Bluetooth is the buzz word, while designing any automation system for study purpose. Automation of Home/Work place is common using short range communication technology, called Bluetooth. This is because it is hard to change the position of the Antenna frequently to get good signals, which usually fitted at uncomfortable height/place. The Bluetooth enabled Android Mobile Phone can be used as remote control device and control the antenna direction by standing at safe and comfortable place.
Objective: The construction of system which allows user to control direction of the antenna standing at safe and comfortable place. Note that getting current status of the controlling antenna can also be implemented with slight code and hardware change at both ends.
This Antenna Position Control System has two parts: User end who uses Android App on his Android Mobile to send command to control direction of intended antenna via Bluetooth means; and Control end where controlling antenna is connected with main controller unit [which also decodes Bluetooth received commands and act accordingly]. The controller module is based on popular 8051 microcontroller chip. Its memory resident program/code monitors its Bluetooth module over its UART port or serial port for any user commands. If any data found at serial communication (UART protocol) pin, it is decoded as positioning command and accordingly executed on output port connected antenna. The output port connected Display Module shows current status of the system and antenna switching state.
This system allows user to control three parameters: Change in Number of Steps, Direction either Clockwise or Anti-clockwise and Speed variation to choose from three categories such as Low, Medium or High.
Note that DTMF technique can also be used to control antenna positioning at home/work place without touching actual antenna and its accessories.
The intended device needs Android App in user Android mobile hand set prior using this system. The range of the system is defined by used Bluetooth's communication range.
Since only small antenna positioning motor is controlled, less care needed while designing and controlling system.
Applications:
- The system is used as wireless remote controlled Antenna Positioning System at home/work-place.
- Since single point control is possible, useful for non-technical people.
- Since system is embedded type and wireless, portability is done very easily. Changing controlled/positioning antenna’s all three parameters is very easy.
