Abstract.With the development of society, people have higher and higherrequirements for the convenience of life. Therefore, it is of great practical significanceto study the remote control system of household appliances based on single chipmicrocomputer. This paper first introduces the common scheme of remote controltechnology of home appliances, then analyses the module of remote control system ofhome appliances based on single chip microcomputer, and finally gives the designscheme of remote control system of home appliances based on single chipmicrocomputer.Keywords: Remote Control System, SCM, Household Appliances1. IntroductionWith the rapid development of remote control technology, the traditional home appliance controlsystem has been unable to meet people's requirements for the convenience of life, so the requirementsfor the home appliance remote control system are increasingly high. The design of the remote controlsystem of home appliances based on single-chip microcomputer can be designed reasonably based onthe actual needs of people for home equipment, give play to the advantages of remote controltechnology of single-chip microcomputer, so as to further improve the convenience of people's life[1].With the development of information technology, Internet information technology is more and moreused in the remote control of smart home appliances, which has become the development trend ofsmart home appliances. Therefore, it is of great practical significance to study the remote control ofMCU based on mobile Internet.2. Common scheme of remote control technology for home appliancesAt present, the more common remote control system of household appliances mainly has three ways asshown in Figure 1. Among them, infrared remote control is to send the corresponding informationthrough a specific encoding by the transmitter, while the receiver analyses the received informationthrough a specific decoding strategy, and finally completes the identification and control of theencoded information
