During the transmission process, the signal can be amplified by adding relays, up to eight relays can be added, that is to say, the maximum transmission distance of RS485 can reach 10.8 kilometers in theory.
On the basis of not changing the design of the original lighting and power distribution control system, through the upgrade of the lighting intelligent management platform and street lamp intelligent control hardware, unified and refined management of lighting is implemented to achieve remote monitoring of lighting, intelligent management and control, energy saving and consumption reduction The “Trinity” effect of the “Trinity” realizes the organic unity of safety lighting, green lighting, smart lighting and efficient lighting.
