Description

Technical Field

[0001] This application belongs to the field of hydrogen technology, and in particular relates to a hydrogen early warning method, device, terminal equipment and storage medium. Background Technology

[0002] Hydrogen energy boasts abundant resources, is green and low-carbon, and has wide applications, making it a primary industrial raw material used in various chemical fields. Under normal temperature and pressure, hydrogen gas is generally quite stable. However, in a confined space, if the volume fraction of hydrogen in the air is between 4% and 75%, it can cause an explosion upon contact with a source of ignition. Therefore, it is necessary to monitor the hydrogen concentration in confined spaces.

[0003] Current methods typically involve deploying numerous hydrogen detection devices in a confined space to monitor hydrogen concentration and issuing warnings when the concentration is too high. Alternatively, warnings can be issued manually based on personnel monitoring and recording.

[0004] However, when early warnings are issued based on hydrogen detection equipment, a serious hydrogen leak may have already occurred in the confined space. Furthermore, manual early warning methods are costly and susceptible to issues such as low safety awareness and negligence in supervision, leading to significant uncertainty regarding hydrogen concentration in confined spaces.

[0005] Therefore, the existing technology for early warning of changes in hydrogen concentration is unreasonable and has poor early warning effect. Summary of the Invention

[0028] To monitor and issue early warnings about hydrogen concentration in confined spaces, existing methods typically involve deploying numerous hydrogen detection devices within the space to monitor hydrogen concentration and issuing warnings when the concentration is too high. Alternatively, warnings can be issued manually based on personnel monitoring and recording.

[0029] However, when early warnings are issued based on hydrogen detection equipment, a serious hydrogen leak may have already occurred in the confined space. Furthermore, manual early warning methods are costly and susceptible to issues such as low safety awareness and negligence in supervision, leading to significant uncertainty regarding hydrogen concentration in confined spaces.

[0030] Based on this, in order to reasonably provide early warning of changes in hydrogen concentration, this application provides a hydrogen early warning method. This hydrogen early warning method can be applied to terminal devices such as tablet computers, laptops, ultra-mobile personal computers (UMPCs), and netbooks, or to detection devices such as hydrogen detectors. This application does not impose any restrictions on the specific type of terminal device.

[0031] Please see Figure 1 , Figure 1 The following is a flowchart illustrating the implementation of a hydrogen early warning method according to an embodiment of this application. The method includes the following steps:

[0032] S101. Obtain multiple historical hydrogen concentrations when detecting a preset monitoring area within the target time period.

[0033] In one embodiment, the monitoring area can be the area where a hydrogen storage device is located. Within a monitoring area, one or more detection devices for monitoring hydrogen concentration can be installed. Furthermore, the model of each detection device can be the same or different; there is no limitation on this.

[0034] The detection equipment includes, but is not limited to, portable hydrogen detectors, pump-type hydrogen detectors, and online hydrogen detectors.

[0035] It should be noted that when there are multiple detection devices, multiple hydrogen concentrations can be detected simultaneously at any given time. In this case, the terminal device can determine the average value of the multiple hydrogen concentrations as the final hydrogen concentration at that moment.

[0036] The target time period can be set in advance by staff or determined based on historical hydrogen concentrations at historical moments; there are no restrictions on this.

[0037] For example, when implementing the hydrogen warning method in this instance, if the hydrogen concentration in the monitored area is too high, for example, if the hydrogen concentration exceeds the preset warning value, the terminal device will generate a warning message and send it to a pre-set warning terminal. At this time, when staff confirm receipt of the warning message based on the warning terminal, they will typically inspect and repair the storage devices in the monitored area to check for leaks. Simultaneously, they will reduce the hydrogen concentration in the monitored area. For example, this can be done through ventilation to prevent the long-term accumulation of hydrogen in the confined space.

[0038] Based on this, when selecting a target time period, the terminal device can first determine the two most recent target times before the current time. The historical hydrogen concentration corresponding to each target time is greater than the preset warning value. That is, the times when two warning messages are generated are selected. After the first warning message is generated, staff will inspect and repair the storage devices in the monitored area, reducing the hydrogen concentration in the monitored area. Therefore, at each time point after the first warning message is generated, the hydrogen concentration detected by the detection device can generally be considered to represent the normal change in hydrogen concentration in the monitored area when an undamaged storage device (without a leakage event) is operating.

[0039] Subsequently, when a second warning message is generated, it can be assumed that the storage device may be leaking, causing the hydrogen concentration in the monitored area to exceed the preset warning value. Therefore, at each time point between the first and second warning message generation, the hydrogen concentration detected by the detection device can generally characterize the normal changes in hydrogen concentration in the monitored area when the undamaged storage device is operating, and the abnormal changes in hydrogen concentration in the monitored area when a leak occurs in the undamaged storage device.

[0040] Understandably, defining the time interval between two target moments as the target time interval and obtaining multiple historical hydrogen concentrations within that time interval can characterize not only the hydrogen concentration changes when the storage device is functioning normally, but also the hydrogen concentration changes when the storage device gradually malfunctions (gradually experiencing leakage events). Based on this, it can be assumed that multiple historical hydrogen concentrations within the target time interval can be used to predict whether a leakage event will occur in the storage device in subsequent time intervals.

[0041] There may be multiple historical moments when the hydrogen concentration exceeds the preset warning value. In this embodiment, the two moments closest to the current moment are selected as the target moments. This improves the accuracy of subsequent predictions.

[0042] It should be noted that selecting the two target time periods closest to the current time is only one example in this embodiment. In other embodiments, the target time periods can be selected randomly, and there is no limitation on this.

[0043] In another embodiment, if the time interval between two target times is less than a preset interval, the times of the two warnings can be considered close. In this case, the accuracy of using the time interval between the two target times for subsequent predictions may be low. Therefore, the latest target time (closest to the current time) can be retained, and another target time closest to the current time can be re-determined in chronological order, until the time interval between the target time and the latest target time is again determined to be greater than or equal to the preset interval.

[0044] For example, given target time A and target time B, target time A is earlier than target time B (i.e., target time B is closer to the current time). If the time interval between target time A and target time B is less than a preset interval, the latest target time B can be retained. Simultaneously, another target time C, which is closest to the current time, is determined. Then, if the time interval between target time C and target time B is greater than or equal to the preset interval, that time interval is determined as the target time interval.

[0045] S102. Generate hydrogen concentration variation curves based on historical hydrogen concentrations.

[0046] In one embodiment, the aforementioned change curve is a curve generated based on historical hydrogen concentration, which can be used to characterize the change in hydrogen concentration when the storage device is normal, and the change in hydrogen concentration when the storage device gradually malfunctions (gradually experiencing leakage events).

[0047] The variation curve can be generated based on regression analysis or graph correlation analysis. In this embodiment, the method of generating the variation curve is not limited. For example, the variation curve can be a curve generated based on the time difference and historical hydrogen concentration. The time difference can be the difference between the historical time corresponding to the historical hydrogen concentration and the earliest target time in the target time period.

[0048] It should be noted that, in order to generate a change curve that reflects actual conditions, the historical hydrogen concentration data within the target time period should be greater than a preset value. Therefore, if the historical hydrogen concentration data is less than the preset value, the terminal device can select two other target times as the target time period.

[0049] The detection equipment can monitor hydrogen concentration at preset intervals. Therefore, the expected interval for collecting a preset amount of hydrogen concentration can be predetermined. Based on this, if the duration between the two most recent target times is less than the expected interval, two other target times can be selected as the target time period. Otherwise, if the duration between the two most recent target times is greater than or equal to the expected interval, it can be directly determined as the target time period.

[0050] S103. Obtain the actual hydrogen concentration at the current moment.

[0051] In one embodiment, the actual hydrogen concentration at the current moment can be determined by the detection device described above, and then uploaded to the terminal device by the detection device, which will not be described in detail.

[0052] S104. If the actual hydrogen concentration is determined to meet the preset warning conditions based on the change curve, then a warning message is generated.

[0053] In one embodiment, the aforementioned variation curve can characterize the hydrogen concentration change when the storage device is normal, and the hydrogen concentration change when the storage device gradually malfunctions (gradually experiencing a leakage event). Therefore, based on the actual hydrogen concentration at the current moment, it can be determined whether the current actual hydrogen concentration meets preset prediction conditions, such as whether it meets the hydrogen concentration change conditions when the storage device gradually experiences a leakage event, in order to determine whether to issue an early warning.

[0054] Specifically, the terminal device can predict the hydrogen concentration at various times after the target time period based on the change curve. Then, it determines the target predicted hydrogen concentration for the current time from multiple predicted hydrogen concentrations. Finally, based on the target predicted hydrogen concentration and the actual hydrogen concentration, it generates a warning result corresponding to the warning conditions.

[0055] In one embodiment, since the variation curve is generated based on the time difference and historical hydrogen concentration, when predicting the hydrogen concentration at the current moment, the difference between the current moment and the latest target moment in the target time period can be calculated. Then, the difference is substituted into the variation curve to determine the target predicted hydrogen concentration corresponding to that difference. In this embodiment, the method for obtaining the predicted hydrogen concentration at the current moment based on the variation curve is not limited.

[0056] In one specific embodiment, the terminal device can calculate the concentration difference between the actual hydrogen concentration and the target predicted hydrogen concentration. Then, when the actual hydrogen concentration is greater than the target predicted hydrogen concentration and the concentration difference is greater than a first preset concentration difference, the warning result is determined to be that the actual hydrogen concentration meets the preset warning condition.

[0057] Specifically, when the actual hydrogen concentration exceeds the target predicted hydrogen concentration, the terminal device can assume that the hydrogen concentration change within the monitored area from the last target time period to the current time exceeds expectations. Therefore, it can be assumed that a leakage event may have occurred in the storage device, and the warning result can be determined as the actual hydrogen concentration meeting the preset warning conditions.

[0058] However, in practice, the actual hydrogen concentration obtained by the detection equipment may contain errors. Therefore, to determine whether the warning conditions are met, it is necessary to further calculate the concentration difference between the actual hydrogen concentration and the target predicted hydrogen concentration. Only when the concentration difference is also greater than the first preset concentration difference can it be determined that the warning conditions are met.

[0059] The first preset concentration difference can be set according to the actual situation, and there is no limitation on it.

[0060] It should be noted that when the actual hydrogen concentration is greater than the target predicted hydrogen concentration, it can be assumed that the change in hydrogen concentration between the last target moment and the current moment within the monitored area exceeds expectations. However, because the concentration difference is less than or equal to the first preset concentration difference, the terminal equipment usually cannot accurately determine whether the actual hydrogen concentration being greater than the target predicted hydrogen concentration is due to a misreading by the detection equipment or a potential leakage event in the storage device.

[0061] Based on this, the terminal device can determine the estimated time it will take for the actual hydrogen concentration to reach the preset warning value according to the change curve. Then, if the estimated time is less than the preset time, the warning result is determined to be that the actual hydrogen concentration meets the preset warning condition. That is, it is determined that the above-mentioned actual hydrogen concentration exceeding the target predicted hydrogen concentration is caused by a leakage event in the storage device. Therefore, the terminal device needs to generate warning information and send it to the warning terminal.

[0062] The preset duration can be set according to the actual situation, and there is no limitation on it.

[0063] It should be noted that the variation curve is generated based on the time difference and historical hydrogen concentration. The time difference can be the difference between the historical time corresponding to the historical hydrogen concentration and the earliest target time within the target time period. Therefore, the terminal device can use the actual hydrogen concentration as input and perform inverse calculations based on the variation curve to obtain the corresponding target historical time within the historical time period. Then, the difference between the target historical time and the last target time within the target time period is determined as the estimated duration.

[0064] Correspondingly, when the actual hydrogen concentration is less than or equal to the target predicted hydrogen concentration, or the expected duration is greater than or equal to the preset duration, the terminal device can determine that the warning result is that the actual hydrogen concentration does not meet the preset warning conditions. At this time, the terminal device can determine that the hydrogen concentration within the monitoring range meets the requirements, and only needs to prepare to obtain the actual hydrogen concentration at the next moment for issuing the warning.

[0065] The aforementioned warning information may include, but is not limited to, one or more pieces of information such as actual hydrogen concentration, current time, or expected duration.

[0066] It should be noted that, in another embodiment, if the concentration difference between the actual hydrogen concentration and the preset warning value is less than a second preset concentration difference, the terminal device can assume that the actual hydrogen concentration in the monitored area has become high over time, potentially posing a safety hazard. Based on this, the terminal device can directly generate a warning message to alert staff in advance and eliminate potential safety hazards.

[0067] In this embodiment, multiple historical hydrogen concentrations are obtained when a preset monitoring area is monitored within a target time period to generate a change curve characterizing the hydrogen concentration changes in the monitoring area within the target time period. Then, the actual hydrogen concentration at the current time is obtained, and when the actual hydrogen concentration meets preset warning conditions based on the generated hydrogen concentration change curve, a warning message can be generated to provide early warning to the monitoring area and reduce safety risks.

[0068] In another embodiment, as described above, the terminal device can predict the hydrogen concentration at each time point after the target time period based on the change curve. Furthermore, the terminal device can compare each predicted hydrogen concentration with the corresponding actual hydrogen concentration. If a preset number of consecutive actual hydrogen concentrations exceed the predicted hydrogen concentration, the terminal device can directly generate an early warning message.

[0069] It is understandable that, for any actual hydrogen concentration, although the actual hydrogen concentration is greater than the target predicted hydrogen concentration at that time, there may be a situation where the concentration difference between the actual hydrogen concentration and the target predicted hydrogen concentration at the corresponding time is less than the first preset concentration difference, and the expected duration for the actual hydrogen concentration to reach the preset warning value is greater than or equal to the preset duration, as determined by the change curve.

[0070] However, if the actual hydrogen concentration is consistently higher than the predicted hydrogen concentration for a predetermined number of consecutive periods, the terminal device can also assume that the actual change in hydrogen concentration within the confined space is greater than the historical changes in hydrogen concentration over the target time period. Based on this, in this situation, the terminal device can also generate an early warning message to improve the accuracy of early warnings for confined spaces.

[0071] Understandably, if the actual hydrogen concentration for a consecutive preset number of times is less than or equal to the predicted hydrogen concentration, the terminal device may not need to perform any operation.

[0072] The preset quantity can be set according to actual needs and is not limited. For example, the preset quantity can be 3 or 5.
