摘要
介绍自行开发的电力线载波自动抄表系统。该系统采用电力线传输数据 ,系统微机与单片机相配合 ,能够完成电表数据的全自动传输与系统维护 ,可通过电话网、双绞线以及电网构成一个庞大的可靠的通信网络。该系统的上位机以VisualFoxPro为开发平台 ,标准的接口与界面设计 ,使系统的维护简单易行 ;下位机采用 89C2 0 51完成底层通信协议的开发。整个系统组网便捷 ,施工方便。
The paper introduces a meter reader system which transmits datas via powerline. In this system, computer and single chip computer match each other and they can complete the telemeter datas transmitting and system maintenance automatically. In this system, the computer designs a development plate with Visal Foxpro, standard and friendly interface make the maintainance easliy. We adopt 89C2051 as the accessory ware to accomplish the development of the communication issue.
