Description

Technical Field

[0001] The utility model belongs to the technical field of underwater detection, and in particular relates to a multi-channel communication integrated terminal and an underwater vehicle. Background Art

[0002] With the development of science and technology, robots have more and more application scenarios, and underwater vehicles have also become a demand. Underwater vehicles can be used for underwater observation, underwater search, remote control reconnaissance and other tasks.

[0003] During operation, traditional underwater vehicles generally choose to use optical fiber or cable to achieve real-time communication between the underwater vehicle and the control platform according to mission requirements. However, cables are heavy and costly, and cannot meet the needs of long-distance navigation. Moreover, due to the characteristics of its material, optical fiber is easily broken by external forces, which can cause the underwater vehicle to lose control.

[0004] Based on this, underwater vehicles based on wireless communication came into being. However, due to the constraints of underwater vehicle size, volume, weight and other parameters, the wireless communication system of underwater vehicles must have the characteristics of small size and light weight, which also leads to the inability of existing wireless communication systems for underwater vehicles to have more communication capabilities. They can only have basic limited communication means such as digital transmission modules and WeChat communication modules, and do not have other communication means such as Wi-Fi modules and wireless remote control modules. In addition, the existing wireless communication systems for underwater vehicles mostly use independent component communication methods, that is, each communication component uses an independent communication interface, resulting in numerous communication interfaces and diverse protocols, which makes control more difficult.
