Description

Technical Field

[0001] The utility model relates to the technical field of ship escape, in particular to an intelligent ship escape evacuation system. Background Art

[0002] Ships are large water transportation vehicles with large volume, complex structure, multiple decks and large number of passengers. Once a fire or other disaster occurs, it is very easy to cause a major accident. When an accident occurs, the existing escape guidance method is mainly to set up emergency lights and luminous signs on the preset escape path, and the staff will evacuate the crowd.

[0003] At present, domestic passenger ships are mainly marked with intermittent self-luminous phosphorescent stickers. Such signs cannot quickly indicate passengers to safe exits in dim light and smoky conditions, which is not conducive to the safe evacuation and escape of passengers. At the same time, a lot of experience has shown that traditional emergency lights become completely ineffective in smoky harsh environments, because in the event of a fire, smoke tends to rise to the ceiling, covering the overhead lighting within a few seconds, and soon it is not enough to guide people to the exit safely. In such harsh environments, escaping passengers or crew members must stay as close to the ground as possible to greatly improve visibility, and it is also conducive to reducing the inhalation of toxic smoke. When there are more passengers on the ship or the internal structure is more complex, for the preset escape path, there may be a high flow of people on the escape path and a relatively crowded situation, which may even cause a stampede accident in severe cases. Utility Model Content

[0004] The main purpose of the utility model is to provide a ship intelligent escape evacuation system, which aims to guide escapees more efficiently and intelligently, can maintain a good guidance effect in a smoky environment, and can also reduce the possibility of crowded trampling incidents, with high safety.

[0005] In order to achieve the above-mentioned purpose, the utility model proposes a ship intelligent escape and evacuation system, comprising:

[0006] A main control module, wherein the main control module at least comprises a computing unit;

[0007] An early warning device, which is arranged in each room and passage on the ship, and is electrically connected to the main control module, and is used to send a first alarm signal to the computing unit when a disaster occurs;

[0008] A crowd monitoring device, which is arranged in each channel on the ship and is electrically connected to the main control module, and is used to send a second alarm signal to the calculation unit when the crowd flow in the channel exceeds a preset threshold;

[0009] A low - level guiding unit, where the low - level guiding unit at least includes guiding light strips arranged along the wall of the ship passage and adjacent to the ground, and the guiding light strips are electrically connected to the main control module;

[0010] Wherein, when the calculation unit receives the first alarm signal, it calculates the optimal escape route and controls the guiding light strips on the optimal escape route to light up. When the calculation unit receives the second alarm signal, it recalculates the sub - optimal escape route starting from the position where the second alarm signal is sent, and controls the guiding light strips on the sub - optimal escape route to light up.

[0011] In an embodiment of the present utility model, the low - level guiding unit further includes luminous identification signs, and the luminous identification signs are arranged at intervals on the wall of the ship passage and are electrically connected to the guiding light strips.

[0012] In an embodiment of the present utility model, the distance between the guiding light strips and the luminous identification signs from the ground is less than 30 cm.

[0013] In an embodiment of the present utility model, the early warning device includes a camera, a temperature sensor, and a smoke sensor.

[0014] In an embodiment of the present utility model, the main control module further includes a display, and the display is electrically connected to the camera.

[0015] In an embodiment of the present utility model, the ship intelligent escape and evacuation system further includes an emergency power supply module, the emergency power supply module is electrically connected to the main control module, and when the calculation unit receives the first alarm signal, it controls the emergency power supply module to turn on.

[0016] The technical solution of the present utility model is to set a main control module, an early warning device, a pedestrian flow monitoring device, and a low - level guiding unit that are electrically connected in sequence. The low - level guiding unit is arranged adjacent to the ground and is more easily discovered and recognized by escapees. Especially in the case of low visibility or smoke - filled environment, when escapees are squatting or crawling forward on the ground, they can easily observe the low - level guiding unit. When the early warning device detects a disaster, it sends a first alarm signal to the calculation unit; when the pedestrian flow monitoring device monitors that the pedestrian flow in the passage exceeds the preset threshold, it sends a second alarm signal to the calculation unit. When the calculation unit receives the first alarm signal, it calculates the optimal escape route and controls the guiding light strips on the optimal escape route to light up. When the calculation unit receives the second alarm signal, it recalculates the sub - optimal escape route starting from the position where the second alarm signal is sent, and controls the guiding light strips on the sub - optimal escape route to light up, which can effectively relieve the congestion of people, further improve the escape efficiency, and also reduce the possibility of safety accidents.

[0021] The realization of the purpose, functional features and advantages of the present invention will be further described with reference to the embodiments and the drawings. Specific embodiments

[0022] In order to make the purpose, technical solutions and advantages of this application clearer, the following will further elaborate on this application in combination with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

[0023] Referring to Figure 1 , the present invention proposes a ship intelligent escape and evacuation system, including a main control module 1, an early warning device 2, a pedestrian flow monitoring device 3 and a low-position guiding unit 4. The main control module 1 at least includes a calculation unit 11; the early warning device 2 is arranged in each room and passage on the ship, and the early warning device 2 is electrically connected to the main control module 1, and is used to send a first alarm signal to the calculation unit 11 when a disaster damage occurs; the pedestrian flow monitoring device 3 is arranged in each passage on the ship and is electrically connected to the main control module 1, and is used to send a second alarm signal to the calculation unit 11 when the pedestrian flow in the passage exceeds a preset threshold; the low-position guiding unit 4 at least includes a guiding light strip 41 arranged along the wall of the ship passage and adjacent to the ground, and the guiding light strip 41 is electrically connected to the main control module 1; wherein, when the calculation unit 11 receives the first alarm signal, it calculates the optimal escape route and controls the guiding light strip 41 on the optimal escape route to light up. When the calculation unit 11 receives the second alarm signal, it recalculates the sub-optimal escape route starting from the position where the second alarm signal is sent, and controls the guiding light strip 41 on the sub-optimal escape route to light up.

[0024] Understandably, the computing unit 11 can be a device such as a computer or an MCU, which is used to control the entire intelligent ship evacuation system. The warning device 2 can include various sensors, cameras 21 or other types of devices, which are used to monitor the state of the ship's internal environment, such as temperature, humidity, gas concentration, etc., to ensure the diversity and functionality of the warning device 2, so as to ensure the comprehensive monitoring and safety of the ship's internal environment and events. When the warning device 2 detects a disaster, it sends a first alarm signal to the computing unit 11. The computing unit 11 calculates the optimal escape route according to mathematical calculation methods, such as Dijkstra algorithm, Floyd algorithm, D-star algorithm, etc., and controls the guiding light strip 41 on the optimal escape route to light up, so that the escape personnel can escape along the guiding light strip 41.

[0025] When there are a large number of passengers on board or the internal structure is relatively complex, it is possible that the flow of people on the escape route is relatively high and crowded, and in severe cases, even stampede accidents may occur. The flow monitoring device 3 is used to monitor the real-time flow of people in the passage. The flow monitoring device 3 can be a camera 21 with a microprocessor, an infrared sensor or other devices, which calculates the current flow of people according to the real-time flow data in the passage by a mathematical formula. When the flow of people exceeds the preset threshold, it sends a second alarm signal to the computing unit 11, indicating that the passage is congested. The computing unit 11 recalculates the sub-optimal escape route starting from the position where the second alarm signal is sent, and controls the guiding light strip 41 on the sub-optimal escape route to light up, which can effectively relieve the congestion of people, further improve the escape efficiency, and also reduce the possibility of safety accidents.

[0026] Past experience has shown that traditional ceiling emergency lights become completely ineffective in a harsh environment filled with smoke. Because in the event of a fire, the smoke often rises to the ceiling, covering the overhead lighting within seconds and quickly becoming insufficient to guide people safely to the exit. In such a harsh environment, the escaping passengers or crew members should stay as close to the ground as possible to greatly improve visibility and also help reduce the inhalation of toxic smoke. The guiding light strip 41 is set adjacent to the ground, making them easier to be discovered and recognized by the escapees, especially in low visibility or smoke-filled situations. When the escape personnel are squatting or crawling forward on the ground, they can easily observe the guiding light strip 41 and the luminous sign 42; it also reduces the impact of smoke. During a fire, the smoke often rises upward, and the lower position of the guiding light strip 41 can reduce the impact of smoke on the lighting, ensuring that the light can still effectively illuminate the escape route; furthermore, the guiding light strip 41 is an LED light strip, using LED lamp beads that emit light purely from the chip (pure green or yellow-green light), and this color of light has stronger penetration in a smoke-filled environment and better guiding effect.

[0027] Refer toFigure 1 , in an embodiment of the present application, the low-level guiding unit 4 further includes a luminous sign 42, which is spaced on the wall of the ship passage and electrically connected to the guiding light strip 41.

[0028] It can be understood that only setting the guiding light strip 41 may make it difficult to clearly indicate the escape direction, resulting in incorrect judgment of the escape direction by the escape personnel. Therefore, a luminous sign 42 is set on the wall of the ship passage at intervals to indicate the escape direction, so that the escape personnel can quickly escape along the correct direction of the escape path under the joint guidance of the guiding light strip 41 and the luminous sign 42, improving the escape speed and efficiency.

[0029] Furthermore, luminous signs 42 should be set at the turning points and bifurcations of the passages inside the ship. When the calculation unit 11 recalculates the escape path after receiving the second alarm signal, the luminous signs 42 at the turning points and bifurcations can quickly guide the escape personnel to switch paths, further improving the escape efficiency.

[0030] Refer to Figure 1 , in an embodiment of the present application, the distance between the guiding light strip 41 and the luminous sign 42 from the ground is less than 30 cm.

[0031] It can be understood that a height below 30 cm means that the positions of the guiding light strip 41 and the luminous sign 42 are closer to the ground, making them easier to be discovered and recognized by the escapees. Especially in the case of low visibility or smoke filling, when the escape personnel are squatting or crawling forward on the ground, a height below 30 cm from the ground is undoubtedly a relatively easy observation height, and the escape personnel can naturally observe the guiding light strip 41 and the luminous sign 42 in the squatting or crawling state.

[0032] Refer to Figure 1 , in an embodiment of the present application, the warning device 2 includes a camera 21, a temperature sensor 22, and a smoke sensor 23.

[0033] It can be understood that the camera 21 can be used to monitor the visual information inside the ship, and can transmit images or videos in real time to help monitor the safety status of the ship and the activities of personnel; the temperature sensor 22 is used to measure and monitor the temperature changes in various areas inside the ship, which is very important for detecting fires or other abnormal heat sources; the smoke sensor 23 can detect the presence of smoke and is one of the key components of the fire monitoring system. By setting the above devices, the diversity and functionality of the monitoring devices can be ensured to ensure the comprehensive monitoring and safety of the internal environment and events of the ship.

[0034] Refer to Figure 1, in an embodiment of the present application, the main control module 1 further includes a display 12, and the display 12 is electrically connected to the camera 21.

[0035] Understandably, the display 12 is electrically connected to the camera 21 and can play the images transmitted by the camera 21 in real time, enabling the staff to more intuitively view relevant situations such as the disaster damage occurrence scene and the passenger evacuation situation, so as to conduct overall dispatching and command and assist in decision-making analysis. Further, the display device can display the entire ship in a graphical manner and divide the ship into small display areas by region. The relevant device status, feedback signals, and alarm points can be directly displayed on the regional graph, supplemented by a data table, so that the relevant regions and monitoring situations can be conveniently viewed according to different situations. When an emergency or abnormal alarm occurs, the graph of the relevant data region automatically pops up and changes color for display, alarm, and decision-making analysis assistance.

[0036] Refer to Figure 1 , in an embodiment of the present application, the ship intelligent escape system further includes an emergency power supply module 5, and the emergency power supply module 5 is electrically connected to the main control module 1. When the calculation unit 11 receives the first alarm signal, it controls the emergency power supply module 5 to turn on.

[0037] Understandably, setting the emergency power supply module 5 to supply power to the main control module 1 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 module 5 usually uses devices such as backup batteries or generators, which can provide continuous power support when the main power supply is interrupted or fails, so as to ensure that the main control module 1 is always available in an emergency and is not affected by power failures; continuous monitoring and warning. The main control module 1 needs to run continuously to ensure that in the event of a fire, gas leakage, or other emergencies, it can monitor and warn the passengers 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 the interruption of the main power supply; coping 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 module 5 can provide sufficient power support to ensure that the main control module 1 can operate for a long time until all personnel are safely evacuated or can work normally in an emergency.

[0038] The technical solution of the utility model is to set a main control module 1, a warning device 2, a pedestrian flow monitoring device 3 and a low-position guiding unit 4 which are electrically connected in sequence. The low-position guiding unit 4 is arranged adjacent to the ground and is more easily discovered and recognized by the escapees. Especially in the case of low visibility or smoke filling, when the escapees are squatting or crawling forward on the ground, they can easily observe the low-position guiding unit 4; when the warning device 2 detects a disaster damage, it sends a first alarm signal to the calculation unit 11; when the pedestrian flow monitoring device 3 monitors that the pedestrian flow in the passage exceeds the preset threshold, it sends a second alarm signal to the calculation unit 11. When the calculation unit 11 receives the first alarm signal, it calculates the optimal escape route and controls the guiding light strip 41 on the optimal escape route to light up. When the calculation unit 11 receives the second alarm signal, it recalculates the sub-optimal escape route starting from the position where the second alarm signal is sent and controls the guiding light strip 41 on the sub-optimal escape route to light up, which can effectively relieve the congestion of people, further improve the escape efficiency, and also reduce the possibility of safety accidents.
