Description

technical field [0001] The invention relates to a data projection system similar to an aircraft black box, in particular to a data box, its data box and an emergency data projection system. Background technique [0002] Ships have become well-developed and commonly used transportation, production, and operation equipment for fertilization. They are widely used in major rivers, lakes, and oceans, and they have really brought a lot of convenience to people's lives. [0003] Shipwrecks are the most frequent accident of ships. Although the existing technology and emergency rescue can make the shipwreck accidents near waters and seas better handled, and the safety of personnel can also be better guaranteed. [0004] But in distant waters and distant sea areas, where there are few people, once a shipwreck occurs, it will lead to disastrous consequences. Moreover, because the current positioning and communication technology has not yet achieved global and regional coverage, if an ...

Problems solved by technology

[0006] However, at present, ships are only equipped with emergency rescue devices such as lifeboats, and there is no emergency data recording device like the black box of an airplane. This makes it possible to never find the location of the accident if there are no survivors after the accident.

And once the accident comes too fast, people have no time to escape in lifeboats
