Because the reed device (12) is fixed on one side and the free vibration end on the other side, such as the fixing method of the reed of a harmonica, two completely different scales are generated by blowing and sucking the same reed.

Furthermore, the reed device (12) comprises a first reed (121) and a second reed (122), one ends of the first reed (121) and the second reed (122) close to the first airflow passage port (111) are set as fixed ends (123), one side ends of the first reed (121) and the second reed (122) are fixed, one side ends of the first reed and the second reed are close to the second airflow passage port (112) and are set as free ends (124), the first reed (121) and the second reed (122) form a certain included angle and are symmetrically arranged on an inner central axis (X) of the airflow passage (11), and when wind direction airflow is injected from the first airflow passage port (111) and flows out from the second airflow passage port (112), two completely different high and low sound steps are formed when the wind direction airflow is injected from the second airflow passage port (112) and flows out from the first airflow passage port (111).

The direction signal device (15) is one of a gyroscope, a compass and the like.

The invention also discloses a reed type wind power and wind direction detection device, which comprises a mounting bracket (2) and is characterized by comprising the detection sensors (1) arranged on the mounting bracket (2) and a signal collection processor (21) arranged on the mounting bracket (2).

Detailed Description

The invention is further described with reference to the following drawings and detailed description.

As shown in fig. 1 and 2, a reed type wind force and direction detecting sensor 1 is used for real-time monitoring and detecting wind force and direction in field or sea navigation operation, and includes an airflow channel 11, a reed device 12, and an audio detecting sensor device 13 fixed on the reed device 12, wherein the reed device 12 is arranged on an internal central axis X of the airflow channel 11, and includes a plurality of reeds fixed near one end of one airflow channel opening of the airflow channel 11, and wind enters the airflow channel 11 from two different airflow channel openings of the same airflow channel 11 to form completely different scales. Because the reed assembly 12 is fixed on one side and free vibrating on the other side, as is the case with the reed attachment method of a harmonica, blowing and sucking the same reed results in two completely different scales.

As shown in fig. 2, reed device 12 includes first reed 121 and second reed 122, one end of first reed 121 and second reed 122 near first airflow passage opening 111 is set as fixed end 123, one side end of first reed 121 and second reed 122 is fixed, and one side end of second reed 122 is set as free end 124 near second airflow passage opening 112, first reed 121 and second reed (122) form a certain included angle and are symmetrically arranged on inner central axis X of airflow passage 11, when wind direction airflow is injected from first airflow passage opening 111 and flows out from second airflow passage opening 112, and when wind direction airflow is injected from second airflow passage opening 112 and flows out from first airflow passage opening 111, two completely different high and low sound steps are formed.

As shown in fig. 2, the audio detection sensor device 13 is disposed on the side of the fixed ends (123) of the first spring piece 121 and the second spring piece 122. That is, as in the harmonica principle, the blowing from the fixed end 123 toward the inlet of the airflow reed and the blowing from the free end 124 toward the inlet form different high and low scales.

As shown in fig. 1, the first air flow passage opening 111 and the second air flow passage opening 112 of the air flow passage 11 are provided as two bell mouths of large-diameter openings at both sides of the middle small-diameter opening symmetrically with respect to the center reference plane Y of the air flow passage 11, the inner diameter slopes of the bell mouths guide different wind directions, and the reed devices form different vibration audio signals. The horn mouth not only can ensure the size of the air flow, but also has certain guidance in the direction due to the guiding effect of the change of the inner diameter.

As shown in fig. 3-5, gas flow channel 11 comprises a plurality of symmetrical sets of first gas flow channel port 111 and second gas flow channel port 112 arranged in a plurality of gas flow channels around a concentric array, with a common channel cavity 14 at the center of the circle and a corresponding reed device 12 at each gas flow channel centerline X.

Reed unit 12 includes a fixed end of first reed 121 and a fixed end of second reed 122 disposed at the intersection of center line X of each gas flow passage 11 in passage cavity 14 on the side near the end of first gas flow passage port 111, and a free end near the end of second gas flow passage port 112. Completely different scale resonance signals are formed in the two directions forming the respective air flow channels 11. For example, six trumpet-shaped airflow passage openings form three groups of airflow passages 11, and four trumpet-shaped airflow passage openings form two groups of airflow passages 11. And reed devices 12 with different scales are arranged in different groups of airflow channels, the length, the size and the material of the reeds can be designed, and the reed devices with different scales are well known and are not described in detail.

The direction signal device 15 is one of a gyroscope, a compass, etc.

As shown in fig. 6 to 10, the present invention further discloses a reed-type wind power and wind direction detecting device, which comprises a mounting bracket 2, a plurality of detecting sensors 1 mounted on the mounting bracket 2, and a signal collecting processor 21 disposed on the mounting bracket 2. The signal collection processor 21 collects the sound vibration signal of the reed of each detection sensor airflow channel detected by the audio detection sensor device 13 provided in each detection sensor, and in general, the audio detection sensor device 13 is a capacitive sound detection sensor, and converts the sound vibration signal of the reed into an electric signal to transmit to the signal collection processor 21.

The upper bracket 22 and the lower bracket 23 of the normal condition mounting bracket 2 are both circular structures, and are in telescopic rotary connection, a certain damping force is formed by an elastic device, a direction signal device 15 in the detection sensor, namely a direction signal detected by a compass or a gyroscope, and the like, and the relative positions of the upper bracket 22 and the lower bracket 23 are adjusted in a rotating manner, so that the corresponding direction of the detection sensor is adjusted, for example, the detection in the north-south or north-north direction, not only is the indication function of the directional signal realized, but also the directional signal of the sensor is used as the reference data of the wind direction, and the three functions of adjusting the direction of the sensor are realized. The direction signal device 15 may also be mounted on the upper bracket. For example, three detection sensors 1 are arranged in a Y shape, or six detection sensors 1 are arranged on the circular upper bracket 22 in a concentric array, so that the extraction of the multi-directional windward signal data is realized. And more than three detection sensors 1 can also be made by arranging different scale reed devices.

The invention also relates to a reed type wind power and wind direction detection method, which is a detection method for calculating and analyzing the wind direction and the wind power by collecting the audio signal data of reed vibration signals on a sensor by using the detection sensor or the detection device, and comprises the following specific steps:

a. and (3) detection signal extraction: extracting reed vibration audio signals in a plurality of air flow channels which are arrayed concentrically, and transmitting the signals to a signal analysis processing device;

c. and (3) comprehensive signal processing output: and integrating a plurality of signals, combining direction information data of the detection device, and processing and outputting real-time wind direction and wind power numerical values.

In principle, the reeds in the airflow channels arranged in the concentric array are set to be devices with different scales, and after the single ends of the reeds are fixed, like the harmonica principle, the scales formed in different airflow directions are different, and the scales of whistle of each group of reeds are different, so that the sound signals of each group of reeds can be clearly distinguished on the frequency spectrum in the received signals. In order to avoid aliasing of the sound signals emitted by the sets of reeds, the difference in the musical scales needs to be large enough. The invention differentiates the sound spectrum signals of the reeds from two aspects, and is very advantageous in processing method. .

The above is one embodiment of the present invention. Furthermore, it is to be understood that all equivalent or simple changes in the structure, features and principles described in the present patent concepts are included in the scope of the present patent.
