Key Technology of Unmanned Underwater Vehicle


1. Overall Technology


Underwater UAV is a highly technology-intensive and systematic project, involving dozens of professional disciplines. Each discipline restricts each other. Purely pursuing a single technical index, one will lose sight of the other. To solve these contradictions, we need to strengthen coordination in addition to a strong system concept. On the premise of meeting the overall technical requirements, the determination of individual technical indicators should take into account each other. From the point of view of hydrodynamics, in order to adapt to a wide range of navigation, the shape of underwater UAV adopts a low streamlined body. As far as possible, lightweight composite materials with light weight, high buoyancy, high strength, corrosion resistance and noise reduction are used in the structure.


2. Simulation Technology


Underwater UAV works in complex marine environment, and it is accomplished by intelligent control. Because of the inaccessibility of the working area, it is difficult to study and test the real hardware and software systems. For this reason, in the design stage of underwater UAV, simulation technology research should be carried out, which includes two parts:


3. Underwater Target Detection and Recognition Technology


At present, the underwater UAV equipment for underwater target detection and recognition is limited to synthetic aperture sonar, forward-looking sonar and three-dimensional imaging sonar.


4. Intelligent Control Technology


This technology is the key to improve the autonomy of Underwater Unmanned Aerial Vehicle (UAV) and accomplish various tasks in complex marine environment. Therefore, it is very important to study the software system, hardware system and control technology of UAV control system. Continuously improve the system structure, strengthen the ability to predict the future, so that the system has a more forward-looking and autonomous learning ability.

Whether you run a small company or a larger corporation, safety is always important, and we are not only referring here to investing in a good alarm system. Thieves can come in many forms and the technological development has allowed some of them to steal without breaking an entry. In fact, this new age robbers, commonly known as hackers do not even have to leave the comfort of their own rooms to put a huge whole in the budget of your firm. They can ship products to their door, move significant amounts of money from one account to another, or extract useful information which they can later use to cause harm to you or one of your employees. Their main goal is to break in your system and go as deep as they have to weaken the whole network and use the data they find in their own benefit. But that doesn’t mean you can’t fight back! Nowadays there is large number of IT specialists who are more than capable to provide your computers, laptops and other pieces of equipment with the vulnerability scanners, web filters and similar software that will make it strong in front of the online pirates.
