SECURED WIRELESS COMMUNICATION FOR INDUSTRIAL AUTOMATION AND CONTROL
Abstract--Wireless based industrial automation is a prime
concern in our day-to-day life. The approach to Zigbee Based
Wireless Network for Industrial Applications standardized
nowadays. In this paper, we have tried to increase these
standards by combining new design techniques to wireless
industrial automation. The personal computer based wireless
network for industrial application using Zigbee can be adopted
at micro and macro Industries, it has various types of
Processors and Microcontrollers. Here Microcontrollers,
Temperature Sensors, Zero crossing detector, Voltage
regulators are used. The system is fully controlled by the
Personal Computer through Visual Basics GUI (Graphical
User Interface).The GUI is developed based on application by
the user. All the processor and controllers are interconnected
to personal computer through Zigbee. The Personal Computer
will continuously monitor all the Data from remote processing
unit and compare with value preloaded process structure. If
any error is found the personal computer takes necessary
action. Here star topology four node Zigbee network is tried.
The first Zigbee is connected to the personal computer it acts
as full function devices and is used to send and receive data
from other nodes. The second, third and fourth Zigbee are
reduced function devices and they are used to control the
speed of DC motor, temperature control and lamp illumination
control respectively. All the Zigbee’s are interconnected with
processing unit through RS232 protocol.
