设施羊舍环境信息监控系统的设计

Design of environmental information monitoring system for sheep house

为了实时监测与控制分娩母羊舍环境信息,减少外界环境因素对产羔母羊的影响,提高羔羊成活率,实现福利化养殖,研究设计了一种基于无线传感网络(Wireless sensor network,WSN)实时对羊舍环境信息监测与控制的系统。系统以RS485-WIFI协议转换器将传感器与控制器接入局域网,通过2.4 GHz无线通信技术进行实现数据传输与访问控制。实现了实时数据采集,并保存在SQL Server数据库中,同时可将结果实时反馈给养殖人员,通过羊舍环境因子进行调控,实现预警与控制。结果表明:当每隔1 min采集一次时,通讯丢包率在1%以内,远程监控系统稳定,能满足设计及应用的要求。

To monitor and control of the environmental information of the sheep house for delivery ewes in real time, and reduce the influences of external environmental factors on the production of lambs and improve the survival rate of lambs to realize the welfare breeding, a system scheme based on wireless sensor network （WSN） for real - time monitoring and control of the environmental information of sheep house is pro- posed. This system makes the sensor and controller be connected to the LAN by the RS485 - WIFI protocol converter, and achieves data trans- mission and control access through a 2.4 GHz wireless communication technology. Real - time data acquisition is realized and stored in the SQL Server database. At the same time, the results can be real - time feedback to the breeding staff, and the early warning and control can be real- ized through regulating and controlling the sheep house environmental factors. The results show that the communication loss rate is less than 1% when the data is collected every 1 min, and the remote monitoring system is stable. It is proved that the system scheme can meet the design and application requirements.
