多种通信功能农田数据采集传输装置的研制

Development of the Embedded Device for Farmland Data Collecting and Tansmitting with Tree Wys

以影响农作物生长较大的因素:温度、湿度、光照强度作为研究对象,研制了一种具有多种通信功能的嵌入式数据采集传输装置。该装置可通过短信息(GSM)、以太网、本地存储(CF卡)3种方式与数据监控中心通讯。同时,给出了硬件原理图,移植了μC/OS-II实时操作系统和LwIP协议栈,详细分析了任务的划分和任务间通信。实验证明,该系统实时性强、可靠性高。

The research is focused on the factors which affect the plants markedly such as temperature、humidity and intensity of illumination,we develop a kind of set for data collecting and transmitting with three ways. The paper gives the illustrative diagram of hardware,ports the real Time operating system μC/OS-II and the protocol stack LwIP,analyzes the partition and communications of the tasks. Experiment testifies that this system has strong real-time capabilities and high reliability.
