Problems solved by technology

The shortcomings of this survey and measurement method mainly include: the content filled in the survey record card is not standardized, and it is easy to make mistakes; the positioning depends on artificial memory, and it is not convenient to correspond the site survey site of the project with the position on the plane section map; the manual workload Huge, especially for long-distance transmission line projects in densely vegetated areas, tree survey and measurement work needs to be carried out almost file by file, with as many as hundreds of record cards, and cross-sectional drawings of the entire line need to be edited, the workload of this manual method will be very large and highly error-prone and cause rework

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0030] Such as figure 1 As shown, a method for surveying and measuring transmission line trees based on a mobile terminal comprises the following steps:

[0031] Step (1), preparation of transmission line tree information materials; these transmission line tree information materials include vector data, raster data and text data.

[0032] details as follows:

[0033] According to the collected orthophoto image (DOM), digital line drawing (DLG) and line path data (DWG / DXF / TXT / CSV) of the line engineering area, set the forest information collection range, initially collect forest information, and generate db files; The orthophoto (DOM), digital line drawing (DLG) and line path data (DWG / DXF / TXT...

Abstract

The invention discloses a method for surveying and measuring power transmission line forest trees based on a mobile terminal. The method comprises the following steps: step (1), measuring data of transmission line forest tree information; step (2), performing on-site forest tree survey and measurement based on the mobile terminal; step (3), outputting a forest tree survey and measurement result. The method provided by the invention effectively avoids the occurrence of errors of the forest tree information due to manual writing of a forest tree survey and record card and manual marking of a plane cross section, greatly reduces manual operation, effectively reduces intensity of internal data processing work, realizes digital acquisition of the forest tree information and automatic outputting of results, and also saves paper to protect the environment.

Description

technical field [0001] The invention relates to a mobile terminal-based method for surveying and surveying trees of power transmission lines, and belongs to the technical field of engineering surveying in the subject of surveying and mapping. Background technique [0002] In the engineering survey and design of ultra-high voltage and ultra-high voltage transmission lines, it is necessary to investigate and measure the distribution of trees in a certain range on both sides of the center line of the line in the construction drawing design stage, and compile a "forestry survey record card" according to the survey and measurement results, and describe it in The line plane section diagram is used as important basic data for line safety distance design and technical and economic statistics. [0003] Forest tree survey and measurement is a special survey work in transmission line engineering. The national standard of the People's Republic of China "330kV~750kV Overhead Transmission...
