摘要
基于嵌入式MODEM的远程数据采集系统在检测和控制领域具有广阔的应用前景。阐述了采用Philips89C58单片机通过AT命令集控制嵌入式MODEM,通过PSTN进行数据通讯,以实现远程数据采集的软、硬件设计思想及实现方案,该系统可以实现远程控制中心和监测控制站点的可靠、高速率的通讯。
The remote data acquisition system constructed on the embedded MODEM has a wide application prospects in the filed of testing and control. The paper mainly introduces the techniques of how to use Philips89C58 Single Chip Processor to control the embedded MODEM by AT orders and how to conduct digital communication through PSTN to put the design concepts into effect. This system can realize the reliable and high-speed communication in the remote control center and monitoring control stations.
