Central air-conditioning energy-saving system and method based on ontology

Abstract

The invention relates to a central air conditioner energy saving system and method based on a body. By means of the central air conditioner energy saving system and method, the defects happening when energy is saved through comprehensive information can be overcome. The method includes the steps of firstly, collecting environment information, device state information, device energy consumption information and the like through the central air conditioner energy saving system and storing the information into a database of the system; secondly, mapping the information in the database to the central air conditioner body, and conducting parsing, reasoning and analyzing on a body model on the basis that an energy saving rule is made; thirdly, judging the running state of an air conditioner so as to turn on or turn off devices of the central air conditioner energy saving system; finally, saving energy. The central air conditioner energy saving system comprises a plurality of space units in a building, wherein the space units are provided with central air conditioner terminals, and an environment detection module is arranged in each space unit. Meanwhile, a central air conditioner unit installation space is further arranged in the building, and an air conditioner device measurement and control module, a device energy consumption measurement module, a DDC and a monitoring center management computer besides the environment detection modules are arranged in the air conditioner unit installation space.

Description

Technical field: [0001] The invention relates to a body-based central air-conditioning energy-saving system and method, which belong to the field of combining automatic control, energy-saving technology and computer application. Background technique: [0002] my country is in a period of rapid economic development, and the process of urbanization is gradually accelerating. In order to meet people's work and living needs, a large number of new buildings need to be built. How to achieve sustainable development of buildings and create an energy-saving and comfortable environment for people is the construction industry. Important problems that people need to solve urgently. [0003] With the development of intelligent building technology, automation systems such as central air-conditioning computer control, constant pressure water supply, and intelligent lighting provide a comfortable working and living environment for buildings, and also provide effective means for the control r...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the knowledge and experience of system operation cannot be effectively applied to the energy saving of the system, and propose a central air-conditioning energy saving system and method based on the ontology. The system collects environmental information, equipment status information, equipment energy The energy consumption information is stored in the system database. On the basis of summarizing and analyzing the central air-conditioning system, a central air-conditioning ontology with equipment, environment, state, state value, energy consumption, etc. as the top concept is proposed. By mapping the information in the database to The ontology model forms a dynamic model that changes in real time with the system operation data, uses the knowledge and experience of system operation to formulate energy-saving rules, analyzes, reasoning and analyzes the ontology model according to the rules, obtains energy-saving optimization strategies, and judges the operation of air conditioners state, in order to start and stop the equipment of the air conditioning system, and finally achieve the purpose of energy saving
