System for precise intelligent inspection of power transmission line multi-rotor unmanned aerial vehicle and method thereof

Abstract

The invention relates to the technical field of unmanned aerial vehicle controlling, and particularly to a system for precise intelligent inspection of a power transmission line multi-rotor unmanned aerial vehicle and a method thereof. The precise intelligent inspection system of the power transmission line multi-rotor unmanned aerial vehicle comprises a control terminal and a flight platform which is connected with the control terminal. For settling problems of easy getting lost, high photographed picture archiving workload and low efficiency in performing overhead power transmission line equipment fault searching by a multi-rotor unmanned aerial vehicle now, the invention provides the system for precise intelligent inspection of the power transmission line multi-rotor unmanned aerial vehicle, a method thereof and a control terminal.

Description

technical field [0001] The present invention relates to the technical field of unmanned aerial vehicle control, and more specifically, relates to a transmission line multi-rotor unmanned aerial vehicle fine intelligent inspection system and method thereof. Background technique [0002] With the rapid development of power grid construction, the scale of the power grid is gradually expanding, and the coverage of transmission lines is also increasing, and most of them operate in the suburbs and wilderness. They are often affected by changes in bad weather, geographical conditions, and operating conditions, which inevitably lead to crises. Power grid safety and reliability Operation failure. Regular inspections of transmission lines can detect abnormalities that threaten line safety in time, and regular defect searches can eliminate hidden dangers, strengthen the power grid's ability to fight against severe natural disasters, ensure safe and stable operation, and bring long-term...

AI Technical Summary

Problems solved by technology

However, there are the following technical defects in the first solution: (1) Overhead transmission lines are mostly located in suburban and mountainous areas, and inspection work is extremely difficult in seasons such as spring and autumn rainy and summer heat, so manual inspection conditions are difficult and inefficient; (2) Overhead transmission Iron towers are often very high, and it is difficult to accurately judge the line equipment manually using a telescope, resulting in many missed defects, and the inspection quality cannot be guaranteed; (3) Once a suspected defect is found, it is necessary to apply for a work ticket, conduct a tower inspection, and take pictures Records, this not only increases the workload of line workers, but also has the safety risk of falling from high places when climbing the iron tower

However, the second solution has the following disadvantages: (1) The use of helicopter flight platforms requires high inspection costs, making it difficult to promote and use them in most provincial and prefecture-level line operation and maintenance units; (2) the use of helicopter flight platforms requires operation and maintenance The unit is equipped with professional pilots, professional operation and maintenance support teams, and a large number of logistics support such as aircraft transport vehicles, making patrol operations difficult; (3) patrolling in the air with manual hand-held telescopes for continuous observation, the operators are very difficult, the work is poorly standardized, and the quality is difficult to guarantee

However, the third scheme still has the following defects: (1) Most of the overhead power transmission lines are located in the suburbs and mountainous areas. Therefore, under normal circumstances, the inspectors control the multi-rotor drones beyond the visual range. It is easy to get lost, and it is difficult to fly to the designated target tower for inspection operations; (2) There are many overhead transmission line equipment, if each one is photographed and recorded, and there is no corresponding intelligent matching image and renaming software, the inspection personnel will have a huge workload and efficiency Low, the accuracy of defect finding is difficult to guarantee the problem
