Figure 8. 3D display.
3D
, 3 dimensional display with projections
of each axis acceleration, see Figure 8.
The minimum and maximum resultant
accelerations as well as the current
resultant acceleration are displayed on the
right side of the graph. Minimum and
maximum displays can be cleared by
pressing the "Reset" button.
DATA LOGGER
, display where user can:
-
log data (maximum log time 5 s)
-
view the logged data in [g]
- view the demonstrator speed as a
function time (speed [m/s] is derived by
integrating the acceleration data)
- view the inertial navigation results
(distance [m] as a function of time is
derived by integrating the acceleration
data twice)
To start the data logging press the "Start
measurement" button. The actual data
logging starts when the green "Measuring
data" indicator lights up in the upper right
corner of the window. Data is logged for
predefined time period (“Measure time”).
The results are calculated afterwards. The
green "Measuring data" indicator is
activated also during the result calculation.
Figure 9. Data logger display.
The resultant (acceleration [g], speed [m/s] and distance [m]) is calculated from the respective
3-axis results as follows:
Please notice that inertial navigation contains six degrees of freedom and 3-axis accelerometer can
handle only three degrees of freedom (rotations and tilting can not be detected when inertial
navigation is performed only by 3-axis accelerometer).
