BUILDING IVR FRAMEWORK THROUGH ASTERISK FOR CONTROLLING HOME APPLIANCES

In this technological era, mobile phones are very much essential entity in everyone's life and the mechanisms for remote controlling of different tasks in different domains through the mobile phones are also widely accepted all over the world. With this approach, one can design a robust and efficient mechanism by introducing a framework for controlling the home appliances remotely through phone calls from any corner of the world. This work is to design and development of an Asterisk based Interactive Voice Response (IVR) platform that allows the inhabitants to access and control the status of their home appliances remotely. In this IVR based platform, a Bluetooth enabled mobile phone is connected to the system; a computer system which is acting as the Asterisk PBX server. Hence, inhabitants are able to make a call to the Bluetooth enabled mobile phone and then he/ she will be redirected to the server to offer the IVR based platform, through which he/ she will be able to give his/ her choice of actions to be performed over the appliances. A ‘homecontrolsystem' database is also maintained in the server to store the user PIN and other information, so that only registered users can access the system. Once a registered user inputs his/ her commands over the IVR platform, the system will forward the commands to the 8051 microcontroller by using the serial port communication and the actions will be performed accordingly over the actuators. For the simplicity, status of LEDs has been observed in the designed prototype in spite of the actual home appliances.
