Description
Technical field
The invention belongs to Unmanned Aerial Vehicle Data process field, more particularly to a kind of unmanned aerial vehicle maintenance system of MVC frameworks
And method.
Technical background
With aviation and the development of electronic technology, new unmanned plane during flying performance is more and more stronger, and task device is also increasingly
It is superior.In order to ensure that unmanned plane safely and reliably completes aerial mission, the integration test before daily dimension inspection is carried out to it and is let fly away
It is more and more important.The major function of unmanned aerial vehicle maintenance system is detection and daily dimension before being taken off to UAS
Shield detection, particularly carries out on-line checking and analog manipulation to the critical component on machine and visual plant before take-off, to confirm
Whole UAS working condition, the information that decision-making provides abundance is let fly away to be final.
Current unmanned aerial vehicle maintenance system does not have a unified standard, is typically the test proposed according to user
The testing requirement that is constantly found in demand and Aircraft Management System design process is designed.Therefore the demand of system may
Change at any time, this is accomplished by ground-based maintenance systems energy fast reaction, adapt to Aircraft Management System Airborne Software or other things
The change of equipment is managed, and unmanned aerial vehicle maintenance system does not use a suitable frame model mostly at present, it is impossible to effective place
The drawbacks of reason system is difficult to safeguard and expanded, when changes in demand, it is difficult to quickly react.
Aircraft Management System realizes that the data between redundance subsystem are handed over using cross channel data link road (CCDL) method
Change, reduce the complexity and cost of Aircraft Management System so that be supplied to the communication resource of ground-based maintenance systems to be reduced to one
It is individual, under single communication resources supplIes, if synchronization sends maintenance instruction and periodic status query statement and will cause communication
Resource access conflict, destroys the instruction execution result of the instruction sent and reception, and the realization of most of maintenance systems at present is not
Allow to send maintenance instruction and periodic status query statement simultaneously；Because periodic status query statement can occupy logical for a long time
Believe resource, cause maintenance instruction can not send for a long time, reduce maintenance efficiency.
So in the prior art, unmanned aerial vehicle maintenance system, which exists, safeguards and expands difficult, the low shortcoming of maintenance efficiency.
The content of the invention
It is an object of the present invention to provide one kind is easy to safeguard and expanded, a kind of high MVC frameworks of maintenance efficiency nobody

User input instruction implementing result in step 7, interaction echo module display caching area；
Subsystem state query statement implementing result in step 8, subsystem monitors data disaply moudle display caching area.
In steps of 5, periodic status query statement is divided into multiple small status inquiry instructions by communication interface, using having
Limit state machine approach, which sends small status command to Aircraft Management Computer, can ensure that small status command all sends successfully and held
OK.
The beneficial outcomes of the present invention are：System uses MVC frame models, system module is layered, subsystem state circle
Face is separate, effectively overcomes conventional service logic and data manipulation mixes the disadvantage that caused system is difficult to safeguard and expanded
End.Using Multithread Synchronization Program, synchronization can only have a communication interface modules to access the single communication resource, can be achieved
Sent while user input instruction and periodic status query statement, efficiently solve the collision problem concurrently accessed, it is ensured that
Instruction send or implementing result integrality；Communication interface modules will periodically using instruction segmentation and finite state machine method
Status inquiry instruction is divided into multiple small status inquiry instructions to send, and shortens query statement to the holding time of the communication resource, carries
The real-time of high user input instruction.
