Description

Technical Field

[0001] This utility model relates to the field of marine engineering technology, specifically to a ground-based positioning system for marine engineering. Background Technology

[0002] Human beings have an increasing demand for marine engineering activities and a growing understanding of the complexity of the marine environment. As humans further develop and utilize marine resources, such as seabed oil and gas exploration, submarine pipeline laying, and offshore wind farm construction, the need for location information in marine engineering has become increasingly important and precise.

[0003] In the field of marine engineering, the accuracy and reliability of ground-based positioning systems are crucial to the success of projects. Traditional ground-based positioning systems mainly rely on a single positioning technology, such as the Global Positioning System (GPS). However, in complex and ever-changing marine environments, such as the deep sea, islands, or near coastlines, GPS signals may be interfered with or have poor coverage, leading to a decrease in positioning accuracy or even the inability to locate. In addition, a single positioning technology is difficult to adapt to the changing marine environment and cannot meet the demand for precise location information.

[0004] Therefore, based on the above-mentioned search and combined with existing technologies, a ground-based positioning system for marine engineering is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a ground-based positioning system for marine engineering to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0011] Preferably, the rotating component includes: a mounting column, which is fixedly mounted on the top surface of the base, a mounting groove is formed on the top surface of the mounting column, a turntable is rotatably connected to the inner wall of the mounting groove, the top surface of the turntable is fixedly connected to the bottom surface of the laser rangefinder, and a motor is fixedly installed inside the mounting groove.

[0012] Preferably, the output shaft of the motor is connected to the bottom surface of the turntable, and the turntable rotates synchronously when the motor output shaft rotates.

[0013] Preferably, a rope is fixedly installed on the top surface of the base.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. By incorporating positioning components and integrating multiple positioning technologies such as GPS receiver, inertial navigation system, geographic information system, sonar equipment, and laser rangefinder, high-precision multi-source positioning is achieved. In complex and ever-changing marine environments, the GPS receiver can acquire preliminary position information, while the inertial navigation system calculates the current position and velocity by measuring the acceleration and angular velocity of the carrier, which is particularly suitable for areas where GPS signals are interfered with or difficult to cover. At the same time, the geographic information system and sonar equipment provide map information and underwater positioning data respectively, further enhancing the accuracy and reliability of positioning. The introduction of the laser rangefinder provides high-precision position reference, and its omnidirectional measurement capability enables the system to cover a wider area and acquire richer position information. This multi-source information fusion positioning technology significantly improves the positioning accuracy and adaptability of the system, providing more reliable and efficient position information services for marine engineering.

[0016] 2. By incorporating control components, precise control and efficient management of the system are achieved. The data processing unit within the control components is responsible for receiving, processing, and analyzing data from various sensors. Through multi-source information fusion technology, high-precision positioning calculations are realized. A high-precision clock module ensures data synchronization and accuracy, while the power management module is responsible for the system's power supply and management, ensuring stable operation. The communication module enables communication between the system and other devices or platforms, transmitting positioning data and control commands. This allows the system to seamlessly interface and collaborate with other systems or devices. This intelligent control and data processing technology not only improves the system's automation level and operational efficiency but also reduces the need for manual intervention and the possibility of human error, providing strong technical support for the smooth progress of marine engineering.

[0029] Working principle:

[0030] In use, the base 1 serves as the supporting foundation for the entire system, connected to the connecting plate 2 via four support rods 3 to form a stable structure. The GPS receiver 4 mounted on the connecting plate 2 receives signals from satellites to obtain preliminary location information. Then, the positioning components begin to play their crucial role. The inertial navigation system 8 is rotatably connected to the inner wall of the protective box 6, calculating the current position and velocity by measuring the carrier's acceleration and angular velocity. This technology is particularly suitable for areas where GPS signals are difficult to cover or interfere with. Simultaneously, the geographic information system 9 provides maps and topographic information of the marine environment, offering important auxiliary information for positioning. A sonar device 10 is fixedly installed on the bottom of the base 1. This device uses sound waves for underwater positioning, particularly suitable for waters where GPS signals are difficult to penetrate. The sonar device 10 can accurately measure underwater depth, distance, and other information, further improving positioning accuracy. To provide even higher precision position references, the system is also equipped with a laser rangefinder 11. The laser rangefinder 11 measures distance using a laser beam. Driven by a motor 23, it achieves omnidirectional measurement via a rotating component consisting of a mounting column 20 and a turntable 22. This design allows the laser rangefinder 11 to cover a wider area and acquire richer positional information. The gyroscope 12 and accelerometer 13, as auxiliary devices to the inertial navigation system 8, measure the angular velocity and acceleration of the carrier, respectively, working together with the inertial navigation system 8 to calculate the carrier's attitude. The combination of these data allows the system to more accurately determine the carrier's motion state and direction. The control components are responsible for the system's data processing and communication functions. The data processing unit 16 receives data from various sensors and achieves high-precision positioning calculations through multi-source information fusion technology. The high-precision clock module 17 ensures data synchronization and accuracy.
