1. Monitoring requirements in a wide areaThe 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.

3. Unmanned shops, hotels and banks: the service guarantee of frontier islands.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.1.
