| More and more computer rooms are being built more with the wide use ofcomputers. Conditioner for computer room must work reliably every minute to keep thecomputer’s environment temperature in normal and required condition. Oncebreakdown happens to the computer room conditioner, computer system will be affectedand grave consequences will be led to. Now many computer rooms’ mangers have to beon duty in the whole day and tour computer conditioners regularly, which not onlyburdened the managers but also caused the accidents and undefined responsibilitiesbecause of malfunction unfound and excluded. So a centralized monitoring andmanagement is necessary to computer conditioners used in large computer rooms.In view of the present situation of the management of computer room airconditioning equipment, centralized monitoring system in this paper, the computer roomair conditioning of the research situation and application status at home and abroad wereanalyzed, and based on the analysis of the specific project requirements, designed acomputer room precision air conditioning centralized monitoring system. For each layeradopts hierarchical control method, software development, integrated control room airconditioners and independent control function. After the test and actual application ofcentralized monitoring system, verify the feasibility of the monitoring system designand scientific nature.This paper mainly completed the following work:1, the detailed analysis of the specific needs of the centralized monitoring room airconditioning system, puts forward a kind of air conditioning monitoring system basedon distributed multi-layer CPU structure form design scheme, and according to the ideaof hierarchical control centralized monitoring system can be divided into: computerroom precision air conditioning control layer, centralized control and monitoringmanagement.2, the room air conditioning control system hardware structure configuration, usingthe profibus-dp protocol to form a monitoring network; And on the basis of the demandof the system, through the software programming of PLC and PC monitoring softwareconfiguration of the specific function of each control layer in detail design.3, centralized monitoring system for functional testing, performance testing, and inspection of actual operation, indicates that the centralized monitoring room precisionair conditioning system design scheme has high practicability, scientific management ofcomputer room air conditioning provides a good platform.The centralized monitoring system to achieve more precise control and centralizedcontrol room air conditioning, on the premise of meet the control accuracy to ensureroom environment is stable, reliable and meet the demand of computer relatedequipment to run, to the management of computer room air conditioning maintenancebring great convenience. At the same time, the project for other management ofcomputer room equipment maintenance provide a reference. |
