Abstract

The invention discloses an airborne distributed node debugging method based on an event level. The method comprises the following steps: (1) constructing an event breakpoint; (2) debugging a start-up system; (3) switching the system to the conventional debugging mode to diagnose the trouble source; (4) debugging by monitoring; and (5) repeating the debugging, and stopping the repeated debugging if the fault is not caused by propagation. The invention solves the technical problems of the conventional debugging system, such as complex structure, no fault recurrence, and large cost on the space and the time of the system, and the event-based debugging method pays more attention on the interaction behavior between the nodes so as to reduce the concern on the internal state of a program.

Description

Event-based debugging method for airborne distributed nodes technical field The invention relates to the comprehensive integrated debugging and replaying of airborne distributed nodes of an avionics system, and provides users with a debugging method for specific system events. technical background The traditional debugging method based on the symbolic model has the following obvious deficiencies in the process of debugging distributed software: firstly, it lacks the event-level single-step debugging method, and the traditional debugging method still uses instruction-level single-step operation during single-step execution. Smaller details will waste a lot of time for users and increase the complexity of system debugging; secondly, there is a lack of fault replay means, and for errors that are not easy to reproduce, the system execution process will not be reproducible, and fault diagnosis cannot be performed; finally, traditional debugging based on event models Methods In ...
