A Design of Embedded DALI Controller

This paper solved the problem of how to connect DALI (digital addressable lighting interface) with Internet. A design of embedded DALI dimming controller which based on muC -Linux embedded operation system is presented, the hardware construction using ARM7 MCU and the software conversion between thin TCP/IP and DALI protocol are mainly expounded. The DALI receiving/transmitting circuits and the information frame are also introduced. The signals demonstrate that the DALI controller is designed according to the specification of DALI and improved in some aspects. This controller can be applied in an intelligent remote illumination control system, with the advantage of energy conserving and Internet visiting.
