Research on Power Line Carrier Communication Based on HVDC

Abstract

This paper mainly studies the control of LED lamps under the condition of centralized DC power supply by power carrier mode, and modifies the mature power carrier scheme in AC system to adapt to the DC system environment and realize reliable communication in DC system. Through the analysis of system functional requirements and the comparison of existing communication technologies, the overall architecture of DC tunnel lighting system is proposed. The system adopts two-tier structure, including monitoring center, communication controller and HVDC tunnel lighting control terminal. This system realizes the master-slave monitoring of the communication controller to the control terminal of HVDC tunnel lamps, and puts forward the modification scheme to the conventional power carrier scheme, and verifies the improved power carrier scheme of DC system through the Qijiashan tunnel lighting project.

Design of Healthcare Lighting in Medical Centers Based on Power Carrier Communication

“…The effective use of medical lighting control systems not only plays a positive role in the health of medical staff but also helps to achieve the effect of diagnosis and treatment, patient rehabilitation, and the improvement of doctor-patient relationships. At the same time, it is also conducive to hospital operation management and cost control (Chen et al, 2021). The medical lighting control systemmedical lighting control system design should meet the functional requirements and use purposes.…”
