UH1 SHOFAR: Mass Notification System for Local Disasters


The Philippines is a natural hazard place. The government has initiated several efforts such as establishing a disaster risk reduction management council (DRRMC) who is responsible for ensuring protection of the people during disasters or emergencies. Other initiatives were provided like hydrometeorological stations and mobile alerts to increase the prevention, preparedness and mitigation measures with a goal to have a safer, adaptive and disaster Filipino communities towards sustainable development.

Despite these, the country still lacks of preventive technical DRRM mechanisms like a warning and evacuation alert system. A local disaster risk reduction management office is seen not prepared when local disaster strikes. Several study and known disaster frameworks suggest the use of early warning system to reduce the possibility of harm or loss. Thus, this project.

The mass notification system is an ICT-enabled early warning system that will provide the local disaster risk reduction management office with capacity to respond quickly and seamlessly to disaster events. It is an integrated system composed of an alarm system, public address system, surveillance system and bulk SMS system. It provides quick remote alarm and announcement, real time and clear surveillance, and widest dissemination of disaster-related information.

The system has utilized the system life cycle process as its method. The process includes requirement analysis, design, development and testing. Initially, the area of interest was surveyed to determine the hazard vulnerabilities: flooding and landslide. The requirements were specified and the wireless link viability was verified. During the design, the area was in need of a multi-hop link between the operation center and the affected area. The major components of the system were central station and a plurality of substation where each substation is operably connected to said central station. During the testing, the central station was able to issue alarm notification to the plurality of substation simultaneously during disaster. Each substation has activated an alarm sound at a certain time duration. It has further produced a flashing of lights continuously and broadcast messaging alerts via bulk SMS. However, the central station upon deactivation has initiated public address for general announcement and paging. It has facilitated surveillance that sourced from the camera, and terminal equipment like sensor nodes.

The system was envisioned to increase the capacity of the DRRM offices in preparing, mitigating and responding to disaster events.
