基于K60与FPGA的电子式互感器采集单元的实现

文中设计的采集单元是电子互感器与合并单元（MU）数字接口的重要组成部分，主要用于把电子互感器采集到的瞬时原始电信号经转换后发送给过程层的合并单元。研究了电子式互感器的工作原理，提出了一种基于飞思卡尔K60与现场可编程门阵列（FPGA）为硬件平台的采集单元来实现此接口的新方法。该采集单元主要完成信号调理、积分、模数转换、编码等功能，最后以标准FT3帧格式的形式通过光纤发送出去。

Realization of collector unit on electronic transformer based on K60 and FPGA

In this paper, the collector unit of the design is an important component of the digital interface between electronic transformer and merging unit （MU）, served in sending the convertect instantaneous and original data which collected by electronic transformer to merging unit. It presents the working principle of the electronic transformer and gives out a new method to implement this interface through using the collector unit which uses the hardware platform based on the K60 of freescale and the field programmable gate array （FPGA） to realize. This collector unit mainly completes the signal adjusting, integration, A/D conversion, encoding and so on, finally in the form of standard FT3 frame format through optical fiber to send out.
