In the glass production process, due to different raw material bin positions and different wear degrees in the use process of the feeding machine, the material mountain is easy to deviate, and the production quality of glass is influenced. Therefore, in order to secure the stability of glass production, the shape of the hill needs to be controlled. The shape of the material mountain can be monitored through image acquisition equipment to obtain a material mountain picture, wherein the image acquisition equipment can be a camera, and in order to enable the material mountain picture to be clearer, the image acquisition equipment can be a high-definition camera, namely, the image acquisition equipment can be a high-definition camera, the image acquisition equipment can be placed at the middle position of a material inlet gable of a kiln, the front end of the material mountain can be seen at the installation height, and the material mountain is generally between 2 meters and 3 meters on a material pool wall brick. In particular, as shown in fig. 2. The hill refers to a pile of raw materials that float on the surface of the glass without being completely melted into the glass kiln. Because of different raw material bin positions and different wear degrees in the using process of the charging machine, the material mountain is easy to generate deflection phenomenon, and therefore, the target shape can refer to the non-deflection material mountain front shape. The processor can acquire a first mountain image acquired by the high-definition camera, and after acquiring the first mountain image acquired by the high-definition camera, the processor can determine the change amount of the mountain according to the first mountain image. The processor can respectively determine the feeding speeds of the feeding machines according to the variation of the mountain so as to adjust the shape of the mountain to the target shape.
According to the technical scheme, the speed of each feeder is differentially controlled according to the variation of the material mountain, so that the phenomenon that the material mountain is inclined is avoided, the liquid flow variation of glass is in a normal range, and the glass quality is ensured.
Specifically, in one embodiment, determining the amount of change in the hill from the first hill image includes: acquiring a second mountain picture acquired by the image acquisition equipment, wherein the acquisition time of the second mountain picture is earlier than that of the first mountain picture; and comparing the first mountain picture with the second mountain picture to determine the change amount of the mountain.

The processor can shoot the video of the material mountain so as to obtain a corresponding material mountain video, wherein the shooting position can shoot from the front wall surface of the glass kiln. After the mountain video is obtained, the processor can perform frame extraction on the mountain video to obtain a plurality of mountain frame pictures. The processor can select a plurality of mountain pictures from a plurality of mountain frame pictures according to preset interval time, arrange the mountain pictures according to time sequence, and select one mountain picture from the mountain pictures as a first mountain picture in sequence after arranging the mountain pictures according to time sequence.
In one embodiment, the method further comprises: in the case that the mountain picture earlier than the first mountain picture is not present, the mountain variation amount of the first mountain picture is not analyzed; in the case that there is a mountain picture earlier than the first mountain picture, a previous mountain picture of the first mountain picture is acquired as a second mountain picture.
The change of the material mountain refers to the length change and the position change of the material mountain. After the mountain pictures are arranged according to the time sequence, the processor can not analyze the variation of the first mountain picture under the condition that the mountain picture earlier than the first mountain picture in time does not exist; under the condition that the mountain picture earlier than the first mountain picture exists, the processor can acquire the previous mountain picture of the first mountain picture as the second mountain picture, and at the moment, the processor can analyze the variation of the first mountain picture, namely, the first mountain picture can be compared with the second mountain picture so as to determine the length variation and the position variation of the mountain.
In one embodiment, the method further comprises: selecting a plurality of mountain pictures from a plurality of mountain frame pictures according to preset interval time, and then screening mountain pictures with picture time in the reversing period of the glass kiln from the plurality of mountain pictures as candidate mountain pictures; and sequentially selecting one material mountain picture from the alternative material mountain pictures as a first material mountain picture.

After the mountain video is obtained, the processor can perform frame extraction on the mountain video to obtain a plurality of mountain frame pictures. After a plurality of mountain pictures are selected from a plurality of mountain frame pictures according to preset interval time, the processor can screen the mountain picture with the picture time in the glass kiln reversing period from the plurality of mountain pictures as an alternative mountain picture, wherein the mountain picture in the glass kiln reversing period is free from interference of combustion flame, and the change quantity of the mountain can be accurately acquired later. After determining the candidate mountain picture, the processor may sequentially select one mountain picture from the candidate mountain pictures as the first mountain picture.
In one embodiment, the variation of the mountain includes a length variation and a position variation of the mountain, and determining the charging speed of each charging machine according to the variation of the mountain includes: determining the current value of each feeder according to the length variation and the position variation; generating a current control signal corresponding to each feeder according to the current value of each feeder; the feed rate of each feeder is controlled by a current control signal for each feeder.

Specifically, the processor may determine the current value of each feeder based on the length variation and the position variation, and in one embodiment, the current value may range from 0mA to 20mA. According to the change amount of the material mountain, the charging speed of the charging machine can be adjusted by adjusting the current value of the charging machine. Specifically, in one embodiment, determining the feeding speeds of the respective feeders according to the amounts of change in the material mountain, respectively, further includes: under the condition that the material mountain is inclined to the first feeder, increasing the current value of the first feeder to increase the feeding speed of the first feeder; in the case that the mountain is not deviated from the first feeder, the current value of the first feeder is reduced to reduce the feeding speed of the first feeder, or the current value of the first feeder is controlled to be constant so that the feeding speed of the first feeder is maintained to be constant. The processor can compare the first mountain picture with the second mountain picture to determine the length variation and the position variation of the mountain. After the length variation and the position variation of the mountain are obtained, the processor can respectively determine the speed of each feeder according to the length variation and the position variation of the mountain. In the case where the mountain is inclined toward the first feeder, that is, in the case where the amount of change in the mountain is large, the processor may increase the current value of the first feeder to increase the feeding speed of the first feeder. As shown in fig. 3A, in the case where the mountain is inclined to the No. 4 feeder, the feeding current value of the No. 4 feeder is increased to increase the feeding speed of the No. 4 feeder, and the No. 3 feeder may appropriately increase the feeding current value of the feeder, but the feeding current value of the No. 3 feeder should be smaller than the feeding current value of the No. 4 feeder, that is, the feeding speed of the No. 3 feeder should be smaller than the feeding speed of the No. 4 feeder. In the case where the mountain is not deviated from the first feeder, that is, the amount of change in the mountain is small and insufficient to change the shape of the mountain, the processor may decrease the current value of the first feeder to decrease the feeding speed of the first feeder. Alternatively, as shown in fig. 3B, in the case where the mountain shape is not changed, the processor may control the current value of the first feeder to be constant so that the feeding speed of the first feeder is maintained to be constant. That is, the current value of at least one of the No. 4 feeder, the No. 3 feeder, the No. 2 feeder, and the No. 1 feeder may be controlled to be unchanged.

The target shape refers to a non-skewed material mountain front shape. The change of the material mountain refers to the length change and the position change of the material mountain. The processor may obtain the amount of change in the glass level. Under the condition that the variation of the glass liquid level is obtained, the processor can respectively determine the feeding speed of each feeding machine according to the variation of the glass liquid level, the length variation and the position variation of the material mountain so as to adjust the shape of the material mountain to be a target shape, and the glass liquid level is controlled within a preset liquid level range, wherein the preset liquid level range can be a preset liquid level value +/-2 mm.
