.

Whether the operation and maintenance staff of the data center can effectively control the operation of all points often has a huge impact on
the stable operation of the data center.

Data center power and environment monitoring system can supervise the power parameters and the status of the environment, unified collection and processing of real-time data, and in the first time the fault situation is reported, the system operation and alarm information for detailed records, to assist the computer room management personnel to conduct a comprehensive analysis of the operation of data center equipment, for each computer room environment hidden risks to judge
.

Keywords: data center; Power and environmental monitoring systems; 0 Introduction Driven by the rapid development of data business, the comprehensive functions of mathematical equipment and storage devices are also expanding, and the overall scale is gradually increasing, in order to ensure that the equipment can continue to maintain a stable state of operation, it is also necessary to pay attention to the implementation of equipment maintenance and management work to ensure that the data system can operate
stably and safely.

The formation of the centralized monitoring and management system of the power environment of the machine room can be said to be the inevitable development of society, which has the function of monitoring the operating state of the equipment, predicting the possible development of the fault, and solving it in a short period of time when encountering the fault, and also has the important functions of comprehensive management and unified regulation, so we need to continuously improve the operational stability of the power equipment to ensure the efficiency and effect of the operation of the data system, so as to effectively reduce the maintenance workload of personnel.
Improve the efficiency
of equipment operation.

1 Data center power and environmental monitoring system (1) System composition combined with the current national implementation of the relevant policies, the current environmental monitoring system used in the three-level cascade of basic hardware structure is usually composed of data management, display, collection and monitoring branch equipment combination
.

The monitoring object mainly involves power distribution equipment, power supply, temperature and humidity, fire protection, electronic access control and other infrastructure
.

Management functions typically include fault prediction management, comprehensive performance management, configuration management, security management, and so on[1].


The system shares the communication information of each branch system by means of computer database, communication, network sensors and other technologies, so as to ensure that the overall compatibility and scalability of the system can be fully exerted
.

(2) The system is deployed in those relatively large-scale data center computer rooms, and the three-level monitoring equipment, second-level monitoring equipment and terminal monitoring sensing equipment are installed, and the second-level monitoring equipment and terminal monitoring sensors
are installed for the small-scale site data computer room.

(C) the main features of the data center computer room power and environmental monitoring system monitoring system usually has the following functions: first of all, the real-time monitoring of the computer room can be implemented, and the images obtained by monitoring are saved by digital video recording, which is convenient
for subsequent investigation and consultation.

Secondly, it can be connected and coordinated with the existing access control management system in the computer room, and the seamless integration of the access control system can also be completed, so that the identity of the personnel entering and leaving the computer room can be checked and recorded, and the management efficiency and effect
of the computer room can be improved.

In addition, the use of audio and video surveillance can ensure that the computer room management personnel can check the situation of the computer room equipment and the computer room staff anytime and anywhere, and can also use the monitoring system to conduct video calls, which can also enhance the interaction while improving the monitoring work of the
computer room.

In addition, the environmental testing equipment set up in the system can timely supervise
the start-up adjustment system, lightning protection detection system, fresh air system, water leakage detection and machine room temperature and humidity installed in the machine room.

If the system releases a warning signal during the monitoring process, the alarm information can be formed immediately and the linkage function
of the early warning equipment can be turned on within the specified range.

In addition, it can be connected with the power distribution equipment in the computer room, and the duty management staff of the computer room can supervise and inspect the power configuration and the operation of each facility in the machine room with the help of the environmental monitoring system [2].


The management platform of the monitoring system has a strong user-friendliness, the operation is very convenient, and it also has the functions of
language prompts and Chinese character support.

When the alarm information is issued, the alarm signal will also appear in the performance effect of sound and optoelectronics, using e-mail, mobile phone short message to remind the staff, combined with the warning information can accurately determine
the location of the fault.

2 system requirements (1) real-time accuracy dynamic ring monitoring system is the direct manifestation of the basic environmental state of the data center, and the accuracy and timeliness of its data are very important
.

Usually in the construction process, it is necessary to carry out regular inspections of the system, and the real-time data is passed to the monitoring terminal for display, and it is also necessary to use the warning method to provide timely and accurate data for the maintenance staff, and the data can also be compared with the historical record for analysis, so as to effectively prevent the occurrence
of system failure.

(2) Scalability is comprehensively considered for many aspects such as fluctuations in the actual needs of construction, and the monitoring system also needs to have the performance of receiving people to expand [3].


First of all, expand the scope of monitoring, such as: when carrying out renovation work for some projects, monitoring and acquisition data systems or large-scale monitoring systems should be added on the basis of existing systems
.

Second, improve the level
of monitoring work.

In order to promote the improvement of the management level and bring a good practical experience to users, the general monitoring window of the control status situation should be added to the existing monitoring interface, so that the system can also be supervised and controlled
by the system operation communication state.

(3) When implementing the data center construction work, security needs to use the deployment of complete intelligent monitoring methods to supervise
the computer room.

For example, when carrying out system construction work, it is usually necessary to ensure that it has fire control measures and access control fading to give you linkage control capabilities, in the event of a fire, the system can lift the state of the access control on its own, so as to facilitate
the escape of trapped people and the implementation of rescue work of fire personnel.
