Problems solved by technology

The self-test of the member system is usually inhibited by various conditions. In this case, the user needs to manually perform some operations to ensure the smooth flow of the test process; in addition, what stage is the member system in the self-test process? Or what kind of state, the user cannot know

Embodiment Construction

[0026] The realization process of the present invention is as follows:

[0027] (1) Initialization: At the beginning of software operation, create and initialize the ARINC624 protocol structure, which contains the following key members: request structure, response structure, status enumeration, event list, user request queue, member system message Queue, state machine output queue;

[0028] (2) Start the protocol state machine thread: the initial state of the state machine is NORMAL. In the current state, the state machine monitors the user request event from the WEB man-machine interface, that is, executes the maintenance self-check of a certain member system;

[0029] (3) Maintenance self-inspection operation condition detection: the state machine does not immediately send the request to the member system after receiving the user request, but judges whether the operation condition of the member system maintenance self-inspection is satisfied by the status message of the memb...

Abstract

The invention provides a finite-state machine method for ground tests. On the basis of the ARINC624 protocol, a finite-state machine is created to synchronize the maintenance self-test process of a member system and coordinate the interaction between the member system and a WEB human-machine interface. The method includes initialization, protocol state machine thread starting, maintenance self-test operation condition detection, state machine state transition, interaction coordination and timeout and exception handling. The finite-state machine as an interface which is used by a user to interactively test the member system effectively provides a unified control and handling mechanism.

Description

Technical field: [0001] The invention is used to support the ground interactive test of each member system of the comprehensive maintenance information system, and relates to a finite state machine method for the ground test. Background technique: [0002] Interactive testing is an interactive process between users of the integrated maintenance system and member systems. The self-test of the member system is usually inhibited by various conditions. In this case, the user needs to manually perform some operations to ensure the smooth flow of the test process; in addition, what stage is the member system in the self-test process? Or what state, the user cannot know. [0003] When each member system of the integrated maintenance system supports maintenance self-inspection, if the user performs a self-inspection test on the member system that supports maintenance self-inspection through the operation interface, the integrated maintenance management service (IMMS) will send a ma...
