Power Controller Signal Pattern Check for Manual Rescue Mode

The patent applies periodic action by using pulsed instruction signals with specific patterns instead of continuous signals. The controller sends periodic pulses with defined characteristics (duration, interval, pattern) that must match predetermined patterns to be recognized as valid commands. This temporal structuring allows the system to distinguish between intentional periodic control signals and random unintentional interference from short circuits, thereby maintaining reliability while reducing susceptibility to harmful factors.

The patent applies self-service by enabling the controller to automatically compare received signal patterns against stored predetermined patterns and independently determine whether signals are intentional or unintentional. The system performs self-validation through pattern matching algorithms, eliminating the need for external verification mechanisms. This automated self-service approach enhances safety through continuous validation while avoiding the complexity of additional external monitoring devices or manual verification procedures.
