SYNOPSIS
  • There is a need to develop a new low cost
    indigenous electronic cradle because the existing
    cradles are imported and costly. Final year ece
    projects in chennai ,bangalore ,vijayawada,kakinad
    a. This paper presents the design and
    implementation of a new indigenous low cost Baby
    Cradle that swings automatically when baby cries,
    for this it has a mobile phone video analyzing
    system which detects the baby cry video with
    audio and accordingly the cradle swings till the
    baby stops crying. The speed of the cradle can be
    controlled as per the user need. The system has
    inbuilt alarm that indicates two conditions
    first when the mattress is wet, which is an
    important parameter to keep the baby in hygienic
    condition, second when baby does not stop crying
    within a stipulated time, which in turn
    intimated that /www.embeddedinnovationlab.combaby
    needs attention. / .This system helps parents and
    nurses to take care of babies without physical
    attention.

INTRODUCTION
  • Since the evolution of humans , mothers play an
    important role in taking care of children. Final
    year embedded system projects in chennai
    ,bangalore,vijayawada,kakinada.
  • But parents in the present world are busy in
    their professional life.
  • The system is designed to help parents and nurses
    in infants care.
  • The project intimates the care takers by sending
    both alert message as well as video and audio
    calls when a baby cries.
  • www.embeddedinnovationlab.com
  • Parents can control the cradle movement with a
    keypad press.
  • Respiratory sensors and Wet sensors are also used
    to detect respiratory rates and wetness
    respectively.
  • Thus this project is a solution, for parents at
    home who lose sleep over a baby who constantly
    wakes up and cries.

6
Working
  • When the baby in the cradle cries, the cry will
    be detected by the microphone.
  • The signals are then amplified by the amplifier
    then it is sent to the peak detector where cry
    peaks will be detected and further the signal is
    sent to microcontroller. Final year mechanical
    engineering projects in chennai,bangalore,vijayawa
    da,kakinada
  • Sensors used
  • Wet sensor.
  • Temperature sensor.
  • Respiration sensor.
  • The GSM modem via RS232 interface, the modem
    will send a message or a call to the mobile
    number stored in the modem as an alert.
  • www.embeddedinnovationlab.com
  • Using the Skype technology can observe the video
    of the baby.
  • Control the Cradle movement.

Design Aims
  • When baby cry parent can automatically swings
    the cradle till the baby stops crying.
  • Final year mechanical projects in
    chennai,bangalore,vijayawada,kakinada
  • Alerts the parent when the mattress gets wet.
  • Alert parent by giving temperature as well as
    respiration rate by of SMS.
  • Alerts the parent by giving call or sending
    SMS.
  • The parents can have a video interface and watch
    their baby LIVE via 3G! SKYPE TECHNOLOGY.

LITERATURESURVEY
  • Steven Bang
  • Steven Bang designed automatic baby rocker having
    a noise sensor to detect baby cry. Noise sensor
    consists of Electret MIC with a pre amplifier
    (2n3904 transistor). Signal from noise sensor is
    fed to microcontroller which is used to control
    the DC motor. Final year engineering projects in
    bangalore,chennai,vijayawada,kakinada. Few
    colorful lights made up of LED are used to
    entertain the baby while being rocked.

LITERATURESURVEY
  • Yang Hu
  • Yang Hu proposed an algorithm for adjusting the
    bassinet swaying extent by the sensor signals.
    The bassinet is made up of an adaptive swaying
    device and other sensors network. While baby is
    crying, the sensors network can judge the reason
    according to detecting parameters, giving the
    different signals to control circuit. At the same
    time, the bassinet starts to sway slightly. The
    swaying rhythm can be adjusted according to
    parameters from baby status. 2.

LITERATURESURVEY
  • Marie R.Harper
  • Marie R. Harper invented a crib adapted to be
    rocked automatically. Once the crib is manually
    tilted in one direction and released, this
    permits the inertia to actuate the locking and
    actuating arms to operate under the biasing force
    of spring in conjunction with the gear. Thus
    spring loaded motor begin to operate and the
    lever arm is oscillated in back and forth
    movement. This provides the same effect as would
    be achieved by the mother rocking the crib
    containing the baby. Oscillation of crib is
    stopped when the slightest resistance is incurred
    3.

LITERATURESURVEY
  • Gim Wong
  • Gim Wong presented an Electronic device that can
    be attached to conventional pivotally mounted
    type crib. Which is actuated by baby cry voice
    picked up by the microphone giving short throw
    type rocking action to crib. Very similar to a
    person rocking the crib by pushing and pulling on
    the foot or headboard . There is a sensitivity
    control so that baby voice only actuate the
    rocking action and a timer to controller the
    duration of rocking action 4.

12
LITERATURESURVEY
  • Chua-Kai-Hsieh
  • Chua-Kai-Hsieh proposed a baby cry recognizer
    which includes an amplifier circuit for
    amplifying a received sound signal. In response
    to the amplified sound signal, a pulse generator
    circuit generates a pulse signal having zero
    crossings which are aligned with zero crossings
    of the amplified sound signal. The pulse signal,
    in turn, is inputted to a signal recognition
    circuit. The signal recognition circuit outputs a
    signal indicating that a babys cry was detected
    5.

LITERATURESURVEY
  • Anritha Ebenezer
  • Anritha Ebenezer gives an approach to design a
    baby cradle consisting of cry analyzing system
    which detects baby cry. According to sound
    intensity cradle swings. It has six rocks per
    minute. It has wet sensor to indicates baby wets,
    www.embeddedinnovationlab.comwhenever baby wets
    resistance would change thus sending a signal.
    Other sensors include temperature sensor to
    display baby temperature, respiratory sensor that
    sends a signal in apnea condition. GSM modem via
    RS232 is used to send message to parents in case
    baby does not stop crying with in a particular
    instant of time 6.
