振动信号采集及网络化传输关键技术的FPGA实现

Key Technical Study of Mechanical Vibration Signals Collection & Network Transmission Based on FPGA

介绍了一种基于FPGA(现场可编程门阵列)的多路转换模拟通道寻址技术的变频率采样方法,针对机械振动信号数据量较大、实时性要求较高的特点,提出了基于FPGA来实现的以太网传输方式。把数据采集控制、数据缓存、数据封装以及数据传输控制都集成在一块FPGA芯片里,并通过硬件描述语言VHDL来实现。

This paper propose a way to sample vibration signal with adjustable fi＇equeney which based on multiplexed conversion channel addressing in internal FPGA（Field Programmable Gate Array）. Also addressed mechanical vibration signals features of large volume of data requirement of real-time, proposed a FPGA-based Ethernet to achieve the means of transmission. The design elaborated in this paper integrated control of data collection, storage, packaging and transmission control in a single FPGA chip, and through hardware description language VHDL to achieve.
