Orthoimage data-based power equipment power transmission line generation system

Abstract

The invention provides an orthoimage data-based power equipment power transmission line generation system, which comprises an unmanned aerial vehicle, a detection device, a positioning device, an acquisition device, an obstacle avoidance device and a processor. The detection device, the acquisition device and the obstacle avoidance device are all arranged on the unmanned aerial vehicle and are used for identifying obstacles or objects on an advancing route of the unmanned aerial vehicle; the positioning device is used for positioning the position of the power transmission frame so as to guide the direction of the unmanned aerial vehicle; the acquisition device acquires power transmission lines of two adjacent power transmission racks and is used for determining the direction of a wiring diagram of power equipment; and the obstacle avoidance device is used for detecting obstacles at the front end of the operation direction of the unmanned aerial vehicle so as to recognize the obstacles and adjust the advancing direction of the unmanned aerial vehicle. The unmanned aerial vehicle is adopted to perform simulation estimation based on the terrain environment, and the power transmission frame and the power transmission line direction are determined by combining gradual fitting of the positioning device.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a power equipment transmission line generation system based on orthophoto image data. Background technique [0002] Transmission line inspection is an important means to ensure the safe and reliable operation of transmission lines, and one of its most important tasks is tower inspection. According to the power industry standard overhead transmission line operation regulations, the main objectives of data collection during the inspection process are 1) tower and foundation: whether the tower body and cross arm are damaged, corroded, deformed, whether the foundation and guy wire are intact; 2) wire and ground wire: yes No broken strands, damage, looseness, hanging foreign objects; 3) Insulators: whether the porcelain insulators are damaged, cracked, or burnt; Fittings and accessories: whether the body of the fittings is deformed, rusted, burnt, or cracked; whether the a...

Problems solved by technology

[0003] For example, the prior art of CN102780177B discloses a method for collecting inspection data of overhead power lines based on flying robots. Traditional manual inspection consumes a lot of manpower and material resources, has high safety risks, low inspection efficiency, and inconvenient data recording and retrieval.

At present, the machine inspection method used in actual production in China is mainly manned helicopter inspection. According to the technical guidelines for helicopter inspection of overhead transmission lines, helicopter inspection has high requirements for inspection personnel, high safety risks in the inspection process, and large investment in equipment. , the inspection procedure is complex

Existing technologies such as KR102247664B1, EP2418327B1, and US08423796B1 were discovered after a large number of searches. Due to the scarcity of land resources, local planning departments required that power lines be routed according to reserved power corridors in order to avoid disorderly routing of power lines, resulting in multi-loop The power lines of different voltage levels are routed in the same corridor, and the distance between power lines is small

It cannot meet the actual planning needs. At the same time, due to the small spacing of high-power transmission power lines, it is difficult to realize crossing power lines passing through the corridor power lines by drilling and crossing at the same time, and the small spacing of power lines is likely to cause short-circuit triggering of power lines security risks

At the same time, if the number of transmission towers is increased, the investment will increase, the occupied area will also increase, and the connection will be more complicated

[0004] In order to solve the common problems in the field that it is impossible to predict the power transmission line in advance, the labor intensity of manual inspection is high, some areas cannot be manually repaired, the direction of the wiring line cannot be estimated, and the evaluation cannot be performed online, etc., the present invention is made
