Description

Technical Field

[0001] This invention relates to the field of electrolytic hydrogen production regulation technology, and more specifically, to a method for scheduling and managing electrolytic hydrogen production based on oxygen demand and by-product hydrogen consumption. Background Technology

[0002] In medical oxygen supply technology based on electrolysis to produce hydrogen and oxygen, the mainstream approach in the industry is to address how to continuously meet the oxygen demand of hospitals under conditions of renewable energy fluctuations. This usually involves using photovoltaic power generation as the power source for electrolysis, adjusting the operating power of the electrolysis device according to the current or predicted oxygen consumption of the hospital, and compensating for the oxygen supply gap by combining oxygen storage, hydrogen storage, or hydrogen fuel cell power regeneration. For example, in hospital settings equipped with photovoltaic power generation, electrolysis devices, hydrogen storage units and medical oxygen supply networks, there are rapid fluctuations in photovoltaic power due to cloud cover during the day, and there are short-term high-intensity oxygen demands such as the concentrated use of ventilators and increased oxygen consumption during surgery at night or during emergency rescue. At the same time, medical oxygen supply is also subject to hard constraints such as stable oxygen purity, continuous and uninterrupted oxygen supply, and the electrolysis device should not be frequently and significantly increased or decreased in load and started or stopped. Under this constraint, the mainstream approach will consistently reveal an observable and verifiable defect: although the system can continuously follow the fluctuations in hospital oxygen demand at the power regulation level, the electrolysis device will repeatedly enter the operating range that is not conducive to medical oxygen supply during frequent load tracking. This leads to increased fluctuations in oxygen purity, poor gas separation stability, unstable oxygen supply connection during switching phases, and accelerated decline in device lifespan. The root cause is that the existing technology treats the electrolysis device as an ordinary gas-producing device that can freely follow demand, adjusting the electrolysis load only based on the oxygen demand gap, without constraining the permissible operational migration mode of the electrolysis device under the condition of meeting medical oxygen supply requirements. The technical problem this application aims to solve is: how to prevent the electrolysis device from entering an operating range unfavorable to medical oxygen supply due to unconstrained load tracking under the condition of simultaneous fluctuations in hospital oxygen consumption and power supply, thereby achieving a stable and continuous output of medical oxygen. Summary of the Invention

[0003] To overcome the aforementioned deficiencies in the prior art, embodiments of the present invention provide an electrolytic hydrogen production scheduling and management method based on oxygen supply demand and by-product hydrogen consumption. This method first determines the continuous oxygen production permit range based on the oxygen supply demand during the target oxygen supply period, the current hydrogen storage status, and the hydrogen consumption capacity. Then, when the target oxygen supply demand exceeds the continuous oxygen production permit range, pre-consumption processing is performed. Finally, the updated continuous oxygen production permit range is used to determine the oxygen production unit combination, oxygen production execution plan, and rolling reconfiguration adjustment for the remaining time periods, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a method for scheduling and managing electrolytic hydrogen production based on oxygen supply demand and by-product hydrogen consumption, comprising: S1. Obtain the target oxygen supply amount, oxygen supply duration, current hydrogen storage amount, hydrogen consumption rate and by-product hydrogen generation per unit of oxygen production during the target oxygen supply period, solve the upper limit of the oxygen production range that the hydrogen storage unit can continuously accept new by-product hydrogen during the target oxygen supply period, and output the continuous oxygen production range. S2. Compare the target oxygen production demand with the continuous oxygen production permit range. When the target oxygen production demand exceeds the continuous oxygen production permit range, control the hydrogen consumption unit to perform pre-consumption processing on the stored hydrogen before the start of the target oxygen supply period and output the updated continuous oxygen production permit range. S3. Based on the target oxygen supply, oxygen supply duration and the updated continuous oxygen production permit range, determine the target oxygen production unit combination from multiple oxygen production units, and determine the start-up sequence, load sharing ratio and continuous operation duration of each target oxygen production unit, and output the target oxygen production execution plan. S4. Control each target oxygen production unit to perform electrolytic oxygen production according to the target oxygen production execution plan, and simultaneously control the hydrogen consumption unit to consume the corresponding by-product hydrogen, and output the process status of medical oxygen and by-product hydrogen. S5. Based on the status of medical oxygen and by-product hydrogen processes, recalculate the continuous oxygen production permit range corresponding to the remaining time period of the target oxygen supply period. If the recalculated continuous oxygen production permit range is less than the current remaining target oxygen production demand, re-execute the pre-consumption treatment and target oxygen production execution plan determination until the medical oxygen supply output is completed.

[0005] In a preferred embodiment, S1 includes: S1-1. Obtain the target oxygen supply amount and oxygen supply duration to determine the target oxygen production demand corresponding to the target oxygen supply period.

S1-3. Perform constraint matching between the target by-product hydrogen demand result and the continuous acceptance capacity result, and solve the upper limit of the oxygen production range that the hydrogen storage unit can continuously accept during the target oxygen supply period based on the constraint matching result, and output the continuous oxygen production permit range.

[0006] In a preferred embodiment, the process of outputting the continuous reception capacity result in S1-2 further includes: S1-21. Based on the current hydrogen storage capacity, the upper limit of the hydrogen storage unit capacity and the hydrogen storage safety boundary, determine the current acceptable margin of the hydrogen storage unit, and construct a time period acceptance constraint set with the cumulative occupied amount of by-product hydrogen during the target oxygen supply period, the violation amount of the hydrogen storage safety boundary and the coverage status of the oxygen supply duration. The time period acceptance constraint set includes hydrogen storage occupancy constraints, absorption continuity constraints and time period coverage constraints. Output the current acceptable margin result and the time period acceptance constraint set. S1-22. Construct segmented consumption trajectories within the target oxygen supply period based on the hydrogen consumption rate and oxygen supply duration. Perform continuity verification, fluctuation consistency verification, and boundary arrival verification on the consumption rate of each segment. When verification conflicts exist, perform segmented correction based on the hydrogen storage occupancy increment and time period coverage gap until the corrected segments of each time period meet the time period acceptance constraint set. Output the hydrogen consumption capacity and segmented consumption verification results.

[0007] In a preferred embodiment, the process of outputting the continuous reception capacity result in S1-2 further includes: S1-23. Perform a joint solution with the current acceptable margin and the hydrogen consumption capacity, and solve the continuous acceptance capacity of the by-product hydrogen corresponding to the target oxygen supply period based on the acceptance coverage status, acceptance interruption status and constraint violation of the newly added by-product hydrogen during the target oxygen supply period. If the acceptance coverage status does not cover the target oxygen supply period or there is an interruption section in the acceptance interruption status, call the segmented consumption trajectory to perform a re-correction until a continuous acceptance capacity result with no acceptance interruption section and zero constraint violation is obtained during the target oxygen supply period.

[0008] In a preferred embodiment, S2 includes: S2-1. Determine the correspondence between the target oxygen production demand and the continuous oxygen production permit range, determine the demand difference between the target oxygen production demand and the continuous oxygen production permit range, and calculate the target pre-consumption amount to be released before the start of the target oxygen supply period based on the demand difference and the amount of by-product hydrogen generated per unit of oxygen production. Output the demand difference result and the target pre-consumption amount result. S2-2. Based on the target pre-consumption amount, the start time of the target oxygen supply period, and the corresponding consumption execution capacity of the hydrogen consumption unit, construct the pre-consumption execution sequence before the start of the target oxygen supply period, and control the hydrogen consumption unit to perform segmented pre-consumption of the stored hydrogen according to the pre-consumption execution sequence, and output the pre-consumption completion result and the remaining hydrogen storage status result.

[0009] In a preferred embodiment, S2 further includes: S2-3. Based on the remaining hydrogen storage status, recalculate the continuous oxygen production permit range corresponding to the target oxygen supply period, and re-perform the correspondence determination between the recalculated continuous oxygen production permit range and the target oxygen production demand. When the recalculated continuous oxygen production permit range covers the target oxygen production demand, output the updated continuous oxygen production permit range.

[0010] In a preferred embodiment, S3 includes: S3-1. Determine the time period oxygen demand sequence corresponding to the target oxygen supply period based on the target oxygen supply volume and oxygen supply duration, and divide the time period oxygen demand sequence into the permitted coverage area and the permitted restricted area according to the updated continuous oxygen production permit range, and output the segment division results and the oxygen production demand results corresponding to each segment. S3-2. Based on the segment division results, the oxygen production capacity per unit time period of each oxygen production unit, the amount of hydrogen produced as a byproduct of oxygen production, and the continuous operation status, perform a combination solution on multiple oxygen production units to determine the target oxygen production unit combination that meets the oxygen production needs of each segment and whose byproduct hydrogen production does not exceed the updated continuous oxygen production permit range. Output the target oxygen production unit combination results and the segment undertaking results corresponding to each target oxygen production unit.

[0011] In a preferred embodiment, S3 further includes: S3-3. Based on the target oxygen production unit combination results and the section assignment results, the execution timing and load allocation of each target oxygen production unit are arranged according to the section connection relationship. The start-up time, load sharing ratio and continuous running time of each target oxygen production unit are determined. When adjacent sections are handed over, the section oxygen production output and the section by-product hydrogen generation are kept within the allowable range of the corresponding section. The target oxygen production execution plan is then output.

[0012] In a preferred embodiment, S4 includes: S4-1. Control each target oxygen production unit to perform electrolytic oxygen production according to the target oxygen production execution plan, based on the corresponding start time, load sharing ratio and continuous running time. Simultaneously read the real-time oxygen production, real-time by-product hydrogen production, and real-time hydrogen consumption of each target oxygen production unit. Based on the real-time by-product hydrogen production and real-time hydrogen consumption, perform corresponding verification and cumulative balance calculations for the execution period, and output the oxygen production execution status and by-product hydrogen balance status for the current period. S4-2. Determine the medical oxygen process status and by-product hydrogen process status corresponding to the current time period based on the oxygen production execution status and by-product hydrogen balance status. When there is an unconsumed occupancy increment between the cumulative generation and cumulative consumption of by-product hydrogen in the current time period, as indicated by the by-product hydrogen balance status, write the unconsumed occupancy increment into the hydrogen storage unit status update result and output the medical oxygen and by-product hydrogen process status corresponding to the target oxygen supply period.

[0013] In a preferred embodiment, S5 includes: S5-1. Based on the process status of medical oxygen and the process status of by-product hydrogen, determine the completed oxygen supply, executed oxygen production, current hydrogen storage status and executed hydrogen consumption corresponding to the target oxygen supply period. Based on the total oxygen supply demand and total duration of the target oxygen supply period, solve for the remaining target oxygen production demand and remaining by-product hydrogen acceptance capacity corresponding to the remaining period, and output the remaining demand result and the remaining continuous oxygen production permit range. S5-2. Determine the correspondence between the remaining target oxygen production demand and the remaining continuous oxygen production permit range. When the remaining target oxygen production demand exceeds the remaining continuous oxygen production permit range, redetermine the pre-consumption amount and oxygen production unit reorganization result for the remaining time period based on the corresponding difference result, and output the pre-consumption adjustment instruction and oxygen production execution adjustment instruction for the remaining time period. S5-3. Control the hydrogen consumption unit to perform the pre-consumption processing corresponding to the remaining time period according to the pre-consumption adjustment instruction, and redetermine the target oxygen production execution plan corresponding to the remaining time period according to the oxygen production execution adjustment instruction, until the remaining continuous oxygen production permit range covers the remaining target oxygen production demand, and output the iterative adjustment result corresponding to the completion of medical oxygen supply output.

[0014] The technical effects and advantages of this invention are as follows: 1. This solution first solves the continuous oxygen production allowable range corresponding to the target oxygen supply period, and then uses the continuous oxygen production allowable range to constrain the subsequent pre-consumption, unit combination and execution reconfiguration process. This makes the electrolytic oxygen production no longer follow the load change without constraint based on the oxygen demand gap, thereby relatively suppressing the electrolysis device from entering the operating range that is not conducive to medical oxygen supply, and helping to achieve stable and continuous output of medical oxygen. 2. Convert the target oxygen production demand into the new by-product hydrogen demand, and incorporate the current acceptable margin, hydrogen consumption capacity and continuous by-product hydrogen acceptance capacity into the permissible scope calculation process, so as to establish a correspondence between oxygen production side adjustment and by-product hydrogen acceptance conditions, thereby relatively improving the hydrogen storage side mismatch problem caused by adjusting only from the oxygen side. 3. Before the start of the target oxygen supply period, pre-consumption processing is carried out on the demand difference that exceeds the continuous oxygen production permit range, so that the stored hydrogen can be released to make room for acceptance before the start of oxygen supply, thereby helping to alleviate the limitation on continuous oxygen production caused by the inability to continuously accept newly generated by-product hydrogen during the target oxygen supply period. 4. Based on the updated continuous oxygen production permit scope, the time-period oxygen production demand sequence is divided into permit coverage areas and permit restricted areas. Furthermore, the target oxygen production unit combination, its start-up sequence, load sharing ratio, and continuous operation duration are determined. This ensures that the oxygen production execution and by-product hydrogen generation in different areas are subject to unified permit constraints, thereby relatively improving the problem of disordered switching in the multi-unit oxygen production process. 5. During execution, the real-time oxygen production, real-time by-product hydrogen generation, and real-time hydrogen consumption are read simultaneously, and corresponding time period verification and cumulative balance calculation are performed to form the process status of medical oxygen and the process status of by-product hydrogen. This allows subsequent judgments to be based on the actual execution results, thereby relatively improving the consistency between process status identification and subsequent adjustment basis.

[0015] Figure 1 This is a flowchart outlining the method steps of the present invention. Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Refer to the instruction manual appendix Figure 1 The present invention provides a method for scheduling and managing hydrogen production via electrolysis based on oxygen demand and by-product hydrogen consumption, comprising: S1. Obtain the target oxygen supply amount, oxygen supply duration, current hydrogen storage amount, hydrogen consumption rate and by-product hydrogen generation per unit of oxygen production during the target oxygen supply period, solve the upper limit of the oxygen production range that the hydrogen storage unit can continuously accept new by-product hydrogen during the target oxygen supply period, and output the continuous oxygen production range. This implementation method describes how, before the start of the target oxygen supply period, the oxygen supply side first generates a result of the additional by-product hydrogen demand, and then the hydrogen storage side and hydrogen consumption side generate a result of the continuous acceptance capacity. Finally, based on the constraint relationship between the two, the continuous oxygen production permit range is determined, thus allowing the determination of whether the subsequent oxygen production process meets the conditions for continuous operation to be completed before the start of oxygen supply. The basic idea is: first, convert the target oxygen supply amount into the target oxygen production demand, and then convert the target oxygen production demand into the additional by-product hydrogen demand; then, based on the current hydrogen storage amount, hydrogen storage safety boundary, hydrogen consumption rate, and oxygen supply duration, the continuous acceptance capacity of by-product hydrogen within the target oxygen supply period is formed; finally, the additional by-product hydrogen demand and the continuous acceptance capacity of by-product hydrogen are constrained and matched to determine the continuous oxygen production permit range corresponding to the target oxygen supply period. The upper limit of the permitted oxygen production range is used as the caliber of the solution for the continuous oxygen production permit range. This implementation process includes the following steps: First, to shift the focus of subsequent assessment from the medical oxygen supply side to the by-product hydrogen receiving side, demand conversion is performed on the target oxygen supply volume and oxygen supply duration. Inputs include the target oxygen supply volume, oxygen supply duration, and the by-product hydrogen generation per unit of oxygen production. The target oxygen supply volume is given by the oxygen supply command from the medical oxygen supply network during the target oxygen supply period. The oxygen supply duration is determined by the start and end times corresponding to this command. The by-product hydrogen generation per unit of oxygen production is read from the process parameter table of the electrolytic oxygen generator under current operating conditions. Processing actions include: determining the target oxygen production demand corresponding to the target oxygen supply period based on the target oxygen supply volume and oxygen supply duration; when the target oxygen supply volume is given as the cumulative oxygen supply volume during the target oxygen supply period, it is directly used as the target oxygen production demand; when the target oxygen supply volume is given as the time-sharing oxygen supply flow rate, the oxygen supply flow rate at each sampling time within the target oxygen supply period is integrated and accumulated to obtain the target oxygen production demand. Subsequently, based on the amount of by-product hydrogen generated per unit of oxygen production, the target oxygen production demand is converted into the additional by-product hydrogen demand corresponding to the target oxygen supply period; the output is the target by-product hydrogen demand result, and the target by-product hydrogen demand result is written into the demand result record for subsequent constraint matching; when the target oxygen supply is missing, the most recent effective oxygen supply record corresponding to the current oxygen supply status is read and combined with the oxygen supply duration to form a substitute target oxygen supply; when the amount of by-product hydrogen generated per unit of oxygen production is missing, the default value of the process parameter table corresponding to the current electrolysis condition is read as the conversion basis. Subsequently, in order to form the total continuous acceptance of newly generated by-product hydrogen on the hydrogen storage side, the acceptance capacity is calculated for the current hydrogen storage, hydrogen consumption rate, and oxygen supply duration. The inputs include the current hydrogen storage, hydrogen consumption rate, and oxygen supply duration. The current hydrogen storage is read from the hydrogen storage unit status record, the hydrogen consumption rate is determined by the rated consumption parameter corresponding to the currently connected hydrogen consumption path and the actual consumption record in the most recent stable sampling segment, and the oxygen supply duration is read from the target oxygen supply period. The processing steps include: first, determining the current acceptable margin of the hydrogen storage unit based on the current hydrogen storage capacity; then, determining the hydrogen absorbable amount during the target oxygen supply period based on the hydrogen consumption rate and oxygen supply duration; and finally, solving for the continuous acceptance capacity of by-product hydrogen during the target oxygen supply period based on the current acceptable margin and the hydrogen absorbable amount. Here, the current acceptable margin represents the amount of by-product hydrogen that the hydrogen storage unit can still accept at the start of the target oxygen supply period; the hydrogen absorbable amount represents the amount of by-product hydrogen that the hydrogen consumption path can release during the target oxygen supply period; and the continuous acceptance capacity of by-product hydrogen represents the total amount of newly added by-product hydrogen accepted by the hydrogen storage unit and the hydrogen consumption path during the target oxygen supply period. The output is the continuous acceptance capacity result, which is written into the acceptance capacity result record for subsequent constraint matching. When the hydrogen consumption rate is interrupted or jumps, the continuous acceptance capacity result is not directly output; instead, the subsequent processes of refining the current acceptable margin, correcting the segmented consumption trajectory, and joint solving continue. After obtaining the target by-product hydrogen demand and continuous acceptance capacity results, in order to form the oxygen production range that the subsequent oxygen production process can enter, a constraint matching under a unified time caliber is performed on the two; the input includes the target by-product hydrogen demand and continuous acceptance capacity results; the processing actions include: firstly, aligning the target by-product hydrogen demand and continuous acceptance capacity results with the unified start and end times of the target oxygen supply period, and then performing constraint matching between the newly added by-product hydrogen demand and the continuous acceptance capacity of by-product hydrogen; When the demand for new by-product hydrogen falls within the acceptance boundary corresponding to the continuous acceptance capacity of by-product hydrogen, the oxygen production range corresponding to the target oxygen production demand is determined as the continuous oxygen production permit range. When the demand for new by-product hydrogen exceeds the acceptance boundary corresponding to the continuous acceptance capacity of by-product hydrogen, the upper limit of the allowable oxygen production range that the hydrogen storage unit can continuously accept during the target oxygen supply period is calculated in reverse using the continuous acceptance capacity of by-product hydrogen, and this upper limit of the allowable oxygen production range is output as the continuous oxygen production permit range. The output quantity is the continuous oxygen production permit range, and the continuous oxygen production permit range is written into the subsequent pre-consumption judgment process. When the time scale corresponding to the target by-product hydrogen demand result and the continuous acceptance capacity result is inconsistent, time scale normalization is performed first, and then constraint matching is performed to avoid distortion of the continuous oxygen production permit range caused by direct comparison under different time scales. Furthermore, to ensure that the current acceptable margin not only reflects the remaining acceptance space at the current time but also serves as the initial acceptance baseline for calculating the continuous acceptance capacity during the target oxygen supply period, constraints are applied to the current hydrogen storage quantity, the upper limit of the hydrogen storage unit capacity, and the hydrogen storage safety boundary. The input quantities include the current hydrogen storage quantity, the upper limit of the hydrogen storage unit capacity, the hydrogen storage safety boundary, and the duration of oxygen supply. The upper limit of the hydrogen storage unit capacity is read from the nameplate parameters or the operation parameter table of the hydrogen storage unit. The hydrogen storage safety boundary is determined based on the current pressure, temperature, and operating rules of the hydrogen storage unit, and its scope is the termination boundary that allows the continued addition of by-product hydrogen under the current operating conditions. The processing steps include: first, determining the actual acceptable upper limit based on the upper limit of the hydrogen storage unit capacity and the hydrogen storage safety boundary; then, subtracting the current hydrogen storage quantity from the actual acceptable upper limit to obtain the current acceptable margin. Subsequently, a time-period acceptance constraint set is constructed based on the cumulative occupancy of by-product hydrogen, the violation of the hydrogen storage safety boundary, and the coverage status of the oxygen supply duration during the target oxygen supply period. Among them, the hydrogen storage occupancy constraint is used to limit the cumulative occupancy of by-product hydrogen at any time to not exceed the actual upper limit of acceptance; the absorption continuity constraint is used to limit the absorption continuity between adjacent time-period segments to not be interrupted; and the time-period coverage constraint is used to limit the effective segment corresponding to the acceptance capacity to cover the entire oxygen supply duration. The output is the current acceptable margin result and the time-period acceptance constraint set, which are written into the acceptance basic result record and constraint record respectively for subsequent segment absorption trajectory correction reading; when the current hydrogen storage amount has reached the hydrogen storage safety boundary, the current acceptable margin is recorded as zero, and the time-period acceptance constraint set is marked as restricted. After forming the time period acceptance constraint set, in order to solve for the actual amount of hydrogen that can be consumed to cover the target oxygen supply period from the hydrogen consumption rate, the segmented consumption trajectory of the target oxygen supply period is constructed, verified, and corrected. The input quantities include the hydrogen consumption rate, the oxygen supply duration, and the time period acceptance constraint set. The hydrogen consumption rate can be given by the rated rate of the fixed consumption channel or by the average execution value in the most recent stable sampling segment. The processing actions include: firstly, dividing the target oxygen supply period into multiple continuous time period segments according to the oxygen supply duration, and taking the control refresh cycle or metering sampling cycle of the hydrogen consumption unit as the granularity of the division, thereby constructing the segmented consumption trajectory within the target oxygen supply period. The segmented consumption trajectory includes at least the start time, end time, segmented consumption rate, and segmented consumption amount of each segment. Then, continuity verification, fluctuation consistency verification, and boundary arrival verification are performed on the absorption rate of each time segment. Continuity verification determines whether there is an interruption in absorption between consecutive segments; fluctuation consistency verification determines whether the change in absorption rate of adjacent segments is consistent with the adjustment response record of the hydrogen absorption unit; and boundary arrival verification determines whether the change in hydrogen storage occupancy corresponding to the cumulative absorption of each segment reaches the actual acceptable upper limit. When verification conflicts exist, segment correction is performed based on the increase in hydrogen storage occupancy and the time segment coverage gap. Specifically, the time of the segment with interruption is first reallocated, and then the segment with... For segments with abnormal fluctuations, the execution rate is reverted according to the execution record of the adjacent stable segments. Finally, for segments that touch the boundary, the execution termination time is moved forward or the segment absorption amount is reduced until the corrected segments of each time period meet the time period acceptance constraint set. The output is the hydrogen absorption amount and the segment absorption verification result. The hydrogen absorption amount is obtained by accumulating the absorption amount of each corrected segment, and the segment absorption verification result is written into the subsequent joint solution process. When a segment's absorption rate is zero due to the disconnection of the absorption channel, the segment is recorded as an interrupted segment and will be given priority for time redistribution or subsequent segment compensation during subsequent corrections. Finally, to obtain the continuous reception capacity of by-product hydrogen that covers the entire target oxygen supply period without any interruption in reception, a joint solution is performed on the current reception capacity and the hydrogen absorption capacity. The inputs include the current reception capacity, the hydrogen absorption capacity, and the segmented absorption verification results. The processing steps include: first, using the current reception capacity as the reception baseline value at the start of the target oxygen supply period; then, superimposing the hydrogen absorption capacity onto the reception baseline value segment by segment according to the segmented absorption trajectory to form the reception coverage state corresponding to each segment within the target oxygen supply period; subsequently, based on the reception coverage state, reception interruption state, and constraint violation of each segment, the continuous reception capacity of by-product hydrogen corresponding to the target oxygen supply period is solved. The reception coverage state is used to determine whether each segment has the conditions for receiving new by-product hydrogen; the reception interruption state is used to determine whether there is a reception break between adjacent segments; and the constraint violation is used to determine whether any segment has a violation of hydrogen storage occupancy constraints, continuous absorption constraints, or period coverage constraints. When the acceptance coverage status does not cover the target oxygen supply period or there are interrupted sections in the acceptance interruption status, the segmented elimination trajectory is called to perform re-correction, and the segment-by-segment superposition and status determination are repeated until a continuous acceptance capacity result with no interrupted sections in the target oxygen supply period and zero constraint violation is obtained; the output is the continuous acceptance capacity result, and the continuous acceptance capacity result is written into the subsequent continuous oxygen production permit range calculation process; when there are still interrupted sections that cannot be eliminated after repeated correction, the continuous acceptance capacity result is output according to the total acceptance corresponding to the covered sections, and a restricted flag is written synchronously so as to compress the continuous oxygen production permit range during subsequent constraint matching; Through the above processing, the target by-product hydrogen demand is first determined by the target oxygen supply amount and the duration of oxygen supply. Then, the continuous acceptance capacity is determined by the current hydrogen storage amount, hydrogen storage safety boundary, hydrogen consumption rate, and segmented consumption trajectory. Finally, the continuous oxygen production permissible range is solved by matching the constraints between the target by-product hydrogen demand and the continuous acceptance capacity. This allows the judgment on whether the subsequent oxygen production process can continue to be completed before the start of the target oxygen supply period. After this processing, the subsequent pre-consumption is no longer executed on the abstract hydrogen storage balance, but on whether the newly added by-product hydrogen during the target oxygen supply period can be fully accepted. The input, calculation, judgment, and write-back criteria of the preceding and following steps remain consistent. In practical applications: When the hospital's main oxygen supply system issues a two-hour oxygen supply increase command during a certain nighttime period, the target oxygen production demand and the additional by-product hydrogen demand are first calculated based on the target oxygen supply volume and duration of the command. Then, the current hydrogen storage volume, the upper limit of the hydrogen storage unit capacity, and the hydrogen storage safety boundary are read to form the current acceptable margin, and a set of time-period acceptance constraints is constructed. Subsequently, based on the established hydrogen consumption paths, a segmented consumption trajectory is formed within the two hours. Corrections are performed on any interrupted sections, abnormal fluctuation sections, and boundary-touching sections to solve for the continuous acceptance capacity result within the two hours. If the continuous acceptance capacity result covers the additional by-product hydrogen demand, the continuous oxygen production permit range covering the nighttime period is output for subsequent oxygen production. If the continuous acceptance capacity result does not cover the additional by-product hydrogen demand, the restricted continuous oxygen production permit range is output and pre-consumption is triggered in subsequent processing.

[0018] S2. Compare the target oxygen production demand with the continuous oxygen production permit range. When the target oxygen production demand exceeds the continuous oxygen production permit range, control the hydrogen consumption unit to perform pre-consumption processing on the stored hydrogen before the start of the target oxygen supply period and output the updated continuous oxygen production permit range. This implementation method illustrates how, before the start of the target oxygen supply period, it is determined whether the target oxygen demand exceeds the continuous oxygen production permit range. Based on this, the target pre-consumption amount that needs to be released in advance is calculated, and segmented pre-consumption processing is performed by the hydrogen consumption unit to reconstruct the hydrogen storage unit state and update the continuous oxygen production permit range before the start of the target oxygen supply period. The basic principle is as follows: First, the demand difference is determined based on the correspondence between the target oxygen demand and the continuous oxygen production permit range. Then, this demand difference is converted into the target pre-consumption amount according to the by-product hydrogen generation per unit of oxygen production. Subsequently, a pre-consumption execution sequence is constructed based on the start time of the target oxygen supply period and the consumption execution capacity of the hydrogen consumption unit. Finally, the continuous oxygen production permit range corresponding to the target oxygen supply period is recalculated based on the remaining hydrogen storage state after pre-consumption, thereby ensuring that the subsequent oxygen production process has the corresponding by-product hydrogen acceptance conditions at the start of the target oxygen supply period. This implementation process includes the following steps: First, in order to transform the problem of insufficient continuous oxygen production capacity into an executable pre-consumption capacity, the correspondence between the target oxygen production demand and the continuous oxygen production capacity is determined. The input quantities include the target oxygen production demand, the continuous oxygen production capacity, and the by-product hydrogen generation per unit of oxygen production. The target oxygen production demand is read from the previous target oxygen supply conversion result, the continuous oxygen production capacity is read from the previous continuous acceptance capacity calculation result, and the by-product hydrogen generation per unit of oxygen production is read from the process parameter table corresponding to the current electrolysis condition. The processing steps include: first, aligning the target oxygen demand with the continuous oxygen production permit range according to the unified time caliber of the target oxygen supply period; then determining whether the target oxygen demand falls within the continuous oxygen production permit range. If the target oxygen demand falls within the continuous oxygen production permit range, the demand difference is recorded as zero; if the target oxygen demand exceeds the continuous oxygen production permit range, the excess portion is determined as the demand difference, and the target pre-consumption amount to be released before the start of the target oxygen supply period is calculated based on this demand difference and the amount of by-product hydrogen generated per unit of oxygen production; the outputs are the demand difference result and the target pre-consumption amount result, and the demand difference result is written into the pre-consumption judgment record, and the target pre-consumption amount result is written into the pre-consumption scheduling record for subsequent pre-consumption execution sequence construction and reading; when the time scale corresponding to the target oxygen demand and the continuous oxygen production permit range is inconsistent, time scale normalization is first performed according to the start and end times of the target oxygen supply period, and then the correspondence is determined to avoid direct comparison leading to distortion of the target pre-consumption amount; Subsequently, to ensure that the target pre-consumption amount is released along an executable path before the start of the target oxygen supply period, a timing sequence is executed for the target pre-consumption amount, the start time of the target oxygen supply period, and the consumption execution capacity corresponding to the hydrogen consumption unit. The input quantities include the target pre-consumption amount, the start time of the target oxygen supply period, and the consumption execution capacity corresponding to the hydrogen consumption unit. The consumption execution capacity is determined by the number of currently connected hydrogen consumption channels, the consumption capacity per unit time of each channel, the start executable time of each channel, and continuous operation limits. The processing actions include: first, deducing the allowable time interval for pre-consumption processing based on the start time of the target oxygen supply period, and then allocating the target pre-consumption amount to multiple pre-consumption segments within the time interval to form a pre-consumption execution sequence before the start of the target oxygen supply period. The pre-consumption execution sequence includes at least the start time, end time, segment pre-consumption amount, and corresponding consumption channel for each pre-consumption segment. Subsequently, the hydrogen consumption unit is controlled to perform segmented pre-consumption of the stored hydrogen according to the pre-consumption execution sequence. At the end of each segment, the correspondence between the actual segment consumption and the planned segment pre-consumption is read. When the actual segment consumption is less than the planned segment pre-consumption, the difference is written into the subsequent segment compensation record and the segment pre-consumption of the subsequent pre-consumption segment is adjusted. The output is the pre-consumption completion result and the remaining hydrogen storage status result. The pre-consumption completion result is used to characterize whether the target pre-consumption is released before the start of the target oxygen supply period. The remaining hydrogen storage status result is used to characterize the status of the hydrogen storage unit at the end of the pre-consumption and is written into the subsequent continuous oxygen production permit range recalculation process. When a consumption channel is interrupted during the execution, the uncompleted pre-consumption corresponding to that channel is transferred to other consumption channels that are still in the connected state. If the transfer cannot be completed, the uncompleted pre-consumption is written into the restricted flag for the subsequent continuous oxygen production permit range recalculation to compress the permit range. After obtaining the remaining hydrogen storage status results, in order to confirm whether the pre-consumption treatment has freed up the corresponding by-product hydrogen acceptance space for the target oxygen supply period, the continuous oxygen production permit range corresponding to the target oxygen supply period is recalculated and verified. The input quantities include the remaining hydrogen storage status results, the oxygen supply duration corresponding to the target oxygen supply period, the hydrogen consumption rate, and the by-product hydrogen generation per unit of oxygen production. The remaining hydrogen storage status results are read from the status write record corresponding to the pre-consumption completion results. The processing steps include: first, replacing the current hydrogen storage capacity before pre-consumption processing with the remaining hydrogen storage status result, and re-determining the current acceptable capacity, hydrogen consumption capacity, and by-product hydrogen continuous acceptance capacity using the previous continuous acceptance capacity calculation rules; then, calculating the continuous oxygen production permit range corresponding to the target oxygen supply period based on the re-determined by-product hydrogen continuous acceptance capacity; subsequently, performing a correspondence determination between the recalculated continuous oxygen production permit range and the target oxygen production demand; when the recalculated continuous oxygen production permit range covers the target oxygen production demand, the result is determined as the updated continuous oxygen production permit range; when the recalculated continuous oxygen production permit range still does not cover the target oxygen production demand, the uncovered portion is written into the continued pre-consumption demand record and kept marked as restricted; the output is the updated continuous oxygen production permit range, which is then written into the subsequent target oxygen production unit combination determination process; when the remaining hydrogen storage status result is missing, the last valid status record corresponding to the pre-consumption execution sequence is read as a substitute status for recalculation. Through the above processing, the demand difference is first determined by the correspondence between the target oxygen production demand and the continuous oxygen production permit range. Then, the target pre-consumption volume is converted from the demand difference. Subsequently, a pre-consumption execution sequence is constructed and segmented pre-consumption is completed based on the start time of the target oxygen supply period and the consumption execution capacity corresponding to the hydrogen consumption unit. Finally, the continuous oxygen production permit range is recalculated based on the remaining hydrogen storage status. Thus, the pre-consumption processing no longer corresponds to the abstract hydrogen storage release action, but rather to the pre-processing that frees up acceptance space for the new by-product hydrogen acceptance conditions before the start of the target oxygen supply period. After this processing, a continuous process is formed between the target oxygen production demand, the target pre-consumption volume, the remaining hydrogen storage status, and the updated continuous oxygen production permit range. The subsequent determination of oxygen production unit combination and execution plan arrangement can directly read the permit range results with a unified caliber. In practical applications: When the hospital's main oxygen supply system issues an instruction to increase oxygen supply for a specific morning surgery preparation period, the system first determines the correspondence between the target oxygen demand for that period and the permitted continuous oxygen supply range. If there is an excess, the excess is converted into a target pre-consumption amount that needs to be released before the start of oxygen supply. Subsequently, based on the operable window before the start of oxygen supply and the capacity of the currently connected hydrogen consumption channels, the target pre-consumption amount is divided into multiple pre-consumption segments and executed sequentially. After the segmented pre-consumption is completed, the permitted continuous oxygen supply range for that morning period is recalculated based on the updated remaining hydrogen storage status. If the recalculation result covers the target oxygen demand, the permitted continuous oxygen supply range is written into the subsequent oxygen unit combination determination process. If it still does not cover the target oxygen demand, the restricted status is maintained, and pre-consumption compensation or compression of the subsequent oxygen supply execution range continues in subsequent processing.

[0019] S3. Based on the target oxygen supply, oxygen supply duration and the updated continuous oxygen production permit range, determine the target oxygen production unit combination from multiple oxygen production units, and determine the start-up sequence, load sharing ratio and continuous operation duration of each target oxygen production unit, and output the target oxygen production execution plan. This implementation describes how, after completing the pre-consumption process and obtaining the updated continuous oxygen production permit range, the overall oxygen supply task within the target oxygen supply period is transformed into an executable multi-oxygen production unit collaborative operation scheme. This ensures that the subsequent electrolytic oxygen production process not only meets the oxygen production demand corresponding to the target oxygen supply amount and duration, but also ensures that the by-product hydrogen generation in each period is always constrained by the updated continuous oxygen production permit range. The basic principle is: first, a time-period oxygen production demand sequence corresponding to the target oxygen supply period is formed based on the target oxygen supply amount and duration; then, the updated continuous oxygen production permit range is used to identify... Within each time period, the sections that allow direct oxygen production and those requiring restricted scheduling are identified. Then, by combining the oxygen production capacity per unit time period of multiple oxygen production units, the amount of hydrogen produced as a byproduct per unit of oxygen production, and the continuous operating status, a combined solution for the oxygen production units is obtained. Finally, based on the section assignment results, the execution timing and load allocation for each target oxygen production unit are performed to form a target oxygen production execution plan. Here, multiple oxygen production units refer to multiple independently operable groups of electrolytic oxygen production units within the electrolytic oxygen production unit. Each oxygen production unit has its own independent start / stop control interface, operating status record, and oxygen production metering record. This implementation process includes the following steps: First, in order to transform the overall oxygen supply task within the target oxygen supply period into a time-sharing demand object that can participate in the unit combination solution, time-sharing demand expansion and segmentation are performed on the target oxygen supply amount, oxygen supply duration, and updated continuous oxygen production permit range. The inputs include the target oxygen supply amount, oxygen supply duration, and updated continuous oxygen production permit range. The target oxygen supply amount is read from the oxygen supply adjustment command, the oxygen supply duration is determined by the start and end times of the target oxygen supply period, and the updated continuous oxygen production permit range is read from the permit range result after pre-consumption processing. The processing steps include: first, continuously segmenting the target oxygen supply period according to the oxygen supply adjustment cycle or oxygen generation control refresh cycle, with the segmentation granularity set to the fixed refresh cycle of the oxygen generation unit controller, forming multiple sequentially arranged time period segments; then, determining the time period oxygen generation demand sequence based on the target oxygen supply allocation results within each time period segment. When the target oxygen supply is given as a total amount, allocation is performed according to the time ratio corresponding to the oxygen supply adjustment cycle; when the target oxygen supply is given as a time-based flow rate, the flow rates of each time period are directly accumulated as the corresponding time period oxygen generation demand; finally, determining the correspondence between the time period oxygen generation demand and the updated continuous oxygen generation permit range according to the same time period caliber. When the oxygen demand for a certain period falls within the continuous oxygen production permit range, that period is marked as a permit coverage segment. When the oxygen demand for a certain period exceeds the continuous oxygen production permit range, that period is marked as a permit restricted segment. Adjacent periods with the same marking are merged to form the final segment division result. The output includes the segment division result and the oxygen demand result corresponding to each segment, which are written to the segment record and segment demand record respectively for subsequent combination solution reading. When the oxygen supply instruction for a certain period segment is missing, the oxygen supply record of the previous valid period segment is read and supplemented according to the time proportion within the oxygen supply duration to avoid segment division interruption. Subsequently, in order to select a unit call structure from multiple oxygen production units that can cover the oxygen production needs of each section and meet the by-product hydrogen production permit constraints, a combined solution was performed on the section division results, the operating capacity parameters of each oxygen production unit, and the continuous operating status. The inputs included the section division results, the oxygen production demand results corresponding to each section, the oxygen production capacity per unit time period corresponding to each oxygen production unit, the by-product hydrogen production per unit oxygen production, and the continuous operating status. The oxygen production capacity per unit time period was determined by the actual oxygen production record and rated capacity parameters of each oxygen production unit within the most recent stable operating window. The by-product hydrogen production per unit oxygen production was read from the process parameter table corresponding to the current operating condition of each oxygen production unit. The continued operation status includes whether each oxygen production unit is currently running, its current continuous operating time, and whether continued operation is permitted. The processing actions include: first, performing a pre-screening of multiple oxygen production units to remove those that are in a fault state, out of service, or whose continuous operation status does not meet the conditions for continued operation; then, based on the oxygen production demand results corresponding to each section, performing a combination solution on the remaining oxygen production units. The rule for the combination solution is: the total oxygen production generated by each candidate oxygen production unit combination in the corresponding section covers the oxygen production demand of that section, and the total amount of by-product hydrogen generated by the candidate oxygen production unit combination in that section does not exceed the updated continuous oxygen production permit range. When multiple candidate oxygen production unit combinations meet the conditions, the candidate oxygen production unit combinations with fewer oxygen production unit switching times between adjacent sections are prioritized. Then, the final target oxygen production unit combination is determined based on the succession relationship corresponding to the continuous operation status of each oxygen production unit. The output includes the target oxygen production unit combination result and the section undertaking result corresponding to each target oxygen production unit. The section undertaking result includes at least the section identifier undertaken by each target oxygen production unit, the oxygen production undertaken in the section, and the corresponding by-product hydrogen generation in the section. The results are written into the combination result record and the undertaking result record for subsequent timing arrangement reading. When there is no oxygen production unit in a certain section that can independently cover the oxygen production demand of the section, the parallel combination of multiple oxygen production units is called as a candidate combination to continue solving. When the parallel combination still cannot cover the oxygen production demand of the section, the section is reserved as a restricted section and a restricted identifier is written. After obtaining the target oxygen production unit combination results and the segment allocation results, in order to form a control result that can directly drive multiple oxygen production units to perform electrolytic oxygen production, the segment allocation relationship is time-sequentially arranged and load-allocated. The inputs include the target oxygen production unit combination results, the segment allocation results, and the segment succession relationship. The segment succession relationship is determined by the order and handover time of each segment in the segment division results. The processing actions include: first, determining the start time and stop time of each target oxygen production unit within the target oxygen supply period based on the segment range undertaken by each target oxygen production unit. The start time is taken as the start time of the corresponding segment undertaken, and the stop time is taken as the end time of the corresponding segment undertaken. Then, based on the correspondence between the oxygen production amount undertaken by each target oxygen production unit in the corresponding segment and the total oxygen production demand of the segment, determining the load sharing ratio of each target oxygen production unit in the segment, and determining the continuous operating time of each target oxygen production unit based on the duration of each segment and the continuous segment range undertaken by each target oxygen production unit. Subsequently, during the handover between adjacent sections, the oxygen production output and by-product hydrogen generation at the end of the previous section and the beginning of the next section are checked. If the oxygen production output or by-product hydrogen generation of the section after the handover exceeds the permissible range of the corresponding section, the load sharing ratio and start-up time in the handover section are corrected by callback until the oxygen production output and by-product hydrogen generation of the section after the handover both fall within the permissible range of the corresponding section. The output is the target oxygen production execution plan, which includes at least the start-up time, load sharing ratio, continuous running time, and corresponding section of each target oxygen production unit. This target oxygen production execution plan is written into the subsequent oxygen production execution process. When a target oxygen production unit experiences a state change during the scheduling process, causing the original continuous operation state to fail, the combination result record and the undertaking result record are re-called to perform a partial rescheduling of the section where the target oxygen production unit is located, so as to avoid recalculating the entire execution plan for the target oxygen supply period. Through the above processing, the oxygen demand sequence for each time period is first formed from the target oxygen supply and the duration of oxygen supply. Then, based on the updated continuous oxygen production permit range, permit coverage sections and permit restricted sections are formed. Subsequently, the target oxygen production unit combination and the section undertaking result corresponding to each target oxygen production unit are solved from the operating capacity parameters and continuous operating status of multiple oxygen production units. Finally, the target oxygen production execution plan is formed based on the section succession relationship, thereby specifically implementing the constraint result of the continuous oxygen production permit range into the calling method, load allocation method, and continuous operation mode of multiple oxygen production units. After this processing, the subsequent oxygen production execution no longer makes unified adjustments to the overall target oxygen production demand, but performs segmented, unit-based, and time-series control based on the oxygen production demand and by-product hydrogen permit conditions in different sections. The input, calculation, judgment, and writing calibers between the preceding and following steps remain consistent. In practical applications: When a hospital issues a three-hour oxygen supply increase order within a morning oxygen supply window, and the continuous oxygen production permit obtained after pre-consumption processing can fully cover the oxygen production demand in the first hour, is partially restricted in the middle hour, and recovers coverage in the last hour, the three hours are first expanded into a time-period oxygen production demand sequence according to the oxygen production control refresh cycle, and divided into permit coverage sections and permit restricted sections. Then, the unit time-period oxygen production capacity, unit oxygen production by-product hydrogen generation, and continuous operation status of each oxygen production unit are read, and a combined solution is performed on multiple oxygen production units to determine that the first hour is jointly undertaken by the first and second oxygen production units, the middle hour is undertaken by the first oxygen production unit operating at reduced load and the introduction of the third oxygen production unit to supplement the load, and the last hour is undertaken by the first and second oxygen production units to resume the load. Finally, based on the load-sharing results of each section, the start time, load sharing ratio, and continuous operation duration of each oxygen production unit are arranged to form a target oxygen production execution plan covering the three-hour oxygen supply window, which can be directly called upon by subsequent oxygen production execution and by-product hydrogen synchronous consumption process.

[0020] S4. Control each target oxygen production unit to perform electrolytic oxygen production according to the target oxygen production execution plan, and simultaneously control the hydrogen consumption unit to consume the corresponding by-product hydrogen, and output the process status of medical oxygen and by-product hydrogen. This implementation method illustrates how, after the target oxygen production execution plan has been determined, the plan is implemented in the real-time execution process of each target oxygen production unit, and the correspondence between by-product hydrogen generation and hydrogen consumption is tracked synchronously during the execution process to form the medical oxygen process status and by-product hydrogen process status that can be directly called upon for recalculation in the remaining time period. The basic principle is as follows: First, each target oxygen production unit is driven to start operation at the corresponding time according to the target oxygen production execution plan, and the real-time oxygen production, real-time by-product hydrogen generation, and real-time hydrogen consumption of each target oxygen production unit are collected simultaneously. Then, using the start time of the target oxygen supply period as the cumulative starting point, the corresponding verification and cumulative balance calculation of by-product hydrogen generation and consumption execution periods within the current period are performed to solve the oxygen production execution status and by-product hydrogen balance status corresponding to the current period. Subsequently, the medical oxygen process status and by-product hydrogen process status are formed based on the status results, and the hydrogen storage unit status is updated when there is an unconsumed incremental usage, so that the recalculation of the continuous oxygen production allowance range in the remaining time period continues to use a unified standard. This implementation process includes the following steps: First, in order to transform the target oxygen production execution plan into verifiable oxygen production execution results and by-product hydrogen balance results within the current time period, real-time control, time period corresponding verification, and cumulative balance calculation are performed on each target oxygen production unit. The input quantities include the target oxygen production execution plan, the operating status record of each target oxygen production unit, the real-time oxygen production amount corresponding to each target oxygen production unit, the real-time by-product hydrogen generation amount, and the real-time hydrogen consumption amount corresponding to the hydrogen consumption unit. Among them, the target oxygen production execution plan includes at least the start time, load sharing ratio, continuous running time, and the section undertaken by each target oxygen production unit. The real-time oxygen production amount is collected by the oxygen production metering module of each target oxygen production unit according to the control refresh cycle. The real-time by-product hydrogen generation amount is collected by the hydrogen production metering module corresponding to each target oxygen production unit according to the same refresh cycle. The real-time hydrogen consumption amount is collected by the flow meter or consumption record module corresponding to the hydrogen consumption unit according to the same refresh cycle. The processing steps include: controlling each target oxygen production unit to start operation at its corresponding start time according to the target oxygen production execution plan; adjusting the corresponding oxygen production load of the target oxygen production units already in operation according to the load sharing ratio and maintaining this until the end of the corresponding continuous operation period of the target oxygen production unit; then, using the target oxygen supply period segment to which the current period belongs as a unified time caliber, performing period-based verification of the real-time by-product hydrogen generation and real-time hydrogen consumption. The period-based verification includes two parts: one is time-based verification, which determines whether the real-time by-product hydrogen generation and real-time hydrogen consumption in the current sampling period come from the same control refresh cycle; the other is execution-based verification, which determines whether the actual oxygen production output in the current sampling period is consistent with the planned oxygen production output of the target oxygen production execution plan in that period; after completing the period-based verification, using the start time of the target oxygen supply period as the cumulative starting point, performing cumulative balance calculation on the real-time by-product hydrogen generation and real-time hydrogen consumption in each sampling period, solving for the cumulative by-product hydrogen generation, cumulative consumption, and the difference between the two in the current period, and using the difference as the basis for determining the unconsumed incremental occupancy. The output includes the oxygen production execution status and by-product hydrogen balance status corresponding to the current time period. The oxygen production execution status includes at least the planned oxygen production, actual oxygen production, execution deviation, and target oxygen production unit operation status for the current time period. The by-product hydrogen balance status includes at least the cumulative by-product hydrogen production, cumulative by-product hydrogen consumption, and unconsumed hydrogen occupancy increment for the current time period. These results are written into the oxygen production execution status record and the by-product hydrogen balance status record for subsequent process status generation and reading. When a target oxygen production unit fails to start operation at the start time in the current time period, the target oxygen production unit is marked as an execution deviation unit, and the corresponding planned oxygen production gap is written into the execution deviation record for the current time period. When the real-time by-product hydrogen production or real-time hydrogen consumption is missing in a certain sampling period, the stable sampling value corresponding to the previous valid sampling period is read as the replacement value for the current sampling period, and a data replacement identifier is written to avoid interruption of cumulative balance calculation. Subsequently, in order to form a unified state result that can be directly read by the reconstruction of the remaining time periods, the oxygen production execution state and by-product hydrogen balance state corresponding to the current time period are merged, the occupancy increment is written, and the process result is output. The input includes the oxygen production execution state, the by-product hydrogen balance state, and the hydrogen storage unit state update result of the previous time period. The hydrogen storage unit state update result of the previous time period is formed by the unconsumed occupancy increment write result of the previous time period. The processing actions include: determining the medical oxygen process status for the current time period based on the oxygen production execution status. The medical oxygen process status includes at least the completed oxygen supply amount for the current time period, the oxygen production execution deviation for the current time period, and the oxygen supply continuity status for the current time period. The completed oxygen supply amount for the current time period is determined jointly based on the actual oxygen production amount for the current time period and the oxygen output records of the corresponding oxygen supply network. The oxygen supply continuity status for the current time period is determined based on whether there were any interruptions in the oxygen supply during the current time period. Simultaneously, determining the by-product hydrogen process status for the current time period based on the by-product hydrogen balance status includes at least the cumulative by-product hydrogen generation amount for the current time period, the cumulative by-product hydrogen consumption amount for the current time period, and the current... The unused occupancy increment for each period: When the by-product hydrogen balance state indicates that there is an unused occupancy increment between the cumulative generation and cumulative consumption of by-product hydrogen in the current period, the unused occupancy increment is superimposed with the hydrogen storage unit status update result of the previous period to form the hydrogen storage unit status update result for the current period. This current period hydrogen storage unit status update result is then written into the hydrogen storage status record as the input for the current hydrogen storage status for the remaining periods. When the by-product hydrogen balance state indicates that there is no unused occupancy increment between the cumulative generation and cumulative consumption of by-product hydrogen in the current period, the hydrogen storage unit status update result of the previous period remains unchanged and is directly written into the hydrogen storage status record for the current period. The output includes the medical oxygen process status and by-product hydrogen process status corresponding to the target oxygen supply period. The results are written into the oxygen supply process record and the by-product hydrogen process record respectively for recalculation and reading within the continuous oxygen production permit range for the remaining periods. When the oxygen supply completed in the current period is inconsistent with the oxygen output record corresponding to the oxygen supply network, the oxygen supply completed in the current period is corrected with the actual oxygen output record of the oxygen supply network. When the state update result of the hydrogen storage unit in the previous period is missing, the hydrogen storage state record of the most recent valid period is read as the basis for the current superposition and writing to ensure the continuity of the subsequent state chain. Through the above processing, the target oxygen production execution plan first drives each target oxygen production unit to perform electrolytic oxygen production in the current time period. Then, the real-time oxygen production, real-time by-product hydrogen generation, and real-time hydrogen consumption form the corresponding verification and cumulative balance calculation results for the time period. Subsequently, the results are merged to form the medical oxygen process status and by-product hydrogen process status, and the hydrogen storage unit status is updated synchronously when there is an unconsumed incremental usage. After this processing, the oxygen production execution results, by-product hydrogen generation results, hydrogen consumption results, and hydrogen storage status change results in the current time period are uniformly written into the same state chain. The recalculation of the continuous oxygen production permission range for the remaining time period does not require retracing the original execution data. It is only necessary to directly read the medical oxygen process status, by-product hydrogen process status, and hydrogen storage unit status update results to complete the subsequent judgment. The input, calculation, judgment, and writing caliber between the preceding and following steps are consistent. In practical applications: When a hospital has generated a target oxygen production execution plan for a certain continuous oxygen supply period, and the plan requires the first oxygen production unit to maintain basic load operation for the first 40 minutes, the second oxygen production unit to be added in parallel for the middle 20 minutes, and the third oxygen production unit to be withdrawn at the end, the target oxygen production units are first controlled to perform electrolytic oxygen production according to the corresponding start time, load sharing ratio, and continuous running time. At the same time, the real-time oxygen production and real-time by-product hydrogen generation of each target oxygen production unit and the real-time hydrogen consumption of the hydrogen consumption unit are collected. Then, taking the start time of the target oxygen supply period as the cumulative starting point, the corresponding verification and cumulative balance calculation of the by-product hydrogen generation and consumption execution periods in each sampling period are performed to solve the current oxygen production execution status and by-product hydrogen balance status. If the cumulative by-product hydrogen generation in a certain sampling period is higher than the cumulative by-product hydrogen consumption, the resulting unconsumed occupancy increment is written into the current period's hydrogen storage unit status update result and output together with the current period's medical oxygen process status and by-product hydrogen process status for recalculation of the continuous oxygen production allowable range and direct call for pre-consumption compensation judgment in the subsequent remaining periods.

[0021] S5. Based on the status of medical oxygen and by-product hydrogen processes, recalculate the continuous oxygen production permit range corresponding to the remaining period of the target oxygen supply period. If the recalculated continuous oxygen production permit range is less than the current remaining target oxygen production demand, re-execute the pre-consumption treatment and target oxygen production execution plan determination until the medical oxygen supply output is completed. This implementation method is used to illustrate how, after the target oxygen supply period has entered the execution process, the oxygen supply demand, oxygen production capacity and by-product hydrogen acceptance conditions for the remaining period are reconstructed in a rolling manner based on the current medical oxygen process status and by-product hydrogen process status, and when the continuous oxygen production allowance is insufficient, the pre-consumption adjustment and oxygen production execution reconstruction are triggered simultaneously to ensure that the subsequent part of the target oxygen supply period continues to complete the medical oxygen supply output along the unified constraint caliber. The basic principle is as follows: First, the completed oxygen supply, executed oxygen production, current hydrogen storage status, and executed hydrogen consumption are calculated from the current process status. Then, combined with the total oxygen supply demand and total duration of the target oxygen supply period, the remaining target oxygen production demand and remaining by-product hydrogen acceptance capacity for the remaining period are calculated, and the remaining continuous oxygen production permit range is formed in reverse. Subsequently, the correspondence between the remaining target oxygen production demand and the remaining continuous oxygen production permit range is determined. If there is an excess, the pre-consumption amount and oxygen production unit reorganization result for the remaining period are redefined. Finally, the remaining period is rearranged according to the pre-consumption adjustment instruction and the oxygen production execution adjustment instruction until the remaining continuous oxygen production permit range covers the remaining target oxygen production demand and completes the medical oxygen supply output corresponding to the target oxygen supply period. This implementation process includes the following steps: First, in order to transform the currently executed process into a refactoring input that can be directly invoked in the remaining time periods, the status of the medical oxygen process and the by-product hydrogen process are read, the remaining demand is calculated, and the permitted range is converted. The input quantities include the medical oxygen process status, the by-product hydrogen process status, the total oxygen supply demand and the total duration of the target oxygen supply period. Among them, the medical oxygen process status includes at least the amount of oxygen supplied in the current period, the oxygen production execution deviation in the current period, and the oxygen supply continuity status in the current period. The by-product hydrogen process status includes at least the cumulative amount of by-product hydrogen generated in the current period, the cumulative amount of by-product hydrogen consumed in the current period, and the incremental amount of unconsumed hydrogen occupied in the current period. The total oxygen supply demand and the total duration of the target oxygen supply period are read from the target oxygen supply instruction. The processing steps include: first, determining the completed oxygen supply amount corresponding to the target oxygen supply period based on the medical oxygen process status, and determining the executed oxygen production amount based on the oxygen production execution record; then, determining the current hydrogen storage status and executed hydrogen consumption amount based on the by-product hydrogen process status and the most recently written hydrogen storage unit status update result. The current hydrogen storage status is formed by adding the hydrogen storage status update result of the previous period to the unconsumed occupancy increment of the current period, and the executed hydrogen consumption amount is directly read from the cumulative by-product hydrogen consumption amount of the current period; then, subtracting the completed oxygen supply amount from the total oxygen supply demand of the target oxygen supply period to obtain the remaining target oxygen supply demand, and converting it with the by-product hydrogen generation amount corresponding to the unit oxygen production to form the remaining target oxygen production demand; then, resolving the remaining by-product hydrogen acceptance capacity based on the current hydrogen storage status, the remaining period duration, and the consumption capacity corresponding to the current hydrogen consumption path, and then calculating the remaining continuous oxygen production permit range based on the remaining by-product hydrogen acceptance capacity. The output includes the remaining demand result and the remaining continuous oxygen production permit range, and is written to the remaining demand record and the remaining permit record respectively for subsequent correspondence determination; when the completed oxygen supply in the medical oxygen process status is inconsistent with the actual output record of the oxygen supply network, the completed oxygen supply is corrected by the actual output record of the oxygen supply network; when the by-product hydrogen process status is missing, the by-product hydrogen process record of the most recent valid period is read as the substitute input and a status supplementation flag is written. Subsequently, to determine whether the remaining time period still meets the conditions for completing oxygen supply according to the original execution path, a correspondence determination is performed between the remaining target oxygen production demand and the remaining continuous oxygen production permit range, and an adjustment instruction is generated when a gap exists. The input quantities include the remaining target oxygen production demand, the remaining continuous oxygen production permit range, the amount of by-product hydrogen generated per unit of oxygen production, the status of the currently available hydrogen consumption channels, and the current operating status of multiple oxygen production units. Among them, the current operating status of multiple oxygen production units includes at least whether they are currently running, the current continuous running time, and whether they are currently allowed to continue running. The processing actions include: firstly, performing a correspondence determination between the remaining target oxygen production demand and the remaining continuous oxygen production permit range according to the unified time caliber of the remaining time period; when the remaining target oxygen production demand falls within the remaining continuous oxygen production permit range, the corresponding difference is recorded as zero, and the current execution path for the remaining time period remains unchanged; when the remaining target oxygen production demand exceeds the remaining continuous oxygen production permit range, the excess part is determined as the corresponding difference result, and the pre-consumption amount corresponding to the remaining time period is calculated based on the corresponding difference result and the amount of by-product hydrogen generated per unit of oxygen production. After obtaining the pre-consumption capacity, a pre-consumption adjustment instruction is generated based on the current status of the available hydrogen consumption channels. Simultaneously, based on the segmental demand results for the remaining time period, the current operating status of each oxygen production unit, and the remaining continuous oxygen production allowance, the oxygen production unit combination screening is re-executed to generate an oxygen production unit reorganization result, and further, an oxygen production execution adjustment instruction is generated. The output includes the pre-consumption adjustment instruction and the oxygen production execution adjustment instruction corresponding to the remaining time period, which are written into the pre-consumption adjustment record and the execution adjustment record respectively for subsequent reading during the execution process of the remaining time period. When all available hydrogen consumption channels are in an unavailable state, the pre-consumption adjustment instruction is marked as restricted, and the oxygen production execution adjustment instruction simultaneously compresses the oxygen production unit call range and oxygen production load capacity for the remaining time period. Finally, to ensure that the remaining time period returns to the permitted coverage state after adjustment, the pre-consumption adjustment command and the oxygen production execution adjustment command are iteratively implemented and covered. The inputs include the pre-consumption adjustment command, the oxygen production execution adjustment command, the current hydrogen storage status, the start time of the remaining time period, and the oxygen supply duration corresponding to the remaining time period. The processing actions include: first, controlling the hydrogen consumption unit to perform the corresponding pre-consumption processing within the remaining time period or the operable window before the start of the remaining time period according to the pre-consumption adjustment command, and updating the current hydrogen storage status after each pre-consumption processing; then, based on the updated current hydrogen storage status and the oxygen production execution adjustment command, redetermining the target oxygen production execution plan corresponding to the remaining time period, and using the previous oxygen production unit combination solution and timing arrangement rules for redetermining the process, and reconstructing the start time, load sharing ratio, and continuous running duration of each oxygen production unit in the remaining time period. Subsequently, after each reconstruction, the remaining continuous oxygen production permit range is recalculated and its correspondence with the remaining target oxygen production demand is re-evaluated. When the reconstructed remaining continuous oxygen production permit range covers the remaining target oxygen production demand, the current iteration is terminated and the iteration adjustment result is output. When the reconstructed remaining continuous oxygen production permit range still does not cover the remaining target oxygen production demand, the pre-consumption processing and target oxygen production execution scheme reconstruction continue until the remaining continuous oxygen production permit range covers the remaining target oxygen production demand and the medical oxygen supply output corresponding to the target oxygen supply period is completed. The output is the iteration adjustment result corresponding to the completion of medical oxygen supply output, and this result is written into the iteration adjustment record for archiving and reading after the end of the entire target oxygen supply period. When the oxygen unit recombination result is empty after a certain round of reconstruction, the oxygen unit combination that still meets the conditions for continued operation in the previous round is read as the backup execution combination, and the remaining target oxygen production demand is marked with a restricted output to avoid the reconstruction process losing its execution basis. Through the above processing, the remaining demand results and the remaining continuous oxygen production permit range are first reconstructed from the medical oxygen process status and the by-product hydrogen process status. Then, the correspondence between the remaining target oxygen production demand and the remaining continuous oxygen production permit range determines whether it is necessary to continue pre-consumption and reorganize the oxygen production unit. Finally, the iterative adjustment corresponding to the remaining time period is completed according to the pre-consumption adjustment instruction and the oxygen production execution adjustment instruction. This ensures that the subsequent part of the target oxygen supply period is always based on the current actual execution status and the actual hydrogen storage status, rather than continuing to use the static scheme at the beginning. After this processing, a rolling process is formed between the previous execution results, the current hydrogen storage status, the remaining by-product hydrogen acceptance capacity, and the remaining oxygen production execution scheme. The subsequent oxygen supply process can continue to maintain a unified permit range constraint and execution caliber after the status changes. In practical applications: When a hospital's four-hour oxygen supply period has reached the end of the second hour, and the medical oxygen process status indicates that the completed oxygen supply is lower than the planned value, and the by-product hydrogen process status indicates that there is unused incremental oxygen supply in the current period, the remaining target oxygen production demand for the next two hours is calculated by deducting the completed portion based on the total oxygen supply demand and total duration. Then, the remaining continuous oxygen production allowance is recalculated based on the current hydrogen storage status and the current capacity of the consumption channels. If it is found that the remaining target oxygen production demand for the next two hours exceeds the remaining continuous oxygen production allowance, the corresponding pre-consumption amount is further calculated. Based on the currently available hydrogen consumption channels and the current operating status of multiple oxygen production units, pre-consumption adjustment instructions and oxygen production execution adjustment instructions are generated. Subsequently, pre-consumption is executed within the operable window before or after the start of the next two hours, and the target oxygen production execution plan for the remaining period is rearranged until the remaining continuous oxygen production allowance covers the remaining target oxygen production demand. Finally, the remaining oxygen supply output is completed according to the updated plan.

[0022] The working principle of this scheme is as follows: First, based on the target oxygen supply volume and duration during the target oxygen supply period, the corresponding target oxygen production demand is calculated, and then the demand for additional by-product hydrogen that will be generated simultaneously during the oxygen supply process is further calculated. Then, combined with the current hydrogen storage volume, hydrogen storage safety boundary, and hydrogen absorption capacity during the target oxygen supply period, the continuous oxygen production permit range that the hydrogen storage unit can continuously accept during the period is calculated. If the target oxygen production demand exceeds the continuous oxygen production permit range, pre-absorption processing is performed before the start of the target oxygen supply period to release some of the stored hydrogen in advance to free up space for subsequent by-product hydrogen acceptance. Based on this, and according to the updated continuous oxygen production permit range, a target oxygen production unit combination is determined from multiple oxygen production units, and the start-up time, load sharing ratio, and continuous running time of each oxygen production unit are arranged to form a target oxygen production execution plan. During the execution, real-time oxygen production, real-time by-product hydrogen generation, and real-time hydrogen consumption are collected simultaneously, and the medical oxygen process status and by-product hydrogen process status are continuously calculated. If it is found that the continuous oxygen production permit range corresponding to the remaining time period is insufficient after execution, the pre-consumption adjustment and oxygen production execution reconstruction are triggered again until the medical oxygen supply output for the entire target oxygen supply period is completed. For example, during a two-hour period of increased oxygen supply at a hospital at night, the system first calculates the additional oxygen production required for those two hours based on the increased oxygen supply command issued by the main oxygen supply pipeline, and how much additional hydrogen byproduct this increased oxygen production will generate. Then, it reads how much hydrogen is currently stored in the hydrogen storage unit, how much more hydrogen can be absorbed, and how much hydrogen fuel cells or other hydrogen consumption pathways can absorb during those two hours. This determines whether the existing hydrogen storage and absorption conditions are sufficient to support continuous oxygen production for those two hours. If insufficient, the system releases a portion of the stored hydrogen before the official increased oxygen supply begins. Then, it schedules which oxygen production units to start first, which to add later, and how much oxygen production load each unit will bear. During operation, the system supplies oxygen while simultaneously checking whether the generation and absorption of byproduct hydrogen are balanced. If, due to a decrease in absorption capacity or an increase in hydrogen storage occupancy, continued oxygen production in subsequent periods becomes limited, the system immediately recalculates the permissible range for the remaining periods and rearranges the operation modes of the pre-absorption and oxygen production units, thereby ensuring continuous oxygen supply to the hospital throughout the entire oxygen usage process.
