Embodiment

[0036] refer to figure 1 As shown, the method for planning the flight route of an aircraft patrolling a transmission line provided in this embodiment specifically includes the following steps:

[0037] S1. Import the road towers and site information to be inspected into the Google Earth software in batches in the form of longitude and latitude coordinates. The software batch processes and generates transmission line routes, and then forms a complete transmission line route map. The transmission line route diagram is based on different ground jurisdictions. Carry out division and identification (can be distinguished according to color), continue to add information such as the scope of each airspace jurisdiction unit, flight difficulty area and no-fly zone in the Google Earth software, and establish the panoramic information of the aircraft patrol route to realize the planning and drawing of the aircraft patrol flight route. Complete coverage of required information.

Abstract

The invention discloses a method of planning a flight course of a plane for patrolling an electric transmission line. The method comprises the following steps: step one, importing information of towers and stations to be patrolled into satellite map software in batches to form an electric transmission line route, adding patrolling flight full view information on electric transmission line route, and establishing a plane patrolling route full view information route; step two, determining temporary rising and landing points and flight waypoints of the temporary rising and landing points on the plane patrolling route full view information route; step three, analyzing the temporary rising and landing points and flight waypoints determined in the step two by a GA optimization algorithm, and prompting and assisting the operation to pick each temporary rising and landing point and flight waypoint of the rising and landing points so as to form a flight route; and step four, according to the direction of the flight route, the positions of the rising and landing points, and the performance indexes of the plane, obtaining a flight route having the shortest flight time and highest online rate. The method can obtain an optimal patrolling flight course, and the plane patrolling operation efficiency is improved.

Description

technical field [0001] The invention relates to route planning, in particular to a method for planning flight routes of aircraft patrolling transmission lines. Background technique [0002] Helicopter line patrol is a new general aviation flight service that has emerged in China in recent years. This type of flight is characterized by a large number of take-off and landing points for helicopters. At the same time, due to the dense and complicated distribution of power transmission lines, there are many flight routes and waypoints. Referring to the traditional general aviation flight route planning method, first sort out all the relevant waypoints and record the coordinates, plan the plane Cartesian coordinate system on the plane drawing, mark the waypoints, and generate the route by connecting the waypoints. This method is applied to the planning and planning of helicopter patrol route charts. There are problems such as heavy waypoint combing workload, cumbersome manual draw...
