Embodiment Construction

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0056] It should be noted that the mobile terminal in the present invention is carried by personnel working on the water (such as the crew), so the term "alarming / rescuing the mobile terminal that fell into the water" in the present invention essentially means "rescuing the drowning personnel carrying the mobile terminal". Call the police / rescue".

[0057] The invention provides a water falling alarm system combining open and closed loop modes, such as figure...

Abstract

The invention provides a sinking alarm system and method combining an open loop mode with a closed loop mode, and belongs to the technical field of water search and rescue. The system comprises an onboard base station and at least one mobile terminal. The onboard base station comprises a closed loop broadcaster, a driven alarm processing device, a driving alarm processing device, a base station positioning device, a base station alarm device, a shipwreck detection device and an open loop broadcaster. Each mobile terminal comprises a closed loop response device, a water-sensitive sensor, a driving alarm device, a terminal positioning device and an open loop response device. An alarm mode that the open loop mode and the closed loop mode are combined is provided, the mobile terminals falling in water are positioned, it is guaranteed that sailors can give an alarm in time when falling into water and can be rescued in time, and therefore rescue efficiency is improved, and rescue resources are saved.

Description

technical field [0001] The invention relates to the technical field of water search and rescue, in particular to a water falling alarm system and method combining open and closed loop modes. Background technique [0002] There are a large number of crew members working on large ships and the scope of work is widely distributed. The sea environment is very complex and changeable, and accidents of crew members falling into the water often occur. However, due to the difficulty of alarming and positioning after the crew fell into the water, the difficulty of rescue was increased, thereby affecting the efficiency of rescue. The existing modes of the distress alert system are divided into two types: closed loop and open loop. In the closed-loop mode, the alarm and search and rescue are limited only between the terminal and the corresponding shipboard base station. In this mode, only the base station corresponding to the terminal organizes the search and rescue, which can quickly...
