Abstract
According to the strict synchronization requirements of parameter measurement for ro-tary machine and the concentrated distribution characteristics of telemetry nodes,a RNBS technology was provided.By the wired communication among reference nodes,the broadcast news arrived at each node simultaneously,and then the time message and the moment of message arrival time were used for time synchronization.RNBS has advantages of high accuracy,high efficiency,easy realization in whole net and easy application in engineering.At last,RNBS was tested on the self-developed plat-form.The results show that the synchronization error is less than 1 ms inside 30 minutes,and differ-ent precisions can be achieved by setting the synchronous cycle,which meets the requirements of time synchronization in multi-parameter telemetry for rotary machine.关键词
