GL100 @Track Air Interface Protocol
4.7. Movement Detect
The “Movement Detect” function is used to disable fixed timing report when the terminal stays in
the same place without moving for a long time in order to save the communication cost and power
consumption. The function is set by the
AT+GTSFR
command.
An example is given as following:
AT+GTSFR=gl100,1,1,0,0,
1
,
20
,
500
,
3
,0,20090101000000
<
movement detect mode
> = 1;
<
movement speed
> = 20;
<
movement distance
> = 500;
<
movement number
> = 3.
The parameter <
movement detect mode
> is used to enable/disable the movement detect function.
The terminal will check the movement status according to <
movement speed
> and <
movement
distance
>:
If the distance between current position and previous is longer than <
movement distance
> (in
m), the terminal will be considered as moving.
If the speed is faster than <
movement speed
> (in km/h), the terminal will be considered as
moving.
The method to report is described as following:
If <
send interval
> = <
fix interval
>, every report message includes one position record. The
terminal will report <movement number> times to the backend server when it is not moving.
If <
send interval
> != <
fix interval
>, every report message includes several position logs. The
terminal will report all position logs to the backend server however the speed of non-moving
points will be set to -1.
