Study Of Energy Consumption Monitoring And Management Platform Of Ventilation And Air Conditioning System

The energy consumption of buildings accounts for about 1/3 of the total energy consumption of the whole society.The proportion and absolute value of energy consumption of buildings are very high.For large-scale public buildings,the ventilation and airconditioning system accounts for the highest proportion of energy consumption.Ventilation and air-conditioning systems are large energy consumption systems for large-scale public buildings.In this paper,the ventilation and air conditioning energy consumption monitoring and management system has been studied in detail through theoretical analysis,frame design,data transmission and database design,software development and implementation methods.According to the related building energy consumption classification and measurement standards and basic principles,adopts a more detailed and accurate design of energy consumption classification for building ventilation and air conditioning systems,researched and developed an energy consumption monitoring and management platform for building ventilation and air conditioning systems only.This system adopts a communication method in which the controller that is responsible for collecting energy consumption data and the data server of the energy consumption monitoring management system use a communication thread pool and an EPOLL;the server and the energy consumption monitoring management platform(client application)Intercommunication between the thread pool and IOCP is used.The database of this system,the main function is to store various energy consumption data,user information(registered user name password,grouping,grade,etc.),configuration information(management rights configuration,template configuration,etc.).The system energy consumption monitoring and management platform adopts a domain model-driven approach,sets up a database table mapping,and carries out a partitioned database design method.This method can greatly reduce the capacity of the database and significantly improve the query efficiency of energy consumption data in the library.According to the framework design and demand analysis of the energy consumption monitoring and management platform(client application,monitoring end),Qt is selected as the development software and the MySQL database is used to implement the ventilation and air conditioning system energy monitoring and management platform(client application,monitoring end).Design and Development.The interface of the energy consumption monitoring and management software platform for ventilation and air conditioning systems is divided into seven parts: equipment information,energy consumption analysis,energy consumption statistics,cooling capacity analysis,energy efficiency analysis,energy efficiency diagnosis and data export.The device information interface provides a complete display of the operating status and energy consumption information of each device in the ventilation and air conditioning system.Energy analysis,energy consumption statistics,cooling capacity analysis,energy efficiency analysis and data export provide the necessary management and analysis statistics for the energy consumption data of all equipment and subsystems of the ventilation and air conditioning system.The energy efficiency diagnosis interface provides functions for making decisions and diagnosing the energy efficiency of each device and system of the ventilation and air conditioning system in a device-by-device and system-by-system manner.
