2. Unmanned driving: an intelligent helper for land and sea transportationThird, the challenges and countermeasures of unmanned technology applied to coastal defense islands and border defense1. UAV: the eye of the air in coastal defense and frontier defense.

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.Unmanned technology: coastal defense, islands and frontier defense's new help to defend the motherland.First, the frontier development and multiple capabilities of unmanned technology

2. Unmanned driving: an intelligent helper for land and sea transportationSafety 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.1.
