Dali Master Controller Unit with a Wireless Connection and Application Software

In this study DALI controller device with a wireless connection will be constructed. The device will be used as a platform for studying software solutions to implementing embedded DALI system, the feasibility of DALI, the electrical performance of DALI interface and the wireless connection. The major tasks of this study are developing the embedded software for DALI controller, for the wireless module and the application software for a PC. The hardware for the platform requests various types of technologies. Evaluation boards and modules will be utilized as far they are available. However, at least DALI interface circuitry and DALI power unit must be entirely self-made. The platform and the software will be tested with several light ballasts. The wireless link will be tested in indoor environment. RF propagation tests will show what power levels will be required and how sensitive the RF-link is for the mutual orientation of the antennas. The device is named as a master controller unit because it serves as the main controller and commissioning tool, allowing the user to enter short addresses for the light ballasts, defining groups and scenes and executing other configuration tasks.
