Wi-Fi-based post-earthquake pressed and buried personnel positioning method

Abstract

The invention belongs to the technical field of space positioning, and provides a Wi-Fi-based post-earthquake pressed and buried personnel positioning method related to data mining. According to the Wi-Fi-based post-earthquake pressed and buried personnel positioning method related on data mining, based on the Wi-Fi probe technology, a Wi-Fi signal of Wi-Fi equipment of a pressed and buried personnel reaching a weighted center of a signal corresponding to each sensor at a minimum signal loss on a surface of a piercing position of a pressed and buried object (an optimal signal piercing point) is used as a plane position of the pressed and buried person, the accurate positioning of the Wi-Fi equipment of the pressed and buried personnel is realized combining with a theory of Apollonius (Apollonian circle), and the problem of non-sight distance and multi-path propagation of the signal causes by being pressed and buried is better solved. The positioning of the post-earthquake pressed and buried personnel is realized, and the survival of the pressed and buried personnel can be more likely.

Description

technical field [0001] The invention belongs to the technical field of space positioning, and relates to a Wi-Fi-based post-earthquake buried personnel positioning method related to data mining. Background technique [0002] Every year in the world, there are many accidents of crushing people caused by natural disasters such as earthquakes and landslides. The loss of life caused by them is immeasurable, and the proportion of deaths due to failure to be rescued in time is relatively large. [0003] Nowadays, the search methods for trapped persons are mainly by means of point-by-point detection equipment such as "life detector", "thermal infrared life detector", "sonic vibration life detector". However, this kind of equipment is very difficult when facing large-scale disasters such as earthquakes, the search speed is slow, the environment is greatly affected, and it consumes a lot of manpower and material resources. At present, there is no technical means that can automatical...
