ai_on_edge_with_fiware

This is a project to implement an AI on Edge application with FIWARE.

Environment Setup

Architecture

Smart Data Model

This project utilizes the WeatherObserved smart data model. This standardized schema enables structured representation of weather observations, including key meteorological parameters (temperature, humidity, wind speed, atmospheric pressure) and geospatial-temporal data.

Prerequisites

• Docker
• Docker Compose
• Alternatively, Podman and Podman Compose

Context Broker environment setup

Orion Context Broker is used to manages context information.

MongoDB is used by the Orion Context Broker to hold context data information such as data entities, subscriptions and registrations.

• To test if the Context Broker service is running correctly, send a POST request to the Context Broker to create a new entity of the WeatherObserved data model:

curl -iX POST 'localhost:1026/ngsi-ld/v1/entities' \
  --header 'Content-Type: application/json' \
  --data-raw '{
    "id": "urn:ngsi-ld:WeatherObserved:Berlin-2024-07-15T06:26:00",
    "type": "WeatherObserved",
    "dateObserved": {
      "type": "Property",
      "value": "2024-07-15T06:26:00Z"
    },
    "location": {
      "type": "GeoProperty",
      "value": {
        "type": "Point",
        "coordinates": [13.41053, 52.52437]
      }
    },
    "address": {
      "type": "Property",
      "value": {
        "addressCountry": "DE",
        "addressLocality": "Berlin"
      }
    },
    "temperature": {
      "type": "Property",
      "value": 18
    },
    "relativeHumidity": {
      "type": "Property",
      "value": 0.80
    },
    "precipitation": {
      "type": "Property",
      "value": 0.1
    },
    "windSpeed": {
      "type": "Property",
      "value": 3.5
    },
    "windDirection": {
      "type": "Property",
      "value": 150
    },
    "atmosphericPressure": {
      "type": "Property",
      "value": 1015
    },
    "weatherType": {
      "type": "Property",
      "value": "Partly cloudy"
    },
    "source": {
      "type": "Property",
      "value": "https://www.weatherapi.com"
    }
  }'

• Query the Context Broker:

curl -iX GET 'localhost:1026/ngsi-ld/v1/entities/urn:ngsi-ld:WeatherObserved:Berlin-2024-07-15T06:26:00'

If the entity is correctly created, you should have as a result an entity of type WeatherObserved created in the Context Broker.
