摘　　要：为了实时监控服务器机房环境,保护服务器数据,以及预防可能出现的火灾,设计了一种基于FPGA的服务器机房环境监测及数据传输系统。系统以FPGA作为主控制器,使用温度传感器,一氧化碳传感器以及A/D转换模块,进行机房多个监控点的环境监测。FPGA将采集到的环境数据利用千兆以太网芯片,通过UDP传输协议,经由交换机转发至控制中心PC。同时,FPGA将各监测点的数据经过串口送至LCD串口屏显示。若环境数据异常,则触发声光报警。经测试,系统在机房环境下测量温度的误差不超过0.5℃,一氧化碳浓度的误差不超过5×10^-6,UDP传输速率可以达到800 Mb/s,满足系统环境异常监控与报警需求。To monitor the server room environment in real time,protect server data,and prevent possible fires.This paper designs an FPGA-based server room environment monitoring and data transmission system.The system uses FPGA as the main controller,and uses temperature sensor,carbon monoxide sensor and A/D conversion module to carry out environmental monitoring of multiple monitoring points in the equipment room.The FPGA collects the collected environmental data using a Gigabit Ethernet chip and forwards it to the Control Center PC via the UDP transport protocol.At the same time,the FPGA sends the data of each monitoring point to the LCD serial port screen through the serial port.If the environmental data is abnormal,an audible and visual alarm is triggered.After testing,the temperature error of the system in the equipment room environment does not exceed 0.5℃,the error of carbon monoxide concentration does not exceed 5×10^-6,and the UDP transmission rate can reach 800 Mb/s,which satisfies the abnormal monitoring and alarming requirements of the system environment.
