3. Unmanned shops, hotels and banks: the service guarantee of frontier islands.Unmanned technology: coastal defense, islands and frontier defense's new help to defend the motherland.China has a long coastline, numerous islands and vast land borders, and it is difficult for traditional monitoring methods to cover these vast areas. Unmanned technology can solve this problem well. Drones and unmanned devices can extend the monitoring range and fill the dead ends of monitoring. No matter in the waters around distant islands or in the inaccessible border mountainous areas, unmanned technology can continuously monitor and ensure that China's coastal defense islands and border defense areas are always under monitoring.

Third, the challenges and countermeasures of unmanned technology applied to coastal defense islands and border defenseSecond, the meeting point between the needs of coastal defense islands and border defense and unmanned technologyThere are many dangerous environments and tasks in coastal defense islands and border defense work. For example, maritime patrols in bad sea conditions, patrols in disputed border areas, etc. The application of unmanned technology can make people avoid directly facing these dangers. Unmanned aerial vehicles can patrol the sea area in front of storm warning, and unmanned vehicles can patrol the border minefield, which greatly reduces the risk of casualties and ensures the task.
