SECURED WIRELESS COMMUNICATION FOR INDUSTRIAL AUTOMATION
AND CONTROL
[attachment=53051]
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.
INTRODUCTION
In recent years, wireless sensor networks have become
widely spread in many areas including industrial data
transfer and process control applications. Some of these
applications outgrow the traditional communication model
applied to wireless sensor networks according to which data
is flowing towards a single receiver (sink). In the case of
industrial data acquisition systems more than one receiver is
a viable model.
WIRELESS COMMUNICATION
Wireless communication is the transfer of information
over a distance without the use of electrical conductors or
wires. The distances involved may be short (a few meters as
in television remote control) or long (thousands or millions
of kilometers for radio communications).It encompasses
various types of fixed, mobile, and portable two-way radios,
cellular telephones, personal digital assistants (PDAs), and
wireless networking. Here we use the wireless network for
industrial data communication.
Zigbee Protocol
Zigbee is a wireless network protocol specifically
designed for low data rate sensors and control networks. The
applications that can benefit from the Zigbee protocol are
building automation networks, home security systems,
industrial control networks, patient monitoring, remote
metering etc .
Zigbee uses the IEEE 802.15.4 physical and MAC layers
to provide standard-based, reliable wireless data transfer[7].
Zigbee adds network structure, routing, and security to
complete the communication suite. On top of this wireless
engine, Zigbee profiles provide target applications with the
interoperability and intercompatibility required to allow
similar products from different manufacturers to work
seamlessly. IEEE 802.15.4 provides three frequency bands
for communications.
Zigbee also uses a DSSS radio signal in the 868 MHz
band (Europe), 915 MHz band (North America), and the 2.4
GHz ISM band (available worldwide). In the 2.4-GHz ISM
band sixteen channels are defined; each channel occupies 3
MHz and channels are centered 5 MHz from each other,
giving a 2-MHz gap between pairs of channels.
HARDWARE PLATFORMS OVERVIEW
An evaluating hardware was developed with Maxstreem,
xbee pro Zigbee module, it consumes only 2mW and 1.25
mW power at active and sleep mode. It is compatible to
transfer data upto 400 Meter range at 250Kbps. Zigbee pro
communicate based on DSSS (Direct Sequence Spread
Spectrum) and it’s very suitable to Mesh, point-to-point and
point-to-multipoint networks. it also gives 3V CMOS UART
option to interface External devices
like,microcontroller,sensors and etc.Xbee pro manufacturer
provide XTU software package to programme the xbee
module.
CONCLUSION
Industrial users should consider the type of monitoring
and control applications that are suitable for LR-WPAN
technology such as Zigbee. Reliability, security and
performance are potential challenges when designing and
deploying wireless technologies and factors such as
EMI/RFI and multi-path fading in industrial environments
can be specific issues to consider. Zigbee provides proper
network topology, and it overcomes all problems in
industries caused due to environmental issues[10]. We tested
Zigbee networks in various environmental conditions by
using four node star network for industrial applications like
speed and direction control of D.C motor, Illumination
control of incandescent lamp and closed loop water path
temperature control.
