Closed laying hen brooding house microclimate model building method based on computer simulation

The invention provides a closed laying hen brooding house microclimate model building method based on computer simulation. The building method comprises the following steps: building a heat change model, a humidity mass balance model and an ammonia concentration model of a brooding house, building a laying hen brooding house microclimate model in a Simulink module based on the three models, adding an adjusting module and a controller in the model for simulation, comparing actual measurement data and model simulation data, adjusting output through the controller, the output executes starting and stopping of the adjusting module through a plurality of D/A converters, and adjusting the environment of the brooding house; and sending simulation data of the model to a database of a client to be stored and used for checking and analyzing of a manager. According to the closed laying hen brooding house microclimate model building method based on computer simulation, the simulation model is built through the computer s
