| Abstract | Street lamp is the natural node of smart city, and smart lighting system becomes the key of smart city. The stability of transmission and communication have become the key technologies of smart lighting system According to the classification of street lamp signals, for one-way control signals, the communication between the centralized controller and the single-lamp controller can be realized by coding the conduction angle of the thyristor in power supply. The communication principle by the conduction angle is analyzed, which is highly reliable and requires no additional communication lines and no high-frequency carrier. It is suitable for one-way and small data communication, which is the key guarantee for street lamp control. Then, based on the conduction angle communication, the design scheme of smart city lighting system is given, mainly including intelligent cloud platform, centralized controller, driving power and single lamp controller. |
