利用移动公网、电话公网实现远程通信如POS机,各研究领域利用单片机远程数据采集后到计算机进行处理分析。单片机与计算机远程通信技术在现实中应用非常广泛。文中以无线POS机为例,通过介绍无线POS机的系统构成和设计思路,采用的软硬件来探究单片机与计算机远程通信的实现。 The use of mobile public network, telephone public network to achieve long-distance communications such as POS machines, the use of single-chip remote data acquisition to the computer processing analysis. Microcontroller and computer remote communication technology is widely used in reality. In this paper, the wireless POS machine as an example, by introducing the wireless POS system configuration and design ideas, the use of hardware and software to explore the SCM and computer remote communications.
