Abstract

The invention discloses an open channel water delivery monitoring method based on multi-information fusion, which includes a camera, a water level gauge, a drone, a drifting buoy and a main control machine; Measuring unit; first obtain the water level information at the entrance and exit, and obtain stable open channel flow data through historical data and real-time data. Based on the above data, a specific one-dimensional open channel model can be established to know the fluid velocity change at any point and at any time. The change information of the water level is finally formed by the random parallel optimization method and the measured real-time data to form an objective function, and corrected and fused, so as to obtain a more accurate actual operation status of the open channel; the present invention provides a complete monitoring system and accurate multi-information collection An open channel water delivery monitoring method based on multi-information fusion.

Description

technical field [0001] The invention relates to the field of multi-information fusion and data assimilation of an open channel water delivery system, more specifically, it relates to an open channel water delivery monitoring system based on multi-information fusion. Background technique [0002] The traditional method of automatic flow measurement of hydraulic structures is to collect information through fixed installation of water level, gate level sensors and communication transmission devices, and process the information through microcomputers, so as to obtain the water level, flow, water volume, etc. of hydraulic structures. parameters to realize the automatic water measurement process. [0003] The modern hydraulic building method for measuring water flow has the characteristics of economy and simplicity. The key to measuring flow with this method is the determination of various coefficients in the hydraulic formula, such as flow coefficient, flow velocity coefficient, ...
