Radio frequency identification technology plays a huge role in post-earthquake rescue

　　Nowadays in the era of the Internet of Things, the momentary connection and dynamic perception of people and things, things and things, as well as intelligent decision-making and ubiquitous applications, have moved the focus of urban disaster reduction and relief services forward, gradually shifting from post-disaster relief to prevention-oriented Perceived early warning. It can be said that this is a revolutionary change, greatly reducing the occurrence of disasters, and gradually shifting from passive emergency response to active early warning and disaster prevention. The application of radio frequency identification technology in disaster relief brings great convenience to disaster relief.

　　With the deterioration of the natural environment, natural disasters have frequently appeared in recent years. As an emerging technology, the Internet of Things technology will be more applied to disaster prevention and rescue in the face of disasters. Radio frequency technology and wireless transmission Sense, GPS global positioning, barcode technology, etc. all play their respective roles in the face of various natural disasters, providing a good technical guarantee for the safety of people’s lives and properties.

　　Time is the disaster of life. The Internet of Things technology has won more emergency and rescue time for emergencies in various situations. What are the specific functions of the Internet of Things technology in disasters? What role can it play in the protection of people's lives and property? Let's talk about the application of Internet of Things technology in earthquake disasters.

　　Geological disasters, Internet of Things technology applied to prevention and rescue

　　In the early years, British researchers had begun to study the use of RFID and sensors to monitor houses in earthquakes. They called the prototype built in Greece "self-healing" houses. This kind of house is specially designed with gap space in the wall, and the material that can become fluid under strong pressure is added to the wall.

　　If the pressure is caused by the earthquake, the fluid will flow back into the gap without affecting the solid wall. As a result, the house still exists, but may move its location. If the building does not collapse, the data collected through RFID and sensors will be used to determine the position offset. In addition, the RFID tags and sensors in the building can jointly construct an alarm system to warn of the upcoming earthquake.

　　The post-disaster rescue work RFID also showed its magical powers. In Japan, RFID tags are affixed to the evacuation road pavement so that asylum seekers can clearly know the specific location of the safe evacuation site through portable devices, which plays a very good guiding role. If someone is buried in the rubble, the trapped person can provide the search and rescue personnel with their own specific location information through the mobile phone with built-in RFID tag, so that the search and rescue personnel can start the rescue as quickly as possible.

　　Disaster evacuated personnel can mark their identity information by wearing RFID wristbands, which can avoid frequent recording of evacuees' information. When emergencies occur, the medical team can quickly track the evacuated people based on the RFID wristbands. Provide medical rescue for special groups of people (the disabled, patients, etc.). By reading the RFID wristband, the paramedics can extract the relevant information of the rescued person in the system for timely and effective rescue.
