Abstract
Description
Technical Field
[0001] The present application relates to the field of control and regulation, and in particular, to a monitoring method, electronic equipment and a hydrogen production and refueling station for an integrated hydrogen production and refueling station. Background Art
[0002] An integrated hydrogen production and refueling station is a place where the hydrogen production system and the hydrogen refueling system are built together, which generally includes hydrogen production equipment, hydrogen storage tanks, hydrogen compressors, hydrogen refueling machines, hydrogen transmission pipelines and other equipment. At present, the hydrogen production system usually produces hydrogen and oxygen by water electrolysis. The produced hydrogen is stored, pressurized and other processes are carried out, and then the hydrogen is consumed by the hydrogen refueling machine. There are many purposes for consumption, such as providing hydrogen energy for automobiles, reacting hydrogen with organic compounds for hydrogenation dealkylation, hydrogenation desulfurization and other processes.
[0003] In the process of hydrogen production, conductivity is an important parameter in the electrolysis process, which affects the electrolysis efficiency and the operating stability of the hydrogen production system and even the entire integrated hydrogen production and refueling station. However, the current hydrogen production system fails to effectively control conductivity, which reduces the stability of hydrogen production. Summary of the invention
[0004] The embodiments of the present application provide a monitoring method of an integrated hydrogen production and refueling station, an electronic device, and a hydrogen production and refueling station, so as to at least solve the technical problem of decreased stability of hydrogen production.
[0005] According to a first aspect of an embodiment of the present application, a monitoring method for an integrated hydrogen production and refueling station is provided, wherein the integrated hydrogen production and refueling station comprises a plurality of electrolyzers for producing hydrogen, wherein the plurality of electrolyzers form at least one group, wherein each group comprises at least two electrolyzers, and the electrolyzers in the same group have the same usage conditions, and the method comprises:
[0006] Acquire water outlet parameters of the water outlet end of the first electrolytic cell in the target group, wherein the water outlet parameters include parameters capable of changing the conductivity of electrolyzed water;
[0007] Processing the outlet water parameter using a preset conductivity correction model to obtain a correction value of the inlet water parameter for the first electrolytic cell and each second electrolytic cell, wherein the second electrolytic cell includes at least one electrolytic cell in the target group except the first electrolytic cell;
[0008] The water inlet parameters of the water inlet ends of the first electrolyzer and the second electrolyzer are corrected according to the correction value control parameter correction component to adjust the hydrogen production value of the hydrogen production system in the hydrogen production and refueling station; wherein the water inlet end of the first electrolyzer and the water inlet end of the second electrolyzer are both provided with parameter correction components, wherein the parameter correction components can correct the parameters related to the conductivity of the electrolyzed water.
[0009] By adopting this embodiment, the outlet water parameters of the first electrolyzer in the target group are monitored and the correction value is outputted using the preset conductivity correction model, so that when the outlet water parameters of the first electrolyzer are abnormal, the inlet water parameters of the electrolyzers in the entire target group can be corrected. Since the outlet water parameters include parameters that can change the conductivity of the electrolyzed water, the conductivity of the corrected inlet water parameters is easy to control within the normal range, so that the conductivity can be controlled in time, thereby improving the stability of hydrogen production.
[0010] In combination with the first aspect, in an optional implementation manner of the embodiment of the present application, the method further includes:
[0011] Acquire historical effluent parameters of the first electrolytic cell, preset effluent parameter thresholds, historical conductivity abnormality results of the first electrolytic cell, and historical effluent parameters of each of the second electrolytic cells from the historical operation data of the target group;
[0012] Using the historical outlet water parameter of the first electrolytic cell, the outlet water parameter threshold value and the historical conductivity abnormal result of the first electrolytic cell as first training data to train the conductivity correction model, so that the conductivity correction model can output a correction value for the inlet water parameter of the first electrolytic cell according to the outlet water parameter of the first electrolytic cell;
[0013] The conductivity correction model is trained using the historical water outlet parameters of the first electrolytic cell and the historical water outlet parameters of each of the second electrolytic cells as second training data, so that the conductivity correction model can output correction values for the water inlet parameters of each of the second electrolytic cells according to the water outlet parameters of the first electrolytic cell.
[0014] In this implementation, when training the conductivity correction model, the historical water outlet parameters of the first electrolyzer, the preset water outlet parameter threshold, the historical conductivity abnormal results of the first electrolyzer, and the historical water outlet parameters of each of the second electrolyzers are used, so that the trained conductivity correction model can derive the correction values of the first electrolyzer and each of the second electrolyzers based only on the water outlet parameters of the first electrolyzer. By using the conductivity correction model, it is beneficial to improve the fit between the correction value and the actual situation, thereby improving the stability of hydrogen production.
[0015] In combination with the first aspect, in an optional implementation of the embodiment of the present application,
[0016] The step of correcting the water inlet parameters of the water inlet ends of the first electrolytic cell and the second electrolytic cell according to the correction value comprises:
[0017] The corresponding parameter correction components are controlled to operate according to the correction values corresponding to the first electrolytic cell and the correction values corresponding to each of the second electrolytic cells, so as to change the water inlet parameters of the water inlet end of the first electrolytic cell and the corresponding water inlet parameters of the water inlet end of the second electrolytic cell.
[0018] By adopting this implementation method, the water inlet parameters of each electrolyzer in the target group are changed by setting the parameter corrector. Since the parameter corrector is hardware, the efficiency and accuracy of changing the water inlet parameters are high, which is beneficial to improving the stability of hydrogen production.
[0019] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the parameter correction member includes a first electrode plate and a second electrode plate, a coil for circulating a heat-conducting medium is provided on a side of the first electrode plate away from the second electrode plate, and the first electrode plate and the second electrode plate are respectively connected to the positive and negative electrodes of a power supply to adsorb metal ions in the electrolyzed water;
[0020] The step of controlling the corresponding parameter correction components to operate according to the correction value corresponding to the first electrolytic cell and the correction values corresponding to each of the second electrolytic cells comprises:
[0021] The power-on time of the corresponding parameter correction component and the temperature of the heat transfer medium in the coil are controlled according to the correction value.
[0022] With this implementation, after the first electrode plate and the second electrode plate are respectively connected to the positive and negative electrodes of the power supply and powered on, they are equivalent to a capacitor, which can adsorb metal ions in the electrolyzed water, reduce the concentration of metal ions in the electrolyzed water, and help change the conductivity of the electrolyzed water. In addition, a heat-conducting medium can flow through the coil, and after the heat-conducting medium exchanges heat with the electrolyzed water, it is beneficial to quickly change the temperature of the electrolyzed water, thereby changing the conductivity of the electrolyzed water. The parameter correction part can improve the conductivity of the electrolyzed water from two aspects at the same time, which is beneficial to improve the control efficiency and reliability of the conductivity, so that the conductivity of the electrolyzed water in the hydrogen production process is used to produce hydrogen, thereby improving the efficiency and stability of hydrogen production.
[0023] In combination with the first aspect, in an optional implementation of the embodiment of the present application, before the outlet water parameter is processed by using a preset conductivity correction model to obtain correction values for the first electrolytic cell and each second electrolytic cell, the method further includes:
[0024] Acquire water inlet parameters of the water inlet end of the first electrolytic cell, wherein the parameter type of the water inlet parameters is the same as the parameter type of the water outlet parameters;
[0025] Determining whether the water inlet parameter matches a preset water inlet parameter threshold;
[0026] If they match, the process of processing the outlet water parameters using the preset conductivity correction model is executed to obtain correction values for the first electrolytic cell and each second electrolytic cell;
[0027] If there is no match, the electrolyzed water at the water inlet end of the first electrolytic cell is adjusted so that the adjusted water inlet parameters of the electrolyzed water match the water inlet parameter threshold, the water outlet parameters at the water outlet end of the first electrolytic cell are re-obtained and the re-obtained water outlet parameters are processed using the conductivity correction model to obtain correction values for the first electrolytic cell and each second electrolytic cell.
[0028] By adopting this implementation, by judging the matching of the inlet parameters and the inlet parameter threshold, it is advantageous to adjust the inlet parameters of the electrolyzed water of the first electrolytic cell to within the normal range, and then re-acquire the outlet parameters to obtain the correction value. It is avoided that the outlet parameters are abnormal due to the abnormal inlet parameters. If the inlet parameters are corrected in this case, it is easy to increase the abnormal amplitude of the conductivity, which is conducive to the probability of adjusting the conductivity to within the normal range through the correction value.
[0029] In combination with the first aspect, in an optional implementation manner of the embodiment of the present application, the method further includes:
[0030] If the water inlet parameter matches the water inlet parameter threshold, an alarm is issued.
[0031] With this implementation, because what is obtained is the outlet water parameter, and the outlet water parameter is not conductivity, but a parameter that can change conductivity, when the inlet water parameter matches the inlet water parameter threshold, it proves that there is no problem with the conductivity of the electrolyzed water entering the electrolytic cell, but the outlet water parameter is abnormal, thereby realizing the monitoring of other abnormalities while monitoring conductivity.
[0032] In combination with the first aspect, in an optional implementation manner of the embodiment of the present application, the method further includes:
[0033] Obtaining the hydrogen production demand of the integrated hydrogen production and refueling station;
[0034] According to the hydrogen production of each group and the hydrogen production demand, the water inlet parameters of the first electrolyzer of at least one group are adjusted to increase or decrease the hydrogen production of the group so that the total hydrogen production of all groups reaches the hydrogen production demand.
[0035] With this implementation, as long as the situation of the first electrolyzer changes, the water inlet parameters of all the second electrolyzers in the target group will be synchronously corrected, so that the overall hydrogen production of this group changes. Using this feature, when controlling the hydrogen production of the entire hydrogen production and refueling station, it is only necessary to control the water inlet parameters of the first electrolyzer in one group, which improves the convenience of controlling the hydrogen production.
[0036] In combination with the first aspect, in an optional implementation of an embodiment of the present application, the outlet water parameters include the temperature and / or metal ion concentration of electrolyzed water at the outlet end, and the inlet water parameters include the temperature and / or metal ion concentration of electrolyzed water at the inlet end.
[0037] With this implementation, both temperature and metal ion concentration will affect the conductivity of electrolyzed water. Therefore, monitoring the outlet water temperature and outlet water metal ion concentration of electrolyzed water can help improve the monitoring accuracy of conductivity.
[0038] According to a second aspect of an embodiment of the present application, an electronic device is provided, the electronic device comprising a memory and a processor;
[0039] The memory is used to store computer programs;
[0040] The processor is used to execute the computer program to implement the steps of the method described above.
[0041] According to a third aspect of an embodiment of the present application, an integrated hydrogen production and refueling station is provided, comprising a plurality of electrolyzers for producing hydrogen, wherein the plurality of electrolyzers form at least one group, each of the group comprises at least two electrolyzers, and the electrolyzers in the same group are used in the same manner, and the water inlet end of the first electrolyzer and the water inlet end of the second electrolyzer are both provided with a parameter corrector, wherein the parameter corrector can correct parameters related to the conductivity of electrolyzed water;
[0042] The integrated hydrogen production and refueling station adopts the steps of the method described above during the hydrogen production process.
[0043] In combination with the third aspect, in an optional implementation of the embodiment of the present application, the parameter correction component includes a first electrode plate and a second electrode plate, and a coil for circulating a heat-conducting medium is provided on the side of the first electrode plate away from the second electrode plate, and the first electrode plate and the second electrode plate are respectively connected to the positive and negative poles of a power supply to adsorb the metal ions in the electrolyzed water.
[0044] The technical effects obtained by the above-mentioned second to third aspects are similar to the technical effects obtained by the corresponding technical means in the first aspect, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art can understand that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not limit them to be necessarily different.
[0050] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.
[0051] In the process of hydrogen production, conductivity is an important parameter in the electrolysis process, which affects the electrolysis efficiency and the operating stability of the hydrogen production system and even the entire integrated hydrogen production and refueling station. However, the current hydrogen production system fails to effectively control conductivity, which reduces the stability of hydrogen production.
[0052] Based on this, the embodiment of the present application provides a monitoring method for an integrated hydrogen production and refueling station, wherein the integrated hydrogen production and refueling station includes a plurality of electrolytic cells for hydrogen production, wherein the plurality of electrolytic cells form at least one group, each group includes at least two electrolytic cells, and the electrolytic cells in the same group are used in the same manner. Figure 1 The flowchart of the monitoring method of the integrated hydrogen production and refueling station shown is a schematic diagram, and the method includes the following processing procedures.
[0053] S100, obtaining water outlet parameters of the water outlet end of the first electrolytic cell in the target group.
[0054] According to the type of the water output parameter, a corresponding sensor is selected for collection, and the current execution subject obtains the parameters collected by the sensor to obtain the water output parameter.
[0055] The water output parameters include parameters that can change the conductivity of the electrolyzed water. Specifically, the water output parameters include, for example, the temperature of the electrolyzed water, the metal ion concentration of the electrolyzed water, etc. This embodiment does not specifically limit this.
[0056] S102: Process the outflow water parameters using a preset conductivity correction model to obtain correction values of the inflow water parameters for the first electrolytic cell and each of the second electrolytic cells.
[0057] A conductivity correction model is pre-trained. After the outlet water parameters are obtained, the outlet water parameters are input into the conductivity correction model. After calculation by the conductivity correction model, a plurality of correction values are output respectively, including a correction value for the first electrolytic cell and a correction value for each second electrolytic cell.
[0058] The conductivity correction model may be a neural network model or a large model composed of multiple types of models. This embodiment does not specifically limit this. It is sufficient as long as the conductivity correction model can be used to obtain the correction value of the inlet water parameter according to the outlet water parameter.
[0059] For ease of understanding, in the present embodiment, since the usage conditions of the electrolytic cells in the same group are the same, for the first electrolytic cell and the second electrolytic cell in the target group, the water inlet and working conditions of each electrolytic cell are the same, specifically including that the electrolyzed water entering the first electrolytic cell and the second electrolytic cell is electrolyzed water that has undergone the same treatment and enters the electrolyzer at the same time, and then circulates to the water inlet end through the same path and treatment, and the working conditions of the first electrolytic cell and the second electrolytic cell are the same electrolytic cell structure, the same electrolytic cell area, the same electrolysis power, and the same working environment, etc.
[0060] Based on this, the first electrolytic cell is representative in the target group, that is, the effluent parameters of the first electrolytic cell and the effluent parameters of the second electrolytic cell will not deviate too much. Therefore, when the conductivity correction model processes the effluent parameters, it can first calculate the correction value of the first electrolytic cell, and then directly use the correction value as the correction value of each second electrolytic cell or use it as the correction value of the corresponding second electrolytic cell after correcting the correction value.
[0061] Preferably, even if the first electrolytic cell is exactly the same as the second electrolytic cell, there will be some deviations due to the position, raw material quality and control accuracy of the electrolytic current, and these deviations will not change much. For example, the water outlet parameter of the first electrolytic cell is 10, and the water outlet parameter of the second electrolytic cell is 9 due to certain factors. Then the difference between the water outlet parameters of the first electrolytic cell and the second electrolytic cell will fluctuate around 1. Therefore, according to this feature, correction can be performed on the basis of the correction value of the first electrolytic cell to obtain the correction value of each second electrolytic cell.
[0062] The second electrolytic cell includes at least one electrolytic cell in the target group except the first electrolytic cell.
[0063] S104, controlling the parameter correction component according to the correction value to correct the water inlet parameters of the first electrolyzer and the second electrolyzer to adjust the hydrogen production value of the hydrogen production system in the hydrogen production and refueling station.
[0064] Wherein, the water inlet end of the first electrolytic cell and the water inlet end of the second electrolytic cell are both provided with parameter correction components, wherein the parameter correction components can correct the parameters related to the conductivity of the electrolyzed water.
[0065] Since the first electrolytic cell has a corresponding correction value and the second electrolytic cell has a corresponding correction value, the corresponding water inlet parameters can be corrected according to the correction values corresponding to the respective electrolytic cells.
[0066] Among them, when correcting the water inlet parameters, the relevant parameters of the electrolyzed water at the water inlet end can be directly corrected according to the corresponding correction values. For example, if the water outlet parameter is the temperature of the electrolyzed water, the correction value also represents the temperature value, and when making the correction, the temperature of the electrolyzed water at the water inlet end can be directly corrected. As for the specific way of changing the parameters such as the electrolyzed water temperature and the metal ion concentration, this embodiment does not specifically limit this.
[0067] By adopting this embodiment, the outlet water parameters of the first electrolyzer in the target group are monitored and the correction value is outputted using the preset conductivity correction model, so that when the outlet water parameters of the first electrolyzer are abnormal, the inlet water parameters of the electrolyzers in the entire target group can be corrected. Since the outlet water parameters include parameters that can change the conductivity of the electrolyzed water, the conductivity of the corrected inlet water parameters is easy to control within the normal range, so that the conductivity can be controlled in time, thereby improving the stability of hydrogen production.
[0068] In a possible embodiment of the present application, Figure 2 As shown, the method also includes:
[0069] S200, obtaining historical water outlet parameters of the first electrolytic cell, preset water outlet parameter thresholds, historical conductivity abnormality results of the first electrolytic cell, and historical water outlet parameters of each second electrolytic cell from historical operation data of the target group.
[0070] During the operation of the target group, the operation data of the target group is continuously collected and stored to form historical operation data. The historical operation data includes the historical water outlet parameters, water outlet parameter thresholds, historical conductivity abnormal results of the first electrolyzer and the historical water outlet parameters of the second electrolyzer in the target group. Among them, the water outlet parameter threshold usually does not change, unless the first electrolyzer itself undergoes a major change, the water outlet parameter threshold will be adaptively modified. For example, the water outlet parameter is the temperature of the electrolyzed water at the water outlet of the first electrolyzer. When the parameters such as the volume and hydrogen production of the first electrolyzer do not change, the water outlet parameter threshold can be 22 degrees Celsius. If the volume and hydrogen production of the first electrolyzer change, the various parameters of the electrolysis process will also change accordingly. At this time, the water outlet parameter threshold can be re-determined.
[0071] S202, using the historical outlet water parameters of the first electrolytic cell, the outlet water parameter threshold value and the historical conductivity anomaly results of the first electrolytic cell as the first training data to train the conductivity correction model, so that the conductivity correction model can output a correction value for the inlet water parameter of the first electrolytic cell according to the outlet water parameters of the first electrolytic cell.
[0072] S204, using the historical water outlet parameters of the first electrolytic cell and the historical water outlet parameters of each second electrolytic cell as second training data to train the conductivity correction model, so that the conductivity correction model can output a correction value for the water inlet parameter of each second electrolytic cell according to the water outlet parameter of the first electrolytic cell.
[0073] It has been explained in the previous article that the water outlet parameters of the first electrolytic cell and the water outlet parameters of the second electrolytic cell have a linear relationship or a fixed ratio relationship. Therefore, this linear relationship or fixed ratio relationship can be determined based on the historical water outlet parameters of the first electrolytic cell and the historical water outlet parameters of each second electrolytic cell. Then, the conductivity correction model can convert the corrected value of each second electrolytic cell based on the corrected value of the first electrolytic cell according to this linear relationship or fixed ratio relationship.
[0074] In one embodiment, the training data may also include relevant parameters of the conductivity detector, such as usage time (how long has it been since the last conductivity cell constant calibration), electrode-related parameters, and other parameters, so that during use, the conductivity correction model can also obtain the operating parameters of the conductivity detector and input them into the conductivity correction model together with the outlet water parameters, so that the calculation process of the correction value will also take into account the defects of the conductivity detector, thereby improving the accuracy of the correction value.
[0075] In this embodiment, when training the conductivity correction model, the historical water outlet parameters of the first electrolyzer, the preset water outlet parameter threshold, the historical conductivity abnormality results of the first electrolyzer, and the historical water outlet parameters of each second electrolyzer are used, so that the trained conductivity correction model can derive the correction values of the first electrolyzer and each second electrolyzer based only on the water outlet parameters of the first electrolyzer. By using the conductivity correction model, it is beneficial to improve the fit between the correction value and the actual situation, thereby improving the stability of hydrogen production.
[0076] Optionally, in an implementation of this embodiment, the water inlet parameters of the water inlet ends of the first electrolytic cell and the second electrolytic cell are corrected according to the correction value, including:
[0077] The corresponding parameter correction components are controlled to operate according to the correction value corresponding to the first electrolytic cell and the correction value corresponding to each second electrolytic cell, so as to change the water inlet parameters of the water inlet end of the first electrolytic cell and the water inlet parameters of the corresponding second electrolytic cell.
[0078] The structure or capability of the parameter corrector is related to the type of water inlet parameter. For example, if the water inlet parameter is the temperature of the electrolyzed water, then the parameter corrector is a device that can change the temperature of the electrolyzed water. If the water inlet parameter is the metal ion concentration of the electrolyzed water, then the parameter corrector is a device that can change the metal ion concentration of the electrolyzed water.
[0079] After obtaining the correction value of the first electrolytic cell or the correction value of the second electrolytic cell, the parameter correction component at the water inlet end of the corresponding electrolytic cell is controlled to operate, so that the water inlet parameters of the electrolyzed water can be changed. It should be noted that the water inlet parameters of the electrolyzed water at the water inlet end of the electrolytic cell itself have a certain value. When changing the water inlet parameters according to the correction value, it is not necessary to know the original water inlet parameters of the electrolyzed water. For example, if the correction value is 3 degrees Celsius, it is proved that the temperature of the electrolyzed water needs to be increased by 3 degrees Celsius. At this time, according to the pre-set temperature change relationship, the temperature of the control parameter correction component is 5 degrees Celsius or 4 degrees Celsius, as long as the temperature of the electrolyzed water can be increased by 3 degrees Celsius.
[0080] With this embodiment, the water inlet parameters of each electrolyzer in the target group are changed by setting a parameter corrector. Since the parameter corrector is hardware, the efficiency and accuracy of changing the water inlet parameters are high, which is beneficial to improving the stability of hydrogen production.
[0081] Optionally, in an implementation of this embodiment, the parameter correction member includes a first electrode plate and a second electrode plate, a coil for circulating a heat-conducting medium is provided on a side of the first electrode plate away from the second electrode plate, and the first electrode plate and the second electrode plate are respectively connected to the positive and negative electrodes of a power source to adsorb metal ions in electrolyzed water;
[0082] According to the correction value corresponding to the first electrolytic cell and the correction values corresponding to each second electrolytic cell, the corresponding parameter correction components are controlled to operate respectively, including:
[0083] The power-on time of the corresponding parameter correction component and the temperature of the heat transfer medium in the coil are controlled according to the correction value.
[0084] Wherein, the heat-conducting medium can be water or oil, and this embodiment does not specifically limit this. The temperature of the water can be lower than the original temperature of the electrolyzed water to reduce the temperature of the electrolyzed water, or it can be higher than the original temperature of the electrolyzed water to increase the temperature of the electrolyzed water. The power-on time of the first electrode plate and the second electrode plate and the connection method of the positive and negative electrodes can also be configured according to demand. For example, when it is necessary to reduce the metal ion concentration of the electrolyzed water, the first electrode plate can be connected to the positive electrode of the power supply, and the second electrode plate can be connected to the negative electrode of the power supply. The electrolyzed water passes between the first electrode plate and the second electrode plate, and the metal ions in the electrolyzed water are affected by the electric field and / or magnetic field and adsorbed on the second electrode plate, so that the metal ion concentration in the electrolyzed water decreases. When it is necessary to increase the metal ion concentration of the electrolyzed water, the first electrode plate and the second electrode plate can be reversed so that the metal ions on the second electrode plate flow to the first electrode plate, and are taken away by the electrolyzed water during the period, so that the metal ion concentration in the electrolyzed water increases.
[0085] With this embodiment, after the first electrode plate and the second electrode plate are respectively connected to the positive and negative electrodes of the power supply and powered on, they are equivalent to a capacitor, which can adsorb metal ions in the electrolyzed water, reduce the concentration of metal ions in the electrolyzed water, and help change the conductivity of the electrolyzed water. In addition, a heat-conducting medium can flow through the coil, and after the heat-conducting medium exchanges heat with the electrolyzed water, it is beneficial to quickly change the temperature of the electrolyzed water, thereby changing the conductivity of the electrolyzed water. The parameter correction part can improve the conductivity of the electrolyzed water from two aspects at the same time, which is beneficial to improve the control efficiency and reliability of the conductivity, so that the conductivity of the electrolyzed water in the hydrogen production process is used to produce hydrogen, thereby improving the efficiency and stability of hydrogen production.
[0086] In other embodiments, the parameter correction component includes a plurality of integrated first electrode plates and a plurality of integrated second electrode plates, a rubber layer is provided between the plurality of first electrode plates so that electricity cannot be transmitted between the first electrode plates, and a rubber layer is provided between the plurality of second electrode plates so that electricity cannot be transmitted between the second electrode plates.
[0087] According to the correction value corresponding to the first electrolytic cell and the correction values corresponding to each second electrolytic cell, the corresponding parameter correction components are controlled to operate respectively, including:
[0088] The number of the first electrode plates and the second electrode plates that are energized is controlled according to the correction value.
[0089] Among them, when the first electrode plate and the second electrode plate are energized, the temperature of the first electrode plate and the second electrode plate will rise. Therefore, the temperature of the parameter correction component is different due to the different amount of power supply, and the ability to adsorb metal ions is also different, so that the parameter correction component can simultaneously change the temperature and metal ion concentration of the electrolyzed water.
[0090] Optionally, in an implementation of this embodiment, before using a preset conductivity correction model to process the outlet water parameters to obtain correction values for the first electrolytic cell and each second electrolytic cell, the method further includes:
[0091] Acquire water inlet parameters of a water inlet end of the first electrolytic cell, wherein the parameter type of the water inlet parameters is the same as the parameter type of the water outlet parameters;
[0092] Determine whether the water inlet parameter matches the preset water inlet parameter threshold;
[0093] If they match, the water outlet parameters are processed using a preset conductivity correction model to obtain correction values for the first electrolytic cell and each of the second electrolytic cells;
[0094] If they do not match, the electrolyzed water at the water inlet end of the first electrolytic cell is adjusted so that the adjusted water inlet parameters of the electrolyzed water match the water inlet parameter threshold, the water outlet parameters at the water outlet end of the first electrolytic cell are re-obtained and the re-obtained water outlet parameters are processed using the conductivity correction model to obtain correction values for the first electrolytic cell and each second electrolytic cell.
[0095] By adopting this embodiment, by judging the matching of the inlet water parameter and the inlet water parameter threshold, it is advantageous to adjust the inlet water parameter of the electrolyzed water of the first electrolytic cell to within the normal range, and then re-acquire the outlet water parameter to obtain the correction value. It is avoided that the outlet water parameter is abnormal due to the abnormal inlet water parameter. If the inlet water parameter is corrected in this case, it is easy to increase the abnormal amplitude of the conductivity, which is conducive to the probability of adjusting the conductivity to within the normal range through the correction value.
[0096] Optionally, in an implementation of this embodiment, the method further includes:
[0097] If the water inlet parameter matches the water inlet parameter threshold, an alarm is issued.
[0098] In this embodiment, because what is obtained is the water outlet parameter, and the water outlet parameter is not conductivity, but a parameter that can change conductivity, when the water inlet parameter matches the water inlet parameter threshold, it is proved that there is no problem with the conductivity of the electrolyzed water entering the electrolytic cell, but the water outlet parameter is abnormal, thereby realizing the monitoring of other abnormalities while monitoring the conductivity.
[0099] Optionally, in an implementation of this embodiment, the method further includes:
[0100] Obtain the hydrogen production demand of the integrated hydrogen production and refueling station;
[0101] According to the hydrogen production and hydrogen production demand of each group, the water inlet parameters of the first electrolyzer of at least one group are adjusted to increase or decrease the hydrogen production of the group so that the total hydrogen production of all groups meets the hydrogen production demand.
[0102] That is to say, when the total amount of hydrogen produced by each group is less than the hydrogen production demand, the water inlet parameters of the first electrolyzer of at least one group are adjusted in the direction of increasing the hydrogen production, so that the total amount of hydrogen produced by each group reaches the hydrogen production demand. When adjusting the water inlet parameters, you can first determine the adjustment direction of the water inlet parameters that can increase the hydrogen production, and then make adjustments. As for the adjustment direction, it can be determined by means of a preset table. For example, the preset table has the optimal hydrogen production range of each type of water inlet parameters. If it is necessary to increase the hydrogen production, the water inlet parameters are adjusted in the direction close to the optimal hydrogen production range, otherwise the water inlet parameters are adjusted in the direction away from the optimal hydrogen production range.
[0103] With this embodiment, as long as the situation of the first electrolyzer changes, the water inlet parameters of all the second electrolyzers in the target group will be synchronously corrected, so that the overall hydrogen production of this group changes. With this feature, when controlling the hydrogen production of the entire hydrogen production and refueling station, it is only necessary to control the water inlet parameters of the first electrolyzer in one group, which improves the convenience of controlling the hydrogen production.
[0104] Optionally, in an implementation of this embodiment, the outlet water parameters include the temperature and / or metal ion concentration of electrolyzed water at the outlet end, and the inlet water parameters include the temperature and / or metal ion concentration of electrolyzed water at the inlet end.

[0106] In this embodiment, both temperature and metal ion concentration will affect the conductivity of electrolyzed water. Therefore, monitoring the outlet water temperature and the outlet water metal ion concentration of electrolyzed water can help improve the monitoring accuracy of the conductivity.
