摘要
为了大范围、低成本实现智能节水灌溉,采用ZigBee无线传感器网络技术,提出了一种利用S3C2440与CC2430作为主控芯片的节水灌溉系统设计方案。系统通过CC2430的串口采集土壤湿度传感器数据,并将数据通过ZigBee无线网络上传给数据处理中心;数据处理中心由CC2430通过串口将接收到的数据传递给S3C2440,同时采用SD卡进行存储,并通过光纤以太网接口将数据进行远端传输。经过SmartRFStudio信号软件和Linux下的Hping指令测试,灌溉系统连续7天无故障运行,完全达到系统设计指标。
For large-scale and low-cost intelligent water-saving irrigation, a water-saving irrigation system design is pro- posed by using S3C2440 chip and CC2430 as the main control chip based on ZigBee wireless sensor network technology. The system collects data of soil moisture sensor with the serial port of CC2430, and uploads the data to the data processing center via ZigBee wireless network, the data processing center transfers the received data to the S3C2440 through the serial port by CC2430, at the same time the system uses SD cards for storage and transmits the data through the optical Ethernet interface remotely. The irrigation system has operated without trouble for 7 days, and has completely met the design requirement by the test of SmartRFStudio signal software and the Hiping command of Linux.
