Expressway electromechanical operation and maintenance management method based on time series data of Internet of Things

Abstract

The invention relates to the field of Internet of Things terminal management, in particular to a highway electromechanical operation and maintenance management method based on Internet of Things time series data, which comprises the following steps of: selectively decoding a coded data stream, and marking background interference frames according to a plurality of decoded frames so as to analyze the influence of background interference on coded data; the method comprises the steps of setting an interference identifier for coded data of an observation time domain segment, identifying abnormal coded data for unidentified coded data, synchronously determining a target reference time domain segment where the abnormal coded data is located, decoding coded data in the target reference time domain segment, obtaining a plurality of reference frames, and processing the reference frames. According to the method, the difference of the coded data collected by the Internet of Things terminals is considered, the rule constraint portraits aiming at different Internet of Things terminals are constructed, the multi-dimensional coded data are monitored adaptively, on the premise of ensuring the reliability, only partial decoding is carried out, and when the method is oriented to the large-range Internet of Things terminals, the computing resource consumption is reduced, and the monitoring efficiency is improved.
