Cable shaft positioning method applicable for mobile terminal

Abstract

The invention discloses a cable shaft positioning method applicable for a mobile terminal. The method comprises the following steps: 1) classifying data to be displayed, and creating a data table for each category for data storage; 2) analyzing the data to obtain a topological relationship among the data, and then creating a topological relationship table to save the topological relationship; 3) finding out cable lines and cable shafts through searching according to road names or POIs; 4) according to coordinates of the cable shafts which are found out through the searching, drawing equipment on a geographic map through the OpenGL drawing method; and 5) generating a circle extending outwardly from a current position by 100 meters, searching for the cable shafts in the circle, and drawing the cable shafts on the map through the coordinates of the cable shafts. The method provided by the invention has the advantages that all the data is classified, and the required equipment can be rapidly found out through various searching methods and positioned, so that rapid navigation is achieved, and the patrol inspection and rush repair speeds are improved.

Description

technical field [0001] The invention relates to a method for assisting cable maintenance, in particular to a method for locating a cable well suitable for a mobile terminal. Background technique [0002] For the cables erected outside, regular maintenance is required, and timely repairs are required when problems arise. Generally speaking, most cables are buried underground, and the inspections are based on the experience of employees, which leads to some hidden or remote locations during inspections. Therefore, during daily maintenance or repair, it is necessary to check on the map. The traditional map is a paper map, which is not easy to store, and the paper is large in size, not easy to carry, and the amount of paper information records is limited. , which cannot fully reflect the state changes of cables and devices. Nowadays, some electronic maps are launched, but each device of the map uses a complete data to record, which takes up a lot of space and is not streamlined...
