Description
Technical Field
The invention relates to the field of livestock and poultry breeding environment control, in particular to a cowshed cooling control system based on temperature and humidity monitoring.
Background
A large amount of relevant data and researches at home and abroad show that heat stress is caused to beef cattle, the lowest critical growth environment temperature is 27.0 ℃, the lowest critical growth environment temperature and humidity index (TH) of moderate heat stress is 79, and when the Temperature and Humidity Index (THI) of the milk beef cattle growth environment is 88, the beef cattle can be severely heat-stressed and only the beef cattle production performance is reduced, so that the beef cattle can be discomfortable and even die.
In hot summer, beef cattle in the cowshed are in a heat stress state after entering the cowshed for 6 months, and the heat stress can obviously influence the reproductive capacity and the sick probability of the beef cattle, so that the serious economic benefit loss of farmers is caused. In order to reduce the influence of cattle heat stress and reduce the economic loss caused by the influence, the temperature of the cowshed is particularly important to be reduced.
In the beef cattle breeding industry in China, in order to ensure the production capacity of beef cattle, the quality of high-yield genes is always used as a main standard for breeding, and the selection of heat stress resistant genes is ignored. Therefore, beef cattle are often not sufficiently resistant to high temperature and high humidity. In China, in order to weaken the disadvantage of high temperature to beef cattle, cooling measures are adopted, such as fan cooling, house shading cooling, high-pressure spray fan cooling, wet curtain fan cooling and the like.
Among them, the cooling and humidifying effects of the high-pressure spray fan and the wet curtain fan system are the best. The high-pressure spray fan system mainly comprises a high-pressure spray device, a circulating fan and an intensive control host; wherein, a spray head of the high-pressure spraying device is arranged on a cross beam of the cowshed, and the position of the spray head ensures that spraying particles are completely evaporated when falling on the ground of the cowshed; the height from the installation position of the circulating fan to the ground is less than the installation height of the spray head, and the direction is longitudinal; the intensive control host controls the automatic opening and closing of the high-pressure spraying device and the circulating fan, and the cooling and humidifying mode is that the high-pressure spraying pipeline and the circulating fan are installed at reasonable positions, so that fog drops are uniformly distributed in a house space to improve the cooling efficiency of the system. However, the temperature-reducing humidifying water is too obvious in the improvement of the humidity coefficient in the house, although the indoor humidity is too high due to the fact that the temperature is reduced through strengthening spraying, the temperature and the humidity suitable for the growth and the reproduction of beef cattle are difficult to control in the house, the spraying effect is obvious compared with the spraying temperature-reducing effect, but the water amount generated by spraying is also large, the water accumulation of a beef bed and the water accumulation of a feed channel are often caused, the feed intake rate of the beef cattle and the utilization rate of feed are reduced, and meanwhile, the cattle body is also uncomfortable.
The cooling principle of the wet curtain fan system as another commonly used cooling and humidifying system is that negative pressure generated in a cavity can be introduced when the fan operates, air outside an air cooler flows through the porous wet curtain surface, the dry bulb temperature of the wet curtain air is reduced to be close to the wet bulb temperature of the air outside the air cooler, the dry bulb temperature of an outlet of the air cooler needs to be 5-12 ℃ lower than the outdoor temperature, 15 ℃ can be reached in a dry area, the temperature difference of the air is larger as the air is drier, and the cooling effect is better. Because the air is led into the room from the outside, the air is also called as a positive pressure system, so that the air in the room can be kept fresh continuously; the principle of the air cooler is that evaporation is used for cooling, so that the temperature of the cowshed is reduced, and a certain humidification effect is achieved. However, things tend to be two-sided. Although having many advantages, the wet curtain fan system still has some disadvantages as a practical cowshed cooling and humidifying device. The continuous operation of a wet curtain fan system at night can cause the condition of excessive space humidity. For beef cattle, the harm of high temperature and high humidity is very serious. When the ambient humidity is increased, because the air is saturated with moisture, sweat is not easy to evaporate and stays on the surface of the skin, the effect of evaporation and heat dissipation is seriously weakened, the normal physiological function is disturbed, the damage of heat stress to the body is aggravated, and summer disease is induced. Under the condition of low temperature and high humidity, the energy consumption additionally generated for maintaining the body temperature of the beef cattle is increased, the feed-meat ratio of the beef cattle is increased, and the breeding cost is increased. For calves, the calves are more dangerous at low temperature and high humidity. The water vapor capacity and the heat conductivity in the air are increased, the non-evaporative heat dissipation of the calf body is aggravated, the temperature regulator of the calf is not strong, excessive heat loss is caused, the calf body is easily cooled or even frostbitten, and the cold stress injury of the body is increased. Under the conditions of low temperature and high humidity, cattle are susceptible to various cold diseases and digestive tract diseases.
By analyzing two common cooling and humidifying devices, we can find that both devices can cause the phenomenon of overhigh humidity of the cowshed. And the beef cattle are easy to have various problems in a humid environment, which directly causes the economic loss of farmers. Therefore, a device which can meet the requirement of cooling the cowshed and can ensure relatively low humidity is urgently needed.
