Fan Chip Signal Transmission Delay Detection System

The patent applies preliminary action by measuring the signal transmission delay in advance through a detection process before the fan control operation begins. The delay time is measured by sending a detection pulse signal and recording the time difference between transmission and reception. This pre-measured delay value is then stored and compensated for during actual fan control operations, ensuring accurate timing control despite the inherent transmission delay caused by circuit wiring and components.

The patent implements self-service by enabling the fan chip to autonomously perform the delay detection and compensation functions. The fan chip includes a detection unit that generates detection pulse signals, measures the transmission delay, and stores the delay value in its own storage unit. During control operations, the fan chip automatically retrieves and applies the stored delay value for compensation. This self-contained approach eliminates the need for external detection equipment or complex processing mechanisms, maintaining system simplicity while ensuring control accuracy.

The patent applies merging by integrating the delay detection and compensation functions directly into the fan chip's existing control structure. The detection unit, storage unit, and compensation mechanism are combined within the fan chip itself, merging multiple functions (pulse generation, delay measurement, value storage, and compensation application) into a single integrated component. This eliminates the need for separate detection equipment and reduces overall system complexity while achieving precise fan operation at predetermined times.
