Problems solved by technology

In the existing technology, the error of river flow velocity measurement will be large once the number of measurements is small, but if the number of measurements is large, the collection and processing of data will be very complicated, so it will affect the determination of the environmental flow of the riparian vegetation belt protection target

Embodiment Construction

[0035] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0036] see figure 1 Shown is a functional block diagram of the flow velocity measurement device used in the environmental flow estimation method of the present invention. The flow velocity measurement device includes a measurement unit 1 , an adjustment unit 3 , an information processing unit 2 and a control unit 4 .

[0037] The measuring unit 1 is used to measure the river water pressure, and transmit the pressure information to the information processing unit 2; the information processing unit 2 receives the pressure information, converts the information into flow velocity information, and outputs it at the same time; The control unit 4 controls the opening and closing of the flow velocity measurement device; the adjustment unit 3 can adjust the height of the flow velocity measurement device, so that i...

Abstract

The present invention provides a flow velocity measuring apparatus used in an environment flow evaluation method, comprising: a pressure disc used for measuring the flow pressure, and outputting measured pressure information; and a data processing instrument connected with the pressure disc, wherein the data processing instrument comprises a pressure processing module used for receiving and processing the pressure information and calculating a flow velocity value. The flow velocity measuring apparatus of the present invention performs unified processing for pressure information obtained from multiple measurements, and converts the pressure information into flow velocity information to obtain more accurate flow velocity, thereby reducing error and enabling the finally obtained flow velocity to be closer to an actual flow velocity.

Description

technical field [0001] The invention relates to the field of water resources allocation, in particular to a flow velocity measuring device used in an environment flow estimation method. Background technique [0002] The riparian vegetation belt belongs to the water and land crisscross zone, and is an important source of aquatic and terrestrial species and a habitat for wild animals. It is an important source of nutrient energy in the river. It directly affects the microclimate of the river, protects the water quality of the river, and maintains the health of the river. Bring huge benefits to people's entertainment, life and production. The riparian zone is also an important control node for nutrient management, soil and water conservation, and freshwater resource protection. Whether its function is effectively performed is related to the health of the watershed ecosystem, and it is an important barrier to maintain the stability of the water area and even the terrestrial ecos...
