Abstract: By analyzing the problems existed in current dam safety monitoring system, this paper puts forward the necessity of building an online dam safety monitoring system based on software as a service. Based on demand analysis, the system function design and R&D were carried out. The system was popularized and applied to many hydropower stations, which created a new service mode based on safety big data, and improved the level of safety management of reservoir dams.

Key words: online monitoring system, software as a service, big data

摘要： 通过分析当前大坝安全监测系统存在的问题，指出了基于SaaS（软件即服务）的大坝安全在线监控系统建设的必要性。在需求分析基础上进行了系统功能设计及研发，系统在多座水电站进行了推广应用，开创了基于工程安全大数据的服务新模式，提升了水库大坝安全管理水平。
