Multi-Fan System Single-Input Terminal Signal Decoding

The patent applies universality by designing a single input terminal that can control multiple fans and light emitting elements through a multi-fan system. The control source circuit generates driving signals that are distributed to multiple electronic devices, each with a single input terminal, enabling one terminal to perform multiple control functions instead of requiring separate terminals for each device

The patent segments the control system into a control source circuit and multiple electronic devices, where the control source circuit divides driving signals into multiple signal strings with different identification codes. Each electronic device receives the segmented signal string through its single input terminal and processes only the relevant signals, allowing one terminal to effectively control multiple components

The control source circuit segments its output into multiple driving signal strings, each containing identification codes that correspond to different electronic devices. This segmentation allows the control source circuit to maintain a single output terminal while still providing differentiated control signals to multiple devices through signal string division and identification code assignment

The patent introduces identification codes as an intermediary mechanism between the control source circuit and multiple electronic devices. These identification codes act as mediators that enable a single output terminal to communicate with and control multiple devices without requiring multiple physical output terminals, thus reducing device complexity while maintaining control coverage
