Digital intelligent microclimate control of livestock farms

Abstract

The article presents the livestock structural and hardware implementations, the element base of digital intelligent microclimate control’s systems, the tasks must be solved in the light of microclimate quality imposed by livestock production modern technologies’ requirements are formulated. It is shown that the microclimate quality by changing of heating (cooling) power and air exchange equipment based on air environment’s temperature, humidity, and carbon dioxide content’s measurements is provided. An animals’ premises microclimate parameters’ automatic discrete-analog-digital control has been developed. The livestock farm premises’ microclimate system controlling hardware implementation’s scheme, including two levels: an electronic computer (farm), controllers with control and measuring devices, an interface, and executive devices (premises) has been developed. The information flows in the control system are determined: tasks are sent from the computer to the controllers for the current values of temperature, humidity, air pollution in the rooms, controllers in communication with measuring devices (radio channel), ventilation, heating (cooling) control devices. An example of the optimal microclimate control system’s effectiveness on 1300 heads of pigsty-feedlot is shown.
