Child Tracking System
Abstract
The C Tracker is an intelligent application that ultimately aims for the prevention and protection against child abuse and to ensure their safety and security; especially for the school going ones. The most important part of the proposed system is a smart watch that ensures the safety and provides security to the child by using an SOS button. Also it keeps track the locations of the child for further verification and references.
The child application will send notifications to the parent application and to the saved official numbers that includes the location and picture of the child’s surroundings in case of any trouble so that the associated ones can take necessary actions as soon as possible. The very important advantage of the system is that, the parent will receive alert message to their preset phone number even if the parent is offline. Also, the application provides the facility to send a pre-alert message to the saved numbers in case, if the child feels any source of insecurity.
Introduction
The app named C-TRACKER. By this mobile app,we have covered all these aspects by using a special watch.The watch is provided with an SOS button located on the side of the watch, which triggers the panic mode when pressed. On activation of the panic mode, the camera attached to the watch clicks the pictures of the surroundings and the GPS module collects the location coordinates of the kid and transfer the same to the parent app and to the official numbers that are saved in the child app. Geo-coding and reverse geo-coding are the technologies that are applied here. Geo-coding is the process of converting addresses (like a street address) into geographic coordinates (like latitude and longitude), which you can use to place markers on a map, or position the map. Reverse geo-coding is the process of converting geographic coordinates into a human-readable address.
The camera module attached to the special watch is used to capture the pictures of the surroundings when the panic mode is on. The camera will turn on only if the SOS button is pressed. The camera consists of a lens which focuses light from the scene and it is this picture that is send to the parent’s app. Here, there is a 2.0 MP camera which helps you to take stunning pictures. The camera is capable of 2592 x 1944 pixel static images, and also supports 1080p30 and 720p60. Here the parent is referred to as the remote user. They will be the one who is receiving the GPS coordinates and the image of the panic situation via notifications to the corresponding application. When the SOS button is pressed the GPS coordinates and the background images of the student are sent to the parent’s app.
SYSTEM ARCHITECTURE
The GPS receiver module that is being worn by the child is continuously receiving the signals from the satellites. These satellites are located in the sky and continuously send data down to earth over respective RF frequencies.GPS receivers have tiny processors and antennas that directly receive the data sent by the satellites and compute the position and time. The receiver module contains an SOS button that triggers the panic mode when pressed.
On activation of the panic mode, the camera attached to the watch clicks the pictures of the surroundings and the GPS module collects the location coordinates of the student and transfer the same to the parent app and to the official numbers that are saved in the child app. Before sending these details to the parent app and to the official numbers, these information are saved in the database of the server. Also, there exist a provision for the child to send a pre-alert message to the parent incase if he/she feels any sort of insecurity.
SOLUTION METHODOLOGY
Initially, the SOS button is not active.
When the student feels any sort of insecure feelings he/she can press the SOS button.
So, here the status of the button is always checked.
When the button is pressed, the GPS module and the camera module will turn on.
The GPS coordinates and the background image of the student’s surroundings are captured within a delay of approximately five seconds.
The data will be sent to the parent via a notification to the parent’s app.
ALGORITHM
Child tracker ( )
{
// child side ( )
E_no = get the emergency number // initialize emergency
number to E_no.
O_n1 = get the number of first official
O_n1 = get the number of second official // initialize
official numbers to O_n1, O_n2.
Loc = get the GPS co-ordinates // initialize the GPS coordinates
to Loc.
Image = capture the image // initialize the captured image
to Image.
On click (SOS Button)
{
Display ( Loc, Image) // display location and image on
E_no and location on O_n1 and O_n2.
Call ( E_no) // call to the emergency number.
}
On click (prealert)
{
Display (loc)// display location on E_no.
}
//parent side
No = Enter the parent number // initialize the parent
number to No.
Display (loc, image) // display location and image on
E_no and location on O_n1 and O_n2.
