Detailed Description
In the live pig breeding industry, in order to ensure the comfort of a swinery and reduce the sick probability of the swinery, breeding enterprises pay more and more attention to the control of the pigsty environment. In order to improve the controllability of the pigsty environment, the pigsty is gradually changed from a traditional open pigsty to a closed pigsty, and the internal environment and the external environment of the pigsty are communicated only through the ventilation window. The control of the pigsty environment mainly comprises the control of the temperature and the humidity in the pigsty.
For the swinery, the swinery belongs to a heating source and can continuously emit heat outwards. The ventilation system in the pigsty is not only used as ventilation equipment for supplying oxygen to the interior of the pigsty, but also used as heat dissipation equipment for taking away heat in the pigsty to a certain extent. In addition, the herds are better for survival in humid environments, and therefore, in addition to ventilation systems, water spray equipment is often required in the pigsty.
The control and regulation of the temperature and the humidity of the pigsty are usually realized by regulating and controlling a ventilation system and water spraying equipment. At present, relatively more modes are adopted for controlling and adjusting the temperature and the humidity of the pigsty, for example, in order to cool the pigsty, air introduced into a ventilation system is cooled, or the air introduced into the ventilation system needs to pass through a water curtain and the like; water is sprayed into the pigsty to increase the humidity in the pigsty, and the like. For a conventional temperature and humidity control mode, the temperature reduction effect is poor, the water consumption is large, and the economic cost is high.
Therefore, the technical scheme that the temperature and humidity control effect is good and the water consumption can be reduced to a certain degree is provided.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, fig. 1 is a schematic flow chart of a method for controlling temperature and humidity in a pigsty provided in an embodiment of the present application, and the method may include:
s11: and respectively controlling the ventilation of the negative pressure ventilation system and the water spraying of the spraying system according to the set initial ventilation quantity and initial water spraying quantity.
At the initial control moment of the temperature and the humidity of the pigsty, the ventilation of the negative pressure ventilation system and the water spraying of the spraying system can be respectively controlled according to the set initial ventilation quantity and the initial water spraying quantity.
The initial ventilation amount and the initial water spraying amount may be based on factors such as the temperature of the outdoor environment at the initial time, the current season, the weight of the pigsty, etc., and may also be based on historical statistics according to experience setting of the operator, which is not limited in this application.
S12: the current outdoor temperature and the current indoor temperature are collected.
The inside and the outside of the pigsty are relative to the pigsty, the inside of the pigsty is the inside, and the outside environment of the pigsty is the outside, because the ventilation source of the negative pressure ventilation system is the outside air, and the outside temperature and the outside air temperature are obviously the same, the outside temperature influences the control of the temperature in the pigsty to a certain extent.
In the process of controlling the temperature and the humidity in the pigsty, the temperature of the indoor environment is controlled within the comfortable temperature range of the pigsty, and the humidity is not lower than a certain humidity threshold.
For this purpose, a standard temperature T0 may be set for the outdoor temperature; the highest comfortable temperature of the swinery is Ta, the lowest comfortable temperature of the swinery is Tb, namely the comfortable temperature range of the swinery is (Ta, Tb); the current outdoor temperature is T1, and the current indoor temperature is T2; in theoretical situations, the current outdoor temperature and the current indoor temperature collected have the following 6 situations:
1)T1>T0,T2>Ta;
2)T1>T0,Tb<T2<Ta;
3)T1>T0,T2<Tb;
4)T1<T0,T2>Ta;
5)T1<T0,Tb<T2<Ta;
6)T1<T0,T2<Tb。
it should be noted that, for the standard temperature T0, it can be used as a standard for judging whether the current environment belongs to a summer environment or a winter environment. When the ambient temperature is higher than the standard temperature, the ambient temperature is higher, and the current ambient temperature is warmer; and when the temperature is lower than the standard temperature, the current environment is cold.
Therefore, for the above 6 cases, when the current outdoor temperature is higher, i.e. T1> T0, the temperature of the above 3) case does not appear normally because the swinery itself also belongs to the heat source. The case 3) is therefore temporarily not considered in this application.
Similarly, for the case 4) above: t1< T0, T2> Ta, normally, the ambient temperature is low, even if the swinery radiates heat, the temperature in the piggery is difficult to rise to above Ta due to the cooling effect of the temperature of the introduced air. Therefore, the above-mentioned case 4) is not generally found, and this case is not considered in this embodiment.
S13: and if the current outdoor temperature is greater than the standard temperature and the current indoor temperature is greater than the highest comfortable temperature of the swinery, controlling the ventilation quantity of the negative pressure ventilation system according to the current indoor temperature and controlling the spraying system to spray liquid water to the surface of the swinery.
When the temperature in the pigsty is adjusted by water spraying and ventilation, the temperature is mainly determined according to the current indoor temperature and the current outdoor temperature of the pigsty. During the actual adjustment, a corresponding set of water spray and ventilation data may be determined for each set of current outdoor and indoor temperatures. It may also be determined whether adjustments to the current amount of water spray and ventilation need to be made based on the current outdoor temperature and the current indoor temperature.
S14: and if the current outdoor temperature is lower than the standard temperature and the current indoor temperature is lower than the lowest comfortable temperature of the pigsty, controlling the ventilation quantity of the negative pressure ventilation system according to the current indoor temperature and controlling the spraying system to spray the foggy water into the pigsty space.
When the pig house is sprayed with water, two different water spraying modes can be adopted, namely spraying mist water and spraying liquid water.
The effect is not the same for spraying water in different states. Generally speaking, the negative pressure ventilation device is more suitable for spraying liquid water in summer with higher temperature, the liquid water is directly sprayed to the body surface of a swinery, water on the body surface of the swinery is evaporated under the action of ventilation so as to take away a large amount of heat, and the temperature of the swinery is reduced; for the mode of direct water spray in to the pig house space, directly spray water to the swinery body surface in this embodiment, just also be equivalent to directly cooling the swinery body surface, the ventilation of deuterogamying negative pressure ventilation system increases the air current circulation, can promote the cooling effect of water spray cooling to a great extent, reduces the water consumption on the purpose basis that reaches the cooling.
And the device is more suitable for spraying mist water in winter with relatively low temperature, and can basically fulfill the aim of radiating heat in the pigsty in winter only by ventilation. But the pig house need keep certain humidity again, for this reason avoid the water spray to take away too much heat in the pig house, spray fog water in the application to the pig house space, can enough remove dust and moisturize, can avoid again because directly to the too much problem of swinery body surface cooling that leads to the water spray of swinery body surface.
Whether to spray mist water or liquid water in actual determination may be decided based on whether the current outdoor temperature belongs to a summer temperature higher than the standard temperature or a winter temperature lower than the standard temperature.
As described above, for 6 cases where the current outdoor temperature and the current indoor temperature exist, the 3) th and 4) th cases may not exist generally, and for the 1) th and 2) th cases where the current outdoor temperature is higher than the standard temperature, liquid water may be sprayed to the herd of pigs. And for the cases of 5) and 6), it is possible to spray the pigsty space with mist-like water.
Of course, it is also possible to combine the current indoor temperature and the current outdoor temperature to determine whether to spray mist water or liquid water, for example, if the situation 3 actually occurs in the practical application, it indicates that the temperature in the pig house is reduced excessively, and although the outdoor temperature is too high, the liquid water may be sprayed. And aiming at the situation in the 4) the purpose that the temperature can not be reduced by only depending on ventilation although the outdoor temperature is lower but not too low is shown, and liquid water can be sprayed on the surface of the swinery to achieve the purpose of reducing the temperature.
It should be noted that, in the actual control process, in general, no matter whether the current outdoor temperature is higher than the standard temperature or lower than the standard temperature, as long as the current indoor temperature is within the comfortable temperature range of the swinery, the previous water spraying mode and ventilation mode only need to be maintained unchanged.
In summary, when the temperature and humidity of the pigsty are controlled and the current indoor temperature is too high, the purpose of rapid cooling is achieved by adopting negative pressure ventilation and directly spraying liquid water to the surface of the pigsty body, and the waste of water resources is reduced to a certain extent; and when present indoor temperature is unlikely to too high, adopt negative pressure ventilation and reach the purpose of dust removal ventilation to the spray fog water in pig house space for the humiture in the pig house adjusts more rationally effectively, has guaranteed the comfort level of pig house swinery.
Based on the above discussion, the specific control manner of the piggery temperature and humidity will be described in detail below for different situations of the current indoor temperature and the current outdoor temperature.
In an optional embodiment of the present application, if the current outdoor temperature is greater than the standard temperature and the current indoor temperature is greater than the highest comfortable temperature of the swinery, controlling the ventilation volume of the negative pressure ventilation system and controlling the spraying system to spray liquid water to the surface of the swinery according to the magnitude of the current indoor temperature may include:
setting a first upper limit ventilation quantity according to the current outdoor temperature;
determining a first temperature difference between the current indoor temperature and the highest comfortable temperature of the swinery;
and under the condition that the ventilation quantity is not greater than the first upper limit ventilation quantity and not less than the lower limit ventilation quantity, setting the ventilation quantity and the water spraying quantity according to the positive correlation among the magnitude of the first temperature difference, the increment of the ventilation quantity and the increment of the water spraying quantity.
It should be noted that the current outdoor temperature is greater than the standard temperature, which indicates that the outdoor temperature is already high, although ventilation can increase airflow circulation, since the wind source is from the outdoor, the effect of ventilation on cooling is relatively weak, and the higher the current outdoor temperature is, the higher the temperature of the introduced wind volume is. Therefore, it is necessary to set an upper limit value of the ventilation amount to avoid excessive heat from the outside of the room. And the higher the current outdoor temperature is, the smaller the upper limit of the ventilation amount is.
The manner of increasing the ventilation amount differs depending on the blower used, and for example, for a blower that is started at intervals of a certain time, the control of increasing the ventilation amount can be realized by shortening the intervals at which the blower is started. Aiming at the fan which can directly shift the ventilation volume, the gear of the ventilation volume is increased.
When the indoor temperature and the outdoor temperature are relatively high, the water spraying amount needs to be increased to achieve the purpose of better cooling, the increased amount of the water spraying amount is also related to a first temperature difference between the current indoor temperature and the highest comfortable temperature of the swinery, the larger the first temperature difference is, the larger the water spraying amount is, and the water spraying amount is also related to the size of the first temperature difference.
The relationship between the increase of the ventilation volume and the increase of the water injection volume and the first temperature difference can be determined through multiple tests, or by acquiring a large amount of sample data and performing computer learning or other analysis and research modes, and the method is not particularly limited in the present application.
Of course, if the high temperature leads to the water spray volume great to lead to current indoor humidity too big, then can send out high wet warning when current indoor humidity is greater than the predetermined humidity threshold value, take corresponding measure with the suggestion staff, avoid producing ponding etc. in the pig house.
In addition, similar to the way of controlling the ventilation volume, the water spraying flow rate sprayed by the water spraying nozzle is generally fixed, and if the water spraying volume is increased, the time interval between two adjacent water spraying times can be shortened.
In another optional embodiment of the present application, when the current outdoor temperature is less than the standard temperature and the current indoor temperature is less than the minimum comfortable temperature of the pigsty, then controlling the ventilation amount of the negative pressure ventilation system and controlling the spraying system to spray the foggy water into the pigsty space according to the magnitude of the current indoor temperature may include: .
Setting a second upper limit ventilation quantity according to the current outdoor temperature;
determining a second temperature difference between the lowest comfortable temperature of the swinery and the current indoor temperature;
and under the condition that the ventilation amount is not more than the second upper limit ventilation amount and not less than the lower limit ventilation amount, setting the ventilation amount according to the positive correlation between the magnitude of the second temperature difference and the reduction amount of the ventilation amount.
If the current indoor temperature and the current outdoor temperature are relatively low, the ventilation quantity is obviously required to be reduced, and the phenomenon that the excessive temperature in the pigsty is taken away by ventilation is avoided. For the swinery in the closed pigsty, no matter the indoor temperature is higher or lower, ventilation and air exchange are needed to ensure oxygen supply, so that the ventilation quantity is not lower than the lower limit ventilation quantity no matter the indoor temperature or the outdoor temperature.
When the outdoor temperature is too low, too much ventilation quantity can take away too much heat in the pigsty, so that the temperature in the pigsty is too low. Therefore, the upper limit ventilation amount can be set to the ventilation amount, and it is apparent that the lower the current outdoor temperature is, the smaller the upper limit ventilation amount at this time is.
In addition, the indoor temperature and the outdoor temperature are both low at the moment, the spray mist water is suitable for ensuring the indoor humidity, meanwhile, the humidity in the pigsty is also required to be detected in real time, and the current indoor humidity is required to be in negative correlation with the water spraying amount.
It should be noted that the main purpose of water spraying is to keep moisture and remove dust, and compared with liquid water, the effect of mist water sprayed in the pigsty space on reducing the temperature of the surface of the pigsty is much smaller than that of liquid water spraying to the surface of the pigsty. Therefore, the amount of sprayed water sprayed at this time is mainly determined by the humidity factor in the piggery environment. Can be through humidity transducer real-time supervision pig house environment humidity, humidity is big more, and the volume of spraying water is little, otherwise humidity is little, and the volume of spraying water is big more.
