The breed of chickens raised in the poultry house 100 is, for example, a broiler (more specifically, chunky, cobb, or arbor aca, etc.), but may be other breeds, such as so-called local chickens. A feeder 60, a water dispenser (not shown) and the like are arranged in the poultry house 100.
　送風制御システム１０は、鶏舎１００内の環境（例えば、室温など）に基づいて送風装置５０を制御するのではなく、鶏舎１００内の鶏の体感温度に基づいて送風装置５０を制御する。ここで、鶏の体感温度を直接計測することは困難であることから、送風制御システム１０は、鶏の体表面温度を鶏の推定体感温度とみなし、鶏の体表面温度に基づいて送風装置５０を制御する。図１及び図２に示されるように、送風制御システム１０は、制御装置２０と、温度計測装置３０と、撮影装置４０と、送風装置５０とを備える。以下、各装置について詳細に説明する。 The blower control system 10 does not control the blower device 50 based on the environment (for example, room temperature) in the poultry house 100, but controls the blower device 50 based on the sensible temperature of the chicken in the poultry house 100. Here, since it is difficult to directly measure the sensible temperature of the chicken, the blower control system 10 regards the body surface temperature of the chicken as the estimated sensible temperature of the chicken, and the blower device 50 is based on the body surface temperature of the chicken. To control. As shown in FIGS. 1 and 2, the ventilation control system 10 includes a control device 20, a temperature measuring device 30, a photographing device 40, and a blowing device 50. Hereinafter, each device will be described in detail.
　［制御装置］
　制御装置２０は、送風装置５０を制御する。制御装置２０は、情報処理部２１と、通信部２２と、記憶部２３とを備える。 [Control device]
The control device 20 controls the blower device 50. The control device 20 includes an information processing unit 21, a communication unit 22, and a storage unit 23.
　情報処理部２１は、送風装置５０を制御するための情報処理を行う。情報処理部２１は、具体的には、制御信号を通信部２２に送風装置５０へ送信させることにより、送風装置５０のオン及びオフ、並びに、風速（言い換えれば、風量）を制御する。情報処理部２１は、例えば、マイクロコンピュータによって実現されるが、プロセッサによって実現されてもよい。情報処理部２１は、取得部２４と、制御部２５とを有する。 The information processing unit 21 performs information processing for controlling the blower device 50. Specifically, the information processing unit 21 controls the on / off of the blower device 50 and the wind speed (in other words, the air volume) by causing the communication unit 22 to transmit the control signal to the blower device 50. The information processing unit 21 is realized by, for example, a microcomputer, but may be realized by a processor. The information processing unit 21 has an acquisition unit 24 and a control unit 25.
　通信部２２は、制御装置２０が温度計測装置３０、撮影装置４０、及び、送風装置５０と局所通信ネットワークを介して通信を行うための通信モジュール（通信回路）である。通信部２２によって行われる通信は、有線通信であってもよいし無線通信であってもよい。通信部２２は、温度計測装置３０、撮影装置４０、及び、送風装置５０の各装置と通信可能であればよい。また、通信部２２の通信方式（通信規格、通信プロトコル）は、特に限定されない。通信部２２には、各装置と通信を行うための複数種類の通信モジュールが含まれてもよい。また、通信部２２と、各装置との間には、ルータなどの中継装置が介在してもよい。 The communication unit 22 is a communication module (communication circuit) for the control device 20 to communicate with the temperature measuring device 30, the photographing device 40, and the blower device 50 via the local communication network. The communication performed by the communication unit 22 may be wired communication or wireless communication. The communication unit 22 may be capable of communicating with each of the temperature measuring device 30, the photographing device 40, and the blower device 50. The communication method (communication standard, communication protocol) of the communication unit 22 is not particularly limited. The communication unit 22 may include a plurality of types of communication modules for communicating with each device. Further, a relay device such as a router may be interposed between the communication unit 22 and each device.
　記憶部２３は、情報処理部２１によって実行される制御プログラムなどが記憶される記憶装置である。記憶部２３は、例えば、半導体メモリによって実現される。 The storage unit 23 is a storage device that stores a control program or the like executed by the information processing unit 21. The storage unit 23 is realized by, for example, a semiconductor memory.
　［温度計測装置］
　温度計測装置３０は、鶏舎１００内の鶏の体感温度（言い換えれば、体表面温度）を示す情報を計測する。鶏の体感温度は、鶏の生体情報の一例である。温度計測装置３０は、具体的には、複数の赤外線検出素子によって構成される熱画像センサであり、熱画像を撮影する。温度計測装置３０は、その他の温度センサ（例えば、非接触型の温度センサなど）であってもよい。 [Temperature measuring device]
The temperature measuring device 30 measures information indicating the sensible temperature (in other words, the body surface temperature) of the chicken in the poultry house 100. The sensible temperature of a chicken is an example of biological information of a chicken. Specifically, the temperature measuring device 30 is a thermal image sensor composed of a plurality of infrared detection elements, and captures a thermal image. The temperature measuring device 30 may be another temperature sensor (for example, a non-contact type temperature sensor).
　温度計測装置３０は、例えば、給餌器６０の上方に設置される。図３は、温度計測装置３０の設置例を示す図である。図３に示されるように温度計測装置３０が給餌器６０の上方の給餌器６０と離れた位置に設置されれば、温度計測装置３０が鶏につつかれて故障してしまうことが抑制される。また、温度計測装置３０と鶏との位置関係がほぼ一定に保たれることで温度のばらつき要因が減少し、高精度な熱画像が得られる。 The temperature measuring device 30 is installed above the feeder 60, for example. FIG. 3 is a diagram showing an installation example of the temperature measuring device 30. If the temperature measuring device 30 is installed at a position away from the feeder 60 above the feeder 60 as shown in FIG. 3, it is possible to prevent the temperature measuring device 30 from being poked by the chicken and failing. .. Further, by keeping the positional relationship between the temperature measuring device 30 and the chicken substantially constant, the factors of temperature variation are reduced, and a highly accurate thermal image can be obtained.
　また、温度計測装置３０が鶏の頭の位置よりも上方に設置されれば、餌を摂取中の鶏は下を向くため、くちばしなどの頭部と体表面温度が異なる部位が撮影対象に含まれにくくなる。よって、温度計測装置３０は、鶏の頭部の体表面温度を高精度に計測することができる。 Further, if the temperature measuring device 30 is installed above the position of the chicken's head, the chicken ingesting food faces downward, so that a part such as a beak whose body surface temperature is different from that of the head is included in the imaging target. It becomes difficult to get rid of. Therefore, the temperature measuring device 30 can measure the body surface temperature of the chicken head with high accuracy.
　また、図４は、図３のように設置された温度計測装置によって撮影される熱画像の一例を示す図である。図４に示されるように給餌器６０を示す円状の領域Ａ１の周囲の領域Ａ２は領域Ａ１よりも温度が高く、領域Ａ２には鶏の頭部が位置する可能性がある。そこで、温度計測装置３０の設置時に熱画像のうち鶏の頭部が位置する可能性がある領域Ａ２を設定情報として記憶部２３に記憶しておけば、取得部２４は、熱画像に基づいて鶏の頭部の体表面温度を取得することができる。 Further, FIG. 4 is a diagram showing an example of a thermal image taken by a temperature measuring device installed as shown in FIG. As shown in FIG. 4, the area A2 around the circular area A1 showing the feeder 60 has a higher temperature than the area A1, and the chicken head may be located in the area A2. Therefore, if the area A2 of the thermal image in which the chicken head may be located is stored in the storage unit 23 as setting information when the temperature measuring device 30 is installed, the acquisition unit 24 will be based on the thermal image. The body surface temperature of the chicken head can be obtained.
　なお、温度計測装置３０が給餌器６０の上方に設置されることは必須ではなく、温度計測装置３０は、給餌器６０自体の上部に設置されてもよいし、給水器（図示せず）の上方に設置されてもよいし、給水器自体に設置されてもよい。温度計測装置３０は、給餌器６０及び給水器と無関係な位置に設置されてもよい。温度計測装置３０は、鶏の体表面温度を計測できる位置に設置されればよい。 It is not essential that the temperature measuring device 30 is installed above the feeder 60, and the temperature measuring device 30 may be installed above the feeder 60 itself, or the water dispenser (not shown). It may be installed above or on the water dispenser itself. The temperature measuring device 30 may be installed at a position unrelated to the feeder 60 and the water dispenser. The temperature measuring device 30 may be installed at a position where the body surface temperature of the chicken can be measured.
　［撮影装置］
　撮影装置４０は、鶏舎１００の天井または壁に取り付けられ、鶏舎１００内を俯瞰した画像を撮像する。撮影装置４０は、イメージセンサ、及び、イメージセンサに光を導く光学系（レンズ等）などによって実現される。イメージセンサは、具体的には、ＣＭＯＳ（Ｃｏｍｐｌｅｍｅｎｔａｒｙ　Ｍｅｔａｌ　Ｏｘｉｄｅ　Ｓｅｍｉｃｏｎｄｕｃｔｏｒ）センサまたはＣＣＤ（Ｃｈａｒｇｅ　Ｃｏｕｐｌｅｄ　Ｄｅｖｉｃｅ）センサなどである。 [Shooting device]
The photographing device 40 is attached to the ceiling or wall of the poultry house 100 and captures an image of the inside of the poultry house 100 from a bird's-eye view. The photographing device 40 is realized by an image sensor, an optical system (lens or the like) that guides light to the image sensor, and the like. Specifically, the image sensor is a CMOS (Complementary Metal Oxide Semiconductor) sensor, a CCD (Charge Coupled Device) sensor, or the like.
　［送風装置］
　送風装置５０は、通信部２２から送信される制御信号に基づいて、鶏舎１００内の空調または換気を行う。送風装置５０は、例えば、鶏舎１００の壁に埋め込み設置される、畜産用の大型換気扇であるが、または、全体が鶏舎１００内に設置される大型扇風機であってもよい。送風装置５０は、送風機能に加えて、温度調整機能を有する空気調和機（エアーコンディショナ）などであってもよい。 [Blower]
The blower 50 performs air conditioning or ventilation in the poultry house 100 based on the control signal transmitted from the communication unit 22. The blower 50 is, for example, a large ventilation fan for livestock that is embedded in the wall of the poultry house 100, or may be a large fan that is entirely installed in the poultry house 100. The blower device 50 may be an air conditioner (air conditioner) or the like having a temperature adjusting function in addition to the blower function.
　［発明者らの知見］
　発明者らの知見によれば、鶏舎１００内の室温がほぼ同じ２つのケースにおいて、鶏舎１００内の鶏の体感温度（体表面温度）には大きく差が生じる場合がある。図５及び図６は、送風装置５０の風速の大小と、そのときの室温（環境温度）及び鶏の体表面温度との関係を示す図である。図５は、１日における、室温の変化、及び、１羽の鶏の体表面温度の変化を示す図であり、図６は、１日における室温の平均値の複数日にわたる推移、及び、１日における１羽の鶏の体表面温度の平均値の複数日にわたる推移を示す図である。図５及び図６に示されるグラフは、発明者らによって実測されたデータに基づいている。 [Inventors' findings]
According to the findings of the inventors, there may be a large difference in the sensible temperature (body surface temperature) of the chickens in the poultry house 100 in the two cases where the room temperature in the poultry house 100 is substantially the same. 5 and 6 are diagrams showing the relationship between the magnitude of the wind speed of the blower 50, the room temperature (environmental temperature) at that time, and the body surface temperature of the chicken. FIG. 5 is a diagram showing changes in room temperature and changes in body surface temperature of one chicken in one day, and FIG. 6 shows changes in the average value of room temperature in one day over a plurality of days and 1 It is a figure which shows the transition of the average value of the body surface temperature of one chicken in a day over a plurality of days. The graphs shown in FIGS. 5 and 6 are based on data measured by the inventors.
　図５及び図６に示されるように、送風装置５０の風速の大小により室温がそれほど変化していない場合であっても、鶏の体表面温度が大きく異なる場合がある。一般的な技術として、鶏舎１００内の室温に基づいて送風装置５０を制御するシステムが考えられるが、このようなシステムは、鶏の体表面温度（つまり、体感温度）を考慮して送風装置５０を制御することが難しいといえる。 As shown in FIGS. 5 and 6, even when the room temperature does not change so much depending on the magnitude of the wind speed of the blower 50, the body surface temperature of the chicken may differ significantly. As a general technique, a system that controls the blower 50 based on the room temperature in the poultry house 100 can be considered, but such a system considers the body surface temperature (that is, the sensible temperature) of the chicken and blows the blower 50. It can be said that it is difficult to control.
　［動作例１］
　そこで、送風制御システム１０は、鶏の体表面温度に基づいて送風装置５０を制御する。図７は、このような送風制御システム１０の動作例１のフローチャートである。 [Operation example 1]
Therefore, the blower control system 10 controls the blower device 50 based on the body surface temperature of the chicken. FIG. 7 is a flowchart of an operation example 1 of such a ventilation control system 10.
　まず、温度計測装置３０は、鶏の頭部が映る熱画像を撮影する（Ｓ１１）。上述のように、温度計測装置３０は、鶏舎１００内に設置された給餌器６０の上方に位置し（上記図３参照）、餌をついばむ鶏の頭部を被写体とする熱画像を撮影する。 First, the temperature measuring device 30 captures a thermal image showing the head of the chicken (S11). As described above, the temperature measuring device 30 is located above the feeder 60 installed in the poultry house 100 (see FIG. 3 above), and takes a thermal image of the head of the chicken pecking the food as a subject.
　次に、取得部２４は、温度計測装置３０によって撮影された熱画像から鶏の体表面温度を取得する（Ｓ１２）。取得部２４は、撮影された熱画像のうち鶏の頭部が位置する可能性がある領域Ａ２（上記図４参照）を示す設定情報を参照し、例えば、領域Ａ２の中で温度の高い位置の上位ｎ個（ｎは自然数。例えばｎ＝３。）の平均値を鶏の体表面温度として取得する。また、取得部２４は、熱画像に鶏の頭部が映っていないときの温度を取得してしまわないように、領域Ａ２の平均温度が所定値以上であるときに領域Ａ２の中で温度の高い位置の上位ｎ個の平均値を鶏の体表面温度として取得してもよい。 Next, the acquisition unit 24 acquires the chicken body surface temperature from the thermal image taken by the temperature measuring device 30 (S12). The acquisition unit 24 refers to the setting information indicating the region A2 (see FIG. 4 above) in which the chicken head may be located in the captured thermal image, and for example, the position where the temperature is high in the region A2. The average value of the top n (n is a natural number, for example, n = 3) is obtained as the body surface temperature of the chicken. Further, the acquisition unit 24 determines the temperature in the region A2 when the average temperature of the region A2 is equal to or higher than a predetermined value so as not to acquire the temperature when the chicken head is not shown in the thermal image. The average value of the top n high positions may be obtained as the body surface temperature of the chicken.
　なお、取得部２４は、温度の変化しにくい給餌器６０の温度（つまり、図４の領域Ａ１の温度）を基準として校正された体表面温度を取得してもよい。これにより、体表面温度の取得精度が向上される。また、上記図３に示されるように、壁などに黒体７０が設置され、熱画像の端部などにこのような黒体７０が映っている場合（つまり、温度計測装置３０の撮影範囲内に黒体が位置する場合）、取得部２４は、給餌器６０よりもさらに温度の変化しにくい黒体７０の温度を基準として校正された体表面温度を取得してもよい。これにより、体表面温度の取得精度がさらに向上される。なお、黒体７０は、黒色のテープなどによって実現される。熱画像内の黒体の位置はあらかじめ記憶部２３に設定情報として記憶される。 The acquisition unit 24 may acquire the body surface temperature calibrated based on the temperature of the feeder 60 (that is, the temperature of the region A1 in FIG. 4) in which the temperature does not change easily. As a result, the accuracy of acquiring the body surface temperature is improved. Further, as shown in FIG. 3, when a blackbody 70 is installed on a wall or the like and such a blackbody 70 is reflected on an edge of a thermal image (that is, within the shooting range of the temperature measuring device 30). When the blackbody is located in the blackbody), the acquisition unit 24 may acquire the body surface temperature calibrated based on the temperature of the blackbody 70, which is less likely to change in temperature than the feeder 60. As a result, the accuracy of acquiring the body surface temperature is further improved. The black body 70 is realized by a black tape or the like. The position of the blackbody in the thermal image is stored in advance in the storage unit 23 as setting information.
　次に、制御部２５は、取得された鶏の体表面温度に基づいて通信部２２に送風装置５０へ制御信号を送信させることにより、送風装置５０を制御する（Ｓ１３）。例えば、制御部２５は、体表面温度が高いほど送風装置５０の風速（言い換えれば、風量）を増加させる。このときの風速は、何段階で変更されてもよい。また、制御部２５は、体表面温度が所定値未満であるときには送風装置５０をオフし、体表面温度が所定値以上であるときには送風装置５０をオンする制御を行ってもよい。 Next, the control unit 25 controls the blower device 50 by causing the communication unit 22 to transmit a control signal to the blower device 50 based on the acquired chicken body surface temperature (S13). For example, the control unit 25 increases the wind speed (in other words, the air volume) of the blower 50 as the body surface temperature increases. The wind speed at this time may be changed in any number of steps. Further, the control unit 25 may control to turn off the blower device 50 when the body surface temperature is less than a predetermined value and turn on the blower device 50 when the body surface temperature is more than a predetermined value.
　また、制御部２５は、送風装置５０が温度調整機能を有している場合には、取得された鶏の体表面温度に基づいて通信部２２に送風装置５０へ制御信号を送信させることにより、送風装置５０の設定温度を制御してもよい。例えば、制御部２５は、体表面温度が高いほど送風装置５０の設定温度を低くする。 Further, when the blower device 50 has a temperature adjusting function, the control unit 25 causes the communication unit 22 to transmit a control signal to the blower device 50 based on the acquired chicken body surface temperature. The set temperature of the blower 50 may be controlled. For example, the control unit 25 lowers the set temperature of the blower 50 as the body surface temperature rises.
　以上説明したように、送風制御システム１０は、室温ではなく鶏の体表面温度に基づいて送風装置５０を制御する。このため、送風制御システム１０は、鶏舎１００内の環境を鶏にとって快適な環境に近づけることができ、この結果、鶏の育成が促進される。 As described above, the blower control system 10 controls the blower device 50 based on the body surface temperature of the chicken, not the room temperature. Therefore, the ventilation control system 10 can bring the environment in the poultry house 100 closer to a comfortable environment for the chickens, and as a result, the breeding of the chickens is promoted.
　なお、取得部２４は、鶏の頭部以外の部位（例えば、胸部）の体表面温度を取得してもよいが、鶏の頭部の体表面温度は、以下の理由により、鶏の体感温度に近い温度であると考えられる。鶏の頭部は他の部位に比べて羽毛が少ないため、鶏の頭部の体表面温度は、他の部位の体表面温度よりも鶏の体温に近い、つまり、鶏の体感温度に近いと考えられる。また、体感温度は脳によって認識されるため、脳が含まれる頭部の体表面温度は、鶏の体感温度に近いと考えられる。 The acquisition unit 24 may acquire the body surface temperature of a portion other than the chicken head (for example, the chest), but the body surface temperature of the chicken head is the sensible temperature of the chicken for the following reasons. It is considered that the temperature is close to. Since the chicken head has less feathers than other parts, the body surface temperature of the chicken head is closer to the chicken body temperature than the body surface temperature of other parts, that is, it is closer to the chicken's sensible temperature. Conceivable. Moreover, since the sensible temperature is recognized by the brain, the body surface temperature of the head including the brain is considered to be close to the sensible temperature of the chicken.
　なお、鶏の頭部のうち、体表面温度の計測に適した部位としては、鶏冠、鶏の目、または、鶏の目の周辺部が例示される。取得部２４は、熱画像のうちこれらの部位があると推定される位置における温度を鶏の体表面温度として取得してもよい。また、撮影装置４０が撮像する画像と、温度計測装置３０が撮影する熱画像との対応がとれる場合には、取得部２４は、撮影装置４０が撮像した画像内の鶏の鶏冠、鶏の目、または、鶏の目の周辺部の位置をパターンマッチング等の手法によって特定することにより、当該画像に対応する熱画像内の鶏の鶏冠、鶏の目、または、鶏の目の周辺部の位置を特定し、特定した位置の温度を鶏の体表面温度として取得することもできる。 Of the chicken head, examples of parts suitable for measuring body surface temperature include the comb, chicken eyes, or the periphery of chicken eyes. The acquisition unit 24 may acquire the temperature at the position where these parts are presumed to be in the thermal image as the body surface temperature of the chicken. When the image captured by the photographing device 40 and the thermal image captured by the temperature measuring device 30 can be matched, the acquisition unit 24 may use the chicken crown and chicken eyes in the image captured by the photographing device 40. Or, by specifying the position of the peripheral part of the chicken eye by a method such as pattern matching, the position of the chicken crown, the chicken eye, or the peripheral part of the chicken eye in the thermal image corresponding to the image. It is also possible to specify and obtain the temperature at the specified position as the body surface temperature of the chicken.
　［動作例２］
　そこで、送風制御システム１０は、鶏の体表面温度（言い換えれば、体感温度）以外の他の生体情報に基づいて送風装置５０を制御してもよい。図８は、このような送風制御システム１０の動作例２のフローチャートである。 [Operation example 2]
Therefore, the blower control system 10 may control the blower device 50 based on biological information other than the chicken body surface temperature (in other words, the sensible temperature). FIG. 8 is a flowchart of an operation example 2 of such a ventilation control system 10.
　まず、撮影装置４０は、鶏が映る画像を撮影する（Ｓ２１）。次に、取得部２４は、撮影装置４０によって撮影された画像から鶏のパンティングの状態を生体情報として取得する（Ｓ２２）。パンティングとは、鶏が体温を下げる目的で口を開けて行う呼吸のことである。取得部２４は、例えば、撮影装置４０によって撮影された画像を画像処理することにより鶏のパンティングの状態（パンティングの頻度など）を取得する。取得部２４は、鶏のパンティング状態を学習した学習モデルであって、画像を入力してパンティングの状態を出力する学習モデルに基づいて、パンティングの状態を取得してもよい。 First, the photographing device 40 photographs an image in which a chicken is reflected (S21). Next, the acquisition unit 24 acquires the chicken punting state as biological information from the image captured by the imaging device 40 (S22). Punting is the breathing that a chicken takes with its mouth open to lower its body temperature. The acquisition unit 24 acquires the punting state (frequency of punting, etc.) of the chicken by performing image processing on the image captured by the photographing device 40, for example. The acquisition unit 24 is a learning model that learns the punting state of the chicken, and may acquire the punting state based on the learning model that inputs an image and outputs the punting state.
　次に、制御部２５は、取得された鶏のパンティングの状態に基づいて通信部２２に送風装置５０へ制御信号を送信させることにより、送風装置５０を制御する（Ｓ２３）。例えば、制御部２５は、パンティングの頻度が高いほど送風装置５０の風速を増加させる。このときの風速は、何段階で変更されてもよい。また、制御部２５は、パンティングの頻度が所定値未満であるときには送風装置５０をオフし、パンティングの頻度が所定値以上であるときには送風装置５０をオンする制御を行ってもよい。 Next, the control unit 25 controls the blower device 50 by causing the communication unit 22 to transmit a control signal to the blower device 50 based on the acquired chicken punting state (S23). For example, the control unit 25 increases the wind speed of the blower 50 as the frequency of punting increases. The wind speed at this time may be changed in any number of steps. Further, the control unit 25 may control to turn off the blower device 50 when the frequency of punting is less than a predetermined value and turn on the blower device 50 when the frequency of punting is more than a predetermined value.
　また、制御部２５は、送風装置５０が温度調整機能を有している場合には、取得された鶏のパンティングの状態に基づいて通信部２２に送風装置５０へ制御信号を送信させることにより、送風装置５０の設定温度を制御してもよい。例えば、制御部２５は、パンティングの頻度が高いほど送風装置５０の設定温度を低くする。 Further, when the blower device 50 has a temperature adjusting function, the control unit 25 causes the communication unit 22 to transmit a control signal to the blower device 50 based on the acquired chicken punting state. , The set temperature of the blower 50 may be controlled. For example, the control unit 25 lowers the set temperature of the blower 50 as the frequency of punting increases.
　以上説明したように、送風制御システム１０は、室温ではなく鶏のパンティングの状態に基づいて送風装置５０を制御する。このため、送風制御システム１０は、鶏舎１００内の環境を鶏にとって快適な環境に近づけることができ、この結果、鶏の育成が促進される。 As described above, the blower control system 10 controls the blower device 50 based on the punting state of the chicken, not on the room temperature. Therefore, the ventilation control system 10 can bring the environment in the poultry house 100 closer to a comfortable environment for the chickens, and as a result, the breeding of the chickens is promoted.
　なお、鶏は、パンティング以外に羽をばたつかせることで体温を下げる習性を有する。そこで、上記パンティングの状態に代えて、または、上記パンティングの状態に加えて、このような羽のばたつかせ状態が生体情報として使用されてもよい。 In addition to punting, chickens have a habit of lowering their body temperature by flapping their wings. Therefore, instead of the above-mentioned punting state, or in addition to the above-mentioned punting state, such a feather flapping state may be used as biological information.
　［効果等］
　以上説明したように、送風制御システム１０は、鶏舎１００内の鶏の生体情報を取得する取得部２４と、取得された生体情報に基づいて鶏舎１００に設置された送風装置５０を制御する制御部２５とを備える。 [Effects, etc.]
As described above, the ventilation control system 10 is a control unit that controls an acquisition unit 24 that acquires biological information of chickens in the poultry house 100 and a ventilation device 50 installed in the poultry house 100 based on the acquired biological information. 25 and.
　このような送風制御システム１０は、鶏の生体情報に基づいて送風装置５０を制御することにより、鶏の周囲の環境情報に基づいて送風装置５０を制御する場合よりも鶏舎１００内の環境を鶏にとって快適な環境に近づけることができる。この結果、鶏の育成が促進される。 By controlling the blower device 50 based on the biological information of the chicken, such a blower control system 10 controls the environment inside the poultry house 100 as compared with the case where the blower device 50 is controlled based on the environmental information around the chicken. You can get closer to a comfortable environment for you. As a result, chicken breeding is promoted.
　また、例えば、取得部２４は、生体情報として鶏の体感温度を取得し、制御部２５は、取得された鶏の体感温度に基づいて送風装置５０を制御する。 Further, for example, the acquisition unit 24 acquires the chicken's sensible temperature as biological information, and the control unit 25 controls the blower 50 based on the acquired chicken's sensible temperature.
