Description

technical field

The invention belongs to the technical field of transmission line survey, and relates to a plane section analyzer, in particular to a portable transmission line plane section analyzer.

Background technique

At present, the survey of transmission lines is usually carried out according to the following steps:

(1), the staff surveys the terrain data with a GPS measuring instrument or an optical measuring instrument on site;

(2) After the survey, input the data on the measuring instrument to the computer;

(3) Use the transmission line plane section analysis software installed on the computer to process the surveyed data to generate a transmission line plane section diagram.

The current transmission line analysis software can only be analyzed and processed based on the category of personal computer (ie PC platform) due to the large memory usage. Even if it is a portable laptop computer, it is inconvenient to take it to the field with complex terrain to analyze the measurement data. Therefore, the current general method is to bring the data surveyed by the GPS measuring instrument or optical measuring instrument in the field back to the room, and then transmit the data to the computer for analysis to generate a horizontal cross-sectional diagram of the transmission line. But there are some problems with this:

(1) The plan view of the current path cannot be obtained at the survey site, resulting in inaccurate judgment of the path plan;

(2) After obtaining the horizontal section diagram of the transmission line in the room, due to the large delay in rework, the optimal path is often not re-surveyed and compared, but the tower type is adjusted to meet the current measurement section, which is likely to cause cross-span safety margins Tension, more waste of towers, high cost of lines and other phenomena.
