【正文】 microputer, and the auxiliary ones are based on AT89C2051. The system can do many jobs, such as wired munication, wireless data transmitting, controlling and display. The paper describes the designing process of the circuit at length, including: keyboard and LED display circuit, RS485 munication circuit, wireless transmitting circuit, control circuit of lighting, watchdog circuit, etc. The designing of software mainly includes the several programming, such as wired munication, wireless data transmitting, lamplight controlling, timed controlling, keyboard scanning and LED displaying. The wired munication programming function is that through Masterslave munication method based on RS485 the host controller sends orders to the all auxiliary controllers or each one, including: turning on lighting, turning off lighting, regulating brightness of lighting, controlling timed lighting, etc. The wireless data transmitting programming function is that by wireless transmitter it realizes wireless controlling of the lighting, and achieves the functions identical to wired munication. Key Words: Host controller, Auxiliary controller, Singlechip microputer, Wired munication, Wireless data transmitting, controlling brightness of lighting, Timed controlling 鄭州大學(xué) 物理工程學(xué)院 畢業(yè)論文 I 目 錄 摘 要 .......................................................................................................................
