  下图是一个硬件设计图:

  智能电表主要是由电子元器件构成,其工作原理是通过对用户供电电压和电流的实时采样,采用专用的电能表集成电路,对采样电压和电流信号进行处理,转换成与电能成正比的脉冲输出,最后通过单片机进行处理、控制,把脉冲显示为用电量并输出。通常把智能电表计量一度电时A/D转换器所发出的脉冲个数称之为脉冲常数,对于智能电能表来说,这是一个重要的常数,因为A/D转换器在单位时间内所发出脉冲个数的多少,将直接决定着该表计量的准确度。

  该系统是集微电子技术广东快乐十分、通讯技术和计算机技术于一体的高新产品,具有高可靠且安装简单等显著特点,广泛适用于城市及农村的电表、气表抄收、计费和监控。但由于电力线是给用电设备传送电能的,而不是用来传送数据的,所以电力线对数据传输有许多限制:(1)配电变压器对电力载波信号有阻隔作用,所以电力载波信号只能在一个配电变压器区域范围内传送;(2)不同信号耦合方式对电力载波信号损失不同;(3)电力线存在本身固有的脉冲干扰。另外电力线上的高削减、高噪声、高变形,使电力线成为一个不理想的通信媒介,但由于现代通信技术的发展,使电力线载波通信成为可能,其中数据信号的信噪比决定传输距离的远近。电力线载波通信的关键就是选用一个功能强大的电力线载波专用Modem芯片。

  智能电表的工作特点

  智能电表不只采用了电子集成电路的设计,再加上具有远传通信功能,可以与电脑联网并采用软件进行控制,因此与感应式电表相比,智能电表不管在性能还是操作功能上都具有很大的优势。

  • 万用表测量交流、直流电压,区分火线和零线,就是这么简单
  • 判断空开和漏保的好坏,电笔比万用表还好用,可算长见识了
  • 空开和漏保:A、B、C、D系列有什么区别?跟着老电工长长见识
  • 电线接头一受潮就漏电,电工胶布这样缠,就算泡水里也不会漏电
  • 插座一用电就跳闸,原来是零线共用惹的祸,老电工轻松解决了
