The Mode-switch technology of machine system, feasible system switches between normal mode and backup mode；The realization pair under normal mode
The pitching of air refuelling boom, rolling, flexible closed-loop control, to the opened loop control of air refuelling boom folding and unfolding, in backup mode
The lower opened loop control realized to air refuelling boom folding and unfolding.
The present invention technical solution be：A kind of air refuelling boom control computer system, it is characterised in that：Including
Back up switch, joystick, attitude angle transducer, air refuelling control computer, velocity sensor, actuator sensor, after
Hold executing agency；
The air refuelling control computer is two, and every air refuelling control computer configuration order and monitoring are logical
Road, each passage includes digital processing element and analog processing unit；Digital processing element has the backup logic of functional independence
Process circuit；
The backup switch, joystick, attitude angle transducer, velocity sensor, actuator sensor and rear end are held
Row mechanism is crosslinked with air refuelling control computer；
The joystick, attitude angle transducer, velocity sensor, actuator sensor and rear end executing agency, sky
Middle refueling control computer constitutes closed loop Flying by wire system, realizes to the pitching of air refuelling boom, rolling, flexible closed loop control
System；
The backup switch, air refuelling control computer, rear end executing agency constitute open cycle system, realize and add to aerial
The folding and unfolding opened loop control of oily boom.
A kind of Mode-switch method of air refuelling boom control computer system, it is characterised in that：Methods described includes
Following steps：
1) each passage collection backup on off state of air refuelling control computer, and this is logical to the forwarding of other 3 passages
Road signal, the finally most synchronous votings of 4 tunnels backup switch acquisition state progress including this channel signal, voting result is determined
The operation mode of this fixed passage；When voting result is normal mode, system enters normal work mode, when voting result is standby
During part mode, system enters back-up job mode；
2) system enters after normal mode, and when detecting permanent fault, system will automatically switch to backup mode；
3) system enters normal mode, if detection backup on off state is starts backup modal state, system will enter
Back-up job mode.
When system is in normal mode, air refuelling control computer receive the flexible, pitching from handle, rolling,
Folding and unfolding is instructed；Comprehensive flexible, pitching, rolling position feedback, output control is instructed after being calculated through control law；
Analog processing unit receives the control instruction of digital processing element output, integrates actuator sensor feedback information,
The flexible of air refuelling boom, pitching, the closed-loop control of rolling are realized, the opened loop control of air refuelling boom folding and unfolding is realized.
When system is in back-up job mode, air refuelling control computer receives backup switch order, and will instruction
Analog processing unit is passed to, the folding and unfolding opened loop control of air refuelling boom is realized.
Beneficial effects of the present invention：
With Mode-switch function, it can be achieved to switch between normal mode and backup mode；It is right under normal mode to realize
The flexible of air refuelling boom, rolling, the closed-loop control of pitching, can guarantee that and are still realized to air refuelling under backup mode again
The folding and unfolding control of boom.A kind of majority voting mechanism for backup switch collection is proposed, backup switch collection shape is can guarantee that
The correctness of state.
Brief description of the drawings
