摘要
文中介绍了自动气象站数据采集器的工作原理及其设计方法。给出了嵌入式实时操作系统UC/OS_II在LPC2138上的移植方法,并以此为基础完成了自动气象站数据采集器的软硬件设计,利用Jennic5121模块完成数据采集器前端输入,同时引入GPRS模块实现采集器与远程业务中心的后端数据传递。该采集器具有实时性好、处理能力强、存储容量大及易扩展等特点。
The design method and theory of data collector for automatic weather station is described, and how to transplant real-time operating system UC/OS-II to processor LPC2138 also explained. Based on this platform,the hardware and software design of the collector is realized. The gigbee-based Jennic5121 module is used to realize the front input of the collector, while the GPRS module is introduced to realize data exchange with local data center. This real-time system is of strong processing capability and large memory storage, and also easy to extend.
