摘　　要：本文主要介绍数据中转器在远程环境监测系统中的重要应用，提出了一种基于μC／OS-Ⅱ嵌入式实时操作系统的数据中转器的软件模块设计方法。环境监测数据通过ZigBee网络经由汇聚节点传至数据中转器，再利用GPRS网络上传给服务器。数据中转器主要由ARM芯片LPC2148设计完成，负责采集数据的存储和上传，以及远程上位机服务器控制命令转发。本文所研究的软件设计方案具有实时性强，稳定可靠等优点。This paper mainly introduces the important application of data transfer device in remote environmental monitoring system, a method of software module design of the data transfer device based on the embedded real-time operating system of μC/OS-Ⅱ is presented. Firstly, the environmental monitoring data acquired is transferred to the sink node via ZigBee network, then the sink node sends this data to the data relay device, and finally the relay device uploads the data to the server by using GPRS network. The data relay device is mainly designed by means of ARM chip LPC2148, and it is responsible for storage and uploading of the acquired data, and also for retransmitting the control commands of the remote upper computer server. The above software design scheme is of advantages of high real-time, high stability and reliability.
