Abstract
Against the diagnosis difficulty of some complex system with distributed characteristic, a distributed diagnosis model whose center is object-relational constraint database is put forward-Firstly, the foundation method of object-relational constraint database is researched. Then, the architecture of constraint relational object query language is described. Lastly, distributed diagnosis structure and algorithm are presented. The application of a satellite system proves that the diagnosis is very fast, the coupling results between sub-system can be diagnosed which are suitable in fault diagnosis for complex system such as satellite.
