A method and system for transmitting and compressing information transmission at the edge of the Internet of Things on a power transmission and transformation inspection platform

Abstract

The invention discloses a transmission and compression method and system for information transmission and compression on the edge of the Internet of Things on a power transmission and transformation inspection platform, which acquires measurement information collected from equipment related to operation inspection, fits the measurement information through a cubic spline fitting function model, and outputs Cubic spline fitting function, using the cubic spline fitting function to calculate the predicted output at the current moment, using the mutation detection function model to judge whether the predicted output at the current moment and the actual measurement at the current moment are mutations, if a mutation occurs Then send the actual measured value at that moment to the master station, otherwise, do not send it. Advantages: It can effectively detect the sudden change of measurement data, and meet the requirements of abnormal signals of the attention equipment in the transportation inspection; it meets the data compression requirements of the sudden change detection, reduces the bandwidth demand and traffic consumption as much as possible, and provides a comprehensive solution for the ubiquitous power system. Union provided support.

Description

technical field [0001] The invention relates to a method for self-adaptive information transmission and compression of Internet of Things edge information of a power transmission and transformation operation inspection platform, and belongs to the technical field of power system automation. Background technique [0002] In recent years, large-scale IoT equipment collection and data analysis methods represented by State Grid's "Ubiquitous Internet of Things" and China Southern Power Grid's "Digital Southern Network" are aimed at improving equipment availability, prolonging its service life, and reducing operation and maintenance. It provides a technical guarantee to ensure the healthy and stable operation of the power grid. [0003] Among them, in the power transmission and transformation inspection business, in order to detect the possible hidden faults and risks of the equipment and the environment in which it is located, and carry out preventive maintenance, it is necessar...

Problems solved by technology

[0005] Traditionally, the first method is to increase the frequency of monitoring information uploading. This method greatly increases the data bandwidth occupation and power consumption of IoT devices, so it is not widely adaptable; the second method is to filter the uploaded signals, mainly When the threshold exceeds the monitoring signal, it will be uploaded, but this situation is not conducive to the detection of equipment abnormalities such as the increase in the frequency of intermittent signal disturbances
