The working principle and the beneficial effects of the technical scheme are as follows:
according to the application, event search conditions are introduced, emergency control events of the hydrogen production electrolytic cells possibly occurring on a plurality of hydrogen production electrolytic cells connected in parallel are searched in a targeted manner, a plurality of groups of operation problem monitoring templates and first emergency control strategies which are in one-to-one correspondence are determined, the operation problems of the hydrogen production electrolytic cells are monitored, technical staff are not required to be arranged to monitor the working process of the hydrogen production electrolytic cells, the labor cost is greatly reduced, the monitoring comprehensiveness is further improved, in addition, when the operation problems occur, the corresponding first emergency control strategies are timely adopted, and the timeliness of emergency control of the hydrogen production electrolytic cells with problems is greatly improved.

analyzing a content type set of the target event; the content types are listed with each content type of the target event in a centralized manner;
comparing the content type set with a preset standard content type set to obtain the missing content type of the target event; the standard content types are listed in a centralized way as one complete record of the content types which should be recorded by event records such as how to carry out emergency control on the historical operation problems of other hydrogen production electrolytic tanks, for example: historical operating problems, emergency control schemes, etc.; comparing the content type set with the standard content type set, namely determining which content type is missing in the target event, namely the missing content type;
determining interactive comments of a target event from an event search scene; after sharing a target event in an event searching scene, a sharing party (such as a person with parallel hydrogen production electrolytic cell operation monitoring and emergency control experience) carries out comments on the target event, and the sharing party replies the comments to generate interactive comments;
analyzing a plurality of dialogue items and corresponding dialogue time in the interactive comments;
based on the dialogue time, setting dialogue items on a preset time line; when setting, setting the dialogue item at the corresponding time node of the dialogue event on the time line;
determining a conversation item cluster formed by at least N consecutive conversation items from a timeline based on conversation item cluster conditions; n is an integer greater than or equal to 2;
adding dialogue items corresponding to the publisher of the target event in the dialogue item cluster into the target event; the dialogue item corresponding to the publisher of the target event in the dialogue item cluster contains the related content of the missing content type, and the dialogue item is completed after the target event is supplemented;
taking the target event as an emergency control event of the hydrogen production electrolytic cell;
wherein the event search formula condition includes:
the target weight sum is greater than or equal to a preset weight sum threshold; the target weight sum is the sum of the conditional weights of the event search conditions in the event search formula; the condition weight represents the extent to which the event search condition needs to be satisfied by the search results, such as: the event search condition is that the event should occur in other hydrogen production electrolytic cells with the model number Q2, and if the search result does not occur in other hydrogen production electrolytic cells with the model number Q2, the search result is completely unlikely to occur in the hydrogen production electrolytic cells, so the condition weight is larger; the weights and thresholds may be, for example: 120; when the event search formula condition is met, the degree that the event search formula overall needs to be met by search results is larger, and the possibility that search results occur on a hydrogen production electrolytic tank due to inaccurate search is avoided;
the target number is greater than or equal to a preset number threshold; the target number is the number of the conditional weights which are larger than or equal to a preset weight threshold value in the conditional weights; the weight threshold may be, for example: 15; the number threshold may be, for example: 6, preparing a base material;
the maximum condition weight and the minimum condition weight of the event search conditions in the event search type are larger than or equal to a preset weight difference threshold; the weight difference threshold may be, for example: 5, a step of; when the two event searching type conditions are met, more larger condition weights exist in the event searching type, so that the event searching conditions with larger condition weights are preferentially met by the searching results, and the searching rationality is improved;
wherein the conversation item cluster conditions include:
the first target semantics correspond to matched trigger dialogue semantics in a preset trigger dialogue semantics library corresponding to the missing content type; the first target dialogue semantics are first dialogue semantics of the dialogue items which are ranked first in the dialogue item cluster; triggering dialog semantics are semantics that represent that a dialog is about to produce missing content type related content, such as: the type of the missing content is an emergency control strategy which is lack of execution after the operation problem of the hydrogen production electrolytic tank occurs, and the trigger dialogue semantics are 'how to perform emergency control on the hydrogen production electrolytic tank subsequently';
the second target semantics correspond to matched dialog ending semantics in a preset dialog ending semantics library; the second target semantics are second dialog semantics of the dialog item of which the last bit is ordered in the dialog item cluster. Session end semantics are semantics representing the end of a session, such as: "good, originally so emergency controlled", etc.; when the two dialogue item clusters are satisfied, the dialogue item corresponding to the publisher in the dialogue item cluster is the semantic of the content related to the missing content type.
The working principle and the beneficial effects of the technical scheme are as follows:
conventionally, the electrolytic hydrogen production site is a scheme for automatically recording the operation problems generated by the hydrogen production electrolytic tank in history and performing emergency control on the hydrogen production electrolytic tank in history, so that the event search scene is limited to the local site, and the system has insufficient applicability. Therefore, the embodiment of the application actively searches in the event searching scene, improves the richness of emergency control events of the hydrogen production electrolytic cell and further improves the applicability of the system. The event search scene does not necessarily have search results meeting all event search conditions, and even if the number of the event search results is small, so that the embodiment of the application introduces event search type conditions, and self-adaptively and flexibly constructs the event search type on the premise of ensuring the search accuracy and rationality, thereby greatly improving the applicability of the system. After a publisher publishes a target event in an event search scene, the target event may be missed, but the missed content may be generated in interactive comments.
In one embodiment, the control method for producing hydrogen by multi-tank parallel electrolysis further comprises:
acquiring and displaying a preset visual model corresponding to the hydrogen production electrolytic tank; the visual model is a three-dimensional model of the hydrogen production electrolytic tank 1:1;

receiving a second emergency control strategy input by a user; the user can give a second emergency control strategy after viewing the visual model for field technicians;
and emergency control is carried out on the hydrogen production electrolytic tank based on the second emergency control strategy.
The working principle and the beneficial effects of the technical scheme are as follows:
according to the embodiment of the application, the operation information and the operation problems of the hydrogen production electrolytic tank are visually pushed to the user, the user can directly analyze and give out a second emergency control strategy, and the emergency control efficiency is improved.
