预付费电表的工作原理,有什么益处?

Release date: View count:497

 

  现在很多地方都在使用预付费电表,先用电后付费的模式受到大家的欢迎。不过你了解过预付费电表的工作原理吗?预付费电表采用电子技术,实现信息传输功能,那么对我们的生活有什么益处?今天小编就详细介绍下;预付费电表的工作原理,有什么益处?

  一、预付费电表的工作原理

  采用电子技术,将负载电压和电流采样信号,经 16 位 A/D 转换成数字信号 处理,计算出电压、电流、功率,完成单相电能计量。同时, A/D 转换器生成 电量脉冲送到 CPU 计数通道。CPU 经过多种运算完成分时计量等多种管理工作 及信息传输功能。

  IC卡预付费电表断电原理,电表中的微控制器起到很大的重要,读取IC卡中的数据,当IC 卡里面的余额不足的时候,微控制器会给负荷控制开关下命令,内置开关断开,直接断电。

  预付费电表的工作原理,有什么益处?


  以上就是关于预付费电表的工作原理,如果您还有其他问题,可以随时咨询我们。
