ABSTRACT

v Wireless mediums are the latest technology

developments and the primary reason being the wiring

space and clean look.

v Due to increase in technology and the innovations

there are some issues for child safety, the child needs

to be protected from the hazards. So the introduced a

technology called child safety management using

R.F technology.

v Child safety management system is a

specialized field dealing with protection

of child at a particular place with the

usage of easy-to-use technologies for 

security and comfort.

v RF Technologies has made infant

abduction prevention straightforward:

Safe Place Infant/Child gives you, and

the child’s parents, the peace of mind

v In fact, any attempt to tamper with

system wiring or tags by unauthorizedpersonnel will send an alert to themonitoring system

CIRCUIT DESCRIPTION

Ø

The circuit built around transistor T1(BF494) is a basic low-power variable-frequency VHF oscillator.

Ø A varicap diode circuit is included to

change the frequency of the transmitter and to provide frequency modulation byaudio signals. The output of theoscillator is about 50 milliwatts.

Ø Transistor T2 (2N3866) forms a VHF-class A power amplifier. It boosts theoscillator signals’ power four to five

times. Thus, 200-250 milliwatts of power

OPERATION:

1. in this project the child safetymanagement has been achieved withRF Technology. 2. There will be a RF band to thechild with a transmitter connectedwith the band, which transmits theinformation of the child through theRF chip.

3. The RF Receiver at the other end willreceive the data continuously and store it

in database. As such child is continuouslymonitored through the receiver, 4. if the child crosses the prescribed limit

which is bounded i.e. the receiver couldn’ttrack the information of the child then itwill trigger an alarm to the person incharge, then they can take the requiredactions.

ADVANTAGES:

It is reliable.

It is very simple to control.

Easy to handle.We can operate the home appliances and

devices remotely through the RF technology.

We can operate the devices securely withoutany intrusion.

APPLICATIONS:

This system can be used for safety of child any where.

In child Hospitals, busy Roads, Apartments, Child care centers etc.
