摘要
针对现有温室大棚种植园环境监测的缺陷和不足,采用物联网技术,设计对温室大棚远程监控的系统。文中提出了模糊功率控制算法,以接收信号强度和丢包率变化作为模糊控制器的输入,实现对传感器节点的发射功率自动调整。以低功耗CC2530为处理器,通过传感器节点模块采集数据后传输到汇聚节点模块,再由汇聚节点模块传输数据到网关节点模块,最后通过GPRS模块将数据上传到服务器。实验结果表明,所提系统运行稳定,采集的数据准确,可以实现对温室大棚种植园的环境监测。
In view of the defects and insufficiency of the existing greenhouse plantation environmental monitoring,a remote monitoring system for greenhouses is designed by means of the Internet of Things(IoT)technology. A fuzzy power control algorithm is proposed for this system,which takes the received signal strength and packet loss rate as the input of the fuzzy controller to realize the automatic adjustment of the transmit power of the sensor node. Besides,low power consumption CC2530 is used as processor. The sensor node module is adopted to collect data,and then send the data to the sink node module,by which the data is transmitted to the gateway node module. Finally,the data is uploaded to the server through the GPRS module,so as to realize the monitoring of the PC upper computer. The experimental results show that the system operates stably and the collected data is accurate. It can realize the environmental monitoring of the greenhouse plantation.
