There 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.Third, the challenges and countermeasures of unmanned technology applied to coastal defense islands and border defenseAlthough unmanned shops, hotels and banks seem to belong to the service field, they play an important supporting role in coastal defense islands and border defense work. On the island, unmanned shops can provide daily necessities for the officers and men stationed in the army. Unmanned hotels can provide accommodation services for people who temporarily perform tasks, which reduces the cost of manpower management and improves the flexibility of accommodation arrangements. Unmanned banks facilitate the handling of financial services in frontier islands, such as salary distribution and fund storage, which ensures the flow of funds and financial security in frontier islands.
