With the socio-economic level of development, smart-home this new term has been accepted by more and more people, intelligent control technology in smart home electronic products widely applied not only to optimize people's lifestyles and living environment, and convenient for people to effectively schedule and various energy saving, Realized the appliance, lighting, curtain controls and burglar alarm, timing control and telephone remote control devices.
This paper mainly introduces the integrated control system implementation plan, based on AT89C51 singlechip Microcomputer application system design, and focus on analysis of the system hardware design, detail the core chip selection, links to external circuit, the connection between the chip and chip circuit, including the infrared transmitter and receiver circuits telecontrol, the keyboard circuit, relay control circuit, PC and MCU communications content. The systems operation is simple, may realize the short distance or the long-distance range television stop-go control, the channel selectivity control, air conditioning's stop-go control as well as the pattern transformation and the temperature control control.
