Real-time remote monitoring system for TV3 FLY FM and HOT FM radio station (TV3-RMS)

Abstract

A radio, combination of a transmitter and a receiver works by transmitting the radio waves along with the message (voice data or data for radio modem) that have been encoded onto a sine wave. The receiver will then decodes the sine waves and retrieves the message in their original format. Both the transmitter and the receiver use antennas to radiate and capture the radio signals. For radio broadcasting purpose, a radio station usually has a transmitter and an antenna located at the station, while the receivers are usually located at various locations that could be 100 km away from the station. However, a single transmitter is not able to cover a wide area; instead a radio transmission tower is needed that is located at high area such as a mountain peak to transmit the radio signals for larger areas. A technical personnel is needed to monitor and to control this tower station. However, such manual maintenance activities can only be done if the transmission tower is located at local areas. To overcome this situation, a system called Remote Monitoring System has been developed to aid users (in this case, operator) in supervising the transmitter on remote location and on unmanned site. The purpose of this system is to monitor the transmitter’s condition and reporting the current status of the transmitter back to the operator at the station. The data of the transmitter are collected by using an electronic device called Remote Terminal/Telemetry Unit (RTU) and is placed on the transmission tower. The RTU communicates with the monitoring system through the GSM network provided by local telecommunication company.
