WIRELESS REMOTE based REMOTE ALIGNMENT OF 3D DISH POSITIONING -PROJECT

REMOTE ALIGNMENT OF 3D DISH POSITIONING BY WIRELESS REMOTE

The project is designed to develop a dish positioning system which can be operated by using an DTMF application. The main application of using a dish is to receive signal from satellites and other broadcasting sources. In order to position the dish to the exact angle to receive the maximum signal of a particular frequency, it needs to be adjusted manually.

In order to overcome the difficulty of adjusting manually, this proposed system helps in adjusting the position of the dish through an DTMF application device. Remote operation is achieved by any smart-phone/Tablet etc., with DTMF .

This system consists of two motors that enable the dish to move both in horizontal and vertical direction. The DTMF application device acts as a transmitter whose data is received by DTMF device which is interfaced to a microcontroller of 8051 family. The DTMF device sent data to the microcontroller which is transmitted from DTMF application device.

The microcontroller sends control signals to the motors through an interface IC also known as motor driver IC. The DTMF device Parallel communicates with the microcontroller.

The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is converted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.
