1. A control system of an Industrial Internet of Things for sheet workpiece processing comprising a service platform, a management platform, and a sensor network platform, connected in sequence, wherein the management platform performs operations to:
obtain a first target image on a production line through the sensor network platform, wherein the first target image is an image of a target sheet workpiece under a fixed focal length condition;
perform sharpness analysis on the first target image to generate a sharpness matrix and calculate a tilt direction and a tilt angle of the target sheet workpiece as tilt data according to the sharpness matrix;
input the tilt data and the first target image into a tilt correction model and receive a second target image output by the tilt correction model, wherein the second target image is an image of the target sheet workpiece in a completely horizontal state;
perform calibration and identification on the second target image, generate horizontal adjustment data and rotational adjustment data corresponding to the second target image, and calculate tilt adjustment data according to the tilt data;
send the horizontal adjustment data, the rotational adjustment data, and the tilt adjustment data to the production line through the sensor network platform to adjust a bearing mechanism of the target sheet workpiece; and
send the horizontal adjustment data, the rotational adjustment data, and the tilt adjustment data to a user platform through the service platform for display;
wherein the management platform further performs operations to: search for sharpness elements with a sharpness lower than a standard value and with a same sharpness in the sharpness matrix as same degree sharpness elements; connect the same degree sharpness elements into a straight line in the first target image, and calculate the tilt direction according to the straight line; and obtain a plurality of straight lines connected by a plurality of sets of same degree sharpness elements in the first target image, and calculate the tilt angle according to position relationships between the plurality of straight lines and the tilt direction.
