簡(jiǎn)介：在地震、海嘯、洪水等自然災(zāi)害發(fā)生的時(shí)候，地面基站常常會(huì)被毀壞，災(zāi)害地區(qū)的通信基礎(chǔ)設(shè)施損壞不能提供通信服務(wù)，這使得救援行動(dòng)的開展受到較大的阻礙。無人機(jī)基站不受災(zāi)害地區(qū)基礎(chǔ)通信設(shè)施的限制可快速為災(zāi)害地區(qū)提供大范圍的可靠通信。
Introduction: During natural disasters such as earthquakes, tsunamis, and flash floods, ground base stations are often destroyed, and communication infrastructure in disaster areas is damaged and unable to provide communication services, which greatly hinders the implementation of rescue operations. Unmanned aerial vehicle base stations are not limited by the basic communication facilities in disaster areas and can quickly provide reliable communication on a large scale for disaster areas.

無人機(jī)基站不受災(zāi)害地區(qū)基礎(chǔ)通信設(shè)施的限制，可以以主從無人機(jī)方式快速為災(zāi)害地區(qū)提供大范圍的可靠通信，其中主無人機(jī)是固定的空中基站可以為應(yīng)急通信控制中心提供可靠通信覆蓋。
以主無人機(jī)為中心用圓形軌跡飛行的空中基站，為邊緣用戶提供通信覆蓋。無人機(jī)可以分為固定翼和旋轉(zhuǎn)翼無人機(jī)，固定翼無人機(jī)能夠保持在空中的持續(xù)飛行，旋轉(zhuǎn)翼無人機(jī)可以在空中懸停。
The drone base station is not limited by the basic communication facilities in disaster areas, and can quickly provide reliable communication over a large range in the form of master-slave drones. The master-slave drone is a fixed aerial base station that can provide reliable communication coverage for the emergency communication control center.
An aerial base station flying in a circular trajectory centered around the main drone, providing communication coverage for edge users. Drones can be divided into fixed wing and rotary wing drones. Fixed wing drones can maintain continuous flight in the air, while rotary wing drones can hover in the air.
無人機(jī)中繼通信中，任務(wù)無人機(jī)和中繼無人機(jī)之間的信道以及中繼無人機(jī)和地面控制終端間的信道存在差異。
無人機(jī)之前的數(shù)據(jù)鏈路分為上行鏈路和下行鏈路。上行鏈路為遙控鏈路，即將地面控制終端的指令信息發(fā)送給無人機(jī)；下行鏈路為遙測(cè)鏈路，即將無人機(jī)上的遙測(cè)信息傳遞給地面控制站。
In drone relay communication, there are differences in the channels between task drones and relay drones, as well as between relay drones and ground control terminals.
The data link before the drone was divided into uplink and downlink. The uplink is a remote control link, which sends command information from the ground control terminal to the drone; The downlink is a telemetry link, which transmits telemetry information from the drone to the ground control station.
無人機(jī)作為移動(dòng)中繼可以根據(jù)任務(wù)部署，成本效益高，移動(dòng)性好，并且比起傳統(tǒng)的固定中繼具有靈活的 3D 位置，飛行軌跡等更多的可優(yōu)化維度，可以提高通信性能。
As a mobile relay, drones can be deployed according to tasks, with high cost-effectiveness, good mobility, and more optimized dimensions such as flexible 3D positions and flight trajectories compared to traditional fixed relays, which can improve communication performance.
受連日暴雨影響，京津冀多個(gè)地區(qū)遭遇山洪，高速主通道堵塞，陷入停水停電、通信隔絕的困境。聯(lián)合飛機(jī)集團(tuán)深入貫徹總書記關(guān)于防汛救災(zāi)工作重要指示精神，繼保障北京市門頭溝區(qū)應(yīng)急物資投送后，8月1日連夜組建了另一支TD220無人直升機(jī)救援隊(duì)伍，奔赴河北省張家口市涿鹿縣執(zhí)行保障應(yīng)急通訊任務(wù)！
Affected by rainstorm for several days, several regions in Beijing, Tianjin and Hebei were hit by mountain torrents, and the main high-speed channel was blocked, which led to water and power outages and communication isolation.

Users should choose one or more products to use in combination based on their actual situation. Temporary multi rotor base stations, multi rotor long-term stranded base stations, fixed wing aerial base stations, etc. The choice between ensuring current emergency rescue communication or restoring civilian communication within the surrounding area depends on the situation. Of course, if the equipment resources are sufficient, it can be carried out simultaneously to comprehensively implement communication rescue.
