Abstract(s)
Constant search for efficiency and productivity
has led to innovation on the factory shop floor, representing an
evolution of the current production systems combined with
new technologies of industrial automation and information
technology. This work presents an experimental demo of a
smartbox for Industry 4.0 scenarios, allowing sensing,
monitoring and data acquisition. We have tested two different
approaches, depending on the communication protocol used
for real time applications: OPC UA or MQTT. Raspberry Pi’s
platform act as an OPC UA server or MQTT broker,
respectively. From the measurements, data stored in a cloud
server can be accessed remotely with improved security and
visualized from a computer dashboard. One of the conclusions
that can be drawn is that both protocols allow data from the
smartbox to be stored and easily monitored from a smartphone
application or a computer web interface. MQTT is a good
option in communications requiring very low bandwidth.
However, there is a lack of suitable libraries to program alarm
features for OPC UA Servers.
