摘　　要：为提高智能录波器采集单元数据支撑的可靠性,提出一种智能录波器采集单元去中心化技术方案,采集单元按被记录元件分布式安装,采集单元之间双网冗余连接以提高数据传输可靠性,延时可测网络对时实现各采集单元同步采样,联网同步触发实现扰动数据全景捕获,每个采集单元除记录本体接入的采样数据,同时向其他采集单元发送自身采样数据,并接收和记录来自其他采集单元的数据,访问任意采集单元可获取全部记录数据,为扰动分析和故障处理提供可靠的数据支撑。实际应用表明,多套采集单元只要有任一存储介质完好,就能保证数据记录的完整性,该技术方案能有效解决采集单元数据支撑可靠性的问题。In order to improve the reliability of data support of the intelligent fault recorder acquisition unit,a decentralized technical scheme for the acquisition unit of intelligent fault recorder is proposed.The acquisition units are installed in a distributed panel according to the recorded components.The redundant network connection between the acquisition units improves the reliability of data transmission.The time synchronization of the time delay measurable network enables synchronous sampling of each acquisition unit.The cross trigger enables panoramic capture of disturbed data.In addition to recording the sampling data accessed by itself,each acquisition unit sends its own sampling data to other acquisition units,at same time receives and records data from other acquisition units.All recorded data can be obtained by accessing any acquisition unit to provide reliable data support for disturbance analysis and fault processing.The practical application shows that as long as any storage medium of multiple acquisition units is intact,the integrity of data records can be guaranteed,and this technical solution can effectively solve the problem of data support reliability of the acquisition unit.
