First, the frontier development and multiple capabilities of unmanned technologyAlthough 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.Summary: Unmanned technologies such as unmanned aircraft, unmanned driving, unmanned shops, unmanned hotels and unmanned banks have provided a new source of strength for coastal defense islands and border defense to defend the motherland. They have many points of convergence with the needs of coastal defense islands and border defense, and can play a great role in monitoring, dangerous task execution and logistics support. Although it is faced with challenges such as adaptability to complex environment and security and confidentiality in the application process, unmanned technology will be able to better serve coastal defense islands and frontier defense by developing protection technologies and strengthening confidentiality management, and make important contributions to defending the territorial integrity and frontier security of the motherland.

Safety and confidentiality are very important in coastal defense islands and border defense work. Unmanned technology products may face security risks such as interference and hijacking, and the data transmitted by them may also have hidden dangers of leakage. In order to solve this problem, on the one hand, we should strengthen the security protection technology of unmanned scientific and technological products, such as encrypting data transmission and setting up anti-interference mechanism; On the other hand, it is necessary to establish a strict confidentiality management system and strictly supervise the use, data storage and transmission of unmanned technology products to prevent information leakage.Unmanned technology: coastal defense, islands and frontier defense's new help to defend the motherland.Second, the meeting point between the needs of coastal defense islands and border defense and unmanned technology

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.2. Unmanned driving: an intelligent helper for land and sea transportation1. UAV: the eye of the air in coastal defense and frontier defense.
