      • Remote Control Management for Large Scale FM Transmitter Sites

        S. S. Yang,Haider A. F. Mohamed,M. Moghavvemi,S. Bala Murali 제어로봇시스템학회 2008 제어로봇시스템학회 국제학술대회 논문집 Vol.2008 No.10

        This paper proposes a PLC and SCADA based system for remote control management of Large Scale FM Transmitter Sites. FM Broadcasting began in Malaysia in the 70’. It provided improvements over AM broadcasting producing higher quality service to the listener. As the number of FM services has increased rapidly, the number of transmitter sites also increased. The need for monitoring the performance of transmitter site equipment such as electrical systems, generators, air conditioning system, fire system, transmitters, and communication systems is becoming critical as these sites are becoming larger and more sophisticated. The proposed system can be used to monitor, manage, control and measure transmitter site parameters and performance from a networked computer or a dial up computer. Status and alarms can be monitored in real time with theassistance of custom designed SCADA system. If faults are detected at transmitter sites, the PLC formulates and sends the corresponding alarm codes to a centralized control centre. The system was set up and tested through rigorous simulations of the transmitter site failures and evaluated for seven months. The proposed system has been installed and continuously operated on live FM transmission system.
