[0083] The working principle of this utility model's ground-air coordinated casualty sensing and evacuation unmanned system is as follows:

[0084] 1. After receiving the search and rescue mission information, the ground station uses the communication module to send instructions to the integrated control module of the wounded person perception and positioning UAV, start the UAV's flight attitude, and fly to the search area along the preset trajectory;

[0085] 2. The life detection radar collects biometric data of the target area in real time and sends the data to the ground station via the communication module. After a suspected target is detected, the ground station sends an instruction to the integrated control module of the wounded person perception and positioning UAV via the communication module, and the UAV approaches to search.

[0086] 3. The optoelectronic pod acquires high-resolution images in real time and transmits them to the streaming media server via the RTMP streaming media protocol using a communication module. The streaming media server then analyzes the image data to identify the characteristics of the wounded.

[0087] 4. The streaming media server fuses image recognition and radar positioning data to generate comprehensive casualty location data.

[0088] 5. The ground station processes the information perceived by the wounded, generates the preceding task, establishes a global coordinate system to realize the preceding path planning, and sends it to the control module of the wounded evacuation unmanned vehicle through the communication module of the ground station.

[0089] 6. During the operation of the unmanned vehicle for casualty evacuation, it can avoid obstacles and adjust its path in real time based on environmental perception and navigation positioning, and transmit video images and status information back to the ground station in a synchronized manner;

[0090] 7. Upon reaching the location of the injured person, the robotic arm lifting mechanism is activated, the stretcher support is deployed, and teammates near the injured person are waiting to assist in the boarding process.

[0091] 8. After the wounded are placed in the evacuation vehicle, the ground station's unmanned transport platform generates a evacuation mission, establishes a global coordinate system to plan the evacuation route, and transports the wounded to the designated location for treatment.

[0092] As can be seen, in response to the practical needs of field-based wounded patient evacuation, this utility model designs and realizes a ground-air coordinated unmanned wounded patient evacuation system. It employs a drone / unmanned vehicle collaborative operation, integrating intelligent components such as drones, unmanned vehicles, life detection radar, optoelectronic pods, and robotic arm lifting mechanisms, enabling manned / unmanned collaborative operation for wounded patient evacuation. This increases the wounded patient detection radius, reduces operational workload, and improves the efficiency of wounded patient treatment.

Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.
