Multi-place machine room air conditioner centralized control system and control method thereof

Abstract

The invention relates to a multi-place machine room air conditioner centralized control system and a control method thereof, and belongs to the technical field of distributed control systems. The multi-place machine room air conditioner centralized control system comprises a host, the host is connected with configuration gateways in a machine room A... a machine room N through a communication bus, each machine room comprises a configuration gateway, the configuration gateways are connected with a signal acquisition module through the communication bus, the input side of the signal acquisition module is connected with a UPS power supply and a field sensor through a field signal line, and the output side of the signal acquisition module is connected with an air conditioner switch through the field signal line. Data in machine rooms in different regions are collected, processed and transmitted by adopting a communication bus protocol, and finally the data are visually displayed on a host. According to the multi-place machine room air conditioner centralized control system provided by the invention, real-time monitoring of each data of each place can be realized on the host, picture configuration and alarm threshold setting can be carried out according to actual conditions, the energy management and control level is improved to a great extent, and meanwhile, the system has great significance in energy conservation, emission reduction and elimination of dangerous hidden dangers.

Description

technical field [0001] The invention relates to a centralized control system and a control method for air conditioners in multiple computer rooms, and belongs to the technical field of distributed control systems. Background technique [0002] According to the "State Grid Corporation of Information Computer Room Design and Construction Specifications", the temperature requirement of the main computer room is 23°C ± 1°C when the mainframes of the A-level and B-level computer rooms are turned on, and the temperature requirement of the mainframe room is 20°C~26°C when the mainframes of the C-level computer rooms are turned on. The temperature of the main computer room in the D-class computer room is required to be 18°C~28°C when the host machine is turned on, and the temperature of the mainframe room is 5~35°C when it is shut down. There are also corresponding regulations for humidity. [0003] As the State Grid city power supply company, county power supply company and other ...

AI Technical Summary

Problems solved by technology

[0003] As the State Grid city power supply company, county power supply company and other units, the power supply, temperature, and humidity of the information computer room play an extremely important role in the normal operation of the computer room. Once a problem occurs in the information computer room, it will not only affect the safe supply of electricity, but also give Residential and business use of electricity causes losses, and there may be safety accidents

[0004] At present, the power supply of the computer room basically adopts UPS regulated power supply, and at the same time, air-conditioning is used for cooling, which effectively guarantees the stability of the power supply voltage in the computer room and the requirements for the temperature and humidity of the computer room environment in the "State Grid Corporation of Information Computer Room Design and Construction Specifications" , but in actual use, it is impossible for the computer room to be on duty all the time. When the UPS power supply voltage is abnormal or the temperature control effect of the computer room air conditioner is not ideal, the problem cannot be found in time, and it will not be discovered until there is a problem in the computer room.

At the same time, the existing control method is not intuitive, and cannot detect and deal with problems in a timely manner. Especially for the existing nearly 20 computer rooms that are not in the same location, the monitoring and control are particularly unsatisfactory, and there is a serious lag in the discovery of hidden dangers and the treatment of problems. sex

Moreover, when the actual environment is low, there is a great waste of energy if the air conditioner is always on.
