Second, the meeting point between the needs of coastal defense islands and border defense and unmanned technology1. UAV: the eye of the air in coastal defense and frontier defense.3. Unmanned shops, hotels and banks: the service guarantee of frontier islands.

Third, the challenges and countermeasures of unmanned technology applied to coastal defense islands and border defense2. Security and confidentiality issuesThere 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.

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.First, the frontier development and multiple capabilities of unmanned technology3. Unmanned shops, hotels and banks: the service guarantee of frontier islands.
