摘要
Abstract
The challenge of outdoor installation protection is to realize the outdoor installation of bus protection which can protect multiple bays.This paper proposes a scheme of distributed bus protection and the platform framework of software and hardware based on the multi-loop high-availability seamless redundancy (HSR) protocol network by analyzing the current characteristics of distributed bus protection.To complete the task,first,this paper provides the accurate measurement and compensation for the message delay in the ring network based on FPGA,and puts forward the sampling synchronization based on interruption whicb is independent of external synchronization system.Moreover,this paper provides the loop network topology and simplified configuration for implementing the real-time monitoring of loop network communication and simplified configuration of terminals for the convenience of operation and maintenance.Finally,the proposed scheme is implemented through the actual testing results of the main performance parameters.关键词
