The present application relates to a radiosonde having a light shielding part that shields a temperature sensor.

High-rise weather observations of more than 30 km above the earth's surface generally use radiosonde to monitor temperature, humidity, wind direction and wind speed. Radiosonde is equipped with a temperature sensor, humidity sensor and Global Positioning System (GPS) sensor, and the balloon rises from the ground surface to an altitude of more than 30km above the ground every month. Send to the receiver. The terrestrial receiver recalculates the temperature, humidity, wind direction, and wind velocity measurement data sent from radiosonde and converts it into various information, and the converted information is transmitted to meteorological agencies such as the Korea Meteorological Administration and used as basic data for weather forecasting.

In this regard, in general, temperature measurement in radiosonde is an important factor, and the temperature measurement is expressed by the following equation.

[Equation 1]

&Quot; (2) "

t ₀ : Temperature after insolation compensation (℃)

t: Temperature before insolation compensation (temperature measured by temperature sensor, ℃)

Δt: Solar radiation correction amount (日 射 補正 量, ℃)

K: cloud correction factor

P _st : Solar energy absorbed directly by the temperature sensor (kcal / s)

Q ₁ : The degree of heat transfer from the temperature sensor to the surrounding air and to the boom rest (kcal / sK)

Q ₂ : Heat transmitted to the temperature sensor among the solar energy absorbed by the rod and the lead wire (Kcal / s)

To sum up [Equation 1] and [Equation 2], Radiosonde temperature sensor is due to the solar radiation (日 射, Solar Radiation), the temperature measured by the temperature sensor is generally higher than the actual temperature.

By subtracting (Δt), the temperature t ₀ after solar irradiation correction can be approximated to the actual temperature.

Here, the solar radiation correction amount (Δt) is the solar energy (P _st ) absorbed directly by the temperature sensor among the various elements in [Equation 2], and in general, the estimated calculation of the solar radiation correction amount (Δt) is from 0 ° C to 5 ° C. to be. Solar energy (P _st ) is determined by the external influences of the temperature sensor and the sun's angle and clouds. It is common to calculate the solar sensor's solar angle by inputting radiosonde's uncoordinate and lift time into the high-rise weather observation system before flying radiosonde.

However, in actual raining, the radiosonde is not constantly stopped but is moving under the influence of wind and the like, and the angle of incidence with the sun may change at any time. According to the conventional calculation method, the actual amount of solar correction (Δt) This inaccuracy caused many errors in the estimated actual temperature (t ₀ ).

The humidity sensor 11 may measure the degree to which water vapor in the atmosphere (air) is included. In addition, the temperature sensor 12 may measure the temperature. 1 and 2, the boom 13 may have a plate shape or a bar shape. In addition, referring to FIG. 1, the boom 13 may have a humidity sensor arrangement slot 131 in which the humidity sensor 11 is disposed along the vertical direction. In addition, the boom 13 may include an extension member 1312 extending into the humidity sensor arrangement slot 131, the humidity sensor 11 is provided in the extension member 1312 slot for the humidity sensor arrangement. 131 may be disposed within. In addition, the boom 13 may be formed with a temperature sensor arrangement slot 132 in which the temperature sensor 12 is disposed along the vertical direction.

3 and 4, the radio sonde 1 may include a light shielding unit 16. The light blocking unit 16 may block at least a portion of the light directly incident to the temperature sensor 12 so that distortion of the measurement temperature due to the direct incident of the light to the temperature sensor 12 is reduced.

In general, temperature measurement in radiosonde is an important factor, and the temperature measurement is expressed by the following equation.

[Equation 1]

&Quot; (2) "

t ₀ : Temperature after insolation compensation (℃)

t: Temperature before insolation compensation (temperature measured by temperature sensor, ℃)

Δt: Solar radiation correction amount (日 射 補正 量, ℃)

K: cloud correction factor

P _st : Solar energy absorbed directly by the temperature sensor (kcal / s)

Q ₁ : The degree of heat transfer from the temperature sensor to the surrounding air and to the boom rest (kcal / sK)

Q ₂ : Heat transmitted to the temperature sensor among the solar energy absorbed by the rod and the lead wire (Kcal / s)

To sum up [Equation 1] and [Equation 2], Radiosonde temperature sensor is due to the solar radiation (日 射, Solar Radiation), the temperature measured by the temperature sensor is generally higher than the actual temperature. In order to minimize the distortion of the measured temperature (t) of the temperature sensor under the influence of solar radiation, the solar radiation correction amount (Δt) is calculated in various ways, and the solar radiation correction amount is measured by the temperature t measured by the temperature sensor as shown in Equation 1. By subtracting (Δt), the temperature t ₀ after solar irradiation correction can be approximated to the actual temperature.

Here, the solar radiation correction amount (Δt) is the solar energy (P _st ) absorbed directly by the temperature sensor among the various elements in [Equation 2], and in general, the estimated calculation of the solar radiation correction amount (Δt) is from 0 ° C to 5 ° C. to be. Solar energy (P _st ) is determined by the external influences of the temperature sensor and the sun's angle and clouds. It is common to calculate the solar sensor's solar angle by inputting radiosonde's uncoordinate and lift time into the high-rise weather observation system before flying radiosonde.

That is, in the related art, the radiosonde temperature sensor of high-rise weather observation needs to be compensated for the measured value of the temperature sensor raised by the solar radiation effect, and most radiosonde manufacturers calculate the solar radiation correction amount Δt by software. . The conventional software method is a method of calculating the radiosonic coordinates and the non-polarization time of the radiosonde into the observation data processing system 1400 in advance before the flysoning. Through the previously input non-coordinates and non-lifting time, the solar energy and the radiosonde temperature sensor predict the solar radiation angle and solar radiation to calculate the solar energy (P _st ). However, the calculation result of the solar energy Pst through such prediction causes errors due to unpredictable irregular movement and movement due to meteorological changes such as clouds, wind direction, wind speed, and rainfall, and consequently, the solar radiation correction amount (Δt). ) And the actual temperature (t ₀ ) causes a large error.

In other words, the solar radiation correction amount Δt for correcting the solar radiation effect in the radiosonde of high-rise weather observation is largely due to the solar energy P _st absorbed directly by the temperature sensor as shown in Equation 2 above. Is determined. In addition, the solar energy (P _st ) is an important factor of the temperature of the radiosonde and the angle of the solar radiation. However, the actual solar insolation angle is calculated by inputting radiosonde's uncoordinate coordinates and liftover time into the high-rise weather observation system before flying radiosonde. Not in a stationary state, but moving under the influence of wind, etc., the sun angle with the sun may change from time to time. As the temperature of the Sunson temperature sensor and the sun's solar angle change frequently, many types of radiosonde manufacturers conventionally try to solve the software by calculating the solar radiation correction amount Δt. ), The actual solar radiation compensation (Δt) is not accurate, and many errors may occur in the actual temperature (t ₀ ). That is, the conventional radiosonde cannot predict the radiosonde's movement (especially rotation) in the process of calculating the solar radiation correction amount Δt due to the solar solar energy P _st , so the actual solar radiation correction amount Δt is not accurate. There was a disadvantage that a lot of error occurs in the temperature (t ₀ ).

In contrast, the present radiosonde 1 includes a light shielding portion 16, so that the temperature sensor 12 directly absorbs the sun's solar energy P _st , or the temperature sensor 12 is irradiated. By preventing energy from being absorbed directly, the solar radiation correction amount Δt becomes a very small value, thereby making the measured temperature t of the temperature sensor 12 approximate to the actual temperature t ₀ , thereby remarkably reducing the error compared to the conventional radiosonde. Can be reduced. That is, this radio sonde 1 can solve the conventional disadvantage by providing (installing) the light shielding part 16 with respect to the temperature sensor 12 so that the temperature sensor 12 may not be affected by the solar radiation.

That is, the present radiosonde 1 provides a light shielding portion 16 to the temperature sensor 12, thereby preventing at least a part of the solar energy P _st of the sun from acting to reduce the solar radiation correction amount Δt or zero. By approximating to, by making the measured temperature t of the temperature sensor 12 approximate to the actual temperature t ₀ , the occurrence of errors can be reduced or prevented.

In addition, the light blocking unit 16 may serve to physically protect the temperature sensor 12 or to protect from electric shock.

The front light blocking plate protrudes from the front light blocking plate 161 and the upper and lower portions of the front light blocking plate 161 which are spaced apart from the temperature sensor 12 at the front of the temperature sensor 12, and are connected to the boom 13. It may include a bridge (bridge) 162. 4 and 6, the bridge 162 may extend rearward from the front light blocking plate 161 and be connected to (eg, attached to) the boom 13. For example, two bridges 162 may be provided at an upper side of the front light blocking plate 161 and two may be provided at a lower side thereof. Accordingly, the front light blocking plate may include four bridges 162.

4 to 7, the light blocking unit 16 may include a rear light blocking plate. The rear light blocking plate protrudes from the upper and lower portions of the rear light blocking plate 161 and the rear light blocking plate 161 which are spaced apart from the temperature sensor 12 at the rear of the temperature sensor 12 and connected to the boom 13. It may include a bridge 162. 4 and 6, the bridge 162 may extend forward from the rear light blocking plate 161 and be connected to (eg, attached to) the boom 13. In addition, for example, two bridges 162 may be provided at an upper side of the rear light blocking plate 161 and two may be provided at a lower side thereof. Accordingly, the rear light blocking plate may include four bridges 162.

In addition, referring to FIG. 4, the front light blocking plate 161 and the rear light blocking plate 161 are disposed to be spaced apart from the temperature sensor 12 in the front-rear direction so that the front light blocking plate 161 and the rear light blocking plate 161 are disposed. An external and open space 163 may be formed therebetween. According to the open space 163, air permeability into and out of the light shielding portion 161 is secured, so that air flows into and out of the light blocking portion 161.

In addition, the front light blocking plate and the rear light blocking plate may be a material including plastic. Alternatively, the front light blocking plate and the rear light blocking plate may be formed of aluminum or copper. In addition, the front light blocking plate and the rear light blocking plate may be plate-shaped (thin form), it may be manufactured in the form of being injected. Accordingly, the front and rear light blocking plates may be plate plastic, plate aluminum, or copper plate. In addition, when the material constituting the front light shielding plate and the rear light shielding plate includes plastic, the bridge 162 is connected (attached) to the boom 13 by an adhesive (refer to FIG. 3 and FIG. 6 together). Reference numeral 1621). In addition, when the material constituting the front light shielding plate and the rear light shielding plate includes aluminum or copper, the bridge 162 may be connected (attached) to the boom 13 by soldering (the part to be connected is indicated by reference numeral 1621). have. In addition, a coating agent may be applied to surfaces of the front light blocking plate and the rear light blocking plate. The coating may be for reflection of solar radiation. In addition, the coating agent may minimize the transmission of solar energy P _st by the sun to the temperature sensor 12. For this purpose, the coating agent may be silver or the like.

In summary, the present radiosonde 1 may include a light shielding portion so that the temperature sensor 12 can block the solar energy P _st absorbed directly by the sun, and according to the light shielding portion, solar radiation Absorption amount of energy P _st directly absorbed by the temperature sensor 12 can be reduced, so that the solar radiation correction amount Δt in Equations 1 and 2 is reduced to become a very small value, or 0 Since it can be approximated to, the error can be significantly reduced compared to the conventional radiosonde measurement method. In addition, the present radio sonde (1) has a front (shield) and the rear shielding plate is provided with a distance (a constant distance) to the temperature sensor 12 for the ventilation of the temperature sensor 12, it is possible to smooth the flow of air. . In addition, the light blocking unit 16 may serve to physically protect the temperature sensor 12 or to protect from electric shock.

In addition, referring to FIGS. 3 and 4, the radio sonde 1 may include a solar panel 17 provided on an outer surface of the light shielding unit 16 to generate a voltage from incident light. In addition, the radio sonde 1 may include a control unit, the control unit is a voltage received from the solar panel 17, the temperature measurement information distorted due to any one of conduction, convection, and radiation of heat from the light blocking unit 16 Correction can be made based on measurement information.

The temperature sensor 12 may receive heat (any one of conduction, convection, and radiation) from the light blocking unit 16. The temperature measured by the temperature sensor 12 by the heat transfer may be a temperature sensor 12. It may be higher than the temperature actually measured at the point where. Accordingly, temperature correction in consideration of heat transfer to the temperature sensor 12 may need to be made. On the other hand, the control unit of the present radio zone 1 calculates a correction amount in consideration of the heat energy transmitted to the temperature sensor 12 by the light incident on the light shielding portion 16, and the temperature sensor 12 measures the correction amount in consideration of the correction amount. One temperature can be corrected. For example, the correction amount may be calculated from the voltage measurement information and a look-up table of the amount of heat energy transferred from the light shielding portion 16 to the temperature sensor 12. In addition, the controller can calculate the corrected temperature t ₀ by subtracting the correction amount from the temperature measured by the temperature sensor 12. Further, for example, the voltage measurement information may be generated for a voltage amount generated during a preset time, a maximum value of the voltage amount generated within a preset time, a minimum value of the voltage amount generated within a preset time, and a predetermined time. It may include an average value of the voltage amount.

For example, the radiosonde 1 performs the voltage measurement step of the solar panel 15 for a predetermined time, calculates the maximum value, the minimum value and the average value of the voltage measurement value and generates voltage measurement information including the same. Based on the measurement information, a step of calculating a heat (heat energy) value transferred to the temperature sensor 12 through a look-up table of the voltage value and the heat transferred to the temperature sensor 12 may be performed. Based on the calculated values and weather data such as temperature, humidity, and wind direction measured by the radiosonde, the correction amount can be calculated using a look-up table or an equation through experiments. . The actual temperature t ₀ can then be estimated.

As described above, the thermal energy transmitted to the temperature sensor 12 through the light shielding unit 16 is not a conventional software calculation method, but is provided through the solar panel (solar panel) 17 mounted to the light shielding unit 16. By measuring, the error of the calculated temperature (t ₀ ) can be advantageously reduced significantly compared to the conventional measuring method.

8 and 9, the radiosonde 1 may include a solar panel (solar panel) 15. The solar panel 15 may be provided adjacent to the temperature sensor 12 to have an incident amount of light corresponding to the incident amount of light to the temperature sensor 12. That the incident amount of light to the solar panel 15 and the incident amount of light to the temperature sensor 12 correspond to the incident amount of light to the solar panel 15 and the incident amount of light to the temperature sensor 12 within a predetermined error range. It can mean something similar. In addition, for example, when the incident of light by the light shielding portion 16 is not blocked at the source (for example, the temperature sensor 12 through the open space 163 for ensuring breathability into the light shielding portion 161) May be generated.) The solar panel 15 may be provided to have an incident amount of light corresponding to an incident amount of light to the temperature sensor 12 generated as described above.

In addition, the solar panel 15 may generate a voltage from incident light. In addition, the controller may correct the temperature measurement information based on the voltage measurement information received from the solar panel 15. The temperature measured by the temperature sensor 12 due to the solar radiation effect on the temperature sensor 12 may be higher than the actual temperature to be measured at the point where the temperature sensor 12 is located. Accordingly, it may be necessary to make a temperature correction in consideration of the solar radiation effect on the temperature sensor 12. On the contrary, the radio zone 1 has a solar panel based on information related to a voltage generated by the solar panel 15 which is provided to have the incident amount of light corresponding to the incident amount of light to the temperature sensor 12. The amount of light incident on the temperature sensor 12 corresponding to the amount of light incident on the light 15 is calculated, that is, the solar radiation influence information on the temperature sensor 12 is calculated and based on the temperature measured by the temperature sensor 12. By calibrating the temperature at the point where the temperature sensor 12 is located (calculated temperature) can be calculated. For reference, according to the above correction of the control unit, when the light blocking unit 16 is not cut off, that is, the incident of the light incident to the temperature sensor 12, the error of the measurement temperature that may occur Can be corrected.

Specifically, in order to improve the disadvantages of the prior art, the radiosonde 1 calculates voltage measurement information of the voltage produced by the solar panel 15 described above, and enters the temperature sensor 12 through the voltage measurement information. The temperature measured by the temperature sensor 12 may be corrected in consideration of the solar radiation correction amount Δt due to light. In other words, the present radiosonde 1 may include a solar panel 15, and the solar panel 15 may convert solar radiation into a voltage and provide it to the control unit, and the solar panel 15 may be provided. According to the output voltage of), the control unit calculates the solar radiation amount and solar correction amount Δt using the solar correction algorithm described below, and calculates the temperature t ₀ after the solar correction as the actual temperature.

Specifically, the control unit may calculate the solar radiation amount through the voltage measurement information and the look-up table of the solar radiation amount, the calculated solar radiation amount, and weather such as temperature, humidity, and wind direction measured by the radiosonde 1. The solar radiation correction amount (Δt) is calculated from a look-up table based on the data or an experimental equation, and is corrected by subtracting the solar radiation correction amount (Δt) calculated from the temperature measured by the temperature sensor 12. Calculated temperature can be calculated. For reference, the voltage measurement information includes a voltage amount generated during a preset time, a maximum value of the voltage amount generated within a preset time, a minimum value of the voltage amount generated within a preset time, and a voltage amount generated during a preset time. It may include an average value.

For example, referring to FIG. 14, the radiosonde 1 performs the voltage measuring step S10 of the solar panel 15 for a predetermined time, calculates the maximum value, the minimum value, and the average value of the voltage measurement value. Generating voltage measurement information, and calculating the solar radiation amount through the look-up table of the voltage value and the solar radiation amount based on the voltage measurement information (S20), and the calculated solar radiation amount and the present radio Based on the meteorological data such as temperature, humidity, and wind direction measured in the sonde (1), a step (S30) of calculating a solar radiation correction amount Δt by a look-up table or an experiment may be performed. . Thereafter, the actual temperature t ₀ may be calculated (S40).

As described above, the radiosonde 1 calculates the solar radiation amount and the solar radiation correction amount Δt through the voltage measurement information of the solar panel 15 by using an algorithm for calculating the solar radiation amount and the solar radiation correction amount Δt. Can calibrate the measured temperature. Since the solar radiation amount and the solar radiation correction amount Δt need to consider the amount of light incident on the temperature sensor 12, the solar panel 15 measures the incident amount of light corresponding to the incident amount of light to the temperature sensor 12 as described above. It is preferable to be provided adjacent to the temperature sensor 12 to have.

In summary, the conventional radio zone has a structure in which the signal measured by the temperature sensor and the humidity sensor of the boom is sent to the radio zone control module through the connection part, and the temperature sensor has the solar radiation compensation amount by the mathematical calculation equation. Δt is calculated to approximate the temperature t ₀ after solar correction to the actual temperature. However, according to this, since the radiosonde temperature sensor calculates the solar radiation correction amount Δt due to the solar solar energy P _st , since the movement and the movement path of the radiosonde cannot be predicted, the actual solar radiation correction amount Δt This may not be accurate and may cause a disadvantage that a large amount of error occurs in the actual temperature t ₀ .

On the other hand, the present radio zone 1 may include a solar panel 15, the solar panel 15 may convert the solar radiation into a voltage (Voltage) to provide to the control unit, the solar panel 15 According to the output voltage of), the control unit calculates the solar radiation amount and solar correction amount Δt using the algorithm of the present radiosonde 1 as described above, and calculates the temperature t ₀ after solar correction as the actual temperature. As such, the radiosonde 1 directly measures the solar energy P _st absorbed by the temperature sensor 12 with the solar panel 15, and the solar energy P _st and the solar radiation correction amount ( By calculating [Delta] t), it is possible to significantly reduce the error caused by the irregular movement and the movement path, which is a conventional disadvantage.

That is, according to the above, the radio sonde 1 is not a conventional software calculation method, but instead of a solar panel (solar panel) 15 mounted on the boom 13 with actual solar energy P _st . By measuring through, the actual movement and the movement path of the present radiosonde (1) can be reflected, the solar radiation correction amount (Δt) and the actual temperature (t ₀ ) can have the advantage that the error is significantly reduced than the conventional measurement method. . That is, the radiosonde (1) is to improve the solar radiation correction amount (Δt) of the conventional radiosonde temperature sensor, it is possible to reduce the error between the actual temperature (t _0).

3, 4, 8, and 9, the radiosonde 1 includes a protective cap 14 surrounding at least a part of the humidity sensor 11.

For example, referring to FIG. 10, the protective cap part 14 includes a cap 141 surrounding the humidity sensor 11 at intervals except for the lower side of which the lower side is opened. Accordingly, the air (fluid) is introduced into the cap 141 through the opened lower side, the humidity sensor 11 can measure the humidity in the air, and at the same time, the humidity sensor 11 is atmospheric air by the cap 141 Direct contact with the liquid in water (such as water) can be prevented.

In general, when radiosonde is lifted from the surface of the earth, it rises in the atmosphere and passes through high humidity sections such as cloud layers, and water may directly contact the humidity sensor in such a high humidity section. Therefore, a countermeasure is required to prevent this.

By the way, according to the present radiosonde, the humidity sensor can be protected from the liquid (such as rain) by the cap 141, and at least a part of the fluid (air) flowing through the opened lower side of the cap 141 It can be leaked to the outside through the vent 1411 to form a smooth air flow to the inside and outside the cap 141 and to ensure high breathability, in addition, the upper side of the vent 1411 is closed but the The lower portion may be provided with a cover 142 to open, so that the smooth movement of air into and out of the cap 141 is allowed and can prevent the inflow of liquid into the cap 141 through the vent 1411. Accordingly, an improved reaction speed of the humidity sensor 1 according to smooth air movement may be secured while protecting the humidity sensor 1, and an error of humidity measurement may be reduced as compared with the conventional art.

3 and 8, as described above, the humidity sensor 11 slot 131 on which the humidity sensor 11 is disposed may be formed in the boom 13 along the vertical direction. In addition, the cap 141 may be disposed surrounding the humidity sensor 11 in the slot 131 for the humidity sensor arrangement. 3 and 8, protrusions 1311 protruding toward the cap 141 may be formed on both inner surfaces of the slot 131 for the humidity sensor arrangement. 3, 4, 8, and 10 to 12, the outer surface of the cap 141 protrudes from the outer surface of the cap 141 toward the protrusion 1311 and engages with the protrusion 1311. A connection portion 1412 in which the engagement groove 14121 (see FIG. 12) is formed may be provided.
