China 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.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.Third, the challenges and countermeasures of unmanned technology applied to coastal defense islands and border defense

There 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.1. Adaptability challenges in complex environments2. Security and confidentiality issues

Unmanned science and technology: a new boost to coastal defense islands and border defense.1. UAV: the eye of the air in coastal defense and frontier defense.2. Task execution in dangerous environment
