Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for measuring wind velocity using an ultrasonic wave,

The present invention relates to a method and apparatus for continuously transmitting a square wave of a predetermined frequency to a plurality of high-speed ultrasonic sensors and measuring a current wind velocity and a wind direction based on a phase difference between a signal received through the ultrasonic sensor and a transmission signal, And a measuring method thereof.

The wind direction anemometer is a device capable of simultaneously measuring the wind direction and the wind speed. Recently, a wind speed measuring device for measuring wind speed and direction using an ultrasonic sensor has been developed and used. The wind speed measuring device using ultrasonic waves has difficulty in miniaturization but has high accuracy and non-contact type, and thus has excellent durability.

In addition, the device for measuring the wind direction velocity using the ultrasonic wave is configured to use a method of using the change of the movement time of the ultrasonic wave in general and a method of using the frequency change due to the vortex generated by the flow of the fluid by inserting the obstacle in the wind path do. However, since the method using the frequency variation according to the vortex generates an irregular vortex due to a pulsating unsteady fluid, the accuracy is lowered and it is not suitable for the measurement of wind direction in structure. Therefore, in order to simultaneously measure the wind speed and direction, Use the travel time.

That is, the above-described wind speed measuring apparatus using the change in the travel time of the ultrasonic wave is characterized in that the ultrasonic transceiver is placed facing the same line having a certain angle with the moving direction of the fluid, and the ultrasonic wave traveling time change due to the fluid moving between the ultrasonic transceivers So as to measure the speed.

On the other hand, in general, a measurement range of up to 80 m / s is required in order to observe the ground weather observation or the ocean wind speed.

Conventionally, an ultrasonic wave-based wind speed measuring device measures a phase difference using a single ultrasonic sensor. In this case, the measurement range is 0 to 30 m / s, which makes it impossible to measure a weather observation or a sea wind speed .

A configuration in which the phase difference is measured through a plurality of ultrasonic sensors and the wind speed and the wind direction are measured based on the measured phase difference are provided as in Patent Documents 1 and 2, but a transmission sensor is provided on the upper side, It is necessary to provide a separate supporting structure for maintaining the distance between the transmitting sensor and the receiving sensor disposed up and down and to secure a certain space for the supporting structure at the time of installation.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a view showing a schematic configuration of an apparatus for measuring an air-directional wind speed using ultrasonic waves according to a first embodiment of the present invention.

As shown in FIG. 1, an ultrasonic wave sensor using an ultrasonic wave includes an ultrasonic sensor module 100 and a wind direction velocity measuring unit 200.

The ultrasonic sensor module 100 includes at least two pairs of ultrasonic transmission / reception sensors that are spaced apart from each other by a predetermined distance so that a plurality of transmission / reception sensors for transmitting and receiving ultrasonic waves are opposite to each other in the same axial direction. Preferably, the ultrasonic sensor module 100 includes first to fourth transceiving sensors 110, 120, 130, and 140. The first and second transceiving sensors 110 and 120 are spaced apart from each other by a predetermined distance in the X- The third and fourth transceiving sensors 130 and 140 are spaced apart from each other by a predetermined distance in the axial direction. At this time, the first to fourth transceiving sensors 110, 120, 130, and 140 may be arranged in four directions at an interval of 90 degrees. For example, the first transceiving sensor 110 is disposed on the east side (E), the second transceiving sensor 120 is disposed on the west side (W) to face each other on the X axis, and the third transceiving sensor 130 And the fourth transceiver sensor 140 is disposed on the north (N) side so as to face each other on the Y axis.

In addition, the ultrasonic sensor module 100 is constituted by a transmission / reception sensor capable of transmission and reception processing of ultrasonic waves, and an operation group is set so that velocity vector components of different direction axes are output in a constant period unit. At this time, the operation group of the ultrasonic sensor module 100 is divided and set according to the ultrasonic transmission / reception direction of the transceiving sensor arranged on the X axis in the horizontal direction and the transceiving sensor arranged on the Y axis in the vertical direction. That is, the number of cases of having at least one different transmission / reception direction with respect to the X axis and the Y axis through the first to fourth transmission / reception sensors 110, 120, 130, and 140 is four. Therefore, the first to fourth operation groups G1, G2, G3 , G4) can be set. For example, as shown in FIG. 2, the first group G1 is set to the transmission mode in which the second transmission / reception sensor 120 in the X-axis direction and the third transmission / reception sensor 130 in the Y-axis direction transmit ultrasonic waves, The second group G2 is set to the transmission mode in which the first transmission / reception sensor 110 in the X-axis direction and the third transmission / reception sensor 130 in the Y-axis direction transmit ultrasonic waves, and the third group G3 is set in the transmission mode The first transmission / reception sensor 110 and the fourth transmission / reception sensor 140 in the Y-axis direction are set to the transmission mode in which ultrasonic waves are transmitted, the fourth group G4 is set to the second transmission / reception sensor 120 in the X- The fourth transceiver sensor 140 on the directional axis is set to a transmission mode for transmitting ultrasonic waves and transmits ultrasonic waves corresponding to the input rectangular waves. At this time, it is a matter of course that the transmission / reception sensor disposed at the position opposite to the transmission / reception sensor set in the ultrasonic transmission mode is set to the reception mode for receiving the corresponding ultrasonic wave. Here, when ultrasonic transmission / reception is performed through the transmission / reception sensor disposed on the X-axis and the transmission / reception sensor disposed on the Y-axis, signals may be crossed at an inner central portion provided with the transmission / reception sensor. However, the transmission / reception sensor is a high- Since the angles are very narrow, mutual interference need not be considered.

 1, the wind direction and velocity measuring unit 200 includes a signal transmitting unit 210, a signal receiving unit 220, an information input unit 230, an information output unit 240, a data memory 250, and a control unit 260 .

The signal transmitter 210 generates a square wave signal having a predetermined frequency and provides the square wave signal to the ultrasonic sensor module 100. The signal transmitter 210 may correspond to the first to fourth transceivers 110, 120, 130 and 140 of the ultrasonic sensor module 100 and may be coupled to the corresponding transceiver. At this time, the signal transmitter 210 is configured to provide a square wave signal to the transmission / reception sensor based on the on / off control signal provided from the controller 260. That is, the control unit 260 sets the signal transmission unit 260 coupled to the transmission / reception sensor set to the transmission mode to the ON state, so that the ultrasonic signal is transmitted through the transmission / reception sensor set in the transmission mode. Here, the signal transmitter 210 continuously supplies a square wave to the transmitter / receiver sensor coupled to the signal transmitter 210, and controls the transmitter / receiver sensor on / off by the controller 260 so that the transmitter / It is also possible to set the ultrasonic signal to be transmitted.

The signal receiving unit 220 receives ultrasonic signals from the ultrasonic sensor module 100. The signal receiving unit 220 converts signals provided to the first to fourth transceiving sensors 100 of the ultrasonic sensor module 100 into square waves. At this time, the signal receiving unit 220 may correspond to the first to fourth transceiving sensors 110, 120, 130, 140 of the ultrasonic sensor module 100 and may be coupled to the corresponding transceiving sensors. The signal receiving unit 220 may include an amplifier (not shown) for amplifying a square-wave received signal to a predetermined level and a filter (not shown) for removing a noise component from the received signal and outputting the removed signal. That is, the signal receiving unit 220 may be configured to amplify and filter a signal provided from the ultrasonic sensor module 100, and then convert the signal into a square wave.

The information input unit 230 is for inputting various kinds of information related to the wind direction velocity, for example, the user performs operations such as changing the operation mode order of the ultrasonic sensor module 100.

The information output unit 240 is for outputting various types of information related to the wind direction wind speed, and may be configured, for example, as a display window to display and output current wind direction and wind speed information.

The data memory 250 stores various information related to the wind direction wind speed measurement. The data memory 250 stores operation mode information of the ultrasonic sensor per operation group, square wave generation information including square wave frequency and voltage level, wind speed calculation algorithm, wind direction measurement algorithm, basic setting values applied to wind speed and direction calculation, For example, the length of a moving path between the transmitting and receiving sensors, sound velocity, and the like.

The control unit 260 sets the ultrasonic sensor modules to different operation groups according to the operation modes of the plurality of transceiving sensors, sets the operation mode of the transceiving sensor to correspond to the predetermined operation group, And also calculates the current wind speed and the wind direction based on the phase difference of the signals transmitted and received through the ultrasonic sensor module 100. In addition, That is, the controller 260 calculates the velocity values corresponding to the respective motion groups based on the phase differences calculated for the first to fourth motion groups G1 to G4, The speed vector of the corresponding direction axis is calculated through the speed vector difference, and the current wind speed and the wind direction are calculated through the speed vector sum of the different direction axes.

Next, the wind direction wind speed measurement process of the controller 260 will be described in more detail with reference to FIG.

First, the control unit 260 controls the signal transmission unit 210 or the first to fourth ultrasonic sensors 110, 120, 130 and 140 based on the transmission / reception sensor operation mode of the operation group set for the ultrasonic sensor module 100, And controls the transmission / reception sensor to provide a square wave of a predetermined frequency. At this time, the transmission / reception sensor set in the transmission mode converts the square wave provided from the signal transmission unit 210 into an ultrasonic signal and transmits it to the transmission / reception sensor arranged opposite to the transmission / reception sensor.

In this state, the control unit 260 converts the reception signal of the transmission / reception sensor set in the reception mode for each operation group provided through the signal reception unit 220 into a square wave signal and compares the received signal with a transmission signal to obtain a phase difference? T (ST1). That is, the control unit 260 calculates the delay time, that is, the phase difference? T, by comparing the transmission signal with the reception signal. At this time, the phase difference? T is calculated for different direction axes for each operation group. For example, the X-axis phase difference and the Y-axis phase difference are calculated for the first to fourth operation groups, respectively.

In addition, when the phase difference calculated for the current operation group is out of a preset limit range, the controller 260 clears the phase difference information for the operation group, and does not perform processing for calculating the wind speed / direction thereafter. For example, the phase difference limit range may be set to "previously calculated phase difference +/- 20% ". This is to adaptively cope with changes in the surrounding environment by minimizing the measurement error of the wind velocity and the wind direction due to the phase difference delay caused by the change of the surrounding environment such as the temperature or the atmospheric pressure.

On the other hand, in general, the measurement of the wind speed using ultrasonic waves is based on the ultrasonic wave movement time which varies according to the air flow, and the transmission / reception phase difference? T with respect to the ultrasonic signal includes the wind direction and the wind speed information. Equation (1) is a mathematical expression representing the relationship between the wind direction represented by the phase difference (? T) and the wind speed.

Where L is the travel path length of the ultrasonic wave, C is the sound velocity, V is the wind velocity, and Φ is the angle between the movement path of the ultrasonic waves and the wind. At this time, the travel path lengths of the ultrasonic waves are the distances between the sensors arranged on the same axis on opposite sides.

Meanwhile, the controller 260 calculates a velocity value for each motion group based on the phase difference? T calculated in step ST1 (ST2). That is, the controller 260 calculates a velocity value for each direction axis in the corresponding motion group on the basis of the phase difference? T with respect to different direction axes for each motion group, Is calculated. At this time, the velocity vector of the motion group is calculated as a velocity vector for the X-axis or Y-axis according to the characteristics. For example, when the first to fourth operation groups are set to the transmission / reception sensor operation mode as shown in FIG. 4, the X and Y axis velocity values Vx1 and Vx2 in the first and second operation groups G1 and G2 And the Y-axis velocity values Vy1 and Vy2 are calculated in the third and fourth operation groups G3 and G4, respectively.

Equation (2) is a mathematical expression for calculating the wind speed based on the measured time difference? T.

That is, the controller 260 first calculates the X-axis direction velocity vector and the Y-axis direction velocity vector in the arbitrary motion group using Equation (2), and outputs the X-axis direction velocity vector and the Y- And calculates the velocity vector of the corresponding motion group through summing. In other words, the first to fourth velocity vectors (Vx1, Vx2, Vy1, and Vy2 in Fig. 6) are calculated to correspond to the first to fourth motion groups.

The controller 260 then computes the difference between the X-axis velocity values Vx1 and Vx2 and the Y-axis velocity values Vy1 and Vy2 with respect to the Y-axis direction as shown in Equation (3) Speed vector and a Y-axis axial velocity vector are calculated (ST3). That is, the controller 260 calculates the velocity vectors for the different direction axes through the velocity vector differences of the different motion groups in the same axis direction.

Equation (3) is a mathematical expression for calculating velocity vectors for different directional axes based on the velocity vector values for each motion group calculated in ST3.

Thereafter, the controller 260 calculates the current wind speed based on the velocity vector values of the different direction axes calculated in step ST3 (ST4). That is, FIG. 5 schematically shows the relationship between the velocity vector and the wind direction and the wind speed. The velocity, that is, the current wind velocity value V is calculated through the sum of the X axis velocity vector Vx and the Y axis velocity vector Vy do.

Equation (4) is a mathematical expression for calculating the magnitude of the actual wind speed based on the magnitude of the velocity vector value with respect to the directional axis.

That is, the controller 260 calculates the current wind speed value by calculating the magnitude of the wind speed vector V generated in step ST4 through Equation (4).

Also, the controller 260 calculates the current wind direction based on the angle between the velocity vectors calculated in step ST4 (ST5). The current wind direction can be expressed by an angle? With the X axis with respect to the current wind speed vector V as shown in FIG.

That is, the wind direction is calculated as the sum of the vector components of the X-axis and the Y-axis, as shown in Equation (5).
