    • Abstract
  • Traditional wireless communication will inevitably interfere with signals in electromagnetic sensitive scenarios. In order not to affect the stability and reliability of communication systems, combined with insensitive characteristic of visible light to electromagnetic field, a smart and lighting system with visible light as information carrier was built in electromagnetic sensitive environment. Firstly, 3-D space of 0.5m×0.5m×0.3m was used as room model and reasonable layout optimization method of indoor light source was carried out to make it meet the international indoor lighting standards. Secondly, the upstream and downlink of system and the signal frame structure were designed. The stable information transmission was realized. Finally, the physical model of the system was built and the system was debugged. The results show that the system can stably realize real-time monitoring and data transmission of lighting and indoor environment parameters. Bit error rate is less than 10-6. It can stably communicate for more than 10h. This study provides a reference for the layout parameters of large scenes.
