  1. Interactive Voice Response System (IVRS) Presented by Sateesh Kuna SrinivasraoDhavanam PrudhviBolli NirupCharan K Ashok Kumar M Under the guidance of Mr. B.Durgamalleswara Reddy B.Tech, Asst. Professor

  2. Introduction The main aim project is to improve the needs by providing the equipment in the home or industries we can control the devices by ON and OFF from any part of the world with mobile

  3. Literature Survey • GSM Mobile Phone • Mini Controller • IR version of Mini controller • Mini Timer • By Cybernetic concept

  4. Hardware Requirements • Micro controller (AT89S51) • Light Emitting Diodes(LEDs) • Power supply

  5. Micro Controller(AT89S51) • Features: • 4K Bytes of ISP Flash Memory • 4.0V to 6.6V Operating Range • Fully Static Operation: 0 Hz to 33 MHz • Three-level Program Memory Lock • 128 x 8-bit Internal RAM • 32 Programmable I/O Lines • Two 16-bit Timer/Counters • Six Interrupt Sources

  6. Pin diagram of AT89S51

  7. Micro Controller(AT89S51) contd.. • Microcontrollers are like single chip computers that are often embedded in to other systems to function as processing or controlling unit. • They are useful to communicate with other devices such as displays, sensors, buzzers to process input to a set of actions. • AT89S52 controller is selected because of inbuilt ISP (in system programmer) and in order to fulfill our applications

  8. Light Emitting Diodes(LEDs) Operation of a LED

  9. LEDs contd… • Low working voltages and currents • Less power consumption • Very fast action • Emission of monochromatic light • small size and weight • No effect of mechanical vibrations • Extremely long life

  10. Power Supply

  11. Power Supply contd… • Transformer • Rectifier • Filter • Regulator • Load

  12. Circuit Components • Micro Controller • APR9600 (Voice IC) • M-8870(DTMF IC) • Light Emitting Diodes

  13. APR9600(Voice IC) • FEATURES • Single-chip, high-quality voice recording & playback solution • Non-volatile Flash memory technology • User-Selectable messaging options • User-Selectable messaging options • Chip Enable pin for simple message expansion • Low power consumption

  14. APR9600(Voice IC)contd..

  15. APR9600(Voice IC) contd… • Functional description • Message management • General description • Playback in tape mode using auto rewind • Recording in type mode using auto rewind

  16. Message management Playback in tape mode using auto rewind

  17. Message Management Recording in tape mode using auto rewind

  18. DTMF M-8870 • FEATURES: • Low Power Consumption • Adjustable Acquisition and Release Tim • Central Office Quality and Performance • Power-down and Inhibit Modes (-02 only) • Inexpensive 3.68 MHz Time Base • Single 6 Volt Power Supply • Dial Tone Suppression

  19. DTMF M-8870 contd… Pin diagram

  20. DTMF M-8870 contd… • Functional description • Filter • Decoder • Steering circuit • Clock circuit

  21. Block diagram of IVRS MICROCONTROLLER Power supply AT89S51 DTMF receiver Voice IC Mobile

  22. Schematic

  23. Working Procedure • Interface DTMF 8870 with MC Port 2.0-2.4 pin • Interface APR9600 with port 1.0 of MC • Apply power supply to ground and Vcc terminals of AT89S51,APR9600 and M-8870 • Apply mobile connections to both voice and DTMF ICs • Connect devices to control to the port 3 pins of AT89S51 MC • Reset the microcontroller with RST pin of AT89S51 MC

  24. Applications • The ability to control lighting & household appliances • Easy controlling action of machines in an industry • Device controlling in Colleges and Schools • Monitoring of domestic appliances, home security and energy management • Easy to handle in office buildings, shopping malls and luxury homes

  25. Advantages • Easy interaction to the users • Less cost and easy to install • Easy to maintain • Remote based controlling of devices in home • Communication to our devices from all parts of the World • Secure in critical applications

  26. Conclusion Finally we conclude this system that would help for the good interaction of user with the heard voice (in mobile) and responding to it as per his need so that the user can automated the devices in homes, industries.

  27. Future scope • SMS based system • Helpful in low signaling areas • As the number of devices increases delay increases and cost of call also increases • Noise and disturbance not occurred by sending SMS

  28. THAN'Q'UERIES ?
