流式数据集与推送数据集

功能概述

通过使用 Wyn,可以轻松实现流式数据的处理,流式数据轻松对接,并且将流式数据实时展示到仪表板中。实时直观的改变数据图表,让整个仪表板更加动态。

随着车间数据的实时性要求越来越高,IOT 数据采集功能要求日益增长,那么随之而来的各类解决方案也就顺应时势的崭露头角。

本次带来的流式数据,就是为了解决这一环节的数据痛点。通过对接设备源,工厂传感器,社交媒体流,服务器敏感数据收集,空气质量检测点数据发送等等一系列高频次数据源。第一时间对接数据,完成可视化展示。






实现方法

在 Wyn 中,我们有两种类型的实时数据推送数据集:

  • 推送数据集

  • 流式数据集

首先我们先来了解一下这些数据集之间的区别。

推送数据集

使用推送数据集,数据将直接推送到 Wyn 服务中。Wyn 服务在接收到数据后,会自动创建一个数据表用来存储数据集。

因为有一个服务会不断的将数据传入进行存储,所以我们每次通过仪表板,数据集所查询到的数据都是最新的。根据此数据集创建对应的报表/仪表板。通过此数据集所创建的仪表板/报表与其仪表板/报表的使用方式是一样的。完全拥有的仪表板的所有功能,对于报警,数据刷新等等功能完全适用。

使用推送数据集后,每次刷新后,都会将数据实时展示到仪表板中。如果仪表板中设置自动刷新,则每次数据集中有数据变化后,就会实时反馈在仪表板中。达到实时展示。

接收实时数据,并且根据设定时间清空原先内容,可以处理吞吐量大,实时性高的数据。

流式数据集

使用流式数据集,数据也会被直接推送到 Wyn 服务中。Wyn 服务在接收到数据后,会自动创建一个数据缓存。

与推送数据集有个本质的区别就是流式处理数据集不会创建数据表,只会临时存储到缓存中,根据设定存储时间会过期。过期后则数据自动清空。临时缓存仅仅用于展示一些历史存在过的数据。只用来表示数据历史,如一个小时内的空气质量检测,一个小时内的设备运行状态等历史数据。实时的显示出一个小时内数据的折线图等效果图。

在实际应用中,流失数据集对象最适合处理最小化数据,对于时间维度来说具有非常强的表现能力。可以直观的显示出所推送的数据。

在数据处理逻辑,数据推送中使用方法一致。只是不会定时清理数据。

数据可视化

通过以上两种数据接入方式,支持数据主动接收,被动接收,对在未来物联网时代的数据接入,提供了更加方便的对接方式。

数据推送过来了,接下来需要做的就是将数据可视化了。
