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.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.

Security and confidentiality issues

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.Unmanned science and technology: a new boost to coastal defense islands and border defense.Unmanned science and technology: a new boost to coastal defense islands and border defense.

1. Monitoring requirements in a wide areaChina 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.
