Abstract: Based on the model of the remote fault diagnosis for aircraft,the mechanism of collaboration is proved to resolve the limitation of traditional fault diagnosis.The model on remote collaborative diagnosis and concurrent controlling based on the role in aircraft is brought forward through the analysis of the relationship between the collaborative colonies and the roles in the course of collaboration and the analysis of positions of all collaborative colonies in the environment of collaboration.Collaborative colonies（Virtual Groups of the tasks,VG） can be built dynamically and automatically in it,more alternation and collaboration can be achieved in VG.According to analysis of roles and tasks dynamically,the locking mechanism is adopted to harmonize the relationship of roles so as to avoid the conflict between roles,the roles can be collaborated and the data also can be changed each other easy.The result of the fault diagnosis is more exact and integrated.

Key words: fault diagnosis, collaborative, concurrent controlling, locking mechanism
