摘要
介绍一种多通道同步采集、长距离级联传输的低功耗、小型化采集传输系统。系统的采集传输部分主要以现场可编程逻辑门阵列(Field Programmable Gate Array,FPGA)为主控单元,结合外围控制电路将模拟信号采集打包后,经多点低电压差分信号(Multipoint low Voltage Differential Signaling,MLVDS)总线传输至桥接板转换为百兆以太网后上传至上位机进行数据分析与处理。采用此采集传输系统方案设计,能有效地完成多路通道的同步采集传输,实现接收阵小型化设计。
This paper introduces a low power consumption and miniaturized acquisition and transmission system with multi-channel synchronous acquisition and long-distance cascade transmission.The acquisition and transmission part of the system mainly uses Field Programmable Gate Array(FPGA)as the main control unit,combines with the peripheral control circuit to collect and package the analog signal,and then transmits it to the bridge board via Multipoint low Voltage Differential Signaling(MLVDS)bus,converts it to a 100 Gigabit Ethernet,and then uploads it to the upper computer for data analysis and processing.The design of the acquisition and transmission system can effectively complete the synchronous acquisition and transmission of multiple channels and realize the miniaturization design of the receiving array.
