基于ARM和GPRS的远程监测终端设计

针对分布比较分散,场所不固定,或是环境比较恶劣的监测现场,提出了一种通用的远程监测终端的设计方法。终端具有模块化的数据采集功能,并采用ARM9处理器和Linux操作系统,用Qt/Embedded编写终端应用程序,使其具有良好的人机交互界面,并对数据进行分析处理,采用GPRS（通用无线分组业务）无线通信技术将处理过的数据发往监测中心,存入数据库。实际实验证明,该终端数据处理速度快,精度高,实时性好,可以满足一般监测现场的要求。

Design of remote monitoring terminal based on ARM and GPRS

This paper proposed a design method of common remote monitoring terminal for the monitoring of the distributed,no fixed,or relatively harsh environment site.The terminal has modular data acquisition performance and it is based on ARM9 processor and Linux operating system,the application program is written with Qt / Embedded.It has good interactive interface,and can process the data flexibly,the data will be sent to the monitoring center and stored in the database through the wireless communication technology of GPRS（General Packet Radio Service）.Theexperiments show that the terminal has high data processing speed,high precision,real time property,and can meet the general monitoring site requirements.
