Abstract:
The traditional devices used in industry for data acquisition to monitor operational
efficiencies are mostly based on SCADA systems which comprises of a network of
devices/sensors linked together via RS485 wires, communicating through MODBUS
protocol. The data from these sensors is processed by a gateway and then sent to the
server by means of Ethernet cables.
The issues with the system discussed above is that it is very costly and due to the
limitations of the wire as well as just one data acquisition protocol, not all the sensors can
be incorporated.
We have developed an IOT based generic sensory node which can acquire data from
sensors mounted on the job floor machines which provide output in voltage, current or
Modbus protocol. Moreover, it is based on wireless networking of nodes using the Radio
frequency communication technique. The nodes form a RF network within themselves
and act as slaves, parse the data to each other until it arrives at the master node for further
processing and uploading to the website. We can use this data further for analysis
regarding the maintenance requirements of those machines. We have also developed a
shaker table for analysis of the vibrations being generated due to shaft eccentricity and
monitoring the power consumption by it.
