Design of Automatic Lighting System for Underground Space of Subway Hub Station Based on DALI Protocol
In view of the large difference between the illuminance adjustment value and the contract value of the current under-ground space automatic lighting system of subway hub station and the time-consuming lighting adjustment,an underground space automatic lighting system of subway hub station based on DALI protocol is proposed.STM32F103RCT6 is selected as the core processing chip of the controller,and the new central controller development board is set.The DC worm-gear reducer is selected as the system driving equipment,and the wireless communication module is optimized to adapt to the form of the up-per computer to complete the optimization of the system hardware framework.The lighting model of underground space is con-structed and used to calculate the required illumination and lighting uniformity.The lighting regulation scheme of DALI proto-col is set to complete the lighting adjustment of subway underground space.Test results show that the system can reduce the difference between the illumination adjustment value and the contract value under different test environments,improve the lighting adjustment accuracy and shorten the lighting adjustment time.
