Description
Technical field
This application involves ultrasonic wind velocity indicator alignment technique fields, more particularly to one kind is for carrying out ultrasonic wind velocity indicator
The calibration equipment in school zero.
Background technique
The description of this part only provides and discloses relevant background information to the application, without constituting the prior art.
When the working principle of ultrasonic wind velocity indicator is that ultrasonic wave is propagated in air, due to the influence of wind speed, sound is in sky
The wind speed propagated in gas can generate variation.In a certain range, transmitting transducer emit signal, respectively with the wind with the feelings of contrary wind
Under condition, two signal time delay (time difference relative to transmitting signal) differences received by energy converter are received, when using this
Between difference carry out wind speed and direction measurement.
In signal processing, influenced by filter delay, transducer parameters difference etc., so that ultrasonic wind speed
Ambient wind velocity around instrument is 0, but the wind speed of ultrasonic wind velocity indicator actual measurement is not 0, this makes ultrasonic wind velocity indicator
Zero point value generate drift (that is, the numerical value of zero point changes).Null offset will seriously affect the measurement of ultrasonic wind velocity indicator
Precision, especially to small measuring wind speed when, the influence of null offset is particularly acute, in addition will thoroughly cause ultrasonic wind velocity indicator without
Method works normally, so needing to carry out zero correction to ultrasonic wind velocity indicator.
However, the existing method that school zero is carried out to ultrasonic wind velocity indicator be mostly ultrasonic wind velocity indicator factory before,
It is tested by manufacturing no-wind environment in wind-tunnel, records the reception signal and obtained wind of this moment ultrasonic wind velocity indicator
The case where fast wind direction, to realize school zero.However, by the variation of the use conditions such as temperature, humidity, or by misty rain, dust etc.
The influence of weather conditions, and influenced by factors such as energy converter fouling or abrasions, the zero point value of ultrasonic wind velocity indicator is often
Drift is generated, requires to re-scale its zero point in this case.Re-calibration is generally required ultrasonic wind speed
Instrument is disassembled from workplace, and ultrasonic wind velocity indicator is placed in wind-tunnel, and in the case where windless, is re-measured
The zero point value of ultrasonic wind velocity indicator, and then realize the zero correction of ultrasonic wind velocity indicator.
Therefore, the zero point correction method of the prior art needs to dismantle ultrasonic wind velocity indicator, could complete calibration, correction effect
Rate is lower and higher cost.
It should be noted that the above description of the technical background be intended merely to it is convenient to the technical solution of the application carry out it is clear,
Complete explanation, and facilitate the understanding of those skilled in the art and illustrate.Cannot merely because these schemes the application's
Background technology part is expounded and thinks that above-mentioned technical proposal is known to those skilled in the art.
