Abstract

The invention provides a sensor data processing and cooperative prediction method based on edge calculation in the technical field of data processing and edge calculation. The method comprises the following steps: S1, establishing a scene model of a multi-sensor group, a multi-MEC server and an aggregation node; S2, the sensor group is configured with a data node with storage and communication functions to store record values of a plurality of past moments, and abnormal value detection and correction are carried out on data; S3, unloading the task data to the MEC server by the data nodes through bipartite graph matching; S4, performing clustering and fitting by the MEC server by using the received data, and sending the parameters to the aggregation node; and S5, receiving input data of theprediction task and performing comparative analysis on the data and the received parameters by the aggregation node; according to the method, the data node is established at the multiple sensors to unload the data cleaning task, and the data are predicted at the aggregation node, so that the accuracy and robustness are improved, and the time delay and energy consumption are reduced.

Description

technical field [0001] The invention relates to a sensor, in particular to a sensor data processing method, belonging to the technical fields of data processing and edge computing. Background technique [0002] In recent years, the development of wireless communication technology has endowed wireless sensor networks with strong data perception capabilities and broad application prospects, and has been widely used in environmental monitoring, medical health, military reconnaissance and other fields. These terminal devices also generate a large amount of data resources while working. Research on how to process and analyze these data will have a beneficial impact on economic life. [0003] Although the development of modern technology has made the quality of the sensor more reliable, in the actual data collection, there will always be some abnormalities in the process of data collection and transmission of the sensor equipment. In view of this, based on the characteristics of ...
