The invention discloses a digital addressable
lighting control system and a method thereof. The
system consists of master nodes and slave nodes numbered from 1 to 64 which are hung and connected on a DALI
bus, all the sensors and a PC on which DALI
application software runs are connected with the main nodes, and the slave nodes comprise two parts of DALI
interface circuits and electronic dimming ballasts and serve as a
system actuator for driving fluorescent lamps. The
actuator controls the fluorescent lamps according to commands of the main nodes and the preset working parameters, the slave nodes are taken as the
system actuator, a
control unit thereof reads the real-time working states of the fluorescent lamps and an output module and feeds back to the main nodes by the DALI
bus, then the digital addressable
lighting control system can not only feed back the real-time state of the
control unit of the actuator, but also feed back the real-time states of an executive unit and controlled objects, and maintenance personnel and a user can grasp the full picture and the details of the system. The digital addressable
lighting control system adopts the electronic ballasts with separated easily damaged parts and non-easily damaged parts, and only the easily damaged parts need to be replaced during the life cycle of the actuator, thereby effectively reducing the overall owning cost of the user.
