摘要
本文提出了基于无线传感器网络和TD-SCDMA传输的森林土壤湿度检测方案,分析了采集系统的工作原理和整体方案,设计了采集系统各个部分的硬件组成。同时分析了土壤湿度不同采集方法的优缺点,列出了土壤含水量的数学表达式。最后介绍了土壤传感器网络节点的分布规则和计算方法。
Gathering method of forest soil humidity based on wireless sensor network and TD-SCDMA was proposed. The operating principle and the composition of hardware of the system were presented. The advantages and disadvantages of several soil humidity gathering methods were also analyzed. The mathematic representation of soil moisture was given. Lastly, the distributing rule and calculation method of the nodes of soil wireless sensor network were presented.
