Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen energy digital management, and in particular to a hydrogen energy management system and a control method thereof. Background Art

[0002] As a form of energy, hydrogen energy has always faced challenges in terms of its acquisition, storage, and use management. This has necessitated the emergence of a smart hydrogen energy production and operation full-process management and control platform. For example, there is a lack of data exchange between hydrogen production / charging devices, hydrogen storage devices, and hydrogen consumption devices, making it impossible to accurately display the hydrogen content stored in the hydrogen storage device. When using a hydrogen energy device, users also need to know information such as the time required to fill the hydrogen storage device, the amount of hydrogen required, how long the hydrogen consumption device can last, and the remaining hydrogen content in the hydrogen storage device after use.

[0003] Furthermore, hydrogen storage devices used for a long time are prone to wear and tear or accidental gas release, resulting in a discrepancy between the actual hydrogen content stored in the device and the information recorded in the read / write memory, which will adversely affect both the charging and use processes. Therefore, a new hydrogen energy management system and control method is needed to achieve visual, real-time monitoring and precise control of each link, including hydrogen production, charging, storage, and use. It can also calibrate hydrogen storage devices, improve hydrogen energy management efficiency, and thus promote cost reduction and efficiency improvement in the industry. Summary of the Invention

[0022] Preferably, the step of obtaining the detected consumption of the hydrogen consumption device in real time includes:

[0023] The detection consumption rate C of the hydrogen-using device in the current hydrogen-using cycle is calculated according to C=K*I*N, and the detection consumption amount of the hydrogen storage device is calculated according to the detection consumption rate C and the detection consumption time of the current hydrogen-using cycle;

[0024] Wherein, K is the Faraday constant, I is the sum of the load current, heater current and circuit static fixed current of the hydrogen using device, and N is the number of cells in the hydrogen fuel cell stack.

The first read-write module writes the current hydrogen content and the number of hydrogen charging times of the hydrogen storage device into the read / write memory, and the hydrogen production / charging device feeds back the hydrogen charging increment, current hydrogen content, digital identity and number of hydrogen charging times of the hydrogen storage device to the server.

[0037] After adopting the above technical solution, compared with the existing technology, it has the following beneficial effects: the data of the hydrogen energy device in various links such as hydrogen production, hydrogen filling, hydrogen storage and hydrogen use are connected and visual management is carried out.

[0050] like Figures 1 to 2 As shown, the present invention discloses a control method for a hydrogen energy management system, wherein the management system includes a hydrogen storage device, a hydrogen production / charging device, a server and a user end, and the control method includes the following steps:

[0051] S110 , in response to a hydrogen charging instruction to the hydrogen production / charging device, controlling the hydrogen production / charging device to enter a hydrogen charging mode, so that the hydrogen production / charging device charges the hydrogen storage device with hydrogen.

[0052] Specifically, by way of example and not limitation, the hydrogen storage device may be a hydrogen storage bottle, a hydrogen energy rod, a solid-state hydrogen battery or other equipment for storing hydrogen; the hydrogen production / charging device may be an integrated hydrogen production and charging device. When the hydrogen production / charging device is connected to the hydrogen storage device through a hydrogen charging pipeline, the hydrogen production / charging device can prepare hydrogen and charge the hydrogen into the hydrogen storage device.

[0053] It is understood that the hydrogen charging instruction to the hydrogen production / charging device can be generated by a user directly operating the hydrogen production / charging device after connecting the hydrogen storage device to the hydrogen production / charging device, or it can be generated by a user remotely operating the hydrogen production / charging device through a server or user terminal. In response to the hydrogen charging instruction, the hydrogen production / charging device is controlled to enter a hydrogen charging mode. Specifically, the electrolysis unit of the hydrogen production / charging device is controlled to produce hydrogen, and the hydrogen charging valve of the hydrogen charging pipeline connected to the hydrogen production / charging device is controlled to open, so that the hydrogen production / charging device begins to produce hydrogen and charge the hydrogen into the hydrogen storage device.

[0054] S120 , reading the read / write memory of the hydrogen storage device to obtain the initial hydrogen content of the hydrogen storage device, and displaying the initial hydrogen content on the first display module of the hydrogen production / charging device.

[0055] Specifically, in actual applications, the hydrogen storage device can be a plurality of replaceable hydrogen storage devices. Therefore, a read / write memory is provided on each hydrogen storage device. The read / write memory is a storage device that can record data related to the hydrogen storage device. In this embodiment, any read / write memory contains the digital identity of the hydrogen storage device where the read / write memory is located, as well as information such as the hydrogen content, the number of hydrogen charging times, the usage time, and the service life. Specifically, the digital identity includes the device number independently corresponding to the hydrogen storage device, the hydrogen content is the ratio of the volume of hydrogen stored in the hydrogen storage device to the maximum volume of the hydrogen storage device, the number of hydrogen charging times is the number of times the hydrogen storage device has been charged with hydrogen via the hydrogen production / charging device, the usage time is the time since the hydrogen storage device was shipped from the factory, and the service life is the remaining time that the hydrogen storage device can be safely used or the remaining number of hydrogen charging times.

[0056] A first read / write module provided on the hydrogen production / charging device reads a read / write memory of the hydrogen storage device to which the hydrogen production / charging device is currently connected, thereby obtaining the digital identity and initial hydrogen content of the hydrogen storage device. It is understood that the initial hydrogen content refers to the hydrogen content of the hydrogen storage device at the moment the management system enters the hydrogen charging mode. The initial hydrogen content of the hydrogen storage device is displayed on a first display module, which may be, for example, an external display screen provided on the hydrogen production / charging device.

[0057] S130, obtaining the hydrogen charging increment and hydrogen charging time of the hydrogen storage device in real time, obtaining the current hydrogen content of the hydrogen storage device and writing it into the read / write memory every time the hydrogen charging increment of the hydrogen storage device exceeds the hydrogen charging increment threshold, and reading the read / write memory to obtain the current hydrogen content of the hydrogen storage device and displaying it on the first display module of the hydrogen making / charging device every time the hydrogen charging time of the hydrogen storage device exceeds the hydrogen charging time threshold.

[0058] Specifically, the hydrogen charging increment refers to the ratio of the volume of hydrogen charged by the hydrogen production / charging device to the maximum volume of the hydrogen storage device, and the hydrogen charging time refers to the duration over which the hydrogen production / charging device charges the hydrogen storage device. In this embodiment, a hydrogen charging increment threshold and a hydrogen charging time threshold may be pre-stored in the hydrogen production / charging device, and the hydrogen charging increment and the hydrogen charging increment threshold, and the hydrogen charging time and the hydrogen charging time threshold, respectively, may be compared.

[0059] Each time the hydrogen charging increment exceeds a hydrogen charging increment threshold, the hydrogen production / charging device may calculate the current hydrogen content of the hydrogen storage device based on the initial hydrogen content of the hydrogen storage device and the hydrogen charging increment, and write the calculated hydrogen content into the read / write memory via the first read / write module, thereby updating the hydrogen content currently stored in the read / write memory. For example, assuming the hydrogen charging increment threshold is 2%, the hydrogen charging increment increases as the hydrogen production / charging device charges the hydrogen storage device. Each time the hydrogen charging increment exceeds a 2% threshold, the current hydrogen content of the hydrogen storage device is obtained and written into the read / write memory. In other words, the current hydrogen content currently stored in the read / write memory is updated each time the hydrogen charging increment exceeds a 2% threshold.

[0060] At each hydrogen charging time threshold, the first read / write module reads the read / write memory and displays the current hydrogen content written in the read / write memory on the first display module. For example, assuming the hydrogen charging time threshold is 10 seconds, the hydrogen charging time increases as the hydrogen production / charging device charges the hydrogen storage device. At each 10-second interval of the hydrogen charging time, the current hydrogen content written in the read / write memory is read and displayed on the first display module. In other words, the current hydrogen content displayed on the first display module is updated at each 10-second interval of the hydrogen charging time.

[0061] Specifically, such as Figure 2 As shown, in order to update the current hydrogen content displayed on the first display module according to the hydrogen filling time threshold, a repeating timer can be set on the hydrogen production / charging device, and the single timing duration of the timer is the hydrogen filling time threshold. After the hydrogen production / charging device enters the hydrogen filling mode, the timer starts timing when the hydrogen production / charging device fills the hydrogen storage device with hydrogen. The hydrogen production / charging device detects trigger events, and any trigger event corresponds to the following Figure 2 The control method is implemented by following the process shown in the figure. Each time the timer completes a count, the first read / write module reads the read / write memory and displays the current hydrogen content written in the read / write memory on the first display module. After each display update, the trigger event is cleared and the timer restarts the next count until the hydrogen charging increment reaches the preset threshold, exiting the hydrogen charging mode.

[0062] Furthermore, as a supplement to step S130, to address the risk of a possible failure of the first read / write module, a read / write repetition count threshold may be pre-stored in the hydrogen production / charging device. When a write operation to or a read operation from the read / write memory fails, the write operation to or the read operation from the read / write memory is repeatedly triggered and the number of repetitions is calculated. When the number of repetitions reaches the read / write repetition count threshold, the hydrogen production / charging device stops charging the hydrogen storage device and exits the hydrogen charging mode. This prevents the failure of the first read / write module from accurately displaying the current hydrogen content of the hydrogen storage device, which could hinder subsequent use of the hydrogen storage device.

[0063] S140: When the hydrogen charging increment of the hydrogen storage device reaches a preset hydrogen charging threshold, the control / charging device stops charging hydrogen into the hydrogen storage device, the number of hydrogen charging times of the hydrogen storage device increases by one, and after obtaining the current hydrogen content and the number of hydrogen charging times of the hydrogen storage device and writing them into the read / write memory, the hydrogen charging increment, current hydrogen content, digital identity and number of hydrogen charging times of the hydrogen storage device are fed back to the server, and the control / charging device exits the hydrogen charging mode.

[0064] Specifically, the preset hydrogen filling threshold represents the ratio of the volume of hydrogen to be filled into the hydrogen storage device when entering the hydrogen filling mode to the maximum volume of the hydrogen storage device, and can be determined in the hydrogen filling instruction for the hydrogen production / charging device. For example, when the initial hydrogen content of the hydrogen storage device is 20%, and the hydrogen filling instruction for the hydrogen production / charging device instructs the hydrogen storage device to be filled to a hydrogen content of 100%, the preset hydrogen filling threshold can be determined to be 80%. Therefore, when the hydrogen filling increment of the hydrogen storage device reaches 80%, the hydrogen production / charging device stops filling the hydrogen storage device with hydrogen, and the number of hydrogen fillings written in the read / write memory is recorded as an increase, and the current hydrogen content of the hydrogen storage device is obtained as 100%. The first read / write module writes the current hydrogen content of 100% and the updated number of hydrogen fillings into the read / write memory, at which point the control and management system exits the hydrogen filling mode. Furthermore, the hydrogen production / charging device feeds back the hydrogen storage device's hydrogen charge increment, current hydrogen content, digital identity, and number of hydrogen charges to the server. Because the digital identity corresponds one-to-one with each hydrogen storage device, the server accurately records the current hydrogen content and number of hydrogen charges for each hydrogen storage device. Furthermore, the server can send the recorded current hydrogen content and number of hydrogen charges for any hydrogen storage device to the user terminal for display, allowing the user to obtain the hydrogen storage status of each hydrogen storage device on the user terminal and achieve data interoperability.

[0065] In an optional embodiment, the following steps are also included:

[0066] In response to a calibration hydrogen charging instruction for the hydrogen production / charging device, controlling the hydrogen production / charging device to enter a calibration hydrogen charging mode, so that the hydrogen production / charging device charges the hydrogen storage device with hydrogen;

[0067] Acquire the current hydrogen content of the hydrogen storage device in real time, and when the current hydrogen content reaches a safe hydrogen content, control the control / hydrogen charging device to continue charging hydrogen into the hydrogen storage device;

[0068] The detection pressure in the hydrogen storage device is obtained in real time. When the detection pressure is greater than the calibration pressure threshold, the hydrogen production / charging device stops charging hydrogen into the hydrogen storage device, and the number of hydrogen charges of the hydrogen storage device increases by one. After the full content is used as the current hydrogen content of the hydrogen storage device and the number of hydrogen charges are written into the read / write memory, the digital identity of the hydrogen storage device, the current hydrogen content and the number of hydrogen charges are fed back to the server, and the hydrogen production / charging device is controlled to exit the calibration hydrogen charging mode.

[0069] Specifically, during the use of the hydrogen storage device, the hydrogen storage device may be accidentally deflated, or the read / write memory may fail to update during hydrogen use. This will cause the current hydrogen content written in the read / write memory to deviate from the actual hydrogen content stored in the hydrogen storage device. Therefore, the hydrogen storage device needs to be calibrated and filled with hydrogen.

[0070] Typically, for safety reasons, the hydrogen charging instructions for the hydrogen production / charging device instruct the hydrogen storage device to charge to a hydrogen content of 95%, i.e., the safety hydrogen content is set at 95%. This means that when the current hydrogen content of the hydrogen storage device reaches 95%, the hydrogen production / charging device stops charging the hydrogen storage device, and the management system exits the hydrogen charging mode. In the calibration hydrogen charging mode of the present invention, however, the detection pressure within the hydrogen storage device is used as the basis for stopping hydrogen charging. Even after the current hydrogen content reaches 95%, hydrogen charging continues until the detection pressure exceeds a preset calibration pressure threshold, thereby ensuring that the actual hydrogen content stored in the hydrogen storage device is consistent with the current hydrogen content written in the read / write memory.

[0071] It is understood that the calibration hydrogen charging instruction for the hydrogen production / charging device can be generated by a user directly operating the hydrogen production / charging device after connecting the hydrogen storage device to the hydrogen production / charging device, or it can be generated by a user remotely operating the hydrogen production / charging device through a server or user terminal. In response to the calibration hydrogen charging instruction, the hydrogen production / charging device is controlled to enter a calibration hydrogen charging mode. Specifically, the electrolysis unit of the hydrogen production / charging device is controlled to produce hydrogen, and the hydrogen charging valve of the hydrogen charging pipeline connected to the hydrogen production / charging device is controlled to open, so that the hydrogen production / charging device begins to produce hydrogen and charge the hydrogen into the hydrogen storage device.

[0072] Specifically, a sensing unit within the hydrogen storage device acquires a detected air pressure within the hydrogen storage device in real time. When the detected air pressure is greater than a calibration pressure threshold, the hydrogen content actually stored in the hydrogen storage device is determined to be full, i.e., 100%. The hydrogen production / charging device is controlled to stop charging the hydrogen storage device, the number of hydrogen charges written in the read / write memory is incremented by one, the first read / write module writes 100% as the current hydrogen content into the read / write memory, and the updated number of hydrogen charges is written into the read / write memory. The digital identity of the hydrogen storage device, the current hydrogen content, and the number of hydrogen charges are fed back to the server. At this point, the hydrogen production / charging device is controlled to exit the calibration hydrogen charging mode.

[0073] Preferably, the method further comprises the following steps:

[0074] The server is used to monitor the usage time of the hydrogen storage device in real time. At each calibration period, the server sends a calibration reminder signal to the user end, and the calibration reminder signal includes the digital identity of the hydrogen storage device.

[0075] Specifically, the server stores the usage time of the hydrogen storage device. For each calibration period between each hydrogen storage device usage period, the server sends a calibration reminder signal to the user terminal. The calibration reminder signal indicates that the hydrogen storage device should be charged in the calibration charging mode. For example, for each hydrogen storage device, the server sends a calibration reminder signal with the digital identity of the hydrogen storage device to the user terminal every three months of usage.

[0076] Preferably, the calibration period of the hydrogen storage device decreases as the number of hydrogen charging times increases.

[0077] It is understandable that the longer a hydrogen storage device is used, the more likely it is that there will be a problem of deviation between the current hydrogen content written in the read / write memory and the actual stored hydrogen content. Therefore, the calibration period of any hydrogen storage device is determined according to the number of times it has been charged with hydrogen, so that the more times a hydrogen storage device has been charged with hydrogen, the shorter its calibration period is, and the higher the frequency of sending calibration prompt signals for the hydrogen storage device.

[0078] In an optional embodiment, as Figures 3 and 4 As shown, the management system also includes a hydrogen device, and the control method further includes the following steps:

[0079] S210 , in response to a start-up instruction for a hydrogen fuel cell stack in a hydrogen-using device, controlling the hydrogen-using device to enter a hydrogen-using mode, and consuming the hydrogen stored in the hydrogen storage device.

[0080] By way of example and not limitation, the hydrogen-using device may be a hydrogen fuel vehicle, a hydrogen emergency power supply, or the like, which converts hydrogen into electricity. It is understood that the startup instruction for the hydrogen fuel cell stack may be a user-generated startup instruction generated by directly operating the hydrogen-using device, or a user-generated startup instruction generated by remotely operating the hydrogen-using device through a server or user terminal. In response to the startup instruction, the control and management system enters a hydrogen-using mode, using the hydrogen device to consume the hydrogen stored in the hydrogen storage device.

[0081] S220. Obtain the specified consumption of the hydrogen-using device in the current hydrogen consumption cycle, and obtain the detected consumption of the hydrogen storage device in real time. When the detected consumption reaches the specified consumption, obtain the current hydrogen content of the hydrogen storage device and write it into the read / write memory, and then feed back the current hydrogen content and digital identity of the hydrogen storage device to the second display module and the server of the hydrogen-using device, enter the next hydrogen consumption cycle and repeat this step.

[0082] Specifically, the designated consumption required by the hydrogen-using device is determined in each hydrogen-using cycle, that is, the volume of hydrogen that the hydrogen-using device needs to consume in the current hydrogen-using cycle. The detected consumption of the hydrogen storage device is the volume of hydrogen reduced by the hydrogen storage device. Before the detected consumption reaches the designated consumption, the hydrogen-using device continues to consume hydrogen; when the detected consumption reaches the designated consumption, the second read-write module in the hydrogen-using device writes the current hydrogen content of the hydrogen storage device updated after the current hydrogen-using cycle into the read / write memory, and feeds back the updated current hydrogen content of the hydrogen storage device and its digital identity to the second display module of the hydrogen-using device and the server. The second display module can be an instrument on the hydrogen-using device; enter the next hydrogen-using cycle and repeat this step, that is, obtain the designated consumption and detected consumption of the next hydrogen-using cycle, and when the detected consumption reaches the designated consumption again, the second read-write module updates the current hydrogen content and writes it into the read / write memory.

[0083] S230. In response to a shutdown instruction for the hydrogen fuel cell stack, the hydrogen-using device stops consuming the hydrogen stored in the hydrogen storage device, obtains the current hydrogen content of the hydrogen storage device and writes it into a read / write memory, then feeds back the current hydrogen content and digital identity of the hydrogen storage device to the second display module and the server, and controls the hydrogen-using device to exit the hydrogen use mode.

[0084] Specifically, in hydrogen use mode, a user can directly operate the hydrogen-using device to generate a shutdown instruction for the hydrogen fuel cell stack, or the user can remotely operate the hydrogen-using device through a server or user terminal to generate a shutdown instruction for the hydrogen fuel cell stack. In response to the shutdown instruction, even if the detected consumption may not have reached the specified consumption, the hydrogen-using device stops consuming the hydrogen stored in the hydrogen storage device. The second read-write module writes the updated current hydrogen content of the hydrogen storage device to the read / write memory, and feeds back the updated current hydrogen content of the hydrogen storage device and its digital identity to the second display module of the hydrogen-using device and the server.

[0085] Preferably, the step of obtaining the detected consumption of the hydrogen-using device in real time includes:

[0086] The detection consumption rate C of the hydrogen-using device in the current hydrogen-using cycle is calculated according to C=K*I*N, and the detection consumption amount of the hydrogen storage device is calculated according to the detection consumption rate C and the detection consumption time of the current hydrogen-using cycle;

[0087] Wherein, K is the Faraday constant, I is the sum of the load current, heater current and static fixed current of the hydrogen device, and N is the number of cells in the hydrogen fuel cell stack.

[0088] Specifically, the unit of the detection consumption rate C is L / min. By multiplying the detection consumption rate by the detection consumption time of the current hydrogen consumption cycle, the detection consumption after different detection consumption times can be obtained in real time.

[0089] Preferably, if Figure 4 As shown, the following steps are also included:

[0090] When the operation of writing the current hydrogen content of the hydrogen storage device into the read / write memory fails, the current hydrogen content and digital identity of the hydrogen storage device at the end of the previous hydrogen use cycle are fed back to the second display module and the server.

[0091] It can be understood that when there is a fault in the second read-write module and the operation of writing to the read / write memory fails, the current hydrogen content and digital identity of the hydrogen storage device at the end of the previous hydrogen usage cycle are fed back to the second display module and the server, and wait until the end of the next hydrogen usage cycle to rewrite the read / write memory.

[0092] Preferably, if Figure 4 As shown, in response to the start-up instruction of the hydrogen fuel cell stack in the hydrogen-using device, the steps of controlling the management system to enter the hydrogen-using mode include:

[0093] In response to a start-up instruction to a controller of the hydrogen fuel cell stack, reading a read / write memory of the hydrogen storage device to obtain a current hydrogen content and a digital identity of the hydrogen storage device;

[0094] In response to a start-up instruction for the hydrogen fuel cell stack, the control management system enters a hydrogen use mode, and uses the hydrogen device to consume the hydrogen stored in the hydrogen storage device.

[0095] Specifically, after starting the controller of the hydrogen fuel cell stack, if no startup instruction for the hydrogen fuel cell stack is generated at this time, the control management system will not enter the hydrogen use mode. The second read-write module will only read the read / write memory to obtain the current hydrogen content and digital identity of the hydrogen storage device to display to the user.

[0096] In an optional embodiment, the following steps are also included:

[0097] The server is used to monitor the current hydrogen content of the hydrogen storage device in real time. When the current hydrogen content of the hydrogen storage device is lower than the hydrogen content threshold, the server is used to send a hydrogen charging prompt signal to the user end. The hydrogen charging prompt signal includes the current hydrogen content and digital identity of the hydrogen storage device.

[0098] Specifically, since the hydrogen production / charging device in hydrogen charging mode feeds the current hydrogen content of the hydrogen storage device to the server, and the hydrogen consumption device in hydrogen consumption mode feeds the current hydrogen content of the hydrogen storage device to the server, the server can monitor the current hydrogen content of any hydrogen storage device in real time. When the server detects that the current hydrogen content of any hydrogen storage device is below the hydrogen content threshold, it sends a hydrogen charging prompt signal to the server, indicating that the hydrogen storage device should be charged. The hydrogen charging prompt signal includes the digital identity of the hydrogen storage device to facilitate user identification.

[0099] like Figure 5 As shown, the present invention also discloses a hydrogen energy management system 1000, including a hydrogen storage device 1100, a hydrogen production / charging device 1200, a server 1300 and a user terminal 1400.

[0100] When the hydrogen production / charging device 1200 enters the hydrogen charging mode, the hydrogen production / charging device 1200 charges the hydrogen storage device 1100 with hydrogen;

[0101] The first read / write module in the hydrogen production / charging device 1200 reads the read / write memory of the hydrogen storage device 1100 to obtain the initial hydrogen content of the hydrogen storage device 1100, and the first display module of the hydrogen production / charging device 1200 displays the initial hydrogen content;

[0102] When the hydrogen charging increment of the hydrogen storage device 1100 exceeds the hydrogen charging increment threshold, the first read-write module writes the current hydrogen content of the hydrogen storage device 1100 into the read / write memory. When the hydrogen charging time of the hydrogen storage device 1100 exceeds the hydrogen charging time threshold, the first read-write module reads the read / write memory to obtain the current hydrogen content of the hydrogen storage device 1100, and the first display module of the hydrogen production / charging device 1200 displays the current hydrogen content.

[0103] When the hydrogen charging increment of the hydrogen storage device 1100 reaches the preset hydrogen charging threshold, the hydrogen production / charging device 1200 exits the hydrogen charging mode, the hydrogen production / charging device 1200 stops charging hydrogen into the hydrogen storage device 1100, the number of hydrogen charging times of the hydrogen storage device 1100 increases once, and the first read-write module writes the current hydrogen content and the number of hydrogen charging times of the hydrogen storage device 1100 into the read / write memory, and the hydrogen production / charging device 1200 feeds back the hydrogen charging increment, current hydrogen content, digital identity and number of hydrogen charging times of the hydrogen storage device 1100 to the server 1300.

[0104] Furthermore, the management system 1000 further includes a hydrogen-using device 1500 . When the hydrogen-using device 1500 enters a hydrogen-using mode, the hydrogen-using device 1500 consumes the hydrogen stored in the hydrogen storage device 1100 .

[0105] After adopting the above technical solution, compared with the existing technology, it has the following beneficial effects: the data of hydrogen energy equipment in various links such as hydrogen production, hydrogen filling, hydrogen storage and hydrogen use are connected, and visual management and calibration are carried out, which can accurately display the hydrogen content and overall improve the operating efficiency of hydrogen energy equipment and user experience.

[0106] It should be noted that the embodiments of the present invention have better practicability and do not impose any form of limitation on the present invention. Any technician familiar with the field may use the technical content disclosed above to change or modify it into an equivalent effective embodiment. However, any modification or equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
