# 动态数据解决方案 |
||||
|
|
||||
|
目前本地化和平台的高频接入情况: |
||||
|
|
||||
|
## 案列1 海文铺前大桥 |
||||
|
|
||||
|
**ET降采样** 设备:光纤光栅 期望20Hz 实际 平台接入展示1分钟 |
||||
|
|
||||
|

||||
|
|
||||
|
## 案例2 动态数据接入安心云平台 |
||||
|
|
||||
|
特征值存储, 动态数据按数组存储 |
||||
|
|
||||

||||
|
|
||||
|
## 案列3 铁四院独立部署 |
||||
|
|
||||
|
光纤光栅300个设备10Hz连续接入,2.0本地化时序库版本 |
||||
|
|
||||

|
## 说明 |
||||
|
|
||||
|
+ ### 降低采样频率 |
||||
|
|
||||
|
+ 案例:高频本地化系统 |
||||
|
+ 优:与普通数据一致,不需要作特殊处理 |
||||
|
+ 劣:粒度丢失 |
||||
|
|
||||
|
+ ### 压缩展示 |
||||
|
|
||||
|
+ 案例:目前振动接入平台方式;动应变接入 |
||||
|
|
||||
|
+ 优:满足接入和绘图性能 |
||||
|
|
||||
|
+ 劣:数据展示不够直接;延迟高(批次采集完后上报) |
||||
|
|
||||
|

||||
|
|
||||
|
+ ### 独立服务器 + 时序库 |
||||
|
|
||||
|
+ 案例:铁四院独立部署 |
||||
|
|
||||
|
+ 优:性能满足 |
||||
|
|
||||
|
+ 劣:2.0架构。需独立部署时序数据库 |
||||
|
|
||||
|
本地化展示方式,支持按聚集查询和实时粒度查询 |
||||
|
|
||||
|
|
||||
|
|
||||
|
+ ### 独立提取(附部分ET计算功能) + MQTT + HDFS文件存储 + 后端绘图 |
||||
|
|
||||
|
+ 案例:无项目使用。定制化高频接入预研。 |
||||
|
|
||||
|
+ 优:性能满足。后端python绘图,显示性能高 |
||||
|
|
||||
|
+ 劣:较复杂:数据处理在下位机(边缘)。暂无项目应用 |
