The t-rake temperature data acquisition system is a 16-channel Analog-to-Digital converter (A/D) with 16-bit resolution per channel and a high-throughput capability, allowing for high-speed high-resolution data capture. This document discusses how the acquired data is stored on file.
The configuration file will be installed at
[TBD]
It will be named trakeconfig.json. Its format will follow this pattern:
{
"dataPath": "/trake/data",
}The data file name will be based on the time stamp at the moment data acquisition is started, and will be of the form
yyyy-mm-dd_hh.mm.ss.csv
Multiple files will be stored in the configured data path, and will not collide, since they will all have unique file names.
The data stored in the aqcuisition files will be ASCII numeric, stored as comma-separated variable (CSV) files. They will contain a time tick, which is the offset in milliseconds since the file was started, plus a column for each channel. All channel data will be raw, with no temperature conversions applied.
Example,
tick,Channel0,Channel1,Channel2,Channel3,Channel4,Channel5,Channel6,Channel7,Channel8,Channel9,Channel10,Channel11,Channel12,Channel13,Channel14,Channel15
