1.ABSTRACT:
Wireless networks have been very popular research field for the last
couple of years. XBee is a new technology now being deployed for wireless
sensor networks. XBee is a low data rate wireless network standard defined by
the XBee Alliance and based on the IEEE 802.15.4.The XBee wireless network
has some advantages compared
with other wireless networks, it has the
characteristics of low power, low price, highly secured and reliable, so
implementing a remote motor control and monitoring system proves to have a
good cost performance ratio.
2.OBJECTIVE:
In recent years, wireless sensor networks have widely spread in many
areas including industrial data transfer and process control applications. In the
present days Automated systems have less manual operations more flexibility,
reliability and accuracy. Due to this demand every field prefers automated
control systems. Especially in the field of electronics automated systems are
giving good performance. And this is realized by making use of XBee
technology for communication. XBee is new wireless technology guided by
IEEE 802.15.4 Personal Area Network standard. It is primarily designed for the
wide ranging controlling applications and to replace the existing non-standard
technologies.

4.METHODOLOGY:
A general block diagram of the proposed scheme is given in Figure .The
whole system is divided into two parts-transmitter and receiver. In the transmitter
part a key input is provided to control the speed of the DC Motor present at the
plant location .The pressed key input is simultaneously fed to the ARM7. This is
transmitted efficiently and smoothly to receiver end through wireless XBee
Communication Protocol (IEEE802.15.4 Standards). The ARM7 at the transmitter
end is so programmed that to identify pressed key for the DC Motor come out of
the desired or safety limit, a signal will be generated by the ARM7 . All the
processor and controllers are interconnected through XBee. An 32-bit ARM
Processor has been used to interface the IEEE 802.15.4 standard, XBee protocol.

7.CONCLUSION:
This proposed controller successfully operates wirelessly with a
distance of 70 meters between the controller. More over any change to the
controller can be incorporated to the design and realized in hardware rapidly.
Thus, it is easily possible to customize the controller for any industrial
applications. Comparing to other technology, the proposed controller is relatively
simple, low cost and can be reprogrammable. In addition, the architecture has
been expanded to control more than one motor at one time by addressing
technique.
