Three-dimensional space firefighting command controlling system

Abstract

The invention discloses a three-dimensional space firefighting command controlling system. The system is characterized in that a positioner and a firefighter data terminal are worn by a firefighter, a backfield data terminal and a backfield host connected with the backfield data terminal in a wireless manner are arranged at an on-site command position, the positioner calculates a positioning result of the firefighter, transmits the result to the firefighter data terminal, and sends data to the backfield data terminal through the firefighter data terminal, and the backfield host receives the data from the backfield data terminal and displays real-time position and track of the firefighter. According to the system, a holographic three-dimensional space model is constructed by employing the GIS technology, the VR technology is employed, two-group, two-dimensional and real-scene three-dimensional seamless integration in a fire scene range can be realized, the positioning of positions and movement tracks of the firefighters in the fire scene space can be realized by employing a VR+ data terminal, the entire time-space and multi-dimensional system with high space precision is constructed, and the safety of the firefighters is guaranteed in an omnibearing manner.

Description

technical field [0001] The invention relates to the field of command and control technology, in particular to a three-dimensional space fire command and control system. Background technique [0002] GIS is a geographic information system, which uses traditional cartography methods to express geographic information through abstract symbols such as various thematic maps and symbol libraries, and provides a macroscopic abstract expression method for geographic information, which greatly simplifies people's understanding of maps. However, the two-dimensional geographic information system provides users with only two-dimensional plane graphics, and there is no substantial improvement in the degree of visualization compared with traditional paper maps. With the deepening of GIS applications, This is far from satisfying people's visual needs; therefore, the conceptual model of two-dimensional visualization that simplifies the real world into a two-dimensional projection on a plane ...

Problems solved by technology

[0005] Therefore, after knowing the location of the firefighting facilities, the firefighters enter the fire scene, the determination, understanding, and understanding of the firefighting target are not comprehensive enough, and there are large errors, which will lead to untimely, insufficient and inadequate firefighting and rescue, and There is no scientific path analysis in the selection of the fire rescue path, which will lead to the fact that the rescue route may not be the best path
