Technical Field
[0001] This utility model belongs to the field of marine engineering technology and relates to a precise positioning device for ships entering and leaving dry dock based on UWB ultra-wideband technology. Background Technology
[0002] Traditional methods for ship entry and exit from dry dock rely on a large number of personnel for on-site command and real-time monitoring of the ship's status. This method is not only inefficient and susceptible to human factors, but also greatly limited by natural conditions such as wind and rain. Especially in severe weather conditions, it is difficult for personnel to effectively monitor and command, thus increasing the risks associated with ship entry and exit from dry dock.
[0003] Although some positioning systems have been applied to ship navigation management in recent years with technological advancements, these systems often only provide approximate position information and cannot achieve real-time monitoring of the ship's attitude and precise location, let alone support remote real-time video monitoring. This leaves the process of ships entering and leaving dry dock with significant safety hazards and uncertainties. Utility Model Content
[0004] To address the need for efficient, accurate, and real-time monitoring during ship docking and undocking, and to improve the safety and efficiency of these processes, this invention employs the following technical solution: a precise positioning device for ship docking and undocking based on UWB (Ultra-Wideband) technology, comprising W ship positioning signal transmitters, a data server, a 5G base station, a remote monitoring device, and...
[0005] N UWB base stations are symmetrically set up on two opposite sides of the dry dock;
[0006] M cameras are symmetrically installed on the other two opposite sides of the dry dock;
[0007] UWB base stations are installed on either side of the width of the dry dock;
[0008] One end of each of the W ship positioning signal transmitters is connected to one of the N+1 UWB base stations;
[0009] The data server is connected to N+1 UWB base stations and M cameras at the other end;
[0010] The other end of the data server is connected to one end of the 5G base station;

[0019] This invention provides a ship docking and undocking precision positioning device based on UWB ultra-wideband technology. It is a high-precision, high-efficiency, and real-time ship docking and undocking management system to solve the problems of low efficiency and susceptibility to weather caused by the reliance on a large number of personnel for on-site command and real-time monitoring of ship status in traditional methods. The system can achieve precise monitoring of ship position and attitude, and realize remote real-time video monitoring through 5G network, thereby greatly improving the safety and efficiency of ship docking and undocking.

[0023] High real-time performance: Based on 5G communication base stations, the system can realize real-time data transmission. By viewing the remote monitoring screen, management, safety and technical departments can keep abreast of the real-time situation of the ship entering and leaving the dock.
[0024] Intelligent management: Through the user interface and real-time video stream from the camera, the positional changes of the signal transmitters deployed on the ship relative to the dock UWB base station are displayed in real time, realizing intelligent management of the ship's entry and exit from the dock, improving management efficiency and safety.

[0035] M cameras are symmetrically arranged on the other two opposite sides (in the width direction) of the dry dock, with equal spacing between them;
[0036] UWB base stations are installed on either side of the width of the dry dock;
[0037] One end of the ship positioning signal transmitter 6 is connected to N+1 UWB base stations 1;

[0041] The other end of the 5G base station 4 is connected to the remote monitoring device 5.
[0042] The 5G base station 4 is located near the dock and is used to transmit data processed by the data processing center to the remote monitoring center, management computers, and mobile terminals of operators at various positions via 5G communication. Simultaneously, it can transmit instructions from the remote monitoring center and management to the mobile terminals.

[0045] M≥2.
[0046] The W≥4.
[0047] When two cameras are installed in the width direction of the dry dock, the UWB base station is placed between the two cameras.
[0048] The N+1 UWB base stations, M cameras, and 5G base stations are connected via Ethernet or Wi-Fi.
[0049] The camera used is a Hikvision DS-2DE7232IW high-definition network intelligent PTZ camera.
[0050] The data server is Dell PowerEdge R750, and the remote monitoring screen is Huawei Smart Screen V5Max.
[0051] The system uses UWB positioning technology to achieve precise location monitoring of ships entering and leaving the dock, and uses 5G communication technology to transmit real-time data to a remote monitoring terminal, enabling remote real-time monitoring of ships entering and leaving the dock.
[0052] The ship positioning signal transceiver is placed at key locations such as the bow and stern, port or starboard side of the ship to transmit UWB signals more accurately and ensure the accuracy of ship position and attitude calculations.
[0053] The Huawei Smart Screen V5Max remote monitoring screen includes a display terminal and a user interface, used to display the ship's real-time location, attitude, other relevant information within the dock, and the ship's entry and exit status. Simultaneously, by receiving real-time video streams from cameras, management, safety, and technical departments can intuitively understand the on-site situation and make corresponding decisions.
[0054] Mobile terminals: Positions such as pilot ship system operator, winch operator, and winch operator receive data, images, and instructions from superiors through the data processing center via the 5G network.
[0055] Example 1: A precise positioning and remote monitoring device for ship docking and undocking based on UWB ultra-wideband technology and 5G communication technology, specifically deployed as follows:
[0056] First, multiple UWB base stations are strategically placed around the dock to ensure that these base stations can cover the entire dock area and effectively receive positioning signals from the ships.
[0057] Ship positioning signal transmitters 6 are installed at key locations on the ship (such as the bow, stern, and center). These transceivers are connected to the ship's power system to ensure continuous operation during the ship's docking and undocking processes.
[0058] When a ship begins docking or undocking operations, its positioning transceiver 6 continuously transmits UWB signals. These signals are received by surrounding UWB base stations and immediately transmitted to a data processing server via wired or wireless means.
[0059] After receiving these signals, the data processing server 3 will use a pre-set positioning algorithm to process the signals, thereby calculating the ship's precise position and attitude in three-dimensional space.
[0060] Camera 2 collects real-time data on the status of ships entering the dock area;
[0061] Remote monitoring and command:
[0062] The data processing server 3 transmits the calculated ship position and attitude information to the remote monitoring device and mobile terminal via the 5G base station 4.
[0063] The management layer of remote monitoring device 5 can view the ship's entry and exit from the dock in real time through a large screen or mobile device, and remotely command and dispatch according to the actual situation.
[0064] Operators at each position can view information such as the ship's attitude and expected position deviation through mobile terminals, as well as instructions issued by the remote monitoring center.
[0065] Security Guarantee:
[0066] This system also has a safety warning function. When the positioning signal transmitter sends the ship's position outside the preset range or close to a dangerous area, the system will automatically trigger an alarm to remind staff to take appropriate safety measures in a timely manner.
[0067] Through the above implementation methods, the present invention achieves automatic and precise positioning and remote monitoring of ships entering and leaving the dock, greatly improving the efficiency and safety of ship management.
[0068] This device supports simultaneous monitoring and management of multiple vessels and can be expanded as needed. With continuous technological advancements, this system can be upgraded in both hardware and software to adapt to new requirements and challenges.
