Deploying method after earthquake for sensor network node based on information physical system

Abstract

The invention discloses a deploying method after earthquake for a sensor network node based on an information physical system. A distributed multimedia sensor network is combined with an information physical system and is deployed for rescue after earthquake. According to the deploying method disclosed by the invention, on the basis of a CPS (Cyber Physical Systems) technology and a DMSN (Distributed Multimedia Sensor Network) technology, an after-earthquake rescue node deployment strategy is designed by mainly adopting an RFID (Radio Frequency Identification Device) technology and an FSO (Free-Space Optical) technology; the use conditions of resources such as distributed sensor nodes and an intelligent label are counted and collected through a central information system; then the rescue activity is designed and deployed according to the targeted scheme, so that the quickness and accuracy of rescue are ensured at highest quality and the life safety of rescue persons is ensured at full blast; and the scheme obtains benefits in the after-earthquake analysis.

Description

technical field [0001] The present invention is a scheme based on distributed multimedia sensor network (Distributed Multimedia Sensor Network) and information physical system (Cyber ​​Physical Systems). It is of great significance to ensure the safety of people's lives and property. This project belongs to the field of CPS and Internet of Things technology. Background technique [0002] Natural disasters are a huge threat to the development of human civilization. Several major earthquakes in recent years, such as the Wenchuan earthquake in May 2008 (magnitude 8), the 2011 Concepcion earthquake in Chile (magnitude 6.8), the 2011 Qinghai Yushu earthquake (magnitude 7.1), the 2011 Earthquakes (magnitude 9) have caused huge disasters to the safety of human life and property. The post-disaster rescue work is an important project to deal with natural disasters, and the most prominent challenge is the timeliness and breadth of disaster relief. However, due to many reasons such...

AI Technical Summary

Problems solved by technology

[0005] (3) Due to the wide area of ​​the earthquake and the depth of the search and rescue, the pressure to rescue the buried and trapped people within the golden 72 hours of rescue is relatively high

In many cases, although blanket search and rescue is adopted, the lack of purpose results in a waste of time

[0006] (4) A major earthquake will cause the magnetic poles of the earth to deflect, which will cause great damage to communication facilities. Most of the conventional communications will not be able to operate normally at the first time, which may cause the aircraft to be unable to fly and the victims to be unable to contact the outside world.

[0007] (5) During the rescue process, since the victims may be trapped in the collapsed buildings, the handling of reinforced concrete works is time-consuming and laborious, the workload is heavy, and it will bring safety risks to the trapped people. How to perceive the trapped people at any time? Vital signs of trapped people are a test

[0009] (7) Based on the nuclear earthquake caused by the Japanese earthquake, human beings will face the threat of radiation on the issue of nuclear rescue. Therefore, the data collection in the earthquake area, such as the aerosol in the air, gas iodine samples, wet fallout and other samples during nuclear radiation Continuous acquisition, measurement, and analysis are required, and it is extremely dangerous for humans to enter the radiation area for measurement
