Abstract
In order to change the inconvenience of management and energy waste of traditional building lighting system, this paper designs an intelligent control system of building lighting based on bus technology. The system consists of the upper computer, the control subsystem of the host computer, the control subsystem of the relay and the control subsystem of the switch. Hierarchical control method is proposed, which can support the manual operation and automatic operation mode, each corresponding lighting load switch control, upper machine and the host can be modified to set the switching time of the load, and the host and the upper machine can match from the other sensor control signal to work together, when a control signal elimination is according to the predetermined plan on or off load power supply. The system has the advantages of high efficiency, convenience, low cost, good interactivity, fast response speed and high degree of automation.
