摘要随着单片机及ARM技术的广泛应用,以及芯片技术的不断发展, GPRS 通用分组无线业务在当前远程无线数据传输、遥测遥控中越来越受到人们的重视,所以,由此而开发设计的二次设备和产品得到极大的推广和应用。论述了基于WAV ECOM Q2406B 无线通讯模块、A RM7 LPC2138 微处理器的数据传输终端设计方案,并提供了部分硬件电路图、软件流程图及程序代码。
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。

Abstract Along with the wide application of single puter and ARM technique as well as the development of integrated chip technique GPRS general grouping wireless service is attached with more importance by people in the current data transmission 、metering and remote control . Therefore secondary product and quality goods developed and designed according to the techniques mentioned are obtaining enormous promotion and application. The data transmission terminal design based on Q2406B Module and ARM7LPC2138 are elaborated and partial hardware electric diagram .software flowchart and program code is provided.
For more decentralized distribution, place is not fixed, or the environment is bad monitoring site, puts forward a universal remote monitoring terminal of the design method. Terminal with modularization data acquisition function, and USES the ARM9 processor and Linux operating system, with Qt/Embedded write terminal application, make its have good human-machine interface, and analyze the data treatment, and a GPRS (general packet radio service) munication technology will be processed data sent to monitoring center, and stored in the database. The actual experiment proves that the terminal data processing speed, high precision, good
