A search and rescue system for missing persons in mountainous areas based on UAV and Beidou positioning

Abstract

The invention discloses a search and rescue system for missing persons in mountainous areas based on unmanned aerial vehicles and Beidou positioning, which relates to the technical field of tourism safety and includes a missing persons rescue terminal and a search and rescue communication integration system. The missing persons rescue terminal includes a positioning module and a sign monitoring module , a control module and a signal transmitting module; the output terminal of the physical sign monitoring module is bidirectionally connected to the control module, and the output terminal of the control module is connected to the transmitting module; the physical sign monitoring module includes a temperature sensor and a pulse sensor, The temperature sensor and the pulse sensor are respectively connected with the control module; the present invention has the advantage that the missing person can be searched for in an optimal way when the missing person cannot autonomously send a distress message.

Description

technical field [0001] The invention relates to the technical field of tourism safety, in particular to a search and rescue system for missing persons in mountainous areas based on drone crews and Beidou positioning. Background technique [0002] Mountainous scenic spots are frequent areas of tourism safety accidents. Due to the complex characteristics of mountainous scenic spots such as high and rugged terrain, sparse population, changeable weather, traffic congestion, and poor accessibility for sightseeing, tourists are prone to fall or fall off cliffs, get lost, disappear or lose contact, and other tourism safety accidents. In the past 10 years, there have been frequent incidents of disappearance or casualties of tourists in mountainous scenic spots across the country due to fare evasion or intentional exploration by tourists. Complex mountainous scenic spots often have a vast area, and security monitoring and field emergency measures cannot achieve full coverage and rea...

Problems solved by technology

[0003] Existing technical solutions use drones and navigation and positioning systems to search and rescue missing persons by using the signals sent by positioning mobile terminals held by missing persons. However, in complex mountain environments, missing persons may encounter various accidents. In the state of abnormal signs, it is difficult to activate the positioning mobile terminal autonomously, and cannot send distress information to the search equipment, so that when the drone team passes by the area where the missing person is located, it cannot detect the missing person, and even after multiple monitoring, it may be It is determined that there are no missing persons in this area, and the detection is continued in other areas, so that the missing persons completely miss the chance of being rescued
