The traditional ring network cabinet distribution network monitoring technology has poor noise reduction ability,which results in distortion of remote monitoring results.Therefore,a new smart ring network cabinet distribution network remote comprehensive monitoring technology is studied.This technology compensates for missing data by analyzing the transmission loss of the monitoring data of the intelligent ring network cabinet distribution network in free space;based on the basic monitoring methods of the monitoring technology,the dynamic networking method of the remote monitoring technology is comprehensively designed,and the monitoring network structure is reset;Autoregressive moving average model(ARMA model)is used to simulate the monitoring noise waveform signal,calculate the attenuation characteristics of the background noise,and reduce the monitoring noise through a reliable transmission algorithm.The experimental results show that compared with the traditional monitoring technology,the researched monitoring technology has stronger noise reduction capability and higher signal-to-noise ratio of the obtained monitoring signal.It can be seen that this technology meets the latest requirements of monitoring technology for remote integrated monitoring of the distribution network of intelligent ring network cabinets.
