The output interface 113 is connected to a display device 123 as wind information output means for outputting wind information composed of wind direction and wind speed. The display device 123 may consist of a plurality of LEDs as will be explained later.

Connected to the I/O interface 114 are air volume sensors 124-1 to 124-4 as wind intensity acquisition means for capturing the incoming wind in at least three directions on a plane and obtaining wind intensity information for each of the three directions. It is In this embodiment, there are four air volume sensors 124-1 to 124-4, but there may be three or more. Of course, one housing may be provided with a sensor or the like that captures the incoming wind in at least three directions on a plane and obtains wind intensity information for each of the three directions.

The four air volume sensors 124-1 to 124-4 are arranged at positions equidistant from the center of the disk-shaped base 33 so that the air intake ports are different by 90 degrees. In FIG. 3, for the air volume sensors 124-1 to 124-4, the air intake ports 125-1 to 125-4 are arranged from the center of the circle on the upper surface of the disk-shaped base 33 to the air volume sensors 124-1 to 124-4. opening radially toward the center of the Therefore, the four air volume sensors 124-1 to 124-4 for detecting the air volume on the disk-shaped base 33 have air intake ports 125-1 to 125-4 as shown in the plan view of FIG. They are arranged at positions equidistant from the center of the disk-shaped base 33 so as to differ by 90 degrees. Air volume sensor 124-1 obtains wind intensity information in the direction indicated by arrow X1, air volume sensor 124-2 obtains wind intensity information in the direction indicated by arrow X2, and air volume sensor 124-1 obtains wind intensity information in the direction indicated by arrow X2. 3 obtains wind strength information in the direction indicated by arrow X3, and the air volume sensor 124-4 obtains wind strength information in the direction indicated by arrow X4. As described above, in this embodiment, the air volume sensors 124-1 to 124-4 adopt a configuration in which four wind directions differing by 90 degrees are adopted, and wind strength information in four directions can be obtained.

Although the air volume sensors 124-1 to 124-4 are not particularly limited, MEMS air volume sensors manufactured by Omron Corporation are used in this embodiment. The air volume sensors 124-1 to 124-4 have a somewhat flat rectangular parallelepiped shape. In this sensor, a thin film is formed on a silicon substrate, a heater is provided on the thin film, and thermopiles are provided on both sides of the heater. This is a thermal mass flow sensor of the type that measures the flow rate by capturing the movement of heat that accompanies the movement of air as a change in airflow.

Returning to FIG. 3 again, description will be made. In this embodiment, a main body 30 constituting an anemometer is provided, and a plurality of display devices 123 as wind information output means are provided at equal intervals along the circumference of the circular top plate 32 of the main body 30. It is composed of (here, 16) LEDs 31-1 to 31-16. The circular top plate 32 is a circuit board on which LEDs 31-1 to 31-16 are provided, and 16 LEDs 31-1 to 31-16 are arranged in a radial line dividing a circle into 16 equal parts on the circumference of the circuit board. placed (Fig. 5). As shown in FIG. 6, which is a front view seen from the direction of arrow A in FIG. A plate 35 is provided. When any one of the plurality of LEDs 31 is lit, luminescence appears through the circular acrylic plate 35, and the line segment connecting the center of the circle on the circular acrylic plate 35 and the lit LED 31 is directed from the lit LED 31 to the center. Display output is performed as the direction of the wind. A circular top plate 32 and a circular acrylic plate 35 are fixed in parallel by a column 34 and attached to a disk-shaped base 33 .

In the disk-shaped base 33, the command input device 122, the display device 123, and the air volume sensors 124-1 to 124-4 as wind intensity acquisition means in the wind direction and wind speed measuring device are installed by the configuration of the computer shown in FIG. configuration is provided.

The CPU 101 provided in the disk-shaped base 33 reads a program functioning as a two-direction detection means 181, a vector addition means 182, an output control means 183, and a correction coefficient acquisition means 184 to the main memory 102, and stores this program. The function of each means is realized by execution.

The two-direction detection means 181 compares the magnitudes of the wind strength information in at least three directions (four directions in this embodiment) obtained by the air flow sensors 124-1 to 124-4, and determines whether the wind strength of the highest wind strength is determined. It detects two wind directions from which information and the second highest wind strength information are obtained. The vector adding means 182 generates two vectors whose vector directions are the directions of the two directions detected by the two-direction detecting means 181 and whose magnitude is the wind strength information in each direction. are added to obtain one addition result vector. The output control means 183 outputs the direction of the addition result vector obtained by the vector addition means 182 as wind direction information and the magnitude of the addition result vector as wind speed information to the LED 31 serving as the wind information output means. The correction coefficient acquisition means 184 obtains a correction coefficient based on the result of comparison between the wind direction and wind speed obtained from the addition result vector obtained by multiple test operations and the wind direction and wind speed actually measured during the test operation. be. This correction coefficient is stored in the external storage device 121 and used by the vector adding means 182 . That is, the vector addition means 182 multiplies the second-order wind strength information by the correction coefficient to obtain the second-order corrected wind strength information, and uses this second-order corrected wind strength information to perform vector addition. to get one addition result vector.

The wind direction and wind speed measuring device having the above configuration operates based on a program corresponding to the flowchart shown in FIG. In this embodiment, it is assumed that the operation is started by turning on the power switch configured by the command input device 122 . When the operation starts, wind intensity information is obtained from the wind volume sensors 124-1 to 124-4 (S11). For example, as shown in a square frame in FIG. ), the wind intensity information from the air volume sensor 124-3 is −0.2 (m/s), and the wind intensity information from the air volume sensor 124-4 is 0 (m/s).

After step S11, the CPU 101 arranges the four pieces of wind strength information in descending order and selects the top two pieces of wind strength information (S12). FIG. 9 shows the four pieces of wind strength information shown in FIG. 8 arranged in descending order (from the top of the drawing). , the wind strength information of the air volume sensor 124-2 is 0.32 (m/s).

Next, it is detected whether or not the top two air volume sensors are adjacent (S13). That is, normally when the wind is blowing in a certain direction, the adjacent air volume sensor can obtain a large wind intensity, and in the case of a detection error, the output of the wind direction and air volume is avoided. For this reason, when the number of airflow sensors increases, it is not necessary to be "adjacent", for example, it may be possible to detect "whether it is in a two-adjacent range". If the process branches to NO in step S13, the process returns to step S11 to perform the process.

When branching to YES in step S13, it is detected whether the second wind strength is 0 or less (S14). Similarly to step S13, this also avoids outputting the wind direction and air volume in the case of a detection error that the wind strength is extremely different at the positions of the adjacent air volume sensors. If branched to YES in step S14, the wind direction of the first air volume sensor is used as wind direction information, and the obtained magnitude is output to the wind information output means as wind speed information (S15).

If the process branches to NO in step S14, the CPU 101 multiplies the second order wind strength information by the correction coefficient to obtain the second order corrected wind strength information (S16). The correction factor is a value that approaches the actual measurement value based on the result of comparison between the wind direction and wind speed obtained from the addition result vector obtained by multiple test operations and the wind direction and wind speed actually measured during the test operation. is. In this embodiment, 1.8 is shown as the correction coefficient. 0.58 (m/s) is obtained by multiplying the wind intensity information 0.32 (m/s) of the air volume sensor 124-2 by this correction coefficient of 1.8. FIG. 10 shows the first-ranked wind strength and the second-ranked corrected wind strength.

After step S16, the CPU 101 uses the first wind strength information and the second corrected wind strength information to add these vectors to obtain one addition result vector (S17). Here, the first wind strength information is 0.4 (m/s), the second corrected wind strength information is 0.58 (m/s), and the wind direction of the first air flow sensor is 11, the wind direction of the second airflow sensor is a vector pointing upward in FIG. 11, and the vector addition yields one addition result vector F as shown in FIG. .

After step S17, the CPU 101 uses the direction of one obtained addition result vector F as wind direction information, and outputs the magnitude of this addition result vector F as wind speed information to the wind information output means (S18). In this embodiment, a display device 123 composed of 16 LEDs 31-1 to 31-16 is used as output means. Therefore, as shown in FIG. 12, the direction from the lighted LED 31-3 to the center O on the line segment connecting the center O of the circle of the circular top plate and the lighted LED (here, LED 31-3) is the wind direction. illuminates one of the plurality of LEDs. As for the wind speed, at least one of the brightness and hue of the LED can be changed according to the strength of the wind speed based on the magnitude of the addition result vector. That is, the higher the wind speed, the higher the brightness, and as for the hue, as shown in FIG. may be displayed as the weakest.

In the first housing 10, the CPU 101 as the output control means 183 uses the direction of the obtained one addition result vector F as the wind direction information in step S18 of the flow chart shown in FIG. The communication interface 115 and the transmitting/receiving unit 135 function as wireless transmission means for transmitting the wind direction information and the wind speed information output from the output control means 183 by wireless communication when the wind direction information and the wind speed information are output to the wind information output means as wind speed information. do.

In the second housing 20, the wind direction information and the wind speed information transmitted from the wireless transmission means composed of the communication interface 115 and the transmission/reception part 135 are received by the transmission/reception part 301, which is wireless reception means, and this reception is performed. The controller 300, which is the second housing-side output control means, outputs the obtained wind direction information and wind speed information to the display device 303, which is the second housing-side wind information output means. As a result, the display device 303, which is the second housing-side wind information output means, outputs wind information composed of the direction and speed of the wind.
