Problems solved by technology

UUV, glider and other positioned nodes (anchor nodes) are commonly used to transmit location information to other unlocated nodes. The unlocated nodes calculate the node position and range according to the information arrival time and Bayesian criterion, and compare their coordinates with the detected The data is sent to the base station or central server together; the disadvantage is that GPS cannot be used directly; the channel bandwidth is narrow, and protocols with high communication overhead cannot be used; nodes move with the water flow; this brings great difficulties to underwater node positioning, and surface buoys Compared with the base station on the ship, the target is large, and the construction cost is also high

Abstract

The invention discloses an underwater positioning system of a floating base station. The underwater positioning system comprises the floating base station and an underwater positioning device, whereina sound source generator on a buoy acquires the position information monitored by a GPS positioning device and sends an encodable sound wave signal, a hydrophone of the underwater positioning deviceis arranged on the outer surface of an underwater device to detect the sound wave signal, and a second processor determines the distance between the sound source generator and the hydrophone accordingto the sound wave signal received by the hydrophone, and then determines the underwater position of the underwater device. According to the invention, the buoy of an erected deep sea floating draughtfan can be used to position a base station and the underwater positioning device through underwater sound wave distance measurement; the floating draught fan is larger in size, so that the accurate GPS positioning can be obtained, and the positioning precision of the underwater positioning device can be improved; not only is the required power supply problem solved, but also the base station construction cost of the underwater positioning device is reduced, and the concealment is improved.

Description

Technical field [0001] The invention relates to the technical field of underwater positioning, in particular, an underwater positioning system of a floating base station. Background technique [0002] Underwater positioning is a very important marine basic technology, which has a wide range of applications in marine scientific research, marine resource development, marine environmental protection, marine safety, etc.; using underwater positioning technology, people can master the lander, The precise location of underwater vehicles such as submersibles; due to the strong absorption of radio waves by the water medium, underwater positioning technology using sound waves as information carriers has become the main choice; but in deep oceans, sound waves are also susceptible to various impurities in the sea The speed of sound wave propagation in seawater is also affected by various hydrological conditions, which leads to the difference in the speed of sound waves under water, which ma...
