摘要

According to the specifications of tunnel ventilation and lighting, in order to solve the problem of output control about high-power LED lighting, a kind of master-slave dynamic dimming control system is realized based on the DALI bus and low-power MCU with high performance. This system mainly consists of two units, one is the master device, and the other is the slave device. Master device generates the control strategy, and the slave device controls the current driver circuits after receiving the control signals. Thus the flexible dimming output of the end node LED modules can be achieved. Also the system supports remote data query and device management via Ethernet.
