摘要
设计实现了一种基于电力线载波通信技术(PLC)的配电变压器监测终端(TTU)通信模块。模块选用SGS-THOMSON公司的电力线载波芯片ST7538对电力线载波信号进行调制解调。通信模块的主控制器采用高性能处理芯片ARM芯片做为核心单元,对ST7538进行通信控制。此模块的通信格式参照DNP3.0通信规约进行设置,对其软件设计进行了详细介绍。
Design and implement a communication module of distribution transformer monitoring terminal unit （ITU） based on the power line cartier communication technology. Through the power line carrier chip analysis and comparison, choose the power line carrier chip ST7538 of SGS-THOMSON to modem power line carrier signals. The communication module use the high-performance processing chip-ARM chip as the main controller, to control the ST7538 ＇s communication. The communication format of this module reference DNP3.0 communication protocol, and its software design is described in detail.
