Objectives:
1) To make a progress about my presentation and final report
2) To produce a good final report as a reference in the future
Method:
1) By making research in the internet
2) By using Microsoft Visio to produce a flowchart
The above flowchart shown was the Overall Process of the project development. The title of the project had been chosen at the first through the trusted website. The title obtained from the website was the Development of Smart Helmet by using Microcontroller. The literature review was carried out after the title selection. The background information of the project had been explained thoroughly in literature review section. The previous and present devices also had been discussed in this literature review so that the devices can be compared. Thus, the devices used in the project can be improved. Next, the circuit was designed by using Proteus and the coding had been written using KeilVision4 software. The program was saved in HEX file so that the circuit design can be simulated. If the circuit design and the programming had a success, the hardware implementation can be done after it but if the circuit design had an error, the circuit needed to be design and simulated again. After the simulation part had been success, the hardware implementation is the next process that need to be done. With the budget expected, the components had been bought and the circuit was constructed on a strip board. The program had been executed and burned into the microcontroller so that the result of the circuit can be obtained whether the circuit was functional or not. If the hardware implementation was a success, the demonstration and the project will be the next process that need to be done but if it was not, the circuit need to construct or check the wiring problem which may occurred during solder the components on the strip board.
The flowchart of the project development was above given. The given situation is when the motorcyclist had an accident only. When
the motorcyclist met with accident and had a crashed, the helmet hits the ground and the vibration sensor detects the vibrations that are created when the helmet hits the ground. The microcontroller detects the accident by using vibration sensor which is placed in the helmet. The microcontroller detects the accident occurrence and it will send an SMS containing information about the accident and location of accident using GSM and GPS modules. The
GPS receives the location of the vehicle that met with an accident and gives
the information back. This information will be sent to a mobile number through
a message. This message will be received using GSM modem present in the circuit.
The message will give the information of longitude and latitude values. Using
these values the position of the vehicle can be estimated.The GPS and GSM
module is running by using the microcontroller. Other than that, the alcohol sensor is used to sense the alcoholic content
whether the motorcyclist drunken or not. If the alcohol was detected, it gave information to the microcontroller to informed on LCD display the person is drunk. This will be a little bit help for the helper to know the condition of the motorcyclist.
Conclusion:
This week I learn how to produce a good flowchart. By using the Microsoft Visio software, it helps me to design the flowchart. By making researches in the internet, the flowchart need an explanation so that the readers will understand the flow of the project. The two flowcharts that I had made was the overall process to develop the project and the process flow during the situation that I decide to make.
