Description
Technical field
The invention belongs to aircraft navigation field, and in particular to a kind of control display unit exerciser.
Background technology
Control display unit CDU can provide navigation system working mode selection, aerial mission plan editor, air route point selection
And position correction and demarcation, communication system working mode selection and parameter setting, task application parameter setting, control display unit
It is the important component of man-machine interaction.As can be seen here, it must be verified before installation, it is ensured that its is functional, otherwise
The work of automated driving system can be influenceed.Current our factory is not also for the testing equipment of this component.By the function on panel
Key, numerical key, letter key and peripheral key receive the operation of pilot；Operated by simulation and discrete signal interface HOCAS
Signal；Key information, control instruction and display data, HOCAS buttons and vernier information are interacted with GPU by AFDX networks.
The content of the invention
The technical problem to be solved in the present invention：
Property indices to control display unit are tested.Flight is ensured, the rate of breakdown of aircraft is reduced.
Technical scheme：
A kind of control display unit exerciser, including main processing block 1, pattern process module 2, power module 4, display group
Part 3, analog quantity 5, discrete magnitude 6, the signal of AFDX procotols 7 carry out data processing generation RS422 letters from the input of main processing block 1
Numbers 9, the RS422 signals 9 are input into self-defined bus pattern process module 2 by special circuit, other signal clearances cross from
Define bus 8 and be input to pattern process module 2, pattern process module 2 pairs receives signal and processes, generate vision signal 10,
And vision signal 10 and RS422 signals 9 are sent to display module 3.
Beneficial effects of the present invention：
Control display unit exerciser of the present invention can complete man-machine interface and the test of Multi-Function Keyboard, can monitor discrete magnitude
Analog signalses, and system debug reset signal and control signal etc.；By back production components A FDX Ethernet data, enter
Row closed loop detects whether test synthesis display control program bus communication meets the requirements.
Brief description of the drawings
Fig. 1 is the schematic diagram of control display unit exerciser 12；
Fig. 2 is connection figure.
Specific embodiment
With reference to Fig. 1, the exerciser detects HOCAS operation signals by the reception to analog quantity 5, discrete magnitude 6；Pass through
AFDX procotols 7 interact the information such as key information, control instruction and display data with main processing block 1, by image procossing
After the treatment of module 2, most measured information is presented in display module 3 at last.
It is the connection diagram of control display unit exerciser 12 and control display unit 11 with reference to Fig. 2, will control in figure
Display unit 11 is connected with avionics system joint-trial platform 13, represents what control display unit 11 was gathered from avionics system joint-trial platform 13
Each data process and obtain analog quantity 5, discrete magnitude 6, the signal of AFDX procotols 7.
Specific detecting step：
Control display unit 11 is connected with avionics system joint-trial platform 13, then control display unit 11 is single with control display
First exerciser 12 is connected, and connects 220V power supplys to control display unit exerciser 12, avionics system joint-trial platform 13 respectively.
A) man-machine interface and Multi-Function Keyboard inspection：Verification personnel can be by pressing pressing on the panel of control display unit 11
Key, or condition selecting and information input operation are carried out to control display unit 11, then check control display unit exerciser 12
Whether the information of middle display is consistent with actually entering；
B) cockpit information translation function：The reception processing of control display unit exerciser 12 is gathered by control display unit 11
Control stick and the output of the equipment such as avionics control panel discrete magnitude, analog quantity, display turns in control display unit exerciser 12
Change the corresponding information of completion；
C) the manual automatic regulation function inspection of display brightness：Brightness regulating button in regulation control display unit 11, control
There is respective change in the display module brightness of display unit exerciser 12 processed,；Light sensitive component in control display unit 11 is entered
Row is blocked, and the display module brightness of control display unit exerciser 12 occurs respective change；
D) self-test function：The self-inspection button in control display unit exerciser 12 is clicked on, can be to control display unit 11
Self-test is carried out, corresponding test data is generated after the completion of self-test, test result can be shown.
