PC BASED POWER PLANT PARAMETERS MONITORING t&
CONTROLLING USING X-BEE/ZIG-BEE [with front end]
ABSTRACT
The project is aimed to design a power plant automation system by using
wireless communication technology of ZIGBEE using which the manual operations can be
completely eliminated.
ZIGBEE is a specification for a suite of high level communication protocols
using small, low-power digital radios based on the IEEE 802.15.4-2003 standard for Low-
Rate Wireless Personal Area Networks (LR-WPANs). ZIGBEE is targeted at radio-frequency
(RF) applications that require a low data rate, long battery life, and secure networking.
ZIGBEE protocols are intended for use in embedded applications requiring low data rates and
low power consumption. ZIGBEEs current focus is to define a general-purpose, inexpensive,
self-organizing mesh network that can be used for industrial control, embedded sensing,
medical data collection, smoke and intruder warning, building automation, home automation,
etc. The resulting network will use very small amounts of power.
In this project, we will provide the automation by monitoring boiler
temperature and boiler water level. Here the wireless communication between the remote
areas can be achieved by using the ZIGBEE transceivers. On the transmitter side , Three
water level sensors will be arranged at 3 different levels of boiler and the temperature sensor
will be interfaced to the controller through an ADC to convert the analog value sensed into
the digital value. And an XBEE transceiver is also interfaced to the controller to transmit the
status of these sensors through a serial driver IC max232 for serial communication to takes
place. The controller continuously monitor the status of these sensors and passes the same
data to the XBEE module. So then it transmits the same data and it will be received by the
other XBEE transceiver which is interfaced to the other controller on the receiver side. And
then the transceiver passes the status of the sensors to the controller. So now the controller
will perform the predefined tasks by monitoring the received data. It turns ON the coolent

fan, if the sensed temperature crosses the set temperature value, and the pumping motor will
be turned ON and OFF based on the water level of the boiler. On the receiver side, to monitor
the status of the sensors a PC will be interfaced to the controller by using serial
communication technique. And we will develop a C# frontend application for the visual
effects, so the data can be visualized in the application itself without using hyper terminal.
This project uses regulated 5V, 500mA power supply. 7805 three terminal
voltage regulator is used for voltage regulation. Full wave bridge rectifier is used to rectify
the ac output of secondary of 230/12V step down transformer.
