摘要
设计了带自动方向控制的半双工RS485通信模块,构建了一套总线形与星形结构混合的多层分布式电力设备在线监测通信体系,提出了适应于该体系的序列号绑定的广播通信协议。增强了系统在同步数据采样、选择性回收和数据融合方面的性能。长时间测试表明:该网络通信稳定可靠,故障隔离能力强,数据选择回收简单且具有较高的性价比,非常适合于监测点多、实时性要求较强的大规模监测系统。
An automatic direction control half-multiplex RS485 communication module is designed. A bus-type and star-type mixed multi-layer distributed power apparatus on-line monitoring communication architecture is built. A broadcast communication method bundled with serial number is put forward. The system abilities of synchronous data acquisition, selective retrieving and data fusion are enhance. It is proved after long time test that new communication system works stably, has high fault separation ability, retrieves data easily, has high performance cost ratio and is very conformable used in multi-point, real-time large scale monitoring system.
