Remote access of digital addressable lighting interface (DALI)

The Digital Addressable Lighting Interface (DALI) standard developed by the lighting industries is emerging as the preferred lighting control method over the existing systems because of its increased energy savings and ergonomics through digital lighting control. In this thesis, a design methodology to enable the emerging DALI implemented lighting system to be controlled by a user from remote locations has been carried out.; The DALI system is established as remotely accessible only if the remote user is able to communicate with all the dimming ballasts individually. To accomplish this, an addressing technique to uniquely identify all the DALI units is designed.; The remote user must be able to control the dimming ballast efficiently and is accomplished by designing Remote Interactive Interface software with the aid of Visual Basic 6. The operational routine for the controllers implemented in the DALI System are programmed with C programming language.
