Description

Technical Field

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

[0002] On the climbing section of the conveyor belt of the steel plate transverse cutting unit, the sheet with a large oil content slips, as Figure 1 shown. This is a common phenomenon, which not only affects production efficiency, but may also cause injury to personnel lifting the sheet. At present, due to the difficulty of reducing the oil content of the square steel coil in the safety technical transformation of the equipment, the inclination angle and length of the climbing section conveyor belt cannot be changed, and the problem of chip dropping caused by adding anti-slip patterns on the conveyor belt surface affects the surface cleanliness of the finished sheet. There is no anti-slip measure in the existing equipment, and the slipping problem cannot be effectively solved. 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 the common general knowledge.

[0004] Many anti-slip conveying systems have now been developed. After a large number of searches and references, it is found that the existing anti-slip conveying systems are like the system disclosed in the publication number 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 by using the anti-slip strips, and to avoid the situation that the rising angle of the conveyor belt is too large, which will cause the sand and gravel materials to slide. And when using the distributing plate to perform fixed-point blanking of the materials, the fixation between the anti-slip strip and the conveyor belt can be released to avoid the problem of the anti-slip strip conflicting with the distributing plate. However, this system is not suitable for the conveying of metal sheets and still easily shows a sliding phenomenon. Summary of the Invention
