基于物联网的猪舍环境监测系统

Environmental Monitoring System of Pig House based on Internet of Things

为了实时掌握猪只生长环境的情况,满足猪舍环境的监测需求,同时降低系统的成本,设计了一款基于物联网的猪舍环境实时监测系统。系统选用STM32F103C8T6单片机作为主控器,应用空气温度、空气湿度、光照强度、CO_(2)浓度、NH_(3)浓度等传感器对猪舍环境进行实时检测,并根据检测结果对异常情况进行报警或控制。系统选用ESP8266 Wi-Fi模块通过MQTT协议连接OneNET物联网平台,实现数据的远程传输,便于数据的可视化显示和管理。研究中根据物联网架构模式搭建了系统,对系统所需硬件进行了分析,经核算总计成本在150元左右,并对网络、功耗和数据准确性进行了测试,结果表明系统总体稳定可靠。该系统集多传感器于一体,可以同时监测多种环境因子,且成本低、简捷易用,能够为猪只提供较好的生长环境,能够帮助养殖人员进行科学化管理,从而提高产能和收益。

In order to grasp the situation of pig growing environment in real time,meet the monitoring requirements of pig house environment,and reduce the cost of the system,a real-time monitoring system of pig house environment based on Internet of Things was designed.The system uses STM32F103C8T6 single chip microcomputer as the main control,uses air temperature,air humidity,light intensity,CO_(2) concentration,NH_(3) concentration and other sensors to detect the environment of the pig house in real time,and alarms or controls the abnormal situation according to the detection results.The ESP8266 Wi-Fi module is used to connect the OneNET Internet of Things platform through MQTT protocol to realize the remote transmission of data and facilitate the visual display and management of data.In the research,the construction of the system is introduced according to the architecture model of the Internet of Things,the hardware required by the system is analyzed,the total cost is about 150 yuan,and the network,power consumption and data accuracy are tested,the results show that the system is stable and reliable.The system integrates multiple sensors in one,can monitor a variety of environmental factors at the same time,and the cost is low,simple and easy to use,can provide a better growth environment for pigs,and can help breeding personnel to carry out scientific management,so as to improve productivity and income.
