precision
— text data describing a selected number precision (e.g.: 0.00 mean
two decimal digits),
part data format description
Specific log data. There can be the following types of data:
–
raster
— holds information about samples interval,
•
Sample ID
in hexadecimal notation
(called:
R
id
),
•
raster value (in seconds) (called:
R
v
),
–
timestamp
— samples synchronization markers,
•
sample ID in hexadecimal notation (called:
T
id
),
•
sample time (called:
T
t
),
–
samples
— channels measurements data. Channel order is the same as row order
in
log.db_log_files
:
•
sample ID in hexadecimal notation (called:
S
id
),
•
floating point text representation of sample value for the first logged channel
•
…
•
floating point text representation of sample value for the N-th logged channel.
How to calculate the precise sample time
To calculate the time of the sample number
S
id
use the below procedure:
– Find
R
v
and maximum
R
id
where
R
id
≤ S
id
,
– Find
T
t
and maximum
T
id
for
T
id
≤ S
id
,
– Calculate the sample time (
S
t
) using the given equation:
S
t
= T
t
+ R
v
· (S
id
– T
id
)
Detailed description of files
File
main_log.bin_logs
contains:
–
ID
– unique decimal number identifying log,
–
GROUP_NO
– number of a logged group (corresponding to a device's group),
starting from 0,
–
DIR
– name of directory with log files., e.g. “g0_2010_08_04_13_50_39”. The name
of a directory is created according to the scheme below:
“gX_YYYY_MM_DD_hh_mm_ss”, where:
•
X
– group number,
