基于无线网络的羊舍环境参数采集控制系统设计

摘要

[ Objective] The intensive, digital and intelligent management of sheep pen could be ensured through the research on real-time ac-quisition of the environmental parameter in the sheep pen. [ Method] The real-time acquisition of environmental parameters of temperature, humidity, CO2 concentration, NH3 concentration in sheep pen was carried out with the technique of ZigBee short-range wireless and GPRS and the data was fast and accurately transferred to the management system in PC, so that the healthy sheep growth would be realized through the optimum environment based on the remote and automatic control in the ventilation, heating and others. [ Result] The environment parametes in sheep pen could be stably collected with the system. The timely alarming and the starting of the appropriate control equipment were done when the environmental parameters in sheep pen exceeded the threshold that was set. [ Conclusion] The system is simple and user-friendly, stable and timely warning, and to some extent, the automation level of sheep pen management is improved.%[目的]实现养羊业集约化、数字化和智能化管理，保证羊舍环境参数的实时采集。[方法]以畜牧业中羊舍的养殖环境作为研究对象，运用ZigBee短距离无线技术和GPRS技术，实现对羊舍环境中温度、湿度、CO2浓度、氨气浓度的实时采集，并将其快速、准确地传送于上位机的羊舍环境参数管理系统，可远程或自动控制通风、加温等设备，以保证羊舍内的环境适宜羊只健康生长。[结果]该系统可实现羊舍环境参数的稳定采集，当环境参数超出设定的阈值时，能及时报警并启动相应的控制设备，使羊舍的环境参数变化在设定的范围内。[结论]该系统操作界面简单友好，运行稳定，能及时报警，一定程度上提高了羊舍管理的自动化水平。
