A Birdhouse Environmental Control System For Large-Scale Broiler Healthy Breading

At the present stage poultry farming in our country is developing toward intensification and large scale. People raise more strict requirements about the environment of the birdhouse. The development of birdhouse environment control system provide a comfortable living environment for chicken, and reduce the rate of the disease. It has important significance on improving the quality of the chicken and increasing market competitiveness. It provides necessary technical assurance for the standardization production of poultry industry in our country and gain international market share.This article designed a birdhouse environmental control system for large-scale broiler healthy breading by combining with poultry breeding requirements and birdhouse environmental characteristics, analyzing each environment impact factor in poultry houses and combining the microelectronics technology, sensor technology and modern control theory, etc. This article has completed the hardware and software design of the system and the anti-interference research, formulated the environmental control strategy and debugged the system.This system through the data acquisition module to collect all the environmental impact factor parameters and then transfer the parameters to the control module. Single-chip microcomputer according to the control strategy to analyze the data and then sends control signals. Driver module according to the execution of this signal to drive the corresponding equipment operation, then it can adjust the comfortable environment for poultry houses. Through the human-computer interaction module, the user can observe the changes in the environment within the birdhouse in real time, and revise the parameters in order to apply different day age chickens on the environment. Users can also through the set temperature and humidity curves and weight curves to realize the parameter automatic invocation. In order to solve the opposing problem of thermal insulation and ventilation when the winter temperature is too low, this article designed the positive pressure ventilation and worked out the corresponding control strategy.The poultry house environmental control system in this article can complete the control of poultry house temperature, humidity, ventilation and lighting, material line. This system can realize the environment parameters setting and important parameters display. The system control panel is easy for observation and easy to operate. The system is fully functional, stable and reliable, and the operation is simple. And it can provide comfortable environment for poultry. It has important significance in improving the market competitiveness and in improving the economic benefits of poultry in China.
