1 DEVICE PURPOSE AND OPERATION PRINCIPAL
DEVICE PURPOSE
Vega NB-14 modem is designed for monitor of insulation state of the warm network
pipelines and for control of integrity of pipelines signal wires, further accumulating and
transmitting of this information in NB-IoT network.
Modem allows to detect the following defects:
wet insulation;
the breakage of the signal wires;
closing of the signal wire to the pipe (detected like ‘wet insulation’ defect).
Modem does not detect a reason and a place of defect appearing
In addition, Vega NB-14 can be used as a security device – two additional inputs operate
in security mode, there is also Hall sensor.
The modem can be used on pipelines with polyurethane foam heat insulation and/or
collect data from 1-Wire interface connected temperature sensors etc.
The modem is may powered by one or two batteries with capacity 6400 mAh.
OPERATION ALGORITHM
The readings collecting from the meter with a configurable period 5, 15, 30 minutes, 1,
6, 12 or 24 hours. The readings stored in the device memory and transmitting during the next
communication session with the NB-IoT network.
The adjustable data transfer period can be equal to 5, 15, 30 minutes, 1, 6, 12 and 24
hours. Data transferring in random point in time during set period. 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-14 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.
