МТ-700 fleet tracking system 61
Remote accelerometer configuration
Accelerometer can be configured using SMS-commands.
Accelerometer calibration check
is executed using the CheckCalibration.
Terminal response:
ID(CheckCalibration): horizon: resultH (causeH); linear: resultL
(causeL)
Where resultH, resultL – are the results of the horizon setting and linear
calibration:
ок – calibration is OK
warning –
calibration is on the edge of the allowable range
fault - calibration is over the allowable range
causeH – horizon calibration cause:
not calibrated
– calibration was not achieved
out of range – horizon vector is over the allowable range
angle A – angle between the horizion vector and current vector
line L, side S – false additive to the linear and lateral acceleration added
by the gravity (if linear calibration was conducted)
causeL – linear calibration cause:
not calibrated – calibration was not conducted
angle A – angle between the linear calibration vector and linear statistic vector
Response:
ID(CheckCalibration):horizon: fault (not calibrated);
linear: fault (not calibrated)
Accelerometer state indication
is conduction through the SMS=command
getacceleration
Response from the terminal:
Id(getacceleration):accel(acc), angle(ang),current(Xc,Yc,Zc),
horizon(Xh,Yh,Zh),line(Xl,Yl,Zl)
ID – is the tracker ID
acc – current linear acceleration (no value if the linear calibration was not
conducted)
ang – angle to the horizon (0, if horizon is not set)
Xc,Yc,Zc – current “raw” data for the 3 axes
Xh,Yh,Zh
– horizon calibration vector (3 axes); if it’s not calibrated – not calibrated
Xl,Yl,Zl – calibration vector(3 axes). If not calibrated = not calibrated (no horizon
or not calibrated )
Terminal’s response:
ID(getacceleration): angle(4), current (-
59,52,1039), horizon(14,-22,1044), line(not calibrated)
Value of the parameter “accelerometer port threshold”
can be requested using the following
SMS-command: getaccelgage
Response:
id(getaccelgage): OК
