12.3.1.4 Length of a Measuring Cycle
This parameter determines how long the devices of the PTMSO measure and record data
continuously and autonomously.
A measurement cycle is started by the TMSO.CU if an active measurement plan requires this.
Thereupon all TMSO.IM switch off their radio modules and start measuring.
When the measuring cycle time is over, all devices stop the measurement and reactivate their
radio modules. The TMSO.CU then queries the recorded data and transfers it to the cloud. If
the measurement plan requires the measurement to be continued at this time, the TMSO.CU
starts the next measurement cycle.
Reducing the measurement cycle length increases the resolution, since more cycles can be
run in the same period of time and thus more inclination events can be recorded
(corresponding to
12.3.1.1Max. Number of Events per Measuring Cycle
).
However there is of course a higher energy consumption as the communication intervals of
the system are reduced and the amount of data to be transmitted is increased.
The default setting is 60 minutes. This was based on the typical temporal resolution of publicly
available wind measurements (from weather stations).
12.3.1.5 Length of a Sleep Cycle
The same applies to the sleep cycle length as to the measurement cycle. This setting
determines the length of the communication interval while the system is in sleep mode.
After each cycle all devices wake up briefly, exchange status information and the TMSO.CU
starts a new cycle.
The default setting is 30 minutes.
12.3.1.6 Relationships Between the Time Cycle Settings
Compliance with the cycle times has the highest priority. This also defines the communication
times between the TMSO.IM and the TMSO.CU, as well as the times when it is possible to
connect to the cloud.
That means:
Status information (later lines in the log file) is only recorded during such
communication times.
In measurement mode a connection to the cloud is established after each completed
measurement cycle.
In sleep mode a connection to the cloud is only established when a sleep cycle has
expired and a log update is to be performed. You set this interval with the
Status log
update period
parameter in the Configuration tab (
INP
) in the management window.
an update setting of 12 hours, i.e. 12 hours after the last update, the system waits
for the current cycle to expire and then actually carries out the update.
NOTE!
Each time it connects to the cloud, the TMSO.CU downloads the current command file (OC-
XXXX.cmd) and checks for an updated measurement plan.
If a log update period of 12h is set and the system is in sleep mode, then a new measurement
plan set by the user will in extreme cases only be adopted by the system 12h later!
12.3.2 Construction Site Monitoring (CSM)
Available via future firmware update.
