Python3.x CLI to parser incoming JSON data from actisense-serial and analyzer binaries from CANBOAT and store values into InfluxDB using UDP

Install the CANBOAT repository binaries in order to use actisense-serial and analyzer binaries.

Clone the repository and then install the code:

pip install .

develop using venv:

python -m venv venv

activate the virtual environment and then

pip install -e .

Path to the conf.json (see File in repository for Structure) can be set via argument --config

$ n2kparser --config ./conf.json

The PGNs are configurable via the conf.json file in the repository. Follow the structure mentioned in the file.

A snippet of the PGN is as follows:

"pgnConfigs": {
  "130311": {
    "for": "Environmental Parameters",
    "fieldLabels": [
      "Temperature",
      "Atmospheric Pressure"
    ],
    "topics": [
      "environment/nmea2k/temperature",
      "environment/nmea2k/pressure"
    ]
  },
  "127250": {
    "for": "Vessel Heading",
    "fieldLabels": [
      "Heading"
    ],
    "topics": [
      "control/nmea2k/heading"
    ]
  },
    "127501": {
    "for": "Binary Switch Bank",
    "fromSource": 1,
    "fieldLabels": [
      "Indicator1",
      "Indicator2"
    ],
    "topics": [
      "input/nmea2k/switchbank"
    ]
  }
}

NOTE: A single PGN can measure a different values

• for key is for Human-Readable Description for the PGN. (Optional)
• fieldLabels key is an array of all the relevant keys for which the values should be saved to InfluxDB. Example, for Rudder (same PGN) one can choose to store only Position value or both Direction Order and Position (Required)
• fromSource keys is a filter key to store information from only distinct source (e.g. Engine, Rudder). If there are two Engines/Rudders and the value of Engine/Rudder 1 is to be stored then use fromSource: 1. (Optional)
• topics: A list of topics that are combined with deviceID and published in accordance with the fieldLabels (Required)

<DeviceID>/<Profile>/<Source>/<Measurement>

the payload is in the form of line protocol strings for each topic
