Hardware Design of Video supervisory System based on FPGA

本文主要介绍了基于FPGA的视频监控主机系统硬件设计中的多路视频采集电路、USB接口电路、串口转换及通信电路、EEPROM电路等电路的设计,单片机和FPGA的并行使用,可以使数据传输更加协调,提高系统可靠性。该硬件系统能够实现视频信息的存储及传输,报警信息自动存储,USB信息拷贝,允许多路同时报警及远距离控制云台等功能,使得监控控制系统工作效率有了进一步的提高。

In this article, the hardware design of the multi-channel signal collection circuit, USB circuit, COM transformation circuit and its communication circuit, EEPROM circuit based on FPGA is introduced in the video supervisory system. The mode of parallel communication between FPGA and SCM can make the data transformation more harmonious and enhance the reliability of the system. The system can transmit the video signal and save it, store the alerting signal automatically, read and write signal through USB ports, give an alarm through multi-channels and control the remote engineering parts of the system. The design promotes the efficiency of the supervisory system greatly.
