Design of the Remote Monitoring System for Pigsty Environment Parameters Based on the on IoT

For the needs of the monitoring requirements for pigsty environment, based on IoT (Internet of Things) framework, a three-tier architectural model for the remote monitoring system of pigsty environment parameter is designed. The system consists of three parts, which are field acquisition control subsystem, remote monitoring subsystem and database. The environment parameters and the states of control equipment are collected using STM32 SCM, and the collected data saved to the database in real time. In order to improve the response speed and interaction of the remote monitoring subsystem, JavaScript and Ajax asynchronous data exchange mechanism is used to upload the collected data in real time to the web page for display, and the control equipment can accept the orders in real time. The experimental results show that the operation of the system is stable and the transmission of data is correct. It can effectively control the environment and satisfy the demand of piggery environmental monitoring.
