在地震、海嘯、山洪等自然災害發生的時候,地面基站常常會被毀壞,災害地區的通信基礎設施損壞不能提供通信服務,這使得救援行動的開展受到較大的阻礙。無人機基站不受災害地區基礎通信設施的限制可快速為災害地區提供大范圍的可靠通信。無人機基站不受災害地區基礎通信設施的限制,可以以主從無人機方式快速為災害地區提供大范圍的可靠通信,其中主無人機是固定的空中基站可以為應急通信控制中心提供可靠通信覆蓋。

簡介:在地震、海嘯、山洪等自然災害發生的時候,地面基站常常會被毀壞,災害地區的通信基礎設施損壞不能提供通信服務,這使得救援行動的開展受到較大的阻礙。無人機基站不受災害地區基礎通信設施的限制可快速為災害地區提供大范圍的可靠通信。


Introduction: When natural disasters such as earthquakes, tsunamis, and flash floods occur, ground base stations are often destroyed, and the 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.

無人機基站不受災害地區基礎通信設施的限制,可以以主從無人機方式快速為災害地區提供大范圍的可靠通信,其中主無人機是固定的空中基站可以為應急通信控制中心提供可靠通信覆蓋。


以主無人機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。無人機可以分為固定翼和旋轉翼無人機,固定翼無人機能夠保持在空中的持續飛行,旋轉翼無人機可以在空中懸停。


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.



無人機中繼通信中,任務無人機和中繼無人機之間的信道以及中繼無人機和地面控制終端間的信道存在差異。


無人機之前的數據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送給無人機;下行鏈路為遙測鏈路,即將無人機上的遙測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.



無人機作為移動中繼可以根據任務部署,成本效益高,移動性好,并且比起傳統的固定中繼具有靈活的 3D 位置,飛行軌跡等更多的可優化維度,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.

用戶應根據自身實際情況出發,選購一款或多款產品搭配使用。多旋翼臨時基站、多旋翼長時間滯留基站、固定翼空中基站等。


選擇保障當下應急救援通信,還是恢復周邊范圍內民用通訊,得視情況而定。當然,如果設備資源充足條件下,可同時進行,從而全方位實施通信救援。


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 implement communication rescue.
