摘要
本文研究开发了一套基于GPRS技术的无线数据采集系统,远端数据采集模块将传感器的输出信号进行模数转换,通过串行接口驱动无线modem经GPRS网络将数据发送到Internet上的远程监控中心,并完成数据的存储和显示。本文从硬件和软件两方面描述了系统的设计及实现方法。这种新型的无线数据采集系统非常适合于在边远地区或可移动系统中实现无线的数据采集和监控。
In this paper, a wireless data acquisition system based on GPRS technology is presented. The analog signals of sensors are digitized by remote sampling block. Then wireless modem, which is drovod through serial interface, transmitted the acquired data to the remote monitoring center with the help of GPRS network. The remote monitoring center is responsible for data displaying and saving. The design and implement method of its hardware and software system is demonstrated. The new type of wireless data acquisition system is extremely fit for the applications of sampling and monitoring system, which lies at remote area or mobile objects.
