Problems solved by technology
[0003] However, these IoT devices don't always work perfectly, and as a result, the IoT data they generate often has anomalies
Once the device fails, the application program in the IoT device will limit the transmission time, place and content, which will easily cause data loss or outliers

The present invention provides a method for filling missing data of the Internet of Things, including: step S1, the clustering node obtains the node information set of the Internet of Things device from the Internet of Things database, and aggregates the devices according to the node information set of the Internet of Things device class, get the device clustering result, and send it to the filling node; step S2, the filling node receives the device clustering result, and reads the missing data to be filled from the Internet of Things database, traverses each piece of missing data, analyzes and extracts the The node information corresponding to the missing data record, and obtain the same-cluster node set in the clustering result of the Internet of Things equipment; Step S3. Filling the node According to the same-cluster node set, obtain the complete data corresponding to the same-cluster node in the Internet of Things database, and The missing data and the complete data are clustered to obtain the data clustering results, and the missing data are filled according to the clustering results.
Description
technical field [0001] The present application relates to the technical field of data filling, in particular to a method and system for filling missing data in the Internet of Things. Background technique [0002] With the gradual development and improvement of the Internet of Things technology, almost all smart devices can be interconnected through the network to form a huge Internet of Things. According to estimates, there will be as many as 10 billion Internet-connected IoT devices in 2020, including new-generation products such as automobiles, industrial automation equipment, implantable medical devices, wearable devices, and smart homes, and the next-generation 5G network has already begun to operate in a certain area. Deployed in these areas and is expected to bear most of the traffic generated by the above equipment. [0003] However, these IoT devices don’t always work perfectly, and as a result, the IoT data they generate often has anomalies. Once the device fails...
