The first step, data parser loads the technical data information of equipment from IETM content data base, comprises the Fault Diagnosis Strategy information of equipment and the configuration information of test platform.The technical data information decomposition of IETM is become varigrained information unit by data parser, and encapsulate so that other component accesses of system in OO mode.
Second step, graphical interfaces manager shows that the interface element of IETM comprises navigation bar, search column, directory tree etc., and shows the homepage of IETM in content displaying district.
The 3rd step, IETM browser sends initialization command to test execution platform, and waits for that initialization procedure is complete.If initialization is unsuccessful, show IETM user's information, information is whether checkout execution platform is normal with the connecting line of equipment object under normal circumstances.
The 4th step, when IETM user has selected after a failure diagnosis task in content displaying district, navigation controller sends diagnosis request to IETM failure diagnosis engine, Fault Diagnosis Strategy is passed to diagnostic engine simultaneously.
The 5th step, the diagnosis algorithm descriptor that IETM browser display failure diagnosis engine returns if specified virtual instrument assembly in this information, loads virtual instrument assembly from test execution platform.
The 6th step, navigation controller receives the feedback message of diagnostic engine, if continue diagnosis, show the descriptor of next diagnosis algorithm, otherwise diagnostic procedure finishes, show diagnostic result information, diagnostic result can be single failure, also can be fault ambiguity group, for representing all possible failure cause.
The 7th step, after failure diagnostic process finishes, IETM browser can select to enter maintenance task unit corresponding to fault.
Fig. 3 is the message structure schematic diagram of diagnosis algorithm element in the inventive method.
The Fault Diagnosis Strategy that navigation controller sends to IETM failure diagnosis engine is made up of one group of diagnosis algorithm element, and diagnosis algorithm comprises step mark, step title, test assignment and one group of test result element.
Whether test assignment element there is fault for certain subsystem or assembly definite or eliminating equipment object, according to the difference of implementation, can be divided into manual test and automatically test two classes.Manual test is described test execution method by elements such as text, form, picture, dialog boxes, and is implemented by IETM user, the test result data that wherein dialog element is selected for receiving user.In addition, manual test can also comprise virtual instrument module information, so that user's Real Time Observation test data information.Automatically test calls to obtain test result data by test program.
The next one that test result element has indicated IETM failure diagnosis engine performs an action, and can be recursively to call another one diagnosis algorithm, also can show that diagnostic procedure finishes, and shows fault message or fault ambiguity group information.Each test result element has a matching condition, and by mating with test result data, failure diagnosis engine can be selected a diagnosis execution route.In the time of multiple test result Satisfying Matching Conditions, the element being arranged in front has higher priority.
Fig. 4 is the process chart of IETM failure diagnosis engine in the inventive method.
The first step, diagnosing controller parses diagnosis algorithm information from Diagnostic Strategy descriptor, and each Fault Diagnosis Strategy comprises one or more diagnosis algorithms.
Second step, diagnosing controller starts to carry out diagnosis algorithm, and each diagnosis algorithm has comprised a test assignment, according to the difference of test assignment type, can be divided into two kinds of situations:
A) under manual execution pattern, diagnosing controller shows the descriptor of test assignment by calling figure interface manager assembly.If comprised virtual instrument assembly in diagnosis algorithm element, diagnosing controller calls the softpanel of figure interface manager this assembly of loaded and displayed from test execution platform according to the identifier of this assembly.IETM user is diagnosed and is described text by reading, and the current indicated value of observing virtual instrument, selects a test execution result in IETM dialog box, and the test execution result of user's input is returned to diagnosing controller by IETM navigation controller.
B) under automatic performance mode, in diagnosis algorithm, include the descriptor of test program, diagnosing controller calls test program adapter and starts test program.Test program adapter, according to the test program access title of describing in IETM, number and the data type of input/output argument, such as, sends test program according to the form of test execution platform external interface (Dynamic Link Library Function, script etc.) to it and carries out request.After test process is finished, execution result is returned to diagnosing controller by test program adapter.
The 3rd step, diagnosing controller is receiving after test execution result, records all data messages of this test execution result by idagnostic logout manager in IETM log database.
The 4th step, diagnosing controller mates the execution result of test cell with the possible test result of describing in diagnosis algorithm: if test execution result shows to carry out another one diagnosis algorithm, turn back to second step, continue to carry out diagnostic procedure; If test finishes, send message to IETM browser, show fault or fault ambiguity group information.
The 5th step, idagnostic logout manager generate diagnosis report, and in IETM log database record.The content of diagnosis report comprises: the diagnosis algorithm title of Diagnostic Time, Diagnostic Strategy title, all execution, the test data information of diagnosis algorithm association, fault or fault ambiguity group information etc.
Fig. 5 is the process chart of test execution platform in the inventive method.
The first step, test platform manager is receiving after initialization command, the software and hardware test resource of initialization platform, and the data link of setting up and equipping object.
Second step, test execution platform enters the state that receives call instruction, according to the difference of call type, can be divided into two kinds of situations:
A) in the time of the virtual instrument component call instruction that receives IETM browser, first test platform manager creates the running example of corresponding virtual instrument assembly, then virtual instrument assembly shows himself softpanel interface, and last virtual instrument assembly obtains by testing hardware equipment and shows the test data of equipping object;
B) in the time receiving the test program call instruction of failure diagnosis engine, first test platform manager loads the test procedure document of specifying according to the mark of test program, then test program drives testing hardware equipment to carry out test assignment according to input parameter, and test program execution result is returned to failure diagnosis engine by last test Platform Manager.
