Splitter for LED Display Systems Reducing Controller Count
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large LED display systems with numerous independent screen bodies, the requirement for multiple output network ports increases costs when using multiple system controllers to connect each screen body, as transversal wiring is not allowed between screen bodies.
Innovation Solution
A splitter device with a processor that forwards image data to multiple loading interfaces, allowing each display unit to determine its sequence number and control its LED display assembly, thereby reducing the need for multiple system controllers and output network ports by configuring multiple display units into independent screen bodies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple system controllers are used to connect each independent screen body, then each screen body can be independently controlled, but the cost increases greatly
Solution Approach 1:
Multiple system controllers are merged into a single system controller by introducing a splitter device. The splitter receives image data from one system controller and distributes it to multiple loading interfaces, each connected to independent screen bodies. This allows one system controller to control multiple screen bodies independently through the splitter's sequence number assignment and data distribution mechanisms.
Solution Approach 2:
A splitter device is introduced as an intermediary between the system controller and multiple screen bodies. The splitter acts as a mediator that receives image data from the system controller, assigns sequence numbers, and distributes the data to appropriate loading interfaces. This intermediary enables one system controller to effectively control multiple screen bodies without requiring multiple controllers.
2Quantity of substance
If the number of output network ports is increased to connect more screen bodies, then more screen bodies can be connected, but the cost increases
Solution Approach 1:
The output network ports are segmented and virtualized through the splitter device. Instead of requiring physical separate ports for each screen body, the splitter divides the single input stream into multiple output streams by assigning different sequence numbers to different loading interfaces. This segmentation allows one physical port to serve multiple logical connections.
Solution Approach 2:
A single output network port on the system controller is made universal by using the splitter to distribute its output to multiple loading interfaces. The splitter enables one port to perform the function of multiple ports by dynamically assigning sequence numbers and routing data to different screen bodies, thus providing multi-functionality to a single port.
3Device complexity
If a single system controller is used to control multiple independent screen bodies, then cost is reduced, but the problem of configuration and data distribution arises
Solution Approach 1:
The splitter performs preliminary actions by pre-assigning sequence numbers to each loading interface and establishing the data distribution path before actual image data transmission. This preliminary configuration enables the system controller to simply send image data without needing to manage complex individual connections to each screen body, thus reducing configuration difficulty.
Solution Approach 2:
The system implements feedback mechanisms where the splitter monitors the sequence numbers and routing status, and the assembly controllers report their status back through the loading interfaces. This feedback loop allows automatic detection and adjustment of configuration issues, reducing the complexity of manual configuration and troubleshooting.
