摘要
介绍利用RS485总线实现智能化社区远程自动抄表系统的结构和硬件电路设计方法。系统以RS485总线构成的通信网络为基础,以集中控制器为核心,控制抄读一栋楼内的各个住户的用电量,每栋楼集中抄读到的电量数据通过电话线远程传输到社区管理中心,实现对社区各住户远程自动抄表功能。该系统结构灵活实用,易扩展,很容易应用到社区“三表”的自动抄表系统中。
The system structure and design method of hardware circuit the of remote auto-reading-meter system with RS-485 Bus are introduced in intellectualized community. In the system, The basis of data communication is RS-485 network, Central control equipment is the nucleus, gathering electrical amperage of users in a building. The electrical amperage of every central controller gathering is transmitted to data center of intellectualized community by RS\|485 Bus, in this way the function of remote auto-reading-meter in community is realized. Practical application shows that the system has satisfactorily flexibility and practicality. So it can be easily expanded to Auto-reading-meter system of 'three meters'.
