ABSTRAK

Papan pengumuman adalah satu perkara yang penting di sekolah dan kolej. Sekiranya ada pengumuman yang perlu disampaikan kepada semua pelajar, orang yang menjaga papan pengumuman perlu menukarkan pengumuman yang terbaru. Masalah papan pengumuman wujud adalah ia memerlukan operasi manual dan sukar untuk mengendalikan. Projek ini adalah mengenai reka bentuk dan pelaksanaan papan pengumuman, dimana ia boleh menghantar mesej dengan menggunakan GSM. Projek ini berdasarkan memapar maklumat di atas papan matriks LED oleh mana-mana destinasi di dunia melalui rangkaian GSM, yang boleh berfungsi untuk mengawal mana-mana papan mesej di peringkat global dari lokasi yang berbeza. Sebelum maklumat yang dipaparkan, buzer dan LED akan hidup untuk memberi perhatian kepada orang ramai tentang pengumuman yang akan datang. Data yang dihantar dipaparkan di papan matriks LED. Setiap kali mereka ingin menyampaikan maklumat, mereka hanya perlu SMS kepada SIM yang berada didalam GSM Modem yang disambungkan untuk pengumuman dipaparkan dan buzer dan LED akan hidup sebelum paparan pengumuman di paparkan. Jadi, mana-mana pensyarah atau guru boleh SMS maklumat yang hendak disampaikan sebagai contoh perhimpunan yang akan diadakan di dewan seminar. Beberapa analisis telah berjaya untuk mengetahui pencapaian sistem dalam memaparkan pengumuman melalui teknologi tanpa wayar. Analisis yang telah dilakukan adalah berdasarkan kepada fungsi lokasi SMS, jumlah watak yang akan dipaparkan dan kelajuan teks penatalan. Kesimpulannya, sistem ini telah berjaya membangunkan dan dianalisis melalui fungsi yang boleh menerima SMS yang dihantar dari telefon mudah alih, memberitahu melalui menghidupkan loceng dan kemudian memaparkan di papan matriks LED.

ABSTRACT

Announcement Board is a primary thing in schools and colleges. When every announcement need to be conveyed to all, a separate person is required to take care of this notices display. In the case of digital displays if they want to change the message or style an operator have to go there. The problem of existed announcement board is that it requires manual operation and hard to handle. This project is mainly about a design and implementation of announcement board, which can send messages by using GSM. This project is based on displaying information on LED matrix board by the any part of world through GSM network, which can function to control any message board globally from different location. Before the information is displayed, the buzzer and LED will turn on to alert people’s attention about the upcoming announcement. The data are processed by microcontroller. The data that is sent are displayed on LED matrix board. As this will be the announcement board that will be used in school and colleges, so it will be easier for teachers and lecturers to convey the information. Whenever a message needs to be conveyed, they just need to SMS the message to the SIM in GSM Modem, which is connected, to the Announcement Board and the buzzer will be on before the announcement display on the board. So, this any lecturer or teacher can SMS it the message to be conveyed like urgent gathering of class students at seminar hall. Some analyses have been successfully done in order to find out the system achievement in displaying the announcement through wireless technology. The analyses that have been done are based on the location SMS function, the total character to be displayed and the speed of the scrolling text. In conclusion, the system have successfully developed and analyzed through the function that can accept the sent SMS from mobile phone, notify by switching on the buzzer and then display on the LED matrix board.

The system is basically based on a system that is used to processed the water authorized in order to manage the billing without need anyone to do it like before. It is design to receive messages from the meter to central database. The messages about the billing will be processed and then generated the monthly billing at the same time.

(24)

Then, the system function by sends another SMS as the notification to the user or owner about the amount of water billing every month. The system was the implementation that used Visual Basic and database to perform the system that works by sending the SMS notification to the user (Mohd Helmy Abd. Wahab,2007).

2.2.4 Vehicle Speed Detection by using SMS

Vehicle speed detection by using SMS is a system that control the speed by using SMS. This system was implemented to a black box for a warning system which function in controlling the speed limitation of express bus via SMS. There are three main part of the system. Firstly is the mobile phone, second is the microcontroller circuit and lastly is relay driving circuit. This system is design so that the bus driver that drove over the permitted limit can be prevented and teach the bus driver to obey the road regulation in order to prevent any accident which cause by the speed driving. These projects have been used PIC 16F873A microcontroller, mobile phone and JAI software for the programming (Elia Nadira Sabudin, 2008).

2.2.5 Power Meter Reading System using GSM Network

The Power Meter Reading System that can function automatically have used the GSM network that is basically about the automation power meter reading. It works by sending the energy consumes to e- billing system.the GSM modem will integrate the digital power meter in kWh. This system shows the function of GSM network that can send the power usage reading in messages straightly to the authorized office. The authorized office will take place by collecting and managing the received message that contains the meter reading to calculate the cost and send back the cost to the respective consumer through message (Tan, H.G.R.
