Automatic novel system for sending emergency alert and alarm for multi events through radio broadcasting transmission system in Perú

Abstract

This paper describes an integrated system of emergency alert and alarm [1], which uses robust radio diffusion technologies recommended by ITU [2] [3] (DTT-Digital Terrestrial Television and Radio FM). For the insertion of the emergency information in the radio frequency, generators were developed for radio FM and television using RDS (Radio Data System) and information tables respectively. A receiver module developed by INICTEL-UNI (National institute of research and training of telecommunications) decodes the emergency signal and activates sound sirens to alert target audience. This emergency signal is based on the CAP protocol [4] (Common Alerting Protocol) and PLANAGERD [5] (Plan Nacional de Gestión del Riego de Desastres), which allows defining multiple emergency events for dissemination. Finally the management of the system is carried out through a web interface, which is responsible for the emergency activation of multiple events and control and monitoring of the receiver module parameters.
