Fig. 1 is the realization procedure chart of invention；
Fig. 2 (a) is without the velocity profile in adaptive situation, and Fig. 2 (b) is the fluid velocity profile drawn out using this method
Figure；
Fig. 3 (a) is continuous compression type velocity profile, and Fig. 3 (b) is sliding window type velocity profile.
Specific embodiment
Combined with specific embodiments below, the present invention is furture elucidated, it should be understood that these embodiments are merely to illustrate the present invention
Rather than limit the scope of the invention, after the present invention has been read, those skilled in the art are to various equivalences of the invention
The modification of form falls within the application range as defined in the appended claims.
As shown in Figure 1, user configures the display number of plies using the instrument configuration module at aobvious control interface in engineering
LayerCount, flow velocity show maximum value Vmax and are switched to sliding window type velocity profile by continuous compression type velocity profile
The parameters such as time point ChangeTime, when flow measurement, system parses the data such as the depth obtained from serial ports, flow velocity.
LayerCount and Vmax is adaptively adjusted according to actual measurement flow velocity and depth, can be obtained currently most using bathymetric data
The flood number of plies makes LayerCount be equal to maximum water layer number, similarly, Vmax is made to be equal to the maximum flow rate value currently measured, according to
LayerCount and Vmax redraw velocity profile.I.e. when surveying floors and flow measurement value is greater than default range, software can be according to reality
The hierarchy number and flow rates of measured value adjust automatically display interface.Slave continuous compression finally adaptive according to ChangeTime value
Selection is suitble to the display methods of current flow measurement situation in type and sliding window type velocity profile, when the sample point sum point in system
Reach ChangeTime, plotting mode will be switched to sliding window type velocity profile.
Fig. 2 is used to compare self adaptation stream Sound Velocity Profile and non-adaptive formula velocity profile.It is 30 that LayerCount, which is arranged,
Layer, Vmax 1.0m/s start flow measurement.Fig. 2 (a) is without the display under the conditions of adaptive as a result, wherein abscissa is sample point,
Ordinate is to survey bottom as a result, color value represents flow velocity size, and the flow velocity for showing that the number of plies is excessive at this time, and being arranged shows that maximum value is inclined
Small, the flow velocity resolution ratio for the water layer observed needed for causing is smaller, it is difficult to observe.Fig. 2 (b) is the self-adaptation type stream using this method
Sound Velocity Profile, when software receives depth data Depth and flow speed data V by serial ports1、V2、。。。。。。VLayerCount, enable
LayerCount=max (LayerCount, Depth/layerThickness+1), layerThickness indicate water body layering
Thickness, Depth/layerThickness+1 expression be that layer is calculated according to the lift height of water depth and artificial settings
Number, Vmax=max (Vmax, max (V1、V2、。。。。。。VLayerCount)), LayerCount=17 layers at this time, Vmax=1.7m/
S updates velocity profile, that is, completes adaptive process.Compared to display of the nothing under the conditions of adaptive as a result, change in flow feelings
Condition is more clear, and is not needed user and frequently interacted.
Fig. 3 is used to compare continuous compression type velocity profile and sliding window type velocity profile.LayerCount=is set
30 layers, Vmax=1.0m/s, ChangeTime=800 is set, and setting window long=100, adaptive process is opened in selection.Fig. 3 (a)
It is the case where continuous compression type velocity profile is when sample point reaches 800, passes through adaptive LayerCount=17 at this time
Layer, Vmax=1.7m/s, by image it can be found that being difficult to observe local change in flow situation when sample point is more.Fig. 3
It (b) is sliding window type velocity profile, when sample point is more than 800, plotting mode is changed to sliding window type, i.e., totally 100 in window
Sample point carries out sliding and shows, the change in flow situation for the sample point that number is 701~801 is shown in velocity profile.
LayerCount=15 layers at this time, Vmax=1.2m/s, the more visible observation local velocity situation of change of energy.This method is by two kinds
Flow velocity expression combines, and adaptive selects the fluid velocity profile method for drafting for being suitble to current flow measurement situation, and user can also
Adaptive, two kinds of display methods of free switching are closed with selection.
The adaptive display method of acoustic Doppler fluid velocity profile instrument display and control software can be adaptive selection be suitble to it is current
The display methods of flow measurement situation adjusts relevant diagram parameter, so that velocity profile is kept higher resolution ratio, reduces simultaneously
The interaction complexity of user.
