A positioning system and method for emergency networking in disaster areas

Abstract

The invention relates to a disaster area emergency networking positioning system and method, and belongs to the technical field of communication positioning. The system comprises a GNSS data module which is used for obtaining coordinate data of a reference point at the periphery of a disaster area and providing the reference coordinate data for UWB emergency networking in the disaster area; The UWB emergency networking module is used for establishing UWB emergency networking in a disaster area according to the reference coordinate data; The UWB mobile tag positioning module is used for acquiring positioning data of UWB emergency networking in a disaster area; The data resolving module is used for resolving the position information of the rescuer according to the positioning data of the UWBemergency network and the reference coordinate data; And the monitoring end display module is used for receiving the position information of the rescuers and displaying the positions of the rescuersin real time. The problem that in the prior art, the quality of communication signals cannot be guaranteed on the disaster scene of building collapse, and consequently rescuers cannot be accurately positioned is solved.

Description

technical field [0001] The invention relates to the technical field of communication positioning, in particular to a UWB / GNSS-based positioning system and method for emergency networking in a building collapse transition zone at a disaster site. Background technique [0002] Earthquakes, fires, floods and other disasters are often accompanied by collapsed buildings and blocked roads. When the rescuer rescues the people in the collapsed building, it is difficult to determine the situation in the building in a short time, which delays the effective carrying out of the rescue work. At the scene of a disaster, it is difficult for the commander to rescue the trapped people within a limited time, resulting in the danger of the lives of the trapped people. The main reasons are: (1) The rescue route is not clear. The environment of the disaster scene is complex, and the visual effect is not good. It is difficult to determine the location information of the rescuers internally, whic...
