Description
Technical field
The present invention relates to a kind of vehicle control system, in particular to a kind of fault diagnosis system.
Background technique
Linux system is since its open source characteristic and third party abundant are exploited natural resources, by more and more automobiles
The favor of host manufacturer, but currently without unified interface standard, cause the debugging technique of Linux system very various, respectively
There are advantage and disadvantage.Especially in terms of remote debugging and remote diagnosis, current each manufacturer is all in the method for oneself groping oneself.
The problem of currently encountering in linux development process has: test being submitted to carry out integrated survey after software version is integrated
Examination, encounter problems no log record and analysis means, generally requires the machine with debugging mouth and carries out reproduction crawl log log.And
The reproduction probability of some problems is very low, and problem is caused not position in time.
Obviously abnormal grasping means this at present can no longer meet actual project demands, be badly in need of a kind of more efficient more quasi-
True abnormal localization method solves the problems, such as that current practical item development encounters.
Summary of the invention
The object of the present invention is to provide a kind of linux onboard system abnormity diagnostic systems, utilize the core dump of linux
Technology carries out the storage of abnormality, realizes that long-range connection and abnormal log upload automatically using wifi and 3G technology, maximum limit
State when occurring extremely is reported to developer and analyzed by degree at the first time.
The object of the present invention is achieved like this: a kind of linux onboard system abnormity diagnostic system and its diagnostic method, institute

WEB server is responsible for establishing the long-range connection between vehicle device and PC；
The end PC provides the client for receiving abnormal log for developer；
The diagnostic method the following steps are included:
2) step 1) gos to step when some program of the system that detects is operating abnormally；
Step 2 detects whether that setting starts automatic upload function, gos to step 3) if starting, otherwise jumps to step
It is rapid 5)；
Whether step 3) detection system connect normal with WEB server, gos to step 4) if connection is normal, otherwise jumps
Go to step 8)
Step 4) uploads abnormal log, and user's abnormal log is prompted to upload successfully；
Step 5) system prompt user currently has program operation exception, and user is required to choose whether to upload, and jumps to
Step 6)；
Step 6) jump procedure 3 if user selects to upload), if user's selection does not upload jump procedure 7)；
Step 7) carries out local abnormal storage management, and abnormal kernel dump is carried out corresponding local management, is guaranteed subsequent
User correctly can carry out USB export or WEB server manually imports；
Step 8) system prompt user chooses whether to connect WEB server manually, gos to step 13) if selection is,
Otherwise it gos to step 9)；
Step 9) system prompt user chooses whether to export using USB flash disk, gos to step 10) if selection is, otherwise jumps
Go to step 7)；
Step 10) starts USB flash disk and detects program, and whether detection USB flash disk is inserted into, if detecting that USB flash disk is already inserted into, jumps to step
It is rapid 11), if detection USB flash disk be not inserted into, jump to step 12)；
Step 11) starts USB flash disk deriving step, by USB flash disk derived from abnormal log, and user's USB flash disk is prompted to export successfully；
Step 12) prompts user to be inserted into USB flash disk, if user confirms insertion USB flash disk, gos to step 10), continues to test U
Whether disk is inserted into success；
Step 13) enters connection WEB server function manually, guarantees the functions such as WIFI connection and 3G network exploitation, operation
It finishes and jumps directly to step 3), whether detection connection is normal.
