Abstract
Description
本発明は、気球により飛揚されて高層の気象を観測するラジオゾンデに関する。 The present invention relates to a radiosonde that is blown up by a balloon and observes high-rise weather.
高層天気を観測するラジオゾンデは、上層大気の風向、風速、気圧、気温、湿度等を測定し、測定情報を送信機により地上に送信する。 A radiosonde that observes high-rise weather measures the wind direction, wind speed, atmospheric pressure, temperature, humidity, and the like of the upper atmosphere, and transmits measurement information to the ground using a transmitter.
ラジオゾンデは、収納容器と、収納容器内に収納される各種の測定センサーと、測定センサーで測定した測定データの処理を行うデータ処理部と、データ処理部で処理したデータを送信する送信部と、データ処理部,送信部等を構成する電子部品を実装する回路基板、各種の電子部品、センサーに電力を供給する電源電池、送信アンテナ等を有する。また、電源部の改良により使用する乾電池等の本数の削減等により、収納容器の小型化とラジオゾンデの軽量化が実現する（特許文献１）。 The radiosonde includes a storage container, various measurement sensors stored in the storage container, a data processing unit that processes measurement data measured by the measurement sensor, and a transmission unit that transmits data processed by the data processing unit. A circuit board on which electronic components constituting a data processing unit, a transmission unit, and the like are mounted, various electronic components, a power supply battery that supplies power to the sensor, a transmission antenna, and the like. Further, by reducing the number of dry batteries to be used by improving the power supply unit, the storage container can be reduced in size and the radiosonde can be reduced in weight (Patent Document 1).
ラジオゾンデを飛揚する際、周囲に飛揚される他のラジオゾンデとの混信をさけるために、送信周波数を変更する。 When flying a radiosonde, the transmission frequency is changed in order to avoid interference with other radiosondes flying around.
近年、送信周波数の変更は、ラジオゾンデと非接触通信方式で調整装置との間で行われる。従来、非接触の通信方式として、電磁誘導方式が採用されている。電磁誘導方式では、ラジオゾンデに通信用のループアンテナを配置する必要がある。 In recent years, the transmission frequency is changed between the radiosonde and the adjusting device by a non-contact communication method. Conventionally, an electromagnetic induction method has been adopted as a non-contact communication method. In the electromagnetic induction method, it is necessary to arrange a loop antenna for communication on the radiosonde.
ループアンテナは直径が大きいため、収納容器の大型化を招く。また、ループアンテナはラジオゾンデの軽量化を阻害する。 Since the loop antenna has a large diameter, the storage container is increased in size. In addition, the loop antenna hinders the weight reduction of the radiosonde.
また、通信周波数の変更後、各種センサーの測定データが適正に送信できるかのテスト通信が調整装置により行われる。その際、電磁誘導による通信をラジオゾンデと調整装置との間で行うと、高周波の電磁波が、回路基板に実装される各種の回路部に対して電波障害を生じさせる。 Further, after the change of the communication frequency, the adjustment device performs test communication as to whether measurement data of various sensors can be properly transmitted. At that time, when communication by electromagnetic induction is performed between the radiosonde and the adjustment device, high-frequency electromagnetic waves cause radio wave interference to various circuit units mounted on the circuit board.
本発明の目的は、ラジオゾンデに設定する周波数の変更を行うために外部の装置と通信するための通信手段を、ラジオゾンデの軽量化、調整テスト等の安定化に寄与できるものとしたラジオゾンデおよびラジオゾンデの調整装置を提供しようとするものである。 An object of the present invention is to provide a radiosonde in which communication means for communicating with an external device in order to change the frequency set in the radiosonde can contribute to stabilization of the weight of the radiosonde, adjustment tests, and the like.

図１および図２において、ラジオゾンデ１は、発泡スチロール製の収納容器３を有する。ラジオゾンデ１は、図１中、上方に配置された不図示の気球にロープ２（図４参照）を介して吊り下げられる。図１において、互いに直交する３軸をＸ，Ｙ，Ｚ軸とし、上下方向をＺ軸とする。また、Ｘ軸方向を前後方向、Ｙ軸方向を左右方向とする。 1 and 2, the radiosonde 1 has a storage container 3 made of polystyrene foam. The radiosonde 1 is suspended from a balloon (not shown) arranged above in FIG. 1 via a rope 2 (see FIG. 4). In FIG. 1, the three axes orthogonal to each other are defined as the X, Y, and Z axes, and the vertical direction is defined as the Z axis. The X-axis direction is the front-rear direction and the Y-axis direction is the left-right direction.
収納容器３は、Ｚ軸方向に沿って長い略直方体形状に形成される。収納容器３は、Ｚ軸方向の頂部をなす頂面３１と、Ｘ軸方向に沿って対向する前側面３２と後側面３３と、Ｙ軸方向に沿って対向する左右側面３４、３５と、Ｚ軸方向の底部をなす底面３６を有する。また、収納容器３は、後側面３３を有する容器本体３Ａと、前側面３２を有する蓋体３Ｂとにより構成される。容器本体３Ａと蓋体３Ｂとの接合面は、Ｚ−Ｘ平面とし、蓋体３Ｂは容器本体３Ａに対してＺ軸方向に沿って取り外すことができる。 The storage container 3 is formed in a substantially rectangular parallelepiped shape that is long along the Z-axis direction. The storage container 3 includes a top surface 31 that forms a top portion in the Z-axis direction, a front side surface 32 and a rear side surface 33 that face each other along the X-axis direction, left and right side surfaces 34 and 35 that face each other along the Y-axis direction, It has a bottom surface 36 that forms the bottom in the axial direction. The storage container 3 includes a container main body 3A having a rear side surface 33 and a lid body 3B having a front side surface 32. The joint surface between the container body 3A and the lid body 3B is a ZX plane, and the lid body 3B can be removed along the Z-axis direction with respect to the container body 3A.
本実施形態において、頂面３１は後側面３３から前側面３２に向けて下向きに傾斜する片勾配の斜面に形成される。頂面３１は全体的に凸の曲面に形成される。また、前側面３２は、頂面３１の曲面に連設して全体に凸の曲面に形成される。 In the present embodiment, the top surface 31 is formed as a one-sided slope inclined downward from the rear side surface 33 toward the front side surface 32. The top surface 31 is formed as a generally convex curved surface. Further, the front side surface 32 is connected to the curved surface of the top surface 31 and is formed into a convex curved surface as a whole.
収納容器３の前面３Ｃは上下方向において、図４に示すように、頂面３１側を急傾斜の曲面に、前側面３２側を緩傾斜の曲面に形成される。また、収納容器３の前側面３２、後側面３３、左右側面３４、３５の繋ぎ目はそれぞれ曲面に形成されている。さらに、片勾配の傾斜面の頂面３１と前側面３２とにより構成される前面３Ｃは、図５に示すように、Ｙ軸方向の中央が盛り上がり、左右側面３４、３５側を低くした曲面に形成される。 As shown in FIG. 4, the front surface 3 </ b> C of the storage container 3 is formed with a sharply inclined curved surface on the top surface 31 side and a gently inclined curved surface on the front side surface 32 side. Further, the joints of the front side surface 32, the rear side surface 33, and the left and right side surfaces 34, 35 of the storage container 3 are each formed into a curved surface. Further, as shown in FIG. 5, the front surface 3C constituted by the top surface 31 and the front side surface 32 of the one-sided inclined surface is a curved surface in which the center in the Y-axis direction rises and the left and right side surfaces 34, 35 are lowered. It is formed.
ラジオゾンデ１は、収納容器３からセンサーホルダー４と、無線通信用アンテナ６を外部に支出している。 The radiosonde 1 spends the sensor holder 4 and the radio communication antenna 6 from the storage container 3 to the outside.
センサーホルダー４は、ラジオゾンデ１の使用の際に、収納容器３の前面３Ｃ側に配置される。センサーホルダー４は、可撓弾性を有し、非導電性の薄板材により帯状に形成される。センサーホルダー４は、収納容器３内から支出されていて、容器本体３Ａの開口部分に折り畳まれて収容される。蓋体３Ｂを容器本体３Ａから取り外すと、折り畳まれたセンサーホルダー４が現れ、その可撓弾性力に基づく復元力で跳ね上がる。センサーホルダー４が跳ね上がると、容器本体３Ａの前記開口部分が開放される。前記開口部分には、後述する赤外線通信部７１（図７参照）やメイン電源スイッチ等が臨むように配置されている。したがって、センサーホルダー４の跳ね上がりで、赤外線通信部７１（図７参照）の赤外線通信を障害なく行え、またメイン電源スイッチ等の操作を行える。 The sensor holder 4 is disposed on the front surface 3C side of the storage container 3 when the radiosonde 1 is used. The sensor holder 4 has flexible elasticity and is formed in a strip shape from a non-conductive thin plate material. The sensor holder 4 is spent from the inside of the storage container 3, and is folded and accommodated in the opening part of the container main body 3A. When the lid 3B is removed from the container body 3A, the folded sensor holder 4 appears and springs up with a restoring force based on the flexible elastic force. When the sensor holder 4 jumps up, the opening portion of the container body 3A is opened. An infrared communication unit 71 (see FIG. 7), a main power switch, and the like, which will be described later, are disposed in the opening. Therefore, the infrared ray communication of the infrared communication unit 71 (see FIG. 7) can be performed without any obstacle by the bounce of the sensor holder 4, and the main power switch and the like can be operated.
この跳ね上がった状態で蓋体３Ｂを容器本体３Ａに対して被着すると、蓋体３Ｂの上端３Ｂ１と容器本体３Ａの開口端３Ａ１との間に、センサーホルダー４の基端部４１が挟まる。基端部４１の左右両側にはそれぞれ脚部４２が形成される。蓋体３Ｂの前面には、左右一対の脚部４２の下端が係合する係合突起３Ｂ２が突出形成されている。 When the lid 3B is attached to the container main body 3A in the state of being flipped up, the base end portion 41 of the sensor holder 4 is sandwiched between the upper end 3B1 of the lid 3B and the opening end 3A1 of the container main body 3A. Leg portions 42 are respectively formed on the left and right sides of the base end portion 41. On the front surface of the lid 3B, an engagement protrusion 3B2 that engages with the lower ends of the pair of left and right leg portions 42 is formed to protrude.
センサーホルダー４は、基端部４１を弾性変形させながら一対の脚部４２を一対の係合突起部３Ｂ２に係合させることにより、収納容器３の前面３Ｃに支持され、斜め上方に向かって延びる。収納容器３の前面３Ｃに保持されるセンサーホルダー４は、図４に示すように、上方に向かうに従って収納容器３から離れるように延びている。 The sensor holder 4 is supported by the front surface 3C of the storage container 3 and extends obliquely upward by engaging the pair of leg portions 42 with the pair of engaging protrusions 3B2 while elastically deforming the base end portion 41. . As shown in FIG. 4, the sensor holder 4 held on the front surface 3 </ b> C of the storage container 3 extends away from the storage container 3 as it goes upward.
センサーホルダー４は、先端側に設けた温度センサー４３と、基端部側に設けた湿度センサー４４を有する。センサーホルダー４が収納容器３に傾斜支持された状態において、少なくとも温度センサー４３は収納容器３の頂端よりも上方に配置される。湿度センサー４４は、不図示のリード線がセンサーホルダー４を通して収納容器３内の回路７に接続される。 The sensor holder 4 has a temperature sensor 43 provided on the distal end side and a humidity sensor 44 provided on the proximal end side. In a state where the sensor holder 4 is tilted and supported by the storage container 3, at least the temperature sensor 43 is disposed above the top end of the storage container 3. The humidity sensor 44 has a lead wire (not shown) connected to the circuit 7 in the storage container 3 through the sensor holder 4.
センサーホルダー４の温度センサー４３は、センサーホルダー４を構成する可撓弾性を有し、非導電性の薄板材からなり、左右方向に対向配置される左右一対の第１、第２支持片４５、４６と、第１支持片４５と第２支持片４６との間にリード線４７、４８を介して取り付けられるサーミスタ４９を有する。第１支持片４５と第２支持片４６は、基部から上方に二股状に分岐して支出される。各リード線４７、４８はセンサーホルダー４を通して収納容器３内の回路７に接続される。サーミスタ４９は、第１支持片４５と第２支持片４６の先端よりも下方に配置される。 The temperature sensor 43 of the sensor holder 4 includes a pair of left and right first and second support pieces 45 that are flexible and elastic, constituting the sensor holder 4, are made of a non-conductive thin plate material, and are opposed to each other in the left-right direction. 46 and a thermistor 49 attached between the first support piece 45 and the second support piece 46 via lead wires 47 and 48. The first support piece 45 and the second support piece 46 are bifurcated upward from the base and are spent. Each lead wire 47, 48 is connected to the circuit 7 in the storage container 3 through the sensor holder 4. The thermistor 49 is disposed below the tips of the first support piece 45 and the second support piece 46.
温度センサー４３は、第１支持片４５と第２支持片４６の付け根部分が湾曲した凹面に切り欠かれる切欠部５０を有する。そして、切欠部５０の内周縁から第１支持片４５と第２支持片４６の内端縁がそれぞれ連設される。また、第１支持片４５と第２支持片４６の各内端縁が左右方向の外側にそれぞれ開く傾斜した形状とした先細り形状に形成される（以下、放物線切欠き形状と称す）。したがって、第１支持片４５、第２支持片４６に外力が加わっても、第１支持片４５と第２支持片４６の付け根に応力が集中してクラックが入り、破損することが防止される。また、先細り形状とするが、外端縁は長手方向に沿って真っ直ぐな直線状とすることで、強度の低下を防止する。 The temperature sensor 43 has a notch 50 in which the base portions of the first support piece 45 and the second support piece 46 are notched into a curved concave surface. And the inner edge of the 1st support piece 45 and the 2nd support piece 46 is connected from the inner periphery of the notch part 50, respectively. In addition, each inner end edge of the first support piece 45 and the second support piece 46 is formed in a tapered shape having an inclined shape that opens outward in the left-right direction (hereinafter referred to as a parabolic notch shape). Therefore, even if an external force is applied to the first support piece 45 and the second support piece 46, stress is concentrated on the roots of the first support piece 45 and the second support piece 46 to prevent cracking and damage. . Moreover, although it is tapered, the outer end edge is straight and straight along the longitudinal direction, thereby preventing a decrease in strength.
第１支持片４５と第２支持片４６の各内端縁を傾斜縁ではなく平行とした切欠き形状とした場合、第１支持片４５と第２支持片４６を左右方向の外側に開くように外力を加えると、第１支持片４５と第２支持片４６の付け根部分に応力が集中し、クラックが生じ易い。この場合、第１支持片４５と第２支持片４６の長さを長くすれば、よりクラックが発生し易い。これに対し、本実施形態の放物線切欠形状では、第１支持片４５と第２支持片４６の付け根部分と切欠部５０との連接位置が明確ではない。このため、本実施形態の放物線切欠形状では上述したようなクラックの発生が少ない。 When the inner end edges of the first support piece 45 and the second support piece 46 are notched so as to be parallel rather than inclined edges, the first support piece 45 and the second support piece 46 are opened outward in the left-right direction. When an external force is applied to the stress, stress concentrates on the base portions of the first support piece 45 and the second support piece 46, and cracks are likely to occur. In this case, if the lengths of the first support piece 45 and the second support piece 46 are increased, cracks are more likely to occur. On the other hand, in the parabolic notch shape of the present embodiment, the connection position between the base portion of the first support piece 45 and the second support piece 46 and the notch portion 50 is not clear. For this reason, the occurrence of cracks as described above is small in the parabolic notch shape of the present embodiment.
一方、温度センサー４３のサーミスタ４９に対し、長さ方向（第１支持片４５と第２支持片４６の長さ方向）の上下に物体が存在すると、太陽により暖められた当該物体から生じる輻射熱の影響を受ける。本実施形態では、サーミスタ４９の長さ方向上方には輻射熱を発する物体はないが、下方には第１支持片４５と第２支持片４６の基底部５１が存在する。この基底部５１がサーミスタ４９と遠ければ、言い換えれば前記放物線切欠形状を深くすれば輻射熱の影響を低減することができる。すなわち、本実施形態の温度センサー４３は、輻射熱の影響が低減でき、第１支持片４５と第２支持片４６の付け根部分のクラック発生を低減することができる。 On the other hand, when an object exists above and below the thermistor 49 of the temperature sensor 43 in the length direction (the length direction of the first support piece 45 and the second support piece 46), the radiant heat generated from the object heated by the sun to be influenced. In this embodiment, there is no object that emits radiant heat above the thermistor 49 in the longitudinal direction, but the base portions 51 of the first support piece 45 and the second support piece 46 exist below. If the base 51 is far from the thermistor 49, in other words, if the parabolic notch shape is deepened, the influence of radiant heat can be reduced. That is, the temperature sensor 43 of the present embodiment can reduce the influence of radiant heat, and can reduce the occurrence of cracks at the base portions of the first support piece 45 and the second support piece 46.
センサーホルダー４を収納容器３の前面３Ｃに取り付けた使用状態において、収納容器３の片勾配に形成された頂面３１の作用を以下に説明する。 In the state of use in which the sensor holder 4 is attached to the front surface 3C of the storage container 3, the operation of the top surface 31 formed in a single slope of the storage container 3 will be described below.
図４において、不図示の気球からロープ６を介して吊り下げられたラジオゾンデ１は上昇しながら左右方向に搖動する。 In FIG. 4, the radiosonde 1 suspended from a balloon (not shown) via a rope 6 swings in the left-right direction while ascending.
ラジオゾンデ１が右側から左側に搖動すると、頂面３１の上部の気流は、破線Ｆ１で示すように、右から左に向かって流れる。したがって、温度センサー４３には、頂面３１で暖められた空気が流れない。 When the radiosonde 1 swings from the right side to the left side, the air current on the top surface 31 flows from the right to the left as indicated by a broken line F1. Therefore, the air warmed by the top surface 31 does not flow through the temperature sensor 43.
一方、ラジオゾンデ１が左側から右側に搖動すると、頂面３１の上部の搖動気流は、実線Ｆ２で示すように、左側から右側に向かって流れる。搖動気流Ｆ２は、片勾配の頂面３１の斜面に沿って流れる。頂面３１の片勾配は、収納容器３の後側面３３側を頂点とし、前側面３２側を下端とする。したがって、頂面３１で暖められた搖動気流Ｆ２は、センサーホルダー４の基端部に向けて下方に流れ、温度センサー４３には向かわない。特に、温度センサー４３を頂面３１の頂点よりも上方に配置されている。このため、温度センサー４３が搖動気流Ｆ２の流れに入り込むのが避けられる。 On the other hand, when the radiosonde 1 swings from the left side to the right side, the peristaltic airflow at the top of the top surface 31 flows from the left side to the right side as indicated by the solid line F2. The peristaltic airflow F2 flows along the slope of the top surface 31 having a single gradient. The single slope of the top surface 31 has the rear side 33 side as the apex and the front side 32 side as the lower end. Therefore, the peristaltic airflow F <b> 2 heated by the top surface 31 flows downward toward the base end portion of the sensor holder 4 and does not go to the temperature sensor 43. In particular, the temperature sensor 43 is disposed above the apex of the top surface 31. For this reason, it is avoided that the temperature sensor 43 enters the flow of the peristaltic airflow F2.
したがって、ラジオゾンデ１が往復搖動を繰り返しながら上昇して温度計測する際、温度センサー４３で計測した温度計測データは、揺動気流Ｆ２による影響がなくなり、温度センサー４３の実測値が明確に出力される。 Therefore, when the radiosonde 1 rises and repeats reciprocal peristalsis to measure the temperature, the temperature measurement data measured by the temperature sensor 43 is not affected by the oscillating air flow F2, and the measured value of the temperature sensor 43 is clearly output. The
また、温度センサー４３は、センサーホルダー４の輻射熱の影響を受けないので、高精度の温度測定が可能となる。 Further, since the temperature sensor 43 is not affected by the radiant heat of the sensor holder 4, temperature measurement with high accuracy is possible.
次に、収納容器３は、容器本体３Ａ内に、気圧、風向、風速等を測定する各種のセンサー（不図示）を収納する。また、前記各種のセンサーおよび温度センサー４３、湿度センサー４４で測定した測定データの処理を行うデータ処理部（不図示）と、前記データ処理部で処理したデータを送信する通信部（不図示）と、前記データ処理部,前記通信部等を構成する電子部品を実装する回路基板７、各種の電子部品およびセンサーに電力を供給する電源電池である乾電池８、乾電池８の電圧を昇圧するＤＣ−ＤＣコンバータ等で構成される電源部等を有する。前記通信部は、送信周波数を可変とする周波数調整部（不図示）を有する。ラジオゾンデ１を飛揚する際、周囲に飛揚される他のラジオゾンデとの混信をさけるために、送信周波数を変更する。 Next, the storage container 3 stores various sensors (not shown) for measuring the atmospheric pressure, the wind direction, the wind speed, and the like in the container main body 3A. In addition, a data processing unit (not shown) that processes measurement data measured by the various sensors, the temperature sensor 43, and the humidity sensor 44, and a communication unit (not shown) that transmits data processed by the data processing unit , A circuit board 7 on which electronic components constituting the data processing unit, the communication unit, and the like are mounted; a dry battery 8 that is a power supply battery that supplies power to various electronic components and sensors; and a DC-DC that boosts the voltage of the dry battery 8 It has a power supply unit composed of a converter and the like. The communication unit includes a frequency adjustment unit (not shown) that makes the transmission frequency variable. When flying the radiosonde 1, the transmission frequency is changed to avoid interference with other radiosondes flying around.
送信周波数の変更は、図６、図７に示すように、外部の周波数調整等を行う調整装置１００により行われる。調整装置１００は、ラジオゾンデ１の周波数調整部と非接触通信方式で通信を行う。非接触の通信方式として、電磁誘導方式がある。電磁誘導方式では、ラジオゾンデ１に通信用のループアンテナを配置する。ループアンテナは直径が大きいため、収納容器３の大型化を招く。また、ループアンテナはラジオゾンデ１の軽量化を阻害する。通信周波数の変更後、各種センサーの測定データが適正に送信できるかのテスト通信が調整装置１００により行われる。その際、電磁誘導による通信をラジオゾンデ１と調整装置１００との間で行うと、高周波の電磁波が、回路基板７に実装される各種の回路部に対して電波障害を生じさせる。 As shown in FIGS. 6 and 7, the transmission frequency is changed by an adjustment device 100 that performs external frequency adjustment or the like. The adjustment device 100 communicates with the frequency adjustment unit of the radiosonde 1 by a non-contact communication method. As a non-contact communication method, there is an electromagnetic induction method. In the electromagnetic induction method, a loop antenna for communication is arranged on the radiosonde 1. Since the loop antenna has a large diameter, the storage container 3 is increased in size. Further, the loop antenna hinders the weight reduction of the radiosonde 1. After the change of the communication frequency, the adjustment device 100 performs test communication as to whether the measurement data of various sensors can be properly transmitted. At this time, when communication by electromagnetic induction is performed between the radiosonde 1 and the adjustment device 100, high-frequency electromagnetic waves cause radio wave interference in various circuit units mounted on the circuit board 7.
そこで、本実施形態において、ラジオゾンデ１と調整装置１００との非接触通信方式は、赤外線通信を用いている。赤外線通信においては、ループアンテナ等のアンテナは不要であるため、収納容器の小型軽量化が図れる。 Therefore, in this embodiment, the non-contact communication method between the radiosonde 1 and the adjustment device 100 uses infrared communication. In infrared communication, since an antenna such as a loop antenna is not necessary, the storage container can be reduced in size and weight.
回路基板７は、実装面を容器本体３Ａの開口側に向けて配置される。回路基板７の実装面には、赤外線通信用の赤外線通信部７１が実装される。赤外線通信部７１は、蓋体３Ｂを取り外すと、容器本体３Ａの開口に露出する。赤外線通信部７１は、赤外発光素子と、赤外光受光素子とを有する。 The circuit board 7 is arranged with the mounting surface facing the opening side of the container body 3A. An infrared communication unit 71 for infrared communication is mounted on the mounting surface of the circuit board 7. When the lid 3B is removed, the infrared communication unit 71 is exposed to the opening of the container body 3A. The infrared communication unit 71 includes an infrared light emitting element and an infrared light receiving element.

It is partitioned by a rear chamber 105 whose temperature is adjusted.
前室１０４の前面には傾斜した前壁部１０６が設けられる。ラジオゾンデ１は、蓋体３Ｂを取り外した状態で、容器本体３Ａの開口側を前壁部１０６に載置する。この載置状態で、前壁部１０６に形成した開口部１０７にラジオゾンデ１の赤外線通信部７１が望む。 An inclined front wall portion 106 is provided in front of the front chamber 104. The radiosonde 1 places the opening side of the container main body 3A on the front wall portion 106 with the lid 3B removed. In this mounted state, the infrared communication portion 71 of the radiosonde 1 is desired in the opening 107 formed in the front wall portion 106.
前室１０４内には、前壁部１０６の開口部１０７に面して赤外線通信部１０８が配置される。赤外線通信部１０８はラジオゾンデ１の赤外線通信部７１に対向し、赤外線通信部７１との間で通信を行う。 An infrared communication unit 108 is disposed in the front chamber 104 so as to face the opening 107 of the front wall 106. The infrared communication unit 108 faces the infrared communication unit 71 of the radiosonde 1 and communicates with the infrared communication unit 71.
後室１０５内には、容器本体３Ａから延びるセンサーホルダー４が挿入される。後室１０５と、下区室１０１Ｂとの間に、送風機１０９が配置され、下区室１０１Ｂ内の空気を後室１０５内に送風し、後室１０５内の温度を一定にする。 In the rear chamber 105, the sensor holder 4 extending from the container body 3A is inserted. A blower 109 is arranged between the rear chamber 105 and the lower compartment 101B, and the air in the lower compartment 101B is blown into the rear chamber 105 to keep the temperature in the rear chamber 105 constant.
調整装置１００は、例えばパーソナルコンピュータ（不図示）等の調整指示部と接続され、周波数の変更をラジオゾンデ１の周波数調整部に指示する。ラジオゾンデ１は、変更された周波数により、各種センサーで測定したテストデータが通信アンテナ６を介して送信される。温度センサー４３は、後室１０５内の温度を測定する。 The adjustment device 100 is connected to an adjustment instruction unit such as a personal computer (not shown), for example, and instructs the frequency adjustment unit of the radiosonde 1 to change the frequency.
