Abstract: Patrol inspection is an important means to ensure the safety of hydropower stations. Based on summary of the advantages and disadvantages of traditional patrol inspection schemes, combined with digital inspection methods, this paper proposes an optimized scheme and a new online inspection system scheme is formed. Upgrading of inspection functions, the optimization of inspection types and content as well as the optimization of inspection systems are realized. After the scheme optimization, the degree of data structuring has been improved, the data redundancy has been significantly reduced, and the defect management function has been added. Moreover, the online inspection system designed based on this scheme has been applied to Ertan hydropower station.

Key words: patrol inspection, online inspection, data structuring, data redundancy, defect management

摘要： 巡视检查是保障水电站安全的重要手段。在总结传统巡检方案利弊的基础上，结合数字化巡检手段，优化巡检方式，形成了新型在线巡检系统方案。该方案实现了巡检功能升级、巡检类型及内容优化、巡检系统优化。方案经优化后，进一步提高了巡检结果的结构化程度，数据冗余显著减少，并新增了缺陷管理功能，实现了巡检工作全过程数字化管控。基于本方案设计的在线巡检系统已应用于二滩水电站。
