The following describes the control method of the air conditioner in the hatching chamber with reference to a specific embodiment, however, it should be noted that the specific embodiment is only for better describing the present application and is not to be construed as an undue limitation on the present application. The same or corresponding terms as those of the above-described embodiments are explained, and the description of the present embodiment is omitted.
Referring to fig. 2, an ambient temperature collection module 11, an ambient humidity collection module 12 and a gas collection module 13 are disposed in the hatching chamber. The ambient temperature acquisition module 11 is used for monitoring the temperature in the hatching chamber in real time. The environment humidity acquisition module 12 is used for monitoring the humidity in the hatching chamber in real time. The gas collection module 13 is used for monitoring the gas concentration (e.g. oxygen concentration, carbon dioxide concentration) in the hatching chamber in real time.
At least one layer of egg rack is arranged in the hatching chamber and used for placing the eggs. The egg rack can be made of alloy and other heat exchange materials. The bottom of each layer of egg rack is provided with a refrigerant pipeline, and the refrigerant pipeline is correspondingly provided with a valve to control the on-off of the refrigerant pipeline. The bottom of the egg body is provided with a local temperature sensing module 14 for monitoring the temperature of the bottom of the egg body in real time.
The ambient temperature acquisition module 11, the ambient humidity acquisition module 12, the gas acquisition module 13 and the local temperature sensing module 14 transmit acquired data to the air conditioner controller 16 through the signal conversion circuit 15. For example, when the bottom of the egg body generates local heat, the local temperature sensing module 14 feeds back to the air conditioner controller 16, and it can determine that the egg body is a developing egg body and is a healthy egg.
The memory 17 is used for storing parameter requirement value ranges corresponding to all incubation phases, and comprises: a temperature demand range, a humidity demand range, and a gas concentration demand range.
The timer 18 is used to record the length of time that the eggs are in the hatching chamber, and the current hatching period can be determined by comparing the recorded length of time with the entire hatching period.
The air conditioner controller 16 is used for processing data fed back by other modules and calling data in the memory 17 for comparison, and controlling the air conditioner to adjust the temperature and the humidity in the hatching chamber and exchange fresh air for the hatching chamber, so that the optimal environment required by each hatching stage is accurately achieved. The air conditioner controller 16 is also used for delivering cold energy to the refrigerant pipeline at the bottom of the egg rack so as to realize the local cooling of the healthy eggs.
The following takes the incubation of eggs as an example, and the environmental parameter adjustment, the egg screening and the egg body local cooling during the incubation process will be described.
The method is characterized in that the shell breaking of chicks is finished, the hatching period of eggs is 21 days totally, according to different stages in the hatching process, the hatching period is divided into a hatching initial period, a hatching middle period and a hatching later period, the hatching period is respectively 1< -t 1 > to 6,7< -t 2 > to 14, and 15< -t 3 > to 21, and the unit is day (d). The temperature demand value range, humidity demand value range and gas concentration demand value range corresponding to each incubation period are set for the optimum environment required for each incubation period, respectively, and stored in the memory 17.
The air conditioner controller 16 timely calls the relevant data in the memory 17 according to the time provided by the timer 18, and compares the relevant data with the data fed back by the ambient temperature acquisition module 11, the ambient humidity acquisition module 12 and the gas acquisition module 13. And when any one of the current temperature, the current humidity and the current gas concentration in the hatching chamber does not meet the corresponding required value range in the memory 17, controlling the air conditioner to start adjusting the corresponding environmental parameter. And when the current temperature, the current humidity and the current gas concentration in the hatching chamber are all in accordance with the corresponding required value ranges in the memory 17, controlling the air conditioner to keep running at the current state.
The parameter requirement value range of the environmental parameters of each hatching stage is set as follows:
(1) Relative humidity
In the early stage of hatching, the relative humidity in the hatching chamber needs to be controlled to be about 60%. In the middle stage of hatching, the relative humidity in the hatching chamber needs to be controlled at 50% -55%. In the late stage of hatching, the relative humidity in the hatching chamber needs to be controlled at 65-70%.
The humidity is too high, so that the evaporation and the elimination of allantoic fluid of chick embryos are hindered, chick belly skin is easily caused, chick body tissues and yolk contain much water, and the body is heavy and dull; too low humidity causes excessive evaporation of water in the eggs, the chicks are dry and thin, the muscles are not plump, the feathers are too compact, and the individual is small, so that the control of proper humidity is necessary. Metabolism in the process of embryo development can not be separated from boiling water, but the internal water content of the egg is sufficient, and the egg shell, the shell membrane and the allantoic vessel have structures for preventing water from evaporating, so that the humidity requirement of the egg in the process of artificial incubation is not as strict as the temperature requirement, namely the application range of the chick embryo to the humidity is wider.
(2) Ambient temperature
In the early stage of hatching, the temperature in the hatching chamber needs to be controlled to be about 38.5 ℃. In the middle stage of hatching, the temperature in the hatching chamber needs to be controlled to be about 38 ℃. In the late stage of incubation, the temperature in the incubation chamber needs to be controlled at 37.9 ℃ in 15 days, and the temperature in the incubation chamber needs to be controlled at 37.3-37.5 ℃ in 16-21 days.
The egg hatching needs a certain temperature, the hatching temperature is about 37.5-38.5 ℃, and the temperature needs to be consistent with the hatching temperature of the hens, so that the requirement on the hatching temperature is strict, the embryo development is fast due to overheating, the embryo is dead due to incomplete development, the embryo development is easy to stop due to low temperature, and the chick development malformation or the embryo freeze death can be caused. Meanwhile, the self-temperature capability is very strong after the hatching eggs develop for 19 days, and the temperature detection and control in the period are very important.
(3) Concentration of gas
In the process of egg hatching, from blastoderm development, embryonic shield formation, to the development of original heart, yolk sac blood vessel and allantois, and finally the formation of embryo shell, three breathing modes exist: yolk sac respiration, allantoic respiration and lung respiration, wherein in the first stage of allantoic development in 4-8 days, embryo is converted from yolk sac respiration to allantoic respiration, and the allantoic respiration is converted into lung respiration in the 20 th day, and the three respiration modes have great difference on oxygen demand.
In the whole hatching process of eggs, enough oxygen is required to be kept, the oxygen content cannot be lower than 20%, the carbon dioxide cannot exceed 1%, and abnormal embryos can be generated due to excessive carbon dioxide, so that the hatching rate is low. The embryo at the initial stage of hatching has low demand for oxygen due to low metabolism of substances; in the middle stage, the respiration rate gradually increases along with the development of the embryo; on the last two days, the embryos started to breathe with the lungs, and oxygen consumption and carbon dioxide also increased dramatically. In the hatching chamber, along with the change of the demand of the eggs on oxygen, the oxygen concentration and the carbon dioxide concentration in the hatching chamber are changed, and fresh air is required to be changed to ensure that the gas concentration in the hatching chamber at each hatching stage is kept at the oxygen content which cannot be lower than 20 percent and the carbon dioxide which cannot exceed 1 percent.

And S308, the temperature of the bottom of the egg body meets the requirement.
And S309, opening a valve body of the four-way valve according to an instruction, and controlling the air conditioner to operate according to an actual control requirement.
