1Ease of operation
If full deplux communication method is used to enable bidirectional communication, then communication convenience is improved, but wiring costs and circuit costs increase due to requiring additional wires
Solution Approach 1:
The patent introduces a communication module as an intermediary device that converts wireless signals to wired signals, enabling bidirectional communication without requiring additional wires in the control loop. The communication module acts as a mediator between the wireless control device and the wired light devices, translating communication protocols and facilitating data exchange through existing wiring infrastructure.
Solution Approach 2:
The patent replaces the mechanical wiring system with a wireless communication system for the control interface. By using wireless communication protocols (such as WiFi, Bluetooth, or Zigbee) between the control device and communication module, the system eliminates the need for additional bidirectional wiring while maintaining full deplux communication capabilities.
2Device complexity
If simplex communication method is used to simplify wiring, then wiring complexity is reduced, but communication functionality deteriorates as only unidirectional transmission is allowed
Solution Approach 1:
The patent implements dynamic role assignment where devices can switch between master and slave roles based on communication direction. The communication module enables the system to dynamically transition between unidirectional and bidirectional communication modes, allowing light devices to send feedback signals to the main controller when needed while maintaining simple wiring architecture.
Solution Approach 2:
The patent incorporates feedback mechanisms where light devices can send status information and feedback signals back to the main controller through the communication module. This enables closed-loop control functionality while maintaining the simple wiring structure characteristic of simplex communication systems.
