【摘要】：针对目前鸡舍测量环境参数的各种仪器操作复杂,检测效率低,同时鸡舍内报警系统存在的问题,本研究设计了一种基于物联网的鸡舍环境监控报警系统。该系统主控芯片为STM32,主要完成对鸡舍环境温湿度、二氧化碳、氨气、PM2.5、PM10数据实时监测以及温湿度超过阈值、鸡舍断电、风机故障电话短信报警。系统性能测试结果表明,鸡舍传输距离在11m左右,丢包率为0.2%,温度测量相对误差为0.71%,湿度测量相对误差为1.91%,温湿度超过阈值、鸡舍断电以及风机故障系统能及时短信电话报警,用户可以通过客户端对舍内环境参数进行实时查询。在半封闭式育雏鸡舍对0日龄的鸡进行一周(2016/10/212016/10/27)的环境参数监测结果表明:测试位置与二氧化碳极显著正相关(P0.01),同时与氨气极显著负相关(P0.01),湿度与PM10呈显著正相关(P0.05),PM10与PM2.5呈极显著正相关(P0.01),温度与湿度呈极显著负相关(P0.01),在不同位置测量鸡舍的环境参数反应鸡舍整体的环境质量。该系统能够连续精确监测鸡舍环境参数、及时预警,提高鸡舍饲养管理水平,应用前景广阔,适用于精准畜牧。
[Abstract]:In view of the complex operation and low detection efficiency of various instruments for measuring environmental parameters in chicken coop at present, and the problems existing in the alarm system in chicken coop, a chicken coop environmental monitoring and alarm system based on Internet of things is designed in this paper. The main control chip of the system for STM32, mainly completes the real-time monitoring of environmental temperature and humidity, carbon dioxide, ammonia, PM2.5,PM10 data, temperature and humidity exceeding the threshold, power outage of chicken coop, fan fault telephone short message alarm. The results of system performance test show that the transmission distance of chicken coop is about 11m, the packet loss rate is 0.2%, the relative error of temperature measurement is 0.71%, the relative error of humidity measurement is 1.91%, and the temperature and humidity exceed the threshold. The chicken house power outage and fan fault system can timely SMS telephone alarm, users can query the environmental parameters of the house in real time through the client. The environmental parameters of 0-day-old chickens were monitored in a semi-closed brooding coop for one week (2016 / 10 / 21 / 06 / 10 / 27). The results showed that there was a significant positive correlation between the test position and carbon dioxide (P 0.01). At the same time, it was negatively correlated with ammonia (P01), humidity was positively correlated with PM10 (P05), PM10 was positively correlated with PM2.5 (P01), and temperature was negatively correlated with humidity (P01). The environmental parameters of chicken coop were measured at different positions to reflect the overall environmental quality of chicken coop. The system can continuously and accurately monitor the environmental parameters of chicken coop, timely early warning, improve the level of chicken house feeding and management, and has a broad application prospect, which is suitable for accurate animal husbandry.
