Abstract:In Binzhou Municipality, the online hydrology flow measurement system involves multiple suppliers and various types of equipment, with problems such as over online flow measurement platforms, low data security, and cumbersome operations. After the construction of Hydrological Online Flow Measurement and Monitoring Platform in Binzhou, it has realized unified system control, data transmission, analysis and summarization, and centralized management, greatly improving the operability and practicability of online flow measurement facilities. This paper clarifies the research and development construction process of the platform, introduces its main characteristics and function optimization methods, analyzes and discusses the data integration of the platform system, and provides experience and practices, so as to offer references for the construction of online flow measurement and monitoring platforms in the future.
