First, the frontier development and multiple capabilities of unmanned technology3. Unmanned shops, hotels and banks: the service guarantee of frontier islands.1. Adaptability challenges in complex environments

The coastal defense island area is facing the problems of marine climate, strong wind, high humidity and salt spray corrosion, and the border defense area has complex terrain and extreme climatic conditions. These environmental factors put forward high requirements for unmanned scientific and technological products. For example, when an unmanned aerial vehicle flies over the ocean, salt fog may erode its electronic equipment, and unmanned vehicles may have problems such as difficulty in starting the engine in the alpine mountain area on the border. In view of these problems, it is necessary to develop protective technologies that adapt to special environments. For example, special moisture-proof and anti-corrosion treatment is carried out for the electronic equipment of drones, and engines and parts adapted to the cold environment are developed for unmanned vehicles.Unmanned technology: coastal defense, islands and frontier defense's new help to defend the motherland.Third, the challenges and countermeasures of unmanned technology applied to coastal defense islands and border 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.Unmanned science and technology: a new boost to coastal defense islands and border defense.Although 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.
