摘 要: | 针对电力系统中需要实时监测电量信息,选用具有RS-485串行通讯和标准Modbus协议的智能电力网络仪表,采用星型结构的RS-485总线实现多从站、长距离通讯.实验中采用Modbus协议通过RS-485总线与上位机计算机中的组态软件对智能电力网络仪表进行远程通讯监测,将各电力网络仪表的电量信息以数据表格的形式在组态软件的数据采集窗口中显示.将所采集到的符合IEEE 754标准的数据进行分析计算转换为浮点数格式,实现智能电力网络仪表监测分析.

Abstract: | We choosed intelligent power network meters with RS-485 serial communication and standard Modbus agree ment to collect real-time information,and used the star structure of RS-485 bus to achieve multi-slave station and long-distance communication.The experiment of power network intelligent meters used Modbus agreement and RS-485 bus to communicate with configuration software in computer remote monitoring.In order to analyse real-time monitoring results,all the information of power network meters was displayd in the configuration software data-acquisition-window in table.Then the collected data up to the IEEE 754 standard were transformed into floating-point number format to realize the monitoring analysis of intelligent power network meters. |
