摘　　要：针对即有SCADA系统可扩展性差、承载大容量数据处理效率低等问题,提出了基于JGroups技术建立统一、高效的系统通讯机制的解决方案,并以此为核心设计、实现了分布式的、松散耦合的SCADA系统。测试结果表明,该系统能较好地满足远动业务及性能需求,证明本文提出的将组播通讯应用于SCADA系统的可行性及有效性。For the problems that SCADA system is difficult to extend, and the efficiency is slow for large data processing, this paper proposes the solution to establish a unified, efficient communication mechanism of system based on JGroups,and designes and implements distributed, loosely coupled SCADA system by using this mechanism as the core. The test results indicats that the system can meet the performance requirements and business needs of SCADA system better, it certificats that group communication technology applied to SCADA system is feasible and effective
