[0053] In the embodiment of the present disclosure and other possible embodiments, the storage device 51 is used to store hydrogen storage density standard curve templates corresponding to different internal pressures and different internal temperatures. The processor 52 calls the hydrogen storage density standard curve template in the storage device 51 and determines the hydrogen storage density within the hydrogen storage mechanism 1 at the internal pressure and the internal temperature based on the hydrogen storage density standard curve template.

[0060] Figure 3 FIG. 1 shows a schematic structural diagram of a hydrogen storage control system according to an embodiment of the present disclosure. Figure 3 As shown, the hydrogen reserve control system includes: the hydrogen storage detection device as mentioned above; the hydrogen storage mechanism 1 is connected to the gas supply mechanism; wherein, the gas supply mechanism is used to supply hydrogen to the interior of the hydrogen storage mechanism 1; the controller 5 is connected to the gas supply mechanism; wherein, the storage 51 in the controller 5 is used to store the upper limit threshold and the lower limit threshold of the reserve amount corresponding to the hydrogen storage mechanism 1; the processor 52 in the controller 5 is used to control the gas supply mechanism connected to the hydrogen storage mechanism 1 to supply gas to the hydrogen storage mechanism 1 or stop supplying gas based on the remaining hydrogen storage amount in the hydrogen storage mechanism 1, the upper limit threshold and the lower limit threshold.

[0061] In the embodiments of the present disclosure and other possible embodiments, the processor 52 in the controller 5 is configured with a comparator; the comparator is used to control the gas supply mechanism connected to the hydrogen storage mechanism 1 to supply gas or stop supplying gas to the hydrogen storage mechanism 1 based on the remaining hydrogen storage amount in the hydrogen storage mechanism 1, the upper limit threshold and the lower limit threshold.

[0062] For example, in the embodiments of the present disclosure and other possible embodiments, as the gas supply mechanism supplies hydrogen to the interior of the hydrogen storage mechanism 1, the reserve amount (remaining hydrogen storage amount) corresponding to the hydrogen storage mechanism 1 gradually increases; however, the reserve amount (remaining hydrogen storage amount) corresponding to the hydrogen storage mechanism 1 should be between the upper limit threshold and the lower limit threshold, and must not exceed the upper limit threshold; when the reserve amount (remaining hydrogen storage amount) corresponding to the hydrogen storage mechanism 1 exceeds the upper limit threshold, the gas supply mechanism connected to the hydrogen storage mechanism 1 is controlled to stop supplying gas to the hydrogen storage mechanism 1; when the reserve amount (remaining hydrogen storage amount) corresponding to the hydrogen storage mechanism 1 is less than the upper limit threshold, the gas supply mechanism connected to the hydrogen storage mechanism 1 is controlled to start supplying gas to the hydrogen storage mechanism 1.

[0063] In an embodiment of the present disclosure, the hydrogen reserve control system further includes: a calculator or a calculator set in the controller 5 or a calculator set in the processor 52 of the controller 5; wherein the input mechanism 53 connected to the controller 5 is used to input the historical hydrogen discharge amount or the remaining hydrogen storage amount corresponding to the hydrogen storage mechanism 1; the calculator is used to determine the upper limit threshold and the lower limit threshold based on the historical hydrogen discharge amount or the remaining hydrogen storage amount corresponding to the hydrogen storage mechanism 1. The values ​​corresponding to the upper limit threshold and the lower limit threshold are different in different seasons and / or different hydrogen consumption peak periods.

[0064] For example, in the embodiment of the present disclosure and other possible embodiments, the average value of hydrogen consumption is calculated based on the historical hydrogen discharge or remaining hydrogen storage corresponding to the hydrogen storage mechanism 1. and standard deviation σ. For example, during a winter peak demand period (a type of hydrogen peak period), the average daily hydrogen consumption of a hydrogen refueling station is 500kg, with a standard deviation of 50kg. Based on these data, the system dynamically adjusts the upper and lower thresholds of the reserve capacity, where the lower threshold is Can be set to − 1.5⋅σ=500−1.5×50=425kg, upper threshold Can be set to + 2⋅σ=500+2×50=600kg.

[0065] For example, in the embodiments of the present disclosure and other possible embodiments, the hydrogen reserve control system will determine whether replenishment is needed based on the upper threshold and the lower threshold, combined with the real-time hydrogen consumption of the hydrogen refueling station. When the reserve (remaining hydrogen storage) is lower than the lower threshold of 425kg, the hydrogen reserve control system automatically triggers the replenishment process to replenish the hydrogen reserve to a safe level of the upper threshold of 600kg. In this process, the mechanism of dynamically adjusting the threshold can flexibly adapt to fluctuations in market demand. For example, in the summer when hydrogen demand is low (a type of hydrogen peak period), the system will recalculate the new threshold based on the summer hydrogen consumption data, and may adjust the lower threshold to 350kg and the upper threshold to 500kg to avoid unnecessary excessive reserves and reduce capital and storage usage.

[0066] In an embodiment of the present disclosure, the hydrogen reserve control system further includes: an alarm mechanism 9 connected to the controller 5; wherein the controller 5 is used to provide a hydrogen refill prompt through the alarm mechanism 9 based on the remaining hydrogen storage amount and the set limit in the hydrogen storage mechanism 1.

[0067] In the embodiment of the present disclosure and other possible embodiments, the alarm mechanism 9 may be configured as an electronic device, such as a mobile phone, a terminal computer, a digital broadcast terminal, a messaging device, a tablet device, a personal digital assistant, etc.

[0068] In the disclosed embodiments and other possible embodiments, the hydrogen reserve control system monitors changes in hydrogen reserves and consumption and sets warning thresholds (set limits). When hydrogen reserves approach the lower threshold—for example, when reserves drop to 430 kg during peak winter demand—the hydrogen reserve control system issues a preemptive alarm, using the alarm mechanism 9 to alert operators to restock. This early warning mechanism effectively prevents supply interruptions caused by insufficient reserves and improves the safety of the hydrogen reserve control system.

[0069] In an embodiment of the present disclosure, the hydrogen reserve control system further includes: a timer connected to the controller 5 or a timer set in the controller 5 or a timer set in the processor 52 of the controller 5; wherein the timer is used to time the storage time of hydrogen in the hydrogen storage mechanism 1; the controller 5 is used to update the remaining hydrogen storage amount in the hydrogen storage mechanism 1 according to the storage time and the set time.

[0070] In the disclosed embodiment and other possible embodiments, the controller 5 or the processor 52 of the controller 5 of the hydrogen reserve control system periodically performs inventory operations. For example, if the set time is set to one week, the inventory operation is performed once a week. During the inventory operation, the pressure detection component 2 and the temperature detection component 3 re-collect the hydrogen station's reserve level and compare it with the set upper and lower thresholds. If the hydrogen reserve control system detects that the reserve level is 400 kg (below the lower threshold of 425 kg) during the inventory operation, the alarm mechanism 9 is triggered and replenishment arrangements are initiated. This automated process can be completed without human intervention, ensuring timely replenishment.

[0071] In an embodiment of the present disclosure, the gas supply mechanism includes at least: one or more of a gas supply transport vehicle 7 and a local gas supply tank 8; wherein the gas supply unit of the gas supply transport vehicle 7 is connected to the interior of the hydrogen storage mechanism 1 through a second pipeline 1b; the local gas supply tank 8 is connected to the interior of the hydrogen storage mechanism 1 through a third pipeline 1e.

[0074] In the embodiments of the present disclosure and other possible embodiments, a first gas supply assembly 1a is further provided between the second pipeline 1b and the hydrogen storage mechanism 1; wherein, the first gas supply assembly 1a includes: a first gas supply body 1a-1 and a first gas supply connector 1a-2 provided on one side of the first gas supply body 1a-1; a second flow channel is provided in the first gas supply body 1a-1, one end of the second flow channel is connected to the second pipeline 1b, and the other end of the second flow channel is provided with the first gas supply connector 1a-2.

[0077] In the disclosed embodiment and other possible embodiments, the controller 5 or its processor 52 automatically determines the required hydrogen replenishment amount and the optimal replenishment time based on real-time monitoring data and inventory results. For example, if the current reserve (remaining reserve) is 400 kg and the upper limit is 600 kg, the hydrogen reserve control system will calculate that the required hydrogen replenishment amount is 200 kg and schedule the earliest possible delivery based on the availability of transport vehicles (gas supply transport vehicles 7) and the needs of other hydrogen refueling stations. If it is peak season, the controller 5 or its processor 52 may prioritize replenishment operations within a shorter timeframe, or even directly replenish hydrogen through the hydrogen refueling station's local gas supply pipeline (local gas supply tank 8), thereby shortening transportation time.
