Measure main frame 2 to comprise further:
Wind velocity signal treatment circuit 21, the wind velocity signal transmitted for receiving sounding rod 1 obtains air speed value.This wind velocity signal treatment circuit 21 can add the process chip such as single-chip microcomputer for amplifying circuit, after namely first being amplified by wind velocity signal, is sent to single-chip microcomputer; The relation that the wind velocity signal of the output of the sounding rod 1 after amplifying is corresponding with actual wind speed value is stored in advance in single-chip microcomputer.Those skilled in the art are to be understood that, this wind velocity signal treatment circuit 21 also can be other change-over circuits, as long as the wind velocity signal that sounding rod 1 exports can be realized to be converted to actual wind speed value corresponding with it, as wind velocity signal treatment circuit 21 adopts AD converter and other change-over circuits of the prior art to realize, also can hardware circuit be only adopted to realize.
Display panel 22, is connected with wind velocity signal treatment circuit 21, for receiving air speed value that wind velocity signal treatment circuit 21 obtains and showing.Arrange two Displaying Meters in display panel 22, Displaying Meter has different ranges, selects corresponding Displaying Meter to show according to the size of air speed value.
As a kind of specific implementation, this display panel 22 can be touch color screen (that is: touch controlled color screen), and touch color screen is more humane, easy to use.As shown in figures 2 a and 2b, can arrange two wind speed range abilities on this touch color screen, namely range is 0-5m/s, and range is 0-30m/s.When the air speed value measured is less than 5m/s, measurement range selection is 0-5m/s; When the air speed value measured is greater than 5m/s, automatic range switching is 0-30m/s.As another kind of specific implementation, this display panel 22 can comprise two mechanical Displaying Meters, and two Displaying Meters have different ranges, selects corresponding Displaying Meter to carry out showing according to the size of air speed value.Those skilled in the art should be appreciated that the Displaying Meter arranging more than three or three is also fine, and specifically carry out according to demand arranging.
Power supply 23, powers for giving measurement main frame 2.
The wind gage that the present embodiment provides, wind velocity signal treatment circuit 21 receives sounding rod 1 and measures the wind velocity signal obtained, and obtains air speed value according to this wind velocity signal; Display panel 22 is connected with wind velocity signal treatment circuit 21, the Displaying Meter of two different ranges is at least set in display panel 22, corresponding Displaying Meter is selected to show according to the size of air speed value, this wind gage just making the present embodiment provide can according to the size of current air speed value, the range corresponding with it is selected to show, be applicable to different measurement environment, versatility is good, is convenient to promote the use of.Meanwhile, the wind velocity signal treatment circuit 21 in the wind gage that the present embodiment provides and display panel 22 are integrated in be measured in main frame 2, when this just uses user to measure out of doors, without the need to carrying host computer (notebook), is user-friendly to.
On the basis of such scheme, sounding rod 1 can comprise handle and be arranged on the measuring staff that handle inner can stretch, and the top of measuring staff is provided with hot-bulb formula wind speed acquisition probe 11, and the top of hot-bulb formula wind speed acquisition probe 11 is provided with probe cap.Because the length of measuring staff can stretch, this is just convenient for users to use, and the tensile elongation of measuring staff can design according to demand, the longest 1200mm that can stretch of general selection, and the shortest is 270mm, and the diameter of probe is 11mm; When wind gage works, pull up the probe cap on hot-bulb formula wind speed acquisition probe 11 top, when wind gage does not work, put probe cap, be conducive to protection hot-bulb formula wind speed acquisition probe 11 not damaged, extend the serviceable life of wind gage.
On the basis of such scheme, power supply 23 can for being nominally the chargeable lithium cell of 3.7V; Power supply 23 can also comprise the charging circuit be connected with this chargeable lithium cell; As shown in Figure 3, this charging circuit can comprise chip TP4056 and its peripheral circuit.This just makes this wind gage be applicable to the outdoor environment without electrical network, meanwhile, adopts chargeable lithium cell to substitute traditional dry cell, is convenient to recycle, facilitates user, saved the cost of user.In use, when the circuit of battery is not enough, can showing at display unit, charge in time with reminding user.
On the basis of such scheme, when display panel 22 adopts touch color screen, the brightness of this touch color screen can regulate, and this just makes this wind gage be applicable to different photoenvironments, also can show clearly under high light.Touch-key can also be comprised, for arranging parameter during measuring wind speed in this touch color screen.By arranging button, the pattern of the measuring wind speed preset in wind velocity signal treatment circuit 21 can be selected easily, as exported current wind speed in real time to display panel 22, or export wind speed mean value at set intervals to display panel 22, or the maximal value of output wind speed and/or minimum value are to display panel 22, or fast/slow measurement is carried out to wind speed, or keep air speed data on present display panel 22 etc., simultaneously by arranging button, the demarcation numerical value preset in wind velocity signal treatment circuit 21 can be revised easily, as the threshold value etc. that wind speed is reported to the police, easy to use.
On the basis of such scheme, measuring main frame 2 can also comprise warning piece, and this warning piece is connected with wind velocity signal treatment circuit 21, for exceeding predetermined threshold value alarm at wind speed.As a kind of specific implementation, warning piece can be the flashing lamp be arranged on touch color screen and/or the hummer be arranged on measurement main frame 2.Different flashing lamps can be set when wind speed exceedes higher limit or lower limit and/or hummer is reported to the police, be convenient to user and distinguish.
On the basis of such scheme, measure in main frame 2 and can also comprise DC/DC change-over circuit, for by the voltage transitions of chargeable lithium cell 3.7V be 5V for chips such as single-chip microcomputers, or be that the voltage of 3.3V uses to the heater strip heating in hot-bulb formula wind speed acquisition probe 11 by the voltage transitions of 5V.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still among the protection domain that the utility model creates.
