Research on intelligent control technology of chicken house environment in large-scale chicken farms

In order to solve the problem of the influence of dust particles and toxic gases on the growth of chickens in chicken houses faced by large-scale chicken farms, this study aims to develop an intelligent control system for chicken house environment in chicken farms, and to explore the solution of intelligent control of chicken house environment by utilizing the Internet, the Internet of Things (IoT), and high-voltage electrostatic and plasma technologies.This study uses a function-driven development approach, using basic hardware such as sensor fusion hardware, communication equipment, high-voltage electrostatic precipitator, and plasma discharge device, and completes the system function development using the ROS (Robot Operating System) embedded development platform and the Java language to determine the usability and reliability of the system by running tests in chicken farms.The core functions of the system include environmental de-dusting and purification by adjusting the strong discharge field, and deodorization and disinfection purification by the plasma reactor. The high-voltage electrostatic discharge technology designed in this study can realize the automatic adjustment function, and the discharge docking area and discharge gap can be changed by rotating the button, so as to change the discharge field strength and achieve different purification design requirements. The plasma reactor adopts a honeycomb structure, the blocking medium is enameled, in order to ensure uniform discharge, the conductive layer is plated onto the enamel plate, the other side of the electrode is made of planed 316 stainless steel plate, the high-speed phase-locked loop MM74HC4046 is used to lock the operating frequency, and the power is automatically adjusted using the PFM method, and the resonant capacitor adopts the new type of capacitor that has a large capacity and a small ESR of the equivalent series resistance. Through the actual operation test in the chicken farm, users are satisfied with the usability, ease of use and reliability of the system and equipment.In this study, an intelligent control system for chicken house environment was designed to create a comfortable and good developmental environment for chickens, to effectively improve the level of intelligent farming, and to provide sufficient experimental basis and theoretical support for the environmental management and optimization of chicken houses.
