如何使用 Seeq 和 TDengine 进行时序数据分析

方案介绍

Seeq 是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。

Seeq 安装方法

Seeq 官网下载相关软件,例如 Seeq Server 和 Seeq Data Lab 等。

Seeq Server 安装和启动

tar xvzf seeq-server-xxx.tar.gz
cd seeq-server-installer
sudo ./install

sudo seeq service enable
sudo seeq start

Seeq Data Lab Server 安装和启动

Seeq Data Lab 需要安装在和 Seeq Server 不同的服务器上,并通过配置和 Seeq Server 互联。详细安装配置指令参见Seeq 官方文档

tar xvf seeq-data-lab-<version>-64bit-linux.tar.gz
sudo seeq-data-lab-installer/install -f /opt/seeq/seeq-data-lab -g /var/opt/seeq -u seeq
sudo seeq config set Network/DataLab/Hostname localhost
sudo seeq config set Network/DataLab/Port 34231 # the port of the Data Lab server (usually 34231)
sudo seeq config set Network/Hostname <value> # the host IP or URL of the main Seeq Server

# If the main Seeq server is configured to listen over HTTPS
sudo seeq config set Network/Webserver/SecurePort 443 # the secure port of the main Seeq Server (usually 443)

# If the main Seeq server is NOT configured to listen over HTTPS
sudo seeq config set Network/Webserver/Port <value>

#On the main Seeq server, open a Seeq Command Prompt and set the hostname of the Data Lab server:
sudo seeq config set Network/DataLab/Hostname <value> # the host IP (not URL) of the Data Lab server
sudo seeq config set Network/DataLab/Port 34231 # the port of the Data Lab server (usually 34231

TDengine 本地实例安装方法

请参考官网文档

TDengine Cloud 访问方法

如果使用 Seeq 连接 TDengine Cloud,请在 https://cloud.taosdata.com 申请帐号并登录查看如何访问 TDengine Cloud。

如何配置 Seeq 访问 TDengine

  1. 查看 data 存储位置
sudo seeq config get Folders/Data
  1. 从 maven.org 下载 TDengine Java connector 包,目前最新版本为3.2.5,并拷贝至 data 存储位置的 plugins\lib 中。

  2. 重新启动 seeq server

sudo seeq restart
  1. 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

本章节演示如何使用 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);

Seeq demo schema

构造数据方法

python mockdata.py
taos -s "insert into power.goods select _wstart, _wstart + 10d, avg(goods) from power.meters interval(10d);"

使用 Seeq Workbench

登录 Seeq 服务页面并新建 Seeq Workbench,通过选择数据源搜索结果和根据需要选择不同的工具,可以进行数据展现或预测,详细使用方法参见官方知识库

Seeq Workbench

用 Seeq Data Lab Server 进行进一步的数据分析

登录 Seeq 服务页面并新建 Seeq Data Lab,可以进一步使用 Python 编程或其他机器学习工具进行更复杂的数据挖掘功能。

from seeq import spy
spy.options.compatibility = 189
import pandas as pd
import matplotlib
import matplotlib.pyplot as plt
import mlforecast
import lightgbm as lgb
from mlforecast.target_transforms import Differences
from sklearn.linear_model import LinearRegression

ds = spy.search({'ID': "8C91A9C7-B6C2-4E18-AAAF-XXXXXXXXX"})
print(ds)

sig = ds.loc[ds['Name'].isin(['Num'])]
print(sig)

data = spy.pull(sig, start='2015-01-01', end='2022-12-31', grid=None)
print("data.info()")
data.info()
print(data)
#data.plot()

print("data[Num].info()")
data['Num'].info()
da = data['Num'].index.tolist()
#print(da)

li = data['Num'].tolist()
#print(li)

data2 = pd.DataFrame()
data2['ds'] = da
print('1st data2 ds info()')
data2['ds'].info()

#data2['ds'] = pd.to_datetime(data2['ds']).to_timestamp()
data2['ds'] = pd.to_datetime(data2['ds']).astype('int64')
data2['y'] = li
print('2nd data2 ds info()')
data2['ds'].info()
print(data2)

data2.insert(0, column = "unique_id", value="unique_id")

print("Forecasting ...")

forecast = mlforecast.MLForecast(
models = lgb.LGBMRegressor(),
freq = 1,
lags=[365],
target_transforms=[Differences([365])],
)

forecast.fit(data2)
predicts = forecast.predict(365)

pd.concat([data2, predicts]).set_index("ds").plot(title = "current data with forecast")
plt.show()

运行程序输出结果:

Seeq forecast result

配置 Seeq 数据源连接 TDengine Cloud

配置 Seeq 数据源连接 TDengine Cloud 和连接 TDengine 本地安装实例没有本质的不同,只要登录 TDengine Cloud 后选择“编程 - Java”并拷贝带 token 字符串的 JDBC 填写为 Seeq Data Source 的 DatabaseJdbcUrl 值。 注意使用 TDengine Cloud 时 SQL 命令中需要指定数据库名称。

用 TDengine Cloud 作为数据源的配置内容示例:

{
"QueryDefinitions": [
{
"Name": "CloudVoltage",
"Type": "SIGNAL",
"Sql": "SELECT ts, voltage FROM test.meters",
"Enabled": true,
"TestMode": false,
"TestQueriesDuringSync": true,
"InProgressCapsulesEnabled": false,
"Variables": null,
"Properties": [
{
"Name": "Name",
"Value": "Voltage",
"Sql": null,
"Uom": "string"
},
{
"Name": "Interpolation Method",
"Value": "linear",
"Sql": null,
"Uom": "string"
},
{
"Name": "Maximum Interpolation",
"Value": "2day",
"Sql": null,
"Uom": "string"
}
],
"CapsuleProperties": null
}
