ABSTRACT
This project covers the design and construction of a Caller Location Tracking System for Police Distress call. The design helps the caller to make a ‘state of emergency’ alert to the police, during a distress situation that requires their urgent response, within a short period of time. This may as well be without the knowledge of anyone around and most of all alert the police of their urgent need in a specific location.
The location is traced with the use of a Google Map and Global Position System (GPS) details. It is to be noted that this service will be functional only to registered callers. The Research involves two segments; the transmitter’s end and the receiver’s end. The transmitter’s end involves the design of an alert button application designed for android phones. The application is dependent on the mobile Global Position System (GPS) which helps to identify the present location of the phone when the alert was sent. At the receiving end of this transmission, there is a GSM line receiving the alerts, and as well interfacing with an embedded device, designed for the purpose of extracting some certain information from the transmitter, (such as the sender’s GPS details and the sender’s phone number). All these are uploaded into a system having internet service so that there can be an adequate communication and data sharing between both ends of the network.
The successful conclusion of both segments of this research results in the transfer of geographical details of the user at the transmission end, to the receiver at the receiving end. Within the scope of time for performing some test to identify how successful this design was, a Success Ratio of 75 percent (75%) was achieved.
