First, the frontier development and multiple capabilities of unmanned technologyChina has a long coastline, numerous islands and vast land borders, and it is difficult for traditional monitoring methods to cover these vast areas. Unmanned technology can solve this problem well. Drones and unmanned devices can extend the monitoring range and fill the dead ends of monitoring. No matter in the waters around distant islands or in the inaccessible border mountainous areas, unmanned technology can continuously monitor and ensure that China's coastal defense islands and border defense areas are always under monitoring.1. Monitoring requirements in a wide area

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.2.
