1. An industrial Internet of things system for monitoring a collaborative robot, including a service platform, a management platform and a sensing network platform connected in sequence, wherein the management platform includes:
a first acquisition unit configured to obtain position data of a workpiece to be machined as first monitoring data through the sensing network platform; the first monitoring data being obtained through a machine vision recognition device configured in a target collaborative robot;
a matching unit configured to select, based on the first monitoring data, a benchmark working parameter matching the first monitoring data from a working parameter library, the benchmark working parameter being a benchmark that should appear in the target collaborative robot when the position data of the workpiece to be machined is in the first monitoring data in a normal working condition;
a second acquisition unit configured to obtain, via the sensing network platform, a working parameter of the target collaborative robot as second monitoring data when the target collaborative robot is machining the workpiece to be machined;
a comparison unit configured to compare the second monitoring data with the benchmark working parameter to determine a working state of the target collaborative robot;
a communication module configured to send the first monitoring data, the second monitoring data, the benchmark working parameter and the working state of the target collaborative robot to the user platform via the service platform for displaying to a user;
wherein
the working parameter library is configured with a correspondence of different monitoring data regions and benchmark working parameters;
the matching unit is further configured to:
traverse all the monitoring data regions in the working parameter library and select a monitoring data region where the first monitoring data is located; and
use the benchmark working parameter corresponding to the selected monitoring data region as a benchmark working parameter matching the first monitoring data; and
the comparison unit is further configured to:
calculate a residual allowable value based on a position of the first monitoring data in a corresponding monitoring data region, and generate a loss function based on the residual allowable value; and
compare the second monitoring data with the benchmark working parameter according to the loss function.
