Description

Technical Field

[0001] The present invention relates to the technical field of precision spraying for cow sheds, and in particular to a precision spraying method and a spraying control system that can be used for ventilating cow sheds in summer. Background Art

[0002] In the hot summer season, cattle are prone to heat stress, which can cause a significant decline in their production performance or even death. With the continuous improvement of environmental control technology in the cattle industry, more and more cattle sheds generally use fans and other equipment to improve the ventilation effect of livestock sheds in summer, and increase the convective heat dissipation and evaporative heat dissipation of cattle by increasing wind speed, which can alleviate the heat stress reaction of cattle to a certain extent. On the basis of increasing wind speed, if the heat stress of cattle is not effectively alleviated, it is necessary to start spraying in time to further reduce the adverse effects of high temperature on cattle. It is very important to determine the heat stress state of cattle under ventilation conditions and spray in time and accurately to reduce the heat stress reaction of cattle.

[0003] The existing heat stress detection method comprehensively judges the heat stress state of cattle through temperature and humidity, without considering the important factor of wind speed, and the fact that most cattle farms generally use large fans to increase ventilation in the shed in summer; the existing perceived temperature threshold takes both temperature and humidity into consideration, but the setting of the threshold does not comprehensively consider the influence of temperature, humidity and wind speed, and is not suitable for heat stress evaluation of cattle in ventilated cattle sheds; different cattle breeds and ages affect the critical temperature of cattle, and the uniformly set heat stress assessment formula for cattle cannot accurately reflect the body thermal balance state of cattle, and cannot provide an effective warm environment reference for cattle production.

[0004] In addition, most of the existing cowshed sprinkler systems are simply set to open at a fixed point, open according to the ambient temperature, and open when the cow is near the sprinkler head. The body heat balance state of the cow under ventilation conditions at that time is not taken into account, resulting in heat stress in the cow and the sprinkler is not turned on in time when it is near the sprinkler, and the sprinkler is still turned on when the ventilation has alleviated the heat stress of the cow. The system cannot timely and effectively adjust the heat storage of the cow and the opening and closing of the sprinkler according to the combined influence of temperature, humidity and wind speed, which also greatly increases the sewage treatment pressure at the rear end of the breeding. The existing sprinkler sensing device mainly regulates the opening and closing of the sprinkler through infrared sensors, photoelectric sensors or ultrasonic sensors. The infrared sensing device senses the presence of the cow by detecting the heat on the cow's body, which is easily disturbed by various heat sources and hot air currents in the environment, and even causes the failure of the sensing system. Photoelectric sensors such as reflected or diffuse reflection types sense the presence of the cow by detecting changes in light signals, which are easily disturbed by other objects or light sources in the environment. Ultrasonic sensors sense the specific position of the cow by detecting the reflected ultrasonic echo, which is easily disturbed by other objects in the environment, so improvements are needed.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0048] A precise spraying method for ventilating a cowshed in summer comprises the following steps:

[0049] S1. Install ventilation and cooling fan equipment in the cowshed, and install RFID ear tags on the ears of the cows to fully detect the temperature, humidity and wind speed of the cows and determine the body heat balance of the cows;

[0050] S2. The detected situation is transmitted to the corresponding control device. The control device issues instructions according to the pre-set program to obtain the dry bulb temperature Td, wet bulb temperature Tw and wind speed V of the environment in which all cows in the cowshed are located in high temperature weather, and calculates the body temperature ET of the cow; at the same time, it is compared with the set body temperature threshold ET. Ts For comparison; when the body temperature ET≤ET Ts When the body temperature ET>ET Ts When the cow is in a state of heat stress, it is determined that the cow needs to be cooled by the spray system so that the corresponding components can operate accurately. The situation of each cow can be accurately understood to better control whether to perform the spraying operation;

[0051] Before setting the program, you need to randomly select multiple cows in good health in a cowshed with ventilation equipment set up and turned on, and select hot weather with an average daily temperature of 27-37℃ for at least three days. Measure the dry bulb temperature Td, wet bulb temperature Tw and wind speed V of each cow's environment at 7:00, 14:00 and 19:00 in the hot weather, as well as the average skin temperature Ts of each test cow;

[0052] Secondly, the measured data of each selected cow at 7 o'clock, 14 o'clock and 19 o'clock in hot weather were entered into Excel software, and a three-variable linear regression model of dry-bulb temperature Td, wet-bulb temperature Tw and wind speed V on average skin temperature Ts in hot weather was established. Excel was used for data analysis to obtain the linear regression equation formula of dry-bulb temperature Td, wet-bulb temperature Tw and wind speed V on average skin temperature Ts:

[0053] Ts=k+a×Td+b×Tw+c×V(1)

[0054] Where k is the intercept, a is the regression coefficient of the independent variable dry-bulb temperature Td, b is the regression coefficient of the independent variable wet-bulb temperature Tw; c is the regression coefficient of the independent variable wind speed V;

[0055] According to formula (1), the calculation formula of the perceived temperature ET can be obtained:

[0056] ET=[a / (a+b)]×Td+[b / (a+b)]×Tw+[c / (a+b)]×V

[0057] Finally, a univariate linear regression model of perceived temperature ET and average skin temperature Ts under high temperature weather was established in Excel software to obtain the perceived temperature threshold ET when the average skin temperature Ts was set. Ts ;

[0058] S3, operating the first pulley assembly by controlling the device, and realizing the positional relationship between the component and the belt in the first pulley assembly by the first electric telescopic assembly, so as to achieve the purpose of transmission and synchronous movement, so as to reciprocate at the top of the cowshed;

[0059] S4, controlling the positional relationship between the second pulley assembly and the first pulley assembly to realize transmission, and controlling the position of the spraying component, so as to spray the cows with higher temperatures in the cowshed to effectively reduce the temperature;

[0060] S5. The purpose of effective spraying can be achieved by supplying water to the spraying parts through the water supply assembly.
