摘要
本文根据工业系统的需求,提出了一种结合嵌入式技术和GPRS无线通信技术的远程数据传输终端方案。该终端以ARMS3C44B0X微处理器为硬件平台,以μC/OS-Ⅱ为操作系统,采用了μC/OS-Ⅱ的多任务的软件设计方法,提高了系统的实时性和可靠性。该终端内嵌TCP/IP协议,可以通过GPRS网络连接到互联网,数据传输实时性强,为用户提供透明的数据传输通道。最终在实验室环境下进行了测试,达到了预期透明传输数据的目标。
According to the present industrial system＇s demand, this paper proposes one kind plan of Long range data transmission terminal unifying the embedded technology and GPRS wireless communication technology. This terminal takes the ARM S3CA4B0X microprocessor as the hardware platform and μC/OS-Ⅱ as the operating system, and uses the multi-task software design method of μC/OS-Ⅱ, which simplifis the design of application procedure, and enhances the system＇s timeliness and reliability. In this terminal inlays the TCP/IP agreement, and connections Internet through the GPRS network, data transmission is timely, which provides the transparent data-transmission channel for the user. The test has been carried on finally under the laboratory environment, and has achieved the goal of anticipated transparent transmission data.
