[0038] Figure 1 Schematic diagram of the structure of the intelligent adjustment system for building pig farm environment based on edge-cloud collaboration provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0039] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] It should be understood that the embodiments described are only a portion 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 persons of ordinary skill in the art without creative work are within the scope of protection of the present invention.

[0041] Figure 1 This is a schematic diagram of the structure of the intelligent pig farm environment adjustment system based on edge-cloud collaboration provided by an embodiment of the present invention. Figure 1 , the system comprises:

[0042] Lighting equipment 3, used to provide lighting inside the pig farm;

[0043] At least one light sensor 1, arranged at a designated location in the pig farm, for sensing and measuring the current light value in the pig farm;

[0044] The controller 2 is connected to the output end of the light sensor 1 and is also connected to the control end of the lighting device 3. The controller 2 is used to determine whether the current light value in the pig farm is within the preset light range, and when the current light value in the pig farm is not within the preset light range, control and adjust the output light of the lighting device 3 to make the light value in the pig farm meet the requirements.

[0045] The beneficial effects of the above technical solution are as follows: first, the current light level within the pig farm is sensed and measured by light sensor 1. Then, if this light level is not within a preset light range, the output of lighting device 3 is automatically controlled and adjusted to ensure that the light level within the pig farm meets the required level. This invention can intelligently and automatically adjust the lighting conditions within the pig farm, reducing manpower and material resources, and effectively improving the average daily feed intake, average daily weight gain, exercise volume, and feed conversion rate of pigs, thereby promoting the healthy and rapid growth of pigs.

[0046] As an optional embodiment, the said building pig farm environment intelligent adjustment system based on edge-cloud collaboration further includes: air conditioning;

[0047] At least one temperature sensor is provided in the pig farm and is used to measure the current temperature in the pig farm in real time;

[0048] The controller 2 is also connected to the output end of the temperature sensor. The controller 2 is also used to determine whether the current temperature in the pig farm is within the preset temperature range, and when the current temperature in the pig farm is not within the preset temperature range, control and adjust the air conditioner so that the temperature in the pig farm meets the requirements.

[0049] The beneficial effects of the above technical solution are as follows: temperature is one of the factors affecting the healthy growth of pigs. The optimal growth rate of fattening pigs is around 20°C, while the optimal feed utilization rate is 25°C. The further the ambient temperature is from the optimal temperature for pigs, the greater the impact on production performance. A temperature sensor measures the current temperature in the pig farm in real time. If the current temperature is not within the preset temperature range, the air conditioning is controlled and adjusted to ensure that the temperature in the pig farm meets the required requirements. This achieves the goal of automatically controlling the temperature in the pig farm, improving production efficiency and promoting the healthy growth of pigs.

[0050] As an optional embodiment, the intelligent environmental adjustment system for building pig farms based on edge-cloud collaboration further includes:

[0051] A humidifier and dehumidifier is installed in the pig farm and is used to humidify or dehumidify the air in the pig farm;

[0052] At least one humidity sensor is provided in the pig farm and is used to measure the current humidity in the pig farm in real time;

[0053] The controller 2 is also connected to the output end of the humidity sensor. The controller 2 is also used to determine whether the current humidity in the pig farm is within the preset humidity range, and when the current humidity in the pig farm is not within the preset humidity range, control and adjust the humidifier and dehumidifier to humidify or dehumidify the air in the pig farm so that the humidity in the pig farm meets the requirements.

[0054] The beneficial effects of the above technical solution are as follows: air humidity has a significant impact on pig growth. Improper air humidity in piggeries can lead to various diseases, seriously affecting pig growth. A humidity sensor measures the current humidity in the pig farm in real time. If the current humidity is not within a preset range, the humidifier / dehumidifier is controlled to humidify or dehumidify the air in the pig farm to ensure that the humidity meets the required level. This achieves the goal of automatically controlling the humidity in the pig farm, improves production efficiency, and promotes the healthy growth of pigs.

[0055] As an optional embodiment, the intelligent environmental adjustment system for building pig farms based on edge-cloud collaboration further includes:

[0056] A track is provided on the roof of the pig farm, and the track is in a spiral shape;

[0057] A mounting seat, the upper surface of which has a slider sleeved on the track, and the lighting device 3 is connected to the lower surface of the mounting seat;

[0058] The driving mechanism is connected to the slider and the controller 2 and is used to drive the slider to slide on the track under the control of the controller 2 to adjust the position of the lighting equipment 3 on the roof inside the pig farm.

[0059] The beneficial effect of the above technical solution is that the position of the light can be adjusted by sliding the lighting device 3 on the preset roof rail, which has the advantages of easy implementation and good dimming effect.

[0060] As an optional embodiment, the intelligent environmental adjustment system for building pig farms based on edge-cloud collaboration further includes:

[0061] A camera device is installed at the center of the roof inside the pig farm, and is used to capture images of the internal environment of the pig farm;

[0062] The controller 2 is also used to identify the pigs in the image of the internal environment of the pig farm taken by the camera equipment, and determine the optimal illumination position of the lighting equipment 3 on the roof inside the pig farm based on the distribution of the pigs in the image of the internal environment of the pig farm, and control the driving mechanism to drive the slider to move on the track to adjust the position of the lighting equipment 3 to the optimal illumination position.

[0063] The above technical solution has the following beneficial effects: Pigs in a pig farm are often in motion, and timely adjustment of the lighting position is necessary to achieve optimal lighting effects. By collecting real-time images of the pig farm's internal environment and using image recognition technology to determine the distribution of pigs, the position of the lighting device 3 is adjusted to the optimal illumination position based on the pig distribution. This optimizes the lighting environment around the pigs, while achieving maximum lighting effects with minimal equipment, effectively reducing the cost of deploying lighting equipment and reducing energy consumption.

[0064] As an optional embodiment, the lighting device is connected to the mounting base via a controllable universal joint;

[0065] The controller 2 is also used to determine the optimal tilt angle of the lighting equipment 3 based on the optimal illumination position of the lighting equipment 3 on the roof inside the pig farm and the distribution of pigs in the internal environment image of the pig farm, and to adjust the tilt angle of the lighting equipment 3 at the optimal illumination position to the optimal tilt angle by controlling the rotation of the controllable universal joint.

[0066] The beneficial effect of the above technical solution is that the optimal tilt angle of the universal joint for tilting the lighting equipment 3 can be obtained according to the optimal illumination position of the lighting equipment 3 on the roof and the distribution of pigs in the building pig farm environment, so as to illuminate the pigs in the environment to the maximum extent and ensure the comprehensiveness of the lighting illumination.

[0067] As an optional embodiment, the controller 2 is further used to control the lighting equipment 3 to rotate in an inclined spiral manner according to the distribution of pigs in the internal environment image of the pig farm; wherein, the inclined spiral rotation takes the optimal inclination angle of the lighting equipment 3 as the initial angle, and reduces the inclination angle by 0.5° for each rotation until the inclination angle of the lighting equipment 3 is less than 0.5°, and then continues to rotate and increases by 0.5° for each rotation until the inclination angle of the lighting equipment 3 reaches the optimal inclination angle, and then repeats the above rotation process.

[0068] The beneficial effect of the above technical solution is that by controlling the lighting device 3 to rotate in an inclined spiral, pigs that are not illuminated due to mutual obstruction can also be illuminated, thereby ensuring that each pig can obtain good lighting.

[0069] As an optional embodiment, the controller 2 is specifically configured to determine the optimal illumination position of the lighting device 3 on the roof inside the pig farm according to the first formula, determine the optimal tilt angle of the lighting device 3 according to the second formula, and further specifically determine the rotation speed of the lighting device 3 performing the tilted spiral rotation according to the third formula;

[0070] Among them, the first formula is:

[0071]

[0072] Wherein, (I, J) represents the position point on the roof opposite to the environmental position corresponding to the pixel point in the ith row and the jth column in the internal environment image of the pig farm, and this position point is the optimal illumination position of the lighting equipment on the roof inside the pig farm; i represents the ith row in the internal environment image of the pig farm; j represents the jth column in the internal environment image of the pig farm; n represents the number of pixels in each column in the internal environment image of the pig farm; m represents the number of pixels in each row in the internal environment image of the pig farm; D(i) represents the number of pixels in the ith row of the internal environment image of the pig farm that are identified as pigs; D(j) represents the number of pixels in the jth column of the internal environment image of the pig farm that are identified as pigs;

[0073] The second formula is:

[0074]

[0075] Wherein, θ represents the optimal tilt angle of the lighting device; [a(e), b(e)] represents the position of the e-th pixel identified as a pig in the pig farm internal environment image, which is in the a(e)th row and the b(e)th column; K represents the scaling ratio of the pig farm internal environment image to the actual environment. For example, if the actual length of the pig farm is 5m and the pig farm length in the pig farm internal environment image is 5cm, then H represents the indoor height of the pig farm; Indicates that the value of e is changed from 1 to Get the maximum value in the brackets;

[0076] The third formula is:

[0077]

[0078] Wherein, ω represents the rotation speed of the lighting device performing the inclined spiral rotation; ω M Indicates the maximum preset rotation speed of the lighting device for tilted spiral rotation.

[0079] The beneficial effects of the above technical solution are as follows: the first formula (1) is used to determine the optimal irradiation position of the lighting device 3 on the roof according to the distribution of pigs in the building pig farm environment, and then the lighting device is moved to the position where the pigs in the room are relatively gathered for irradiation, which can improve the irradiation efficiency and reduce unnecessary energy loss; then the second formula (2) is used to obtain the optimal tilt angle of the universal joint to tilt the lighting device 3 according to the optimal irradiation position of the lighting device 3 on the roof and the distribution of pigs in the building pig farm environment, so as to illuminate the pigs in the environment to the maximum extent and ensure the comprehensiveness of the lighting illumination; finally, the third formula (3) is used to control the rotation speed of the lighting device 3 for tilting according to the distribution of pigs in the building pig farm environment, thereby controlling the irradiation speed according to the dispersion and aggregation of pigs in the pig farm environment, so as to reduce the time when the pigs are not illuminated during the tilt spiral rotation process and improve the system efficiency.

[0080] As can be seen from the contents of the above embodiments, by pre-setting the light sensor / temperature sensor / humidity sensor to collect the current light value / current temperature / current humidity in the pig farm in real time, and when the current light value / current temperature / current humidity is not within the preset humidity range, the lighting equipment / air conditioner / humidifier / dehumidifier is controlled to output light / temperature adjustment / humidification or dehumidification to the pig farm, so that the environmental parameters in the pig farm meet the requirements. Furthermore, according to the distribution of pigs in the building pig farm environment, the optimal illumination position of the lighting equipment on the roof, the optimal tilt angle and the rotation speed of the tilt rotation can be gradually determined, and then the lighting equipment can be controlled to operate according to these determined values, so that the pigs in the building pig farm environment can be fully illuminated by the light.
