Problems solved by technology

However, due to the limitation of the coverage of mobile communication base stations, mobile signals cannot cover the sea area more than 50 kilometers away from our coast. It mainly relies on the manual method of eye positioning of search and rescue personnel onboard search and rescue aircraft / ships, as well as route prediction and personnel drift. Traditional technical means such as predictive models have low timeliness and accuracy, and cannot meet the needs of locating people in distress in the first place and quickly rescue them

Embodiment Construction

[0020] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.

[0021] The embodiment of the present invention provides a method for locating a target at sea, which is mainly applied to a help terminal installed on the target body, such as figure 1 As shown, the main processing steps include:

[0022] Step S11: The rescue terminal installed on the target obtains the position information of the target through the Beidou satellite positioning system;

[0023] Step S12: The rescue terminal sends the location information to the search and rescue terminal, so that the search and rescue terminal analyzes the location information, obtains the sea location of the target object, and displays the sea location on the electronic chart.

[0024] The maritime target positioning method of the embodiment of the present invention relies on the Beidou satellite positioning system, there is no c...

Abstract

The invention relates to the technical field of satellite communication, in particular to a marine target positioning method, a help seeking terminal and a search and rescue terminal and system. The method includes: the help seeking terminal disposed on a target acquires the location information of the target through a Beidou satellite positioning system; the help seeking terminal transmits the location information to the search and rescue terminal to allow the search and rescue terminal to analyze the location information so as to the location of the marine target and display the location on an electronic sea map. By the marine target positioning method, the help seeking terminal and the search and rescue terminal and system, information basis is provided for fast search and rescue, defects of rescuing systems such as mobile wireless positioning systems for people falling into offshore water in the prior art are overcome, positioning accuracy of the targets falling into water is increased, limitation by offshore distance is avoided, reliable basis is provided for search and rescue of the targets falling into water, rescuing time can be effectively shortened, and rescuing efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a method for locating a maritime target, a terminal for calling for help, a terminal for searching and rescue and a system. Background technique [0002] In recent years, my country's maritime emergency search and rescue capabilities have been significantly improved, and maritime search and rescue work has also made remarkable achievements. Offshore search and rescue mainly uses the existing mobile communication network to analyze and solve the wireless positioning signal of the person in distress through mobile communication, determine the position of the person in distress at sea, clarify the base point and scope of search and rescue at sea, and realize the relationship between the person who fell into the water and the floating equipment at sea ( such as search and rescue of small fishing boats). However, due to the limitation of the coverage of mobile communi...
