Description
A method and system for monitoring and filming power engineering based on artificial intelligence Technical Field
[0001] This invention belongs to the field of power equipment monitoring technology, specifically relating to a power engineering supervision and monitoring method and system based on artificial intelligence. Background Technology
[0002] As the State Grid Corporation of China continues to raise its requirements for the health level of power grid equipment and the reliability of power supply, the number and investment scale of power grid technical renovation and overhaul projects have been increasing year by year. However, the allocation of supporting project management personnel, on-site safety capacity, and qualified construction forces are relatively insufficient, and management shortcomings are becoming increasingly prominent. Although existing power engineering supervision technology has incorporated positioning and video recording methods, it has obvious defects in reliability, intelligence, and systemicity, making it difficult to meet the needs of lean power grid management and control: First, the positioning accuracy of on-site personnel is low, relying heavily on GPS / base station positioning via mobile apps or ordinary check-in devices, with an accuracy of hundreds of meters. This makes it impossible to verify whether the supervisors have arrived at specific substation intervals or equipment operation points, easily leading to problems such as fake check-ins and fictitious positions. Second, supervision records are fragmented and have low credibility. Unstructured data such as images and logs are easily tampered with and lack strong correlation with projects, processes, and equipment, making it difficult to trace and determine responsibility when quality disputes or safety incidents occur. Third, regulatory response is lagging. Supervision data is not integrated with the company-level project management and asset management systems, making it impossible for managers to monitor dispersed sites in real time. They rely more on post-event spot checks, making timely intervention difficult. Summary of the Invention
[0003] To address the aforementioned shortcomings of existing technologies, this invention provides an artificial intelligence-based method, system, terminal, and storage medium for power engineering supervision and monitoring.
[0004] In a first aspect, the present invention provides an artificial intelligence-based power engineering supervision and monitoring method, comprising: S1, performing dual authentication of user identity and logging into an intelligent management and control platform through a supervision and monitoring device, wherein the dual authentication includes password verification and facial liveness detection verification; S2, in response to successful login, obtaining an authorized list of technical renovation and overhaul projects from the power grid resource business platform, establishing an association between the supervision and monitoring device and the target project, and downloading the structured data of the feasibility study report corresponding to the project, the associated power equipment asset code, and the text data of the mandatory power industry regulations of the project's professional category; S3, obtaining initial geographic coordinates and equipment electronic tag information, performing intelligent location calibration through a multi-source fusion algorithm, and generating meter-level to sub-meter-level calibration positioning data; S4, activating the high-definition image recording function of the supervision and monitoring device, collecting real-time video streams from the construction site and caching them to the local storage unit; S5, triggering the edge AI inference module of the supervision and monitoring device to process step S4. The on-site video stream undergoes polarization imaging and multispectral fusion preprocessing to generate a fused video stream. OCR recognition is performed on the nameplates of power equipment in the fused video stream, and time-series analysis is conducted on the construction activities. The recognition results are then checked for consistency with the structured data from the feasibility study report downloaded in S2 and the text data of mandatory power industry regulations. A sequence of process events carrying confidence markers is output. In S6, the process event sequence output in step S5 is received. When the confidence level of key nodes in the process event sequence exceeds a set threshold, a high-resolution image is automatically captured.
