摘    要:介绍了一款多功能电力监测仪,采集参数涵盖了除谐波以外的所有电网参数,监测仪嵌入CDMA通讯模块,利用模块的短信收发功能,将各种采集数据做远程传输。查询采集数据的设备可以是固定的电脑,也可以是一部手机,不受距离和地区限制,非常灵活方便。为了最大限度地降低运行费用,还可将单台监测仪作为主机,通过RS485总线连接若干台监测仪作为子机,组成电力采集网络,使多台监测仪共用一块CDMA通讯模块。这款电力监测仪已顺利通过各项EMC性能测试,并批量投放市场。

关 键 词:485总线  CDMA  AT指令  多功能电力监测仪

Abstract:This article describes a multifunctional power monitor,and gathered all electric network parameters except harmonic parameters.The monitor embedded CDMA communication modules;sending and receiving short messages,remote transfer the collection data.For checking data device can be fixed the computer or a mobile phone,no limited with area and distance,very flexible and convenient.In order to maximize the reduction in the running costs,single monitor as host,can be connected with several monitor as subset,by RS485 bus,build a power collection network,the more monitor share a piece of CDMA communication modules.This kind of power monitor has been successfully passing the performance testing and mass market.
Keywords:485BUS  code division multiple access(CDMA)  AT command  multifunctional power monitor
