低压电力线载波通信的集散控制数据交换研究

A distribution of low-voltage power line carrier communication control data exchange

低压电力线载波通信的集散控制数据交换平台,由若干集散控制接口单元组成,集散控制接口单元具有低压电力线载波通信功能及RS485总线通信功能,集散控制接口单元之间利用PL2102实现低压电力线载波通信,通过低压电力线完成上位机和下位机之间的数据交换。

Low-voltage power line carrier communication of distributed control data exchange platform is composed of a number of distributed control interface unit,low-voltage power line carrier communication function and RS485 bus communication functions of distributed control interface unit between the distributed control interface units use PL2102 to achieve low-voltage power line carrier communication through low-voltage power line to complete the exchange of data between the PC and the next bit machine.
