Abstract

The invention belongs to UAV Flight Control technologies, are related to a kind of method for being remotely controlled removing unmanned plane and flying guard system failure.The present invention is sent telecommand and removed by wireless test and control link flies guard system failure, fault reset switch is removed by pressing in ground control station pilot, fly guard system in the case where meeting clear failure reset interlock condition, winged guard system Airborne Software is reinitialized and removes nonvolatile memory internal fault information in winged pipe computer.The present invention connects PMA to aircraft without surface personnel, shortens flight preparation time and runway occupancy time, improves the rapid touch ability of aircraft, especially alleviates the burden of surface personnel.

Description

It is a kind of to be remotely controlled the method that unmanned plane flies guard system failure of removing
Technical field
The invention belongs to UAV Flight Control technologies, are related to a kind of be remotely controlled and remove the side that unmanned plane flies guard system failure Method.
Background technology
Unmanned plane needs to be purged failure reset to flying guard system (Aircraft Management System) in flight preparation on runway, Unfaulty conditions is in fly guard system when unmanned plane takes off.Previous aircraft removes failure reset to flying guard system, needs By the way that portable maintenance equipment (PMA) is connected to aircraft special maintenance plug on ground service runway.PMA after the power is turned on, needs to open It safeguards that software is manually entered and removes failure reset order.
Invention content
The purpose of the present invention is：A kind of method for being remotely controlled removing unmanned plane and flying guard system failure is provided.
The technical scheme is that：It is a kind of to be remotely controlled the method that unmanned plane flies guard system failure of removing, pass through wireless test and control Link, which sends telecommand and removes, flies guard system failure, i.e., removes failure reset by pressing in ground control station pilot and open It closes, flies guard system in the case where meeting clear failure reset interlock condition, winged guard system Airborne Software is reinitialized and removes winged pipe Nonvolatile memory (NVM) internal fault information in computer, including：
A) remote control switch decodes
Winged guard system, which receives decision instruction after the clear failure remote control switch code that wireless test and control link is sent continues 480ms, to be had Effect.
B) it is remotely controlled clear failure reset interlock protection
The following interlock condition of failure reset button setting is removed to prevent earth station personnel from accidentally pressing：
1) 5s is not responding to be remotely controlled clear failure reset instruction before system initialization
2) wheel load vote value is ground；
3) unmanned plane is not driven into or out of；
4) task of loading is aerial mission and mission phase word is await orders stage or flight ending segment；
5) task of loading is the task that slides and mission phase word is the stage of awaiting orders or slides ending segment.
The beneficial effects of the invention are as follows：The present invention provides a kind of are remotely controlled to remove unmanned plane and flies the method for guard system failure, PMA (portable maintenance equipment) is connected to aircraft without surface personnel, shortens the flight preparation time and when runway occupies Between, the rapid touch ability of aircraft is improved, especially alleviates the burden of surface personnel (especially in high temperature, sleet etc. Bad weather).
Description of the drawings
Fig. 1 is that the flow chart that unmanned plane flies the method for guard system failure is removed in present invention remote control.
Specific embodiment
The specific embodiment of the present invention is described further below in conjunction with the accompanying drawings.
The design difficulty of the present invention is：
A) how to prevent from being remotely controlled clear fault reset switch false triggering；
B) how to prevent from being remotely controlled clear fault reset switch and be continuously pressed；
C) pressing clear fault reset switch time span has uncertainty.
For more than difficult point, key point of the invention is to fly the interlock condition of the clear failure reset of guard system response remote control Judge.
Referring to Fig. 1, the present invention is a kind of to be remotely controlled the method that unmanned plane flies guard system failure of removing, and is sent out by wireless test and control link Telecommand is sent to remove and flies guard system failure, i.e., fault reset switch is removed by pressing in ground control station pilot, flies pipe Winged guard system Airborne Software is reinitialized and removed in winged pipe computer in the case where meeting clear failure reset interlock condition by system Nonvolatile memory (NVM) internal fault information, includes the following steps：
A) remote control switch decodes
Winged guard system, which receives decision instruction after the clear failure remote control switch code that wireless test and control link is sent continues 480ms, to be had Effect.
B) it is remotely controlled clear failure reset interlock protection
The following interlock condition of failure reset button setting is removed to prevent earth station personnel from accidentally pressing：
1) 5s is not responding to be remotely controlled clear failure reset instruction before system initialization
2) wheel load vote value is ground；
3) unmanned plane is not driven into or out of；
4) task of loading is aerial mission and mission phase word is 0 (awaiting orders the stage) or 8 (flight ending segments)；
5) task of loading is 0 (awaiting orders the stage) or 3 (sliding ending segment) to slide task and mission phase word.
