Description

Technical Field

[0001] The present invention relates to the field of electric digital data processing, and particularly to a real-time diagnosis and feedback system for the deviation degree of the conveying trajectory of sheet materials based on edge computing. Background Art

[0002] On the climbing section of the conveyor belt of the steel plate transverse cutting unit, sheet materials with a large oil content slip, as Figure 1 shown. This is a common phenomenon, which not only affects production efficiency but may also cause injuries to personnel lifting the plates. Due to problems such as the difficulty in reducing the oil content of square steel coils during safety technical transformation, the inclination angle and length of the conveyor belt on the climbing section cannot be changed, and adding anti-slip patterns on the conveyor belt surface brings problems of chip dropping and affects the surface cleanliness of the finished sheet materials, etc., the existing equipment has no anti-slip measures and cannot effectively solve the slipping problem. Therefore, a system is needed to monitor the conveying trajectory and take feedback measures.

[0003] The foregoing discussion of the background art is only intended to facilitate the understanding of the present invention. This discussion does not recognize or admit that any of the materials mentioned is part of common general knowledge.

[0004] Many anti-slip conveying systems have been developed. After a large amount of retrieval and reference, it is found that existing anti-slip conveying systems are like the system disclosed in CN119683257A. These system methods generally include: after the discharge end of the material conveying device rises at a certain angle, anti-slip strips can be automatically set on the surface of the conveyor belt to improve the conveying capacity of the conveyor belt and avoid the situation where the conveyor belt rises at too large an angle, causing sliding of sand and gravel materials. And when using the distributing plate to perform fixed-point blanking of the materials, the fixation between the anti-slip strips and the conveyor belt can be released to avoid the problem of the anti-slip strips conflicting with the distributing plate. However, this system is not suitable for the conveying of sheet materials made of metal and still easily exhibits sliding phenomena. Summary of the Invention

[0005] The object of the present invention is to propose a real-time diagnosis and feedback system for the deviation degree of the conveying trajectory of sheet materials based on edge computing in view of the existing deficiencies.

When a slight sliding phenomenon is detected, the resistance is promptly increased to prevent affecting the next sheet metal. When left-right imbalance is detected, by controlling the current, the side with slower sliding has less resistance, temporarily increasing the sliding speed. After the two sides are rebalanced, the current is restored, and the sheet metal no longer slides, realizing automatic restoration of the balanced state and improving the conveying work efficiency.
