摘　　要：针对目前机房集中监控系统产生的数据量大,且通用数据采集器功能单一、实时性差的问题,提出一款以京微雅阁SoC系列FPGA为核心设计实现的多功能一体化数据采集系统.通过分析通用数据采集器实时传输的难点,系统采用了软硬协同的设计方法,由Cortex M3实现系统的网络协议及数据调度算法,并利用可编程逻辑对异步串口及以太网接口进行硬件加速.它能够实现同时对多个接口进行数据采集,并通过以太网实时传输.实际系统的运行测试,验证了该平台的可靠性和实时性,并且系统具有较高的数据吞吐能力和灵活的扩展性.In current data acquisition system,data produced by the concentrated monitor system is huge,the function of general data acquisition equipment is single,and the real-time performance is bad.In this paper,an integrated multi-function data acquisition system is proposed based on Capital Microelectronics SoC series FPGA.By analyzing the difficulties of real-time transmission in general data acquisition equipment,a methodology of hardware-software co-design method is applied in the whole system,in which the network protocol and data scheduling algorithm are implemented in Cortex M3,and the programmable logic is used to accelerate the asynchronous serial interfaces and Ethernet interface.The system is used to collect data from multiple interfaces,and implement real-time transmission in the Ethernet.The running test in the real system shows that the platform is reliable and has high real-time performance.It also has a high data throughput and flexible expansibility.
