摘要
介绍了一种自主研制的基于AT89C51单片机的自动抄表系统集中器,着重阐述了集中器的硬件组成、工作原理和软件设计方案.该集中器向下通过低压电力线作为信息载体,采集采集器和智能电表的数据,向上利用中国移动的GPRS网将计量数据发送至集抄网站和相关的供应管理部门.
A centralized unit of automatic meter reading system based on the AT89C51 single chip microcomputer is introduced. The hardware organization, working principle and software design scheme are emphasized. In this unit, low-voltage power line is used downwards as the information carrier to acquire the data from the collector and the intelligent power meters. And at the same time, the GPRS networks of China Mobile are used upwards in order to transmit the metering data to the relevant departments.
