[0029] See also Figure 1 , Figure 11 is a flow chart of a fault monitoring method based on a low-voltage power distribution system provided in an embodiment of the present application. In this embodiment, the execution subject of the fault monitoring method is a terminal device. It is understandable that the types of terminal devices include but are not limited to mobile phones, tablet computers, laptop computers, ultra-mobile personal computers (Ultra-Mobile Personal Computer, UMPC), netbooks, personal digital assistants (Personal Digital Assistant, PDA), etc., and the embodiments of the present application do not impose any restrictions on the specific types of terminal devices.
[0030] See also Figure 1 The fault monitoring method provided in the embodiment of the present application includes but is not limited to the following steps:
[0031] In S100, in response to the hydrogen production end instruction, the current cumulative power consumption information and hydrogen production amount information of the target electrolytic cell are obtained.
[0032] Specifically, the terminal device can first respond to the hydrogen preparation end instruction, obtain the hydrogen preparation amount information of the target electrolyzer based on the preset gas flow meter, and at the same time obtain the current cumulative power consumption information of the target electrolyzer based on the low-voltage power distribution system connected to the target electrolyzer, wherein the hydrogen preparation end instruction is used to describe the feedback instruction generated by the target electrolyzer to end the hydrogen preparation task; the target electrolyzer is used to describe the PEM electrolyzer or alkaline electrolyzer monitored in real time; the current cumulative power consumption information is used to describe the power consumption of the target electrolyzer in this hydrogen preparation task; and the hydrogen preparation amount information is used to describe the amount of hydrogen prepared by the target electrolyzer in this hydrogen preparation task.
[0033] In S200, target cumulative power consumption information of the target electrolytic cell is obtained based on the hydrogen production amount information and a preset historical database.
[0034] Specifically, after the terminal device obtains the current cumulative power consumption information and hydrogen production information, the terminal device can quickly obtain the target cumulative power consumption information of the target electrolyzer based on the hydrogen production information and a preset historical database.
[0035] In some possible implementations, in order to quickly obtain the target cumulative power consumption information of the target electrolytic cell, please refer to Figure 2 Step S200 includes but is not limited to the following steps:
[0036] In S210, the historical database is searched based on the hydrogen production amount information to obtain the preliminary power consumption information.
[0037] Specifically, the terminal device can first search the historical database based on the hydrogen preparation quantity information, and obtain the preliminary power consumption information from the historical database, wherein the historical database stores multiple historical preparation quantity information, and the historical database also stores the historical cumulative power consumption information corresponding to each historical preparation quantity information; the preliminary power consumption information is used to describe the historical cumulative power consumption information corresponding to the historical preparation quantity information that is equal to the current cumulative power consumption information.
[0038] Exemplarily, the terminal device may first determine the historical preparation quantity information in the historical database that is equal to the current cumulative power consumption information, and then determine the historical cumulative power consumption information corresponding to the historical preparation quantity information.
[0039] It should be noted that, when there is no historical preparation quantity information equal to the current cumulative power consumption information in the historical database, the terminal device can determine the historical preparation quantity information whose value is closest to the current cumulative power consumption information as the determination object.
[0040] In S220 , it is determined whether the number of the initially selected power consumption information is plural.
[0041] Specifically, after the terminal device obtains the preliminary selected power consumption information, the terminal device may determine whether the number of the preliminary selected power consumption information is multiple.
[0042] In S230 , if there are multiple pieces of preliminary selected power consumption information, the preliminary selected power consumption information with the shortest difference time is determined as the target cumulative power consumption information; otherwise, the preliminary selected power consumption information is determined as the target cumulative power consumption information.
[0043] Specifically, if there are multiple preliminary power consumption information, the terminal device can determine the preliminary power consumption information with the shortest gap time as the target cumulative power consumption information, where the gap time is used to describe the interval time between the preliminary power consumption information and the response time of the hydrogen preparation end instruction.
[0044] Without loss of generality, if the number of the preliminary selected power consumption information is only one, the terminal device can directly determine the preliminary selected power consumption information as the target cumulative power consumption information.
[0045] In S300 , fault detection result information is generated based on the current cumulative power consumption information and the target cumulative power consumption information.
[0046] Specifically, after the terminal device determines the target cumulative power consumption information of the target electrolyzer, the terminal device can promptly generate fault detection result information based on the current cumulative power consumption information and the target cumulative power consumption information, thereby achieving timely fault detection and processing after the target electrolyzer completes the hydrogen preparation task, thereby improving the real-time performance of fault monitoring.
[0047] In some possible implementations, in order to generate effective fault detection result information, please refer to Figure 3 Step S300 includes but is not limited to the following steps:
[0048] In S310, power consumption abnormal increase value information is generated based on the difference between the current cumulative power consumption information and the target cumulative power consumption information.
[0049] Without loss of generality, as the use time of the target electrolytic cell increases, the components inside the target electrolytic cell may experience excessive aging and other faults, resulting in an abnormal increase in power consumption.
[0050] Specifically, the terminal device can generate abnormal power consumption growth value information based on the difference between the current cumulative power consumption information and the target cumulative power consumption information, wherein the abnormal power consumption growth value information is the difference between the current cumulative power consumption information and the target cumulative power consumption information.
[0051] In S320, the abnormal growth value information of power consumption is compared with the preset reasonable growth value information.
[0052] Specifically, after the terminal device generates abnormal power consumption growth value information, the terminal device can compare the abnormal power consumption growth value information with the preset reasonable growth value information, wherein the reasonable growth value information is used to describe the power consumption growth value of the target electrolytic cell that meets the production requirements as the usage time increases. The reasonable growth value information can be customized by production personnel according to production requirements.
[0053] In S330, if the abnormal increase value information of power consumption is greater than the reasonable increase value information, the increase difference information is generated according to the difference between the abnormal increase value information of power consumption and the reasonable increase value information.
[0054] Specifically, if the abnormal growth value information of power consumption is greater than the reasonable growth value information, the terminal device can generate growth difference information based on the difference between the abnormal growth value information of power consumption and the reasonable growth value information, wherein the growth difference information is the difference between the abnormal growth value information of power consumption and the reasonable growth value information.
[0055] In S340, the growth difference information is compared with the preset difference threshold information.
[0056] Specifically, after the terminal device generates the growth difference information, the terminal device may compare the growth difference information with the preset difference threshold information, wherein the difference threshold information may be customized by the production personnel according to the production requirements.
[0057] In S350, if the growth difference information is greater than the difference threshold information, severe fault information is generated, otherwise, mild fault information is generated.
[0058] Specifically, the fault detection result information includes minor fault information or major fault information. The minor fault information is used to describe the existence of a minor fault in the target electrolytic cell, and the major fault information is used to describe the existence of a major fault in the target electrolytic cell. If the growth difference information is greater than the difference threshold information, the terminal device can generate major fault information. If the growth difference information is less than or equal to the difference threshold information, the terminal device can generate minor fault information, thereby achieving real-time and accurate monitoring of the target electrolytic cell on the premise of measuring the actual working condition of the target electrolytic cell.
[0059] In some possible implementations, in order to facilitate iterative fault monitoring of the target electrolyzer in combination with big data, please refer to Figure 4 If the fault detection result information is severe fault information, then after step S300, the method further includes but is not limited to the following steps:
[0060] In S400, the current maximum current information, the maximum electrolyte concentration information and the current maximum operating temperature information of the target electrolytic cell are obtained.
[0061] Specifically, the terminal device can first obtain the current maximum current information of the target electrolyzer based on the low-voltage power distribution system connected to the target electrolyzer, and obtain the maximum electrolyte concentration information of the target electrolyzer based on a preset concentration sensor, and at the same time obtain the current maximum operating temperature information of the target electrolyzer based on a preset temperature sensor, wherein the current maximum current information is used to describe the maximum current of the target electrolyzer in this hydrogen preparation task; the maximum electrolyte concentration information is used to describe the maximum electrolyte concentration of the target electrolyzer in this hydrogen preparation task; and the current maximum operating temperature information is used to describe the highest operating temperature of the target electrolyzer in this hydrogen preparation task.
[0062] In S410, warning parameter set information is generated according to the current maximum current information, the maximum electrolyte concentration information and the current maximum operating temperature information.
[0063] Specifically, after the terminal device obtains the current maximum current information, the maximum electrolyte concentration information and the current maximum operating temperature information, the terminal device can comprehensively generate the warning parameter set information based on the current maximum current information, the maximum electrolyte concentration information and the current maximum operating temperature information, thereby classifying the current maximum current information, the maximum electrolyte concentration information and the current maximum operating temperature information into a warning parameter set, so as to facilitate the automatic generation of warning information when the corresponding parameters reach the current maximum current information, the maximum electrolyte concentration information and the current maximum operating temperature information again.
[0064] In some possible implementations, in order to facilitate production personnel to intuitively know the maintenance effect, please refer to Figure 5After step S410, the method further includes but is not limited to the following steps:
[0065] In S420, in response to the fault repair completion instruction, the hydrogen production end instruction is executed again to obtain the current cumulative power consumption information and hydrogen production information of the target electrolytic cell until the fault detection result information is generated based on the current cumulative power consumption information and the target cumulative power consumption information.
[0066] Specifically, the terminal device may execute the above steps S100 to S300 again in response to a fault repair completion instruction, wherein the fault repair completion instruction is used to describe the production personnel completing the fault repair task for the target electrolytic cell.
[0067] In S430, if the fault detection result information is light fault information or heavy fault information, fault repair failure information is generated.
[0068] Specifically, if the fault detection result information is again a minor fault information or a severe fault information, it indicates that the maintenance effect is not as expected, and the terminal device can generate fault repair failure information, where the fault repair failure information is used to describe the failure of the fault repair process for the target electrolytic cell and requires repair again.
[0069] The implementation principle of the fault monitoring method based on the low-voltage power distribution system in the embodiment of the present application is as follows: the terminal device can first respond to the hydrogen preparation end instruction, obtain the current cumulative power consumption information and hydrogen production information of the target electrolyzer, and then search the historical database according to the hydrogen production information to quickly obtain the target cumulative power consumption information of the target electrolyzer, and finally generate fault detection result information in real time according to the current cumulative power consumption information and the target cumulative power consumption information, so as to realize timely fault detection and processing of the target electrolyzer after the hydrogen preparation task is completed, thereby effectively improving the real-time performance of fault monitoring.
