研究一种基于SOPC技术的列车分布式环境异物入侵监测系统,系统将视频数据的采集、处理与传输集成到单片FPGA上,采集和处理部分用硬件描述语言编写成硬件模块,作为外设挂到NiosⅡ系统中,传输部分采用以太网接口IP核,构建成SOPC系统去实现异物入侵监测系统。同时,用户可以方便地添加IP核来扩展系统功能。最后,在Altera公司的DE2开发平台上进行验证,达到了设计的要求。 This paper studies a train distributed environment intrusion detection system based on SOPC technology. The system integrates video data acquisition, processing and transmission into a single FPGA. The acquisition and processing part is written in hardware description language into hardware module. To Nios Ⅱ system, the transmission part of the Ethernet interface using IP core, built into SOPC system to achieve foreign body intrusion monitoring system. At the same time, users can easily add IP cores to expand system capabilities. Finally, the Altera’s DE2 development platform to verify, meet the design requirements.
