Title: Interactive Voice Response System For College Automation (IVRS)

Interactive Voice Response System For College
Automation (IVRS)
Introduction What are interactive voice response
(IVR) systems?
  • The Interactive Voice Response (IVR) System
    serves as a bridge between people and computer
    databases by connecting the telephone
    network with the database. The telephone user can
    access the information from anywhere at anytime
    simply by dialing a specified number and
    following an on-line instruction when
    a connection has been established. The IVR system
    uses pre-recorded or computer generated voice
    responses to provide information in response to
    an input from a telephone caller

Interactive Voice Response System For College
Automation (IVRS)
  • Now-a-days every institution needs
    automation. As a part of college automation,. In
    the hardware side embedded system has been used.
    A 20 pin microcontroller 89C2051 is used because
    of its compatibility with our hardware. This
    microcontroller controls the whole hardware.
    Telephone line is used for communication purpose.
    Visual Basic has been used for software
    programming. Presentation in the class and
    outcome of the university are made reachable to
    the parents by our project. It will be very
    obliging to the parents to be acquainted with
    their son's/daughter's recital in the college

Power supply In this system we are using 5V
power supply for microcontroller of Transmitter
section as well as receiver section. We use
rectifiers for converting the A.C. into D.C and a
step down transformer to step down the voltage.
The full description of the Power supply section
is given in this documentation in the following
sections i.e. hardware components.
  • MICRO CONTROLLER (AT89S51)?The AT89S51 is a
    low-power, high-performance CMOS 8-bit
    microcontroller with 4K bytes of in-system
    programmable Flash memory. The device is
    manufactured using Atmels high-density
    nonvolatile memory technology and is compatible
    with the industry standard 80C51 instruction set
    and pin-out. The on-chip Flash allows the program
    memory to be reprogrammed in-system or by a
    conventional nonvolatile memory programmer. By
    combining a versatile 8-bit CPU with in-system
    programmable Flash on a monolithic chip, the
    Atmel AT89S51 is a powerful microcontroller which
    provides a highly-flexible and cost-effective
    solution to many embedded control applications.

  • Voice IC (APR 9600) This device will receive the
    signal of human voice through mike. It is having
    28 pins on its IC. It consists of 8 message lines
    (or channels) to which we can give a voice
    message and it can operate in any one of two
    modes (recording and playback). The supply pins
    are connected to power supply circuit. Analog
    (AGND) and digital ground (DGND) pins of voice
    decoder IC are connected to VSS of power supply.
    Analog power supply. All the voice channels pins
    are connected to the port1 of microcontroller.

    full DTMF Receiver that integrates both band
    split filter and decoder functions into a single
    18-pin DIP or SOIC package. Manufactured using
    CMOS process technology, the M-8870 offers low
    power consumption (35 mW max) and precise data
    handling. Its filter section uses switched
    capacitor technology for both the high and low
    group filters and for dial tone rejection.

  • EEPROM 24C02 ?The project Smart Card based
    Library Management System makes use of smart
    card technology to provide authentication. The
    Smart card is taken as a means of authentication
    with the details like student name, id of book
    being taken by the student etc stored on it. But
    in order to give id s to all the books available
    a memory is required. This requirement is
    fulfilled by making use of EEPROM.
