Abstract
With the development of socio-economic, people pay more and more attention to the smart residential. As the core device of electric control system, central controller develops quickly. What’s more, the updates of hardware circuit and software design about central controller are changing every day as well. This work introduces the system design of central controller in detail, including design of hardware and software.
In regard to the principle of single-chip control, this paper introduces the functions of pins, crystal oscillator circuit and Reset circuit of AT89C52 in detail. And it is also about connectivity problems between single-chip and other devices.When refers to Infrared remote control on the adoption of electrical equipment, it explains the realization of signals transmission and inception, system design of infrared transmission and inception, and infrared control with central controller on Infrared Technology. In addition, it is related to the main components of the Interface Technology of central controller: optocoupler, relay and drive circuit, Serial communication interface circuit RS232. Single-chip realizes the communication with PC by RS232.
Keywords: Central Control System; SCM; Infrared Remote Control
