Description
Technical field
The present invention relates to a kind of poultry environment control method and device, particularly about a kind of open cattle farm cooling inter-linked controlling method based on respiratory rate and device.
Background technology
Summer high temperature weather oneself become a key factor of restriction China Milk Cow Production, Holstein cow is cold-resistant, and To Be Protected from Heat, and it is reported that temperature is 21 DEG C to 27 DEG C time, milk production and butterfat percnetage start slow decline, significantly decline more than 27 DEG C of milk productions.Usually, if meet with hot weather extremely of continuous a few days, milk cow even can be caused dead, cause huge economic loss.At present, the most dairy cow farm of China adopts open cattle farm, mainly following three types: the system that simple open cowshed, simple sports ground and open cowshed and sports ground combine.Because the environment conditioning of open raising is limited in one's ability, the milk cow under this kind of raising situation more should be paid attention in the heat stress situation in summer.
To resist cold the feature that To Be Protected from Heat for milk cow, suitable cooling measure must be taked season at summer high temperature, to alleviate the heat stress situation of milk cow.On engineer applied, the indoor normal ox body that uses sprays, and carries out trickle, promote moisture evaporation, to reach cooling object with rear venting to milk cow body surface.On playing field, take the measures such as sunshade, by reducing solar radiation to reduce heat stress pressure.Perfect not enough in cowshed cooling system control design case at present, research for cooling in summer equipment is uneven, seldom pointed automatic control system, mostly be manual operation, the regulation and control be suitable for can not be carried out with reference to the environmental baseline that the external world is different, hysteresis quality is obvious, directly has influence on the remission effect of heat stress.
In addition, even if adopt automatic control mode in existing system, choosing of control model and controling parameters, the general also simple environmental index around cowshed, do not contact the physical signs of milk cow, corresponding adjustment can not be made to the true reflection of milk cow, therefore can not reach best regulating effect.In actual production, respiratory rate evaluates a major physiological parameter of cow heat stress situation, but the heat stress situation relying on it to understand milk cow is only rested in producing at present around the application of respiratory rate, in environment conditioning, also it can be used as without any a kind of equipment and a kind ofly control required parameter, this also just causes control system and the actual disconnection experienced of milk cow indirectly, reduces the result of use of control system.
Due to the needs of milk cow life habit, most cattle farm is that milk cow is equipped with sports ground, except the time of taking food and have a rest, in one day, milk cow has considerable time to rest on sports ground, particularly during the broiling summer, when cowshed internal environment regulates and controls not good enough, milk cow even can rest on sports ground all day, this just requires that sports ground has a good environmental monitoring and regulate and control method, and investigates at present and knownly substantially do not use any correlation technique in cattle farm.
Divided by first-class aspects, in the most open cattle farm of China, existing monitor and control facility control objectives is centered around in house, the cooling of sports ground and cowshed inside is not controlled to combine.When sports ground is gone in the spray position that most milk cow has left cowshed, the spray system in house is still run, or when sports ground milk cow number is few, the sunscreen spray device of sports ground does not stop, and which results in the waste of resource.Therefore, be necessary to provide a kind of control method and the device that can realize sports ground and cowshed interlock based on milk cow respiratory rate.
