Description

Technical Field

[0001] The present invention relates to the technical field of environmental control, and in particular to an individualized intelligent environmental control system for a dairy farm. Background Art

[0002] Dairy farms also need to maintain a certain temperature and humidity while maintaining air circulation. Within the optimal temperature range for cows, cows can maintain a constant body temperature through their own regulatory mechanisms, and their milk production, reproductive performance and health status remain stable. Once the temperature rises, the humidity increases, and the air flow rate decreases, the cows' body temperature increases, their breathing and pulse speed up, and their feed and milk intake decrease. In order to reduce the impact of heat stress on dairy cows, certain heatstroke prevention and cooling measures must be taken in dairy farms.

[0003] At present, the most widely used cooling measure in farms is to use a spray system for cooling. Due to the individual differences of dairy cows, within a certain temperature range, only some cows may experience heat stress, while other cows can produce milk normally. For this reason, spray equipment is installed in each area of ​​the dairy farm. When some cows have abnormal body temperature, targeted cooling is carried out on individual cows.

[0004] In the individualized spray cooling method, the spray equipment adjusts its spray angle to face individual cows. At different spray angles, the spray range of the spray equipment is different. If the spray range is large, the sprayed liquid will fall on the surrounding cows, resulting in poor cooling effect for the cows and cooling of other cows, affecting the overall milk production efficiency. Summary of the invention

[0005] To this end, the present invention provides an individualized intelligent environmental control system for dairy farms, which effectively solves the technical problem in the prior art that the spraying range is uncertain, resulting in the sprayed liquid falling on the surrounding cows, causing poor cooling effect on the cows and cooling of other cows, affecting the overall milk production efficiency.

[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] like Figure 2 , Figure 3 , Figure 4 As shown, the present invention provides an individualized intelligent environment control system for a dairy farm, including a slide rail 1 installed on the top of the dairy farm, and a plurality of spray devices 2 are movably installed on the slide rail 1.

[0055] In the present invention, in order to better adapt to the position of individual cows and improve the utilization rate of water, the spraying device 2 is set to a structure in which the spraying range and the spraying angle are adjustable. Specifically, Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Fig.11As shown, the spraying equipment 2 includes a slide 21 movably mounted on a slide rail, a rotating frame 22 is rotatably mounted at the bottom of the slide 21, a movable seat 23 is movably mounted in the rotating frame 22, a spray head 25 is fixedly mounted at the bottom of the movable seat 23 through a connecting shaft 24, a rotating shaft 26 is provided at the end of the rotating frame 22, and a rotating driving member 3 is connected to the end of the rotating shaft 26. The rotating driving member 3 can drive the rotating frame 22 to rotate through the rotating shaft 26 to adjust the spraying direction of the spray head 25.

[0056] A sliding groove seat 27 for the movable seat 23 to move is installed in the rotating frame 22, a power seat 49 is installed in the rotating frame 22, a slider 410 is slidably installed in the power seat 49, and the slider 410 moves on the power seat 49 and drives the movable seat 23 to move on the sliding groove seat 27 by pulling force;

[0057] A flow tube 5 is installed on the power seat 49, one end of the flow tube 5 is connected to a water inlet pipe 6, and the other end is connected to a water injection pipe 7, and the end of the water injection pipe 7 is connected to the sprinkler head 25;

[0058] Among them, the flow tube 5 can be extended and retracted, and a flow cross section is formed inside it. The size of the flow cross section changes with the extension and retraction of the flow tube 5. The flow tube 5 moves synchronously with the slider 410. The flow tube 5 extends and retracts under the movement of the slider 410 to synchronously adjust the size of the flow cross section.

[0059] In the present invention, after the spraying angle of the spray head is adjusted, the distance of the spray head relative to the individual cow is adjusted by driving the movable seat to move on the sliding groove seat. When the spray head is adjusted toward the individual cow, the spraying range of the spray head relative to the individual cow becomes smaller, so that the water at the spraying point acts on the individual cow in an all-round way, thereby enhancing the cooling effect of the spray.

[0060] In addition, when the distance of the sprinkler head is adjusted, the flow tube is simultaneously driven to expand and contract, so that the size of the flow cross-section changes accordingly. When the sprinkler head is adjusted toward the individual cow, the flow cross-section can be simultaneously reduced to reduce the water flow rate, thereby avoiding the problem of individual cows being irritated by the increased water pressure due to the shortening of the spraying distance, thereby improving the individual cows' adaptability to spraying.

[0061] To achieve automatic environmental control, such as Figure 1 As shown, the present invention also has structures such as an infrared acquisition module and a main controller.

[0062] The infrared acquisition modules are evenly distributed in different breeding areas in the dairy farm. The infrared acquisition modules are used to identify the individual numbers of the cows in the breeding areas and collect the temperature data of each individual cow.

[0063] The slide rail 1 covers above each breeding area of ​​the dairy farm, and the spraying equipment 2 is installed in each breeding area of ​​the dairy farm. The spraying equipment 2 can spray one of the individual cows in the breeding area to regulate the temperature of the individual cow.

[0064] Generally, 1 to 2 spraying devices 2 are installed in each breeding area. If the breeding area is large, more spraying devices 2 are needed.

[0065] The main controller is in communication connection with the infrared acquisition module, and the main controller can control one of the spraying devices 2 to start and perform individual cooling at a fixed point based on the temperature data of the individual cow.

[0066] Each cow is in motion in different breeding areas. In order to distinguish different individual cows, a collar is generally set on the cow's neck with a number marked on the collar. Different individual cows are identified through an infrared acquisition module. Specifically, the infrared acquisition module includes a far-infrared temperature sensor and an infrared sensing device. The far-infrared temperature sensor and the infrared sensing device are generally installed on the square tube of the yoke frame in the dairy farm. The infrared sensing device identifies the individual numbers of the cows in the breeding area, mainly the numbers on the collars. The far-infrared temperature sensor measures the surface temperature of each individual cow, and the measured individual cow temperature is transmitted to the main controller and the data is recorded and saved.

[0067] The measured temperature data of individual cows are compared with the individual temperature threshold set in the main controller. When the comparison exceeds the individual temperature threshold, the spraying device 2 is controlled to start individual cooling at a fixed point.

[0068] Specifically, the main controller is connected to the variable frequency water pump controller, and the variable water pump controller is connected to the variable frequency water pump;

[0069] The variable frequency water pump is connected to the filter and the water tank in sequence through a water supply pipeline. A drainage pipeline is connected to the water supply pipeline between the variable frequency water pump and the filter. The drainage pipeline is connected to several spray equipment 2 through a shunt pipeline 10. A solenoid valve is connected between the drainage pipeline and the shunt pipeline 10. A water meter is provided on the drainage pipeline. The end of the shunt pipeline is connected to a water inlet pipe 6 and is connected to the spray equipment 2. The main controller is connected to the solenoid valve, and the water flow is controlled by the solenoid valve.

[0070] In addition, a solenoid valve may also be installed at the water supply pipeline connected to the variable frequency water pump. The solenoid valve here controls the opening and closing of the water supply pipeline connected to the variable frequency water pump, thereby controlling the start-up of the corresponding spraying device 2.

[0071] The water supply pipeline is made of PPR pipe, and the diversion pipeline is a thin and soft plastic pipe that can be bent and contracted multiple times.

[0072] The water flows from the water tank into the filter, is filtered, and then enters the drainage pipeline, and reaches the corresponding spraying equipment 2 through the corresponding diversion pipeline 10. That is to say, when the temperature of individual cows in a certain breeding area is abnormal, it is necessary to open the corresponding solenoid valve in the breeding area, open the diversion water tank, and the water can reach the spraying equipment 2 in the corresponding breeding area to implement spray cooling.

[0073] In addition to the cooling method of fixed-point individual cooling, this system can also perform comprehensive cooling in practice. In addition to regulating the temperature in the dairy farm, the humidity in the dairy farm can also be regulated. Specifically, a temperature and humidity acquisition module and a variable frequency fan are provided in the dairy farm. The temperature and humidity acquisition module collects temperature and humidity data in the dairy farm. The temperature and humidity acquisition module includes a temperature sensor and a humidity sensor. The temperature sensor is used to collect temperature data in the dairy farm, and the humidity sensor is used to collect humidity data in the dairy farm. The temperature sensor and humidity sensor are generally installed on the pillars in the middle of the dairy farm.

[0074] The main controller is connected to the variable frequency fan, and the main controller controls the frequency of the variable frequency fan according to the temperature and humidity data.

[0075] Among them, several variable frequency fans are set up and can be placed in different breeding areas. The variable frequency fans distributed in different locations in the factory can also be opened and closed independently. The distribution of the variable frequency fans is adjusted accordingly according to the size and height of the dairy farm.

[0076] The corresponding temperature threshold and humidity threshold are set according to the actual situation in the dairy farm. When the real-time temperature data exceeds the temperature threshold, it is necessary to start the variable frequency fan and / or spray equipment 2 through the main controller or directly on the control panel to perform comprehensive cooling control. When the real-time humidity data exceeds the humidity threshold, the main controller is required to start the variable frequency fan to promote moisture volatilization.

[0077] The control strategy of the variable frequency fan can be a progressive opening, for example: when the temperature is >20℃ or the humidity is >10%, turn on 20% of the maximum speed of the variable frequency fan, and after both thresholds are reached, turn on 35% of the maximum speed of the variable frequency fan; when the temperature is >25℃ or the humidity is >15%, turn on 40% of the maximum speed of the variable frequency fan, and after both thresholds are reached, turn on 60% of the maximum speed of the variable frequency fan; when the temperature is >28℃ or the humidity is >20%, turn on 80% of the maximum speed of the variable frequency fan, and after both thresholds are reached, turn on 100% of the maximum speed of the variable frequency fan. The specific adjustment can be made according to the actual situation.

[0078] The above describes the environmental control methods for cooling down individual cows and adjusting the temperature and humidity of the entire dairy farm. The control process depends on the temperature threshold of the individual cow and the temperature threshold and humidity threshold in the dairy farm. In practice, the temperature of the individual cow takes precedence over the judgment conditions of the ambient temperature and humidity, and the cooling process for individual cows takes precedence over the overall cooling process of the dairy farm.

[0079] When it is detected that the temperature of an individual cow drops, the spraying equipment 2 and the variable frequency fan corresponding to the cow may be stopped.

[0080] In the present invention, the environment control system further comprises an input module, a display module, a first analog-to-digital conversion module, a second analog-to-digital conversion module, and a timing module.

[0081] The input module, the display module, the first analog-to-digital conversion module, the second analog-to-digital conversion module, and the timing module are all connected to the main controller;

[0082] The temperature and humidity acquisition module is connected to the main controller via the first analog-to-digital conversion module, and the far-infrared temperature sensor and the infrared sensing device are connected to the main controller via the second analog-to-digital conversion module.

[0083] The temperature data and humidity data collected by the temperature sensor and the humidity sensor are converted into digital signals by the first analog-to-digital conversion module. The converted digital signals are more convenient for subsequent data processing. After comparing the data, the main controller sends a control signal to control the spray equipment 2 and / or the variable frequency fan to start.

[0084] The temperature data of individual cows collected by the far-infrared temperature sensor is converted into digital signals by the second analog-to-digital conversion module. The infrared sensing device determines the individual cows and their position signals through the second analog-to-digital conversion module and transmits them to the main controller. The converted digital signals are processed, and the main controller sends a control signal after comparing the data to control the spraying equipment 2 and / or the variable frequency fan to start positioning and spraying the individual cows at the target position.

[0085] During operation, the operator sets the temperature conditions for the intelligent opening of the spray equipment 2 in the input module. The operator can set the spraying time of the spray equipment 2, the blowing time of the variable frequency fan, the number of spray cycles and the spraying time interval in detail. Some of the set data are displayed on the display module, and the timing module is used to close the corresponding spray equipment 2 after the set spray time is reached.

[0086] In practical applications, the spraying device 2 may use a 360° rotating spray head.

[0087] In the present invention, the spraying range of the spraying head 25 relative to the individual cow is adjusted by adjusting the relative distance between the spraying head 25 and the individual cow, so that the water at the spraying point acts on the individual cow in an all-round manner, thereby enhancing the cooling effect of the spraying.

[0088] In order to adjust the spraying direction of the spray head 25, the rotating frame 22 of the present invention can rotate, such as Figure 6 As shown, a mounting frame 28 is installed at the bottom of the slide 21, and the rotating frame 22 is rotatably mounted on the mounting frame 28 through the rotating shaft 26; the rotating driving member 3 includes a first driving motor 31 installed on the mounting frame 28; the driving end of the first driving motor 31 is connected to the rotating shaft 26.

[0089] The first driving motor 31 drives the rotating frame 22 to rotate relative to the mounting frame 28 through the rotating shaft 26 and rotates around the rotating shaft 26, thereby driving the spray head 25 to rotate synchronously and adjust its spraying direction.

[0090] In practical applications, such as Fig.13 As shown in the figure, the ellipsoid represents an individual cow, and the dotted line represents the spraying range of the sprinkler head. The spraying range of the sprinkler head 25 does not completely cover a certain individual cow. It is very likely that some water will pass over the individual cow and fall on the ground or spray on other individual cows, which will lead to low water resource utilization and affect other individual cows with normal body temperature. For this reason, the present invention sets a sprinkler head 25 that can adjust the relative position along the spraying direction. When the spraying range is too large, the distance between the sprinkler head 25 and the target individual cow is reduced, which will reduce the spraying range of the sprinkler head 25 to cover the target individual cow, reduce water resource waste, and improve water utilization.

[0091] Specifically, Figure 7 , Figure 8 , Fig. 9 and Fig.11 As shown, a mounting groove seat 41 is installed in the rotating frame 22, a column shaft 42 is rotatably arranged in the mounting groove seat 41, a first transmission wheel 43 and a second transmission wheel 44 are installed on the column shaft 42, a pulling belt 45 is wound on the first transmission wheel 43, and a connecting belt 46 is wound on the second transmission wheel 44;

[0092] One end of the pulling belt 45 is connected to the outer periphery of the first transmission wheel 43, one end of the connecting belt 46 is connected to the outer periphery of the second transmission wheel 44, and the other end is connected to the movable seat 23; the end of the sliding groove seat 27 close to the installation groove seat 41 is closed, and a through groove 47 for the connecting belt 46 to pass through is opened, and an extrusion spring 48 is connected between the inside of the sliding groove seat 27 and the movable seat 23;

[0093] The first transmission wheel 43 can be driven to rotate by pulling the end of the retractable pulling belt 45 , and the second transmission wheel 44 rotates synchronously and pulls the retractable connecting belt 46 , and at the same time drives the movable seat 23 to move on the sliding groove seat 27 .

[0094] Among them, the extrusion spring 48 is always in an extruded state. Under the elastic force of the extrusion spring 48, the movable seat 23 is always subjected to a downward extrusion force, and is also subjected to the pulling force of the connecting belt 46. When the connecting belt 46 moves upward, the movable seat 23 follows the upward movement. When the connecting belt 46 moves downward, the movable seat 23 also moves downward synchronously under the action of the extrusion force. The connecting belt 46 is always in a straightened state.

[0095] The belt surfaces of the pulling belt 45 and the connecting belt 46 are both in contact with the corresponding wheel surfaces. In order to prevent the connecting belt 46 from contacting the notch of the through groove 47, a support wheel can be further arranged in the rotating frame 22, which is located directly below the second transmission wheel 44. The connecting belt 46 extends downward through between the second transmission wheel 44 and the support wheel and connects to the movable seat 23. This can avoid interference between the connecting belt 46 and the notch to generate friction that prevents the movement of the connecting belt 46.

[0096] like Fig.10 As shown, a power seat 49 is installed in the rotating frame 22, a slider 410 is slidably installed in the power seat 49, the end of the pulling belt 45 is connected to the slider 410, a driving cylinder 411 is installed on the side of the slider 410, a push column 412 is connected to the driving end of the driving cylinder 411, and the push column 412 is connected to the slider 410.

[0097] The driving cylinder 411 drives the slider 410 to move on the power seat 49. Under the force of the extrusion spring 48, the connecting belt 46 is always subjected to a downward pulling force, and the second transmission wheel 44 also has a tendency to rotate clockwise under the pulling force of the connecting belt 46. When the slider 410 is stationary, the pulling belt 45 on the first transmission wheel 43 is subjected to a counterclockwise pulling force, and the second transmission wheel 44 is subjected to a clockwise pulling force. Under the pulling forces in different directions, the first transmission wheel 43 and the second transmission wheel 44 remain stationary, and when the slider 410 moves close to the side of the first transmission wheel 43, the first transmission wheel 43 and the second transmission wheel 44 rotate clockwise under the pulling force of the connecting belt 46, so that the movable seat 23 can move downward along the sliding groove seat 27 for a distance, driving the spray head 25 to move forward for a distance in the spraying direction. After adjustment, the spraying range of the spray head 25 completely covers the individual cows.

[0098] In practical applications, when the sprinkler head 25 is close to the individual cow, the water impact force on the body surface of the individual cow will also increase. If the water pressure change increases significantly, the cow will be stimulated and avoid it, which will result in the failure of cooling. In this regard, the present invention makes the following design, such as Fig.12As shown, the flow tube 5 includes a main tube 51 and a movable tube 52, a water inlet pipe 6 is connected to the movable tube 52, and a water injection pipe 7 is connected to the main tube 51;

[0099] A connecting cylinder 53 is installed in the main cylinder 51, and the end of the movable cylinder 52 is movably arranged in the connecting cylinder 53, and the outer wall of the movable cylinder 52 fits with the inner wall of the connecting cylinder 53;

[0100] A first water-passing long hole 54 is formed on the inner wall of the connecting cylinder 53, and a second water-passing long hole 55 is formed on the inner wall of the movable cylinder 52. The second water-passing long hole 55 and the first water-passing long hole 54 form a flow cross section. Water enters the movable cylinder 52 through the water inlet pipe 6, passes through the second water-passing long hole 55 and the first water-passing long hole 54, enters the main cylinder 51, and is then discharged to the sprinkler head 25 through the water injection pipe 7.

[0101] The movable cylinder 52 is externally connected to a connecting plate 56 , and the end of the connecting plate 56 is connected to a push column 412 . The push column 412 drives the movable cylinder 52 to move and adjust the relative position of the movable cylinder 52 in the connecting cylinder 53 to adjust the connecting cross section between the second water-passing long hole 55 and the first water-passing long hole 54 .

[0102] When the driving cylinder 411 pushes the slider 410 to move toward the first transmission wheel 43, it also drives the connecting plate 56 to move toward the first transmission wheel 43, and synchronously drives the movable cylinder 52 to move into the connecting cylinder 53. In the initial state, the second water-passing long hole 55 and the first water-passing long hole 54 overlap, and the connecting cross-section between the second water-passing long hole 55 and the first water-passing long hole 54 is the largest. After the movement, the connecting cross-section between the second water-passing long hole 55 and the first water-passing long hole 54 becomes smaller, and the water flow rate passing between the second water-passing long hole 55 and the first water-passing long hole 54 per unit time becomes smaller, which makes the water volume at the sprinkler head 25 smaller and the water pressure lower.

[0103] Therefore, when the spray head 25 approaches an individual cow along its own spraying direction, the spraying volume is reduced, which can avoid the impact of excessive water pressure on the individual cow, prevent the individual cow from being frightened and avoiding, and improve the spraying adaptability of the individual cow.

[0104] In the present invention, the spray head 25 in the breeding area can be adjusted in not only the spraying direction, but also the position thereof. Figure 4 As shown, a second drive motor 8 is installed on the slide 21, a gear 9 is connected to the driving end of the second drive motor 8, a rack is provided at the bottom of the slide rail 1, and the gear 9 is meshed with the rack;

[0105] The second driving motor 8 drives the gear 9 to rotate, so as to drive the gear 9 and the rack to move relative to each other, so that the gear 9 and the slide 21 move relative to the rack.

[0106] The slide seat 21 can move the spray head 25 along the direction of the slide rail 1, so that the spray head 25 adjusts the spraying position, so as to implement the spraying action on individual cows at various positions in the breeding area.

[0107] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
