Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] refer to figure 1 Schematic diagram of the application scene of the model in the present invention. When a SDN-based spiral mobility model constructed by the present invention is applied to a fire scene, the search and rescue control center cooperates with the on-site command vehicle at the application layer to command the rescue team to enter the disaster area. The various rescue teams in the disaster area are scattered throughout the disaster area to obtain the on-site emergency situation; the control layer collects and processes the information of the on-site emergency situation; the data layer generates the spiral trajectory data of the UAV according to the information provided by the control layer, such as Figure 4 , Figure 5 As shown; the search and rescue UAV searches according to this trajectory, so as to achieve acc...

Abstract

The invention provides a spiral line mobility model construction method based on an SDN, which is used for solving the problems of unsmooth track and inaccurate coverage of an existing model in searchand rescue scenes. According to the scheme, the method comprises the following steps: 1) constructing an application layer including a search and rescue control center and a field command vehicle forcommanding a search and rescue team to enter a disaster area; 2) constructing a control layer to collect emergency events occurring in a scene, calibrating priorities of the emergency events, sortingthe emergency events, and generating a target area search list according to an event sequence; 3) generating unmanned aerial vehicle moving track data according to the region search list provided bythe control layer, and establishing a data layer; 4) enabling the application layer, the control layer and the data layer to jointly form an SDN-based spiral line mobility model, and employing the model to complete the coverage of the disaster area. According to the invention, the smoothness of the flight path is ensured, and the accurate search of the target area is realized; the system can be used for searching and rescuing victims in disaster scenes and providing temporary aerial base stations for the victims.

Description

technical field [0001] The invention belongs to the field of mobility control, and relates to an air mobility model, specifically a method for constructing a helical mobility model based on a software-defined network (SDN) (Software Defined Network), which can be used for searching and retrieving victims in disaster scenarios. Rescue, and provide temporary aerial base stations to victims in the area. Background technique [0002] The main task of the air mobility model is to accurately simulate the mobility characteristics of air nodes and control the real-time position of air nodes. The evaluation of the air mobility model is mainly based on two points, one is the smoothness of the generated trajectory, and the other is the ability to accurately cover the target area. The smoothness of generated trajectories is mainly affected by aerodynamic and mechanical constraints, and the ability to cover the target area mainly depends on the real-time positions of nodes in the air. ...
