Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen fuel cells, and in particular to a hydrogen fuel cell management system for a hydrogen energy sightseeing boat. Background Art

[0002] As the world's dependence on fossil fuels decreases and attention is paid to renewable energy, hydrogen energy, as a clean and efficient form of energy, has gradually gained attention. Hydrogen energy is considered to be one of the important ways to achieve the goal of carbon neutrality and can be used in transportation, industrial production, energy storage and other fields. Especially in the marine transportation and sightseeing industries, the application of hydrogen energy helps to reduce carbon emissions and protect the marine ecological environment. Therefore, a hydrogen fuel cell management system for hydrogen sightseeing ships is needed.

[0003] The prior art, such as the invention patent application with announcement number CN114408105A, discloses an unmanned boat based on hydrogen fuel cell technology, including a hydrogen fuel cell management system, a human-computer interaction system, a communication system, an IMU, a global satellite positioning system, an obstacle analysis system, a laser radar device, a millimeter-wave radar device, a visual detection device, a drive analysis module, a drive servo system, a steering servo system, and a gear servo system. The present invention uses hydrogen fuel cells as the power source of the unmanned boat, making the energy supply of the ship greener and more environmentally friendly, providing an automatic driving function, introducing advanced automatic driving technology into the field of ships, and bringing a more intelligent, efficient, environmentally friendly, and convenient working environment to the freight operations and sightseeing tourism boat industries in inland rivers and offshore, reducing more labor intensity, and bringing greater social and economic benefits.

[0004] In view of the above scheme, the applicant of the present invention has found that the above technology has at least the following technical problems: 1. The existing hydrogen fuel cell thermal management system is not suitable for use in ships. Faced with the turbulent weather conditions in the ocean, the ocean temperature has a greater impact on the hydrogen fuel cell. In addition, the marine environment has serious salt spray. The radiators on the market cannot withstand the salt spray level in the ocean and are easily damaged. There is no ability to monitor the marine environment in real time, such as water temperature, salt spray concentration, wave height, etc. Hydrogen fuel cells may operate under inappropriate conditions, resulting in performance degradation or failure. In the changing marine environment, there is a lack of the ability to dynamically adjust cooling and maintenance strategies, which may cause battery overheating or other performance problems.

[0005] 2. Existing technologies lack cooling strategies for specific environmental conditions, which may lead to inefficient cooling and affect the life and performance of fuel cells. In high-salinity and corrosive environments, the lack of assessment of material corrosion resistance and coolant selection may lead to equipment damage. At the same time, the lack of monitoring of battery operating status may result in potential faults not being discovered in a timely manner, increasing the risk of accidents. In the event of extreme weather or other emergencies, the lack of the ability to respond quickly and adjust strategies may affect ship safety. Summary of the invention

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0022] Figure 1 It is a schematic diagram of the connection of the system modules of the present invention. DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Embodiments of the present invention Figure 1 As shown, a hydrogen fuel cell management system for a hydrogen sightseeing boat includes: a sea area environment assessment coefficient acquisition module, a cooling and maintenance strategy analysis module, a sea area dynamic impact factor acquisition module, a battery operation assessment coefficient acquisition module, a battery operation parameter adjustment module and a database.

[0025] The cooling and maintenance strategy analysis module is connected to the sea area environment assessment coefficient acquisition module and the sea area dynamic impact factor acquisition module respectively, the battery operation assessment coefficient acquisition module is connected to the sea area dynamic impact factor acquisition module and the battery operation parameter adjustment module respectively, and the database is connected to the cooling and maintenance strategy analysis module and the battery operation parameter adjustment module respectively.

[0026] Sea environment assessment coefficient acquisition module: used to obtain the sea environment data corresponding to the hydrogen fuel cell group of the target ship at the current moment, and then analyze and obtain the sea environment assessment coefficient corresponding to the hydrogen fuel cell group.

[0027] In a specific embodiment, the marine environment data includes salt spray concentration, organic matter concentration in water, and water turbulence intensity corresponding to each water depth level.

[0028] It should be noted that dedicated salt spray sensors, such as gas sensors, are used to monitor the concentration of salt spray in the air in real time. These sensors can be deployed at different locations on the ship to collect salt spray data in the surrounding environment, and use fluorescence spectrometers or near-infrared sensors to detect the concentration of organic matter in the water. These sensors can obtain concentration data by analyzing the light absorption and scattering characteristics of organic matter in the water, and use ADCP to measure the turbulence intensity of the water body. ADCP can measure the turbulence intensity of water flow at different depths through the Doppler effect of sound waves, thereby obtaining the turbulence intensity.

[0029] In another specific embodiment, the analysis obtains the marine environment assessment coefficient corresponding to the hydrogen fuel cell group. The specific analysis process is as follows: the salt spray concentration corresponding to the hydrogen fuel cell group, the organic matter concentration in the water, and the water turbulence intensity corresponding to each water depth level are recorded as , and ,in, Indicates the number corresponding to each water depth level, , n is any integer greater than 2, substitute it into the calculation formula The marine environment assessment coefficient corresponding to the hydrogen fuel cell group is obtained ,in, , , They are the standard salt spray concentration corresponding to the set hydrogen fuel cell group, the standard organic matter concentration in water, and the standard water turbulence intensity corresponding to the water depth level. , , They are the weight factors corresponding to the salt spray concentration of the hydrogen fuel cell group, the weight factors corresponding to the organic matter concentration in the water, and the weight factors corresponding to the turbulence intensity of the water body at the water depth level. Represents a natural constant.

[0030] It should be noted that , , Both are greater than 0 and less than 1.

[0031] It should also be noted that through the summary of a large amount of research data and experimental data, the standard salt spray concentration, standard organic matter concentration in water, and standard water turbulence intensity corresponding to the water depth level of the hydrogen fuel cell group are set according to professional institutions and research institutions. At the same time, based on the professional knowledge and research basis of experts in the field, and discussed and confirmed with industry organizations or professional institutions, the experts set the weight factors corresponding to the salt spray concentration of the hydrogen fuel cell group, the weight factors corresponding to the organic matter concentration in water, and the weight factors corresponding to the water turbulence intensity at the water depth level according to their own experience and knowledge.

[0032] It needs to be explained again that the standard salt spray concentration, standard organic matter concentration in water, and standard water turbulence intensity corresponding to the water depth level are the salt spray concentration threshold, the organic matter concentration threshold in water, and the water turbulence intensity threshold corresponding to the water depth level, for example: the standard salt spray concentration is 5, the standard organic matter concentration in water is 5, and the standard water turbulence intensity corresponding to the water depth level is 0.5.

[0033] Cooling and maintenance strategy analysis module: used to obtain the water temperature, air temperature and salinity corresponding to the hydrogen fuel cell group, and analyze the cooling and maintenance strategy of the hydrogen fuel cell group of the target ship based on the marine environment assessment coefficient corresponding to the hydrogen fuel cell group.

[0034] In a specific embodiment, the cooling strategy of the hydrogen fuel cell group of the target ship is analyzed, and the specific analysis process is as follows: A1. Compare the water temperature, air temperature and salinity corresponding to the hydrogen fuel cell group with the water temperature, air temperature and salinity corresponding to each cooling strategy collection in the database. If the water temperature, air temperature and salinity corresponding to the hydrogen fuel cell group are the same as the water temperature, air temperature and salinity corresponding to a cooling strategy collection in the database, then the cooling strategy collection in the database is recorded as the cooling strategy collection corresponding to the hydrogen fuel cell group.

[0035] A2. Compare the sea area environment assessment coefficient corresponding to the hydrogen fuel cell group with the sea area environment assessment coefficient interval corresponding to each cooling strategy in the corresponding cooling strategy collection in the database. If the sea area environment assessment coefficient corresponding to the hydrogen fuel cell group is within the sea area environment assessment coefficient interval corresponding to a certain cooling strategy in the corresponding cooling strategy collection in the database, then use the cooling strategy in the corresponding cooling strategy collection in the database as the cooling strategy for the target ship's hydrogen fuel cell group. In this way, analyze the cooling strategy of the target ship's hydrogen fuel cell group.

[0036] In another specific embodiment, the maintenance strategy of the hydrogen fuel cell group of the target ship is analyzed, and the specific analysis process is as follows: B1. The water temperature, air temperature and salinity corresponding to the hydrogen fuel cell group are compared with the water temperature, air temperature and salinity corresponding to each maintenance strategy collection in the database. If the water temperature, air temperature and salinity corresponding to the hydrogen fuel cell group are the same as the water temperature, air temperature and salinity corresponding to a maintenance strategy collection in the database, then the maintenance strategy collection in the database is recorded as the maintenance strategy collection corresponding to the hydrogen fuel cell group.

[0037] B2. Compare the sea area environment assessment coefficient corresponding to the hydrogen fuel cell group with the sea area environment assessment coefficient intervals corresponding to each maintenance strategy in the corresponding maintenance strategy collection in the database. If the sea area environment assessment coefficient corresponding to the hydrogen fuel cell group is within the sea area environment assessment coefficient interval corresponding to a maintenance strategy in the corresponding maintenance strategy collection in the database, then use the maintenance strategy in the corresponding maintenance strategy collection in the database as the maintenance strategy for the target ship's hydrogen fuel cell group. In this way, the maintenance strategy of the target ship's hydrogen fuel cell group is analyzed.

[0038] It should be noted that a multi-parameter water quality monitor is used for data collection, and a multi-parameter water quality monitor is installed on the bottom of the hull or at an appropriate underwater location to monitor the water temperature in real time. A weather station or meteorological sensor is used, which can measure air temperature and humidity and obtain data through a microcontroller. A multi-parameter water quality monitor is selected, which can usually measure multiple water quality parameters such as water temperature, salinity, and pH value at the same time.

[0039] In the embodiments of the present invention, by acquiring marine environmental data in real time, such as water temperature, air temperature and salinity, the system can dynamically adapt to different environmental conditions to ensure that the hydrogen fuel cell operates in the best state. The cooling and maintenance strategies are analyzed according to the marine environmental assessment coefficient, and the cooling system of the hydrogen fuel cell can be optimized to reduce energy consumption, improve overall operating efficiency, and extend the service life of the battery. According to the environmental assessment coefficient, the system can formulate a reasonable maintenance plan, reduce unnecessary maintenance work, improve the reliability and availability of equipment, optimize the cooling and maintenance strategies of the hydrogen fuel cell, reduce the negative impact on the environment, promote sustainable green shipping, and ultimately reduce operating costs by improving energy efficiency and reducing failure rates, thereby improving the economic benefits of hydrogen sightseeing ships.

[0040] Sea area dynamic impact factor acquisition module: used to obtain the sea area dynamic data corresponding to the hydrogen fuel cell group. The sea area dynamic data includes the relative flow velocity of the ship, the relative wind speed of the ship and the wave height, so as to analyze and obtain the sea area dynamic assessment coefficient corresponding to the hydrogen fuel cell group, and according to the sea area environmental assessment coefficient corresponding to the hydrogen fuel cell group, further analyze and obtain the sea area dynamic impact factor corresponding to the hydrogen fuel cell group.

[0041] It should be noted that the GPS device on the ship is used to obtain the current position and speed of the ship, and the inertial navigation system (INS) is combined to improve accuracy. The relative flow velocity can be obtained by calculating the difference between the actual speed of the ship in the water and the water flow velocity. A flow velocity sensor is installed under the hull to directly measure the water flow velocity and compare it with the ship's speed to obtain the relative flow velocity. An anemometer, such as a wind speedometer, is installed on the ship to measure the wind speed and wind direction in real time. By combining the measured wind speed with the ship's speed and heading, the relative wind speed can be obtained. The height and characteristics of the surface waves can be measured using radar or sonar technology to obtain wave data.

[0042] Once again, it should be noted that the relative flow velocity refers to the relative speed of movement between the ship and the ocean current. It can be calculated by vector calculation based on the speed of the ship and the speed of the ocean current. When the relative flow velocity is high, the ship may need a larger power output from the hydrogen fuel cell to overcome the resistance of the water flow; in the case of downstream, the effective speed of the ship will increase, which may reduce energy consumption. Wind speed refers to the flow speed of air, usually expressed in meters per second (m / s) or knots. An increase in wind speed will increase the resistance of the ship when sailing, especially in crosswind conditions. Changes in wind speed will affect the heading and stability of the ship, and the speed and heading may need to be adjusted to maintain stable navigation. In high wind conditions, the ship may need additional power to maintain speed and direction, thereby increasing the load and energy consumption of the hydrogen fuel cell.

[0043] In a specific embodiment, the analysis obtains the sea area dynamic assessment coefficient corresponding to the hydrogen fuel cell group. The specific analysis process is as follows: the relative flow velocity of the ship, the relative wind speed of the ship and the wave height corresponding to the hydrogen fuel cell group are respectively recorded as , and , substitute into the calculation formula The dynamic assessment coefficient of the sea area corresponding to the hydrogen fuel cell group is obtained ,in, , , They are the standard ship relative flow speed, standard ship relative wind speed, and standard wave height corresponding to the set hydrogen fuel cell group. , , They are the weight factors corresponding to the relative flow velocity of the hydrogen fuel cell group ship, the weight factors corresponding to the relative wind speed of the ship, and the weight factors corresponding to the wave height. Represents a natural constant.

[0044] It should be noted that , , Both are greater than 0 and less than 1.

[0045] It should also be noted that through the summary of a large amount of research data and experimental data, the standard ship relative flow speed, standard ship relative wind speed, and standard wave height corresponding to the hydrogen fuel cell group are set according to professional institutions and research institutions. At the same time, based on the professional knowledge and research basis of experts in the field, and discussed and confirmed with industry organizations or professional institutions, the experts set the weight factors corresponding to the relative flow speed of the hydrogen fuel cell group ship, the weight factors corresponding to the relative wind speed of the ship, and the weight factors corresponding to the wave height according to their own experience and knowledge.

[0046] It should be noted once again that the standard ship relative flow speed, the standard ship relative wind speed, and the standard wave height are respectively the ship relative flow speed threshold, the ship relative wind speed threshold, and the wave height threshold, for example: the standard ship relative flow speed is 2, the standard ship relative wind speed is 15, and the standard wave height is 1.

[0047] In another specific embodiment, the analysis obtains the dynamic impact factor of the sea area corresponding to the hydrogen fuel cell group. The specific analysis process is as follows: Substitute the sea area environment assessment coefficient and the sea area dynamic assessment coefficient corresponding to the hydrogen fuel cell group into the calculation formula The dynamic impact factor of the sea area corresponding to the hydrogen fuel cell group is obtained ,in, , They are respectively the weight factor corresponding to the marine environment assessment coefficient of the set hydrogen fuel cell group and the weight factor corresponding to the marine dynamic assessment coefficient, and e represents a natural constant.

[0048] It should be noted that , Both are greater than 0 and less than 1.

[0049] It should also be noted that, based on the expertise and research of experts in the field, and after discussion and confirmation with industry organizations or professional institutions, the experts set the weight factors corresponding to the marine environmental assessment coefficient of the hydrogen fuel cell group and the weight factors corresponding to the marine dynamic assessment coefficient based on their own experience and knowledge.

[0050] Battery operation evaluation coefficient acquisition module: used to obtain the operating status data corresponding to the hydrogen fuel cell group. The operating status data includes hydrogen purity, hydrogen consumption rate and oxygen consumption, and according to the dynamic impact factor of the sea area corresponding to the hydrogen fuel cell group, the battery operation evaluation coefficient corresponding to the hydrogen fuel cell group is analyzed and obtained.

[0051] It should be noted that hydrogen sensors are installed in the hydrogen storage equipment of the target ship to monitor the purity of hydrogen in real time. Flow meters are installed in the hydrogen supply pipeline to measure the flow rate of hydrogen in real time (usually in liters / minute or cubic meters / hour). Hydrogen consumption rate = flow meter reading hydrogen. Flow meters are also installed in the oxygen supply pipeline to measure the flow rate of oxygen in real time. Hydrogen consumption rate = flow meter reading oxygen.

[0052] In a specific embodiment, the analysis obtains the battery operation evaluation coefficient corresponding to the hydrogen fuel cell group. The specific analysis process is as follows: the hydrogen purity, hydrogen consumption rate and oxygen consumption corresponding to the hydrogen fuel cell group are respectively recorded as , and , substitute into the calculation formula The battery operation evaluation coefficient corresponding to the hydrogen fuel cell group is obtained ,in, , , They are the standard hydrogen purity, standard hydrogen consumption rate, and standard oxygen consumption corresponding to the set hydrogen fuel cell group. , , They are the weight factor corresponding to the hydrogen purity of the set hydrogen fuel cell group, the weight factor corresponding to the hydrogen consumption rate, and the weight factor corresponding to the oxygen consumption. Represents a natural constant.

[0053] It should be noted that , , Both are greater than 0 and less than 1.

[0054] It should also be noted that through the summary of a large amount of research data and experimental data, the standard hydrogen purity, standard hydrogen consumption rate, and standard oxygen consumption corresponding to the hydrogen fuel cell group are set according to professional institutions and research institutions. At the same time, based on the professional knowledge and research basis of experts in the field, they are discussed and confirmed with industry organizations or professional institutions. Experts set the weight factors corresponding to the hydrogen purity of the hydrogen fuel cell group, the weight factors corresponding to the hydrogen consumption rate, and the weight factors corresponding to the oxygen consumption based on their own experience and knowledge.

[0055] It should be noted again that the standard hydrogen purity, the standard hydrogen consumption rate, and the standard oxygen consumption are the hydrogen purity threshold, the hydrogen consumption rate threshold, and the oxygen consumption threshold, respectively. For example: the standard hydrogen purity is 99, the standard hydrogen consumption rate is 0.5, and the standard oxygen consumption is 0.5.

[0056] Battery operation parameter adjustment module: used to analyze the battery operation parameter adjustment value of the hydrogen fuel cell group according to the battery operation evaluation coefficient corresponding to the hydrogen fuel cell group, and adjust the hydrogen fuel cell group according to the battery operation parameter adjustment value.

[0057] In a specific embodiment, the battery operating parameter adjustment values ​​of the hydrogen fuel cell group are analyzed, and the specific analysis process is as follows: the battery operation evaluation coefficient corresponding to the hydrogen fuel cell group is compared with the battery operation evaluation coefficient interval corresponding to each battery operation parameter adjustment value in the database. If the battery operation evaluation coefficient corresponding to the hydrogen fuel cell group is within the battery operation evaluation coefficient interval corresponding to a battery operation parameter adjustment value in the database, then the battery operation parameter adjustment value in the database is used as the battery operation parameter adjustment value of the hydrogen fuel cell group. In this way, the battery operation parameter adjustment value of the hydrogen fuel cell group is analyzed.

[0058] In a specific embodiment, the database is used to store the water temperature, air temperature and salinity corresponding to each cooling strategy collection and the sea environment assessment coefficient interval corresponding to each cooling strategy in the cooling strategy collection, as well as to store the water temperature, air temperature and salinity corresponding to each maintenance strategy collection and the sea environment assessment coefficient interval corresponding to each maintenance strategy in the maintenance strategy collection. The database is also used to store the battery operation assessment coefficient interval corresponding to each battery operation parameter adjustment value.
