中文摘要:

为解决无极性RS485通信方案电能表在现场工作时发生的组网通信问题，本文首先对智能电能表中应用的有极性RS485通信原理进行简单介绍，并指出无极性RS485相对于有极性RS485在原理上的改进措施。结合通信方式为无极性RS485的智能电能表配合老款集中器在现场应用中容易出现的组网问题，分析部分电能表应用的无极性RS485在原理设计上的不足，并提出改进方案，保证现场工作的智能电能表的RS485通信由原来的有极性方式向无极性方式的顺利过渡。

英文摘要:

To solve the communication failure about intelligent watt-hour meter with non-polar communication solution.In this paper, the RS485 communication mode is introducted for the application of intelligent watt-hour meter, pointing out the improvement plan in principle between non-polar RS485 with the polar RS485.Combined with non-polar RS485 communication mode for the common fault of the intelligent watt-hour meter in field application situation, analysis of non-polar RS485 on the principle of design, and puts forward the solution.Ensure that work at the site of the intelligent watt-hour meter has Smooth transition between the original polarity interface RS485 to the manner of non-polar.
