[0034] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] refer to Figure 1 The present invention proposes a ship intelligent escape evacuation guidance method, comprising:

[0036] S100: Based on the acquired ship space layout data, a ship space model is created using a modeling platform, and the ship space model data is imported into a centralized controller;

[0037] S200: installing a monitoring device and a light-emitting guiding device in each room and passage of the ship, and binding the installation positions of the monitoring device and the light-emitting guiding device with the ship space model in the centralized controller;

[0038] S300: When the monitoring device detects that a disaster has occurred on the ship, an alarm signal is sent to the centralized controller;

[0039] S400: After receiving the alarm signal, the centralized controller locates the location where the disaster occurs on the ship space model, and calculates the best escape route according to the location where the disaster occurs and the escape exit;

[0040] S500: The centralized controller displays the ship space model on a preset display device, and highlights the location where the disaster occurred and the calculated optimal escape path. At the same time, the centralized controller controls the light-emitting guiding device on the optimal escape path to turn on.

[0041] It can be understood that the layout information of the internal space of the ship is first obtained from design drawings, CAD files or actual measurement data, including the structure and size data of each part such as the cabin, deck, and engine room. Then, professional 3D modeling software or platforms such as Blender, Fusion360, On Shape, etc. are used to create an accurate 3D model through the software according to the actual layout information, reflecting the structure, layout and size of each area inside the ship. Finally, the data of the created 3D ship space model is imported into the centralized controller. The centralized controller can be a computer, MCU or other devices. The centralized controller can also be connected to devices such as display screens. By importing the model data, the structure and layout of the internal space of the ship can be displayed and observed, so as to more effectively perform escape guidance operations.

[0042] Monitoring devices and light-emitting guidance devices are installed in various rooms and passages of the ship. The monitoring devices may include sensors, cameras or other types of equipment to monitor the status of the internal environment of the ship, such as temperature, humidity, gas concentration, etc. The light-emitting guidance device can be an indicator made of phosphorescent lamps or LED light strips to indicate the escape exit. The installation location information is bound to the previously created ship space model in the centralized controller so that the centralized controller can know the exact location and function of each monitoring device and light-emitting guidance device. When a monitoring device in a certain place detects a disaster such as a fire or a water leak, the monitoring device sends an alarm signal to the centralized controller to arrange escape instructions or direct staff to go to disaster relief.

[0043] After receiving the alarm signal from the monitoring device, the centralized controller quickly locates the disaster damage location on the ship space model according to the installation location information bound to the monitoring device and the ship space model. At this time, the centralized controller uses a preset mathematical algorithm to calculate the best path from the disaster damage location to the escape exit. The mathematical algorithm can be the Dijkstra algorithm, the Floyd algorithm, the D-star algorithm, etc. The calculated best path should meet the following points: the path should avoid the disaster damage area as much as possible to ensure the safety of the passengers and crew; considering the time urgency, the path should be as direct and short as possible to quickly escape from the dangerous area; the path should ensure that the escape exit is within the reachable range and the passengers can easily find and follow these exits.

[0044] The preset display device can be a fixed large screen, a small screen on a portable device, or both. The fixed large screen can be set inside the command center and other offices for overall dispatch and command, and assist in decision-making analysis, while the small screen on the portable device can be carried by the ship's staff so that they can view the location of the disaster and the best escape evacuation path as soon as the disaster occurs, thereby improving the efficiency of escape command. The above settings enable the ship's escape evacuation path to be displayed in a graphical manner, so that the staff can view the relevant situation more intuitively. Further, the display device can display the entire ship in a graphical manner and divide the ship into small display areas by area. The relevant equipment status, feedback signals and alarm points can be directly displayed on the regional graphics, supplemented by data tables, so that the relevant areas and monitoring conditions can be conveniently viewed according to different situations. When an emergency or abnormal alarm occurs, the graphics of the relevant data area automatically jump out and change color for display, alarm and assist in decision-making analysis.

[0045] Reference Figure 2 In one embodiment of the present invention, step S100 includes:

[0046] S110: Scanning the interior space of the ship to obtain three-dimensional information of the interior space of the ship;

[0047] S120: Based on the acquired three-dimensional information, a corresponding ship space model is created on the modeling platform, and reference anchor points are established in the rooms and passages of the ship space model, where the reference anchor points are used for position binding with the monitoring device and the light-emitting guiding device;

[0048] S130: Importing the ship space model data into the centralized controller.

[0049] It can be understood that firstly, scanning equipment such as cameras and sensors are used to perform environmental scanning to obtain three-dimensional information of the real space of the ship, and then this three-dimensional information is used to model the ship in a proportional manner. In addition, auxiliary modeling can be performed through design drawings, CAD drawings, and actual measurement data, so that the constructed ship space model can accurately correspond to the real space layout of the ship. Select one or more stable and representative positions in each room and channel in the ship space model to create spatial anchor points. These anchor points serve as reference points corresponding to the ship space model and the real space of the ship, ensuring that the monitoring devices and light-emitting guide devices installed on the ship later can correspond to the accurate positions on the ship space model, and preliminarily associate the ship space model with the current space. The bound ship space model is imported into the centralized control center, so that after the centralized control center receives the alarm signal of the monitoring device, it can quickly locate the location of the disaster on the ship space model according to the spatial anchor points bound to the monitoring device, so as to plan the escape evacuation path.

[0050] Reference Figure 3 In one embodiment of the present invention, in step S400, the step of calculating the best escape evacuation route according to the disaster damage location and the escape exit includes:

[0051] S410: creating an escape exit set and a distance set, wherein the escape exit set is used to store all escape exits of the ship space model, and the distance set is used to record the shortest path distance from the disaster damage location to each escape exit, and all distances are initially set to infinity;

[0052] S420: Mark the location where the disaster occurs as the current starting point, and mark any escape exit as the current escape exit;

[0053] S430: traverse all paths from the current starting point to the current escape exit, store the shortest path in a distance set, and mark the escape exit as visited;

[0054] S440: Selecting the nearest escape exit from the escape exits that have not been visited as the next current escape exit;

[0055] S450: Repeat steps S430 to S440 until all escape exits are marked as visited.

[0056] S460: Based on the shortest path distance recorded in the distance set, the shortest path from the current starting point to all escape exits can be backtracked to find.

[0057] It can be understood that the calculation steps from step S410 to step S460 are based on the Dijkstra algorithm to calculate the best path from the disaster location to the nearest escape exit. The Dijkstra algorithm is a classic algorithm for solving the single-source shortest path problem in a graph. It can be used to find the shortest path from one vertex to all other vertices.

[0058] The following are the basic concepts of Dijkstra's algorithm: Data structure, Dijkstra's algorithm uses two main data structures to implement the calculation of the shortest path (that is, two data sets), namely the vertex set (containing all the vertices in the graph) and the distance set (recording the shortest path distance from the starting point to each vertex); Initialization, first, set the distance of the starting point to 0, the distances of other vertices to infinity, and set the starting point to the current vertex; Iterative update, repeat the following steps - select the vertex with the shortest distance among the neighbors of the current vertex, set it as the next current vertex, and update the distances of other neighbors. If the distance to the neighbor through the current vertex is shorter than the currently recorded distance, update the distance; Mark vertices, after each iterative update, mark the current vertex as visited, indicating that the shortest path from the starting point to the vertex has been found; Shortest path extraction: After all vertices are marked as visited, the shortest path from the starting point to all other vertices can be extracted.

[0059] The basic idea of ​​Dijkstra's algorithm is to find the shortest path step by step by continuously updating the distance in the distance set. It ensures that each iteration will select the vertex with the shortest current distance as the next current vertex, and update the distances of other vertices through this vertex. Finally, the shortest path from the starting point to all other vertices and the corresponding distances are obtained.

[0060] In an embodiment of the present invention, after step S300, the method further includes:

[0061] S310: Connecting the centralized controller to an emergency power supply, wherein the emergency power supply is provided with an independent power supply circuit.

[0062] It can be understood that setting up a separate emergency power supply to power the centralized controller has the following advantages: high reliability and durability. In the event of a disaster, the power supply line is very likely to be damaged and cause a power outage. The emergency power supply usually uses equipment such as backup batteries or generators. These devices can provide continuous power support when the main power supply is interrupted or fails. This can ensure that the centralized controller is always available in an emergency and is not affected by power failures; continuous monitoring and warning. The centralized controller needs to operate continuously to ensure that in the event of a fire, gas leak or other emergency, it can monitor and warn the occupants and crew in real time. The separately powered emergency power supply can ensure that it can continue to work and will not fail due to main power interruption; to deal with long-term emergencies. Some emergencies may cause the main power supply to fail for a long time, such as damage to power equipment, problems with the ship's main engine or other power grid problems. The separately powered emergency power supply can provide sufficient power support to ensure that the centralized controller needs to operate for a long time until all personnel are safely evacuated or it can work normally in an emergency.

[0063] In an embodiment of the present invention, the monitoring device includes one or more of a camera, a temperature sensor, a smoke sensor, and an infrared sensor.

[0064] Understandably, cameras can be used to monitor visual information inside the ship, and can transmit images or videos in real time to help monitor the safety status of the ship and personnel activities; temperature sensors are used to measure and monitor temperature changes in various areas of the ship, which is very important for detecting fire or other heat source anomalies; smoke sensors can detect the presence of smoke and are one of the key components of the fire monitoring system; infrared sensors can detect the heat radiation of the human body or other objects and are used to monitor activities inside the ship at night or in low light conditions. By setting up the above devices, the diversity and functionality of the monitoring devices can be guaranteed to ensure comprehensive monitoring and safety of the ship's internal environment and events.

[0065] The technical solution of the present invention establishes a ship space model that can accurately correspond to the actual spatial layout of the ship. When a disaster occurs, the Dijkstra algorithm can be used to quickly calculate the optimal escape path based on the accident location and multiple escape exits, and the accident location and the calculated optimal escape evacuation path are highlighted on the ship space model, which effectively improves the escape efficiency and reduces casualties. The graphical display can help staff to provide guidance, assist in decision-making analysis, and help improve command efficiency.
