The invention provides an edge heterogeneous
Internet of Things operation and maintenance
chassis data processing method and
system. The method comprises the following steps: firstly, according to the types of the multi-source heterogeneous terminals, formulating a unified
data acquisition scheme, defining a unified acquired
data format, respectively managing and executing a
data acquisition task of each multi-source heterogeneous terminal by adopting an asynchronous multi-
thread scheduling mechanism, and acquiring and generating corresponding acquired
original data; and performing
standardization processing on the collected
original data in the normal sampling state to generate a multi-source collected
data set. And then, according to the type of each multi-source heterogeneous terminal, for the corresponding multi-source acquisition
data set, calculating a standardized anomaly
score, performing weighted comprehensive
processing, generating a comprehensive anomaly
score, and determining an anomaly level according to the comprehensive anomaly
score. And finally, correspondingly matching the exception level of the multi-source heterogeneous terminal with a preset local protection strategy, executing a local exception protection action based on a matching result, recording exception information and reporting exception alarm information to a remote center platform.
