Research And Development Of Intelligent Air Conditioning Based On Mobile Internet

The mobile internet refers to a kind of network that as its access networks in MobileCommunication Network to provide voice, data, multimedia and other service.Cell phones,tablets and other mobile terminals serve as a forum where the network service can be realized.GSM Mobile Communication Network is an important part in the transmission of MobileInternet. It has excellences of wide usage, high quality of communication and good stability.SMS that GSM provides to transmits control instructions and data is convenient and efficient,is of high usage rate with great anti-interference performance and without area limitation.Household appliances industry is the most suitable industry for network’s development. Withthe rapid development of mobile internet technology, people’s demand for householdappliances products’ performance is getting higher and higher, Intelligence of air-conditionerand other appliances have become an inevitable trend of industry’s development.This thesis researches and develops a remote control system of intelligent air-conditionerthat is based on Mobile Internet,users can use regular phone or smart phone with controlsoftware to realize the remote control of the air-conditioner.Before using the system, usersneed to bond the phone to the intelligent air-conditioner. In this system, users can bond onephone to different air-conditioners and can also bond one air-conditioner to different phonesas needed. When the bonding process accomplished, users can remotely set up operationparameter and inquire operation condition through phones; regular phone or control softwareof smart phones will send a specific form of massage commands to the bondingcommunication module through SMS after receieving users’ remote control commands; thencommunication module will discode the communication data and send control information toair-conditioner intelligent controller through485or TTL after receieving SMScommands;air-conditioner intelligent controller executed commands after receiving controlinformation commands and meanwhile executed results will be fed back to smart phonethrough SMS. When air-conditioner malfunctions, intelligent controller will automaticallysend messages to bonding phones through communication module, which realizes thefunction of auto alarm.This thesis mainly researches on both software and hardware design of the GSMcommunication module of which PIC18F26K22microcontroller and GSM module withworking frequency of900MHz/1800MHz are the core components.Test result shows that thesystem realized the function of remote control, inquiry of operation condition and auto alarmof intelligent air-conditioner. And this system operates stably, manipulated simple, costs little, and has high value of utility.
