Configure Docker#

To configure Docker:

Run Docker as Non-Root: Follow the steps in Manage Docker as a non-root user.

Configure Proxy (if required):

Set up proxy settings for Docker client and containers as described in Docker Proxy Configuration.

Example ~/.docker/config.json:

{
  "proxies": {
    "default": {
      "httpProxy": "http://<proxy_server>:<proxy_port>",
      "httpsProxy": "http://<proxy_server>:<proxy_port>",
      "noProxy": "127.0.0.1,localhost"
    }
  }
}

Configure the Docker daemon proxy as per Systemd Unit File.

Enable Log Rotation:

Add the following configuration to /etc/docker/daemon.json:

{
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "10m",
    "max-file": "5"
  }
}

Reload and restart Docker:

sudo systemctl daemon-reload
sudo systemctl restart docker

Clone source code#

git clone https://github.com/open-edge-platform/edge-ai-suites.git
cd edge-ai-suites/manufacturing-ai-suite/industrial-edge-insights-time-series

Data flow explanation#

The data flow remains same as that explained in the High-Level Architecture. Let’s specifically talk about the wind turbine anomaly detection use case here by ingesting the data using the OPC-UA simulator and publishing the anomaly alerts to MQTT broker.

Data Sources#

Using the edge-ai-suites/manufacturing-ai-suite/industrial-edge-insights-time-series/apps/wind-turbine-anomaly-detection/ingestor-data/wind-turbine-anomaly-detection.csv which is a normalized version of open source data wind turbine dataset (edge-ai-suites/manufacturing-ai-suite/industrial-edge-insights-time-series/apps/wind-turbine-anomaly-detection/training/T1.csv) from https://www.kaggle.com/datasets/berkerisen/wind-turbine-scada-dataset. This data is being ingested into Telegraf using the OPC-UA protocol using the OPC-UA data simulator.

Data Ingestion#

Telegraf through its input plugins (OPC-UA OR MQTT) gathers the data and sends this input data to both InfluxDB and Time Series Analytics Microservice.

Data Storage#

InfluxDB stores the incoming data coming from Telegraf.

Data Processing#

Time Series Analytics Microservice uses the User Defined Function(UDF) deployment package(TICK Scripts, UDFs, Models) which is already built-in to the container image. The UDF deployment package is available at edge-ai-suites/manufacturing-ai-suite/industrial-edge-insights-time-series/apps/wind-turbine-anomaly-detection/time-series-analytics-config. Directory details is as below:

`config.json`:#

The task section defines the settings for the Kapacitor task and User-Defined Functions (UDFs).

Key	Description	Example Value
`model_registry`	Configuration for the Model Registry microservice.	See below for details.
`udfs`	Configuration for the User-Defined Functions (UDFs).	See below for details.

Model Registry Configuration:

Key	Description	Example Value
`enable`	Boolean flag to enable fetching UDFs and models from the Model Registry microservice.	`true` or `false`
`version`	Specifies the version of the task or model to use.	`"1.0"`

UDFs Configuration:

The udfs section specifies the details of the UDFs used in the task.

Key	Description	Example Value
`name`	The name of the UDF script.	`"windturbine_anomaly_detector"`
`models`	The name of the model file used by the UDF.	`"windturbine_anomaly_detector.pkl"`
`device`	Specifies the hardware `CPU` or `GPU` for executing the UDF model inference.Default is `cpu`	`cpu`

Note: The maximum allowed size for config.json is 5 KB.

Alerts Configuration:

The alerts section defines the settings for alerting mechanisms, such as MQTT protocol. For OPC-UA configuration, please refer Publishing OPC-UA alerts. Please note to enable only one of the MQTT or OPC-UA alerts.

MQTT Configuration:

The mqtt section specifies the MQTT broker details for sending alerts.

Key	Description	Example Value
`mqtt_broker_host`	The hostname or IP address of the MQTT broker.	`"ia-mqtt-broker"`
`mqtt_broker_port`	The port number of the MQTT broker.	`1883`
`name`	The name of the MQTT broker configuration.	`"my_mqtt_broker"`

`config/`:#

kapacitor.conf would be updated as per the config.json at runtime for usage.

`udfs/`:#

Contains the python script to process the incoming data. Uses Random Forest Regressor and Linear Regression machine learning algos accelerated with Intel® Extension for Scikit-learn* to run on CPU to detect the anomalous power generation data points relative to wind speed.

`tick_scripts/`:#

The TICKScript windturbine_anomaly_detector.tick determines processing of the input data coming in. Mainly, has the details on execution of the UDF file, storage of processed data and publishing of alerts. By default, it is configured to publish the alerts to MQTT.

`models/`:#

The windturbine_anomaly_detector.pkl is a model built using the RandomForestRegressor Algo. More details on how it is built is accessible at edge-ai-suites/manufacturing-ai-suite/industrial-edge-insights-time-series/apps/wind-turbine-anomaly-detection/training/windturbine/README.md

Deploy with Docker Compose#

Update the following fields in .env:
- INFLUXDB_USERNAME
- INFLUXDB_PASSWORD
- VISUALIZER_GRAFANA_USER
- VISUALIZER_GRAFANA_PASSWORD
- MR_PSQL_PASSWORD
- MR_MINIO_ACCESS_KEY
- MR_MINIO_SECRET_KEY
Deploy the sample app, use only one of the following options:

NOTE:

The below make up_opcua_ingestion or make up_mqtt_ingestion fails if the above required fields are not populated as per the rules called out in .env file.

The sample app is deployed by pulling the pre-built container images of the sample app from the docker hub OR from the internal container registry (login to the docker registry from cli and configure DOCKER_REGISTRY env variable in .env file at edge-ai-suites/manufacturing-ai-suite/industrial-edge-insights-time-series)

The CONTINUOUS_SIMULATOR_INGESTION variable in the .env file (for Docker Compose) and in helm/values.yaml (for Helm deployments) is set to true by default, enabling continuous looping of simulator data. To ingest the simulator data only once (without looping), set this variable to false.

If CONTINUOUS_SIMULATOR_INGESTION is set to false, you may see the [inputs.opcua] status not OK for node message in the telegraf logs for OPC-UA ingestion after a single data ingestion loop. This message can be ignored.

make up_opcua_ingestion is supported only for Wind Turbine Anomaly Detection

Deploying Wind Turbine Anomaly Detection#

Using OPC-UA ingestion:

make up_opcua_ingestion app="wind-turbine-anomaly-detection"

Using MQTT ingestion:

make up_mqtt_ingestion app="wind-turbine-anomaly-detection"

Multi-Stream Ingestion#

Multi-stream ingestion allows you to process multiple data streams in parallel. This feature is available only for the Wind Turbine Anomaly Detection sample app.

To enable multi-stream ingestion, specify the desired number of parallel streams using the num_of_streams parameter:

# OPC-UA Multi-Stream Ingestion
make up_opcua_ingestion app="wind-turbine-anomaly-detection" num_of_streams=<NUMBER_OF_STREAMS>

# MQTT Multi-Stream Ingestion
make up_mqtt_ingestion app="wind-turbine-anomaly-detection" num_of_streams=<NUMBER_OF_STREAMS>

<NUMBER_OF_STREAMS>: Replace with the number of parallel streams you want to run (e.g., 3 for three streams).

Deploying Weld Anomaly Detection#

make up_mqtt_ingestion app="weld-anomaly-detection"

Use the following command to verify that all containers are active and error-free.

Note: The command make status may show errors in containers like ia-grafana when user have not logged in for the first login OR due to session timeout. Just login again in Grafana and functionality wise if things are working, then ignore user token not found errors along with other minor errors which may show up in Grafana logs.

make status

Running UDF inference on GPU#

To trigger the UDF inference on GPU in Time Series Analytics Microservice, run the following command:

 curl -k -X 'POST' \
 'https://<HOST_IP>:3000/ts-api/config' \
 -H 'accept: application/json' \
 -H 'Content-Type: application/json' \
 -d '<Add contents of edge-ai-suites/manufacturing-ai-suite/industrial-edge-insights-time-series/apps/wind-turbine-anomaly-detection/time-series-analytics-config/config.json with device
     value updated to gpu from cpu>'

Note: GPU Inferencing is supported only for Wind Turbine Anomaly Detection sample app
