Methods and systems for determining device anomaly based on industrial internet of things

A system for determining a device anomaly based on an industrial Internet of things (IoT), wherein the system includes a user platform, a service platform, a device management platform, a device sensor network platform, and a device perceptual control platform, the device management platform includes a device management sub-platform and a management data center, and the device management platform is configured to:

• generate a data collection instruction based on a preset sampling rate through the device management sub-platform and send the data collection instruction to the management data center;
• obtain, based on the data collection instruction, operation data of at least one target device from a sensor general database in a device sensor network platform through the management data center, and partition and store the operation data based on a data source identification, the operation data being obtained by the device sensor network platform through a device perceptual control platform;
• determine a data anomaly degree for the at least one target device based on the operation data;
• in response to determining that the data anomaly degree satisfies a preset condition, determine an abnormal device based on the data source identification of the operation data;
• generate an anomaly warning instruction based on the abnormal device and the data anomaly degree corresponding to the abnormal device, and send the anomaly warning instruction to a user platform through a service platform;
• generate a sampling adjustment instruction based on the data anomaly degree and send the sampling adjustment instruction to the device sensor network platform to adjust the preset sampling rate at which the device sensor network platform obtains the operation data of the abnormal device through the device perceptual control platform;
• and
• generate a storage adjustment instruction based on the data anomaly degree and send the storage adjustment instruction to the management data center to adjust a size of a storage partition corresponding to the abnormal device in the management data center.
