WEEK 10 - FINDING ON COMPONENTS AND DEVICES USE

GSM Modem

A GSM modem is a device which can be used by a computer or any processor to communicate over a network. It requires a SIM (Subscriber Identity Module) card to operate and operates over a network range subscribed by the network operator. It can be connected to a processor through USB, serial or Bluetooth connection. A GSM modem exposes an interface that allows applications such as SMS to send and receive message. Message sending and receiving was performed directly on a mobile phone and charges by the mobile operator. To perform these tasks, a GSM modem must support an “extended AT command set” for sending/receiving SMS messages, as defined in the ETSI GSM 07.05 and3GPP TS 27.005 specifications. GSM modems can be a quick and efficient way to get started with SMS, because a special subscription to an SMS service provider is not required. 

GPS Module

The Global Positioning System (GPS) Receiver Module is a low-cost, fully integrated with on-board patch antenna which provides standard, raw NMEA0183 (National Marine Electronics Association) information or specific data, such as latitude, longitude, altitude, current time, date, speed, and travel direction through a serial interface. The GPS able to calculate the position and time accurately when it receives the data from each satellite. GPS systems contain three segments; GPS satellites, ground control stations and GPS receiver. GPS able to work when signal of time is first sent from GPS satellite at a given point. Then the time difference between GPS time and point of time clock when GPS receiver receives the time signal is calculated to generate the distance from receiver to the satellite. 

Microcontroller 

This system using Arduino as microcontroller to work on this safety device. It is an open-source platform used for building electronics projects. Arduino consists of both physical programmable circuit board can be referred as a microcontroller) and a software, or IDE (Integrated Development Environment) that can be runs with computer to write and upload computer code to the physical board.

WEEK 8 - ATTENDED 3RD FYP 1 BRIEFING & BLOCK DIAGRAM

3RD  FYP 1 BRIEFING
Date : 12th April 017
Time : 3-5 pm
Venue: TTL 2

This briefing is focusing on workshop for Methodology and Results & Discussion Writing for FYP Report presented by Dr. Imran Mohamad Sofi.

Dr. Imran explained on how to write methodology by highlighting block diagram, flowchart and plan layout.  I able to write chapter 3 with guide provided. 

This week i am focusing on my block diagram for this project by identify the input, processor and output. This is my block diagram for this project:

The block diagram shows GPS module as the input and GSM modem as the output for this project. Arduino is uses to process the data.

WEEK 7 - OBJECTIVE, PROBLEM STATEMENT & SIGNIFICANCE

OBJECTIVE

The main purpose for this project is to develop a safety device for people who suffer from Alzheimer disease. The objectives of this project are:

• To develop a prototype of safety device for Alzheimer’s Patient by using GPS and GSM.

• To design a programming to integrate GPS and GSM system.

• To introduce safety device that is effective and benefits to the user.

PROBLEM STATEMENT

Nowadays, missing cases related to Alzheimer’s patients become a growing concern across the world. By increasing population  of elderly or senior citizen in Malaysia, Alzheimer disease also growing as this disease commonly affect individual at age over 65 years. They suffer from memory loss where they tend to forget everything around them such as dates, places and even their name. They cannot adjust to a new environment and tend to wander around if left alone. Thus, the probability of them went missing without trace is high. Their family members or caregivers could have rough times to find them as they did not know their whereabouts and it is hard to track them if the patients have gone too far from their last seen location.

SIGNIFICANCE OF THE PROJECT 

By developing the safety device for Alzheimer’s patients, this system could be beneficial as one of the method to track the missing patients. In traditional way, people usually searching them all over the place by asking people nearby or spread the news about the missing patient. This method going to take a longer period before the patient can be found and worst situation might be happened between that time. This safety device equipped with GPS and GSM that installed in patient’s shoes will allows real-time location to be send to the caregiver, thus they can go straight up to the location. The device help in reducing time for searching process, thus unwanted situation happens to the patient could be avoided. This safety device also work to monitor the patient. Caregiver who cannot give their full attention to the patient can always monitor their movement. They can keep the location updated to know the patient’s whereabouts. 

WEEK 6 - ATTENDED 2ND FYP 1 WORKSHOP & BACKGROUND OF THE PROJECT

2ND FYP 1 WORKSHOP

(Workshop on Introduction and Literature Review Writing)

Date : 29th March 2017

Time: 3-5 pm

Venue: TTL 2

This briefing is focusing on workshop for Introduction and Literature Review Writing for FYP 1 Technical Proposal presented by Dr, Siti Marwangi Binti Mohamad Maharum. By attending this workshop, I able to write my chapter 1 and 2 with guide provided. 

This week I am focusing on my research for my background project on what is Alzheimer's an what is my purpose this project. 

From my finding, Alzheimer's is one of the common form of dementia which is a disease that can reduce mental ability of the patients. It cause problem to memory, thinking and behaviour. Most of the Alzheimer’s patients suffer memory loss, trouble to communicate and having a hard time to carry out daily activities etc. Patients who suffer from Alzheimer may forgotten their name, family and even their surroundings due to the memory loss. They often wandering and confuse when they are alone. They can go missing if no supervision from caregiver. 

I also make a study on missing cases related with Alzheimer'. There is a case reported by Sinar Harian newspaper on 28 August 2013 where elderly woman age 75 who suffers from Alzheimer went missing from her house when she went out to buy some groceries at store nearby in Rawang.  A research that i found states there were 93 cases where Alzheimer’s patients found dead in United States from 1998 to 2002 after leaving their caregiver unattended. 

Thus, the purpose for this project is to develop a safety device that can monitor their location and track them when they went missing. This device equipped with Global Positioning System (GPS) and Global System for Mobile communication (GSM) that could help to give a real-time location of the patient to the caregiver. The system uses geographic position and time information from the Global Positioning Satellites. Longitude and latitude of the location are reported by SMS message. This device is installed in the patient’s shoes and this help to monitor their whereabouts and keep them in track.
