作为一款制造业和工业互联网（IIOT）高级分析软件，Seeq 支持在工艺制造组织中使用机器学习创新的新功能。这些功能使组织能够将自己或第三方机器学习算法部署到前线流程工程师和主题专家使用的高级分析应用程序，从而使单个数据科学家的努力扩展到许多前线员工。通过 TDengine Java connector，Seeq 可以轻松支持查询 TDengine 提供的时序数据，并提供数据展现、分析、预测等功能。本文将对此进行介绍。
如何配置 Seeq 访问 TDengine
1. 查看 data 存储位置
sudo seeq config get Folders/Data2. 从 maven.org 下载 TDengine Java connector 包，目前最新版本为 3.2.7 （Maven Central: com.taosdata.jdbc:taos-jdbcdriver）。并拷贝至 data 存储位置的 plugins\lib 中。
3. 重新启动 seeq server
sudo seeq restart4. 输入 License
使用浏览器访问 ip:34216 并按照说明输入 license。
使用 Seeq 分析 TDengine 时序数据
下文将为大家演示如何使用 Seeq 软件配合 TDengine 进行时序数据分析。
场景介绍
示例场景为一个电力系统，用户每天从电站仪表收集用电量数据，并将其存储在 TDengine 集群中。现在用户想要预测电力消耗将会如何发展，并购买更多设备来支持它。用户电力消耗随着每月订单变化而不同，另外考虑到季节变化，电力消耗量会有所不同。这个城市位于北半球，所以在夏天会使用更多的电力。我们模拟数据来反映这些假定。
数据 Schema
CREATE STABLE meters (ts TIMESTAMP, num INT, temperature FLOAT, goods INT) TAGS (device NCHAR(20));
create table goods (ts1 timestamp, ts2 timestamp, goods float);
构造数据方法
python mockdata.pytaos -s "insert into power.goods select _wstart, _wstart + 10d, avg(goods) from power.meters interval(10d);"源代码托管在 https://github.com/sangshuduo/td-forecasting。
使用 Seeq 进行数据分析
配置数据源（Data Source）
使用 Seeq 管理员角色的帐号登录，并新建数据源。
