Embodiment Construction
[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0034] The method for obtaining the coordinates of transmission line towers, the flow chart of the method is as follows figure 1 shown. This method is based on computer technology, traverse adjustment calculation technology, and GPS measurement technology. When it is specifically applied to the power grid, taking the 220kV and above voltage level transmission lines in the southern power grid area of Hebei Province as an example, a total of 283 transmission lines are involved. Each transmission line The acquisition methods of the pole and tower coordinates all adopt the method described in the present invention. Taking a power transmission line as an example below, the method of the present invention for obtaining the coordinates of all poles and towers on the power transmission line will be described.
[0035] A. By consulting the...

The invention discloses a method for acquiring a transmission line tower coordinate. In the method, based on a computer technology, a lead adjustment calculation technology and a GPS measurement technology, one transmission line is taken as one control measurement lead; information, such as an apparatus, a measuring method, a horizontal angle, a horizontal distance and the like, is obtained through data mining. A few field GPS measuring points are reasonably arranged. The GPS is used to acquire national coordinates of the field GPS measuring points. Computer software is controlled and measured to calculate the national coordinates of the whole towers. Precision assessment is performed and measurement precision can be guaranteed. Compared to the current general method for acquiring the national coordinates of the tower through the GPS measuring method, by using the method of the invention, cost is low; a working efficiency is high; labor intensity is low; personnel needed in the method is few; quality is reliable; it is convenient for popularization and application; economic benefits and social benefits are remarkable.
Description
technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a method for obtaining coordinates of transmission line poles and towers through a computer. Background technique [0002] Power grid GIS is a computer system that manages topographic maps, remote sensing images, and transmission lines, substations and power plants with GIS theory and methods. Spatial and attribute data, it serves for the planning, survey and design, construction and operation of transmission networks. Data is the blood of a GIS system, and in the entire life cycle of a GIS system, data accounts for about 70% of the entire investment. Grid data is the core of grid GIS, and grid spatial data is the basis for attribute data positioning. [0003] The transmission line is composed of a series of poles, towers and wires connected between the poles and towers. The national coordinates of the poles and towers are the basis for the spatial positioning of t...
