Abstract
With the development of Internet of Things (IoT) technology, smart home systems have gradually become an integral part of modern home automation. Power Line Communication (PLC), which utilizes existing power lines for data transmission, offers advantages such as no need for additional wiring and low cost, demonstrating broad application prospects in smart home systems. This study aims to construct an efficient and stable smart home system based on PLC to achieve intelligent control and management of home devices. By analyzing the communication principles of PLC and the requirements of smart homes, a hybrid networking solution integrating ZigBee short-range wireless communication technology is proposed, effectively addressing issues of signal attenuation and weak interference resistance in PLC. The smart home system, designed and implemented with functionalities including environmental monitoring, appliance control, and security alarm, adopts a modular design approach to enhance system scalability and maintainability. Experimental results indicate that the system operates stably and reliably, accurately executing commands across different scenarios with short response times and low bit error rates. Compared to traditional smart home systems, the PLC-based smart home system proposed in this study fully utilizes power line resources, reduces installation costs, and improves communication efficiency, providing new insights and technical support for the promotion of smart home systems. Its innovation lies in combining PLC with ZigBee technology, leveraging the advantage of PLC not requiring additional wiring while compensating for its inherent limitations through ZigBee, thus contributing unique value to the development of the smart home domain.
