Description

[Technical Field]

[0001] The present disclosure generally relates to an environmental control system, a livestock barn, a sensible temperature calculation method, and a program, and more particularly to an environmental control system, a livestock barn, a sensible temperature calculation method, and a program that include a sensible temperature calculation system used in a space where livestock are present. [Background technology]

[0002] Patent Document 1 describes an environmental control system that controls the environment inside and outside an open-type chicken house (see, for example, Patent Document 1).

[0003] The poultry house in which the environmental control system described in Patent Document 1 is used is equipped with temperature and humidity sensors, wind speed sensors, and gas sensors for ammonia, etc. The environmental control system inputs each detected value into a control computer via control means, compares it with a control program that has been input in advance, and outputs the results of the collation and analysis from a control terminal in the poultry house via the control means, thereby comprehensively controlling each control device.

[0004] Patent Document 1 describes items that are major factors in egg productivity, such as perceived temperature, perceived humidity, perceived illuminance, perceived gas concentration, perceived wind speed, etc. Furthermore, Patent Document 1 describes that in order to meet all of the above items, detection can be performed by various sensors, and control can be carried out by a control computer having a control program.

[0005] However, the conventional environmental control system described in Patent Document 1 has a problem in that the accuracy of the spatial environment is low because it indicates the temperature that poultry in the space feel. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 11-225599 Summary of the Invention [Problem to be solved by the invention]

[0007] The present disclosure has been made in consideration of the above points, and the purpose of the present disclosure is to provide an environmental control system, livestock barn, sensible temperature calculation method, and program that can control the environment of a space so that the actual sensible temperature of livestock throughout the space is a temperature suitable for the livestock. [Means for solving the problem]

[0008] An environmental control system according to one embodiment of the present disclosure includes a sensible temperature calculation system, a control system, an equipment control unit, a tracking calculation unit, and an anomaly detection unit. The sensible temperature calculation system includes a first calculation unit and a second calculation unit. The first calculation unit calculates an environmental distribution of a space in a livestock barn, a building having an air intake and an exhaust vent, using environmental information representing at least one of temperature, humidity, and wind speed at two representative points: an upwind representative point near the air intake and a downwind representative point near the exhaust vent, as information representing the environment of the space in which the livestock reside. The second calculation unit calculates the sensible temperature distribution of the livestock by obtaining, from an imaging device or an infrared monitoring device, a three-dimensional distribution including the environmental distribution calculated by the first calculation unit, biological detection information representing the presence of the livestock, and the heights of the livestock. The control system is used in conjunction with ventilation equipment that ventilates the interior space of the building and controls the wind speed of air supplied through the air intake of the building, passed through the interior space, and exhausted to the outside of the building through the exhaust vent of the building. The equipment control unit controls environmental equipment for controlling the environment of the space. The tracking calculation unit tracks the positions of the livestock using position information representing the positions of the livestock. The abnormality detection unit detects livestock present in a space with an abnormal environment.

[0009] The control system includes at least one baffle member. The baffle member is provided in the interior space between the air inlet and the exhaust outlet, and is suspended from the ceiling of the building so as to leave a space between its lower end and the floor of the building. The height of the lower end of the baffle member is higher than the height of the upper end of the air inlet and lower than the height of the upper end of the exhaust outlet. The equipment control unit uses the living organism detection information to control the environmental equipment so as to control the environment of the area where the livestock are actually present. The equipment control unit controls the environmental equipment so as to control the environment of the location of the livestock tracked by the tracking calculation unit. At least one of the first calculation unit and the second calculation unit performs calculations using a trained classifier that has undergone machine learning.

[0010] A sensible temperature calculation method according to one aspect of the present disclosure includes a first calculation step, a second calculation step, a control step, an equipment control step, a tracking calculation step, and an abnormality detection step. In the first calculation step, a spatial environmental distribution is calculated for a livestock barn, a building having an air intake and an exhaust vent, using environmental information representing at least one of temperature, humidity, and wind speed at two representative points: an upwind representative point near the air intake vent and a downwind representative point near the exhaust vent, as information representing the spatial environment of the livestock. In the second calculation step, a three-dimensional distribution including the environmental distribution calculated in the first calculation step, living body detection information representing the presence of the livestock, and the height of the livestock is obtained from an imaging device or an infrared monitoring device to calculate the sensible temperature distribution of the livestock. In the control step, in an interior space of the building ventilated by ventilation equipment, the wind speed of air supplied through the air intake of the building, passed through the interior space, and exhausted to the outside of the building from the exhaust vent of the building is controlled. In the equipment control step, environmental equipment for controlling the spatial environment is controlled. In the tracking calculation step, the positions of the livestock are tracked using position information representing the positions of the livestock. In the abnormality detection step, livestock present in a space with an abnormal environment are detected.

[0011] In the control step, the height of the lower end of at least one baffle member is higher than the height of the upper end of the air inlet and lower than the height of the upper end of the exhaust port. The baffle member is provided in the interior space between the air inlet and the exhaust port, and is suspended from the ceiling of the building so that there is a space between the lower end and the floor of the building. In the equipment control step, the environmental equipment is controlled using the living body detection information to control the environment of the area where the livestock are actually present. In the equipment control step, the environmental equipment is controlled to control the environment of the location of the livestock tracked in the tracking calculation step. In at least one of the first calculation step and the second calculation step, calculation is performed using a trained classifier that has undergone machine learning.

[0012] A program according to one aspect of the present disclosure is a program for causing one or more processors to execute the sensible temperature calculation method.

[0013] A livestock house according to one aspect of the present disclosure includes the environmental control system and a building body to which the baffle member and the ventilation equipment are attached. [Brief explanation of the drawings]

[0015] (Embodiment 1) The sensible temperature calculation system, environmental control system, sensible temperature calculation method, and program according to embodiment 1 will be described below with reference to the drawings. Figures 2 and 3, which are referred to in the following embodiment, are schematic diagrams, and the ratios of the sizes and thicknesses of the components in the figures do not necessarily reflect the actual dimensional ratios.

[0016] (1) Temperature Sensation Calculation System The configuration of a sensible temperature calculation system 1 according to the first embodiment will be described with reference to the drawings.

[0017] The sensible temperature calculation system 1 according to the first embodiment includes an acquisition unit 11, a processing unit 12, an equipment control unit 13, a storage unit 14, and a notification control unit 15, as shown in FIG.

[0018] The sensible temperature calculation system 1 is used to determine the sensible temperature distribution of livestock 9 (see FIG. 3) in a space 7 (see FIG. 2) of a building 6 (see FIG. 2) in which the livestock 9 reside. A large number of livestock 9 reside in the space 7 (see FIG. 3).

[0019] (2) Buildings A building 6 in which the sensible temperature calculation system 1 is used will be described with reference to the drawings. Note that the building 6 shown in Fig. 2 is an example, and the building 6 in which the sensible temperature calculation system 1 is used is not limited to the example in Fig. 2.

[0020] 2, the building 6 includes a building body 61 having, for example, a rectangular parallelepiped shape. The building 6 also has a space 7.

[0021] In the example of FIG. 2, the building 6 is a livestock barn where livestock 9 are raised. When the building 6 is a livestock barn, the building body 61 is the livestock barn body. In the building 6, a large number of livestock 9 are raised in a space 7 (see FIG. 3). The livestock barn is, for example, a chicken barn where chickens are raised. However, the livestock barn is not limited to being a chicken barn, and may be a pig barn where pigs are raised as the livestock 9, or a cow barn where cows are raised as the livestock 9.

[0022] The building body 61 has two first side walls 62, 63 and two second side walls 64, 65.

[0023] The two first side walls 62, 63 are, for example, rectangular and are provided along the longitudinal direction D1 of the building 6. The two first side walls 62, 63 face each other in the lateral direction D2 of the building 6 with a space 7 interposed therebetween.

[0024] The two second side walls 64, 65 are, for example, rectangular and are provided along the short-side direction D2 of the building 6. The two second side walls 64, 65 face each other in the long-side direction D1 of the building 6 with the space 7 interposed therebetween.

[0025] The space 7 is a space surrounded by the building main body 61. More specifically, the space 7 is a space surrounded by two first side walls 62, 63 and two second side walls 64, 65 in a plan view in the height direction D3.

[0026] The building 6 also has multiple (two in the illustrated example) air intakes 66 and an exhaust vent 67. Air is supplied from outside the building 6 to the space 7 through each of the multiple air intakes 66. Air is exhausted from the space 7 to outside the building 6 through the exhaust vent 67.

[0027] The multiple air intakes 66 (air intakes 661, 662) are provided at the lower ends of the first side walls 62, 63 along the longitudinal direction D1 of the building 6. More specifically, one air intake 661 is provided at the lower end of the first side wall 62 at the first end side (the second side wall 64 side) in the longitudinal direction D1. The other air intake 662 is provided at the lower end of the first side wall 63 at the first end side (the second side wall 64 side) in the longitudinal direction D1. The one air intake 661 and the other air intake 662 face each other in the short direction D2 of the building 6.

[0028] The exhaust vent 67 is provided on the second end side (second side wall 65 side) in the longitudinal direction D1 of the building 6. The exhaust vent 67 is provided near the center of the second side wall 65 in the height direction D3. The exhaust vent 67 may also be provided near the upper end of the second side wall 65.

[0029] The number of air intake ports 66 is not limited to two, and may be one, or may be three or more. In other words, the number of air intake ports 66 must be one or more. The number of exhaust ports 67 is not limited to one, and may be two or more. In other words, the number of exhaust ports 67 must be one or more.

[0030] (3) Environmental control system 1, the environmental control system 2 according to the first embodiment includes a sensible temperature calculation system 1, a plurality of (two in the illustrated example) measuring devices 3, a control device 4, and environmental equipment 5. The environmental control system 2 according to the first embodiment further includes a detection device 33 and a notification device 21.

[0031] (3.1) Measuring equipment 2, the multiple measuring devices 3 measure environmental information that represents the environment of the space 7. The multiple measuring devices 3 measure physical quantities related to the environment at representative points 71 and 72 of the space 7 as the environmental information. The multiple measuring devices 3 output the measured environmental information to the sensible temperature calculation system 1.

[0032] The multiple measuring devices 3 include a measuring device 31 that measures physical quantities related to the environment of a representative point 71 of the space 7, and a measuring device 32 that measures physical quantities related to the environment of a representative point 72 of the space 7. The representative point 71 of the space 7 is an upwind position in the space 7. The representative point 71 is located closer to the air intake port 66 than to the air exhaust port 67 in the longitudinal direction D1 of the building 6. The distance between the representative point 71 and the air intake port 66 in the longitudinal direction D1 is shorter than the distance between the representative point 71 and the air exhaust port 67. The representative point 72 of the space 7 is located downwind in the space 7. The representative point 72 is located closer to the air exhaust port 67 than to the air intake port 66 in the longitudinal direction D1 of the building 6. The distance between the representative point 72 and the air exhaust port 67 in the longitudinal direction D1 is shorter than the distance between the representative point 72 and the air intake port 66.

[0033] Examples of physical quantities related to the environment of space 7 include temperature, humidity, wind speed, carbon dioxide concentration, ammonia concentration, and dust concentration. For example, when measuring temperature, each measuring device 3 includes a temperature sensor. When measuring humidity, each measuring device 3 includes a humidity sensor. When measuring wind speed, each measuring device 3 includes a wind speed sensor. Note that each measuring device 3 is not limited to measuring all of temperature, humidity, wind speed, carbon dioxide concentration, ammonia concentration, and dust concentration as physical quantities related to the environment of space 7. Each measuring device 3 only needs to measure at least one of temperature, humidity, wind speed, carbon dioxide concentration, ammonia concentration, and dust concentration as physical quantities related to the environment of space 7. In other words, each measuring device 3 only needs to include at least one sensor.

[0034] Dust concentration refers to the amount of dust contained in a space per unit volume. A large amount of dust tends to be generated in a space 7 where livestock 9 are present. Dust may affect the formation of body tissues of the livestock 9. For this reason, it is preferable to measure the dust concentration in the space 7.

[0035] (3.2) Control device 1 and 2, the control device 4 controls the environmental equipment 5 by outputting a control signal to the environmental equipment 5. More specifically, the control device 4 acquires the control content (control parameters) of the environmental equipment 5 from the sensible temperature calculation system 1. The control device 4 controls the environmental equipment 5 by outputting a control signal including the control content acquired from the sensible temperature calculation system 1 to the environmental equipment 5.

[0036] (3.3)Environmental equipment The environmental equipment 5 shown in Fig. 1 is equipment for controlling the environment of a space 7 (see Fig. 2). As shown in Fig. 1, the environmental equipment 5 includes a plurality of (two in the illustrated example) opening / closing windows 51 and a plurality of (three in the illustrated example) ventilation fans 52. The environmental equipment 5 controls the environment of the space 7 under the control of the control device 4.

[0037] (3.3.1) Openable window 2, the plurality of opening / closing windows 51 are provided in the air intake port 66 of the building 6. More specifically, of the plurality of opening / closing windows 51 (opening / closing windows 511, 512), one opening / closing window 511 is provided in the air intake port 661 of the first side wall 62, and the other opening / closing window 512 is provided in the air intake port 662 of the first side wall 63.

[0038] The multiple opening / closing windows 51 are also called tunnel doors, and open and close by rotating up and down. When the opening / closing windows 51 are opened, air can be introduced into the space 7 from outside the building 6 through the air intake vent 66.

[0039] (3.3.2) Ventilation fan 2, the multiple ventilation fans 52 are provided at the exhaust port 67. More specifically, the multiple ventilation fans 52 are provided on the opposite side to the opening / closing window 51 in the longitudinal direction D1. In other words, the multiple ventilation fans 52 are provided at the second side wall 65.

[0040] The ventilation fans 52 are arranged in a row in the short-side direction D2. More specifically, the ventilation fans 521, 522, and 523 are arranged in this order from the first side wall 63 side in the short-side direction D2.

[0041] The multiple ventilation fans 52 exhaust air from the space 7 of the building 6 to the outside of the building 6. More specifically, the multiple ventilation fans 52 are installed so that they exhaust air from the space 7 in substantially the same direction. This allows the air from the space 7 to be drawn in at a position on the exhaust side (downwind) of the space 7 and exhausted to the outside of the building 6.

[0042] (3.4) Detection device The detection device 33 shown in FIG. 1 detects the presence of livestock 9 (see FIG. 3). The detection device 33 includes, for example, an imaging device that captures an image of the space 7 and has the function of extracting the livestock 9 from the captured image. Alternatively, the detection device 33 includes, for example, an infrared sensor and has the function of receiving infrared rays emitted from the livestock 9. By having the above functions, the detection device 33 can detect areas in the space 7 where the livestock 9 are present or areas where there are many livestock 9. The detection device 33 outputs such detection results to the sensible temperature calculation system 1 as living body detection information.

[0043] (3.5) Notification device 1 notifies livestock 9 (see FIG. 3) that are present in an abnormal environment space and the position of the livestock 9 that are present in the abnormal environment space. The notification device 21 notifies information that should be notified in accordance with the control of the sensible temperature calculation system 1.

[0044] The notification device 21 has, for example, a display having a display function for displaying predetermined information. When the notification device 21 has a display, the notification device 21 can visually notify the livestock 9 present in the space of the abnormal environment and the position of the livestock 9 present in the space of the abnormal environment.

[0045] The notification device 21 has, for example, a speaker with an audio output function that outputs predetermined information by voice. When the notification device 21 has a speaker, the notification device 21 can audibly notify the livestock 9 present in the space of the abnormal environment and the position of the livestock 9 present in the space of the abnormal environment.

[0046] (4) Components of the sensible temperature calculation system Hereinafter, each component of the sensible temperature calculation system 1 according to the first embodiment will be described with reference to the drawings.

[0047] (4.1) Acquisition part As shown in Fig. 1, the acquisition unit 11 acquires the measurement results of the measurement device 3 from the measurement device 3 as environmental information of a space 7 (see Fig. 2) in which livestock 9 (see Fig. 3) exist. More specifically, the acquisition unit 11 acquires environmental information representing the environment at two representative points 71 and 72 (see Fig. 2) in the space 7 by wired or wireless communication. Here, the environmental information includes at least one of temperature, humidity, wind speed, carbon dioxide concentration, ammonia concentration, and dust concentration.

[0048] (4.2) Processing section 1, the processing unit 12 has a first calculation unit 121 and a second calculation unit 122. The processing unit 12 is configured as one function of a processor of a computer.

[0049] (4.2.1) First calculation section The first calculation unit 121 shown in FIG. 1 calculates an environmental distribution in the space 7 using environmental information about the space 7 (see FIG. 2). In the first embodiment, the environmental information includes information representing the environment at a plurality of representative points 71 and 72 (see FIG. 2) in the space 7. Specifically, there are two representative points 71 and 72. The two representative points 71 and 72 are an upwind position in the space 7 and a downwind position in the space 7. More specifically, as shown in FIG. 2, the representative point 71 is an upwind position in the space 7, and the representative point 72 is a downwind position in the space 7.

[0050] The first calculation unit 121 shown in FIG. 1 calculates the environmental distribution of the space 7 from the environmental information of the representative points 71 and 72, taking into consideration the layout of the space 7 of the building 6 and the positions of the representative points 71 and 72 in the space 7. For example, a function is prepared in advance that takes into consideration the layout of the space 7 and the positions of the representative points 71 and 72 in the space 7. The first calculation unit 121 calculates the environmental distribution of the space 7 by inputting the environmental information of the representative points 71 and 72 into the function. The function is stored in advance in the storage unit 14. Note that the method of calculating the environmental distribution by the first calculation unit 121 is not limited to the method using the function as described above, and other methods may be used.

[0051] (4.2.2) Second calculation section The second calculation unit 122 shown in FIG. 1 calculates the sensible temperature distribution of the livestock 9 using the environmental distribution calculated by the first calculation unit 121 and a calculation model.

[0052] Here, the sensible temperature distribution of the livestock 9 refers to the distribution of temperatures that the livestock 9 will experience in the space 7. It is difficult to measure the actual sensible temperature of the livestock 9, and when there are many livestock 9 in the space 7, it is even more difficult to measure the actual sensible temperature of each livestock 9. On the other hand, in order to measure the environmental temperature in the area where the livestock 9 are present, it is necessary to install temperature sensors in many places in the space 7.

[0053] Furthermore, as the livestock 9 grow, their heights change, and so the sensible temperature distribution in a two-dimensional area when viewed from above the building 6 is insufficient. Therefore, the second calculation unit 122 calculates the sensible temperature distribution of the livestock 9 as a three-dimensional distribution including not only the planar direction but also the height direction D3. This makes it possible to take into account the size of the livestock 9 at each growth stage, thereby improving the accuracy of the sensible temperature distribution of the livestock 9.

[0054] (4.2.3) Application of the processing unit In the processing unit 12 shown in Fig. 1, the second calculation unit 122 performs calculations using a classifier that has undergone machine learning. Note that it is not limited that only the second calculation unit 122 performs calculations using a classifier that has undergone machine learning. Only the first calculation unit 121 may perform calculations using a classifier that has undergone machine learning, or both the first calculation unit 121 and the second calculation unit 122 may perform calculations using classifiers that have undergone machine learning. In short, it is preferable that at least one of the first calculation unit 121 and the second calculation unit 122 performs calculations using a classifier that has undergone machine learning.

[0055] In the first embodiment, the first calculation unit 121 and the second calculation unit 122 shown in FIG. 1 perform calculations taking into account the airflow in the space 7 (see FIG. 2). The airflow in the space 7 is based on the layout of the building 6 (see FIG. 2), the opening degree of the opening / closing windows 51 (see FIG. 2), the ventilation capacity of the ventilation fan 52 (see FIG. 2), the wind speed upwind, and the wind speed downwind. Information regarding the airflow in the space 7 is pre-stored in the storage unit 14. Note that it is not limited that both the first calculation unit 121 and the second calculation unit 122 perform calculations taking into account the airflow in the space 7. Only the first calculation unit 121 may perform calculations taking into account the airflow in the space 7, or only the second calculation unit 122 may perform calculations taking into account the airflow in the space 7. In short, it is preferable that at least one of the first calculation unit 121 and the second calculation unit 122 perform calculations taking into account the airflow in the space 7.

[0056] 1 is not limited to calculating the sensible temperature distribution of the livestock 9 in the entire space 7, but may calculate it in only a part of the space 7. For example, the second calculation unit 122 calculates the sensible temperature distribution of the livestock 9 only in the area of ​​the space 7 where the livestock 9 are present. The second calculation unit 122 calculates the sensible temperature distribution of the livestock 9 using the living organism detection information and the environmental distribution of the space 7. The living organism detection information is information that indicates the presence of the livestock 9 in the space 7. The second calculation unit 122 acquires the living organism detection information from the detection device 33.

[0057] 3, the second calculation unit 122 calculates the sensible temperature distribution of the livestock 9 only for areas A1 and A4 in the space 7 where there are many livestock 9. On the other hand, the sensible temperature distribution for areas A2 and A3 is not calculated.

[0058] 1 may have a function of tracking the position of the livestock 9. As shown in FIG. 1, the processing unit 12 has a tracking calculation unit 123. The tracking calculation unit 123 tracks the position of the livestock 9 using position information indicating the position of the livestock 9. The tracking calculation unit 123 acquires the position information from the detection device 33.

[0059] 1, the processing unit 12 further includes an abnormality detection unit 124. The abnormality detection unit 124 detects livestock 9 that exist in an abnormal environment space in the space 7. More specifically, the abnormality detection unit 124 uses the detection result of the detection device 33 to detect livestock 9 that exist in an abnormal environment space.

[0060] (4.3) Equipment Control Unit The equipment control unit 13 shown in Fig. 1 controls the environmental equipment 5 (plurality of opening / closing windows 51 and plural ventilation fans 52). More specifically, the equipment control unit 13 controls the environmental equipment 5 based on the sensible temperature calculated by the second calculation unit 122 of the processing unit 12 so that the actual sensible temperature of the livestock 9 becomes a temperature suitable for the livestock 9. In the first embodiment, the equipment control unit 13 outputs the control content (control parameters) of the environmental equipment 5 to the control device 4. The environmental equipment 5 controls the environment of the space 7 based on the sensible temperature distribution calculated by the second calculation unit 122 so that the actual sensible temperature of the livestock 9 becomes a temperature suitable for the livestock 9.

[0061] Incidentally, when the second calculation unit 122 calculates the sensible temperature distribution using the living body detection information, the equipment control unit 13 controls the environmental equipment 5 using the living body detection information to control the environment of the area where the livestock 9 actually exist. This makes it possible to control the environment of the area in the space 7 where the livestock 9 actually exist, giving priority to that area over an area where the livestock 9 do not exist. As a result, the environment can be controlled efficiently.

[0062] Furthermore, the equipment control unit 13 controls the environmental equipment 5 so as to control the environment of the position of the livestock 9 tracked by the tracking calculation unit 123. This makes it possible to precisely control the environment of the area where the livestock 9 actually exist.

[0063] (4.4) Notification control section 1 controls the alarm device 21 so that, when the abnormality detection unit 124 detects livestock 9 present in the space with an abnormal environment, the alarm control unit 15 controls the alarm device 21 to notify the livestock 9 present in the space with an abnormal environment and the position of the livestock 9 present in the space with an abnormal environment via the alarm device 21. This allows early action to be taken against the livestock 9 present in the space with an abnormal environment.

[0064] (4.5) Storage section 1 stores a calculation model used by the processing unit 12. More specifically, the storage unit 14 stores a plurality of parameters used in the calculation model.

[0065] The storage unit 14 also stores the environmental distribution of the space 7 calculated by the first calculation unit 121. The storage unit 14 stores history data of the environmental distribution of the space 7 (the calculation result of the first calculation unit 121). The history data of the environmental distribution of the space 7 is, for example, a combination of the environmental distribution of the space 7 and the time points at which physical quantities related to the environmental information used in the calculation of the environmental distribution were measured.

[0066] Furthermore, the memory unit 14 stores the sensible temperature distribution of the livestock 9 calculated by the second calculation unit 122. The memory unit 14 stores historical data of the sensible temperature distribution of the livestock 9 (the calculation result of the second calculation unit 122). The historical data of the sensible temperature distribution of the livestock 9 includes, for example, a combination of the environmental distribution of the space 7 and the sensible temperature distribution of the livestock 9 at the time when the environmental distribution is obtained.

[0067] (4.6) Computational Model The computational model used in the processing unit 12 shown in Fig. 1 is a trained model trained using a plurality of data. The computational model is a model for causing one or more processors to function so that, for example, an environmental distribution in a space 7 (see Fig. 2) is input to an input layer 81 (see Fig. 4) of a neural network 8 (see Fig. 4) and a sensible temperature distribution of livestock 9 is output from an output layer 82 (see Fig. 4) of the neural network 8.

[0068] The computational model is trained using a plurality of pieces of historical data, each of which includes a combination of an environmental distribution in the space 7 and a sensible temperature distribution of the livestock 9 at the time the environmental information is obtained.

[0069] In the case of the neural network 8 shown in Fig. 4, the computational model is trained using multiple historical data as supervised data. When an environmental distribution is input to the input layer 81 of the neural network 8, each parameter is adjusted so that a sensible temperature distribution is output from the output layer 82 of the neural network 8.

[0070] By using such a computational model (trained model), the actual sensible temperature of the livestock 9 throughout the space 7 can be made closer to a temperature suitable for the livestock 9.

[0071] (5) Operation of the environmental control system The operation (sensible temperature calculation method) of the environmental control system 2 according to the first embodiment will be described below with reference to FIG.

[0072] In a first step, the multiple measurement devices 3 measure environmental information of the space 7 (S1 in FIG. 4). More specifically, the measurement device 31 measures predetermined physical quantities related to the environment at multiple representative points 71 in the space 7, and the measurement device 32 measures predetermined physical quantities related to the environment at multiple representative points 72 in the space 7.

[0073] In a second step, in the sensible temperature calculation system 1, the processing unit 12 calculates the environmental distribution of the space 7 using the sensor values ​​(environmental information of the representative points 71, 72) of the sensors of the measuring devices 31, 32 (S2 in FIG. 4). The processing unit 12 calculates, as the environmental distribution of the space 7, for example, the temperature distribution of the space 7, the humidity distribution of the space 7, and the wind speed distribution of the space 7. The second step corresponds to the first calculation step.

[0074] In the third step, the environmental distribution calculated in the second step and the calculation model are used to calculate the sensible temperature distribution of the livestock 9 in the space 7. The third step corresponds to the second calculation step.

[0075] Specifically, in the third step, the processing unit 12 inputs the environmental distribution of the space 7 into the input layer 81 of the neural network 8, and outputs the sensible temperature distribution of the livestock 9 in the space 7 from the output layer 82 of the neural network 8 (S3 in Figure 4).

[0076] In the fourth step, the equipment control unit 13 outputs the control content based on the sensible temperature distribution calculated by the processing unit 12 to the control device 4, thereby controlling the environmental equipment 5 (multiple opening / closing windows 51 and multiple ventilation fans 52) (S4 in Figure 4).

[0077] In the fifth step, the environmental equipment 5 operates under the control of the control device 4 (S5 in FIG. 4).

[0078] A program for causing one or more processors to execute the sensible temperature calculation method having the second step, the third step, and the fourth step is stored in the storage unit 14 of the sensible temperature calculation system 1.

[0079] (6) Effects The sensible temperature calculation system 1 according to the first embodiment calculates the sensible temperature distribution of the livestock 9 in the space 7 using the environmental distribution of the space 7. By controlling the environment of the space 7 in consideration of the sensible temperature distribution calculated by the first calculation unit 121, it is possible to make the actual sensible temperatures of the livestock 9 throughout the space 7 approach a temperature suitable for the livestock 9.

[0080] In the sensible temperature calculation system 1 according to the first embodiment, the environmental information includes at least one of temperature, humidity, and wind speed. As a result, when calculating the sensible temperature distribution of the livestock 9, the accuracy of the sensible temperature distribution of the livestock 9 can be improved by using physical quantities that are likely to affect the sensible temperature of the livestock 9.

[0081] In the sensible temperature calculation system 1 according to the first embodiment, the environmental information represents the environment at at least one representative point 71, 72 in the space 7. This reduces the number of measurement points for the environmental information, and therefore reduces the number of measurement devices 3 that measure the environmental information.

[0082] In the sensible temperature calculation system 1 according to the first embodiment, the plurality of representative points 71, 72 include an upwind position in the space 7 and a downwind position in the space 7. This increases the accuracy of the environmental distribution in the space 7, and therefore makes it possible to accurately calculate the sensible temperature distribution of the livestock 9.

[0083] The sensible temperature calculation system 1 according to the first embodiment calculates the sensible temperature distribution of the livestock 9 using living body detection information indicating the presence of the livestock 9 and the environmental distribution of the space 7. As a result, when calculating the sensible temperature distribution of the livestock 9, it is possible to give priority to areas in the space 7 where the livestock 9 actually exist over areas where the livestock 9 do not exist.

[0084] The sensible temperature calculation system 1 according to the first embodiment uses the living body detection information to control the environmental equipment 5 so as to control the environment of the area where the livestock 9 actually exist. This allows the environment to be controlled by prioritizing the area where the livestock 9 actually exist in the space 7 over the area where the livestock 9 do not exist. As a result, the environment can be controlled efficiently.

[0085] The sensible temperature calculation system 1 according to the first embodiment detects and tracks the position of the livestock 9 in the space 7. This makes it possible to precisely control the environment of the area in which the livestock 9 actually exist.

[0086] In the sensible temperature calculation system 1 according to the first embodiment, the second calculation unit 122 calculates the sensible temperature distribution of the livestock 9 as a three-dimensional distribution. This allows the size of the livestock 9 at each growth stage to be taken into consideration, thereby improving the accuracy of the sensible temperature distribution of the livestock 9.

[0087] The sensible temperature calculation system 1 according to the first embodiment detects livestock 9 present in an abnormal environment space and controls the alarm device 21 to notify at least one of the livestock 9 present in the abnormal environment space and the location of the livestock 9 present in the abnormal environment space. This allows for early response to the livestock 9 present in the abnormal environment space.

[0088] In the sensible temperature calculation system 1 according to the first embodiment, at least one of the first calculation unit 121 and the second calculation unit 122 performs calculations using a classifier that has undergone machine learning. This makes it possible to calculate the sensible temperature distribution based on the history in a short time.

[0089] (7) Variations A modification of the first embodiment will be described below.

[0090] As a modification of the first embodiment, the number of representative points of the environment included in the environment information is not limited to a plurality of representative points, and may be one. In other words, the number of representative points needs to be at least one. The environment information includes information that represents the environment at at least one representative point in the space 7.

[0091] As another variation of the first embodiment, the environmental equipment 5 may include an air conditioning device. The air conditioning device is installed in the building 6 and adjusts the temperature of the space 7 of the building 6 by discharging warm air or cool air into the space 7.

[0092] As yet another modification of the first embodiment, the space 7 is not limited to being an internal space of the building 6, but may be an open space.

[0093] As a modification of the first embodiment, when livestock 9 present in a space with an abnormal environment is detected, the notification control unit 15 is not limited to controlling the notification device 21 to notify both the livestock 9 present in the space with an abnormal environment and the position of the livestock 9 present in the space with an abnormal environment. The notification control unit 15 may control the notification device 21 to notify only the livestock 9 present in the space with an abnormal environment, or may control the notification device 21 to notify only the position of the livestock 9 present in the space with an abnormal environment. In short, when livestock 9 present in a space with an abnormal environment is detected by the abnormality detection unit 124, it is preferable that the notification control unit 15 controls the notification device 21 to notify at least one of the livestock 9 present in the space with an abnormal environment and the position of the livestock 9 present in the space with an abnormal environment.

[0094] The notification device 21 notifies information in accordance with instructions from the notification control unit 15, and therefore the notification device 21 is not limited to notifying both livestock 9 present in the space with an abnormal environment and the positions of the livestock 9 present in the space with an abnormal environment. The notification device 21 may notify only livestock 9 present in the space with an abnormal environment, or may notify only the positions of the livestock 9 present in the space with an abnormal environment. In short, it is preferable that the notification device 21 notify at least one of livestock 9 present in the space with an abnormal environment and the positions of the livestock 9 present in the space with an abnormal environment.

[0095] In the first embodiment, as described above, the computational model (trained model) used in the processing unit 12 is generated by machine learning. The processing unit 12 may be implemented as any type of artificial intelligence or system. Here, the machine learning algorithm is, for example, a neural network. However, the machine learning algorithm is not limited to a neural network and may be, for example, an XGB (eXtreme Gradient Boosting) regression, a random forest, a decision tree, a logistic regression, a support vector machine (SVM), a naive Bayes classifier, or k-nearest neighbors. Furthermore, the machine learning algorithm may be, for example, a Gaussian Mixture Model (GMM), k-means clustering, or the like.

[0096] In addition, the learning method is supervised learning as an example in the first embodiment. However, the learning method is not limited to supervised learning, and may be unsupervised learning or reinforcement learning.

[0097] The sensible temperature calculation systems according to the above-described modifications also achieve the same effects as the sensible temperature calculation system 1 according to the first embodiment.

[0098] The executing entity of the sensible temperature calculation system 1 or the sensible temperature calculation method of the present disclosure includes a computer system. The computer system is primarily composed of a processor and memory as hardware. The processor executes a program stored in the memory of the computer system to realize the functions of the executing entity of the sensible temperature calculation system 1 or the sensible temperature calculation method of the present disclosure. The program may be pre-stored in the memory of the computer system, provided via a telecommunications line, or provided by being recorded on a non-transitory recording medium readable by the computer system, such as a memory card, optical disk, or hard disk drive. The processor of the computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). The multiple electronic circuits may be integrated into a single chip or distributed across multiple chips. The multiple chips may be integrated into a single device or distributed across multiple devices.

[0099] Furthermore, in the first embodiment, the sensible temperature calculation system 1 includes the acquisition unit 11, the processing unit 12, the equipment control unit 13, the storage unit 14, and the notification control unit 15, but the acquisition unit 11, the equipment control unit 13, the storage unit 14, and the notification control unit 15 are not essential components of the sensible temperature calculation system 1. In other words, the sensible temperature calculation system 1 only needs to include the processing unit 12, and at least one of the acquisition unit 11, the equipment control unit 13, the storage unit 14, and the notification control unit 15 does not have to be included as a component of the sensible temperature calculation system 1.

[0100] The sensible temperature calculation system 1 may be implemented as a single device housed in a single housing, or as two or more devices. At least one of the acquisition unit 11, processing unit 12, equipment control unit 13, memory unit 14, and notification control unit 15 may be provided separately from the remaining acquisition unit 11, processing unit 12, equipment control unit 13, memory unit 14, and notification control unit 15. For example, the processing unit 12 may be provided separately from the equipment control unit 13. Furthermore, the functions of the acquisition unit 11, processing unit 12, equipment control unit 13, memory unit 14, and notification control unit 15 may be provided separately in multiple devices. For example, at least one of the first calculation unit 121, second calculation unit 122, tracking calculation unit 123, and anomaly detection unit 124 may be provided separately from the remaining first calculation unit 121, second calculation unit 122, tracking calculation unit 123, and anomaly detection unit 124. At least some of the functions of the sensible temperature calculation system 1 may be implemented, for example, by cloud computing.

[0101] (Embodiment 2) A control system according to embodiment 2 will be described below with reference to the drawings. Figures 5, 6, 7A, 7B, 9, and 10, which are referred to in the following embodiments, are schematic diagrams, and the ratios of sizes and thicknesses of the components in the figures do not necessarily reflect the actual dimensional ratios.

[0102] (1) Control system The configuration of a control system 100 according to the second embodiment will be described with reference to the drawings.

[0103] 5 and 6, the control system 100 according to the second embodiment includes a plurality of baffle members 2A (three in the illustrated example), an environmental facility (ventilation facility) 5, and a control device 4. The control system 100 according to the second embodiment controls the wind speed of air in an internal space (space 7).

[0104] The control system 100 is a system that controls the wind speed of air in the internal space (space 7) of the building 6. The control system 100 is used in a barn or the like where livestock 9 are raised. The barn is, for example, a chicken house where chickens are raised. However, the barn is not limited to a chicken house, and may be a pig house where pigs are raised as livestock 9, or a cow barn where cows are raised as livestock 9.

[0105] (2) Buildings The building 6 in which the control system 100 is installed will be described with reference to the drawings.

[0106] 5 and 6, the building 6 includes, for example, a rectangular parallelepiped building main body 61. The building 6 also has an interior space (space 7). The building 6 also includes a control system 100.

[0107] In the example of Fig. 5, the building 6 is a livestock barn. When the building 6 is a livestock barn, the building body 61 is the livestock barn body. In the building 6, a large number of livestock 9 are raised in the internal space (space 7).

[0108] The building main body 61 has two first side walls 62, 63 and two second side walls 64, 65. The building main body 61 has a plurality of baffle members 2A and environmental equipment (ventilation equipment) 5 attached thereto.

[0109] The two first side walls 62, 63 are, for example, rectangular and are provided along the longitudinal direction D1 of the building 6. The two first side walls 62, 63 face each other in the lateral direction D2 of the building 6 with an internal space (space 7) interposed between them.

[0110] The two second side walls 64, 65 are, for example, rectangular and are provided along the short-side direction D2 of the building 6. The two second side walls 64, 65 face each other in the long-side direction D1 of the building 6 with an internal space (space 7) between them.

[0111] The internal space (space 7) is a space surrounded by the building main body 61. More specifically, the internal space (space 7) is a space surrounded by two first side walls 62, 63 and two second side walls 64, 65.

[0112] The building 6 also has multiple (two in the illustrated example) air intake ports 66 and an exhaust port 67. Air is drawn into the internal space (space 7) from outside the building 6 through each of the multiple air intake ports 66. Air is exhausted from the internal space (space 7) to outside the building 6 through the exhaust port 67.

[0113] The multiple air intakes 66 (air intakes 661, 662) are provided at the lower ends of the first side walls 62, 63 along the longitudinal direction D1 of the building 6. More specifically, one air intake 661 is provided at the lower end of the first side wall 62 on the first end side (second side wall 64 side) in the longitudinal direction D1. The other air intake 662 is provided at the lower end of the first side wall 63 on the first end side in the longitudinal direction D1. The one air intake 661 and the other air intake 662 face each other in the short direction D2 of the building 6.

[0114] The exhaust vent 67 is provided on the second end side (second side wall 65 side) in the longitudinal direction D1 of the building 6. More specifically, the exhaust vent 67 is provided near the center of the second side wall 65. Note that the exhaust vent 67 may also be provided near the upper end of the second side wall 65.

[0115] The number of air intake ports 66 is not limited to two, and may be one, or may be three or more. In other words, the number of air intake ports 66 must be one or more. The number of exhaust ports 67 is not limited to one, and may be two or more. In other words, the number of exhaust ports 67 must be one or more.

[0116] (3) Components of the control system Hereinafter, each component of the control system 100 according to the second embodiment will be described with reference to the drawings.

[0117] (3.1) Baffle member As shown in FIGS. 5 and 6, multiple baffle members 2A are provided between an air intake port 66 and an air exhaust port 67 in the interior space (space 7) of the building 6. In the example of FIG. 5, there are three baffle members 2A. Each baffle member 2A is suspended from a ceiling 69 of the building 6 so that a space 73 is formed between a lower end 20A of the baffle member 2A and a floor surface 68 of the building 6. In other words, each baffle member 2A is suspended from the ceiling 69 within a range that does not contact the floor surface 68 of the building 6. Each baffle member 2A is formed, for example, from a translucent or transparent material.

[0118] Each of the plurality of baffle members 2A is provided so as to block a part of the longitudinal direction D1 in the internal space (space 7). That is, the plurality of baffle members 2A block air from flowing along the longitudinal direction D1.

[0119] In the interior space (space 7), the wind speed of the air passing through the position where the baffle member 2A is installed is higher than the wind speed of the air passing through the position where the baffle member 2A is not installed. Also, the larger the space 73 between the floor surface 68 of the building 6 and the lower end 20A of the baffle member 2A, the lower the wind speed of the air passing through the space 73.

[0120] Each baffle member 2A in the second embodiment is a plate installed in the interior space (space 7) of the building 6 so that its normal direction is along a direction (longitudinal direction D1) perpendicular to the height direction D3 of the building 6. This makes it difficult for the baffle member 2A to deform even when exposed to air, allowing for stable control of the air velocity.

[0121] The multiple baffle members 2A include a first baffle member 21A, a second baffle member 22A, and a third baffle member 23A. The first baffle member 21A, the second baffle member 22A, and the third baffle member 23A are arranged in this order from the second side wall 64 side at intervals in the longitudinal direction D1 of the building 6. Of the multiple baffle members 2A, the first baffle member 21A is arranged closest to the air intake port 66 in the longitudinal direction D1. On the other hand, the third baffle member 23A is arranged closest to the air exhaust port 67 in the longitudinal direction D1.

[0122] The baffle member 2A is arranged so that the wind speed is uniform in the region between the baffle member 2A and the exhaust port 67 in the interior space (space 7) of the building 6. In other words, the baffle member 2A is arranged so that the difference in wind speed between positions in the region between the baffle member 2A and the exhaust port 67 in the interior space (space 7) of the building 6 is reduced. This allows the heat in the interior space (space 7) of the building 6 to be smoothly discharged to the outside of the building 6.

[0123] Here, "uniform wind speed" means that the variation in wind speed is 1.0 m / s or less. More preferably, the variation in wind speed is 0.5 m / s or less. Furthermore, it is preferable that the variation in wind speed is 20% or less of the average wind speed.

[0124] As described above, three or more baffle members 2A are provided. The distance between two adjacent baffle members 2A among the three or more baffle members 2A is uniform. In other words, the distance L1 between the first baffle member 21A and the second baffle member 22A is the same as the distance L2 between the second baffle member 22A and the third baffle member 23A.

[0125] In addition, when there are three or more baffle members 2A, the distance between two adjacent baffle members 2A may be uneven. In other words, the distance L1 between the first baffle member 21A and the second baffle member 22A may be different from the distance L2 between the second baffle member 22A and the third baffle member 23A. This makes it possible to control the wind speed according to the conditions of the building 6 and the interior space (space 7) of the building 6.

[0126] Furthermore, two or more baffle members 2A are provided, and the heights of the two or more baffle members 2A are uniform. In other words, the height T1 of the first baffle member 21A is the same as the height T2 of the second baffle member 22A and the height T3 of the third baffle member 23A. Here, the "height of the baffle member" refers to the height from the floor 68 of the building 6 to the lower end of the baffle member 2A. More specifically, the height T1 of the first baffle member 21A is the height from the floor 68 of the building 6 to the lower end 210A of the first baffle member 21A. The height T2 of the second baffle member 22A is the height from the floor 68 of the building 6 to the lower end 220A of the second baffle member 22A. The height T3 of the third baffle member 23A is the height from the floor 68 of the building 6 to the lower end 230A of the third baffle member 23A.

[0127] The heights of two or more baffle members 2A may be uneven. In other words, the height T1 of the first baffle member 21A, the height T2 of the second baffle member 22A, and the height T3 of the third baffle member 23A may be different from one another. Alternatively, any one of the height T1 of the first baffle member 21A, the height T2 of the second baffle member 22A, and the height T3 of the third baffle member 23A may be different from the remaining two. This allows wind speed control to be performed according to the conditions of the building 6 and the interior space (space 7) of the building 6. In particular, when a ventilation fan 52 is provided at the exhaust port 67, the air in the area closer to the exhaust port 67 has higher kinetic energy than the air in the area closer to the air intake port 66. Therefore, even if the space 733 (see Figure 7) between the third baffle member 23A and the floor surface 68 is large, the air passing through the space 733 has a higher wind speed than the air passing through the space 731 (see Figure 7) between the first baffle member 21A and the floor surface 68 and the air passing through the space 732 (see Figure 7) between the second baffle member 22A and the floor surface 68.

[0128] The number of baffle members 2A is not limited to three. The number of baffle members 2A may be only one, only two, or four or more. In short, it is sufficient for the control system 100 to be equipped with at least one baffle member 2A.

[0129] (3.2) Environmental equipment (ventilation equipment) As shown in FIGS. 5 and 6, the environmental equipment (ventilation equipment) 5 includes a plurality of (two in the illustrated example) opening / closing windows 51 and a plurality of (five in the illustrated example) ventilation fans 52.

[0130] (3.2.1) Openable window 5 and 6, the multiple opening / closing windows 51 are provided in an air intake port 66 of the building 6. More specifically, of the multiple opening / closing windows 51 (opening / closing windows 511, 512), one opening / closing window 511 is provided in an air intake port 661 of a first side wall 62 provided along the longitudinal direction D1, and the other opening / closing window 512 is provided in an air intake port 662 of a first side wall 63 provided along the longitudinal direction D1.

[0131] The multiple opening / closing windows 51 are also called tunnel doors, and open and close by rotating up and down. When the opening / closing windows 51 are opened, air can be let into the interior space (space 7) from outside the building 6 through the air intake port 66.

[0132] (3.2.2) Ventilation fan 5 and 6, the multiple ventilation fans 52 are provided at the exhaust port 67. More specifically, the multiple ventilation fans 52 are provided on the opposite side to the opening / closing window 51 in the longitudinal direction D1. In other words, the multiple ventilation fans 52 are provided at the second side wall 65.

[0133] The multiple ventilation fans 52 are lined up in a row in the short-side direction D2. More specifically, in the short-side direction D2, ventilation fan 521, ventilation fan 522, ventilation fan 523, ventilation fan 524, and ventilation fan 525 are lined up in this order from the first side wall 63 side.

[0134] The multiple ventilation fans 52 exhaust air from the internal space (space 7) of the building 6 to the outside of the building 6. More specifically, the multiple ventilation fans 52 are installed so that the air from the internal space (space 7) is exhausted in substantially the same direction. This allows the air from the internal space (space 7) to be drawn in on the exhaust side and exhausted to the outside of the building 6.

[0135] (3.3) Control device 5 has a function of controlling a plurality of ventilation fans 52. More specifically, the control device 4 individually controls the plurality of ventilation fans 52. The control device 4 also has a function of receiving an input of the outside air temperature outside the building 6.

[0136] The control device 4 controls the plurality of ventilation fans 52 in accordance with the outside air temperature input to the control device 4. More specifically, the control device 4 adjusts the number of ventilation fans 52 to be operated among the plurality of ventilation fans 52 in accordance with the outside air temperature.

[0137] Specifically, the higher the outside air temperature input to the control device 4, the more ventilation fans 52 to operate out of the plurality of ventilation fans 52. On the other hand, the lower the outside air temperature input to the control device 4, the less ventilation fans 52 to operate out of the plurality of ventilation fans 52. This makes it possible to maintain the air speed in the interior space (space 7) of the building 6 within a desired speed range, even if the outside air temperature outside the building 6 fluctuates.

[0138] The control device 4 may obtain the outside air temperature by manual input, or may obtain the outside air temperature by automatic input from a temperature sensor installed near the outside of the building 6. When the control device 4 obtains the outside air temperature by manual input, the accuracy of the outside air temperature is often higher because a person can manually correct the outside air temperature of the building 6. On the other hand, when the control device 4 obtains the outside air temperature by automatic input from a temperature sensor, it becomes possible to automatically control the air speed in the internal space (space 7) 24 hours a day.

[0139] (4) Control method A control method according to embodiment 2 will be described below with reference to Figures 7A and 7B. The control method according to embodiment 2 is a method for controlling the wind speed of air in the interior space (space 7) of building 6. Figure 7A shows the distribution of wind speed according to the control method according to embodiment 2. Figure 7B shows the distribution of wind speed according to a comparative example. The height from floor 68 (see Figure 6) of building 6 to the lower end 20A (see Figure 6) of each baffle member 2A is 1.5 m. The wind speeds shown in Figures 7A and 7B are those at a position 300 mm above floor 68.

[0140] As shown in FIG. 7B, the comparative example is an example in which a baffle member 2A is not provided in the internal space (space 7A) of the building 6A. In the comparative example, since a baffle member 2A is not provided, the air velocity in the internal space (space 7A) is low. For example, in the main region of the internal space (space 7A), the air velocity at a height of 300 mm from the floor surface 68 is approximately 1.0 m / s. Here, the "main region of the internal space (space 7A)" refers to the region of the internal space (space 7A) excluding the regions in which the air intake vent 66 (see FIG. 5) and the air exhaust vent 67 (see FIG. 5) are provided, and refers to the region near the center in the short-side direction D2. In other words, the regions at both ends in the short-side direction D2 are not included in the main region of the internal space (space 7A). If the building 6A is a livestock barn, the main region of the internal space (space 7A) is the region where many livestock 9 reside.

[0141] On the other hand, in the control method according to the second embodiment, a plurality of baffle members 2A are provided as shown in Fig. 6. The plurality of baffle members 2A are suspended from a ceiling 69 of the building 6 between an air intake port 66 (see Fig. 5) and an exhaust port 67 (see Fig. 5) in the interior space (space 7) of the building 6 so that a space 73 is formed between the lower end 20A of the baffle member 2A and a floor surface 68 of the building 6. As described above, the air intake port 66 is an opening through which air is supplied from the outside of the building 6 to the interior space (space 7). As described above, the exhaust port 67 is an opening through which air is exhausted from the interior space (space 7) to the outside of the building 6.

[0142] In this case, in space 73 where baffle member 2A is provided, the cross-sectional area of ​​space 73 is smaller than the cross-sectional area of ​​the remaining space, and therefore, as shown in FIG. 7A, the wind speed of the air passing through space 73 increases. More specifically, in the case of FIG. 7A, the wind speed of the air can be increased in the space between first baffle member 21A, which is closest to air intake port 66, and third baffle member 23A, which is closest to air exhaust port 67, in the internal space (space 7) of building 6. For example, in the main region of internal space (space 7), the wind speed of the air at a height of 300 mm from floor surface 68 is approximately 2.5 m / s. This increases the wind speed of the air in internal space (space 7) compared to when baffle member 2A is not provided, making it easier to discharge heat retained in internal space (space 7) to the outside. Here, the "main area of ​​the internal space (space 7)" refers to the area of ​​the internal space (space 7) between the first baffle member 21A closest to the air intake port 66 and the third baffle member 23A closest to the air exhaust port 67, and refers to the area near the center in the short direction D2. In other words, the areas at both ends in the short direction D2 are not included in the main area of ​​the internal space (space 7). If the building 6 is a livestock barn, the main area of ​​the internal space (space 7) is the area where many livestock 9 reside.

[0143] In the second embodiment, when intake air taken in through the opening / closing window 51 is sucked out by the ventilation fan 52 and exhausted, a spiral airflow is generated in the interior space (space 7). As this spiral airflow travels from the opening / closing window 51 toward the ventilation fan 52, it hits the lower end 20A of the baffle member 2A and increases in wind speed. The airflow then loses speed before reaching the next baffle member 2A, but increases in speed again when it hits the next baffle member 2A. This allows the spiral airflow to be controlled to a substantially constant wind speed at any position within the interior space (space 7) of the long and narrow building 6.

[0144] For example, if building 6 is a chicken coop, the industry's poultry farming instruction manual states that a comfortable wind speed for chickens is approximately 3.0 to 4.0 m / s. Therefore, it is desirable for the wind speed in the interior space (space 7) to be maintained within this range. In the example of Figure 7A, the air speed at a height of 300 mm from floor 68 increases to 1.0 to 2.5 m / s. The height of 300 mm from floor 68 is approximately the height of a cockscomb. This increases the cooling effect on the chickens.

[0145] At this time, the multiple baffle members 2A can make the air speed uniform in the space between first baffle member 21A and third baffle member 23A in the internal space (space 7). In the example of Fig. 7B, the wind speed at a height of 300 mm from floor surface 68 is 1.0 m / s to 2.0 m / s, whereas in the example of Fig. 7A, the wind speed at a height of 300 mm from floor surface 68 is 2.5 m / s to 3.0 m / s. In the example of Fig. 7A, the variation in wind speed is smaller than in the example of Fig. 7B.

[0146] (5) Effects In the control system 100 according to the second embodiment, a baffle member 2A is provided in the interior space (space 7) of the building 6, suspended from the ceiling 69 of the building 6 so as to define a space 73 between the lower end 20A and the floor surface 68 of the building 6. This narrows the space 73 between the lower end 20A of the baffle member 2A and the floor surface 68, thereby increasing the wind speed when air passes through the space 73. As a result, heat retained in the interior space (space 7) of the building 6 can be more easily discharged to the outside of the building 6.

[0147] When the control system 100 is used in a barn for raising livestock 9, it is possible to reduce stress on the livestock 9 caused by heat accumulating in the internal space (space 7). In particular, since chickens are covered entirely with feathers and do not have sweat glands, when the livestock 9 is a chicken, it is important to expel heat accumulating in the internal space (space 7) to prevent the internal space (space 7) from becoming too hot.

[0148] In the control system 100 according to the second embodiment, the baffle member 2A is arranged so as to reduce the difference in wind speed between positions in the region between the baffle member 2A and the exhaust port 67. This allows the heat in the interior space (space 7) of the building 6 to be smoothly discharged to the outside of the building 6.

[0149] In the control system 100 according to the second embodiment, an opening / closing window 51 is provided in an air supply port 66 provided at the lower end of first side walls 62, 63 along the longitudinal direction D1 of the building 6. This makes it possible to adjust the amount of air supplied from the air supply port 66 to the internal space (space 7) depending on the opening / closing degree of the opening / closing window 51.

[0150] In the control system 100 according to the second embodiment, the interval between two adjacent baffle members 2A may be uneven. This allows wind speed control to be performed according to the state of the building 6 and the interior space (space 7) of the building 6.

[0151] In the control system 100 according to the second embodiment, the heights of two or more baffle members 2A may be uneven. This allows wind speed control to be performed according to the state of the building 6 and the interior space (space 7) of the building 6.

[0152] In the control system 100 according to the second embodiment, a ventilation fan 52 that exhausts air from the internal space (space 7) to the outside of the building 6 is provided at the exhaust port 67. This allows air to be drawn into the internal space (space 7) on the exhaust side and exhausted to the outside of the building 6.

[0153] In the control system 100 according to the second embodiment, the higher the outside temperature outside the building 6, the more ventilation fans 52 are operated, and the lower the outside temperature, the less ventilation fans 52 are operated. This makes it possible to maintain the air velocity in the interior space (space 7) of the building 6 within a desired velocity range, even if the outside temperature outside the building 6 fluctuates.

[0154] In the control system 100 according to the second embodiment, the building 6 is a livestock barn. This reduces the accumulation of heat even in the interior space (space 7) of the barn, thereby reducing stress on the livestock 9 caused by heat. As a result, a comfortable environment for raising the livestock 9 can be provided.

[0155] There is a system that irradiates light of 550 nm to 650 nm, which can suppress the temperature rise inside the poultry house (the interior space of the building) and the poultry (building) more effectively than infrared rays, but this system does not have the function of expelling heat from the poultry house. In other words, this system does not have the function of controlling the air flow inside the poultry house.

[0156] According to the control system 100 of the second embodiment, the wind speed of the air in the interior space (space 7) of the building 6 can be increased.

[0157] (6) Variations A modification of the second embodiment will be described below.

[0158] As a first modification of the second embodiment, the control system 100a may further include a plurality of (three in the illustrated example) suspension mechanisms 9A as shown in Fig. 8. The plurality of suspension mechanisms 9A can move the plurality of baffle members 2A in the height direction D3 (see Fig. 6) of the building 6 (see Fig. 6).

[0159] In the case of the first modified example, each baffle member 2A is a flexible member such as a vinyl sheet. Examples of each baffle member 2A include structures such as a roll curtain and a drop curtain.

[0160] The multiple hanging mechanisms 9A correspond one-to-one to the multiple baffle members 2A. More specifically, the multiple hanging mechanisms 9A include a first hanging mechanism 91A, a second hanging mechanism 92A, and a third hanging mechanism 93A. The first hanging mechanism 91A corresponds to the first baffle member 21A, the second hanging mechanism 92A corresponds to the second baffle member 22A, and the third hanging mechanism 93A corresponds to the third baffle member 23A. Each hanging mechanism 9A has the function of moving the corresponding baffle member 2A in the height direction D3 of the building 6. If the baffle members 2A are roller curtains, each hanging mechanism 9A can change the position of the lower end 20A (see FIG. 6) of the baffle member 2A in the height direction D3 by rolling up the corresponding baffle member 2A. When the baffle members 2A have a structure similar to a drop curtain, each hanging mechanism 9A can change the position of the lower end 20A of the baffle member 2A in the height direction D3 by moving the lower end of the corresponding baffle member 2A up and down.

[0161] In the first modification, the control system 100a includes a control device 4a as shown in FIG.

[0162] The control device 4a has a function to control a plurality of (five in the illustrated example) ventilation fans 52 as well as a function to control a plurality of hanging mechanisms 9A. More specifically, the control device 4a is configured to individually control the plurality of hanging mechanisms 9A. When changing the height of the lower end 20A (see FIG. 6) of each baffle member 2A, the control device 4a individually controls the plurality of hanging mechanisms 9A.

[0163] As described above, the control system 100a according to the first modification is provided with a hanging mechanism 9A that can move the baffle member 2A in the height direction D3 (see FIG. 6) of the building 6 (see FIG. 6). This allows the height of the baffle member 2A to be easily changed. In other words, the height from the floor surface 68 (see FIG. 6) of the building 6 to the lower end 20A of the baffle member 2A can be easily changed. As a result, the position of the baffle member 2A can be adjusted depending on the season, time, or temperature of the interior space (space 7) (see FIG. 6) of the building 6. For example, if livestock 9 are present in the interior space (space 7), the height of the baffle member 2A can be adjusted depending on the raising status of the livestock 9.

[0164] As a second modification of the second embodiment, the control system 100b may include an environmental facility (ventilation facility) 5b as shown in FIG. 9, instead of the environmental facility (ventilation facility) 5 (see FIG. 5).

[0165] The environmental equipment (ventilation equipment) 5b includes a plurality of (six in the illustrated example) ventilation fans 52b provided at the air intake port 66, instead of the plurality of ventilation fans 52 (see FIG. 5) provided at the exhaust port 67. The plurality of ventilation fans 52b are provided, for example, in the same number at each of the two air intake ports 66. More specifically, at the air intake port 661, ventilation fan 52b, ventilation fan 522b, and ventilation fan 523b are lined up in this order in the longitudinal direction D1. At the air intake port 662, ventilation fan 524b, ventilation fan 525b, and ventilation fan 526b are lined up in this order in the longitudinal direction D1. The plurality of ventilation fans 52b supply air from outside the building 6 to the interior space (space 7).

[0166] Moreover, the environmental equipment (ventilation equipment) 5b includes an opening / closing window 51b provided at the exhaust port 67 instead of the opening / closing window 51 provided at the air intake port 66 (see FIG. 5).

[0167] The control device 4b of the control system 100b according to the second modification has a function of controlling a plurality of ventilation fans 52b. More specifically, the control device 4b individually controls the plurality of ventilation fans 52b. Note that, regarding the control device 4b, a description of the same functions as those of the control device 4 of the second embodiment will be omitted.

[0168] In the control system 100b according to the second modification, a ventilation fan 52b that supplies air from outside the building 6 to the internal space (space 7) is provided in the air intake port 66. As a result, by drawing air in through the air intake port 66, the air in the internal space (space 7) can be exhausted so as to be pushed out through the exhaust port 67.

[0169] As a third modification of the second embodiment, the control system 100c may include an environmental facility (ventilation facility) 5c as shown in Fig. 10. The environmental facility (ventilation facility) 5c includes both a plurality of ventilation fans 52 provided at the exhaust port 67 and a plurality of ventilation fans 52b provided at the intake port 66.

[0170] A control device 4c of a control system 100c according to Modification 3 has a function of controlling a plurality of ventilation fans 52 and a plurality of ventilation fans 52b. More specifically, the control device 4c individually controls the plurality of ventilation fans 52 and the plurality of ventilation fans 52b. Note that, regarding the control device 4c, a description of the same functions as those of the control device 4 of Embodiment 2 will be omitted.

[0171] In the control system 100c according to the third modification, ventilation fans 52, 52b that supply air from outside the building 6 to the internal space (space 7) are provided at both the air inlet 66 and the air outlet 67. As a result, by drawing air in through the air inlet 66, the air in the internal space (space 7) can be exhausted by being pushed out through the air outlet 67, and by drawing air in through the air outlet 67, the air in the internal space (space 7) can be exhausted to the outside by being sucked in. As a result, the air intake and exhaust capacity can be improved.

[0172] As another modification of the second embodiment, the baffle member 2A is detachable from the building 6. This allows the baffle member 2A to be attached to or detached from the building 6 depending on the need for the baffle member 2A. For example, if livestock 9 are present in the interior space (space 7), the baffle member 2A can be attached to or detached from the building 6 depending on the breeding status of the livestock 9.

[0173] As another modification of the second embodiment, the baffle member 2A may be a flexible vinyl sheet.

[0174] The building 6 is not limited to a livestock barn, but may be a building where people reside. The building 6 may be, for example, a gymnasium in a school or the like. Generally, it is desirable to avoid constantly blowing wind on people. However, for example, when exercising in a gymnasium, it is preferable to install at least one baffle member 2A and adjust the air velocity to a desired velocity at any height (at the height of a person's head) in the interior space (space 7) of the building 6 to prevent heatstroke.

[0175] As another modification of the second embodiment, a mechanism may be provided to move each of the multiple baffle members 2A in the longitudinal direction D1 of the building 6. This makes it possible to easily change the spacing between adjacent baffle members 2A.

[0176] As another modification of the second embodiment, the air intake vent 66 may be provided in the second side wall 64 of the building 6, and the air exhaust vent 67 may be provided in the first side walls 62 and 63 of the building 6.

[0177] The control systems according to the above-described modifications also achieve the same effects as the control system 100 according to the second embodiment.

[0178] The above-described embodiments and modifications are merely a part of the various embodiments and modifications of the present invention. Furthermore, the embodiments and modifications can be modified in various ways depending on the design, etc., as long as the object of the present invention can be achieved.

The equipment control unit (13) controls environmental equipment (5; 5b; 5c) for controlling the environment of the space (7). The equipment control unit (13) uses the living body detection information to control the environmental equipment (5; 5b; 5c) so as to control the environment of an area where the livestock (9) actually exist.

[0191] According to the sensible temperature calculation system (1) of the sixth aspect, the environment can be controlled by giving priority to an area in the space (7) where livestock (9) actually exist over an area where livestock (9) do not exist, thereby enabling efficient environment control.

[0196] The sensible temperature calculation system (1) according to a ninth aspect is the system of any one of the first to eighth aspects, further including an abnormality detection unit (124) and a notification control unit (15). The abnormality detection unit (124) detects livestock (9) present in the space of an abnormal environment. When the abnormality detection unit (124) detects livestock (9) present in the space of an abnormal environment, the notification control unit (15) controls the notification device (21) to notify at least one of the livestock (9) present in the space of the abnormal environment and the position of the livestock (9) present in the space of the abnormal environment via the notification device (21).

[0197] According to the sensible temperature calculation system (1) of the ninth aspect, it is possible to promptly take measures for the livestock (9) existing in an abnormal environment space.

[0200] An environmental control system (2) according to an eleventh aspect includes the sensible temperature calculation system (1) according to any one of the first to tenth aspects, a measuring device (3), and environmental equipment (5; 5b; 5c). The measuring device (3) measures environmental information and outputs the environmental information to the sensible temperature calculation system (1). The environmental equipment (5; 5b; 5c) controls the environment of the space (7) based on the sensible temperature distribution.

[0201] According to the environmental control system (2) of the eleventh aspect, the sensible temperature calculation system (1) controls the environment of the space (7) in consideration of the sensible temperature distribution calculated by the first calculation unit (121), thereby making it possible to bring the actual sensible temperatures of the livestock (9) throughout the space (7) closer to a temperature suitable for the livestock (9).

[0202] A twelfth aspect of the present invention provides a method for calculating a sensible temperature, comprising a first calculation step and a second calculation step. In the first calculation step, an environmental distribution of the space (7) is calculated using environmental information representing the environment of the space (7) in which the livestock (9) are present. In the second calculation step, an sensible temperature distribution of the livestock (9) is calculated using the environmental distribution calculated in the first calculation step.

[0203] According to the sensible temperature calculation method of the twelfth aspect, the environment of the space (7) is controlled in consideration of the sensible temperature distribution calculated in the first calculation step, so that the actual sensible temperatures of the livestock (9) throughout the space (7) can be made closer to a temperature suitable for the livestock (9).

[0204] A program according to a thirteenth aspect is a program for causing one or more processors to execute the sensible temperature calculation method according to the twelfth aspect.

[0205] According to the program of the thirteenth aspect, the environment of the space (7) is controlled in consideration of the sensible temperature distribution calculated in the first calculation step, so that the actual sensible temperature of the livestock (9) throughout the space (7) can be made closer to a temperature suitable for the livestock (9).

[0207] According to the environmental control system (2) of the fourteenth aspect, the space (73) between the lower end (20A) of the baffle member (2A) and the floor surface (68) can be narrowed, and therefore the wind speed of the air passing through the space (73) can be increased. As a result, heat retained in the interior space (space 7) of the building (6) can be easily discharged to the outside of the building (6).

[0208] In the environmental control system (2) according to the fifteenth aspect, in the fourteenth aspect, the baffle member (2A) is arranged so as to reduce the difference in wind speed between positions in the region between the baffle member (2A) and the exhaust port (67) in the interior space (space 7) of the building (6).

[0216] In an environmental control system (2) according to a nineteenth aspect, in any one of the fourteenth to eighteenth aspects, the environmental equipment (5; 5b; 5c) includes a ventilation fan (52). The ventilation fan (52) is provided at the exhaust port (67) and exhausts air from the interior space (space 7) to the outside of the building (6).

[0217] According to the environmental control system (2) of the nineteenth aspect, air in the internal space (space 7) can be taken in on the exhaust side and exhausted to the outside of the building (6).

[0218] The environmental control system (2) according to the twentieth aspect is a nineteenth aspect, further including a control device (4; 4a; 4c). A plurality of ventilation fans (52) are provided. The control devices (4; 4a; 4c) receive an input of an outside air temperature outside the building (6). The higher the outside air temperature input to the control devices (4; 4a; 4c), the more ventilation fans (52) to operate among the plurality of ventilation fans (52). The lower the outside air temperature input to the control devices (4; 4a; 4c), the more ventilation fans (52) to operate among the plurality of ventilation fans (52).

[0219] According to the environmental control system (2) of the 20th aspect, even if the outside temperature outside the building (6) fluctuates, the air speed in the interior space (space 7) of the building (6) can be maintained within a desired speed range.

[0221] According to the environmental control system (2) of the twenty-first aspect, it is possible to reduce heat retention even in the interior space (space 7) of the livestock barn, thereby reducing stress on the livestock (9) caused by heat, and as a result, it is possible to provide a comfortable growing environment for the livestock (9).

[0222] The environmental control system (2) according to a 22nd aspect is any one of the 14th to 21st aspects, further comprising a hanging mechanism (9A). The hanging mechanism (9A) is capable of moving a lower end (20A) of the baffle member (2A) in a height direction (D3) of the building (6).

[0224] In the environmental control system (2) according to a 23rd aspect, in any one of the 14th to 22nd aspects, the baffle member (2A) is removable from the building (6).

[0225] According to the environmental control system (2) of the twenty-third aspect, the baffle member (2A) can be attached to or detached from the building (6) depending on the need for the baffle member (2A). For example, if livestock (9) are present in the interior space (space 7), the baffle member (2A) can be attached to or detached from the building (6) depending on the breeding status of the livestock (9).

[0226] A livestock barn (building 6) according to a 24th aspect includes the environmental control system (2) according to any one of the 14th to 23rd aspects and a building main body (61). A baffle member (2A) and environmental equipment (5; 5b; 5c) are attached to the building main body (61).

[0227] According to the livestock barn (building 6) of the 24th aspect, the control system (100; 100a; 100b; 100c) can narrow the space (73) between the lower end (20A) of the baffle member (2A) and the floor surface (68), thereby increasing the wind speed when air passes through the space (73). As a result, heat retained in the internal space (space 7) of the building (6) can be easily discharged to the outside of the building (6).

[0228] When the control system (100; 100a; 100b; 100c) is used in a barn for raising livestock (9), it can reduce stress on the livestock (9) caused by heat accumulating in the internal space (space 7). In particular, since chickens are covered entirely with feathers and do not have sweat glands, when the livestock (9) are chickens, it is important to expel heat accumulating in the internal space (space 7) to prevent the internal space (space 7) from becoming too hot.

[0229] A control method according to a 25th aspect is a control method for controlling the wind speed of air supplied through an air inlet (66) of a building (6) and exhausted through an exhaust outlet (67) of the building (6) to the outside of the building (6) through an internal space (space 7). In the control method, a baffle member (2A) is suspended from a ceiling (69) of the building (6) between the air inlet (66) and the exhaust outlet (67) in the internal space (space 7) so that a space is formed between a lower end (20A) of the baffle member (2A) and a floor surface (68) of the building (6).

[0230] According to the control method of the 25th aspect, the space 73 between the lower end 20A of the baffle member 2A and the floor surface 68 can be narrowed, thereby increasing the wind speed when the air passes through the space 73. As a result, heat retained in the interior space (space 7) of the building 6 can be easily discharged to the outside of the building 6.

[0231] A control system (100; 100a; 100b; 100c) according to a 26th aspect is used in conjunction with an environmental facility (5; 5b; 5c) that ventilates an interior space (space 7) of a building (6), and controls the wind speed of air supplied through an air supply port (66) of the building (6), which passes through the interior space (space 7) and is exhausted to the outside of the building (6) through an exhaust port (67) of the building (6). The control system (100; 100a; 100b; 100c) includes at least one baffle member (2A). The baffle member (2A) is disposed in the interior space (space 7) between the air supply port (66) and the exhaust port (67), and is suspended from the ceiling (69) of the building (6) so as to define a space (73) between its lower end (20A) and the floor (68) of the building (6).
