The present invention relates to a radio sonde having a solar panel for solar radiation correction of a temperature sensor.

In high-altitude meteorological observations over 30 km above the surface, temperature, humidity, wind direction and wind speed are generally observed using radiosonde. The radiosonde is equipped with a temperature sensor, a humidity sensor and a global positioning system (GPS) sensor. It measures the temperature, humidity, wind direction and wind speed in real time from the surface of the balloon to the altitude above 30 km from the ground. Lt; / RTI > The terrestrial receiver recalculates the temperature, humidity, wind direction and wind speed measurement data sent from the radiosonde and converts it into various kinds of information. The converted information is transmitted to meteorological organizations such as the Korea Meteorological Administration and used as basic data for weather forecast.

In this regard, in general, the temperature measurement in the radio-sonde is an important factor, and the temperature measurement value is expressed by the following equation.

[Equation 1]

t ₀ : temperature after solar radiation correction (캜)

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

Δt: solar radiation correction amount (sunshine correction amount, ° C)

K: correction coefficient of cloud (correction coefficient)

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

Q ₁ : The degree of heat transfer (kcal / s ㆍ K) from the temperature sensor to the ambient air and heat conduction to the boom lobe is easy.

Q ₂ : Of the solar energy absorbed by the rod and lead, the heat (Kcal / s) transferred to the temperature sensor

Summarizing the equations (1) and (2), it is general that the temperature measured by the temperature sensor is higher than the actual temperature due to the influence of the solar radiation (sun radiation) of the radiosonded temperature sensor. In order to minimize the distortion of the temperature t measured by the temperature sensor due to the influence of the solar radiation, the solar radiation correction amount? T is calculated by various methods, and the temperature t measured by the temperature sensor subtracting the (Δt), it is possible to approximate the temperature (t ₀₎ after the correction to the actual temperature of the solar radiation.

Here, the solar radiation correction amount (Δt) is the solar radiation energy (P _st ) directly absorbed by the temperature sensor in most of the various elements in [Equation 2], and the estimated value of the solar radiation correction amount (Δt) to be. The solar radiation energy (P _st ) is determined by the external influences of the temperature sensor and the solar radiation angle and the cloud. The temperature sensor and the angle of solar radiation are usually calculated by inputting the radiosonde 's constellation coordinates and flight time into the high - rise weather observation system before flying the radiosonde.

However, according to the conventional calculation method, the actual solar radiation correction amount [Delta] t can not be obtained because the radiosonde is moved by the effect of wind or the like, (T ₀ ), which is not accurate, has a side in which a lot of errors are generated.

The background technology of the present application is disclosed in Korean Utility Model Registration Utility Model No. 10-1817893.

The term (upper, upper, lower, lower, front, rear, and the like) related to directions and positions in the description of the embodiments of the present application is set based on the arrangement state of each structure shown in the drawings. 1, for example, the 12 o'clock direction is generally on the upper side, the portion facing the 12 o'clock direction on the whole is the upper side, the 6 o'clock side is on the lower side in general, . 2, 4, and 11, the 9 o'clock direction can be generally forward, and the 3 o'clock direction as a whole can be rearward or the like.

We are talking about radio-sonde.

Hereinafter, a radio sonde (hereinafter referred to as " present radiosonde 1 ") according to an embodiment of the present invention will be described.

1 and 2, the radio sonde 1 includes a boom frame 13 provided with a humidity sensor 11 and a temperature sensor 12. [ The humidity sensor 11 can measure the degree of inclusion of water vapor in the air (air). Further, the temperature sensor 12 can measure the temperature. 1 and 2, the float 13 may be a plate or bar. 1, a humidity sensor arrangement slot 131 in which the humidity sensor 11 is disposed may be formed along the vertical direction on the float 13. The boom table 13 may include an extension member 1312 extending into the humidity sensor placement slot 131 and the humidity sensor 11 may be provided in the extension member 1312 in the form of a slot for humidity sensor placement (Not shown). In addition, a slot 132 for temperature sensor arrangement in which the temperature sensor 12 is disposed may be formed along the vertical direction on the float 13.

3 and 4, the radio sonde 1 may include a solar panel 15. The solar panel 15 may be provided adjacent to the temperature sensor 12 so as to have an incident amount of light corresponding to the incident amount of light to the temperature sensor 12. [ The reason that the incident amount of light to the solar panel 15 corresponds to the incident amount of light to the temperature sensor 12 is that the incident amount of the light to the solar panel 15 and the incident amount of the light to the temperature sensor 12 are the same within a predetermined error range It can mean similar.

In addition, the solar panel 15 can generate a voltage with incident light. The radio sonde 1 may include a control unit. The control unit may correct the temperature measurement information based on the voltage measurement information received from the solar panel. The temperature measured by the temperature sensor 12 due to the sun's solar influence on the temperature sensor 12 may be higher than the temperature actually measured at the point where the temperature sensor 12 is located. Accordingly, it may be necessary to perform temperature correction considering the solar radiation effect of the temperature sensor 12. On the other hand, the radiosondes 1 are arranged in a manner such that the solar panel 15, which is provided so as to have an incident amount of light corresponding to the incident amount of light to the temperature sensor 12, That is, the incident amount of light to the temperature sensor 12 corresponding to the amount of light incident on the temperature sensor 15, that is, the solar radiation influence information on the temperature sensor 12, (Corrected temperature) to be actually measured at a position where the temperature sensor 12 is located. This will be described in more detail below.

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

[Equation 1]

&Quot; (2) "

t ₀ : temperature after solar radiation correction (캜)

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

Δt: solar radiation correction amount (sunshine correction amount, ° C)

K: correction coefficient of cloud (correction coefficient)

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

Q ₁ : The degree of heat transfer (kcal / s ㆍ K) from the temperature sensor to the ambient air and heat conduction to the boom lobe is easy.

Q ₂ : Of the solar energy absorbed by the rod and lead, the heat (Kcal / s) transferred to the temperature sensor

Summarizing the equations (1) and (2), it is general that the temperature measured by the temperature sensor is higher than the actual temperature due to the influence of the solar radiation (sun radiation) of the radiosonded temperature sensor. In order to minimize the distortion of the temperature t measured by the temperature sensor due to the influence of the solar radiation, the solar radiation correction amount? T is calculated by various methods, and the temperature t measured by the temperature sensor subtracting the (Δt), it is possible to approximate the temperature (t ₀₎ after the correction to the actual temperature of the solar radiation.

Here, the solar radiation correction amount (Δt) is the solar radiation energy (P _st ) directly absorbed by the temperature sensor in most of the various elements in [Equation 2], and the estimated value of the solar radiation correction amount (Δt) to be. The solar radiation energy (P _st ) is determined by the external influences of the temperature sensor and the solar radiation angle and the cloud. The temperature sensor and the angle of solar radiation are usually calculated by inputting the radiosonde 's constellation coordinates and flight time into the high - rise weather observation system before flying the radiosonde.

In other words, conventionally, the radio-sonde temperature sensor of the high-rise meteorological observation needs to compensate the measured value of the temperature sensor which is raised by solar radiation effect by sun, and most radiosonde manufacturers calculate the solar radiation correction amount (t) by software . The conventional software-based method is a method of calculating the yarding coordinates of the radio-sonde and the time of the yarding in advance before inputting the radio-sonde into the observation data processing system 1400 before flying. The radiation energy (P _st ) is calculated by predicting the solar radiation angle and the radiation dose of the sun and the radio zone temperature sensor through the pre-input visibility coordinates and the irradiation time. Incidentally, the calculation result of the solar radiation energy Pst through such a prediction causes an error due to irregular movement and movement due to unpredictable weather changes such as clouds, wind direction, wind speed, rainfall, and the like. As a result, ) And the actual temperature (t ₀ ).

The present radiosonde 1 calculates the voltage measurement information of the voltage produced by the above-described solar panel 15 to improve the disadvantages of the related art, It is possible to correct the temperature measured by the temperature sensor 12 by calculating and considering the solar radiation correction amount DELTA t. In other words, the radio sonde 1 may include a solar panel 15, and the solar panel 15 may convert the amount of solar radiation by the sun into a voltage and provide the voltage to the control unit. The controller can calculate the solar radiation amount and the solar radiation correction amount? T by using the solar radiation correction algorithm described below and calculate the temperature (t ₀ ) after the solar radiation correction as the actual temperature.

Specifically, the control unit can calculate the solar radiation amount through the voltage measurement information and the look-up table of the solar radiation amount. The control unit calculates the solar radiation amount based on the calculated solar radiation amount and the weather (temperature, humidity, The solar radiation correction amount? T is calculated from a look-up table based on data or an experiment, and the solar radiation correction amount? T calculated at the temperature measured by the temperature sensor 12 is subtracted from the formula Can be calculated. For reference, the voltage measurement information includes a voltage amount generated during a predetermined time, a maximum value of a voltage amount generated within a predetermined time, a minimum value of a voltage amount generated within a predetermined time, And may include an average value.

For example, referring to FIG. 5, the radiosonde 1 performs the voltage measurement step S10 of the solar panel 15 for a predetermined time, calculates a maximum value, a minimum value, and an average value of the voltage measurement values, (S20) of calculating the solar radiation amount through a look-up table of the voltage value and the solar radiation amount based on the voltage measurement information, It is possible to perform a step S30 of calculating a solar radiation correction amount? T using a look-up table or an experiment based on weather data such as temperature, humidity, and wind direction measured by the sonde 1 . Thereafter, the actual temperature t ₀ can be calculated (S40).

Thus, the radiosonde 1 calculates the solar radiation amount and the solar radiation correction amount? T through the voltage measurement information of the solar panel 15 by using the algorithm for calculating the solar radiation amount and the solar radiation correction amount? T, ) Can be corrected. The amount of incident light of the light corresponding to the incident amount of light to the temperature sensor 12 is set to be smaller than the incident amount of incident light to the temperature sensor 12, It is preferable that the temperature sensor 12 is provided adjacent thereto.

In summary, the conventional radio-sonde has a structure in which signals measured through a temperature sensor and a humidity sensor of a boom zone are sent to a radio zone control module via a connection section, and the temperature sensor detects the solar radiation effect by the sun by a mathematical calculation formula (T) is calculated and the temperature (t ₀ ) after the solar radiation correction is approximated to the actual temperature. According to this, in the process of calculating the solar radiation correction amount? T due to the solar radiation energy P _st of the radiosonde, the movement and travel path of the radio sonde can not be predicted, Is not accurate and there is a disadvantage that a large error occurs in the actual temperature t ₀ .

On the other hand, the radio sonde 1 may include a solar panel 15, the solar panel 15 may convert the amount of solar radiation by the sun into a voltage and provide the voltage to the control unit, and the solar panel 15 in accordance with the output voltage of the) control unit may use an algorithm of the radiosonde (1) above to calculate the solar radiation and the solar radiation correction amount (Δt) of the sun to calculate the temperature (t ₀₎ after the correction to the actual temperature of the solar radiation. The radiosonde 1 directly measures the solar radiation energy P _st absorbed by the temperature sensor 12 with the solar panel 15 and calculates the solar radiation energy P _st and the solar radiation correction amount DELTA t), it is possible to remarkably reduce irregular motions, which are disadvantages of the prior art, and errors due to movement paths.

That is, according to the above-mentioned bar, to the radiosonde (1) is not the conventional process software of calculation, a solar panel (solar panel) mounting the actual solar energy (P _st) of the sun on the boom (13) (15) It is possible to reflect the movement and the movement path of the actual radio zone 1 and to have an advantage that the solar radiation correction amount t and the actual temperature t ₀ are significantly reduced compared to the conventional measurement method . That is, the present radiosonde 1 improves the solar radiation correction amount? T of the conventional radio-sonde temperature sensor and can reduce the error of the actual temperature t ₀ .

3 and 4, the radio sonde 1 includes a protective cap portion 14 surrounding at least a portion of the humidity sensor 11. [

For example, referring to FIG. 6, the protective cap portion 14 includes a cap 141 that surrounds the humidity sensor 11 at intervals except the lower side where the lower side is opened and opened. As a result, the humidity sensor 11 can measure the humidity in the atmosphere by flowing air (fluid) through the opened lower side into the cap 141. At the same time, the humidity sensor 11 It is possible to prevent direct contact with a liquid (e.g., water) in the liquid.

Generally, when the radiosonde is flying from the surface of the earth, the atmosphere rises and passes through a high humidity section such as a cloud layer. In such a high humidity section, water may directly contact the humidity sensor Therefore, it is necessary to take measures to prevent this.

However, according to the present radiosondes, 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 is possible to ensure smooth air flow to the inside and the outside of the cap 141 and to ensure high air permeability. In addition, since the upper side of the air vent 1411 is closed, but the air vent 1411 The lower portion can be provided with an opening lid 142 so that smooth movement of air into and out of the cap 141 is allowed and the inflow of liquid into the cap 141 through the vent 1411 can be prevented. Accordingly, an improved reaction speed of the humidity sensor 1 due to smooth air movement while protecting the humidity sensor 1 can be secured, and the error of humidity measurement compared to the conventional one can be reduced.

Referring to FIG. 3, as described above, the humidity sensor accommodation slot 131 in which the humidity sensor 11 is disposed may be formed along the vertical direction on the float 13. Further, the cap 141 may be disposed surrounding the humidity sensor 11 in the slot 131 for humidity sensor placement. 3, protrusions 1311 protruding toward the cap 141 may be formed on the inner surfaces of both sides of the humidity sensor arrangement slot 131. [ 3 and 6 to 8, an engaging groove 14121 protruding from the outer surface of the cap 141 toward the protrusion 1311 and engaged with the protrusion 1311 is formed on the outer surface of the cap 141 (See FIG. 8) may be formed. Accordingly, the engagement of the projections 1311 with the engagement grooves 14121 allows the cap 141 to be spaced apart from the humidity sensor 11.

6, 7, and 9, a vent hole (ventilation hole) 1411 through which at least a portion of the fluid (air) flowing through the opened lower side is passed through is formed in the side surface of the cap 141 do. Accordingly, an air circulation path through which the fluid (air) flowing through the opened lower side flows out of the cap 141 through the vent hole 1411 can be formed. Accordingly, the air permeability in the cap 141 can be improved as compared with the conventional one. 6, 7, and 9, the vent 1411 may be formed on the upper side of the cap 141. Accordingly, the air (fluid) flowing through the opened lower side may have a movement path that flows outward through the vent hole 1411 formed in the upper side of the cap 141 across the inside of the cap 141. Accordingly, the inflow and outflow of the fluid associated with the opened lower side can be more effectively induced, and the air permeability can be further improved.

6, 7, and 9, the protective cap portion 14 is disposed outside the ventilation hole 141, and the space formed between the ventilation hole 1411 and the ventilation hole 1411 The upper portion is closed and the cover 142 is provided such that the lower portion of the vent 1411 is opened. Since the cover 142 can be closed on the upper side of the vent 1411 and opened on the lower side of the vent 1411, it is possible to prevent the inflow of liquid (such as rain) into the vent 1411 (Airflow) of air from the vent 1411 to the outside can be allowed. Thus, the space between the lid 142 and the vent hole 1411 can form a passage through which the air moves, particularly, the air in the protective cap portion 14 flows out.

Referring to FIG. 8, one or more ventilation holes 1411 may be provided, and a lid 142 may be provided for each of the ventilation holes 1411. In other words, the plurality of ventilation holes 1411 and the cover 142 may be provided.

In addition, the protective cap portion 14 may be an extruded plastic material or a plated one.

The protective cap portion 14 of the radio sonde 1 can prevent the liquid from flowing into the cap 141 and the vent 1411 in which the vent 1411 is formed, Since the direct contact of the liquid to the humidity sensor 11 in the cap 141 is prevented and the contact of the humidity sensor 11 with the air is allowed The humidity sensor 11 can measure the humidity in the atmosphere while being protected and at the same time the air introduced into the cap 141 can flow out through the vent hole 1411, The air flow in the cap 141 can be smoothly formed, the reaction speed of the humidity sensor 11 can be improved, and the reaction speed can be improved as compared with the conventional method Accordingly, the error of the humidity measurement can be reduced.

That is, according to the present radio zone 1, the air permeability of the protection cap portion 14 can be ensured and smooth air flow to the humidity sensor 11 inside the cap 141 of the outside air in the atmosphere can be formed, As the air flow to the humidity sensor 11 is activated, the reaction speed of the humidity sensor 11 can be improved and the humidity measurement error can be reduced. Furthermore, according to the above description, since the protection cap portion 14 can be easily provided in a general radio-sonde, the disadvantage of the conventional radio-sonde can be improved with a simple structure.

In addition, the present radiosonde 1 can be manufactured in a conventional manner, and therefore radio-sonde can be realized which improves the disadvantages of the conventional radio-sonde while maintaining the manufacturing cost and manufacturing process similar to the conventional one . For example, since the protective cap portion 14 can be manufactured through a process of injecting a general plastic material and plating the surface with silver or gold, the manufacturing cost of the radiosonde 1 (protective cap portion 14) And mass production is possible. In other words, this radiosonde (1) can be regarded as a humidity sensor protection cap considering production cost and manufacturing process.

10 and 11, the radiosondes 1 may include a light shielding portion 16. As shown in FIG. The light shielding portion 16 can block at least part of the light directly incident on the temperature sensor 12 so as to reduce the distortion of the measured temperature caused by the direct incidence of the light to the temperature sensor 12. [

As described above, In order to correct the solar radiation incident by the sun in the radio zone, the solar radiation correction amount (Δt) is the sum of the solar radiation energy directly absorbed by the temperature sensor (P_st).  Also, solar energy (P_st) Is an important factor for the temperature of the radiosonde and the angle of solar radiation. However, the actual solar angle of the sun is calculated by inputting to the high-rise meteorological observation system the yarding coordinates and the yarding time of the radiosonde before the flying, It is not the state where it is stopped, but is influenced by the wind and the like, and the angle with the sun can be changed from time to time. As such, since the temperature sensor of the radiosonde and the solar radiation angle of the sun change from time to time, many types of radiosonde manufacturers have tried to solve the solar radiation correction amount Δt in a software way, ), The actual solar radiation correction amount? T is not accurate and the actual temperature t₀) Could be generated. That is, the conventional radio-sonde has the solar radiation energy P_stThe rotation of the radio zone can not be predicted in the process of calculating the solar radiation correction amount t because of the fact that the actual solar radiation correction amount t is not accurate and the actual temperature t₀), Which causes a lot of errors.

On the other hand, the present radiosonde 1 includes the light shielding portion 16 to reduce the absorption amount by which the temperature sensor 12 directly absorbs solar radiation energy P _st , By making the solar radiation correction amount DELTA t be a very small value by preventing the energy directly from being absorbed so that the measured temperature t of the temperature sensor 12 is approximated to the actual temperature t ₀ , Can be significantly reduced. That is, the present radiosonde 1 can solve the conventional disadvantages by providing (installing) the light shield portion 16 to the temperature sensor 12 so that the temperature sensor 12 is not affected by sunlight.

That is, the radiosonde 1 provides the light shield 16 to the temperature sensor 12 to block the action of at least part of the solar radiation energy P _st to reduce the solar radiation correction amount? It is possible to reduce or prevent the occurrence of the error by approximating the measured temperature t of the temperature sensor 12 to the actual temperature t ₀ .

Further, the light-shielding portion 16 may serve to physically protect the temperature sensor 12 or to protect it from an electric shock.

11 to 14, the light-shielding portion 16 may include a front shading plate. The front shading plate 161 and the front shading plate 161 are disposed at a distance from the temperature sensor 12 in front of the temperature sensor 12. The front shading plate 161 and the front shading plate 161 are connected to the boom stand 13, And a bridge 162. 11 and 13, the bridge 162 may extend rearward from the front shielding plate 161 and be connected to (or attached to) the boom frame 13. For example, two bridges 162 may be provided on the upper side of the front shield plate 161, and two bridges 162 may be provided on the lower side. Accordingly, the front shading plate may include four bridges 162. [

11 to 14, the light-shielding portion 16 may include a rear shading plate. The rear shading plate is connected to the boom stand 13 by projecting from each of the upper and lower portions of the rear shield plate 161 and the rear shield plate 161 spaced apart from the temperature sensor 12 at the rear of the temperature sensor 12. [ And a bridge 162. 11 and 13, the bridge 162 may extend forward from the rear shield plate 161 and be connected to (or attached to) the boom frame 13. Further, for example, two bridges 162 may be provided on the upper side of the rear shield plate 161, and two bridges 162 may be provided on the lower side. Accordingly, the rear shading plate may include four bridges 162. [

11, the front light shielding plate 161 and the rear light shielding plate 161 are spaced apart from the temperature sensor 12 in the front-rear direction, A space 163 opened to the outside can be formed. According to the open space 163, air permeability to the inside and the outside of the shielding portion 161 can be ensured and the flow of air into and out of the shielding portion 161 can be smooth.

Further, the front shading plate and the rear shading plate may be a material including plastic. Alternatively, the front shading plate and the rear shading plate may be materials including aluminum or copper. Further, the front shading plate and the rear shading plate may be plate-shaped (thin-shaped) and may be formed in an injection-molded form. Accordingly, the front and rear shield plates can be plate-shaped plastic, plate-like aluminum, or copper plate. In the case where the material constituting the front shading plate and the rear shading plate includes plastic, the bridge 162 is connected (attached) to the boom frame 13 by the adhesive (refer to FIGS. 10 and 13, (Denoted by reference numeral 1621). Further, when the material constituting the front shading plate and the rear shading plate includes aluminum or copper, the bridge 162 can be connected (attached) to the boom rope 13 have. Further, a coating agent may be applied to the surfaces of the front shading plate and the rear shading plate. The coating may be for reflection of solar radiation. In addition, the coating can minimize the transfer of solar radiation (P _st ) by the sun to the temperature sensor (12). For this purpose, the coating may be silver or the like.

In summary, the present radiosonde 1 can be provided with a light shielding portion so that the temperature sensor 12 can block the solar radiation energy P _st absorbed directly by the sun. According to the light shielding portion, The amount of absorption that the temperature sensor 12 directly absorbs the energy P _st can be reduced and the solar radiation correction amount? T of the above-described [Expression 1] and [Expression 2] can be reduced to a very small value, It is possible to remarkably reduce the error compared to the conventional measurement method using the radio-sonde. The radiosonde 1 can smoothly flow the air by making the front light shield plate and the rear light shield plate apart from the temperature sensor 12 at a distance (constant distance) for the air permeability of the temperature sensor 12 . Further, the light-shielding portion 16 may serve to physically protect the temperature sensor 12 or to protect it from an electric shock.

For reference, the correction of the control unit through the solar panel 15 provided adjacent to the temperature sensor 12 described above can be used when the shielding of light by the light-shielding unit 16 is incomplete, that is, When the light is incident on the temperature sensor 12, the error of the measurement temperature that can occur can be corrected. For example, when light incidence by the light-shielding portion 16 can not be intrinsically blocked (for example, light is transmitted to the temperature sensor 12 through the open space 163 for ensuring air permeability into the light-shielding portion 161) The solar panel 15 may be provided so as to have an incident amount of light corresponding to the amount of light incident on the temperature sensor 12 generated as described above, The control unit can correct the error of the measurement temperature.

10 and 11, the radio sonde 1 may include a solar panel 17 provided on an outer surface of the light-shielding portion 16 to generate a voltage with incident light. Also, as described above, the present radiosonde 1 may include a control section which outputs distorted temperature measurement information due to any of the conduction, convection and radiation of heat from the light shield section 16 to the solar panel 17 Based on the voltage measurement information received from the voltage measuring unit.

The temperature sensor 12 can receive heat (either conduction, convection, or radiation) from the light shield 16, and the temperature measured by the temperature sensor 12 by this heat transfer is transmitted to the temperature sensor 12, May be higher than the temperature actually measured at the point where it is located. Accordingly, it may be necessary to perform a temperature correction considering the heat transfer to the temperature sensor 12. [ On the other hand, the control unit of the present radiosonde 1 calculates a correction amount considering the thermal energy transmitted to the temperature sensor 12 by the light incident on the shielding unit 16, A temperature can be corrected. For example, the correction amount can be calculated from the voltage measurement information and a look-up table of the amount of heat energy transmitted from the light shield 16 to the temperature sensor 12. [ Further, the control unit can calculate the corrected temperature t ₀ by subtracting the correction amount from the temperature measured by the temperature sensor 12. [ In addition, for example, the voltage measurement information is generated for a preset amount of time, a maximum value of a voltage amount generated within a predetermined time, a minimum value of a voltage amount generated within a predetermined time, and a preset time And may include an average value of the voltage amounts.

For example, the radiosonde 1 performs the voltage measurement step of the solar panel 15 for a predetermined period of time, calculates a maximum value, a minimum value and an average value of the voltage measurement value to generate voltage measurement information including the voltage measurement value, (Thermal energy) value transmitted to the temperature sensor 12 through a voltage value and a look-up table of the column transmitted to the temperature sensor 12 based on the measurement information, , And the correction amount can be calculated using a look-up table or an equation based on experiments based on the calculated values and the weather data such as temperature, humidity, and wind direction measured in the radiosonde 1 . Then, the actual temperature t ₀ can be calculated.

The thermal energy transmitted to the temperature sensor 12 through the light shielding portion 16 is transmitted through the solar panel 17 mounted on the shielding portion 16 instead of the conventional software- It is possible to have an advantage that the error of the estimated temperature t ₀ is significantly reduced compared with the conventional measuring method.

In this process, the lid sonde 1 can UP-convert UHF (Ultra High Frequency) data collected by the installed sensors to wirelessly transmit temperature, humidity and GPS data, The terrestrial receiver 3 receiving the data can down-convert UHF to extract the measurement data and send it to the data processing device 2. The data processing unit (2) processes and displays the measured data in the form required by the operator of the high-level weather observation system, and transmits the data to the related organizations such as the Korea Meteorological Administration.

The radio sonde 1 also transmits the data measured by the temperature sensor 12, the humidity sensor 11 and the position information sensor 184 mounted on the external float 13 to the radio zone controller 183, UHF, the data of the wireless communication amplified through the frequency up converter 186, the signal amplifier 187, and the communication unit 188 can be transmitted to the terrestrial receiver 3.

18, the main body portion 18 may include an inner case 181. [ The inner case 181 can fix the position of the radio zone controller 183 and the power source-battery 185 in the main body portion 18 thereof.

An outer surface of the outer container 182 may be coated with an insulating coating agent. This may be to prevent electrical shock and physical damage to the outer vessel 182.

In general, radio sonde rises more than 30 km above the ground when it is sunk, and the radiosonde falls to the ground as the balloon bursts by the air pressure car. Accordingly, in general, radio-sonde can not be recovered and treated as garbage in a natural environment. However, the conventional radio-sonde case consists of an inner styrofoam and an outer plastic container, which takes more than 500 years to decompose in a natural state. Nevertheless, the Korea Meteorological Administration and the Air Force regulate the radiosonde two times a day at various points, and the World Meteorological Organization (WMO) regulations are also levied twice a day. In accordance with such domestic and foreign regulations, radio sonde is being recalled twice daily at various places in Korea and can not be recovered because it does not know the drop point after the reconnaissance. As a result, radiosonde can damage nature until it is decomposed in the natural environment (mountains, seas, etc.) into garbage.
