| 中文摘要:针对智能电能表检测装置中串行载波通信的不足，提出了一种并行载波通讯的方法。该方法将智能电能表和抄控器串行连接，组成串联抄表电路，各个表位之间抄表电路为多路并行电路，并引入两级衰减电路，使其组成能够衰减电路中的载波信号的隔离滤波器，从而有效地避免载波信号对其他表位形成串扰。通过实验，本方法可以同时实现多个电能表的载波通信，从而节约了读表时间，提高了读表效率。 |

| Abstract:Aiming at the shortcomings of serial communication of smart electricity meters，a method of parallel carrier communication is proposed. The method connects the smart electricity meter to the copy controller to form a series meter reading circuit，two level attenuating circuit is introduced to form an isolation filter capable of attenuating the carrier signal in the circuit，Thereby effectively avoiding the carrier signal to form crosstalk on the other epitopes. The experiment analysis shows，this method can realize the carrier communication of several energy meters at the same time，which saves the time of reading the meter and improves the efficiency of reading meter. |
