Description
Technical field
The invention belongs to a kind of auxiliary systems and method for training on maintenance, more particularly to answer augmented reality
With.
Background technique
All purpose aircraft ownership in China's is few at present, and professional navigation maintenance company is still seldom.Although nearly 20 years China
It doubles within all purpose aircraft quantity every 10 years, but compared with navigation develops the more mature U.S. in the world, China's navigation aircraft
Quantity and the flight time it is still less (23.1 ten thousand frame of United States Aircraft quantity in 2009, flight 28,000,000 hours).Simultaneously as
China's General Aviation manufacturing industry falls behind relatively, and country's navigation aircraft is mostly from external import, so there is also navigation aircraft types
Feature many and diverse, type is small.Existing more than 1000 frame is general and personal aircraft in contain 80 different types of machines.China is logical
The characteristics of boat, limits the development of the navigation maintenance service enterprise of China's profession.
Domestic General Aviation industry is grown rapidly in recent years, but the part of General Aviation is also in China Civil Aviation Legal System at present
Unsound not perfect, there are many blank, lack specific and actual guidance to country's navigation maintenance management.It is difficult to look at home
Maintenance company to profession provides service for general aviation aircraft, forces domestic navigation enterprise in order to make aircraft certification, must not
It does not spend high cost to establish maintenance system and provides necessary service for the aircraft of oneself.This is flying General Aviation enterprise
It is usually unable to do what one wishes in operation after machine purchase.The shortage for specializing in navigation maintenance company seriously limits China's navigation
Development.
According to the requirement of civil aviaton's regulation, the mature maintenance personal of culture one needs 5 years or more the time, a set of maturation is established
Maintenance system then take more time.Therefore, the most of navigation enterprises runed at present, even if establishing the maintenance system of oneself
System, due to fund, experience etc., also can be only done basic maintenance, aircraft overhaul, Engine Overhaul etc. also needs Aircraft Production quotient
It completes.It is costly, time-consuming, seriously affect navigation enterprise's normal operation.
The machine substantial amounts that are related to of navigation maintenance, and the maintenance process of each different machine and method exist compared with
Big difference.Navigation, which has begun, has arrived the advanced Technology application such as electronic documentation, digitized measurement in navigation maintenance process.
However in navigation maintenance technique training link, it is limited that duration is practiced in the maintenance of student, practices scene and is difficult that existing number is completely covered
Huge machine is measured, existing maintenance practices scene and has been difficult to adapt to the navigation market in repair service need of China's rapid growth completely
It asks.
For large aircraft public transportation companies since staff size is huge, most of application has CCAR-147 qualification, mechanism
The training of company's maintaining unit is held a concurrent post, training organization either facility, data, program and personnel are fairly perfect and neat
Entirely.And the enterprise that opens the navigation or air flight at present, due to the limitation of personnel, cost and technology, the investment in training system is all in low-level shape
State leads to following situations occur:
1), start-up is not professional enough
Navigation enterprise in CCAR-145 maintaining unit, exist: 1., a people supervisor or part-time supervisor training the case where,
2., the personnel of the non-civil aviaton's specialty background of recruitment serve as training director's post.Since training director's professional knowledge is insufficient, the effect of training
Rate is usually poor with effect.
2), material for training lacks
Most of navigation seaworthiness data is imperfect and is English, the maintenance personal bad for English, English learning data
It is more difficult.Meanwhile the investment of training resource is lacked, cause material for training and examination pool all not perfect.Make training object
It cannot obtain the study and verifying of system.
3), do not focus on induction training
The induction training time is shorter and simple, often participates in real work in the form that master worker trains an apprentice.To industry
In the case that standard and regulation are not all known, the experience of master worker's introduction is possibly relied in work, this will affect later period maintenance
Work the standard executed, and the safety for being unfavorable for maintenance work is carried out.
4), maintenance production task and training conflicts
One maintenance personal holds a concurrent post multiple and different posies often, and each post requires every two years primary refreshment, and one
Maintenance personal will have to receive excessive training, this results in training to occupy a large amount of time of having a rest, generate maintenance personal
Psychology is contradicted, training is difficult to carry out.
5), training program high demarcated standard
Currently, CCAR-145 maintaining unit is according to Advisory Circulars " maintaining unit training program writes guide " (number: AC-
The training program of oneself 145-13) is worked out, training program does not often account for unit practical operation situation, training program and training
There is difference in target, and result of training is bad.
Conventional training method is to show specific operation by specific maintenance examples using PPT or video teaching
Method, to help student to understand maintenance process.This navigation training on maintenance method is commonly used in theory teaching part, can not be with training
Instruction practice is combined closely, and Training Methodology is often and practice generates deviation, this is to cause training efficiency, ropy master
Want reason.
Therefore, current navigation training on maintenance is often carried out in enterprises, is completed in such a way that master worker trains an apprentice, no
The waste of human cost is only caused, while also will affect the production and utilization of enterprise.Promote the training efficiency of navigation maintenance personal
Have become China's navigation great development problem in the urgent need to address with quality.
With the progress of intelligent Manufacturing Technology, the intellectualized technology of manual work is studied to have obtained more and more passes
Note.Many research institutions of the countries and regions such as the U.S., European Union, Singapore, China have widely carried out VR/ in recent years
Research of the AR Technology application to processing, assembly, maintenance etc..
For example, the realization that 104484523 A of Chinese patent literature CN discloses a kind of augmented reality induction maintenance system is set
Standby and method, the program are mainly: by the way that the CAD model of remedial installation is converted to virtual assembly modeling, and according to constraint item
Part, disassembling operations definition space dismount hierarchical tree, in maintenance process, by optical position tracker to maintenance operation people
Member carries out position tracking, maintenance scene identification, clear current maintenance step, according to dismounting hierarchical relationship, to maintenance operation personnel
Corresponding induction information is provided；The CAD model of corresponding maintenance of equipment is imported in advance in use, thus to maintenance of equipment personnel
Corresponding maintenance guiding information is provided, and virtual induction animation is superimposed to real scene.
Above scheme carries out " actual situation combination " using AR technology, the virtual assembly modeling of building is operated with operator true
Real maintenance objects (such as air equipment component) superposition, provides induction information, improves the efficiency of training on maintenance to a certain extent, but
Each student requires a true maintenance objects, and entire training process, still based on unidirectional guidance, overall efficiency is still
It is so to be improved.
