This project aims to create a wireless transmission of data to a bulletin board for announcements, advertisements and posting of any kinds of informative statements that will be useful for readers, employees and students.
2.1 Problem Statement
Electronic bulletin board cannot update information time by time. Our system can provide ready-made templates so that time by time, we can change the appearance base on the activity to be posted. Especially the proponents device can provide a wireless transmission of data to bulletin board with different displays.
To achieve the goal, the proponents will be addressing the following problems.
2.1.1 General Problem
How to create a PC based Bulletin Board with Wireless Digital Display System?
2.1.2 Specific Problems
220.127.116.11 How to create a wireless device that can send data from a computer to a monitor?
In updating the posts in the bulletin board, the in-charge personnel need to go over the bulletin board personally just to change and update the posts. 18.104.22.168 How to create the software for the messages to be displayed?
In manual updating of information in the bulletin board, the posts should be printed in the paper before posting. 22.214.171.124 How to create log-in module system for the security of the user?
Unauthorized person could access the information to be posted in the bulletin board. 126.96.36.199 How to create a module that can control the messages to be displayed?
It consumes time updating the information to be posted in the bulletin board, the authorized personnel is required to update the post in a timely manner.
2.1 Proposed Research Project
2.2.1 General Objectives
To create a PC based Bulletin Board with Wireless Digital Display System.
The proponents will create a device that provides a wireless transmission of data to bulletin boards with different display.
2.2.2 Specific Objectives
188.8.131.52 To create a wireless device that can send data from a computer to a monitor.
The proponents will be using a Wi-Fi router for the transmission of data for the LCD display and will create a RF transmitter for the transmission of data for the LED display. 184.108.40.206 To create the software for the messages to be displayed.
The proponents will be using Flash Software for the manipulation of the messages to be displayed in the bulletin board. 220.127.116.11 To create log-in system for the security of the users.
The proponents will create a log-in system by using Visual Basic 6.0 for the security of the bulletin board. 18.104.22.168 To create a module that can control the messages to be displayed.
The proponents will create a module using Visual Basic 6.0 that can control multiple displays in the bulletin board.
2.2.3 Scope and Limitations
* The system can accommodate multiple displays with a single controller. * The system can display static and scrolling messages.
* The system can stream videos through a wireless transmission. * The system has a default screen messages.
* The information to be displayed is queued.
* The controller sends information in an LCD and LED display wirelessly.
* Distance of the controller from the monitor is limited. * Editing of messages is done manually by a duly authorized person. * This bulletin board is for indoor purposes only.
The proponents will be using the cycle of PROTOTYPING METHOD to accomplish the project.
a. Requirements Analysis
A prototyping model begins with requirements analysis, and the requirements of the system are defined in detail. The user is interviewed in order to know the requirements of the system.
When requirements are known, a preliminary design or quick design for the system is created. It is not a detailed design, however, and includes the important aspects of the system, which gives an idea of the system to the user.
c. Paper Design
Information gathering from quick design is modified to form a prototype. It represents a rough design of the required system.
A partially developed product that enables customer and developers to examine some aspect of the proposed system and decide if its suitable or appropriate to the finish product.
The process of combining ideas into a congruous object of thought that based on the paper design. Satisfying certain conditions as part of solving a problem.
f. Unit and integration testing
The phase in software testing in which individual software modules are combined and tested as a group. It occurs after unit testing and before validation testing. Integration testing takes as its input modules that have been unit tested, groups them in larger aggregates, applies tests defined in an integration test plan to those aggregates, and delivers as its output the integrated system ready for system testing.
g. System testing
Document Settings must be defined where each types of documents types consists its custom made layouts that suits business processes. Basically document layouts setup or linked to the documents setting are default document layout that are standard layout that complies with the companys standard business process.
h. Acceptance testing
Testing generally involves running a suite of tests on the completed system. Each individual test, known as a case, exercises a particular operating condition of the users environment or features of the system, and will result in a pass or fail, or Boolean outcome. There is generally no degree of success or failure.
i. Operation and maintenance
In production, system requires updates, changes and maintenance from time to time so system can work properly. This phase goes on for entire life time of the system. [PFLET998] (Fig 1.0 sees at Appendix B)
