摘要
随着数字信息技术的发展,通信技术主要应用在宽带通信网络和无线通信领域.GPRS的应用范围很广,可以用于开发互联网、移动性管理以及无线监控等方面.针对系统在远程监控上的应用方案,制定了系统实现的功能以及性能指标.根据给定的应用方案设计了无线监控数据传输系统的模型,并对各个环节的关键技术实现进行了研究.基于μC/OS-II实时操作系统针对GPRS模块通信编程,模拟量、数字量的采集任务编写以及触摸屏显示部分应用μC/GUI编程,通过GPRS网络使远程终端能接收到工业现场采集到的数据,从而达到监控的目的.在实现过程中,将终端的功能进行分类并安排到不同任务中实现,再利用操作系统对任务进行管理,具有良好的人机交互界面方便实用的同时,最终实现嵌入式远程监控系统的各种功能.
With the development of digital information technology in recent years, communication technology is main- ly concentrated in the field of the broadband communication network and mobile communication. GPRS can be widely applied to Internet developing, remote mobile management and wireless monitoring. A system applying GPRS for data transfer of wireless remote monitoring system is designed, and functions and capabilities of the system are also set out. This design applies μC/OS-Ⅱ real-time operating system to realize GPRS module communication programming, ana- logue/digital variables acquisition and μC/OS-Ⅱ programming for the display in the touch panel. Then remote terminal can receive the data collected from the industrial field, and implement the monitoring through the GPRS network. Dur- ing the process, the system can classify the functions of the terminal and assign to the different tasks which can be managed with the operating system. With the human-computer interface, this system is convenient and practical, and can realize various functions of the embedded remote monitoring system.
