| Abstract: | Facing to the bad performance of synchronous communication, the less ability of serial processing and expansibility in existing diagnosis system, a new architecture of distributed remote diagnosis system and event service of CORBA are introduced. We focus on how to use CORBA event service to decoupled and asynchronous alert, distributed calculation as well as enhancing expansibility of system. The implementation details of push model, pull model and event channel in event service are here discussed. The event service of CORBA improved the system performance, reliability of communication and expansibility in the remote diagnosis system. Those method have successfully used in industry. |
