【摘要】：【目的】针对现有农业环境监测网关设备开发成本高、系统功耗大、操作复杂等不足,设计开发一种用于农业环境监测的无线传感器网络网关节点。【方法】网关节点以低功耗芯片CC2530为核心处理单元,通过外围状态指示电路、电源管理模块等,完成ZigBee网络组网和监测节点数据收集及处理功能;同时通过串口方式连接SIM900A模块,采用GPRS方式将监测数据上传至中心服务器。最后在农田进行了监测数据误包率与信号接收强度测试,并通过实地部署试验验证了系统的稳定性及可靠性。【结果】所设计的网关节点能实现4种农业环境数据的采集,节点间距小于120m时数据传输误包率低于1%,监测数据在30d农田试验期内连续变化,可长时间上传至服务器,且稳定性、可靠性良好。【结论】所设计开发的基于CC2530的网关节点具有丢包率低、运行稳定可靠的特点,能够满足多种农田环境因子的监测需求,具有良好的应用前景。
[Abstract]:[objective] in view of the existing agricultural environment monitoring gateway equipment development cost is high, the system power consumption is large, the operation is complex and so on. A kind of wireless sensor network gateway node for agricultural environmental monitoring is designed and developed. [methods] the gateway node uses low power chip CC2530 as the core processing unit, through the peripheral state indicator circuit, power management module, and so on, the gateway node uses the low power consumption chip CC2530 as the core processing unit. Complete the ZigBee network networking and monitoring node data collection and processing functions; At the same time, the SIM900A module is connected by serial port, and the monitoring data is uploaded to the central server by GPRS. Finally, the error packet rate of monitoring data and the signal receiving intensity are tested in farmland, and the stability and reliability of the system are verified by field deployment test. [results] the designed gateway node can realize the collection of four kinds of agricultural environmental data. When the node spacing is less than 120m, the data transmission error rate is less than 1%, and the monitoring data changes continuously during the 30-day farmland test period, and can be uploaded to the server for a long time, and the data is stable. [conclusion] the designed and developed CC2530-based gateway node has the characteristics of low packet loss rate, stable operation and reliable operation, which can meet the monitoring needs of a variety of agricultural environmental factors, and has a good application prospect.
