Power Line Communication Synchronization via AC Frequency

The patent implements periodic synchronization actions where collector devices transmit synchronization packets at regular intervals to endpoint devices. This periodic action maintains network time across all devices, ensuring that despite the large number of endpoint devices, synchronization is achieved through repeated, timed synchronization events rather than continuous complex coordination.

The patent introduces collector devices as intermediary components between the command center and endpoint devices. These collectors act as local time servers that receive time information from the command center and distribute it to multiple endpoint devices within their coverage area, thereby simplifying the synchronization architecture and reducing direct coordination complexity between the command center and thousands of endpoints.

The patent segments the large-scale communication network into multiple smaller zones, each managed by a collector device. This segmentation divides the thousands of endpoint devices into manageable groups, allowing for localized time synchronization and reduced signal interference within each zone. The segmentation approach enables independent coordination of each collector's endpoint devices, preventing interference from propagating across the entire network.

The patent employs periodic transmission of synchronization packets and time information at scheduled intervals rather than continuous transmission. This periodic action reduces the overall signal load on power distribution lines, minimizing the probability of signal interference and collision while still maintaining adequate data transmission capacity for managing large numbers of endpoint devices.

The patent implements self-service timing mechanisms where endpoint devices automatically adjust their local clocks based on time information received from collector devices. Each endpoint device independently performs timing synchronization without requiring complex centralized coordination for each device. This self-service approach maintains precise timing for reliable communication while reducing the overall system complexity by distributing the timing maintenance function to individual devices.

The patent incorporates feedback mechanisms where collector devices transmit time synchronization packets to endpoint devices, which then adjust their local timing based on received information. This feedback loop ensures that timing drift is continuously corrected, maintaining communication reliability. The feedback-based timing adjustment is simpler than complex predictive coordination schemes because it relies on actual measured timing deviations rather than attempting to preemptively coordinate all devices.
