Intelligent Lighting Control System Using Illumination Sensor for Office Building

摘要

An intelligent lighting control system based on illumination information and time management is proposed for office building. A digital illuminance sensor is used to obtain the illumination of workspace plane and transmit it to the central controller. Real time clock, an independent timer of MCU, realizes the function that we can use different control strategies during different periods. The system use a PID controller to process the feedback illuminance information such that target illumination of workspace plane can be maintained. The proposed system design allows the users to acquire the system output and current illumination and can change the system output according to their own habits, making it suitable for practical indoor lighting applications.
