System and method for diagnosing air conditioner failure based on data fusion in internet-of-things environment

Abstract

The invention relates to a system and a method for diagnosing air conditioner failure based on data fusion in an internet-of-things environment. The failure diagnosis of air conditioning equipment is realized by analyzing and judging data in a database of the system for diagnosing the air conditioner failure and carrying out a corresponding decision. The system comprises a plurality of environment modules, a plurality of air conditioner wireless measurement and control modules, a plurality of room controllers and at least one management computer. The environment modules acquire environmental parameters of rooms; the air conditioner wireless measurement and control modules acquire state and parameter information of air conditioners; the room controllers communicate with the environment modules and the air conditioner wireless measurement and control modules through a wireless sensor network, and are connected with the management computer through an ethernet network; and the management computer performs unified management on data in a form of a database, extracts the environmental temperature, the humidity, the carbon dioxide concentration, air conditioning parameters and the like in the database, integrates the information to perform data processing, comparison and analysis, and judges the states and the tendencies of the air conditioners to diagnose the air conditioner failure.

Description

technical field [0001] The invention relates to an air conditioner fault diagnosis system and method based on data fusion under the Internet of Things environment. Background technique [0002] 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 research of building electrical equipment. The Internet of Things for building equipment is a complex network composed of various building electrical equipment through the Internet of Things technology. Building electrical equipment is interconnected into a unified network through different media (wired, wireless, etc.) and forms (fixed, mobile, etc.). Obtain information (receive commands, sense information, data, etc.) and serve the network (provide information, perform calculations, impl...
