picolog: For PicoTech PicoLog data

+
+

yadg.extractors.picolog.tc08 module

+

Module for parsing PicoTech PicoLog files, such as those generated by the TC-08 +thermocouple reader.

+
+

Usage

+

Available since yadg-5.1.

+
+
+pydantic model dgbowl_schemas.yadg.dataschema_5_1.filetype.PicoLog_tc08
+
+
Config:
+
    +

  • extra: str = forbid

    • +
+
+
Validators:
+

+
+
+
+field filetype: Literal['picolog.tc08'] [Required]
+
+ +
+ +
+
+

Schema

+
xarray.Dataset:
+  coords:
+    uts:            !!float           # Unix timestamp, optional
+  data_vars:
+    {{ name }}      (uts)             # Temperature of the named thermocouple
+
+
+
+
+

Metadata

+

Metadata about the TC-08 device is read from the overall metadata file. The following +parameters are currently parsed:

+
    +

  • Model: model number of the network analyseer

    • +

  • Serial: serial number of the device

    • +

  • Software Version: software version with which the file was created

    • +
+
+
+

Uncertainties

+

Uncertainties in temperatures are set to 2.2°C, which is the usual value for a Type-K +thermocouple.

+
+
+

Notes on file structure

+

The .picolog files are actually .tar archives, which include the following +files:

+
    +

  • a metadata.json file, containing information about the device and the +thermocouples plugged in,

    • +

  • a data-map.json.gz file, containing information about chunks of data corresponding +to each thermocouple,

    • +

  • a set of zipped binary files with data averaged at different time resolutions

    • +
+

Currently, the data is extracted from the 1.0.gz file only.
