Description

Disaster relief field communication system and working method

Technical Field

The application relates to the technical field of disaster relief communication, in particular to a disaster relief field communication system and a working method.

Background

In disaster relief sites, communication interruption is easy to occur, and the disaster relief work is greatly unchanged. At present, an unmanned aerial vehicle can be adopted to form a communication link above a disaster relief site so as to ensure smooth communication between search and rescue personnel and a command center.

However, after the communication problem is solved, whether rescue is timely or not is also a problem, and for disaster sites in small areas, rescue workers can concentrate on searching and rescuing wounded persons in the small areas and can intensively place and treat wounded persons. However, in the case of disaster sites in large areas, such as earthquake sites, flood sites, mountain fire sites, etc., the conditions of large areas, wide wounded distribution, long search and rescue time, etc., are involved, and at this time, it is difficult for rescue workers to search and rescue wounded in each area at the same time. After rescuing the wounded, the rescue personnel should deal with the method is as follows: the wounded person is conveyed outwards, and then the wounded person is returned to search and rescue other wounded persons, so that the delay time is long, and the subsequent timely search and rescue of other wounded persons is not facilitated. The other method is as follows: part of rescue workers can be left on site to rescue wounded, and the rest of rescue workers continue to carry out search and rescue work, but the occupied manpower is more, and the follow-up timely rescue of wounded is also not facilitated. The final method is as follows: the wounded person who the rescue personnel will be ordinary and lightly wounded is left in place to contact command center arranges personnel in order to carry wounded person outside, then the rescue personnel keeps on going, carries out search and rescue work.

Obviously, the final method is relatively suitable for large-area search and rescue sites. This approach then still has drawbacks: after the rescue workers contact the command center, the rescue workers cannot send the accurate positions of the wounded persons to the command center, and the rescue workers can only locate the area where the wounded persons are located approximately through the GPS function of the unmanned aerial vehicle. For mountain sites, the topography is complex, and even if a rough area is located, it is difficult for externally augmented personnel to reach the wounded location at the first time, which often delays the treatment of the wounded.

In addition, the search and rescue personnel are in the area with complex topography, and the phenomenon of getting lost possibly occurs, so that the rescue personnel can also be in dangerous situations. Especially after the communication network is interrupted due to accidents, the command center is difficult to contact with the rescue workers at the first time, and the positions of the rescue workers are obtained. In this case, personal safety of the rescuer cannot be ensured.

In view of the above problems, no effective solution has been proposed at present.
