Embodiment Construction

[0027] To make the object, technical solution and advantages of embodiments of the present invention more clear, the following will be combined with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be further described.

[0028] A line patrol table used for power line patrol Figure 3 Dimensional positioning coding method, the specific technical parts are as follows:

[0029] 1. Two-dimensional positioning coding part: After the line-line map is divided into a less complex multi-level shared base grid, it can first be encoded in two dimensions by the row and column method. That is, it is encoded sequentially from left to right, from bottom to top. Due to the different shapes and sizes of blocks, their coding is uniformly stipulated according to the following principles:

[0030] (1) Each block is encoded with its lower left corner as the base point, while following the principle of first ...

Abstract

The invention discloses a three-dimensional positioning coding method for a line inspection chart, which belongs to the field of inspection. It encodes each block with its lower left corner as the base point, and at the same time follows the principle of first down and then left, first determine the horizontal coordinates, and then determine the vertical coordinates, and distinguish common distinctions according to the area of ​​​​each divided block and its base point Its position, just can carry on coding smoothly. It assigns a fixed number to each grid unit, one-to-one correspondence, cannot be repeated, and must be systematic. This kind of coding is for the three-dimensional positioning coding method of the line patrol chart, which can uniquely definitely represent every line in every block.

Description

Technical field [0001] The present invention relates to the field of power inspection, specifically, to a three-dimensional positioning coding method of a line patrol table diagram. Background [0002] "Electricity is the first of the industry", without the rapid and stable development of the electric power industry, there will be no sustained, steady and high-speed growth of the national economy. [0003] The role of transmission lines and their surrounding equipment in the transmission system is very critical. [0004] In practice, due to their long-term exposure to nature, power lines and equipment not only bear the role of normal mechanical loads and power loads, but also withstand external forces such as pollution, lightning strikes, strong winds, floods, landslides, subsidence, earthquakes and bird infestations. A variety of factors will promote the aging, fatigue, oxidation and corrosion of the components on the line, if not found and eliminated in time, it may develop int...
