摘要:低压电力线载波通信是一种利用低压电力线作为通信媒介的一种通信方式。低压电力
线载波通信具有无需布线、实施成本低、电力线路作为通信媒介覆盖范围广的优点。低压电
力线载波通信技术与物联网技术相结合,可以将许多终端组织为一个网络,终端采集各种数
据,并通过低压电力线载波通信的方式传输数据,将数据传输到控制平台或中间控制节点并
对其进行汇总和处理,通过控制平台可以向终端发送控制命令,控制终端完成控制操作。这
其中最重要的是完成终端之间的通信,使终端之间可以可靠的传输信息。本文的目的就是设
计完成一个低压电力线载波通信控制平台,实现载波通信平台之间可以通过低压电力线相互
传输数据。本文中通信平台之间的通信调制模式采用具有较强抗干扰能力的 FSK,控制芯片
采用具有低功耗、低成本、高性能优势的 Cortex-M3 单片机。最后设计了一个低压电力线载
波通信控制平台,经调试实现了模块终端之间的相互通信。

Abstract: Low voltage power line municatin is a mean munication that use low
voltage power line as munication voltage power line munication
has numerous advantages,such as no wiring,low cost of implement and the power line has a wide
range of covering as mucication bined with the of Things
technology,terminals can anized into work through the low voltage power line carrier
collecte various data and transport the data to the control platform or
the central control node with the mean of low voltage power line municaton to
assemble and process. The control platform can send mands to the terminals and
control the terminal plete the of the most important thing is to realize the
communication and transmit information reliably between purpose of this paper is
to design and realize munication and control platform of low voltage power line carrier
communication to realize transporting data reliably with low voltage power line carrier
communication between platforms. Modulation mode munication platforms in this paper is
FSK which has a stronger ability of anti-interference. The control chip is the Cortex-M3
microcontroller
