1 DEVICE PURPOSE AND OPERATION PRINCIPAL
DEVICE PURPOSE
Vega NB-11 pulse counter is designed for counting of pulses incoming to 4 independent
inputs, further accumulating and transmitting of this information in NB-IoT network.
In addition, Vega NB-11 can be used as a security device – two additional inputs operate
in security mode, there is also Hall sensor.
The pulse counter can be used for any utilities’ meters and industrial equipment with
pulse output of herkon type or open-drain type.
Equipment with NAMUR pulse output is not supported
The counter is powered by a 6400 mAh built-in battery.
OPERATION ALGORITHM
The readings collecting from the meter with a configurable schedule. The readings
stored in the device memory and transmitting during the next communication session with the
NB-IoT network.
Data are transferred with a configurable schedule too. Data can be transferred in random
point in time during set period or in the set time. At the next communication session, the device
starts sending accumulated packets with readings, from the earliest to the latest.
The device operates with confirmation all the time and send the next packet only after
receiving a confirmation of the delivery of the previous one. If such confirmation was not
received, NB-11 completes the communication session until the next one according to the
schedule. Herewith, the device continues to collect data according to the data collection
period and store it in memory. Non-transmitted packets remain in the device memory until the
next communication session.
The internal clock is set automatically when device connected to the "Vega NB-IoT
Configurator" via USB.
