Earthquake early warning and protection system

Abstract

The invention discloses an earthquake disaster early warning and protection system. The system comprises a distributed earth crust vibration monitoring sensor subsystem, a distributed data link radiostation transmission subsystem, a household early warning terminal subsystem and a safety protection subsystem. According to the characteristics that the transmission speed of the system utilizing seismic waves is low and the electromagnetic wave transmission speed is high, earthquake information is early warned to people additionally provided with the system in advance; a reliable earthquake disaster avoiding space is provided for people additionally provided with the system, the space not only can protect people inside a house from being hurt when the house collapses, but also can provide necessary survival conditions for people, people deeply buried underground can safely survive for one month, and enough rescue time is provided for rescuers. The system is suitable for residents near aseismic zone, is particularly suitable for large cities with high population density and people living in tall buildings, can effectively protect high-grade earthquakes when the high-grade earthquakescome, and ensures that people additionally provided with the system are not threatened by life safety.

Description

technical field [0001] The invention relates to the field of smart home and natural disaster protection, specifically a semi-enclosed system made of high-strength steel, which uses the difference between seismic wave transmission speed and electromagnetic wave transmission speed to warn people who have installed the protection system in advance. Protective devices are used to provide protection for the crowd, prevent high-level earthquakes from causing house collapse and causing damage to the crowd, and improve the necessary living conditions for the personnel in the device so that they can safely wait for rescue in the device. Background technique [0002] Online information shows that Japanese scientists have launched the world's first emergency earthquake warning system, which began trial operation in 2004 and was officially put into use in 2007. After the system detects signs of an earthquake, it immediately notifies residents and major institutions, allowing residents to...

Problems solved by technology

[0003] To sum up, at present, the country and even the whole world have not taken effective protective measures in the face of earthquake disasters. Although earthquake early warning systems have been developed in China and Japan recently, they only play an early warning role and can give the masses The time for the people to provide escape is only about 10 seconds. During these 10 seconds, people with good physical fitness and responsiveness can escape from the room to the public refuge area, while other elderly people and children can only look for them nearby.
