ABSTRACT
This project is about making an embedded system in order to control different functionalities of a DC / AC Motor with PC using wireless RF technology. The main functions of this DC / AC Motor are to control the speed and direction.
The whole hardware consists of two parts. One is the transmitter side and the other side is the receiver side. The transmitter side consists of PC, Encoder, a microcontroller and RF (Radio Frequency) transmitter. On the receiver side there is an RF receiver, a decoder, a microcontroller, a motor driver and a DC / AC Motor
During this project a wireless system is going to be used to enhance the DC / AC Motor operated manually. This system will actually adapt the requirements of the modern technology. With the help of this system one can control the speed of the DC / AC Motor controller from remote sites. It can also control the direction of the DC / AC Motor. In order to make it user friendly we make a GUI for controlling it from the PC. The data is sent and received via transmitter and receiver respectively.
This data will be encoded and decoded and sent to the motor driver from where it is sent to the DC / AC Motor in order to perform the operations
INTRODUCTION
The main aim of this project is look after the various problems arised in industries and are controlled using wireless networks like RF Microcontroller
RF Microcontroller is an emerging short-range, low-rate wireless network technology.
RF Microcontroller can be used to minimize power consumption and promote long battery life in battery-powered devices.
RF Microcontroller provides all suitable data rates as compared to other wireless technology so this withstands suitably for such applications.
SOFTWARES USED
The softwares used are
keil software
MAT LAB software
Keil was founded in 1982 by Günter and Reinhard Keil, initially a German
Cleve Moler, the chairman of the computer science department at the University of New Mexico, started developing MATLAB in the late 1970s
INTRODUCTION TO RF MODULE
RF Module is a low-cost, low-power, wireless mesh network standard.
The low cost allows the technology to be widely deployed in wireless control and monitoring applications.
Low power-usage allows longer life with smaller batteries
The RF Module network layer natively supports both star and tree typical networks, and generic mesh networks
RF Module is designed as a low-cost, low power, low-data rate wireless mesh technology.
EXPERIMENTAL SETUP
The proposed project research industrial machineries will be controlled & regulated by the switching actions RF Receiver
Why RF MODULE?
Reliable and self healing
Easy to deploy
Very long battery life
Secure
Low cost
Can be used globally
DC MOTOR
MAX232
The MAX232 is a dual driver/receiver that includes a capacitive voltage generator to supply
LOGIC DIAGRAM:
The MAX232 has two receivers (converts from RS-232 to TTL voltage levels) and two drivers (converts from TTL logic to RS-232 voltage levels).
MICROCONTROLLER
Microcontroller, as the name suggests, are small controllers. They are like single chip computers that are often embedded into other systems to function as processing/controlling unit
Features OF 89S52
The 89S52 is an microcontroller with 64 kB Flash and 256 bytes of data RAM.
CIRCUIT DIAGRAM
APPLICATIONS
Modern factories depend vastly more on automation and intercommunication through this wireless network
In addition to enabling factory monitor and control functions, RF Module provides the ability to track and locate raw materials or finished products as they move in, through and out of the facility
ADVANTAGES:
wireless mesh network• terminal equipped with a multiple of interfaces • can develope thousands of nodes• high coverage with low costs• possibility of using integrated antennas• very low operations costs compared with other wireless technologies• very low power consumption
FUTURE WORK
RF Microcontroller is the global wireless language connecting the dramatically different devices found in commercial buildings.
With so many major companies recognizing it as the clear choice to build the foundation for wireless building automation
. Hence Industrial automation will demand the wide scope to utilize RF Microcontroller for improve control & operations in terms of Power Monitoring System.
CONCLUSION
Industrial users should consider the type of monitoring and control applications
RF Microcontroller provides proper network topology, and it overcomes all problems in industries caused due to environmental issues
. In future we can also test other RF Microcontroller networks for proper wireless data communication
