Description

Technical Field

[0001] This application relates to the field of ammonia-fueled ship technology, and in particular to a warning system for ammonia gas leak hazard areas. Background Technology

[0002] Ammonia, as a toxic gas, poses significant safety and health risks in marine applications. A leak can severely threaten the health of crew members, including burns to the skin, eyes, and respiratory tract, as well as potential lung swelling and death. Effective response to ammonia leaks requires establishing and improving emergency response mechanisms, including timely detection of leaks, rapid isolation of contaminated areas, provision of personal protective equipment, and development of emergency evacuation plans. However, in practice, ammonia leaks still pose a risk of harm to crew members.

[0003] Currently, ammonia leak detection systems are generally installed in key areas and near key equipment, or combined with predictive models to forecast the diffusion of ammonia in the atmosphere. The prediction period is typically within 30 minutes of an incident to ensure timely emergency response. However, predicting ammonia diffusion requires considering parameters such as leakage rate and evaporation rate. These parameters are crucial for accurately predicting the diffusion range but can also affect the speed of emergency response. Failure to implement a reasonable emergency response or escape strategy within 30 minutes of an incident could lead to serious consequences. Furthermore, the lowest ammonia concentration that humans can detect is 1.5 ppm, although ammonia can be detected by smell. However, long-term exposure can lead to olfactory fatigue, making it difficult for individuals to detect higher concentrations of ammonia, potentially affecting emergency response measures and increasing the risk of complications.

[0004] Currently, in the design and application of ammonia-fueled ships, existing monitoring systems are insufficient in terms of coverage and response speed. Furthermore, there are no warning systems installed in crew passageways, preventing crew members from directly observing the spread of ammonia in outdoor passageways and equipment areas. Therefore, to improve ship safety and ensure crew safety, further research and development of ammonia leak warning mechanisms are needed to enable crew members to quickly take necessary emergency measures. Summary of the Invention

[0005] In view of this, this application proposes an ammonia gas leak hazard warning system, which can effectively protect the life safety and health of crew members on ammonia-fueled ships and has high practicality and reliability.

[0006] To achieve the above objectives, this application provides an ammonia gas leak hazard warning system, including several ammonia gas detection devices arranged in multiple areas of the ship, control equipment arranged in the control room, and a terminal computer;

[0007] The ammonia detection device includes a gas concentration detection module, a main board module, and an indicator light module connected in sequence. The gas concentration detection module is used to detect the ammonia concentration in the air. The main board module is used to control the conduction of the internal logic circuit according to different ammonia concentrations and to control the indicator light module to display different levels of alarm lights.

[0008] The control device is connected to the plurality of ammonia detection devices, and is configured with power supply and signal transmission for each ammonia detection device.

[0009] The terminal computer is connected to the control device and is used to configure and monitor the system, and to provide corresponding emergency response plans based on the alarm level of the ammonia detection device.

[0010] Therefore, the ammonia gas leak hazard warning system provided in this application, by deploying ammonia detection equipment in multiple areas of the ship and configuring it uniformly, detects the ammonia concentration in the air in real time, and controls the conduction of internal logic circuits according to different ammonia concentrations to realize the judgment of alarm level and control the indicator light module to display alarm lights of different levels, providing intuitive warning information to the crew. When the system detects an ammonia leak and triggers an alarm, the terminal computer will also provide corresponding emergency response plans according to the alarm level, such as evacuating the crew, starting the sprinkler system, and shutting down relevant equipment, so as to minimize the harm caused by the accident and facilitate the crew to quickly take effective emergency measures or escape strategies, thereby ensuring the life safety and health of the crew.

[0011] Optionally, the ammonia detection device includes a wired communication module, and the control device connects the wired communication modules of the plurality of ammonia detection devices in series to realize the series networking of the plurality of ammonia detection devices.

[0012] As described above, the ammonia detection equipment has a built-in wired communication module. The control equipment connects the wired communication modules of each ammonia detection device in series to realize data transmission with each ammonia detection device. Using wired communication modules and a series networking method to connect each ammonia detection device can bring a series of technical effects and optimizations, such as improved data transmission stability and real-time performance, enhanced system reliability, ease of maintenance and expansion, and cost-effectiveness.

[0013] Optionally, the ammonia detection device may also include a power distribution board and a storage battery;

[0014] The power distribution board is used to switch the power supply to the control equipment and provide the working voltage for the ammonia detection equipment;

[0015] The battery is used to provide backup power for the ammonia detection equipment.

[0016] As described above, the power distribution board of the ammonia detection equipment can regulate and distribute power to ensure a stable operating voltage for the ammonia detection equipment. The battery serves as a backup power source for the ammonia detection equipment, and can continue to supply power to the equipment when the main power supply fails or is interrupted, ensuring that the ammonia detection equipment can still work normally in emergency situations and provide necessary monitoring and alarm functions.

[0017] Optionally, the ammonia detection device includes a wireless communication module and an antenna module. The control device connects the wireless communication modules of the plurality of ammonia detection devices wirelessly to achieve wireless networking of the plurality of ammonia detection devices.

[0018] Based on the above, according to the deployment scheme, if a wireless deployment scheme is adopted, the ammonia detection equipment can also be equipped with a wireless communication module and an antenna module. The control equipment can wirelessly connect to the wireless communication modules of several ammonia detection equipment to achieve wireless networking with several ammonia detection equipment, thereby reducing wiring costs and complexity, making the deployment of ammonia detection equipment more flexible, and helping to quickly and accurately deploy ammonia detection equipment in the complex environment of ships. Furthermore, the wireless networking method makes the system more scalable, and it is easy to add new ammonia detection equipment.

[0019] Optionally, the ammonia detection device may also include a solar panel and a built-in battery;

[0020] The solar panel is used to charge the built-in battery using solar energy, and the built-in battery is used to provide operating voltage for the ammonia detection equipment.

[0021] Therefore, introducing solar panels and built-in batteries as the power solution for ammonia detection equipment not only improves the system's self-sufficiency and continuous operation capability, but also reduces maintenance and operating costs.

[0022] Optionally, the indicator light module of the ammonia detection device includes LED beads of various colors, and the main board module includes multiple logic circuits connected in parallel, each corresponding to a multiple LED bead of the indicator light module;

[0023] The motherboard module receives the ammonia concentration signal output by the gas concentration detection module. When the ammonia concentration is higher than different set values, it controls different logic circuits to be turned on, and controls the corresponding colored LED beads to display different levels of alarm lights.

[0024] As described above, by setting LED beads of different colors in the indicator module and setting multiple logic circuits in parallel in the main board module, each logic circuit independently controls one or more LED beads. The device has multiple preset ammonia concentration values. When the ammonia concentration is higher than a certain set value, the main board module will control the corresponding logic circuit to conduct and light up the corresponding color LED beads, providing intuitive visual indication for the crew.

[0025] Optionally, the different colored alarm lights include:

[0026] When the ammonia concentration is 0, the indicator light module does not light up;

[0027] When the ammonia concentration is between 0 and the first threshold, the indicator light module displays a flashing green light and the indicator light module at the first alarm point displays a solid green light.

[0028] When the ammonia concentration is between the first and second thresholds, the indicator light module displays a flashing blue light and the indicator light module at the first alarm point displays a solid blue light.

[0029] When the ammonia concentration is between the second and third thresholds, the indicator module displays a flashing yellow light and the indicator module for the first alarm point displays a solid yellow light.

[0030] When the ammonia concentration exceeds the third threshold, the indicator light module displays a flashing red light, and the indicator light module at the first alarm point displays a solid red light.

[0031] As described above, by designing multiple thresholds and corresponding light indicators, the device can issue different levels of warnings under different ammonia concentration conditions. Through flashing lights of different colors and constant lights, users can intuitively understand the current ammonia concentration status without a complicated interpretation process.

[0032] Optionally, the ammonia detection devices are arranged in a single-sided or double-sided manner, respectively in the ship's living quarters passage area, deck passage area, ammonia equipment danger area, and rescue and escape area.

[0033] Therefore, ammonia detection equipment should cover all areas on the ship where ammonia leaks may occur, including living quarters passageways, deck passageways, ammonia equipment hazard areas, and rescue and escape areas. By selecting appropriate layout methods and quantities, comprehensive monitoring and timely early warning of ammonia concentration can be ensured, and the ammonia detection equipment can issue warnings before the ammonia concentration reaches dangerous levels, providing sufficient escape and response time for the crew.

[0034] Optionally, the terminal computer is equipped with an intelligent warning model. The terminal computer calculates the ammonia concentration signal returned by each ammonia detection device through the intelligent warning model, and outputs at least one corresponding emergency response plan based on the ammonia concentration signal, diffusion range, and leakage area.

[0035] As described above, by deploying an intelligent warning model within the terminal computer, the ship safety management system can achieve real-time monitoring and risk assessment of ammonia concentration, and automatically generate corresponding emergency response plans. This not only improves the speed and accuracy of emergency response, but also reduces the likelihood and severity of accidents.

[0036] Optionally, the intelligent warning model performs deep learning and self-optimization based on the ammonia concentration signal and the corresponding emergency response plan.

[0037] As described above, during operation, the intelligent warning model continuously receives real-time data from the ammonia detection equipment and generates emergency response plans based on this data. The actual execution effects and subsequent feedback of these plans are collected and used as new training data to input into the model, enabling the intelligent warning model to perform deep learning, fine-tune and optimize the model parameters, and improve the accuracy and efficiency of the emergency response plans output by the intelligent warning model.

[0038] These and other aspects of this application will become more apparent in the description of the following embodiments(s). Attached Figure Description

Detailed Implementation

[0044] The technical solutions provided in this application will be further described below with reference to the accompanying drawings and embodiments. It should be understood that the system architecture and business scenarios provided in the embodiments of this application are mainly for illustrating possible implementations of the technical solutions of this application and should not be construed as the sole limitation on the technical solutions of this application. Those skilled in the art will recognize that the technical solutions provided in this application are equally applicable to similar technical problems as system architectures evolve and new business scenarios emerge.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. In case of any inconsistency, the meaning set forth in this specification or derived from the content described herein shall prevail. Furthermore, the terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit the scope of this application.

[0046] This application proposes an ammonia gas leak hazard warning system, mainly used in ammonia-fueled ships or ammonia equipment facilities, to provide intuitive warnings of hazardous areas after an ammonia gas leak. The system uses ammonia detection equipment deployed in multiple areas of the ship to detect the ammonia concentration in the air in real time and display different levels of alarm lights according to the concentration value, thereby guiding the ship's personnel or ammonia equipment staff to respond to emergencies and ensure the safety of personnel.

[0047] like Figure 1 As shown, the ammonia gas leak hazard warning system provided in this application embodiment includes a terminal computer 100 and a control device 200 arranged in the control room, and also includes several ammonia gas detection devices 300 arranged in multiple areas of the ship.

[0048] Each ammonia detection device 300 includes a gas concentration detection module, a main board module, and an indicator light module connected in sequence. The gas concentration detection module is used to detect the ammonia concentration in the air. The main board module has built-in logic circuits to receive data from the gas concentration detection module and control the conduction of the internal logic circuits according to different ammonia concentrations, thereby controlling the indicator light module to display different levels of alarm lights. The control device 200 is connected to the plurality of ammonia detection devices 300 and configures the power supply and signal transmission of each ammonia detection device 300. The terminal computer 100 is connected to the control device 200 and is used to configure and monitor the system, and provide corresponding emergency response plans according to the alarm levels of the ammonia detection devices 300.

[0049] This application provides an ammonia gas leak hazard warning system. By deploying ammonia detection devices in multiple areas of the ship and configuring them uniformly, the system can detect the ammonia concentration in the air in real time. Based on different ammonia concentrations, the system controls the conduction of internal logic circuits to determine the alarm level and control the indicator light module to display different levels of alarm lights, providing intuitive warning information to the crew. When the system detects an ammonia leak and triggers an alarm, the terminal computer will also provide corresponding emergency response plans based on the alarm level, such as evacuating the crew, activating the sprinkler system, and shutting down related equipment, to minimize the harm caused by the accident and facilitate the crew to quickly take effective emergency measures or escape strategies, thereby ensuring the crew's life safety and health.

[0050] The following is based on Figures 2-4 As shown, the specific structure and working principle of the ammonia gas leak hazard warning system provided in the embodiments of this application are described in detail.

[0051] Figure 2 The diagram shown is a structural diagram of the first type of ammonia gas leak hazard warning system provided in this application embodiment. (Refer to...) Figure 2 As shown, the ammonia gas leak hazard warning system of this application embodiment includes a terminal computer 3 and a control box 2 (i.e., the control equipment mentioned above) arranged in the control room, and several ammonia gas detection devices 1-1 arranged in multiple areas of the ship. The system adopts a series networking, connecting the terminal computer, control box and several ammonia gas detection devices in series to reduce redundant lines in the system. These several ammonia gas detection devices can be arranged in multiple areas of the ship, such as the living quarters passage area, deck passage area, ammonia equipment hazard area, and rescue and escape areas such as the apron or lifeboat, to achieve comprehensive ammonia gas leak monitoring. In specific arrangement, the horizontal spacing of the ammonia gas detection devices is no more than 2m, and they are arranged on one side along the length of the passage. When the passage width is large, they can be arranged on both sides. For non-hazardous areas or large open-air work areas, the horizontal spacing of the ammonia gas detection devices does not exceed 3m. If there are endpoints, they should be set at the endpoints and distributed at 2m intervals with the center points of both ends as the axis.

[0052] Specifically, the ammonia detection device in this embodiment includes a gas concentration detection module, a main board module, and an indicator light module connected in sequence. It also includes a wired communication module connected to the main board module. The gas concentration detection module is used to detect the ammonia concentration in the air and is the core detection component of the system. The main board module controls the conduction of its internal logic circuits according to different ammonia concentrations to determine the alarm level and control the indicator light module. The indicator light module displays different alarm lights according to the control of the main board module to provide intuitive warning information. The control box connects the wired communication modules of several ammonia detection devices in series, realizing a network connection between these devices and enabling data interaction. Through the control box, power supply and control logic configurations can also be configured for each ammonia detection module to ensure its normal operation.

[0053] In this embodiment, the terminal computer is connected to the control box, which controls each ammonia detection device. The terminal computer also performs overall system configuration and monitoring, and through a built-in intelligent warning model, provides at least one corresponding emergency response plan based on the alarm level of the ammonia detection devices, guiding the crew in emergency operations. By deploying the intelligent warning model within the terminal computer, the ship safety management system can achieve real-time monitoring and risk assessment of ammonia concentration and automatically generate corresponding emergency response plans. This not only improves the speed and accuracy of emergency response but also reduces the likelihood and severity of accidents. Furthermore, during operation, the intelligent warning model continuously receives real-time data from the ammonia detection devices and combines this data with emergency response content to generate emergency response plans. The actual implementation effects and subsequent feedback of these plans are collected and rational suggestions are provided to facilitate deep learning of the intelligent warning model, allowing for fine-tuning and optimization of model parameters, thereby improving the accuracy and efficiency of emergency response plans.

[0054] like Figure 3 As shown, the indicator light module of the ammonia detection device in this embodiment can include LED beads of various colors, such as green, blue, yellow, and red. The main board module includes multiple logic circuits connected in parallel, each corresponding to one of the LED beads in the indicator light module. The main board module receives the ammonia concentration signal output by the gas concentration detection module. Based on the hazard level of different ammonia concentrations, the main board module can also incorporate multiple ammonia concentration thresholds, such as 1.5ppm, 30ppm, 300ppm, and 1390ppm, to control the corresponding logic circuits to conduct according to different ammonia concentrations, thereby controlling the indicator light module to display the corresponding color alarm light. The control logic and alarm levels of this main board module are as follows:

[0055] Harmless state: When the gas concentration detection module does not detect any ammonia concentration, the logic circuit of the motherboard is not turned on, and the indicator light module does not light up, indicating that this area is safe and there is no ammonia residue.

[0056] Mild condition: When the gas concentration detection module detects an ammonia concentration below 1.5 ppm, the logic circuit connected to the green LED beads in the motherboard is triggered and outputs a flashing control signal. At this time, the green LED beads of the indicator module emit a green flashing light, indicating that ammonia can be detected in this area, but the concentration is below 1.5 ppm, and normal operation is possible.

[0057] Level 1 Alarm: When the gas concentration detection module detects an ammonia concentration between 1.5ppm and 30ppm, the logic circuit connected to the blue LED beads in the main board is triggered and outputs a flashing control signal. At this time, the blue LED beads of the indicator module emit a blue flashing light, indicating that the ammonia concentration detected in this area is less than 30ppm, which is a Level 1 alarm and may damage the eyes, skin, lungs, etc.

[0058] Level 2 Alarm: When the gas concentration detection module detects an ammonia concentration between 30 ppm and 300 ppm, the logic circuit connected to the yellow LED on the main board is triggered and outputs a flashing control signal. At this time, the yellow LED on the indicator module emits a slow yellow flashing light, indicating that the ammonia concentration detected in this area has exceeded 30 ppm, triggering a Level 2 alarm, which may endanger life and health. Furthermore, when the gas concentration detection module detects an ammonia concentration between 300 ppm and 1390 ppm, the logic circuit connected to the yellow LED on the main board outputs a rapid flashing control signal. At this time, the yellow LED on the indicator module emits a rapid yellow flashing light, indicating that the ammonia concentration in this area has exceeded 300 ppm, further reminding the crew of the danger in this area.

[0059] Level 3 alarm: When the gas concentration detection module detects that the ammonia concentration exceeds 1390ppm, the logic circuit connected to the red LED on the main board is triggered and outputs a fast flashing control signal. At this time, the red LED of the indicator module emits a fast flashing red light, indicating that the ammonia concentration detected in this area has exceeded 1390ppm, which is a Level 3 alarm and may be fatal.

[0060] In some embodiments, when the terminal computer receives an alarm signal from the first ammonia detection device, it can send a control signal to the ammonia detection device to control the logic circuit in the ammonia detection device to output a constant-on control signal, so as to control the LED beads of the indicator module connected to it to remain constantly lit, so as to remind the ammonia detection device in the area that it is the first device to detect ammonia leakage, that is, the area is the leak point or overflow point, so as to facilitate the crew to perform corresponding safety operations.

[0061] In some embodiments, the ammonia detection device further includes a power distribution board and a battery. The power distribution board can regulate and distribute power, switch the power supply to the control box, and provide operating voltage for the ammonia detection device. The battery can serve as a backup power source for the ammonia detection device, and can continue to supply power to the device when the main power supply fails or is interrupted, ensuring that the ammonia detection device can still work normally in emergency situations and provide necessary monitoring and alarm functions.

[0062] Figure 4 The diagram shown is a structural diagram of the second type of ammonia gas leak hazard warning system provided in this application embodiment. (Refer to...) Figure 4 As shown, the ammonia gas leak hazard warning system of this application embodiment includes a terminal computer 3 and a control box 2 (i.e., the control equipment mentioned above) arranged in the control room, and several ammonia gas detection devices 1-2 arranged in multiple areas of the ship. The system adopts wireless networking to wirelessly network the terminal computer, control box and several ammonia gas detection devices, thereby reducing the wiring cost and complexity of the system, making the deployment of ammonia gas detection devices more flexible, helping to quickly and accurately deploy ammonia gas detection devices in the complex environment of the ship, and the wireless networking method makes the system more scalable, and new ammonia gas detection devices can be easily added.

[0063] Specifically, the ammonia detection device in this embodiment includes a gas concentration detection module, a main board module, and an indicator light module connected in sequence. It also includes a wireless communication module connected to the main board module and an antenna module connected to the wireless communication module. The gas concentration detection module detects the ammonia concentration in the air. The main board module controls the conduction of its internal logic circuits according to different ammonia concentrations to determine the alarm level and control the indicator light module. The indicator light module displays different levels of alarm lights according to the control of the main board module, providing intuitive warning information. The control box is wirelessly connected to the wireless communication modules of several ammonia detection devices, enabling wireless networking of these devices. This allows for data interaction and control logic configuration with each ammonia detection device via a wireless communication protocol, ensuring the normal operation of each ammonia detection module.

[0064] In some embodiments, the ammonia detection device further includes a solar panel and a built-in battery. The solar panel is used to charge the built-in battery with solar energy, and the built-in battery is used to provide operating voltage for the ammonia detection device. This not only improves the system's self-sufficiency and continuous operation capability, but also reduces maintenance and operating costs.

[0065] The working principles of each ammonia detection device, control box, and terminal computer in this embodiment are the same as those of... Figure 2 The embodiments shown are consistent and will not be repeated here.

[0066] In summary, the ammonia gas leak hazard warning system provided in this application embodiment, through matrix networking, deploys ammonia detection equipment in multiple areas of the ship to detect and visually display the leakage and diffusion of ammonia gas. This allows crew members to receive hazard information using their own vision and determine the extent of the leak without the need for other equipment. Furthermore, this application embodiment uses a control box and terminal computer to uniformly manage and control multiple ammonia detection devices, ensuring system stability and reliability. By employing an intelligent warning model to automatically generate corresponding emergency response plans, it not only improves the speed and accuracy of emergency response but also reduces the likelihood and severity of accidents, effectively protecting the lives and health of crew members on ammonia-fueled ships. This system demonstrates high practicality and reliability.
