Abstract
Our project is a novel approach in designing an automatic cradle swinging system for assisting infant care. This
equipment can be mainly used in the hospitals to provide an aid to the nurse in taking care of the infant or at home to monitor the
baby while the parent is at work and the baby is under the care of baby sitters. It has a cry analyzing system which detects the babies
cry pitch and accordingly the cradle rocks. At the maximum it could have six rocks per minute. If the baby doesn’t stop crying
within a particular instant of time a call or a message will be delivered to the nurse or to the parent’s mobile number via GSM , thus
intimating them that the baby has to be taken care of. In addition to this it has a wet sensor, temperature sensor and a respiration
sensor. If the baby wets an alarm or a display will be intimating in the case of wet sensor and for temperature sensor, if the baby’s
temperature rises above the normal body temperature then an alarm and a display message would intimate that the baby has to be
taken care of.
INTRODUCTION
In the current scenario where both the parents of a
family go for job, it has become very difficult for them
to take care of their kids. This finally results in giving
their child to a nanny who is assumed to take care of the
baby but at times things turn the other way round. Hence
here we have designed a system which would help the
parents in the child care. This design aims at 2 main
things in assisting parents.
WORKING
When the baby in the cradle cries, the cry will be
detected by the microphone where, sound signal will be
converted to electrical signals. 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. Microcontroller
controls the signals to be sent, then the output of the
microcontroller is sent to the drivers which drives the
DC motor and makes the cradle to swing according to
the sound intensity(baby’s cry). The wet sensor, which
is attached with the cradle sends signal to the signal
conditioning unit. There will be change in the resistance
when sensor detects wetness then this output is given to
the microcontroller and an alarm is set to alert the
parents . Respiratory sensor is used to check apnea
condition. On continous movement of the cradle , after a
particular time microcontroller sends an indication to 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. This number may be parents number
or nurse number
CONCLUSION
Thus the above designed system would be of great
use to the parents who go for job and to the present
development in the technology, the parents can have a
video interface and watch their baby LIVE via 3G!
Though we have designed such a system , we insist the
importance of baby care through our project.
