【正文】 ion, 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. Traditional building automatic controlling system only includes such subsystems: prehensive wires, puter work, safe defending, fire defending and closedcircuits TV monitoring systems and so on. But in the recent years, with the economic development and the progress of the science and technology, people have 設(shè)計(jì)巴巴工作室 put forward more higher demands for energyconservation of lighting lamps and scientific management, which makes the lighting control system of the classroom have such functions as energyconservation, convenience, intelligence, etc. What’s more, it can improve the efficiency of the work and study, result in many kinds of lighting effects, and improve the management level. There are the design philosophy of this system, operation principle of every chip, and such relevant problems as the choice, making and debugging of the ponents and unit circuits about lighting control system of classroom, which regards the microcontrol unit as the control core of the system. This control system is suitable for such occasions as various kinds of multimedia classrooms, station waiting rooms, offices, etc. It is mainly posed of lightening control unit, moving sensor unit, illuminative sensor unit, handedcontrol unit, and so on. The target of the design is intelligent lightening, scientific management, and energyconservation and cost conservation. The AT89C2051 with the feature of cheap cost has been used as the control unit in the whole design. The whole system not only has been introduced in the paper, but also has been successfully finished with series of the Dais microcontrol unit. The experiment suggests that this design can easily
