Design And Implementation Of Environment Monitoring System For Small And Medium-sized Enterprise Computer Room Based On ZigBee

With the rapid development of information technology,companies begin to build their own data center and independent room,and higher standard of demand is required in terms of cost,environmental protection and energy saving.At present,most of computer room monitoring systems are expensive and are designed primarily for large-scale corporate clients.The system is dependent on artificial management to control the computer room,which leads to low specialized level and efficiency.Meanwhile the system is easy to make mistakes and shows retarded response toward alarmespecially in the event of emergency.Based on the analysis of the present status of monitoring system,this work investigates the data acquisition technology,data transmission technology and service program implementation,and completes the design and preliminary implementation of the computer room monitoring system in the background of theactual requirements of the environment monitoring system enterprise computer room in Hengyang.This system improves the degree of the monitoring automation as well as greatly reduces the potential security risks of computer room.Firstly,the monitoring test system of computer room is designed.The overall structure includes data acquisition layer,data layer and system application platform.We completed the collection,transmission,parsing,and saving functions for the environmental parameters and equipment of computer room,and reach the remote access function for the monitoring system of computer room.Secondly,the detailed design of monitoring test system of computer room is discussed.First,we study the main features of sensing equipment for monitoring test system,which includes temperature and humidity transmitter,power monitor,magnetic door sensors,water sensor,smoke alarm and video monitoring equipment;then comparative analysis the several commonly used short distance wireless communication technology,and realizing enterprise room scene real-time data interaction by using ZigBee wireless sensor network technology.Furthermore,we explore the architecture and protocol of ZigBee wireless sensor network,and complete the design of data transmission for ZigBee wireless sensor.Finally,in order to ensure the reliability and stability of data transmission,we complete design of communication protocol for computer room monitoring based on the research of computer communication technology.It can alert information in time and remind administrators deal with it,which greatly improves the stability and security of running system.The monitoring platform of this system is put up with the form of the Web browser;and it can play a role by registering the serial number of computer room monitoring equipment and connecting with computer monitoring system,capability of data storage,and realization of the remote visualization capability of enterprise computer room monitoring.The associative function of system design has preceded the practical application and achieved the expected goal.Furthermore,this system has good extension performance;on the premise of without redesigning the whole system,it can add or remove the type and amount of system equipment according to the customer requirement.
