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.
