Description

System searching based on drone for rescuing mountaineers}

The present invention relates to a search technology using a distress rescue drone, and more particularly, to a search system using a drone for an unmanned aerial vehicle for rescue of a mountain distress to accurately determine the position of the distress.

In Korea, where 64% of the country's land is forest, there are dangers of life and isolation due to forest disasters such as forest fires and landslides as well as mountaineer distress. Recently, as well as mountaineering, casualties in the mountains are increasing due to the increase of the mountain leisure population, and the forms of accidents are also diversified. Looking at the data of mountain accidents by 17 metropolitan cities published by the government, the rate of missing and falling accidents is the highest among mountain accident reports, and the second highest incidence of distress accidents. Is increasing.

In the case of distress accidents occurring in mountainous areas, emergency relief is often delayed due to the long travel time for location and rescue activities of the distress, so it is necessary to develop the technology necessary for rapid location and shortening of relief time for distress people. It is increasing. Mountain lifesaving technology, which quickly locates and shortens relief time for victims, has recently been attempted using unmanned aerial vehicles at home and abroad, and it is possible to reduce the casualties due to mountain accidents and disasters by extending the golden time for the rescue. As expected, technology development is active.

However, there is a limit to quickly grasp the situation of the distress and increase the accuracy of location for rescue in case of a landslide caused by earthquake and typhoon and forest disaster such as large forest fire or carelessness of hikers.

The problem to be solved by the present invention is to provide a search system using an unmanned aerial drone for a mountain distress rescue to efficiently perform distress rescue and disaster control by combining ICT positioning technology and thermal imaging camera.

Search system using an unmanned aerial vehicle drone for mountain distress rescue according to an embodiment of the present invention for solving the above problems is equipped with a wireless sensor-based life detection ICT integrated module in the distress scene, the mobile phone of the distress people in the air Drone for scanning Wi-Fi signals; A ground control device for controlling the drone to fly to a desired position; And based on the signal scanned in the drone for the drone, the distress structure structure integrated server for collecting the location information, signal strength, time, barometric pressure data of each mobile phone of the distress through the LTE communication network in real time .

The distress rescue structure server, when the information for the detection of people and rescue the rescuer is transmitted through the LTE communication network, via the agent program and the DB server to determine the location of the mobile phone of the distress through the Google Open API interworking function from the web server It is done.

The unmanned aerial drone is equipped with a general-purpose camera and a thermal infrared recognition module, characterized in that for transmitting image information.

According to the present invention, the GPS and the mobile phone's Wi-Fi function can be used to automatically detect and recognize the user's Wifi signal, and combine thermal imaging technology to locate the exact location of the distress. By making it possible to monitor at the control center at all times even in night, fog, and rain, which are difficult to visually identify, it is possible to quickly identify the position of the distress in the web viewer system so that the rescue of the distress can be made quickly.
