Description

[Technical field]

[0001] The present invention relates to a poultry house ventilation system and a method for controlling ventilation equipment. [Background technology]

[0002] Conventionally, in windowless chicken coops (also called sealed chicken coops) for laying hens, as shown in Patent Document 1, either positive pressure ventilation or negative pressure ventilation is performed.

[0003] However, as windowless poultry houses become larger, it is extremely difficult to ventilate the air inside uniformly. Specifically, in windowless poultry houses in which cages are arranged in a multi-layered structure, it is difficult to ventilate the air inside the poultry house uniformly everywhere, and in some cases, stagnant air may occur in some places.

[0004] In addition, windowless poultry houses are equipped with intake fans, exhaust fans, vents, and other ventilation equipment, but there are cases where sufficient ventilation cannot be achieved depending on the weather information outside the poultry house (especially wind direction and wind speed, etc.).

[0005] Furthermore, windowless chicken coops are equipped with a chicken manure discharge device for discharging chicken manure to the outside. Depending on the operating conditions of the chicken manure discharge device, there is a problem that air containing microorganisms and viruses from the chicken manure pile outside the chicken coop can flow into the chicken coop when negative pressure ventilation is performed.

[0006] [Patent Document 1] JP 2008-61632 A Summary of the Invention [Problem to be solved by the invention]

[0007] Therefore, the present invention has been made to solve the above problems, and an object of the present invention is to realize a comfortable environment inside a chicken house. [Means for solving the problem]

[0008] In other words, the chicken coop ventilation system of the present invention comprises a ventilation equipment installed in a chicken coop and a control device that controls the ventilation equipment, and the control device controls the ventilation equipment based on at least one of meteorological information for the area in which the chicken coop is located or the operating status of a chicken manure discharge device in the chicken coop.

[0009] This chicken coop ventilation system controls the ventilation equipment based on at least one of the weather information for the area where the chicken coop is located or the operating status of the chicken coop's chicken manure discharge device, so that a comfortable environment can be achieved inside the chicken coop. As a result, the location of air stagnation and swirling currents inside the chicken coop can be changed or eliminated, and dust, dirt, feathers, etc. can be prevented from gathering in a specific location inside the chicken coop. In addition, air containing microorganisms and viruses can be prevented from flowing into the chicken coop from the chicken manure pile-up area outside the chicken coop. This makes it possible to prevent infectious diseases such as parasites, microorganisms, and viruses from gathering in a specific location inside the chicken coop. Therefore, it is possible to reduce the possibility that parasites, microorganisms, and viruses will adversely affect the chicken coop, and to reduce the risk of chickens becoming infected with infectious diseases.

[0010] The meteorological information may include at least one parameter selected from the group consisting of weather, sunrise time, sunset time, sunshine hours, wind direction, wind speed, and precipitation. These parameters have a large impact on the environment inside the poultry house, and by controlling the ventilation equipment based on these parameters, a comfortable environment inside the poultry house can be achieved.

[0011] In addition to weather information and the operation status of the poultry manure discharge device, the location where the poultry house is built also affects the environment inside the poultry house. For example, the environment inside the poultry house can be greatly affected by the presence of a mountain to the east of the poultry house, the absence of anything to block the north wind, the west sun shining in, etc. For this reason, it is desirable for the control device to control the ventilation equipment based on at least one of the weather information for the area in which the chicken house is located or the operating status of the chicken manure discharge device in the chicken house, as well as the geographical conditions of the chicken house.

[0012] As a specific embodiment of controlling the ventilation equipment based on meteorological information, the operating status of the chicken manure discharge device, etc., it is desirable that the control device controls the ventilation equipment to switch between negative pressure ventilation and positive pressure ventilation.

[0013] Here, "negative pressure ventilation" refers to a ventilation method in which an exhaust fan is driven to exhaust air from inside the poultry house. In this case, outside air enters the poultry house through an air inlet (ventilation port) installed inside the poultry house. The amount of ventilation in this negative pressure ventilation is controlled by selecting the number of exhaust fans in operation, controlling the rotation speed of the exhaust fan, controlling the opening of the air inlet, selecting the air inlet to be opened, etc. "Positive pressure ventilation" is a ventilation method in which air is introduced into the poultry house by driving an intake fan. In this case, the air inside the poultry house is exhausted to the outside through an exhaust port (ventilation port) installed inside the poultry house. The ventilation volume of this positive pressure ventilation is controlled by selecting the number of intake fans in operation, controlling the rotation speed of the intake fan, controlling the opening degree of the exhaust port, selecting the exhaust port to be opened, etc.

[0014] For example, when the poultry manure discharge device is activated and the poultry manure outlet (the opening for discharging poultry manure to the outside) installed in the poultry house is open, the poultry manure outlet is connected to the poultry manure pile outside the poultry house. In this state, the control device controls the ventilation equipment to switch to positive pressure ventilation, normal pressure ventilation (a state in which the intake and exhaust air are balanced), or weak negative pressure ventilation. This reduces the inflow of microorganisms and viruses from the outside through the poultry manure outlet, and reduces the risk of the air inside the poultry house being contaminated by microorganisms, viruses, etc.

[0015] In order to increase the flexibility of ventilation within the poultry house, it is desirable that two or more types of ventilation equipment, either an intake fan, an exhaust fan, or a ventilation opening, be installed on the same wall.

[0016] In addition, in order to increase the flexibility of ventilation within the chicken house, it is desirable to provide a blower that can switch between intake and exhaust air as the ventilation equipment.

[0017] It is desirable that the chicken coop ventilation system of the present invention further includes an air quality sensor installed inside the chicken coop, and that the control device controls the ventilation equipment based on a sensor signal from the air quality sensor in addition to at least one of meteorological information for the area in which the chicken coop is located or the operating status of a chicken manure discharge device in the chicken coop.

[0018] Here, the air quality sensor measures the temperature and humidity inside the chicken coop, the concentration and amount of components in the air (e.g., carbon dioxide (CO2), oxygen (O2), etc.), or the amount of dust, mites, feathers, etc. in the air. Note that a wind direction sensor, wind speed sensor, wind volume sensor, etc. that measure wind conditions may be used instead of the air quality sensor.

[0019] In this way, by controlling the ventilation equipment based on the sensor signal of the air quality sensor, a more comfortable environment in the poultry house can be realized. In addition, by using the sensor signal of the air quality sensor, information on whether stagnation of air, swirling flow, etc. have been eliminated before and after a change in the ventilation operation of the ventilation equipment can be obtained in real time. For example, the degree of ventilation of air at the location where the air quality sensor is installed can be determined from the change over time in the sensor signal of the air quality sensor.

[0020] For example, if the carbon dioxide concentration (CO2 concentration) increases, it is known that ventilation is poor, and if the carbon dioxide concentration (CO2 concentration) decreases as a result of changing the control operation of the ventilation equipment, it is known that ventilation has been promoted. Furthermore, if the change in the control operation of the ventilation equipment results in a drop in temperature that is unsuitable for chicken survival, it is determined that there is too much ventilation (for example, determined from the differential coefficient), and a new control operation can be implemented. Furthermore, by utilizing the temporal changes in the sensor signals of various sensors, such as the rise and fall of carbon dioxide concentration (CO2 concentration), it is possible to quickly reach the optimal value.

[0021] Specific examples of the air quality sensor include a temperature sensor or a CO2 sensor, and instead of the air quality sensor, a wind direction sensor, a wind speed sensor, an air volume sensor, etc. By providing these air quality sensors, wind direction sensors, wind speed sensors, air volume sensors, etc. at multiple locations in the chicken coop, the degree of ventilation at multiple locations in the chicken coop can be determined.

[0022] Furthermore, the ventilation equipment control method of the present invention is a ventilation equipment control method for controlling ventilation equipment installed in a chicken coop, and is characterized in that the ventilation equipment is controlled based on at least one of meteorological information for the area in which the chicken coop is located or the operating status of a chicken manure discharge device in the chicken coop. Effect of the Invention

[0023] According to the present invention configured in this manner, the ventilation equipment is controlled based on at least one of the weather information for the area where the chicken coop is located or the operating status of the chicken coop's chicken manure discharge device, thereby creating a comfortable environment inside the chicken coop.

[0025] Hereinafter, one embodiment of a chicken house ventilation system according to the present invention will be described with reference to the drawings. In addition, in any of the drawings shown below, for the purpose of easy understanding, some parts are omitted or exaggerated in schematic form as appropriate. The same components are denoted by the same reference numerals and the description thereof is omitted as appropriate.

[0026] The chicken house ventilation system 100 of this embodiment provides ventilation for a chicken house 10 called a closed chicken house (windowless chicken house) for egg-laying hens.

[0027] Here, as shown in Figure 1, the chicken coop 10 is a roughly rectangular parallelepiped building surrounded by four walls 10a-10d, and inside is provided cage rows 20 in which a plurality of cages for housing chickens are arranged in one direction. Figure 1 shows an example in which a plurality of (here, three) cage rows 20 are provided. Each cage row 20 may also have a multi-layer structure in which a plurality of cages are stacked vertically.

[0028] 1 and 2, the chicken coop 10 is also provided with a chicken manure discharge device 30 that collects chicken manure from each cage row 20 and discharges it outside the chicken coop 10. This chicken manure discharge device 30 is provided below each cage row 20 and includes a chicken manure conveyor 31 that collects chicken manure dropping from multiple cages, and a chicken manure collecting conveyor 32 that receives chicken manure transported from the multiple chicken manure conveyors 31. The chicken manure collecting conveyor 32 discharges chicken manure to an external chicken manure pile 40 through a chicken manure discharge outlet 10H (an opening for discharging chicken manure to the outside) provided in the wall of the chicken coop 10. The chicken manure discharge outlet 10H is configured to be openable and closable by an opening and closing cover 50.

[0029] Specifically, as shown in Fig. 1, the poultry house ventilation system 100 includes a ventilation equipment 2 provided in a poultry house 10, and a ventilation equipment control unit 3 that controls the ventilation equipment 2. The ventilation equipment control unit 3 is a so-called computer including, for example, a CPU, a memory, an A / D-D / A converter, input / output means, communication devices, etc.

[0030] As shown in FIG. 1, the ventilation equipment 2 has one or more ventilation openings 21 that can be opened or closed and provided in a partition wall (any of walls 10a to 10d) that separates the inside and outside of the chicken coop 10, and one or more ventilation fans 22, such as intake fans or exhaust fans, provided in the partition wall (any of walls 10a to 10d) that separates the inside and outside of the chicken coop 10.

[0031] In this embodiment, the ventilation openings 21 are provided in the end side walls 10a, 10c perpendicular to the cage row 20 of the chicken house 10. When multiple ventilation openings 21 are provided, the positions at which the ventilation openings 21 are provided can be set appropriately, and for example, they may be arranged above and below the end side walls 10a, 10c, left and right, or diagonally. The ventilation openings 21 may also be provided in the girder side walls 10b, 10d along the cage row 20.

[0032] Moreover, the ventilation fan 22 of this embodiment is an exhaust fan 22a that exhausts air from the inside of the poultry house 10 to the outside, or an intake fan 22b that supplies air from the outside to the inside of the poultry house 10. Moreover, the ventilation fan 22 may be a blower 22c that can switch between intake and exhaust.

[0033] The ventilation fans 22 are provided on the end walls 10a, 10c perpendicular to the cage row 20 of the poultry house 10. When multiple ventilation fans 22 are provided, the positions at which the ventilation fans 22 are provided can be set appropriately, and for example, they may be provided above and below the end walls 10a, 10c, left and right, or diagonally. The ventilation fans 22 may also be provided on the girder side walls 10b, 10d along the cage row 20.

[0034] In this embodiment, two or more of the ventilation opening 21, the exhaust fan 22a, and the intake fan 22b are provided on the same wall. That is, in this embodiment, two or more of the ventilation opening 21, the exhaust fan 22a, the intake fan 22b, and the blower 22c are provided on the end walls 10a and 10c. When the blower 22c is used as the ventilation fan 22, the blower 22c functions not only as the exhaust fan 22a and the intake fan 22b but also as the ventilation opening 21.

[0035] An example of the arrangement of the ventilation equipment 2 (ventilation opening 21, exhaust fan 22a, intake fan 22b, and blower 22c) will be described below with reference to Figs. 3 and 4.

[0036] <Ventilation equipment 2 layout example 1> FIG. 3 shows an example of the arrangement of the ventilation openings 21 and exhaust fans 21a as the ventilation equipment 2. In this example, multiple ventilation openings 21 and multiple exhaust fans 22a are arranged on one end wall 10a, and multiple ventilation openings 21 and multiple exhaust fans 22a are arranged on the other end wall 10c. In this case, the ventilation openings 21 serve as air inlets, and a cooling pad may be provided on the ventilation openings 21. Also, in FIG. 3, multiple stirring fans 23 are provided for stirring air inside the chicken coop. In FIG. 3, the arrangement of the ventilation openings 21 and exhaust fans 22a on the two end walls 10a and 10c is the same, but they may be arranged differently from each other.

[0037] In this arrangement example, by operating the exhaust fan 22a of one end side wall 10a, air is taken in through the ventilation opening 21 of the other end side wall 10c, and an air flow occurs from the other end side wall 10c to one end side wall 10a (one-sided exhaust operation from the end side wall 10a side). Also, by operating the exhaust fan 22a of the other end side wall 10c, air is taken in through the ventilation opening 21 of the one end side wall 10a, and an air flow occurs from one end side wall 10a to the other end side wall 10c (one-sided exhaust operation from the end side wall 10c side). Furthermore, the exhaust fans 22a of both end side walls 10a, 10c can also be operated (double-sided exhaust operation).

[0038] In the above arrangement example, an intake fan 22b may be provided in addition to the exhaust fan 22a on at least one of the end walls 10a, 10c, or the intake fan 22b may be provided instead of the exhaust fan 22a. By providing the intake fan 22b in this way, it is possible to perform one-sided intake operation or two-sided intake operation.

[0039] <Ventilation equipment 2 layout example 2> FIG. 4 shows an example of the arrangement of the ventilation equipment 2 when an exhaust fan 22a and a blower 22c are used.

[0040] In this example, one or more exhaust fans 22a and one or more blowers 22c are arranged on one end wall 10a, and one or more exhaust fans 22a and one or more blowers 22c are arranged on the other end wall 10a, 10c. Here, as shown in FIG. 5, a shutter 24 may be provided on the outside of the exhaust fan 22a. Also, a cooling pad 25 and a shutter 26 may be provided on the outside of the blower 22c. In FIG. 4, the exhaust fans 22a and the blowers 22c are arranged in the same manner on the two end walls 10a, 10c, but they may be arranged differently from each other.

[0041] In the above-mentioned second arrangement example, the intake fan 22b may be provided in addition to the exhaust fan 22a on at least one of the end walls 10a, 10c, or the intake fan 22b may be provided instead of the exhaust fan 22a.

[0042] <Control contents of ventilation equipment control unit 3> The ventilation equipment control unit 3 controls the ventilation equipment 2 based on at least one of the weather information for the area where the chicken coop 10 is located or the operating status of the chicken manure discharge device 30 of the chicken coop 10, as shown in Fig. 6. Here, the weather information includes at least one parameter selected from the group consisting of weather, sunrise time, sunset time, sunshine hours, wind direction, wind speed, and precipitation. The ventilation equipment control unit 3 obtains the weather information via the Internet using a communication device, and obtains the operating status of the chicken manure discharge device from the control device of the chicken manure discharge device 30.

[0043] Specifically, the ventilation equipment control unit 3 controls the ventilation equipment 2 based on weather information and the operating status of the chicken manure discharge device 30 in the chicken coop 10, and adjusts negative pressure ventilation, positive pressure ventilation, switching between negative pressure ventilation and positive pressure ventilation, etc.

[0044] Here, the adjustment of negative pressure ventilation includes adjustment of the strength of negative pressure ventilation, adjustment of the airflow of the internal air in negative pressure ventilation, etc. These adjustments can be made by increasing or decreasing the number of exhaust fans 22a or blowers 22c in operation, selecting the exhaust fans 22a or blowers 22c to be operated, increasing or decreasing the rotation speed of the exhaust fans 22a or blowers 22c, increasing or decreasing the opening degree of the ventilation openings 21, selecting the ventilation openings 21 to be opened, etc.

[0045] Adjustment of the positive pressure ventilation includes adjustment of the strength of the positive pressure ventilation, adjustment of the airflow of the internal air in the positive pressure ventilation, etc. This can be done by increasing or decreasing the number of operating intake fans 22b or blowers 22c, selecting the operating intake fans 22b or blowers 22c, increasing or decreasing the rotation speed of intake fans 22b or blowers 22c, increasing or decreasing the opening degree of ventilation openings 21, selecting the ventilation openings 21 to be opened, etc.

[0046] Furthermore, switching between negative pressure ventilation and positive pressure ventilation can be achieved by reversing the magnitude relationship between the numbers of exhaust fans 22a and intake fans 22b in operation, reversing the rotation direction of blower 22c, or the like.

[0047] The ventilation equipment control unit 3 can also control the ventilation equipment 2 based on at least one of the weather information for the area where the poultry house 10 is located or the operating status of the poultry manure discharge device 30 in the poultry house 10, as well as the geographical conditions of the poultry house 10. Note that examples of the geographical conditions include information such as the presence of a mountain to the east of the poultry house 10, the absence of anything to block the north wind, and the strong western sun, and such information is input to the ventilation equipment control unit 3 by default.

[0048] Furthermore, the ventilation equipment control unit 3 can also control the ventilation equipment 2 based on a sensor signal from an air quality sensor 4 (see FIG. 1) installed inside the poultry house 10. Here, the air quality sensor 4 measures the temperature, humidity, and concentration or amount of air components (e.g., carbon dioxide (CO2), oxygen (O2), etc.) inside the poultry house 10, or the amount of dust, mites, feathers, etc. in the air. Note that instead of the air quality sensor 4, a wind direction sensor, wind speed sensor, wind volume sensor, etc. that measure wind conditions may be used.

[0049] As shown in Fig. 6, the ventilation equipment control unit 3 receives the above-mentioned weather information and the operating status of the chicken manure discharge device 30 of the chicken coop 10 (open / close state of the chicken manure discharge port 10H) as input signals, and outputs a control signal for controlling the ventilation equipment 2 to the ventilation equipment 2 together with the geographical conditions input by initial setting. The control signal is operation / stop or rotation speed of each of the intake fans 22b, each of the exhaust fans 22a, the blower 22c, etc. The control signal also includes the opening degree of the ventilation port 21 or, if the ventilation fan 22 is provided with shutters 24, 26, the opening / closing of the shutters 24, 26, etc. If the intake fan 22b is provided with a cooling pad 25, the control signal also includes start / stop of water supply to the cooling pad 25.

[0050] A specific example of control by the ventilation equipment control unit 3 will be described below. For example, when one end wall 10a is windward and the other end wall 10c is leeward, exhausting from the exhaust fan 22a installed on the windward end wall 10a is not efficient. In this case, exhausting from the exhaust fan 22a installed on the leeward end wall 10c is more efficient. That is, the ventilation equipment control unit 3 switches the operating exhaust fan 22a from the windward end wall 10a to the leeward end wall 10c, so as to match the airflow generated inside the poultry house 10 with the wind direction outside the poultry house. In this case, it is considered to control the rotation speed of the exhaust fan 22a installed on the leeward end wall 10c based on the wind speed, which is a weather condition.

[0051] In addition, when one end wall 10a is windward and the other end wall 10c is leeward, air cannot be efficiently taken in from the air intake fan 22b provided on the leeward end wall 10c. In this case, air can be efficiently taken in from the air intake fan 22b provided on the windward end wall 10a. In other words, the ventilation equipment control unit 3 switches the operating air intake fan 22b from the leeward end wall 10c to the windward end wall 10a, so that the airflow generated inside the poultry house 10 is aligned with the wind direction outside the poultry house. In this case, it is considered to control the rotation speed of the air intake fan 22b provided on the windward end wall 10a based on meteorological conditions such as wind speed.

[0052] Furthermore, while the poultry manure discharge device 30 is discharging the poultry manure (or while the poultry manure discharge outlet 10H is open), the ventilation equipment control unit 3 may switch from negative pressure ventilation to positive pressure ventilation using the intake fan 22b, and may also increase the intensity of the positive pressure ventilation to reduce the inflow of microorganisms and viruses from the outside through the poultry manure discharge outlet 10H of the poultry house 10.

[0053] In addition, the ventilation equipment control unit 3 performs various controls such as increasing the intensity of positive pressure ventilation or negative pressure ventilation when the weather is fine, increasing the intensity of positive pressure ventilation or negative pressure ventilation at sunrise, and decreasing the intensity of positive pressure ventilation or negative pressure ventilation at sunset. The ventilation equipment control unit 3 may also switch from positive pressure ventilation to negative pressure ventilation or from positive pressure ventilation to negative pressure ventilation based on meteorological information or a sensor signal from the air quality sensor 4.

[0054] <Effects of this embodiment> According to the chicken coop ventilation system 100 of this embodiment, the ventilation equipment 2 is controlled based on at least one of the weather information of the area where the chicken coop 10 is located or the operating status of the chicken manure discharge device 30 of the chicken coop, so that a comfortable environment in the chicken coop can be realized. As a result, the location of air stagnation and swirling flow inside the chicken coop 10 can be changed or eliminated, and dust, dirt, feathers, etc. can be prevented from gathering in a specific location inside the chicken coop. In addition, air containing microorganisms and viruses can be prevented from flowing into the chicken coop from the chicken manure accumulation area 40 outside the chicken coop. This makes it possible to prevent infectious diseases such as parasites, microorganisms, and viruses from gathering in a specific location inside the chicken coop. Therefore, it is possible to reduce the possibility that parasites, microorganisms, and viruses will adversely affect the chicken coop, and the risk of chickens being infected with infectious diseases can be reduced.

[0055] <Modified embodiment of the present invention> The present invention is not limited to the above-described embodiment.

[0056] The ventilation equipment control unit 3 may be configured to change the control of the ventilation equipment 2 based on the elapsed time to change the airflow, or may be configured to change the control of the ventilation equipment 2 to change the airflow based on the conditions within the chicken coop 10 (e.g., air quality, wind speed, wind direction, etc.) and their changes over time or amount of change, etc.

[0057] In addition, the ventilation equipment control unit 3 may be configured to change the control of the ventilation equipment 2 to change the air flow when the control of the ventilation equipment 2 related to the ventilation of the chicken coop 10 remains in the same state for a predetermined period of time, that is, based on the elapsed time.

[0058] The ventilation equipment control unit 3 may be configured to generate new control contents for the ventilation equipment control unit 3 using a machine learning model (AI model) and output a control command including the new control contents. This control command may include multiple patterns of control contents (e.g., control pattern 1 and control pattern 2, etc.). Here, the machine learning model is, for example, a model trained by machine learning using temporal changes in the sensor signals of the air quality sensors 4 before and after a change in the control contents as a learning data set, and is stored in advance in the memory of the ventilation equipment control unit 3. Note that the learning data set may include weather information, the operating status of the poultry manure discharge device 30, the geographical conditions of the poultry house, etc.

[0059] Furthermore, the present invention is not limited to sealed chicken coops (windowless chicken coops), but can also be applied to other types of chicken coops, such as semi-sealed chicken coops and open chicken coops that have walls with curtains that can be opened or closed automatically or manually, and in which ventilation equipment such as ventilation fans is controlled to equalize the temperature inside the coop.

[0060] Furthermore, the present invention is not limited to chicken houses, but can also be applied to other livestock or poultry houses.

[0061] Furthermore, the present invention is not limited to the above-described embodiment, and it goes without saying that various modifications are possible without departing from the spirit and scope of the present invention. [Explanation of symbols]
