Design And Implementation Of Fixed Intelligent Monitoring System For Agricultural Microclimate

As the mode of pig breeding industry has evolved from traditional development to integrated and large-scale development,scientific breeding,which is realized by integrating modern information technology and digital technology into pig breeding,will not only increase economic profit,but also bridge the gap between China's agriculture and that of the developed agricultural countries.At present,an environmental monitoring system applicable to pig houses of various scale has been researched and designed.According to the actual application scenario,the overall design scheme based on the STM32 piggery environment monitoring system is designed.The piggery environment monitoring system is mainly composed of two parts: data acquisition controller and backend software.The data acquisition controller is mainly responsible for collecting information and transmitting the information to the backend software through the GPRS wireless network,such as air temperature and humidity,ammonia concentration,carbon dioxide concentration,light intensity,and operating status of each control device.The main research contents of this paper are as follows:(1)Hardware and software design of data acquisition controller.As for the hardware,there are the STM32 core controller and its basic circuits and control equipment,and the solar power supply system.As for the software,the ?C/OS-? real-time operating system is embedded on the STM32.(2)The backend software will receive the data transmitted by each data acquisition controller and input it into the MySQL database to monitor each piggery environment remotely.The environment monitoring system of the pig house designed in this article has the features of rich functions,stable reliability,and easy maintenance.It can not only realize the collection information and regulation of the pig house environment,but also can diversify the environmental data of each pig house.
