Abstract:
The adoption of wireless communications based on Low-Rate Wireless Personal Area Network ZigBee technology (designed to control and monitoring in real time) in civil and industrial applications has increased rapidly in recent times. Due to several reasons include, low cost, low power consumption, ease of use and installation. In this thesis the establishment of a practical system for monitoring and remote controlling of temperature of power transformer using ZigBee wireless technology has been accomplished, the system will initially measure the temperature, and then sent these values to the centralized computer to calculate the required response to activate or de-activate the cooling fans of the power transformer. The system was established and designed by using a computer work station with graphic interface to control the phases of operation and communication; moreover, ZigBee wireless chips were used, in one side these chips have been connected to computer work station and on the other side it has been connected to microcontroller. Temperature sensors and light emitting diodes have been used to represent inputs and outputs of microcontroller. After installation and completion of all installation and programming works the system has worked successfully.
