新能源运维视频存证与安全管控系统
By introducing video upload and work order association, inter-frame hash chain generation, atomic access control for review, and multi-level review process into the new energy operation and maintenance video evidence storage system, the problems of video frame-level tampering and insufficient access control have been solved. This has enabled the reliable anchoring of video content and the full traceability of the review process, thereby improving the system's security and adaptability.

AI Technical Summary
Existing technologies for video evidence storage and review in new energy operation and maintenance suffer from insufficient capabilities to identify video frame-level tampering, inadequate granularity of review authority control, and weak binding between review data and video content. These issues result in low credibility of video evidence storage and poor compliance traceability of the review process.
The system employs a video upload and work order association module, an inter-frame dependency hash chain generation module, an audit atomic permission control module, and a multi-level audit process execution module to establish a unique mapping relationship between wind power operation and maintenance work orders and operation videos. It achieves reliable anchoring of video content through an inter-frame strong dependency hash structure, splits the audit process into indivisible atomic operations, configures a hierarchical permission whitelist, and synchronously updates audit operation data to the chain hash structure.
It improves the ability to prevent video content from being tampered with and the accuracy of data integrity verification, realizes refined control of the review operation and full-process traceability, enhances the stability of system operation and data security, and adapts to the video evidence storage and security management needs in the field of new energy operation and maintenance.
