In the U.S., a system of notification of imminent natural disasters Facts
University of Arkansas researchers have developed an early warning system for natural disasters, with which U.S. residents will be given full information about potentially dangerous places and required navigational assistance to those who are directly in the epicenter of events.
Network to notify the state of emergency is a self-regulating powered by solar panels system, which ensures long-term continuous operation, even if the electric power system, or wireless connection broke down. Users will get the most important information to mobile phones, personal digital assistants, tablets or laptops.
"The ultimate goal of this project is to preserve human life. Implementation of the system will not only help to prevent potential victims, but also help rescue services as soon as possible contact with the victims, which is especially important since many victims die from lack of timely assistance, "- said Nilanyan Banerjee, one of the project participants. An important prerequisite is the use of the popular devices such as smart phones, as in emergency stressful situations, people need to rely on something familiar and comfortable.
Network is a system of nodes in the geographical area. Like the server, each solar-powered site contains data that can be downloaded to the user, or if necessary, transferred from one node to another. The second aspect is important to maintain the continuity of the system, if a node fails in special weather conditions or failure typical sources of renewable energy.
The new system will warn people of impending natural disasters like tornadoes, hurricanes, earthquakes, etc. Such maps Google, users transmit information will include a map of the places most at risk, and roads within the disaster. In the example model (http://mpss.csce.uark.edu/mesh/index.html) danger zone accident highlighted in red, and green shows the safest way to the nearest first-aid station.
Before you enter a fully functioning system, researchers still need to address several problematic issues. Thus, the nodes must operate on a small amount of electricity, with enough users to send a card with the necessary information. To test it out before the end of 2012, the researchers will use a network of 40 nodes in Feyetvill, Arkansas.
Banerjee also said that this system can be used not only for emergency cases, but to travel in the wild or military operations in the deserts and other remote locations.
