| 摘要: |
| 介绍了基于CIA（Community Intelligence Agent）模型的水电机组融合监测框架：CIA模型包含消息处理层、行为控制层及核心功能层3个层次，各CIA与外界（如其他CIA）通过Request消息或Report消息联系；融合监测框架由维护域CIA系统和控制域CIA系统构成，维护域CIA系统各CIA之间通过实时现场总线（如CAN总线）或工业以太网实现交互、协作、关联动作及数据共享。将整个机组的状态数据划分为原始采样数据、瞬变状态数据、详细状态数据及概要状态数据4个层次，并针对不同层次的状态数据，进行选择性智能存储，以提高机组运动状态分析和故障诊断的针对性及有效性，节约存储空间。通过时间融合、运行工况融合、异常事件融合和冲突解决策略，实现融合监测系统中各CIA之间实时交互、协作及关联动作和机组状态数据的融合，有效地保证来自机组不同子系统的运动状态的关联性。 |

| Abstract: |
| The framework of integrated monitoring of hydroelectric generators based on CIA（Community Intelligence Agent） model is introduced，which is made up of the CIA system in control domain and the CIA system in maintenance domain. The CIA model contains the message processing layer，behavior control layer and core functional layer，and each CIA contacts with external module （such as other CIAs） through Request message or Report message. The interaction，collaboration，associated action and data sharing among all CIAs in maintenance domain are realized via the real-time field bus （such as CAN bus） or Ethernet. The state data of whole hydroelectric generators are divided into the sampled data，transient data，detailed data and summary data，for which the selectively intelligent storage is applied to improve the pertinence and validity of state analysis and fault diagnosis with less storage space. The real-time interaction，collaboration，associated action among CIAs in monitoring system and the state data fusion of hydroelectric generators are realized through the time fusion，operating condition fusion，abnormal event fusion and conflict resolution strategy，which effectively guarantees the relevance of operating states from different subsystems of hydroelectric generators. |
