机房环境监控系统的设计与实现

Environment Monitoring System Design and Implementation

该文设计了一个机房环境监控系统。系统可以采集机房温度湿度,温度湿度超出设定范围向系统维护人员短信报警,并且可以远程视频监控。系统采用RS485总线型传感器网络实现机房温度、湿度的采集,以及监控主机与传感器的通信。温度湿度超出设定范围或者设备故障时,采用USB短信猫发送短信报警。使用PelcoD协议实现云台的转动和摄像机镜头的调节。远程视频监控采用C/S架构,选用了海康威视DS4004HC视频压缩卡将摄像机采集的原始数据压缩为H.264编码格式,用于录像保存和网络传输。

The design goals of this system is to achieve temperature and humidity monitoring and short message alarming, and enables realtime video surveillance through network in an unmanned computer room. A group of sensors attached on RS-485 bus are used to collect the temperature and humidity of the computer, and the RS-485 bus achieves the communications between host and sensors. When the temperature or humidity is beyond the scope that was set before or the equipment is breakdown, the USB SMS modem will send short message for alarming. Pelco D protocol is used to control the rotation of PTZ and adjust the camera. Remote video surveillance is developed on C/S structure. The hikvision DS4004HC camera video compression card is used to collect the original data and encode based on H.264 for video preservation and network transmission.
