Claim 8:
9. A control method of an industrial Internet of Things (IoT) for industrial data processing, which is used in a service platform, a management platform, and a sensing network platform that interact in turn, wherein the sensing network platform includes a sensing network general platform and a plurality of sensing network sub-platforms;
the method comprising:
the sensing network sub-platforms receiving image information of a product when a process operation of a production line ends as a first image data; each of the sensing network sub-platforms receiving the first image data corresponding to different process operation;
the sensing network sub-platforms identifying first feature information of the first image data, and correcting, according to the first feature information and baseline feature information, the first image data to form second image data;
the sensing network sub-platforms sending the second image data to the sensing network general platform;
the sensing network general platform receiving the second image data, and sorting the second image data according to the process operation of the production line to form a first image database;
the sensing network general platform sending the first image database to the management platform;
the service platform calculating a difference of corresponding data in a first image difference data of different products as a second image difference data, including:
determining a time series based on the first image difference data, wherein the time series is a series of generation time of each product arranged in an order of time;
performing a stationarity test on the time series;
calculating a statistical data of the time series based on a result of the stationarity test;
determining the second image difference data; and
sending the second image difference data to the management platform;

the management platform identifying a difference between adjacent second image data in the first image database as the first image difference data;
the management platform generating, according to the first image difference data, a control parameter of a production line device, and correcting the control parameter as a first parameter, and issuing the first parameter to the production line device through the sensing network platform; and
the management platform sending the first image database and the first image difference data to the user platform for display through the service platform.
