Embedded multi-ship positioning information acquisition and transmission system

Abstract

The invention discloses an embedded multi-ship positioning information acquisition and transmission system, and belongs to the field of target positioning and transmission. The system comprises N data acquisition modules for acquiring position, speed, heading and attitude information of N ships, a data processing module used for receiving the position, speed, course and attitude information of the ships transmitted by the data acquisition modules and designing a communication protocol, a data transmission module used for transmitting by adopting the communication protocol designed by the data processing module and adopting a time division multiple access polling transmission mode, and a data receiving module used for receiving acceleration, angular velocity, angle, magnetic field, air pressure, height, longitude, latitude, ground velocity, satellite positioning, satellite number and horizontal and vertical position information transmitted by the data transmission module, and analyzing and displaying the ship data according to the communication protoco. The system is easy to operate, components are easy to upgrade, replace and overhaul, extra operation is not needed, automatic receiving and transmitting are achieved, many-to-one real-time information transmission is achieved, and risks are avoided.

Description

technical field [0001] The invention relates to the field of target positioning and transmission, in particular to an embedded multi-ship positioning information collection and transmission system. Background technique [0002] With the continuous development of China's economy, the scale of marine fishing continues to expand, and the marine fishing and transportation industries are becoming more and more perfect. At the same time, the increase in ship traffic has brought huge challenges to maritime management. In the management of a fleet, it is particularly important to monitor the position and speed of all ships to ensure that the ships communicate with each other, and to alarm in time to avoid collisions when the distance is less than the safe range. In addition, the large sea area and limited information exchange also lead to frequent maritime accidents, making it difficult for fleet management to detect accidents in time and implement rescue actions. Therefore, managi...

Problems solved by technology

However, due to the price, operational complexity, and lack of understanding of AIS equipment, most small fishing boats in China have not installed it yet.

[0008] AIS and VDES can meet the information communication between ships and ships and shores, but cannot complete the information interaction between multiple ships and mobile fishery surveillance ships
