For another example, the mode switching of the heating, ventilating and cooling system needs to follow the design requirements, and the actual operation is often partial load operation, for example, the original design IT load is 5000kW, the temperature set point for switching to natural cooling is 2 ℃ of outdoor wet bulb temperature, and in the actual operation, because IT equipment is deployed in stages, the first-stage IT load is only 2000kW, the capacity of the cooling tower can completely realize that natural cooling starts when the outdoor wet bulb temperature is 4 ℃, and at the moment, the management system can prompt operation and maintenance personnel to modify the set value for starting natural cooling, so that the natural cooling time is prolonged, and the purposes of saving energy, reducing PUE and saving electricity charge are achieved. The management system provides optimized operation suggestions for operation and maintenance personnel in time on the basis of analyzing meteorological data, IT loads, capacity and characteristics of refrigeration equipment, and therefore energy conservation and reliable operation are achieved. After data analysis, the management platform can prompt active maintenance of equipment components and system components, optimization of operation and maintenance strategies and the like on the operation terminal.

Fig. 3 is a basic structure of the first embodiment, and fig. 4 is a basic structure of the second embodiment.

The operation and maintenance management device 80 may be a computing device with a human-computer interaction function, such as a computer with a display screen, an intelligent mobile terminal, and the like. The comprehensive data of the monitoring management device 10 can be acquired through man-machine interaction, the operation and maintenance related data are transmitted to the monitoring management device 10, the running state information of the monitoring management device 10 is displayed, and reference is provided for the man-machine interaction of workers.

Here, it should be noted that the above many management items are not all required, and one, two, or more kinds of management items may be freely set according to the specific situation of the data center.

The alarm management is that the site facilities of the data center are numerous, have different functions and different old and new, so that the alarm is frequently generated, and the alarm management function can set alarm attributes of different levels according to different data centers.

The change management means that the new generation Ptas system of the Intel server can output the data of the inlet air temperature and the power consumption of the server, when the server is ready to be put on the shelf or is running, the total power consumption (electric quantity) of the existing IT server can be compared with the capacity of high-voltage direct current, the capacity of a transformer and the capacity of refrigeration equipment, and the number of servers which can be allowed to be put on the shelf is calculated and analyzed. The annual power consumption (electricity) data of the server should be analyzed with the trend of time.

The goal of knowledge base management is to establish and continuously improve knowledge bases such as technical specifications of site facilities, spare parts, maintenance manuals and the like, namely, the technical specifications of the site facilities, the types and quantity of the spare parts, the maintenance manuals and the like can be retrieved by clicking a knowledge base management system.

The supplier management aims to establish a perfect database for counting the operation failure times of the equipment, operation and maintenance processes and manuals and brand management, and reduce the possibility of service interruption caused by incomplete operation and maintenance related databases and misoperation of the suppliers. The field facility operation and maintenance department usually adopts outsourcing human resources to provide technical services, and the analysis data in the industry indicates that more than 60% of accidents which seriously affect the operation of the business are caused by human operation errors, and most of the accidents are caused by outsourcing personnel. The perfect supplier management system and the on-duty training plan can effectively reduce the accidents caused by human operation errors. When a right button of a mouse clicks a certain electromechanical device, the right button should have data such as a device name and a serial number, a device brand, a capacity parameter and the like, when a left button clicks the certain electromechanical device, the left button should have branch options such as a two-dimensional code (optional), a maintenance flow and a manual, failure accumulation times and whether the failure times in one year are more than 3 times, and the options are clicked respectively to obtain related data; the mobile phone scans the two-dimensional code to obtain the maintenance flow and the manual of the equipment.

The work order management requires that site facilities of the data center have unique numbers, and the site numbers of the facilities are consistent with the numbers in the management platform system. Active maintenance of equipment of different systems of data center site infrastructure is the most important means for ensuring reliable operation of the systems. Through regular active maintenance, the equipment failure probability can be effectively reduced, and the availability of the data center is improved. The work order system should define the maintenance period requirements of the main site facilities, namely daily inspection, weekly inspection, monthly maintenance, quarterly maintenance, semi-annual maintenance and annual maintenance; critical operation periods should also be defined, i.e. which periods are suitable for maintenance work and which periods are not. The work order system should make a specific schedule that each device needs to be periodically maintained, can automatically generate a work order according to operation and maintenance requirements, and tracks the whole maintenance process. Proactive maintenance tasks that should be performed by a site facility on a weekly, monthly, quarterly, semi-annual, annual basis are exemplified as follows.
