Description

Unmanned plane UAV automatic control system

Technical field

The invention relates to unmanned plane UAV(Unmanned Aerial Vehicle) technical field, and relate to unmanned plane UAV automatic control system especially.

Background technology

Along with the high speed development of infotech, global position system GPS (Global Positioning System) and high resolving power are taken photo by plane the application of sensor in aeroplane photography, photogrammetric measurement technology is had great development, becomes the novel practical technology that integrates remote sensing, remote control, telemetry and computer technology.After entering 21 century, this technology is progressively applied to civilian and industrial circle from military field especially, and the concept of " digitalized city " and " the digitizing earth " that propose in the recent period, this technology proceeds to civilian imbody just.

Photogrammetric measurement technology is exactly carry out digitizing, two-dimentional three-dimensional process to the Aerial Images gathered in flight course, obtains spatial information or the status information of various terrain object, to meet the information requirement of people to various embody rule.Now, photogrammetric measurement technology applies many aspects such as ten military affairs, Disaster Assessment, ecological Studies, communications and transportation, mapping, city planning widely; In electric system, photogrammetric measurement technology also starts to be applied, and wherein polling transmission line is an important application direction.

Transmission line of electricity is responsible for the important duty of electric power transfer, is the basic work effectively ensureing transmission line of electricity and equipment safety operation thereof to the regular visit of transmission line of electricity.Along with China's rapid development of economy, UHV (ultra-high voltage), Large Copacity, long distance transmission line are built more and more, existing electric transmission line channel resource becomes and is becoming tight day, and transmission line of electricity is more and more away from city and main traffic artery, and the geographical environment that line corridor passes through is more complicated.The operating type that Traditional Man is patrolled and examined, is more and more subject to the restriction of natural conditions, cannot meet actual needs.Adopt helicopter polling transmission line mode to have efficiently, quick, reliable, cost is low, not by advantages such as regional impacts, become the important way of China's polling transmission line.The Main way that " it is main that helicopter is maked an inspection tour, and manual patrol is auxiliary " is the current high pressure of China, supertension line is patrolled and examined.

Long-play finds to there is a lot of potential safety hazard, that is:

(1) in daily helicopter routing inspection work, the working method of helicopter routing inspection mainly contains: range estimation, observation of use instrument and instrument automatically detect and combine, main working method is range estimation, comprise and observing by telescope, or watch afterwards photography, shooting record image to judge line fault and hidden danger, obviously, this mode efficiency is low, affect greatly by subjective and objective factor, measuring accuracy is difficult to guarantee, and be auxiliary owing to being manual patrol, the automaticity detected is reduced greatly;

(2) in order to protect the personal safety of the personnel of taking photo by plane, the distance between general helicopter and electric wire generally has 20 ~ 30 meters far away, and distance so far away increases camera undoubtedly and measures the difficulty of taking photo by plane between object, can have influence on the sharpness of image sometimes;

(3) for adopt the image of helicopter aerial photography be all generally taken photo by plane by camera after be stored in certain storer, then by video recording research afterwards, doubt region is analyzed, in order to ensure that accuracy also needs secondary even repeatedly to take sometimes, add testing expenses undoubtedly;

(4) in helicopter routing inspection process, the image information that circuit patrolled and examined in the equipment records such as visible ray digital camera, camcorder and infrared thermography can be carried, these image informations contain essential characteristic and the running status of transmission line of electricity, do not have the function of real-time analysis;

(5) adopt helicopter routing inspection to adopt the risk of range estimation mode itself very high, easily the accidents such as the person or hardware occur; Add the danger of test;

(6) due to the singularity of helicopter routing inspection, the distortion that Aerial Images occurs in imaging process, fuzzy, distortion or be mixed into noise, cause the decline of picture quality, this makes the process in later stage bother very much;

(7) due to the replacement in the four seasons in 1 year, the physical environment in transmission of electricity corridor and landforms are constantly changed, the various images gathered are along with the change of environment, background becomes very complicated, contrast reduces, target jamming increases, simultaneously, other natural features, also the complexity of image background is made to deepen further with culture, make the extraction of target under complicated nature background owing to not having implementation and identify very difficult, the Objective extraction under complex environment is a technical problem underlying measuring of present Helicopter System and bottleneck;

(8) need the device category of monitoring a lot of in polling transmission line, the type of fault is also varied, so, need analyze according to video recording and calculate distinct device and fault type in later stage diagnostic procedure, and according to number location of fault as roughly estimated, then adopt artificial visually examine's secondary to determine.
