Japan applies RFID radio frequency identification technology to prevent earthquakes

Since the 5.12 earthquake in China, earthquake resistance and post-disaster reconstruction have become hot words in various industries, and the security industry has paid great attention. Throughout the world, Japan’s technology (including RFID radio frequency identification technology) used in a series of measures such as earthquake resistance and earthquake disaster relief is worth studying.
In Japan, natural disasters such as earthquakes are also extremely common, and the country has established a relatively complete earthquake disaster relief system. At the same time, information technology and RFID radio frequency identification technology are also widely used in all aspects of earthquake prevention.
The Japan Meteorological Agency uses network technology to achieve “rapid forecasting of emergency earthquakes” to reduce damage. That is, the home and office appliances, doors, etc. are connected to the Internet, which is automatically controlled by the computer. When the seismometer captures the longitudinal wave of the source, an emergency forecast can be issued after 3-5 seconds, and the system receives an emergency earthquake forecast quickly. After that, the fire source can be automatically cut off immediately. Generally speaking, it takes about 30 seconds for the seismic shear waves to arrive at places from tens of kilometers to hundreds of kilometers away from the epicenter.
Mobile phones sold in Japan since last year have been fitted with GPS receivers at the behest of disaster response agencies. This way, rescuers can track the user’s location even if the caller doesn’t know where they are. Currently, about 30% of mobile phones used in Japan can be tracked by GPS.
Radio frequency identification technology (RFID) can also play a role in disaster relief. For example, if an RFID tag is attached to the road surface of the refuge, the refugee can clearly know the specific location of the safe refuge through the portable device; another example, if someone is buried in the rubble and cannot move or call for help, the mobile phone with the built-in RFID tag It will tell the search and rescue personnel the specific location of the buried person, so that the search and rescue personnel can carry out the rescue as quickly as possible.
