The invention belongs to the technical field of fire rescue, and discloses a fire trapped person positioning method and
system.The fire trapped person positioning method comprises the following steps that a
heart rate sensor, a body temperature sensor and a
respiratory rate sensor are integrated into a portable device, vital sign data are collected, and the vital sign data are sent to the portable device; the data are sent to the
central processing unit through a
wireless transmission mechanism for monitoring and analysis, and
vital sign monitoring data are obtained; by integrating sensor data and performing real-time analysis, more accurate vital sign
state recognition and abnormal early warning are realized, by combining real-time acquisition of acoustic fluctuation and
acoustic wave feature
processing, the trapped person positioning precision is further improved, and by calculating sound source positioning coordinates and optimizing rescue
resource distribution, the positioning accuracy of the trapped person is improved. Moreover, an efficient and targeted rescue strategy and priority allocation can be formulated, the rescue efficiency is remarkably improved, the search time and resource waste are reduced, and the
survival probability of trapped persons is improved.
