Description

Power operation and maintenance project business state generation method, system and storage medium Technical Field The invention relates to the technical field of project management data processing, in particular to a method, a system and a storage medium for generating a business state of an electric operation and maintenance project. Background In the implementation process of the electric operation and maintenance project, the project management system generally needs to perform state identification on the current execution condition of the project so as to support the business processes of operation and maintenance scheduling, resource approval, performance settlement, risk management and control and the like. In the prior art, the business state of the power operation and maintenance project is updated based on the work order completion condition, the progress node reporting result or the manual confirmation information, and once the state is generated, the state is generally regarded as a deterministic result and is maintained for a long time. However, in an actual engineering scene, the power operation and maintenance project has the characteristics of long period, complex process, repeated adjustment of the execution process and the like. After a certain point of the project meets the triggering condition of the established state, the conditions of reworking work orders, supplementary work, resource addition, acceptance delay and the like still can occur in the follow-up process, and the follow-up business facts often contradict the generated business states. Because the existing project management system lacks a constraint mechanism for continuously and effectively maintaining the condition of the state, the business state cannot be dynamically corrected along with the actual execution condition, and the problem that the project state is inconsistent with the actual execution condition occurs. Furthermore, in the prior art, static judgment or simple rollback is mostly adopted for managing the project service state, so that quantitative expression means for establishing a reliable degree for the state is lacking, and a mechanism for gradually weakening and automatically degrading the state based on subsequent service behaviors is also lacking. Under the condition that multi-source service data are continuously generated, the technical defects are further amplified, project state distortion is easily caused, and accuracy and reliability of operation and maintenance decisions are affected. Therefore, a data processing method capable of dynamically generating, continuously checking and automatically degrading the service state of the power operation and maintenance project based on the evolution process of the service data is needed, so as to improve the reflecting capability of the service state of the project on the actual execution condition. Disclosure of Invention The embodiment of the invention aims to provide a method, a system and a storage medium for generating a service state of an electric power operation and maintenance project, which at least solve the problems that the service state of the existing electric power operation and maintenance project depends on static judgment and cannot continuously check and automatically degrade the status establishment based on subsequent service events. In order to achieve the above purpose, a first aspect of the present invention provides a method for generating a service state of an electric power operation and maintenance project, the method comprising obtaining a project service execution record generated in an implementation process of the electric power operation and maintenance project, and executing event processing on the project service execution record to generate a service event stream with a unified structure, generating a service state instance for representing a current execution stage of the electric power operation and maintenance project according to a preset state triggering rule based on the service event stream, setting a corresponding trusted duration for the service state instance, continuously receiving a subsequent service event in the service event stream after the service state instance is generated, identifying an anti-certification event based on a generation time sequence of the subsequent service event and the service state instance, and executing attenuation update processing on the trusted duration according to the anti-certification event, triggering state degradation processing of the service state instance when the trusted duration meets a preset failure condition, and outputting service state data for reflecting an execution condition of the current electric power operation and maintenance project. The project service execution records comprise any one or more of a work order record used for reflecting the execution condition of a job, a progress node record used for reflecting the advancing condition of a project st
