Abstract

The present disclosure provides an Industrial Internet of Things for early warning of descending function fault of equipment, comprising a management platform, wherein the management platform is configured to perform following operations including: obtaining execution status of at least one production task executed by equipment in a preset time period; based on the execution status of the at least one production task, judging whether the equipment has a descending function fault; in response to the equipment having the descending function fault, issuing an early warning and repairing the equipment.

First claim

What is claimed is:

1 . An Industrial Internet of Things for early warning of descending function fault of equipment, comprising a management platform, a user platform, a service platform, a sensor network platform, and an object platform, wherein
the user platform, the service platform, the management platform, the sensor network platform, and the object platform interacting in sequence from top to bottom, the user platform is configured as a terminal device, the service platform is configured as a first server cluster, the management platform is configured as a second server cluster, the sensor network platform is configured as multiple groups of gateway servers or multiple groups of smart routers, the object platform is configured as a smart manufacturing equipment in a production line that performs manufacturing, the first server cluster includes a first total server and multiple first sub-servers, the second server cluster includes a second total server and multiple second sub-servers, both the service platform and the management platform adopt a front sub-platform arrangement, and the sensor network platform adopts an independent arrangement; the front sub-platform arrangement means that the corresponding platform is provided with a total platform and multiple sub-platforms, the multiple sub-platforms store and process data of different types or different receiving objects sent by a lower platform respectively, the total platform aggregates, stores, and processes data of multiple sub-platforms, and transmits the data to an upper platform, the independent arrangement means that the sensor network platform uses different sub-platforms for data storage, data processing and/or data transmission for data of different object platforms, the total platform is configured as the first total server or the second total server, the multiple sub-platforms are configured as the multiple first sub-servers or the multiple second sub-servers; and the management platform is configured to perform following operations including: obtaining execution status of at least one production task executed by the equipment in a preset time period; based on the execution status of the at least one production task, judging whether the equipment has a descending function fault, including:
obtaining, by a sub-platform of the management platform, a recognizable data file corresponding to a single-piece manufacturing parameter from a sub-platform of the sensor network platform, wherein the single-piece manufacturing parameter at least includes total time-consuming data of the manufacturing equipment during single-piece manufacturing, the single-piece manufacturing parameter is uploaded to a corresponding sub-platform of the sensor network platform by the sub-platform of the sensor network platform, the recognizable data file refers to a data file that the management platform recognizes, and the recognizable data file is obtained by converting the single-piece manufacturing parameter data based on the sub-platform of the sensor network platform;
extracting, by the sub-platform of the management platform, the total time-consuming data based on the recognizable data file;
calculating, by the sub-platform of the management platform, a time difference between two adjacent total time-consuming data in sequence according to a time sequence of the single-piece manufacturing based on the total time-consuming data;
sorting, by the sub-platform of the management platform, all time differences in sequence according to the time sequence of the single-piece manufacturing to form a time difference data set;
sending, by the sub-platform of the management platform, the recognizable data file and the time difference data set to the total platform of the management platform;
after receiving the time difference data set, analyzing, by the total platform of the management platform, on descending function fault based on the time difference data set, and
when an analysis result is normal, deleting the time difference data set and waiting for the analysis of a re-uploaded time difference data set by the total platform of the management platform; or
when the analysis result is abnormal, merging the recognizable data file, abnormal result data, and the time difference data set into analysis data, and uploading the analysis data to a corresponding sub-platform of the service platform by the total platform of the management platform;
in response to the equipment having the descending function fault, issuing an early warning and repairing the equipment, including: receiving, by the total platform of the management platform, a self-repair sub-instruction from the corresponding sub-platform of the service platform; and obtaining, by the total platform of the management platform, an instruction code data package corresponding to the self-repair sub-instruction, wherein
the instruction code data package is pre-stored in the total platform of the management platform,
the self-repair sub-instruction is sent by the total platform of the service platform,
the self-repair sub-instruction is determined based on an overhaul instruction by the total platform of the service platform,
the overhaul instruction is sent by the user platform,
the overhaul instruction is determined based on grade information by the user platform,
the grade information is determined based on abnormal result data of packaged data by the total platform of the service platform,
the packaged data is sent by the corresponding sub-platform of the service platform,
the packaged data includes an abnormal time node, the abnormal result data, and the time difference data set, and
the abnormal time node is obtained based on the recognizable data file by the corresponding sub-platform of the service platform;
associating, by the total platform of the management platform, the instruction code data package with the self-repair sub-instruction and sending, by the total platform of the management platform, the instruction code data package and the self-repair sub-instruction to the sub-platform of the management platform; and sending, by the sub-platform of the management platform, the instruction code data package and a recognizable configuration file corresponding to the self-repair sub-instruction to a corresponding object platform through the sub-platform of the sensor platform, wherein
the self-repair sub-instruction is configured to cause the corresponding object platform to execute self-repair at execution time by calling the instruction code data in the instruction code data package based on the self-repair sub-instruction,
the recognizable configuration file refers to a configuration file that is recognized by the corresponding object platform,
the recognizable configuration file is obtained by converting the self-repair sub-instruction based on the sub-platform of the sensor platform, and
the execution time is determined by the total platform of the service platform based on the overhaul instruction corresponding to different execution times.

2 . The Industrial Internet of Things of claim 1 , wherein after the total platform of the management platform receives the time difference data set, and the total platform of the management platform performing analysis on descending function fault based on the time difference data set includes:
after the total platform of the management platform receives the time difference data set, the total platform of the management platform choosing to calculate a difference between absolute values of two adjacent time differences in sequence according to the time sequence of single-piece manufacturing; when the difference is negative, and the number of consecutive negative values of the difference is greater than a threshold set by the total platform of the management platform, the total platform of th
