The Research of Synchronization in Condition Monitoring and Diagnosis System

摘要

The article introduces a condition monitoring analysis and diagnosis system, analyzes the synchronization requirement of data acquisition,and provides a hybrid system-FSRHS combining the LonTalk protocol with a multiplexed bus for fast synchronized response, FSRHS takes advantage of predominant network capability of LonWorks and steers by protocol spending of LonWorks. By multiplexing LonWorks and setting response content with LonTalk message in advance, acquisition nodes can get speedy and accurate response, thus the synchronization problem is solved. Application layer acknowledgements instead of Data Link layer acknowledgements make it possible to detect and respond to partial network failures, and this increases the robustness and reliability of the network.
