6 General operation modes
In this chapter, the behavior of the operation modes is described. For information on how to configure the CISS or how to
receive data from it, please refer to Chapter 7.
6.1 General behaviour
The individual sensors in the CISS can be activated / deactivated for measurements.
Additionally, different sampling rates can be given for the inertial sensors and the environmental sensors.
The sensors within the CISS are grouped into two clusters:
The first cluster comprises the inertial measurands (acceleration, angular velocity, magnetic field). Besides the sampling
rate, which applies to all inertial sensors, each sensor can be configured individually.
The second cluster is comprised of all environmental sensors (temperature, humidity, pressure, light, noise).
Equally, the sampling rate applies to all sensors, while each sensor can be activated or deactivated individually.
The reporting of the results is structured accordingly.
6.2 Resetting the CISS
The integrated microcontroller of a CISS performs a reset when it is detached from a USB host or power supply or it gets
unmounted (e.g. with the “unmount” command in a Linux-system).
The CISS settings will be reset, the logged data will be preserved.
Note: Exception: Disabling the 2 kHz acceleration streaming mode will cause a reset.
6.3 Logging data to the local memory
When the CISS is configured to log measurements to its local memory, a file will be created in the user data memory,
that is accessible as a mass storage device over USB.
If the local memory is full, the logging will be stopped.
It is possible to concurrently log to memory and stream data via BLE.
The time, until the memory is full, depends on the settings of the CISS.
Example 1:
Sensors: All sensors activated
Sampling rate inertial sensors: 0,01 sec
Sampling rate environmental sensors: 60 sec
Allows logging for approx. 6 min
Example 2:
Sensors: Acceleration sensor and environmental sensors activated
Sampling rate inertial sensors: 0,01 sec
Sampling rate environmental sensors: 60 sec
Allows logging for approx. 10 min
23
The format of the log file is an ASCII-file, with comma separated values (filename: log<time>.csv). The filename corresponds
to the time counter in the microcontroller at the beginning of the measurement. In the file, the first three lines contain header
information on the measurement. This includes a comma-separated list of the selected measuring dimensions, e.g.:
Time(ms),ax,ay,az,gx,gy,gz,mx,my,mz,Temp,Humidity,Pressure,Light,Noise
After this line, the measurements are given according to the defined columns. If present, inertial and environmental lines are
interleaved according to the sampling intervals.
Each line always contains all columns (i.e. the number of commas per line is constant). Each sensor has its own line and
column.
The CISS microcontroller has an internal time counter which is used for the timestamp when logging to the local memory.
Per default, this counter starts at zero after a power cycle. To get an absolute time, the counter may be set to a UNIX
timestamp through the corresponding USB or BLE commands (see Chapter 7).
6.4 Streaming via USB
When streaming over USB, the measurements from the sensors in the CISS are offered through a virtual serial port (virtual
COM port 115kBaud 8N1) continuously. The configuration commands as well as the data format of the streamed sensor
measurements are described in Chapter 7.
With this mode, it is possible to use the maximum sampling frequency of 2 kHz for the 3-axis accelerometer with a special
configuration. In this case, only the accelerometer is enabled.
Note: Access to the noise measurement data is only available via BLE.
6.5 Streaming via BLE
The CISS per default acts as a Bluetooth Low Energy (BLE) advertiser. This means that another BLE device may detect the
CISS when scanning for devices and is able to initiate a connection.
Using BLE, it is possible to configure a CISS and continuously receive measurement data from it.
For details on the available Bluetooth characteristics, please refer to Chapter 7. It is possible to concurrently stream data
via BLE and log to memory.
INFO: It is not possible to use the special mode of the accelerometer (sampling rate = 2 kHz)
when streaming via BLE.
6.6 Event detection mode
In the event detection mode, the user is able to define thresholds for one or multiple sensor signals of the CISS.
Each time the respective measurement signal crosses the threshold level, an event is generated and signaled via USB / BLE.
The event message contains the direction of the threshold crossing, i.e. if the signal was below the threshold and goes above
or vice-versa (termed overshoot/undershoot), see Chapter 7.
INFO: Each sensor has the possibility to set only one threshold. The possibility to set a threshold range
is not implemented, yet.
24
6.7 Time aggregation mode
The time aggregation mode is a special USB streaming mode, which reduces the frame rate compared to the sampling rate of
the sensors. Measurements are aggregated in time frames and then the minimum, maximum, mean and standard deviation
of these time frames are reported.
Currently, the CISS contains a fixed configuration for the time aggregation mode:
Acceleration & angular velocity, sampling rate 100Hz, time frame 2s
Temperature, sampling rate 1Hz, time frame 10s
See chapter 7 for the format of the signaled USB messages.
INFO: When entering the time aggregation mode, the BLE functionality of the CISS is completely
switched-off (i.e. the CISS will no longer advertise).
