基于MQTT协议的数据中心动环系统数据采集器设计

Design of Data Collector for Power and Environment System in Data Center Based on MQTT

本文针对数据中心动环系统设备类型多、数据接口形式多样等特点,设计了一种数据中心动环系统设备前端数据采集的采集器,给出了模拟量采集接口、开关量输出接口、RS422接口、LVDS接口等典型硬件接口设计,以及数据采集器的软件系统架构。该数据采集器能够实现与配电、精密空调、温湿度、漏水等动环系统设备的数据采集功能,并通过MQTT协议实现与云平台的数据双向通信。

Aiming at the characteristics of many types of power and environment system equipment in data centers and various forms of data interfaces,this paper designs a collector for front-end data collection of power and environment system equipment in data centers.The design of typical hardware interfaces such as analog acquisition interface,switch output interface,RS422 interface and LVDS interface and software system architecture of data collector is given.Realize data acquisition of data collectors and power and environment system equipment such as power distribution,precision air conditioning,temperature and humidity,and water leakage,and data transmission with cloud platform through MQTT protocol.
