[0048] As an optional embodiment, the electrolysis tank 102 further comprises a water-oxygen separation device, wherein the plurality of electrolytic cells are connected with the water-oxygen separation device, and the water-oxygen separation device is used for separating hydrogen and oxygen generated by electrolysis.

[0049] In this embodiment, it is explained that the electrolysis tank 102 further comprises a water-oxygen separation device. The water-oxygen separation device is a device used for separating hydrogen and oxygen in the process of electrolytic hydrogen production, which separates hydrogen and oxygen based on the physical or chemical properties of the hydrogen-oxygen mixed gas generated by the electrolytic cell to provide hydrogen and oxygen with higher purity. The plurality of electrolytic cells are connected with the water-oxygen separation device, which means that the hydrogen-oxygen mixed gas generated by the electrolytic cell will be directly transported to the water-oxygen separation device for separation. This direct connection design ensures the efficiency and continuity of the gas from generation to separation process, reducing the loss or pollution that may occur during transmission.

[0050] In this embodiment, the structure of the electrolysis box 102 is further optimized, not only containing multiple electrolytic cells for water electrolysis, but also integrating a set of water-oxygen separation equipment. The electrolytic cells decompose water into hydrogen and oxygen through electrolysis, and the generated hydrogen-oxygen mixed gas directly enters the water-oxygen separation equipment, which separates the gas according to its physical or chemical properties (such as boiling point, adsorption) to obtain high-purity hydrogen and oxygen.

[0051] As an optional embodiment, the control box 104 further comprises a global data storage device, wherein the programmable logic controller is connected with the global data storage device, and the global data storage device is used to store global data in the hydrogen production process.

[0052] In this embodiment, it is illustrated that the control box 104 further comprises a global data storage device. The global data storage device is a device used for long-term storage and management of all data generated during the operation of the hydrogen production equipment 100, including but not limited to current, voltage, temperature, pressure, flow, electrolytic cell working state, etc. The global data storage device can be a dedicated database server, or a device with large capacity storage function, such as NAS (Network Attached Storage) or SAN (Storage Area Network).

[0053] The programmable logic controller (PLC) is connected with the global data storage device, which means that all the hydrogen production process data collected by the PLC will be sent and stored in the global data storage device in real time. This design ensures the integrity and timeliness of the data, providing a basis for subsequent data analysis and equipment management.

[0054] The global data storage device is added in the control box 104, forming a close data collection and storage relationship with the PLC. The global data storage device can store all data in the hydrogen production process, including real-time running parameters, historical running records, fault and alarm information, etc. By storing these data for a long time, detailed information basis can be provided for the analysis of the running state of the equipment, fault diagnosis and prediction, and performance optimization.

[0055] As an optional embodiment, the control box 104 further comprises a rotating device, wherein the rotating device comprises a fan, and the fan is used to cool the control box 104.

[0056] In this embodiment, it is illustrated that the control box 104 further comprises a rotating device. Rotating devices generally refer to mechanical devices that need to rotate during operation, including various types of pumps, fans, mixers, etc. In the hydrogen production system, the rotating device mainly refers to the fan used for air circulation, gas delivery or cooling and heat dissipation.

[0057] Among them, the fan is a device for air circulation or airflow generation, which can force air flow to achieve heat exchange and cool the equipment. In the control box 104, the fan is mainly used to reduce the heat generated by the equipment during operation, and to maintain the temperature in the box within a safe and suitable range.

[0058] The fan is integrated into the control box 104 as a rotating device designed to control the heat dissipation inside the box 104. Since the PLC, server and other electronic devices contained in the control box 104 generate a large amount of heat during operation, if not effectively cooled, it may cause overheating of the equipment, affecting the stability and service life of the operation. By deploying a fan in the control box 104, hot air can be forced out and cold air can be introduced for circulation, thereby maintaining the stability of the temperature inside the box and providing a good working environment for the equipment.

[0059] As an optional embodiment, the control box 104 further comprises a frequency conversion cabinet, wherein the frequency conversion cabinet is connected with the rotating device, and the frequency conversion cabinet is used to control the rotating parameters of the rotating device.

[0060] In this embodiment, it is illustrated that the control box 104 further comprises a frequency conversion cabinet. The frequency conversion cabinet is a device specially used to control the speed and torque of the motor, which adjusts the running speed by changing the frequency of the power supply to the motor. The frequency conversion cabinet integrates frequency converters, circuit protection devices and control circuits, etc., which can automatically adjust the speed of the motor according to actual needs, achieve energy saving, improve equipment efficiency and prolong equipment life.

[0061] The frequency conversion cabinet is connected with the rotating device, which means that the frequency conversion cabinet will directly control the speed and torque of these devices. For example, in the control box 104, the fan is used for heat dissipation, and the frequency conversion cabinet can adjust the speed of the fan according to real-time temperature data, so as to accurately control the heat dissipation effect and avoid excessive heat dissipation or insufficient heat dissipation.

[0062] In this embodiment, the frequency conversion cabinet is integrated into the control box 104 and connected with the rotating devices such as the fan, which is used to dynamically adjust the speed and operating parameters of these devices. Through the temperature, pressure and other sensor data collected by the PLC, the frequency conversion cabinet can intelligently adjust the speed of the fan to ensure that the temperature inside the control box 104 is maintained at an optimal level. At the same time, the use of the frequency converter can also reduce energy consumption and improve the overall energy efficiency of the system.

[0063] As an optional embodiment, the edge control device 200 further comprises a firewall device, wherein the hydrogen production device 100 is connected with the firewall device through the programmable logic controller, and the firewall device is connected with the edge computing gateway 202.

[0064] In this embodiment, it is illustrated that the edge control device 200 also includes a firewall device. The firewall device is a network security device that monitors and controls data communication between networks to prevent unauthorized access while allowing legitimate communication. The firewall checks information such as the source address, target address, port number and protocol type of the data packet to decide whether to allow the data packet to pass through, and is the first line of defense for network security.

[0065] In the hydrogen production device 100, the connection relationship of the edge control device 200 is as follows: first, various sensors and actuators in the hydrogen production device 100 collect and send data through the PLC, which is the core of the control system, preprocesses the data and controls the device in real time according to the preset control logic. Subsequently, the PLC transmits the data to the firewall device through a secure network connection. The firewall device, as the protector of the network, checks the data packets sent from the PLC to ensure that only legitimate data can pass through and reach the edge computing gateway 202. Finally, the edge computing gateway 202 collects and processes the data filtered by the firewall, executes more advanced data analysis and device control strategies, and at the same time, encrypts and formats the data that needs to be uploaded to the central server to ensure safe transmission and efficient processing of the data.

[0066] In this embodiment, the deployment of the firewall device is the key to the network security of the hydrogen production system. The firewall device is located between the programmable logic controller and the edge computing gateway 202, ensuring the security and integrity of the data during transmission. Through the firewall device, external malicious attacks and internal data leaks can be prevented, and at the same time, the firewall can also filter and optimize the passing data to improve the efficiency of data transmission.

[0067] As an optional embodiment, the server device 204 further includes a virtualization platform and a computing cluster of a distributed computing framework, wherein the virtualization platform is connected with the computing cluster.

[0068] In this embodiment, it is illustrated that the server device 204 further comprises a virtualization platform and a computing cluster of a distributed computing framework. The virtualization platform is a technology that enables server resources (such as processors, memory, storage, network) to be shared in multiple virtual environments. It creates multiple virtual machines (VMs) by running virtualization software such as virtual machine software (VMware), kernel-based virtual machine (KVM), Hyper-V (Hyper-V), etc. on a physical server, each of which can independently run an operating system and application, as if they were running on an independent physical server. The virtualization platform improves the utilization of server resources, simplifies the management of servers, and reduces hardware costs. The distributed computing framework is a software architecture that can handle large-scale data sets, which distributes data processing tasks to multiple computing nodes for parallel execution to improve computing performance and data processing speed. Common distributed computing frameworks include Apache Hadoop, Apache Spark, etc., which provide distributed storage and computing capabilities for data, supporting big data analysis and machine learning. The computing cluster is a group of computers connected by a network to perform computing tasks together. Each computer (node) in the cluster can perform part of the computing task, and the results are finally aggregated to achieve large-scale data processing and high-performance computing. The computing cluster is the basis for implementing the computing capabilities of the distributed computing framework, and can provide linearly scalable computing resources.

[0069] In the server device 204, the virtualization platform is closely connected with the computing cluster of the distributed computing framework. The virtualization platform is responsible for creating and managing virtual machines, while the computing cluster runs distributed computing frameworks such as Hadoop or Spark on these virtual machines. The virtualization platform provides independent computing and storage resources for each virtual machine through virtualization technology, ensuring that each node in the computing cluster can run efficiently. At the same time, the virtualization platform can dynamically allocate resources according to the load of the computing cluster, optimizing the use of resources.

[0070] In this embodiment, the server device 204 uses a combination of virtualization platforms and computing clusters to provide powerful computing and storage capabilities for the monitoring system. The virtualization platform creates multiple virtual machines, each of which runs a node of the distributed computing framework. The data uploaded by the edge computing gateway 202 is first stored in the virtualized storage resources, and then the computing cluster distributes data processing tasks to each node for parallel execution, such as big data analysis, machine learning model training, etc. This design not only enables the processing of large-scale data sets and improves data processing speed, but also enables flexible allocation and management of resources, reduces hardware costs, and improves the utilization and stability of the server device 204.

[0071] As an optional embodiment, the programmable logic controller is configured with a security module.

[0072] In this embodiment, it is illustrated that the programmable logic controller is configured with a safety module, which is a specially designed hardware component in the programmable logic controller (PLC) for improving the safety of industrial control systems. It can execute safety-related control logic, such as emergency shutdown, fault detection and diagnosis, etc., to ensure that industrial equipment can safely stop running or enter a predetermined safe state when an abnormal situation occurs.

[0073] In the hydrogen production equipment 100, the programmable logic controller (PLC) is configured with a safety module, which means that the PLC integrates functions specifically for safety control. The safety module is closely integrated with the control logic of the PLC and can monitor multiple safety-critical parameters in real time during the hydrogen production process, such as temperature, pressure, gas concentration, etc. When any abnormal situation that may threaten the safe operation of the equipment is detected, the safety module will immediately start the corresponding safety program, such as emergency shutdown or closing the hydrogen pipeline, to prevent accidents and ensure the safety of personnel and equipment.

[0074] As an optional embodiment, the hydrogen production equipment 100 and the edge control equipment 200 communicate through a predetermined network technology, which includes any one of the following: industrial Ethernet, fieldbus technology.

[0075] In this embodiment, it is illustrated that the hydrogen production equipment 100 and the edge control equipment 200 communicate through a predetermined network technology.

[0076] Among them, industrial Ethernet is a network technology used in the field of industrial automation, which is based on standard Ethernet technology, but optimized in terms of reliability and real-time performance. Standard Ethernet hardware (such as network switches, network cables, connectors, etc.) and devices are used. Industrial Ethernet can provide high-speed and stable network connections, enabling the hydrogen production equipment 100 and the edge control equipment 200 to quickly and accurately transmit data. Fieldbus technology is a network communication protocol used in automated production sites, which supports direct data exchange between the hydrogen production equipment 100 and the edge control equipment 200 without the intervention of a central computer. Fieldbus technology can reduce communication delay and improve the reliability and security of data transmission. Common fieldbus technologies include Process Field Bus (PROFIBUS), Ethernet Control Automation Bus (EtherCAT), etc.

[0077] In the monitoring system, the hydrogen production equipment 100 and the edge control equipment 200 communicate by using industrial Ethernet or fieldbus technology, which means that the system uses high-speed and reliable network technology to ensure data transmission.

Specifically, the sensors and actuators in the hydrogen production equipment 100 are connected to the PLC of the edge control equipment 200 through industrial Ethernet or fieldbus technology, and the PLC can collect and process these data in real time, and perform preliminary control logic such as temperature and pressure regulation. At the same time, the PLC uploads the data to the edge computing gateway 202 through industrial Ethernet or fieldbus technology, and the edge computing gateway 202 performs more complex data analysis and processing.
