Method, system and control device for real-time measurement of runoff velocity

Abstract

The invention discloses a method, system and control device for real-time measurement of runoff flow velocity, wherein the real-time measurement method of runoff flow velocity includes: receiving instantaneous flow velocity values ​​and liquid level values ​​of multiple detection points in at least one detection point group measured at the same time, Wherein, multiple detection points in each detection point group are distributed at intervals along the runoff width direction; according to the instantaneous flow velocity value and liquid level value of multiple detection points in the at least one detection point group, respectively calculate the described The average flow velocity at multiple detection points in at least one detection point group; calculate the flow velocity of the runoff according to the average flow velocity at multiple detection points in the at least one detection point group, and realize the real-time online measurement of the runoff flow velocity The measurement reduces the number of personnel and equipment involved in the measurement process, greatly reduces the measurement work, and saves measurement costs.

Description

technical field [0001] The invention relates to the technical field of river flow velocity measurement, in particular to a method, system and control device for real-time measurement of runoff flow velocity. Background technique [0002] At present, the common method of measuring the flow velocity of the river is the use of ADCP (Acoustic Doppler Current Profilers, Acoustic Doppler Current Profilers) measurement, which can be divided into navigation type or fixed type, that is, the use of ADCP flow velocity measurement principle The vertical line in the watershed section is different The flow velocity at the point level and the average flow velocity on different vertical lines are used to calculate the overall river flow according to the flow velocity at multiple points in the section. This kind of equipment is expensive. When using it for surveying, it needs to be calibrated and debugged to input a variety of measurement parameters, which is labor-intensive. physical resour...
