Sensor Raw Data
|
|
Description of the information measured
|
Ultrasound Time of Flight Data
The data Stream received from the about 26 sensors
Data is in text format, each line is a dataset and contains:
relative time stamp, sensor id, slot number, and the TOF times of the four slots preceeding the current time slot. A time slot is about 50 ms long.
|
|
Units
|
relative timestamp is a integer number, counting in units of 100 usec the time which has passed since the receiver has been switched on
each TOF value is a 4 hex digit number giving the ultrasound time of flight in units of 1 usec,

|
Frequency of generated data in operation
|
Every 50 msec a dataset is generated.

Calculated position data raw
|
|
Description of the information measured
|
Every 50 msec a raw position is calculated and written to the log
Dataset contains: time when line is written, slot# and relative reception time of last dataset, calculated position xyz, involved sensor id's

|
Frequency of generated data in operation
|
Generated every 50ms.

After, for instance, 30 minutes operation you generate the following data sets (this is the information you will finally provide to evAAL together with this questionnaire in a format that must be agreed before the competition). Please provide information about the files with data (examples are, text file, or video) and format (.csv, .txt, .xls…).
- An array of arrays that include: [time, accelerationValue, angularRateValue], every 100ms.
- Others…
Files:
- iloc_sensor_data.txt // append-only file which logs all raw data
- iloc_raw_pos.txt // append-only file which logs all calculated raw positions
- iLoc_xmitted_pos.txt // append-only: this is a log containing the information transmitted to the socket adapter
- iloc_mean_tof_calib.txt // this contains sensor readings generated during calibration phase
- iloc_fixed_nodes_pos // Read Only: this is a pre-engineered file containing positions where reference nodes and marker nodes are/shall be placed
- iloc_nodes_pos // this is the file where the system-estimated node positions are stored after the auto-calibration phase
