Line acquisition method and device based on Internet positioning

Abstract

The invention relates to the technical field of line information acquisition, and discloses a line acquisition method and device based on Internet positioning, and the method comprises the following specific steps: employing the distribution simulation of a line to establish a tree diagram line distribution diagram, and enabling the nodes in the tree diagram line distribution diagram to be line branch points, a branch line is arranged between two nodes in the tree diagram line distribution diagram, and the length of each branch line is determined; according to the line acquisition method and device based on Internet positioning, the tree diagram line distribution diagram is established through line simulation, and the IP address is set at each fulcrum position of the line, so that the positioning range of the branch line can be narrowed, the positioning precision of the branch line can be improved, and the positioning accuracy of the branch line can be improved by acquiring electromagnetic waves in the line. And inflection points of abnormal changes of electromagnetic waves and time for electromagnetic wave acquisition modules at two ends of the line to acquire the inflection points of the electromagnetic waves are recorded, so that the position of a fault point relative to a line node is accurately calculated.

Description

technical field [0001] The invention relates to the technical field of line information collection, in particular to a line collection method and device based on Internet positioning. Background technique [0002] When the power grid system is running, it is necessary to monitor and manage the operation status of each line in the power grid, so it is necessary to collect the operating parameter information of the line. The fault problem of the line is discovered in time, so as to respond in time. When the line fails, it is necessary to determine the location of the fault. [0003] The existing method for judging and locating fault points of a line is to collect traveling waves, process them, and determine the location of the fault points according to the wave speed of the processed traveling waves. At the same time, it is necessary to install multiple monitoring terminals in the line. The process of judging and locating the fault point of the line is relatively complicated....

Problems solved by technology

[0003] The existing way of judging and locating the fault point of the line is to collect the traveling wave, process the traveling wave, and determine the position of the fault point according to the wave velocity of the processed traveling wave. At the same time, multiple monitoring terminals need to be installed in the line. The process of judging and locating line fault points is relatively complicated. When the monitoring terminals work together, there will be a certain response time difference. Therefore, the accuracy of judging and locating line fault points is not high. high
