Method to build microclimate model of closed laying hen brooding house based on computer simulation

Abstract

The present invention provides a method for building a microclimate model of a closed laying hen brooding house based on computer simulation. It constructs a heat change model, a humidity mass balance model and an ammonia concentration model of the brooding house. Based on the three models, the laying hens are built in the Simulink module. For the microclimate model of the brooding house, add the regulating module and controller to the model for simulation, compare the measured data with the model simulation data, adjust the output through the controller, and use the output to execute the start and stop of the regulating module through multiple D / A converters, which will affect the brooding. Adjust the model environment; send the simulation data of the model to the client's database for storage, for management personnel to view and analyze. The method for building a microclimate model of a closed laying hen brooding house based on computer simulation provided by the present invention uses computer simulation technology to establish a simulation model, which saves the cost of the experiment and reduces the impact of the experiment on the health of the chickens. By comparing with the measured data, it is determined that Model reliability.

Description

Technical field [0001] The invention relates to the technical field of establishing a microclimate model for chicken houses, and in particular to a method for establishing a microclimate model for a closed laying hen brooding house based on computer simulation. Background technique [0002] With the development of smart animal husbandry, welfare breeding is receiving more and more attention, especially in the brooding aspect of welfare breeding of laying hens. Due to China's vast territory, complex and diverse climate distribution, the environment in different regions varies greatly. In addition, The environment in the brooding house is affected by many factors, and the construction of brooding houses is very different in different regions. Therefore, artificial practical experiments are very inconvenient and costly. Most of the existing technologies use computer simulation technology to build simulated brooding house environmental climate models. CFD technology is generally...

Problems solved by technology

[0002] With the development of smart animal husbandry, more and more attention has been paid to welfare farming, especially in the brooding of laying hens. Due to China's vast territory, complex and diverse climate distribution, and large environmental differences in different regions, coupled with the The environment in the brooding house is affected by many factors, and the construction of the brooding house in different regions is very different, so manual practice experiments are very inconvenient and costly

Most of the existing technologies use computer simulation technology to build a simulated brooding house environmental climate model, and generally use CFD technology for environmental modeling, but this technology is very consistent with the actual situation for the complex airflow field. This technology requires the use of professional knowledge such as aerodynamics and fluids, and its programming is extremely difficult, and the code is difficult to understand and modify
