The Design for Smart Metering Based on Spread Spectrem Communications

介绍了一种基于扩频电力线通信技术的智能电表终端系统设计,该系统适用于低压配电网。利用AD7751芯片作为电量计量的主要部件,并将电能量参数通过SSCP300扩频载波通信模块传输到低压电力线,从而实现自动抄表。由于采用扩频通信技术,该系统能提高抗干扰能力,具有较高的实用价值。

A smart metering terminal design scheme based on spread spectrum communications is presented, which is applicable to low-voltage power network. The power and energy parameters are measured by AD7751 chip, transmitted by SSCP300 spread spectrum communications block over the low-voltage power line, which realizes automatic meter reading. In virtue of spread spectrum communications technology, the system enhances anti-interference with high practical applications value.
