Name of the competing system: iLoc+

Name and email of the responsible person: Stefan Knauth

Date and place: Stuttgart, 25.6.2012

Name

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,

Example values

 

Frequency of generated data in operation

Every 50 msec a dataset is generated.

Name

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

Units

centimeters

Example values

 

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…).

  1. An array of arrays that include: [time, accelerationValue, angularRateValue], every 100ms.
  2. 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
