Inrelligent Lighting System Based Ontesting Human Body Feature

The book introduces the development of intelligent lighting system in a systematicway and sets forth the meaning of the application of intelligent lighting, analyzingseveral typical intelligent lighting systems now available (such as EIB technologyAustralia Dynalite electronic lighting control system) and already—built engineeringcases. In view of the weaknesses of existing systems: low intelligent level, poorcompatibility, and low automation, the book raises a design for a real intelligent andautomatic lighting system based on testing the position of human body.Besides all functions that a intelligent lighting system possesses, the system canalso bring about "accompany—styled" lighting through testing the position of body;It can change lighting model automatically according to environment, the number ofpeople; It can adjust to Bus Agreement in different places and make controlcommonly—used by designing controls and bus adaptors separately.The system adopts two—level net structure. Main net uses TCP/IP Agreement,subnet uses CSMA/CD Agreement; control adopts the design based on ATC89C52single chip; light control circuit uses a design based on light adjustable ballast controlchip KA7543; the test of body position adopts various means includingelectric—released and electrical sensor technology, radio frequency technology,pressure sensor technology, picture processing technology. Meanwhile, It has thefunctions of testing light strength, lowering and raising curtains and opening andclosing louvers.
