[0002] In the modern hydrogen production industry, hydrogen, a highly promising clean energy source, is seeing its applications expand. However, hydrogen is flammable and explosive. A leak could potentially cause serious safety incidents, such as explosions and fires, posing a significant threat to life and property. Therefore, timely and accurate detection of hydrogen leaks and the implementation of effective remedial measures are crucial. Currently, a key issue with existing hydrogen leak detection and remediation systems is the lack of effective interoperability between their components. Traditional detection systems often only independently measure hydrogen concentrations. When a leak is detected, they are unable to quickly and automatically coordinate with subsequent evacuation and emergency response equipment. For example, after the detection module detects a hydrogen leak, manual intervention is required to activate the evacuation mechanism. This delay allows hydrogen to continue to spread, increasing safety risks. Furthermore, even after the evacuation mechanism is activated, due to a lack of real-time integration with detection data, it often cannot accurately adjust according to the severity of the leak, potentially resulting in incomplete or over-evacuation. This problem of loose linkage between components makes the existing hydrogen leakage treatment system inefficient when facing sudden leakage incidents, and unable to control the dangerous situation in a timely and effective manner.

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 This is the block diagram of Benshen's high-efficiency hydrogen leak explosion detector and rapid emptying linkage system; Figure 2 This is a flow chart of the emergency response method for this application. DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] See also Figure 1-Figure 2 Traditional technical solutions, for example, face the following technical challenges: Hydrogen leakage is a serious safety hazard in hydrogen production. Hydrogen is flammable and explosive. If a leak occurs and is not promptly detected and addressed, it can cause a major safety incident, such as an explosion. Existing hydrogen leak detection and treatment systems suffer from issues such as delayed detection, limited treatment measures, and a lack of effective coordination between components, making them unable to meet the needs of efficient and safe hydrogen production.

[0018] Based on this, this embodiment provides a high-efficiency hydrogen leak explosion detector and rapid emptying linkage system, including a hydrogen concentration detection module, a data processing module, a rapid emptying device, an emergency processing module and a communication module; the hydrogen concentration detection module is used to collect hydrogen concentration data in the environment surrounding the hydrogen production equipment in real time, and transmit the collected data to the data processing module; the data processing module receives the data transmitted by the hydrogen concentration detection module, analyzes and processes the data based on a preset algorithm, and determines whether a hydrogen leak occurs and the leakage level; the rapid emptying device is communicatively connected to the data processing module, and when the data processing module determines that a hydrogen leak occurs, the corresponding emptying operation is performed according to the leakage level; after the rapid emptying device performs the emptying operation, the emergency processing module initiates corresponding emergency processing measures according to the leakage level; the communication module is used to realize data transmission and interaction between modules.

[0019] It is worth mentioning that: this embodiment proposes an efficient hydrogen leak explosion detector and rapid emptying linkage system, the core of which is to build a complete system including a hydrogen concentration detection module, a data processing module, a rapid emptying device, an emergency processing module and a communication module. The modules form an organic whole through clear functional division and interactive relationships. The hydrogen concentration detection module is responsible for collecting hydrogen concentration data in the environment surrounding the hydrogen production equipment in real time and transmitting it to the data processing module. After receiving the data, the data processing module analyzes and processes the data based on the preset algorithm to determine whether a hydrogen leak has occurred and the level of leakage. The rapid emptying device performs the corresponding emptying operation according to the judgment result of the data processing module. After the emptying operation, the emergency processing module initiates the corresponding emergency treatment measures. The communication module ensures smooth data transmission and interaction between modules.

[0020] The technical effects achieved by the above scheme include: the technical scheme of this embodiment realizes real-time monitoring, accurate judgment and rapid processing of hydrogen leakage through the collaborative work of multiple modules. First, the hydrogen concentration detection module can collect data in real time to ensure timely detection of leakage. The preset algorithm of the data processing module can conduct in-depth analysis of the data, accurately judge the leakage level, and provide a basis for subsequent processing. The rapid emptying device performs different emptying operations according to the leakage level, thereby improving processing efficiency. The hierarchical response measures of the emergency processing module further enhance the security of the system. The communication module ensures the flow of information between the modules, so that the entire system can operate efficiently and coordinated. This linkage system greatly reduces the risk of safety accidents caused by hydrogen leakage and improves the safety and reliability of the hydrogen production process.

[0021] Traditional solutions present the following technical challenges: Hydrogen leaks can occur at various locations around hydrogen production equipment. Improper sensor distribution can create blind spots, preventing timely detection of leaks. Existing hydrogen detection systems often lack scientific sensor placement, failing to fully cover the environment surrounding the hydrogen production equipment, thus impacting detection accuracy and timeliness.

[0022] Based on this, the hydrogen concentration detection module includes multiple hydrogen sensors, which are distributed in a matrix around the hydrogen production equipment to collect hydrogen concentration data in all directions.

[0023] It is worth noting that this embodiment further defines the hydrogen concentration detection module described above, characterized in that the module includes multiple hydrogen sensors distributed in a matrix around the hydrogen production equipment. This matrix arrangement enables the sensors to collect hydrogen concentration data in all directions, avoiding the existence of detection blind spots.

[0024] The technical effects achieved by the above solution include: Through the matrix-distributed arrangement of multiple hydrogen sensors, the technical solution of this embodiment enables comprehensive monitoring of the environment surrounding the hydrogen production equipment. This distribution ensures that any hydrogen leak occurring at any location will be detected by at least one sensor, significantly improving detection reliability. Compared to traditional single-point detection or unevenly distributed sensor systems, the matrix-distributed system can more accurately determine the location and scope of the leak source, providing more precise information for subsequent evacuation and emergency response. Furthermore, the data from multiple sensors can be mutually verified, improving the accuracy of detection results and reducing the possibility of misjudgment.

[0025] For example, traditional technical solutions have the following technical problems: in hydrogen leak detection, it is not enough to simply determine whether a leak has occurred. It is also necessary to accurately assess the severity of the leak so that appropriate treatment measures can be taken. Existing detection systems are often only able to perform simple leak judgments and are unable to scientifically classify leak levels, resulting in a lack of targeted treatment measures, which may cause resource waste or untimely treatment. Based on this, the data processing module has a built-in leak level determination model, which divides hydrogen leak levels into level one, level two, and level three leaks; when the hydrogen concentration is lower than the first threshold, it is determined to be no leak; when the hydrogen concentration is greater than or equal to the first threshold and less than the second threshold, it is determined to be a level one leak; when the hydrogen concentration is greater than or equal to the second threshold and less than the third threshold, it is determined to be a level two leak; when the hydrogen concentration is greater than or equal to the third threshold, it is determined to be a level three leak, where the first threshold < the second threshold < the third threshold.

[0026] It's worth noting that this embodiment refines the data processing module from the previous embodiment, featuring a built-in leakage level determination model that categorizes hydrogen leakage into level one, level two, and level three. The model determines the leakage level based on a comparison of hydrogen concentration with different thresholds. When the hydrogen concentration is below the first threshold, it's determined to be no leakage; when the hydrogen concentration is greater than or equal to the first threshold and less than the second threshold, it's determined to be a level one leakage; when the hydrogen concentration is greater than or equal to the second threshold and less than the third threshold, it's determined to be a level two leakage; and when the hydrogen concentration is greater than or equal to the third threshold, it's determined to be a level three leakage, where the first threshold < the second threshold < the third threshold.

[0027] The technical effects achieved by the above scheme include: the leakage level determination model of this embodiment realizes a graded assessment of hydrogen leakage by setting multiple thresholds. This grading method enables the system to take different treatment measures according to the severity of the leak, thereby improving the pertinence and effectiveness of the treatment. For a level one leak, the system can take relatively mild treatment measures, such as only activating the alarm device; for a level two leak, the system can increase the emptying force and activate some emergency measures; for a level three leak, the system can activate comprehensive emergency treatment measures to ensure safety. This graded treatment method not only improves treatment efficiency, but also effectively saves resources and avoids unnecessary waste. At the same time, accurate leakage level determination also provides an important basis for subsequent accident investigation and analysis.

[0028] For example, traditional technical solutions have the following technical problems: in the treatment of hydrogen leakage, the emptying flow rate needs to be precisely controlled according to the leakage level. If the emptying flow rate is too large, it may cause energy waste; if the emptying flow rate is too small, the leaked hydrogen cannot be removed in a timely and effective manner, increasing the safety risk. Existing emptying devices are often unable to flexibly adjust the emptying flow rate according to the leakage level, resulting in unsatisfactory treatment effects. Based on this, the rapid emptying device includes a plurality of exhaust pipes and electric valves, and the electric valves are arranged on the exhaust pipes. The data processing module controls the opening of different numbers of electric valves according to the leakage level to achieve different emptying flows.

[0029] It is worth mentioning that this embodiment further defines the rapid emptying device in the above embodiment, and is characterized in that the device includes multiple exhaust pipes and electric valves, the electric valves are arranged on the exhaust pipes, and the data processing module controls the opening of different numbers of electric valves according to the leakage level to achieve different emptying flow rates.

[0030] The technical effects achieved by the above solution include: The technical solution of this embodiment achieves precise control of the emptying flow by providing multiple exhaust pipes and electric valves and controlling the number of valves opened according to the leakage level. For different levels of leakage, the system can automatically adjust the number of valves opened to provide an appropriate emptying flow. This intelligent control method not only improves the emptying efficiency but also effectively saves energy. Compared with traditional fixed-flow emptying devices, this technical solution can better adapt to leaks of varying severity, ensuring that the hydrogen concentration is reduced to a safe range in the shortest possible time, greatly improving the safety and reliability of the system.

[0031] For example, traditional technical solutions have the following technical problems: when assessing the risk of hydrogen leakage, existing methods often only consider a single factor, such as hydrogen concentration, while ignoring the diffusion characteristics and spatial distribution of hydrogen in the air. This single-factor assessment method cannot fully and accurately reflect the risk level of hydrogen leakage, and may lead to underestimation or overestimation of the risk, thereby affecting the effectiveness of treatment measures. Based on this, the data processing module calculates the risk coefficient of hydrogen leakage based on the following formula: ; in, Indicates the risk factor; For continuous time The hydrogen concentration function; is the attenuation coefficient, reflecting the natural diffusion characteristics of hydrogen in the air; is the detection start time; is the current time; For the The coordinates of the sensors; The estimated coordinates of the leak source of the hydrogen production equipment; is the number of sensors involved in the calculation.

[0032] Numerator integral term: Represents the time from the start of detection To current time The cumulative value of hydrogen concentration after time decay within . For continuous time The hydrogen concentration function reflects the trend of hydrogen concentration over time. is the time decay factor, The attenuation factor reflects the natural diffusion characteristics of hydrogen in the air. Over time, hydrogen diffuses and dilutes, reducing its concentration. The attenuation factor simulates this process exponentially, minimizing the impact of concentration data further in time. This approach avoids biased hazard assessments caused by insufficient diffusion of early concentration data and better reflects the dynamic changes in hydrogen concentration in real-world scenarios.

[0033] Denominator integral term: It serves as a normalization factor. It calculates the cumulative value of the time decay factor over the same time period. By dividing the cumulative hydrogen concentration in the numerator by the denominator, the time-weighted average hydrogen concentration value is obtained. This normalization process makes the calculated hazard factor more comparable and reasonable, eliminates the impact of different testing durations, and ensures the consistency of hazard factor calculations across different testing cycles.

[0034] Spatial parameter items: Used to assess the spatial hazard of hydrogen leakage. For the The coordinates of the sensors, are the estimated coordinates of the hydrogen production equipment leakage source, is the number of sensors involved in the calculation. This formula first calculates the sum of the squares of the Euclidean distances from each sensor to the estimated location of the leak source, then takes the average and squares it to obtain the average spatial distance. The closer the area is to the leak source, the higher the hydrogen concentration and the greater the potential for danger. This parameter quantifies the spatial location factor and incorporates it into the hazard factor calculation. This allows the assessment to consider not only changes in concentration over time but also the spatial distribution characteristics. Compared to traditional assessment methods based solely on concentration, this method can more comprehensively and accurately reflect the true danger level of a hydrogen leak.

[0035] This formula combines the dynamic changes in concentration in the time dimension with the distribution characteristics in the spatial dimension, and obtains the risk coefficient of hydrogen leakage through scientific mathematical calculations. .

[0036] The larger the value, the higher the risk of hydrogen leakage. The system can formulate more targeted emergency strategies based on this value, such as adjusting the emptying force, initiating emergency measures of different levels, etc., thereby effectively reducing safety risks. Compared with the traditional single-factor evaluation method, it has significantly improved in accuracy and practicality.

[0037] It is worth mentioning that this embodiment proposes that the data processing module calculates the risk factor of hydrogen leakage based on the following formula: in, Indicates the risk factor; For continuous time The hydrogen concentration function; is the attenuation coefficient, reflecting the natural diffusion characteristics of hydrogen in the air; is the detection start time; is the current time; For the The coordinates of the sensors; is the estimated coordinates of the leak source of the hydrogen production equipment; is the number of sensors involved in the calculation.

[0038] The technical effects achieved by the above solution include: the formula of this embodiment creatively takes time and space factors into consideration, and introduces the time attenuation factor , more accurately reflects the trend of hydrogen concentration change over time. As time goes by, hydrogen will naturally diffuse in the air and the concentration will gradually decrease. The time decay factor can well reflect this characteristic. At the same time, the spatial distribution parameter in the formula By comprehensively considering the location relationship between the sensor and the leak source, the spatial hazard of the leak can be assessed. The closer the area is to the leak source, the higher the risk factor. This multi-factor comprehensive assessment method greatly improves the accuracy of hazard assessment, enabling the system to formulate more scientific treatment strategies and implement more effective emergency measures, thereby reducing safety risks.

[0039] For example, the traditional technical solution has the following technical problems: In the treatment of hydrogen leakage, how to determine the optimal emptying power is a key issue. If the emptying power is too large, it will cause energy waste; if the emptying power is too small, it will not be able to effectively and timely remove the leaked hydrogen. Existing emptying devices often use fixed power or empirical estimation methods, and cannot dynamically adjust the emptying power according to actual conditions, resulting in low processing efficiency. Based on this, the optimal emptying power of the rapid emptying device is Calculated by the following formula: ; in, is the air density; is the volume of the detection area; is the time rate of change of hydrogen concentration; is the divergence of the hydrogen concentration field; is the gas constant; is the ambient temperature; is the molar mass of hydrogen; is the efficiency coefficient of the emptying device.

[0040] Density and volume terms: middle, represents the air density, is the volume of the detection area. The product of these two terms represents the total mass of air within the detection area. In a hydrogen leak scenario, the leaked hydrogen must be expelled from the detection area. The total mass of air is a fundamental parameter, closely related to the amount of hydrogen to be expelled and the required exhaust power. A larger detection area volume or higher air density means that, for the same amount of hydrogen leaked, more energy is required to propel the air and expel the hydrogen. Therefore, this factor is a fundamental consideration in calculating exhaust power.

[0041] Fluid mechanics terms: Based on the continuity equation in fluid mechanics, it is used to describe the diffusion law of hydrogen in the air. Indicates the time rate of change of hydrogen concentration, reflecting the increase or decrease trend of hydrogen concentration over time. For example, continuous leakage of hydrogen will make this value positive, while gradual diffusion and dilution of hydrogen will make this value decrease. is the divergence of the hydrogen concentration field, describing the diffusion flux of hydrogen in space—that is, the diffusion velocity and flow rate of hydrogen in all directions. The combination of these two accurately characterizes the dynamic diffusion behavior of hydrogen in both space and time. This equation allows us to calculate the diffusion velocity and direction of hydrogen, and thus determine the required exhaust power to effectively contain and expel hydrogen from the detection area.

[0042] Gas state parameters: Involving gas state parameters, among which is the gas constant, is the ambient temperature, is the molar mass of hydrogen. The combination of these three items reflects the application of the ideal gas state equation, which is used to establish a relationship between the amount of hydrogen substance and physical quantities such as pressure and volume. When calculating the emptying power, this formula can convert the physical quantity of hydrogen into parameters related to power calculation according to the ambient temperature and the characteristics of hydrogen itself, ensuring that the calculation results conform to the actual physical scenario. For example, in a high temperature environment, the movement of gas molecules intensifies, and a larger emptying power is required to control the diffusion of hydrogen. This formula introduces the temperature parameter can accurately reflect this impact.

[0043] Efficiency coefficient term: in is the efficiency coefficient of the emptying device, which reflects the ability of the emptying device to convert input energy into effective exhaust air flow energy. In actual applications, there is energy loss in the emptying device, and not all input power can be fully used to exhaust hydrogen. The efficiency coefficient is used to correct the ideal calculated power. Take the reciprocal Indicates the multiple relationship between the actual required emptying power and the ideal power under the condition of considering efficiency loss, ensuring the calculated optimal emptying power It is a value that conforms to the actual operation of the equipment, avoiding insufficient power calculation or energy waste due to ignoring efficiency issues.

[0044] This formula takes into account multiple factors such as fluid mechanics, gas physical parameters, and equipment efficiency, and calculates the optimal emptying power of the rapid emptying device through scientific and rigorous mathematical relationships. The system can dynamically adjust the operating parameters of the emptying device based on the calculation results, ensuring the effective removal of hydrogen and reducing safety risks while achieving rational energy utilization. Compared with traditional empirical estimates or simple model calculations, it has significant advantages in accuracy and energy saving.

[0045] It is worth mentioning that: this embodiment proposes the optimal emptying power of the rapid emptying device Calculated by the following formula: in, is the air density; is the volume of the detection area; is the time rate of change of hydrogen concentration; is the divergence of the hydrogen concentration field; is the gas constant; is the ambient temperature; is the molar mass of hydrogen; is the efficiency coefficient of the emptying device.

[0046] The technical effects achieved by the above solution include: the formula of this embodiment is based on the continuity equation in fluid mechanics , which scientifically describes the diffusion law of hydrogen in the air. By considering the time rate of change of hydrogen concentration and the divergence of the concentration field, the formula can accurately calculate the diffusion speed and direction of hydrogen, thereby determining the optimal emptying power. At the same time, the formula also takes into account environmental parameters such as air density , ambient temperature , gas constant and hydrogen molar mass , so that the calculation results are more consistent with the actual physical scene. Introducing the efficiency coefficient This optimizes energy efficiency and avoids unnecessary energy consumption. This optimal emptying power calculation method, based on a scientific formula, can dynamically adjust the emptying power according to the actual leakage situation, improving emptying efficiency and saving energy. It also ensures that leaked hydrogen can be removed in a timely and effective manner, reducing safety risks.

[0047] For example, the traditional technical solution has the following technical problems: In the emergency treatment of hydrogen leakage, response time is a key factor. A response time that is too long will lead to a further increase in hydrogen concentration, increasing safety risks; while a response time that is too short may lead to overly radical emergency measures, resulting in a waste of resources. Existing emergency treatment systems are often unable to accurately determine a reasonable response time, resulting in unsatisfactory treatment effects. Based on this, the response time of the emergency treatment module is Determined by the following formula: ; in, is the safety factor; is the volume of space; is the maximum hydrogen concentration; is the optimal emptying power; For the Characteristic parameters of level leakage; is the corresponding weight coefficient, and satisfies .

[0048] It is worth mentioning that: this embodiment proposes the response time of the emergency processing module Determined by the following formula: in, is the safety factor; is the volume of space; is the maximum hydrogen concentration; The optimal emptying power calculated in claim 6; For the Characteristic parameters of level leakage; is the corresponding weight coefficient, and satisfies .

[0049] middle, The safety factor is a coefficient greater than 1 set to deal with uncertain factors. It is used to improve the reliability and safety of emergency response. Different application scenarios can set different safety factor values ​​according to the risk level. The spatial volume is the size of the detection area. A larger space means more time is needed to reduce the hydrogen concentration and implement emergency measures.

[0050] is the maximum hydrogen concentration, which reflects the severity of a hydrogen leak. The higher the concentration, the greater the potential danger, and the more rapid the emergency response required. The product of these three items represents the baseline risk after comprehensively considering safety redundancy, spatial scale, and leak severity, and is an important basic parameter for calculating response time.

[0051] Emptying power term: is the optimal emptying power calculated in claim 6, which represents the effective emptying capacity that the system can achieve. When calculating the response time, the basic risk amount is divided by the optimal emptying power, that is, , represents the theoretical time required to reduce the hydrogen concentration to a safe level or complete the corresponding emergency response, given the current emptying capacity. This calculation reflects the relationship between emptying capacity and emergency response requirements. A greater emptying power results in a shorter theoretical response time, and vice versa. This parameter closely links the response time calculation to the actual emptying operation.

[0052] Graded Response Items: Used to implement a hierarchical response mechanism, where For the The characteristic parameters of each level of leakage (level one, level two, level three) can be set according to the actual leakage situation, such as quantitative indicators including leakage speed, impact range, etc. Different levels of leakage have different characteristic parameter values. is the corresponding weight coefficient, and satisfies The weight coefficient is assigned based on the risk and importance of different levels of leakage, and is used to adjust the impact of each level of leakage on the response time. For example, level 3 leakage has the highest risk and can be assigned a larger weight coefficient. The basic response time is adjusted according to the leakage level, so that different levels of leakage correspond to different response time adjustment multiples, realizing a graded and flexible response for emergency treatment.

[0053] This formula establishes a scientific emergency response module response time calculation model by comprehensively considering multiple factors such as safety factor, space volume, maximum hydrogen concentration, emptying power and leakage level. It accurately reflects the appropriate time to activate the emergency response module in different leak scenarios, ensuring that emergency measures are neither premature, resulting in wasted resources, nor late, resulting in increased safety risks. Working in conjunction with other modules in the system, it makes the entire hydrogen leak emergency response process more accurate and efficient, significantly improving adaptability and effectiveness compared to traditional fixed response times or simple estimation methods.

[0054] The technical effects achieved by the above solution include: the formula of this embodiment establishes a functional relationship between the response time and multiple parameters, including the safety factor , spatial volume , maximum hydrogen concentration and optimal emptying power By comprehensively considering these parameters, the formula can accurately calculate the reasonable response time. At the same time, the formula also uses the leakage level characteristic parameters and weight coefficient This achieves a hierarchical response, with different response times corresponding to different leak levels, making emergency handling more flexible and effective. This, combined with the drain power formula in claim 6, forms a linked calculation model, further optimizing the overall system's operating efficiency. This scientific response time calculation method ensures that the emergency response module initiates appropriate emergency measures in the shortest possible time, improving processing efficiency and reducing safety risks.

[0055] For example, the traditional technical solution has the following technical problems: in the emergency treatment of hydrogen leaks, different levels of leaks require different emergency measures. If the emergency measures are inappropriate, it may lead to poor treatment results and even increase safety risks. Existing emergency treatment systems often lack a graded response mechanism. Regardless of the level of leakage, the same emergency measures are taken, which cannot meet actual needs. Based on this, the emergency treatment module includes an audible and visual alarm unit, a fire sprinkler unit and a personnel evacuation guidance unit; in the event of a level 1 leak, only the audible and visual alarm unit is activated; in the event of a level 2 leak, the audible and visual alarm unit and the fire sprinkler unit are activated; in the event of a level 3 leak, the audible and visual alarm unit, the fire sprinkler unit and the personnel evacuation guidance unit are activated.

[0056] It's worth noting that this embodiment refines the emergency response module of the previous embodiment, featuring an audible and visual alarm unit, a fire sprinkler unit, and a personnel evacuation guidance unit. In the event of a Level 1 leak, only the audible and visual alarm unit is activated; in the event of a Level 2 leak, both the audible and visual alarm unit and the fire sprinkler unit are activated; in the event of a Level 3 leak, all three units are activated.

[0057] The technical effects achieved by the above scheme include: the technical solution of this embodiment realizes precise emergency response by setting up a hierarchical response mechanism and activating different emergency units according to the leakage level. For a level 1 leakage, only the sound and light alarm unit is activated to alert the staff and avoid overreaction; for a level 2 leakage, the sound and light alarm unit and the fire sprinkler unit are activated, and measures are taken to control the hydrogen concentration at the same time as the alarm; for a level 3 leakage, all emergency units are activated, including the personnel evacuation and guidance unit, to ensure the safety of personnel. This hierarchical response mechanism improves the pertinence and effectiveness of emergency response and can maximize the safety of personnel and equipment in the event of leakage of different degrees.

[0058] Traditional solutions present the following technical challenges: The reliability of the communication module is crucial in hydrogen leak detection and treatment systems. If a communication failure occurs, data transmission between modules will be disrupted, and the entire system will not function properly, potentially leading to serious safety incidents. Existing communication systems often rely on a single communication method, and if that method fails, the system loses communication capabilities. Therefore, the communication module utilizes a combination of wireless and wired communication technologies for data transmission, automatically switching to wired communication if wireless communication fails.

[0059] It is worth mentioning that: this embodiment further limits the communication module in the above embodiment, which is characterized in that the module adopts a combination of wireless communication technology and wired communication technology to transmit data, and automatically switches to wired communication when wireless communication fails.

[0060] The technical effects achieved by the above solution include: The technical solution of this embodiment significantly improves the reliability of the communication module by combining wireless and wired communication and providing an automatic switching mechanism. Under normal circumstances, the system can select the appropriate communication method for data transmission based on actual conditions; if wireless communication fails, the system can automatically switch to wired communication to ensure communication continuity. This dual communication guarantee mechanism reduces the risk of system failure due to communication failures, improves the stability and reliability of the entire system, and provides a solid communication foundation for hydrogen leak detection and treatment.

[0061] For example, traditional technical solutions have the following technical problems: In the emergency treatment of hydrogen leaks, a scientific and reasonable treatment process is required to ensure the effective connection and efficient execution of each link. Existing emergency treatment methods often lack systematicity and standardization, and the coordination between various links is poor, resulting in low treatment efficiency and increased safety risks. Based on this, this embodiment provides an emergency treatment method based on any of the above-mentioned high-efficiency hydrogen leak explosion detectors and rapid emptying linkage systems, including the following steps: The hydrogen concentration detection module collects the hydrogen concentration data in the environment around the hydrogen production equipment in real time and transmits the data to the data processing module; After receiving the data, the data processing module analyzes and processes the data based on the preset algorithm to determine whether hydrogen leakage occurs and the leakage level; If hydrogen leakage is determined to have occurred, the data processing module controls the rapid emptying device to perform the corresponding emptying operation according to the leakage level; After the rapid emptying device performs the emptying operation, the emergency treatment module initiates corresponding emergency treatment measures according to the leakage level.

[0062] It is worth mentioning that: this embodiment proposes an emergency treatment method based on the high-efficiency hydrogen leakage explosion detector and the rapid emptying linkage system described in any of the above embodiments, which is characterized by including the following steps: the hydrogen concentration detection module collects the hydrogen concentration data in the environment surrounding the hydrogen production equipment in real time, and transmits the data to the data processing module; after receiving the data, the data processing module analyzes and processes the data based on a preset algorithm to determine whether a hydrogen leakage has occurred and the leakage level; if it is determined that a hydrogen leakage has occurred, the data processing module controls the rapid emptying device to perform the corresponding emptying operation according to the leakage level; after the rapid emptying device performs the emptying operation, the emergency treatment module initiates the corresponding emergency treatment measures according to the leakage level.

[0063] The technical effects achieved by the above scheme include: the emergency treatment method of this embodiment is based on the linkage system described in the above embodiment, forming a complete, closed-loop processing flow. From the collection, analysis and judgment of hydrogen concentration data to emptying operations and emergency treatment, each link is closely connected and coordinated. This systematic treatment method improves the efficiency and accuracy of emergency treatment, ensuring that when a hydrogen leak occurs, measures can be taken quickly and effectively to reduce safety risks. At the same time, this method cooperates with the system claims of the above embodiment to form a complete technical solution, further enhancing the creativity and practicality of the entire system.
