Description

technical field [0001] The invention relates to a power line carrier and wireless bluetooth dual-channel automatic switching system and method, belonging to the fields of bluetooth communication and carrier communication. Background technique [0002] At present, household controllers (such as remote controllers) use infrared induction to realize control operations on household appliances. However, infrared signals are easily interfered by various heat sources, light sources, radio frequency radiation and thermal airflow. Therefore, the smart home experience for users today is not ideal. The present invention provides a power line carrier and wireless bluetooth dual-channel automatic switching system and method, adopts parallel channels, so that the two channels can work independently, and can also automatically switch to cooperate with each other. The invention effectively ensures the high efficiency and reliability of information transmission, and provides a strong guara...
