摘要
以嵌入式微控制器为核心 ,将传感器网络收集来的数据通过无线电发射机发送到远程接收机 ,从而实现远程数据采集。系统的优势是充分利用了短波无线链路资源 ,适合于工作在无人区等场合。以ARM7为控制器 ,功耗小 ,性能稳定 ,维护方便 ;通信方式采用串口通信 ,连接线少 ,实现相对简单。系统设计主要应用嵌入式 μCLinux系统设计、无线电发射、调制解调器等方面的知识 ,文中给出了调制解调器拨号协议、系统原理和软件流程等。
Using an embedded micro-controller as its key element, the introduced system collects data by a wireless sensor network and transmits the data to the remote receiver by wireless transceiver. Thus a system of remote data collection is formed. Some key technologies have been used in this system such as embedded μClinux design, wireless transceiver and modem. The system structure diagram and software flow chart are presented.
