Power Line Communication Apparatus State Switching for Energy Savings

The patent implements dynamic power state adjustment by switching between working state and sleep state based on network activity detection. The system monitors network traffic and automatically transitions the power source between active conversion mode and standby mode, optimizing the balance between service availability and energy consumption rather than maintaining a fixed continuous operation state.

The system employs periodic detection of network states to determine when to transition between power states. By continuously or periodically monitoring network activity, the system can identify idle periods and initiate sleep mode, while also ensuring rapid wake-up when traffic appears, thus achieving energy savings without significantly compromising availability.

The patent dynamically adjusts the power source state based on real-time network conditions, transitioning from continuous AC conversion to periodic operation. This dynamic state change reduces cumulative heat generation while maintaining the ability to provide service when needed, thereby stabilizing the working temperature and improving overall system reliability.

The system converts the potential harm of continuous operation (excessive heat) into a benefit by using the detected network idle state as a trigger to reduce power consumption. The idle detection mechanism, which could potentially cause false wake-ups, is instead used to justify entering sleep mode, transforming a possible reliability issue into an energy-saving opportunity that also reduces thermal problems.

The patent implements self-service functionality where the PLC apparatus automatically monitors its own network state and decision-making process. The system independently detects idle conditions, evaluates whether to enter sleep mode, and executes the power state transition without requiring user intervention. This eliminates the need for manual power cycling while achieving energy savings, thereby reducing operational complexity.

The system employs feedback mechanisms where network activity information is continuously fed back to the control logic, which then adjusts the power source state accordingly. This closed-loop control ensures the system responds automatically to actual usage patterns, providing intelligent energy management without requiring user input or complex manual procedures.
