【摘要】 基于ARM和GPRS的无线数据传输模块通过串口与现场测控装置进行信息交互,通过GPRS模块利用GPRS网络服务与监控中心进行信息交互。因此,该类模块可广泛用于远程监控系统中。为方便实现TCP/IP网络协议,模块设计时采用了高性能ARM处理器(S3C44B0X)并移植了嵌入式操作系统μC/OS-II。文中主要介绍了模块的硬件和软件设计方法,给出了模块的测试方法和测试结果。更多还原

【Abstract】 The information between the module, which is designed based on ARM and GPRS, and the intelligent device is transmitted by the serial port of the module. And the data communications between the module and the monitor center are realized by the GPRS wireless module. So the module discussed can be used in remote monitor systems and so on. To realize the network protocols such as TCP/IP conveniently the high-performance microprocessor S3C44B0X is used and the embedded operation system μC/OS-II is ported to it. The design methods of the hardware and software of the module are discussed and the way to test the module and its testing result are introduced.更多还原
