Zigbee-Based Automatic Phase Changer Based on Microcontroller

Abstract

To keep up with the ever-changing demands of today's world, every system is now fully automated. Because of the reduced need for human intervention and the increased precision and reliability of automated systems, these control systems are in great demand across all industries. Exceptional performance is the duty of automated systems, especially in the electrical and electronics area. The electrical industry now uses a manual process to switch from one phase (three phases) to another (single phase). I would want to automate the transition from three phases to one phase in the event that the voltage in any two of them drops too low. So, we
came up with a solution: a system that uses wireless technology to monitor and alter phases, thereby solving the issue. The article Automatic phase change and monitoring based on embedded systems employing ZIGBEE ensures security, delivers excellent dependability, and is prone to many errors. The system employs a microprocessor to manage its transmitter and reception sections. The ZIGBEE transmitter and receiver portions communicate with one other. On the computer, you may see the current monitoring phase. Automatically convert a three-phase system to a single-phase one if voltage drops below a certain threshold in any two of the
phases. Family by microchip, Atmel 89cxx, 89cxx51. The microcontroller make use of this project is PIC16F877A. Now a day, several times out of three phases one of the phase cuts off manually. The day to day life of human being, the circumstances which occur due to power instability issues we decided to design such a system which would overcome this issue eventually and aid to reduce human efforts too. Secondly in order to overcome the various phase change issue and avoid damages. We can change the phase automatically and monitor the present phase electrical line through wireless sensor networks (WSN) provide self organization and local processing capability and will be displayed in PC (own Computer). ZIGBEE network is used at this point. These permit the configuration of a great network of sensors in different industrial segments. In evaluation with the other standards such as WI-FI and Bluetooth, the ZIGBEE standard has advantages related to power consumption, low cost and scalability. In our project, low voltage of phase is varied through potentiometer and then the results are displayed in LCD (Liquid Crystal Display).
