected points in the target area and the temperature parameters of all the predicted points in the predicted area, so as to realize the heating control process of the glass. Optionally, the heating control parameters may include one or more of heating power control parameters, heating temperature control parameters, heating position control parameters, roller movement control parameters, etc.

[0113] It can be seen that the implementation of the embodiment of the present invention can predict the temperature parameters of the corresponding area through the temperature parameters of a single area, thereby realizing the heating control process of the glass based on the temperature parameters of the two areas. There is no need to collect the temperature of the left and right areas of the glass at the same time, which improves the temperature collection efficiency and accuracy of the glass, and then improves the heating control accuracy of the glass; at the same time, it is also conducive to simplifying the structure of the glass heating equipment.

[0117] The temperature parameters of all the points to be predicted are predicted according to the device parameters of the first heating device, the device parameters of the second heating device and the temperature parameters of all the acquisition points.

[0118] In this optional embodiment, it can be understood that according to the device parameters of the first heating device (such as a thermocouple) and the temperature parameters of all the collection points, the device condition and temperature relationship corresponding to each collection point are analyzed, and then the temperature parameters of each point to be predicted are predicted according to the device condition and temperature relationship corresponding to each collection point and the device parameters of the second heating device corresponding to the area to be predicted. Among them, the device parameters of the first heating device include the device operating power parameters of the first heating device, and the relative position parameters between the first heating device and each collection point; and the device parameters of the second heating device include the device operating power parameters of the second heating device, and the relative position parameters between the second heating device and each point to be predicted. In addition, the device parameters of the first heating device and the device parameters of the second heating device can also include device type parameters.

[0119] It can be seen that this optional embodiment can predict the temperature parameters of all points to be predicted based on the device parameters of the first heating device corresponding to the target area, the device parameters of the second heating device corresponding to the area to be predicted, and the temperature parameters of all the collection points. In this way, while simplifying the structure of the glass heating equipment, it is beneficial to improve the prediction rate and accuracy of the temperature parameters of the points to be predicted, and further help to improve the reliability and accuracy of determining the heating control parameters of the glass, thereby facilitating rapid and accurate heating control of the glass.
