[0033] like Figures 1 to 7As shown, the present embodiment is an intelligent low-carbon and energy-saving piglet incubator based on photovoltaic power supply, including an incubator body 1, a box cover 2 is arranged on the top of the incubator body 1, the box cover 2 is movable over the incubator body 1, the box cover 2 seals the top of the incubator body 1, and an insulation board 3 is arranged at the bottom of the inner cavity of the incubator body 1, the insulation board 3 provides heating for the piglets, an entrance 4 is opened in the middle of the front side wall of the incubator body 1, and an infrared sensor 5 is installed on the front inner wall of the incubator body 1 above the entrance 4. The brand of the infrared sensor 5 is wweiguo, and the model is CDD-11N. The infrared sensor 5 detects the piglets passing through the entrance 4, so as to realize the intelligent heating of the heating zone 32 of the insulation board 3, and the side wall of the incubator body 1 is installed with a temperature controller 6 for intelligently controlling the temperature of the insulation board 3.

[0034] Specifically, a ventilation slot 21 is provided through the middle of the box cover 2, and the ventilation slot 21 is rectangular. The bottom of the ventilation slot 21 is connected to the inner cavity of the insulation box body 1, and an air inlet slot 22 is provided on the top of the ventilation slot 21. A ventilation fan 23 is installed inside the ventilation slot 21. There are two ventilation fans 23, and the blowing direction is toward the bottom of the ventilation slot 21, so as to accelerate the air circulation inside the insulation box body 1 and ventilate the inside of the insulation box body 1. A ventilation net 24 is installed on the inner wall of the ventilation slot 21 below the ventilation fan 23, and ultraviolet sterilization lamps 26 are embedded on both sides of the ventilation slot 21 at the bottom of the box cover 2. When turned on, the ultraviolet sterilization lamps 26 emit ultraviolet rays to irradiate and sterilize the inside of the insulation box body 1.

[0035] Furthermore, the ventilation net 24 is woven from steel wires to form a rectangular box shape with a hollow interior. Air flows through the mesh gaps of the ventilation net 24. The width of the ventilation net 24 is matched with the width of the inner wall of the ventilation slot 21. The ventilation net 24 is connected to the inner wall of the ventilation slot 21. The interior of the ventilation net 24 is filled with air freshener particles 25. The air freshener particles 25 are evenly distributed in the ventilation net 24. The air passing through the ventilation net 24 carries the smell of the air freshener particles 25 to deodorize the interior of the thermal insulation box body 1.

[0036] Furthermore, the box cover 2 is in the shape of a quadrangular pyramid, and grooves 27 are provided on the side walls around the box cover 2. The grooves 27 are in the shape of triangular prisms, and a photovoltaic bracket 28 is connected inside the groove 27. The photovoltaic assembly 29 is in the shape of a triangular frame, and the photovoltaic bracket 28 is fixed inside the groove 27. A photovoltaic assembly 29 is installed above the photovoltaic bracket 28. The photovoltaic assembly 29 is installed in the groove 27 through the photovoltaic bracket 28. An energy storage battery 210 is arranged inside the groove 27. The charging end of the energy storage battery is connected to the photovoltaic assembly 29 and the mains. According to the power demand of the incubator main body 1, when the power generation of the photovoltaic assembly 29 is greater than the power consumption of the incubator main body 1, the incubator main body 1 is charged. When power is required, the energy storage battery 210 supplies power to the incubator body 1. When the power generation of the photovoltaic module 29 is less than the power demand of the incubator body 1, the mains power is supplied. There are several sow farrowing beds in the farrowing house. The sow farrowing beds are divided into four rows according to the pregnancy cycle, namely the first cycle, the second cycle, the third cycle and the fourth cycle. Since the temperature required for the heating zone 32 by piglets of different ages is different, the power consumption of each row of sow farrowing beds is different. The power of each energy storage battery 210 in each row of sow farrowing beds is obtained, and each energy storage battery 210 is divided into different levels according to the preset power threshold.

[0037] When the power of the energy storage battery 210 is less than 30%, it is forced to charge. The charging method can be selected from the photovoltaic module 29 charging and the mains charging. When the power supply of the photovoltaic module 29 meets the power supply requirements, the photovoltaic module 29 charging is preferred;

[0038] When the power of the energy storage battery 210 reaches 50%, the photovoltaic module 29 charging mode is adopted to continue charging, and the mains power stops charging;

[0039] After 23:00 at night, peak-valley charging is adopted, that is, charging with city electricity, so that the power of the energy storage battery 210 reaches 80%.

[0040] Furthermore, the detection end of the infrared sensor 5 faces the entrance 4, and the infrared sensor 5 is electrically connected to the temperature controller 6 through the circuit. When the piglet enters the incubator body 1 from the entrance 4, the infrared sensor 5 detects the passing of the piglet and transmits a signal to the PID algorithm microcontroller 61. The PID algorithm microcontroller 61 controls the heating zone 32 to heat up, while the constant temperature zone 31 remains unchanged. When no piglet enters the incubator body 1 to rest, the constant temperature zone 31 and the heating zone 32 both maintain a constant temperature, thereby realizing intelligent heating of the insulation board 3.

[0041] Furthermore, a constant temperature zone 31 is provided in the middle of the insulation board 3, and heating zones 32 are provided on both sides of the constant temperature zone 31. The resting part of the edge of the insulation board 3 is divided into the heating zone 32, and the non-resting part is divided into the constant temperature zone 31. The heating zone 32 is used in conjunction with the constant temperature zone 31 to reduce the power consumption of the insulation board 3, so that the piglet incubator is more energy-efficient to use. Electric heating wires 33 are installed inside the constant temperature zone 31 and the heating zone 32. A temperature sensor 34 is connected to one end of the electric heating wire 33 in the heating zone 32. The electric heating wire 33 has a ring-shaped structure. The temperature sensor 34 and the electric heating wire 33 are placed at the same level. The temperature sensor 34 and the electric heating wire 33 are connected to the temperature controller 6. A hollow groove 35 is opened inside the insulation board 3.

[0042] Furthermore, there are two heating zones 32, which are symmetrically arranged relative to the constant temperature zone 31. The width of the piglet insulation board 3 is set to a, and the distance from the entrance 4 to the side a is set to b. A circle is drawn with a as the diameter and b as the radius. The area where the two circles intersect is the rest area, that is, heating zones 32 are formed on the left and right sides of the piglet insulation board 3. The piglet insulation board 3 is 100CM long and 55CM wide. The length of the entrance 4 is 20CM, and the entrance 4 is the biological center of the long side. It is calculated that the proportion of the heating zone 32 to the total area is 58%. Compared with the traditional fully heated insulation board 3, the purpose of reducing the heating zone 32 domain and reducing the power consumption of the insulation board 3 can be achieved.

[0043] Furthermore, the temperature sensor 34 and the electric heating wire 33 are electrically connected to the temperature controller 6 through the circuit. When the heating zone 32 is heated, the received thermal signal is converted into an electrical signal through the temperature sensor 34 and transmitted to the PID algorithm single chip computer 61 through the A / D converter 62. After the PID algorithm single chip computer 61 receives the signal and performs PID data calculation processing, it controls the output voltage of the thyristor rectifier to adjust the power of the electric heating wire 33, and adjusts the temperature of the heating zone 32 to the most suitable temperature for the growth of piglets, wherein the most suitable temperature for the growth of the abdomen of piglets is shown in the following table:

[0044] Age Optimal abdominal temperature 1 week 28～32℃ 2–4 weeks 24～32℃

[0045] The constant temperature zone 31 of the insulation board 3 is maintained at 24° C., and the temperature of the heating zone 32 is implemented according to the temperature in the above table, so as to realize intelligent adjustment of insulation according to the age of the piglets.

[0046] Furthermore, a phase change energy storage interlayer 36 is provided in the hollow groove 35. The phase change energy storage interlayer 36 is filled with a phase change energy storage material. The phase change energy storage material is sodium sulfate decahydrate. Sodium sulfate decahydrate is selected as the phase change material. Its phase change temperature is 32°C and its density is 1.46g / cm3. Sodium sulfate decahydrate is used to absorb and release an appropriate amount of heat energy to extend the insulation time of the insulation board 3 and increase the utilization rate of electric energy.

[0047] Furthermore, the temperature controller 6 includes a PID algorithm microcontroller 61 and an A / D converter 62. A display screen 63 is installed on the outer surface of the temperature controller 6. A matrix keyboard 64 is installed on the outer surface of the temperature controller 6 below the display screen 63. The matrix keyboard 64 and the display screen 63 are electrically connected to the PID algorithm microcontroller 61 through circuits. The display screen 63 is used to display the real-time temperature of the constant temperature zone 31 and the heating zone 32 on the insulation board 3. The matrix keyboard 64 is used to input the temperature of the heating zone 32 into the temperature controller 6 according to the age of the piglets.

[0048] The method of using the present embodiment is as follows: the user first places the incubator body 1 in the farrowing house, the incubator body 1 is connected to the mains power supply and the energy storage battery 210 on the box cover 2, the photovoltaic module 29 collects solar energy and converts it into electrical energy, the photovoltaic module 29 and the mains power charge the energy storage battery 210, when the incubator body 1 is started, the electric heating wire 33 in the insulation board 3 generates heat, the constant temperature zone 31 and the heating zone 32 both maintain a constant temperature of 24 degrees Celsius, when the piglets enter the incubator body 1 from the entrance 4, the infrared sensor 5 detects the piglets passing by, the infrared sensor 5 transmits a signal to the PID algorithm single chip computer 61, the PID algorithm single chip computer 61 controls the heating zone 32 to heat up, the temperature sensor 34 in the heating zone 32 converts the received thermal signal into an electrical signal, and transmits it to the PID algorithm single chip computer 6 through the A / D converter 62. 1, after the PID algorithm single-chip computer 61 receives the signal and performs PID data calculation processing, it controls the output voltage of the thyristor rectifier to adjust the power of the electric heating wire 33, and adjusts the temperature of the heating zone 32 to the most suitable temperature for the growth of piglets. At this time, the constant temperature zone 31 remains unchanged. After the incubator body 1 has been used for a period of time, in order to avoid the growth of bacteria in the incubator body 1, the incubator body 1 needs to be ventilated regularly. The ventilation fan 23 starts to drive the air circulation in the incubator body 1, and the external air is blown into the ventilation slot 21 from the air inlet slot 22, and enters the interior of the incubator body 1 after passing through the ventilation net 24. The air carries the smell of the air freshener particles 25 to cover the odor inside the incubator body 1, and ventilation and deodorization are carried out simultaneously, and the interior of the incubator body 1 is illuminated and sterilized by turning on the ultraviolet sterilization lamp 26.
