摘要
针对农田环境信息获取时存在的信息对象多、地域广、分布杂散、数据通讯条件落后等诸多不利因素,设计了采用基于无线传感器网络技术和可编程片上系统(SOPC)技术的便携式农田环境监测系统。该系统通过温度、湿度、光照度等传感器实时采集农田环境数据;以CC2430模块为终端测量节点的核心,建立无线传感器网络实现监测数据的无线传输和汇集;采用具有NiosⅡ嵌入式软核处理器的现场可编程门阵列(FPGA)控制系统实现对整个系统的管理。田间试验结果表明该系统能够有效地采集环境数据,并具有组网灵活、可扩展性强、携带方便等优点。
Portable FPGA environment monitoring system for farmland was designed based on technology of wirless sensor networks and SOPC according to the unfavorable factors existing in farmland environment,such as multiple information objects,vast region,scattered distribution,backward data communication condition,etc.The system acquired farmland environmental data including temperature,humidity,illumination in real-time through sensors.The CC2430 module was used as the core of terminal measurement node,from which a wireless sensor network was established to realize wireless transmission and collection of data.The Field Programmable Gate Array(FPGA) main control system with Nios Ⅱ embedded soft-core processor was utilized to achieve the management of the entire system.Field experiments showed that the system could effectively collect environmental data,and had advantages of flexible networking,scalability and convenient portability,etc.
