F) diagnostic task unit is for determine or whether certain subsystem of remover apparatus object or assembly there occurs fault.
G) diagnostic result is used for indicating next stage diagnosis algorithm or failure cause and maintenance operation card mark, the corresponding different diagnosis algorithm of different diagnostic results or failure cause and maintenance operation card mark.Then there is no failure cause and maintenance operation card mark when the next stage diagnosis algorithm that diagnostic result is corresponding exists, otherwise when failure cause and maintenance operation card mark exist, then there is no next stage diagnosis algorithm
H) maintenance operation card mark is for recording the maintenance operation card mark of the determined trouble unit of Current Diagnostic step.
Fig. 4 is the course of work schematic diagram of voice interaction module in the inventive method.
The first step, IETM browser completes initialization and exports the diagnostic task sound signal of diagnosis algorithm, and wireless communication module receives this diagnostic task sound signal, and outputs it to dio Output Modules.
Second step, dio Output Modules is play with the form that audio frequency is play and is exported this diagnostic task sound signal.
3rd step, the diagnostic task sound signal that troubleshooting personnel troubleshooting personnel listening to audio output module is play also performs this diagnostic task accordingly, and diagnostic result is said in the form of speech, and voice acquisition module gathers the voice comprising diagnostic result that troubleshooting personnel say.
4th step, sound identification module receives the voice that voice acquisition module gathers, and carries out pre-service and identification to these voice, extracts the diagnostic result voice signal in voice.
5th step, the diagnostic result voice signal after identification is exported to IETM browser in the mode of wireless transmission by wireless communication module, for its driving malfunction diagnostic procedure.After diagnostic result voice signal exports, wireless communication module detects and judges whether IETM browser has new diagnostic task sound signal to export, if any, return the first step and again perform the interactive voice course of work, as exported without diagnostic task audio frequency, then terminate voice reciprocal process.
Below, do not work, further explain and illustrate system and method for the present invention for undercarriage position signalling lamp, the Fault Diagnosis Strategy that undercarriage position signalling lamp does not work is as shown in table 1.
The Fault Diagnosis Strategy that table 1 undercarriage position signalling lamp does not work
Utilize the inventive method as follows to the do not work failure diagnostic process of (assumed fault reason is hydraulic actuator fault) of undercarriage position signalling lamp:
The first step, IETM fault diagnosis engine loads the Fault Diagnosis Strategy stored in IETM content data base, and is exported to interface manager module.
Second step, interface manager module generates user interface, and the interface element of display IETM comprises navigation bar, search column and content displaying district, and in the Fault Diagnosis Strategy that the display of content displaying district loads.
3rd step, phenomenon of the failure Fault Diagnosis Strategy shown in option table 1 in content displaying district that troubleshooting personnel do not work according to undercarriage position signalling lamp, and " startup separator diagnosis " button clicked on navigational tool bar, start the Fault Diagnosis Strategy shown in table 1.
4th step, the Fault Diagnosis Strategy of IETM fault diagnosis engine according to the selection initial table 1 of troubleshooting personnel, extract initial diagnosis step and diagnosis algorithm 1, and the diagnostic task of diagnosis algorithm 1 " jack-up aircraft checks that can undercarriage be packed up and put down " is exported to Data Analysis and modular converter and interface manager module.
5th step, interface manager module receives diagnostic task " jack-up aircraft checks that can undercarriage be packed up and put down ", and it is shown in content displaying district in a flowchart.
6th step, Data Analysis and modular converter receive diagnostic task " jack-up aircraft checks that can undercarriage be packed up and put down ", and resolve it and change, and export to audio detection and Switching Module after making it to be converted to diagnostic task sound signal.Audio detection and Switching Module detect that diagnostic task sound signal outputs it to wireless communication module after inputting.
7th step, the diagnostic task sound signal that wireless communication module receives " jack-up aircraft; check that can undercarriage be packed up and put down ", and output it to dio Output Modules, dio Output Modules is play with the form that audio frequency is play and is exported this diagnostic task sound signal.
8th step, troubleshooting personnel troubleshooting personnel listen to diagnostic task sound signal " jack-up aircraft; check that can undercarriage be packed up and put down " and perform this diagnostic task accordingly, diagnostic result "Yes" or "no" are said in the form of speech, here due to hypothesis airplane hydraulic pressure pressurized strut fault, therefore diagnostic result is "no", voice acquisition module gathers the voice "no" of troubleshooting personnel.
9th step, sound identification module receives voice "no", and pre-service and identification are carried out to these voice, extract the diagnostic result voice signal "no" in voice, this diagnostic result voice signal exports to audio detection and Switching Module by wireless communication module.
Tenth step, audio detection and Switching Module receive this diagnostic result voice signal after diagnostic result voice signal "no" being detected, and output it to command mode matching module.Commands match module exports command mode "no" to IETM fault diagnosis engine after being mated with the command mode such as the "Yes" stored in command mode database, "no", " previous step ", " please come again ", " it fails to match " by the diagnostic result voice signal of "no".
11 step, IETM fault diagnosis engine is according to command mode "no" diagnosis algorithm 1 next stage diagnosis algorithm 3 when diagnostic result is "no" in extraction table 1 from IETM content data base, because diagnosis algorithm 3 exists, therefore the diagnostic task extracting diagnosis algorithm 3 " checks whether Hydraulic Pressure Indicator has hydraulic pressure to indicate ", and output it to Data Analysis and modular converter and interface manager module, repeat from the 5th step.When troubleshooting personnel return to IETM fault diagnosis engine to the diagnostic result "Yes" that diagnostic task sound signal " checks whether Hydraulic Pressure Indicator has hydraulic pressure to indicate ", IETM fault diagnosis engine finds without diagnosis algorithm, and the failure cause " hydraulic actuator fault " when extraction diagnostic result is "Yes" then and maintenance operation card mark " operation sheet 3 " export the content displaying district of human-computer interaction interface to.Troubleshooting personnel can keep in repair according to this failure cause maintenance operation card relevant with maintenance operation card identifier lookup.
