| Ringkasan: | Copper cable is used as a medium of communication whether for a fixed telephone line
or internet services. Currently, the price of the copper increases due to a high demand of
global trading market. As consequences, telephone cable stealing activities in Malaysia
are also increased due to the copper inside the telephone cable. Therefore, this project
presents the works in designing and developing an innovative apparatus that will be able
to help the local telecommunication company to monitor and detect not only the area or
location of loss signal occur but also the distance of the telephone cable being cut. This
project applies the FPGA-based monitoring system using GSM (Global System for
Mobile) network. The project used 555 timer as a capacitance detector to detect the
frequency value of the copper cable. The Altera DE2-70 board is used to calculate the
cable distance, which influenced by the cable frequency. After detecting an occurrence
of a cable has been cut, this prototype will automatically activate alarm and send an
instant message (SMS) to alert the person in charge indicating the area and the distance
of the cable being cut. |
