基于ZigBee和C#的农田数据采集系统

针对农田数据采集系统有线传输方式常受到地形、安装环境等限制问题,提出了一种基于ZigBee数据采集传输系统.采用CC2530芯片为主搭建无线传感器网络,终端和协调器采用半开源的Z-Stack协议栈进行程序开发,上位机基于Visio Studio 2015平台采用C#语言进行软件开发,并配合ACCESS数据库,共同实现了系统的远程检测与本地保存和动态显示.在玉米试验田进行实地测试,终端按采集需要暂时设定为每间隔1 h采集一次数据,其余时间处于休眠状态.经计算,终端预计工作时间为100 d左右;且经过测试,终端与协调器的有效传输距离能达到80 m,数据传输有效率达92%.结果表明:该系统具有低功耗、低成本、系统运行稳定、可扩展性强等特点,满足农业信息化的需求.

Farmland data acquisition system based on ZigBee and C#

Aiming at restriction problem of landform and settle environment on wired transmission,a data acquisition and transmission system based on ZigBee is proposed. The CPU of the wireless sensor networks (WSNs )is on the basis of CC2530,half-open-sourced Z-Stack protocol stack is adopted in the program development of the terminal and coordinator. The upper computer software is also developed with C#based on Visio Studio 2015 and ACCESS database to achieve remote monitoring,local data-saving and dynamic display. Field tests on a corn plot are carried out,the terminal is set to collect data every 1 h,and hibernate in the rest of time. By calculation,terminal estimated working time is about 100 days;the efficient transmitting distance between terminal and coordinators is 80m,and the efficiency of data transmitting reaches 92%. Results show that system can content the requirements of agricultural information,which has features of low power consumption,low cost, stability and scalability.
