The setting height of the second liquid level sensor is the height corresponding to the second protection liquid level (i.e., the highest liquid level corresponding to the preset minimum concentration of the electrolyte), that is, the second liquid level sensor can be used to detect whether the liquid level of the electrolyzed water in the electrolyzed water storage device is at or below the second protection liquid level.

[0039] A temperature sensor 215 is provided between the electrolyzed water storage device and the power device, and the temperature sensor is used to detect the temperature of the electrolyzed water.

[0040] In addition, the hydrogen production system also includes a computer device, which is respectively connected to each component in the hydrogen production system to receive the first transmission data transmitted by each component and send relevant control instructions to each component to realize automatic replenishment of electrolyzed water and water replenishment operations of the hydrogen production system.

[0041] The following is a detailed description of the embodiments in conjunction with the accompanying drawings. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments. Although the logical order is shown in the flow chart, in some cases, the steps shown or described may be performed in an order different from that shown in the accompanying drawings.

[0042] See also Figure 3 , provides a device control method, which can be applied to a terminal device or a server. The following takes the method applied to a computer device as an example for description, and the method includes steps 301 to 302:

[0043] 301. When it is detected that the current water level of the electrolyzed water in the electrolyzed water storage device reaches a preset protection liquid level, a water replenishment parameter required to replenish the electrolyzed water storage device is obtained, and a first water flow parameter of a first water outlet of the water replenishment device is obtained.

[0044] The duration of the hydrogen production process can be preset, and its duration can be determined according to the total amount of hydrogen to be produced, or can be preset. In the hydrogen production process, generally, it usually includes the following process: preparing electrolyzed water with a preset initial concentration, inputting the electrolyzed water into the electrolyzed water storage device, and electrolyzing the electrolyzed water in the electrolyzer. As the water in the electrolyzed water storage device is consumed, until the first liquid level sensor detects that the water in the electrolyzed water storage device is consumed to the protection liquid level, the computer device will receive the liquid level sensor signal of the first liquid level sensor and start the water replenishment operation. The electrolyzed water includes but is not limited to alkaline solution.

[0045] Among them, the initial concentration of electrolyzed water can be preset. Since the hydrogen production efficiency is related to the concentration of electrolyzed water, in order to ensure that the hydrogen production efficiency meets the preset requirements (ideal efficiency), the concentration of the electrolyzed water has a corresponding target concentration range, and the initial concentration of the electrolyzed water can select any concentration value in the target concentration range, for example, select the maximum value in the target concentration.

[0046] In some embodiments, the hydrogen production system includes a first liquid level sensor, which is arranged in the electrolyzed water storage device, and the first liquid level corresponding to the first liquid level sensor is the protective liquid level of the electrolyzed water in the electrolyzed water storage device; the method also includes: when a water-free signal transmitted by the first liquid level sensor is obtained, it is determined that the electrolyzed water in the electrolyzed water storage device has reached a preset protective liquid level.

[0047] In order to optimize the structure of the hydrogen production system, reduce the failure rate, and reduce the cost of the hydrogen production system, the first water flow parameter of the first water outlet can be collected by simply setting a simple target sensor, wherein the target sensor is a pressure sensor, which is set between the water replenishment equipment and the first solenoid valve. The first water flow parameter may include the first water pressure of the first water outlet of the water replenishment equipment.

[0048] In some embodiments, the hydrogen production system includes an electrolyzer, and obtaining water replenishment parameters that need to be replenished to the electrolytic water storage device may include: obtaining the first operating time, working current, and water consumption per unit current of the electrolyzer. The first operating time is characterized by the operating time of the electrolyzer from the last time the water replenishment started to the current moment, and the last time the water replenishment process started may include the process of replenishing electrolytic water and the process of replenishing water.

[0049] Optionally, obtaining the first operating time of the electrolytic cell may include: recording the time of preset nodes (the last time the electrolytic cell started to replenish water and the current moment) through a timing device, and obtaining the first operating time by calculating the time difference between corresponding nodes.

[0050] Optionally, the operating current and the water consumption per unit current of the electrolytic cell can be obtained by measuring or reading a work manual of the electrolytic cell.

[0051] In some embodiments, obtaining a first water flow parameter of a first water outlet of a water replenishment device may include: obtaining a first water pressure and a first cross-sectional area of ​​the first water outlet of the water replenishment device;

[0052] Optionally, the first water pressure may be collected by a preset pressure sensor (disposed in a pipeline between the water replenishment device and the first solenoid valve).

[0053] Optionally, the first cross-sectional area of ​​the first water outlet of the water replenishment device may be obtained by measuring.

[0054] 302. Determine a first water replenishment time required to replenish water to the electrolyzed water storage device according to the water replenishment parameter and the first water flow parameter, so as to control the opening time of the first solenoid valve of the water replenishment device according to the first water replenishment time.

[0055] In some embodiments, the hydrogen production system includes an electrolyzer, and the water replenishment parameters include a first operating time, an operating current, and a water consumption per unit current, and an operating current, and a water consumption per unit current of the electrolyzer; the first water flow parameter includes a first water pressure and a first cross-sectional area of ​​a first water outlet of the water replenishment device; determining a first water replenishment time required to replenish water to the electrolyzed water storage device based on the water replenishment parameters and the first water flow parameters includes: determining the first water replenishment time required to replenish water to the electrolyzed water storage device based on the first operating time, the operating current, the water consumption per unit current, the first water pressure and the first cross-sectional area.

[0056] In the embodiment of the present application, by selecting fewer categories and quantities of sensor data, the first water replenishment time required to replenish water to the electrolyzed water storage device can be determined, thereby reducing the structural requirements of the device used for water replenishment in the hydrogen production equipment, thereby reducing costs.

[0057] In some embodiments, a first water replenishment time required to replenish water to the electrolyzed water storage device is determined based on the first operating time, the operating current, the water consumption per unit current, the first water pressure and the first cross-sectional area, including: determining the target water consumption of the electrolytic cell based on the first operating time, the operating current and the first product of the water consumption per unit current; determining the water flow rate of the first water outlet based on the first water pressure and the first cross-sectional area; determining the first water replenishment time required to replenish water to the electrolyzed water storage device based on the target water consumption and the water flow rate.

[0058] In some embodiments, the target water consumption V3 of the electrolytic cell is determined according to the first operating time, the operating current and the first product of the water consumption per unit current, and the following formula (1) may be used:

[0059] V3= k * I * t (1)

[0060] Wherein, k is the water consumption per unit current, I is the working current, and t is the first operating time.

[0061] In some embodiments, the water flow rate Q of the first water outlet is determined according to the first water pressure and the first cross-sectional area, and specifically the following formula (2) may be used:

[0062] Q=(μ*A*(2P2 / ρ)^0.5)*60000 (2)

[0063] Among them, μ is the flow coefficient 0.6~0.65, A is the first cross-sectional area, P2 is the first water pressure, and ρ is the density of water.

[0064] Optionally, determining the first water replenishment time required to replenish the electrolyzed water storage device with water according to the target water consumption and the water flow rate may include: comparing the target water consumption with the water flow rate to obtain a first ratio, and using the first ratio as the first water replenishment time t1 required to replenish the electrolyzed water storage device with water. Specifically, as shown in the following formula (3):

[0065] t1=V3 / Q=(k * I * t) / [(μ*A*(2P2 / ρ)^0.5)*60000] (3)

[0066] Among them, t1 is the first water replenishment time.

[0067] In the embodiment of the present application, when it is detected that the electrolyzed water in the electrolyzed water storage device reaches a preset protection liquid level, the water replenishment parameter required to replenish the electrolyzed water storage device is obtained, and the first water flow parameter of the first water outlet of the water replenishment device is obtained. The time required for water replenishment can be quickly and accurately determined based on the water replenishment parameter and the first water flow parameter, so as to control the opening time of the first solenoid valve of the water replenishment device according to the water replenishment time, thereby improving the accuracy and convenience of automatic water replenishment in the hydrogen production process, and at the same time, the requirements for measuring instruments of the hydrogen production system are low, so that the cost is low.

[0068] Since there are still many unstable situations in the early operation of the hydrogen production system, as the hydrogen production system runs for a period of time, the hydrogen production system tends to be stable. In order to improve the energy consumption of the hydrogen production system, in some embodiments, the method also includes: obtaining a first water replenishment time set corresponding to a preset number of water replenishment processes; determining a second water replenishment time according to the first water replenishment time set, so as to control the opening time of the first solenoid valve of the water replenishment equipment according to the second water replenishment time.

[0069] The number of preset times is at least two times, for example, two times, three times, five times or more times.

[0070] In this way, the opening time of the first solenoid valve of each water replenishment device can be controlled by adopting the second water replenishment time, thereby reducing the continuous dependence on the sensor device and reducing energy consumption.

[0071] Optionally, determining a second water replenishment duration according to the first water replenishment duration set includes:

[0072] Determine an average value of a first water replenishment time set required to replenish water to the electrolyzed water storage device, and use the average water replenishment time as a second water replenishment time.

[0073] In some embodiments, the method further includes: obtaining the hydrogen production efficiency of the hydrogen production system within a preset time period; if the hydrogen production efficiency is lower than a preset efficiency threshold, generating a control instruction to update the second water replenishment duration according to the control instruction.

[0074] In some embodiments, the method further includes: obtaining a first water replenishment duration set corresponding to a preset number of water replenishment processes; determining a water replenishment duration correction parameter based on the first water replenishment duration set, so as to correct the first water replenishment duration based on the water replenishment duration correction parameter.

[0075] Optionally, determining the water replenishment duration correction parameter according to the first water replenishment duration set may include: extracting duration features in the first water replenishment duration set, and self-learning the duration features through a preset self-learning model to obtain the water replenishment duration correction parameter.

[0076] Among them, the self-learning model can include an autoregressive integrated moving average model, an autoregressive model, and a self-learning evaluator.

[0077] In the above embodiment, the first water replenishment time is corrected by the water replenishment time correction parameter to improve the accuracy of water replenishment, so that the concentration of electrolyzed water is maintained at an appropriate concentration, the electrolysis efficiency of the electrolyzer is improved, and the hydrogen production efficiency of the hydrogen production system is improved.

[0078] Since the temperature of the water in the water replenishment equipment is usually significantly different from the temperature of the electrolyzed water in the hydrogen production system (the water replenishment equipment has not been subjected to temperature control treatment, and its temperature is similar to the ambient temperature, while the electrolyzed water in the hydrogen production system generates heat due to the electrolysis process of the electrolyzer, so that the temperature of the electrolyzed water flowing back to the electrolyzed water storage equipment is higher), in some embodiments, the hydrogen production system also includes a temperature sensor, and the method also includes: during the water replenishment process, obtaining the real-time temperature of the electrolyzed water in the electrolyzed water storage equipment through the temperature sensor; generating an opening instruction and a closing instruction of the first solenoid valve of the water replenishment equipment according to the real-time temperature, so as to control the opening and closing of the first solenoid valve of the water replenishment equipment according to the opening instruction and the closing instruction, so that the real-time temperature is not lower than the preset temperature threshold, and the total opening time of the first solenoid valve is not less than the first water replenishment duration.

[0079] Optionally, the opening instruction and the closing instruction of the first solenoid valve of the water replenishment device are generated according to the real-time temperature, including: if the real-time temperature drops below a preset first temperature threshold, a closing instruction of the first solenoid valve of the water replenishment device is generated; if the real-time temperature rises back to above a preset second temperature threshold, an opening instruction of the first solenoid valve of the water replenishment device is generated.

[0080] In the above-mentioned embodiment, the real-time temperature of the electrolyzed water in the electrolyzed water storage device is monitored, and the water replenishment of the water replenishment device is controlled according to the real-time temperature, so as to prevent the temperature of the electrolyzed water from fluctuating greatly due to the water replenishment, thereby preventing the electrolysis efficiency of the electrolytic cell from being reduced. At the same time, by controlling the total opening time of the first solenoid valve to be not less than the first water replenishment time, it is ensured that each water replenishment process can meet the water replenishment amount requirement. Therefore, while ensuring that the concentration of the electrolyzed water is within a suitable concentration range, it is also ensured that the temperature of the electrolyzed water is within a suitable temperature fluctuation range.

[0081] In addition, the present application controls the water replenishment of the water replenishment equipment according to the real-time temperature, rather than using a heating device to heat the electrolyzed water. The high-temperature water of the electrolyzer is neutralized with the low-temperature water of the water replenishment equipment to make the temperature of the mixed electrolyzed water appropriate. This not only ensures the temperature requirement of the electrolyzer for the electrolyzed water, but also saves energy and reduces the cost of hydrogen production.

[0082] In some embodiments, the present application provides a device control method, which is applied to a hydrogen production system, wherein the hydrogen production system includes an electrolyzed water storage device and an electrolyzed water replenishing device, such as Figure 4 As shown, the method includes steps 401 to 402:

[0083] 401. In a process of adding electrolyzed water to an electrolyzed water storage device, a preset target liquid level of the electrolyzed water in the electrolyzed water storage device and a second water flow parameter of a second water outlet of an electrolyzed water replenishing device are obtained.

[0084] 402. If it is detected that the electrolyzed water in the electrolyzed water storage device reaches a preset protection liquid level, the third water replenishment time required to replenish the electrolyzed water to the electrolyzed water storage device is determined according to the target liquid level, the protection liquid level and the second water flow parameter, so as to control the opening time of the second solenoid valve of the electrolyzed water replenishment device according to the third water replenishment time.

[0085] Among them, the second water flow parameter includes the second water pressure and the second cross-sectional area of ​​the second water outlet of the electrolyzed water replenishing equipment.

[0086] Optionally, the third water replenishment time required to replenish the electrolyzed water to the electrolyzed water storage device can be calculated according to the following formula (4):

[0087] t2={[(V2-V1)*β+V1] / [(μ*A*(2P1 / ρ)^0.5)*60000]}-[(μ*A*(2P1 / ρ)^0.5)]*60000 (4)

[0088] Among them, μ is the flow coefficient 0.6~0.65, A is the second cross-sectional area, P1 is the second water pressure, ρ is the density of water, V2 is the liquid level volume corresponding to the second liquid level sensor, V1 is the liquid level volume corresponding to the first liquid level sensor; t2 is the third water replenishment time, and β is the percentage of the ratio of the target liquid level to V2.

[0089] In the embodiment of the present application, a third water replenishment time required to replenish electrolyzed water to the electrolyzed water storage device is determined based on the target liquid level, the protection liquid level and the second water flow parameter, so as to control the opening time of the second solenoid valve of the electrolyzed water replenishment device according to the third water replenishment time, thereby realizing automatic addition of electrolyzed water without the need for complex sensing equipment, optimizing the structure of the automatic hydrogen production system and reducing costs.

[0090] In some embodiments, the method further includes: monitoring the liquid filling process of the electrolytic water replenishing equipment according to the third water filling time, and generating an alarm message if the liquid filling time exceeds the third water filling time.

[0091] In the above-mentioned embodiment, the safety of the hydrogen production system is improved by monitoring the liquid filling process of the electrolytic water replenishing equipment.

[0092] It should be understood that, although the steps in the flowcharts involved in the above embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0093] Based on the same inventive concept, the embodiment of the present application also provides a device control device for implementing the device control method involved above. The implementation solution provided by the device to solve the problem is similar to the implementation solution recorded in the above method, so the specific limitations in one or more device control device embodiments provided below can refer to the limitations on the device control method above, and will not be repeated here.
