摘要

本文包括基于射频的传感器节点设计，用于测量关键区域，并远程收集有用的环境数据，如污染物、雨
量、温度和湿度。考虑到在调查区域的访问不良或不存在，在指定位置张贴足够的配备RF的传感器节点，以收集
数据，由用作控制和处理单元的微控制器处理。处理单元还处理来自用户的请求并通过SMS发送反馈；这些请求和
相关反馈通过GSM模块传输。当检测到设置的参数时，也会处理来自传感器的数据，并自动发送相应的SMS警报或
呼叫。除了在少数系统中使用基于GSM和微控制器的处理单元之外，这里提出的系统还使用基于RF的传感器节点
进行局域数据传感。这允许对给定位置进行实时调查。原型成功开发并测试了特定的COTS组件，如用于局域网通
信的RF TX/RX433MHz、用于将数据格式化为数字的PLL4046、用于远程通信的GSM SIM900以及用于数据处理的
PIC16F877微控制器。
