Embodiment
Referring now to Fig. 1,, traditional electronics wind gage comprise one be used for electronic component, as the shell of calculation element etc. and power supply thereof.
Measuring unit comprises a ceramic cylinder 2, and heater coil 4 wherein is provided, and with this heater coil 4 outside surface of ceramic cylinder is heated to a temperature that is higher than environment temperature far away, if wind gage is used for gentle weather, this temperature for example is 100 ℃.
If wind gage is used for extreme climate, as polar region or desert area, the external temperature of ceramic cylinder can be different.
At the outside surface of ceramic cylinder, and the outside of heater coil, temperature sensor 5 and 6 is placed around cylinder, thereby measures the surface temperature of cylinder in the corresponding angular zone of representing with the position, angle of each temperature sensor.
Fig. 2 illustrates a similar wind gage with stereographic map, wherein can see the angle orientation around the temperature sensor 6 of cylinder.
Sensor 5 is the whole bands around cylinder, has been used to the measurements and calculations wind speed before this, and single sensor 6 is used for extracting wind direction information from only three the measurement numerical value of typical eight sensors.
In this configuration, wind gage is exposed in the wind, and angle orientation sensor the most against the wind is that cooling is maximum, and other sensors are less according to positions cooling degree separately.
Three sensors comprise cooling proximity sense maximum and its left and right sides, are used to calculate wind direction, and the signal of all the sensors is used for calculation of wind speed jointly.
Such wind gage is used for a lot of application scenarios at present, and understanding wind speed and wind direction are very important in these occasions.
In most of application scenarios; the ceramic cylinder of the very fast discovery wind gage of people need avoid being subjected to the protection of influences such as rainwater, dust, physical shock; therefore be necessary to be provided with a lid on the top of cylinder; but consideration for mechanical stability; this lid can not be fixed on the top of cylinder simply; and need support with the support bar that extends up to lid from substrate, shown in Fig. 3 a.Can see shell 3 among this figure, settle the ceramic cylinder 2 that has temperature sensor 6 above the shell.
Place an over cap 9 that supports by support bar 10 on the ceramic cylinder 2, in Fig. 3 b, can see the xsect with hydrodynamic profiles of support bar 10 better.Bar 10 is tried one's best outer placement away from the ceramic cylinder 2 that is positioned at circular-base 8 centers, and the top and bottom of bar are separately fixed at the outer ledge 12 of substrate and lid.
At first, these support components are round bar, but find afterwards, and round bar disturbs the laminar flow of wind and produces great turbulent flow.
In order to address this problem, bar is made with the shape of fluid dynamics profile, and it reduces the turbulence effect that still can produce.
Fig. 4 a and 4b illustrate two the wind scorpion simulations of geometric configuration in an air channel of being discussed, and Fig. 4 a illustrates the situation according to the wind gage of Fig. 1 or 2 thus, and Fig. 4 b illustrates the situation according to the wind gage that comprises the hydrodynamic force support bar of Fig. 3.
Can see the circumference 40 of representing ceramic cylinder among Fig. 4 a, and the support bar 41 with certain profile.
Among Fig. 4 a, wind blows from direction 42, promptly lucky alignment rods 41 and cylinder 40, and can see the turbulent flow that in the wind profile diagram, is right after in bar 41 back generations.
Among Fig. 4 b, wind direction is from direction 43, can see the turbulent flow behind the bar 43 of equidirectional, makes that cylinder 40 is undisturbed.
At present, the phenomenon that the present inventor faces is if impacted on the surface of cylinder by the wind of disturbance, the cooling effect of wind is stronger, if having laminar flow pattern, wind just has this situation, mean under the situation of Fig. 4 a, the cooling effect that is subjected to towards the cylinder zone of wind is stronger than the cooling effect that is subjected to towards the cylinder zone of wind among Fig. 4 b, and both wind speed are identical.
Fig. 5 a is a chart, illustrates around the wind edge to turn to, and during promptly from-180 ° to+360 °, the signal of a particular sensor in the different sensors that is added to.
Can see, for each sensor, in case wind around sensor just over against the zero-bit of the particular sensor of wind from-22.5 ° forward to+22.5 °, the measurement value of electrical signals of specific temperature sensor gets back to 3.2 then from about 3.2 to 3.8 (in zero-bits).
Every other sensor all experiences same variation in same wind direction change.
The measurement that Fig. 5 b representative is identical with Fig. 5 a, but wind gage does not have the support bar around ceramic cylinder.
Clearly, the curve of each sensor is along with the change of wind direction changes all very level and smooth.
See Fig. 6 now, a housing 3 that comprises all wind gage electronic components is arranged, and this housing is closed the substrate of the similar ceramic cylinder of ceramic cylinder of plate formation and Fig. 3 by a plate 8 on top.
Center on ceramic cylinder 2 and be provided with a structure 15 apart from latter farthest basically, as the mechanical support of lid 9 in substrate 8.
Supporting construction 15 comprises the direction inclination or the relative substrate 8 of relative ceramic cylinder 2 and covers 9 bar-like support elements 10 that tilt.
According to embodiment shown in Figure 6, supporting construction 15 comprises a hollow cylinder, wherein is cut with the cannelure that is parallel to each other, and bar 10 has constituted the remainder of the cylinder between per two parallel slots.
Supporting construction or support cylinder 15 for example are fixed by welding in the substrate and cover.
Groove on the support cylinder 15 makes wind energy enough enter into its inside, and the same mode of employing and prior art is cooled off ceramic cylinder 2, just cooling effect be independent of to a great extent wind from the angular direction, because the hydrodynamic force flow pattern from support bar 10 to ceramic cylinder on 2 paths all is identical on all directions, what change with direction only is that cooling air impacts the height on the cylinder 2, but this can not change the measured value of temperature sensor.
Referring now to Fig. 7,, will explain that in the arrangement according to the invention, wind direction will minimize the effect of the cooling of sensor, and even can eliminate fully.
Typically, in the prior art, a sensor has the open architecture protection that top 9 ' and bottom 8 ' are supported by one, has discussed as reference Fig. 3 a and 3b.
In fact the problem that such wind gage runs into originates from the sensing surface of sensor or the tractive current inside fully behind a support bar, perhaps fully in its outside, and perhaps part portion within it.
Singularity of the present invention is to find a kind of method, obtains a kind of geometry, and a kind of average flow pattern that is independent of wind direction behind support bar can be provided.
Therefore, obtain a kind of " on average " flow disturbance that is independent of wind direction at sensor surface.In a model machine, support bar twines sensor, and the sensor surface that impacted of this " on average " air-flow can not change along with any variation of direction like this, and only responds wind direction on its total direction, still keeps identical pattern.
Fig. 7 a illustrates the angular orientation that two kinds of different wind can " be seen " sensor 2 with 7b.。Among Fig. 7 a, a support bar 10 ' is crossed the center of sensor, among Fig. 7 b, two support bars 10 " cross the least significant end of sensor.
In fact these two extreme cases have obtained the cooling effect same to sensor, because can think that in both cases the supported bar of sensor surface of same quantity covers, therefore same disturbance flow and total ratio of non-disturbance flow act on the sensor.In the prior art, can be easy to imagine, can produce sensor as direction same among Fig. 7 a and the 7b and all be capped, or the situation that does not have support bar to cover fully.
For example adopt corrugated plate or mesh can obtain and utilize the resulting similar effect of tilting bar, and the oriented phase of each element tilt for the line shaft of sensor.
The present invention is illustrated by an embodiment; but be to be understood that; protection scope of the present invention exceeds this embodiment, and comprises that the hydrodynamic force flow pattern of the wind between the wind sensor that can make support bar and ceramic cylinder or any other type is independent of the inclination supporting construction of any kind of wind direction.
