1. UAV: the eye of the air in coastal defense and frontier defense.The logistics support of coastal defense islands and border defense areas is facing problems such as long distance and difficult transportation. The services provided by unmanned technology such as unmanned shops, hotels and banks are helpful to improve the efficiency of logistics support. Through the automatic replenishment system of unmanned shops, the island garrison can obtain the needed materials in time; The fast check-in and check-out system of unmanned hotels facilitates the accommodation arrangements of people passing by; The self-service of unmanned banks ensures the safe and convenient use of funds and provides a solid logistical foundation for security work.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.

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.UAV plays an important role in coastal defense islands and border defense. In coastal defense, UAV can cruise over the vast sea area of China for a long time, and use its advanced optical and radar equipment to monitor the activities of ships at sea. For example, it can timely find those ships that illegally intrude into China's waters, whether they are small fishing boats or large cargo ships. According to military experts, the cruising efficiency of drones is several times that of traditional patrol ships. In border areas, drones can cross rugged mountains and deserts to monitor the border. Its high-resolution camera can clearly identify abnormal activities such as people and vehicles on the border, which greatly improves the scope and accuracy of border monitoring.Second, the meeting point between the needs of coastal defense islands and border defense and unmanned technology

2. Task execution in dangerous environmentThere 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.First, the frontier development and multiple capabilities of unmanned technology
