Embodiment Construction
[0024] The method for formulating the helicopter line patrol flight plan of the present invention rationally utilizes resources to save line patrol costs, better guides the safe operation of electric power production, and provides a new solution for the formulation and management of the helicopter line patrol flight plan for power transmission lines. The method will be explained in detail below in conjunction with the accompanying drawings and embodiments.
[0025] Such as figure 1 Shown, the formulating method of helicopter line inspection flight scheme of the present invention comprises steps:
[0026] Step 1, read the geographical environment information of the line to be inspected and its surroundings from the database;
[0027] Step 2, comprehensively consider the line inspection task, the helicopter range, the line to be inspected and the surrounding geographical environment, and determine the candidate temporary take-off and landing point;
[0028] Step 3, arrange and...

The invention discloses a method and a device for formulating a patrol flight scheme of a helicopter. The method includes the steps of firstly, taking full consideration of a line patrol task, the voyage of the helicopter, a patrol line and peripheral geographic environments and primarily selecting alternative temporary take-off and landing sites suitable for take-off and landing from the line to be patrolled; then listing all combination modes of the temporary take-off and landing sites and enabling each combination mode to serve as one site selection scheme; and finally enabling each site selection scheme to correspond to various line patrol path combination modes, finding one line patrol path combination mode with the shortest flight time as the line patrol flight scheme of each site selection scheme, or finding one site selection scheme with lowest flight cost and the line patrol flight scheme of the site selection scheme, and utilizing the line patrol flight scheme as the optimum line patrol flight scheme. Existing information is sufficiently used, the influence of all factors is comprehensively considered, and a permutation and combination process with the maximum calculated amount is completed by a computer, and accordingly, the optimum line patrol flight scheme can be accurately determined, staff involvement is reduced, decision-making period is shortened, the operating efficiency is improved, and the line patrol cost is reduced.
Description
technical field [0001] The invention relates to the technical field of high-voltage transmission line maintenance, and in particular to a method and device for formulating a helicopter line inspection flight plan. Background technique [0002] With the development of global positioning system (GPS), geographic information system (GIS), satellite map, and 3D simulation technology, the powerful spatial analysis capability of GIS is fully utilized, combined with the geographical distribution information of transmission lines, to realize the helicopter inspection of high-voltage transmission lines The detailed design and visual display of the flight plan become possible. [0003] The formulation of the helicopter line patrol flight plan mainly includes the determination of the temporary take-off and landing points and the line patrol path. Due to the high cost of helicopters, the line inspection cost of the established line inspection flight plan is an important factor to inves...
