机房监控系统设计

The Design of Equipment Room Monitor System

以机房监控系统的发展为背景,从监控模块、监控单元、监控中心三个方面介绍机房监控系统的构成;监控模块具有通用的模拟量输入接口、数字量输入、输出接口、远程拨号报警功能、对监控对象实现遥测、遥控等功能,监控模块的软件基于UCOS-II操作系统编写;监控单元具有定时轮询监控模块、保存历史数据、上传采样数据等功能,监控单元通过以太网和监控中心进行通讯;监控中心由PC机构成,监控中心软件基于Labview软件编写、不仅能够实现对监控对象的进行遥测、遥控等功能,而且可以查询历史采集数据,对数据进行统计分析。监控模块和监控单元的通信采用RS-485总线,协议采用《中华人民共和国信息产业部.YD/T1363.3-2005.通讯局(站)电源、空调及环境集中监控管理系统标准第三部分:前端智能设备协议》,该协议定义了具体的监控对象,以及一些常用的监测、监控的命令,同时预留了一部分自定义命令,可以使用户的使用更加简便。

In this paper, the development of the equipment room monitoring system for the background, from the monitoring module, control unit, control centers, introduced three aspects of the composition of the equipment room monitoring system.Monitoring module with a universal analog input interface, digital input and output interfaces, remote dial-up alarm function, the object of monitoring the achievement of telemetry, remote control functions, monitoring software module based on the preparation of UCOS-Ⅱ operating system. Monitoring Unit has regularly monitor polling module, the preservation of historical data, upload data features such as sampling, moni- toring and control unit via Ethernet communications centers. Control Center by the body into a PC, control center software based on LABVIEW software development, not only to achieve the target of the conduct of monitoring telemetry, remote control and other func- tions, and can learn about the history of collecting data for statistical analysis of data. Module and control unit to monitor the communications using RS-485 bus, an agreement of “People＇s Republic of China Min- istry of Information Industry. YD / T 1363.3-2005. Communications Authority （station） power supply, air-conditioning and environ- mental monitoring and management system standards focus on Part Ⅲ： intelligent front-end agreement ”, the agreement defines a spe- cific target of surveillance, as well as some commonly used to monitor, control commands, while reserved as part of custom orders, so that users can be more convenient to use.
