8.2.1.3 Energy-Saving Mode
If the battery charge in the TMSO.CU drops so low that reliable system operation can no longer
be guaranteed, the system switches to an aggressive energy-saving mode. The aim is to
reduce energy consumption to a minimum and thus give the solar cell the opportunity to
recharge the battery to a safe level.
During this state the system will behave as follows:
No more measurements are performed, even if a measurement plan has been set
The sleep cycle length is set to the maximum (12 hours)
The status update rate is set to the maximum (24 hours)
As soon as the battery has reached a safe state of charge again, the system returns to its
original configuration and also continues any measurement plans that may have been started.
8.2.1.4 Data Storage in the Cloud
During the preparation of the system activation, the system test is carried out (
Meanwhile, the TMSO.CU also connects to the cloud. There the folder TMSO is created (if not
already existing), under it the project folder and in it 2 files.
After the system is activated, more files will be uploaded over time.
\Dropbox\TMSO\OC-0004_1574935540\OC-0004.cfg
\Dropbox\TMSO\OC-0004_1574935540\OC-0004.cmd
\Dropbox\TMSO\OC-0004_1574935540\OC-0004_000.log
\Dropbox\TMSO\OC-0004_1574935540\OC-0004_1574936000.tmso
The name of the project folder consists of the last digits of the serial number of the TMSO.CU,
in the following example the device no. OC00-0000-0004 and the UNIX time stamp of the start
of the system test. The names of the files also start with the serial number part.
The name of the log file is supplemented by a 3-character index. As soon as the file size
exceeds 100kB, a new file with an index increased by 1 is created.
For each measurement cycle the TMSO.CU creates a data file with all recorded measurement
data. After the serial number part in its name is the UNIX time stamp at which this measuring
cycle was started.
