Wireless Spliced Screen Synchronization via Intermittent Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current spliced screen display systems rely on wired signal transmission, limiting flexibility and scalability, especially in large-scale applications where simultaneous and synchronized display across multiple screens is challenging.
Innovation Solution
A wireless communication-based method using a LoRa base station to send control information intermittently to control multiple display screens, including first information to turn off receiving components and second information to display after a preset time, ensuring synchronized display across the spliced screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired signal transmission is used for spliced screen display, then signal transmission stability is improved, but installation flexibility and scalability are limited
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. Each display screen is equipped with a wireless communication module that receives control signals wirelessly, eliminating the need for physical signal cables. This substitution maintains reliable signal transmission while dramatically improving installation flexibility, allowing screens to be positioned anywhere within wireless range and enabling easy system expansion.
2Reliability
If control information is sent continuously to all display screens, then display synchronization is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous transmission, the patent implements periodic control signal transmission. The control device sends display control information at specific time intervals rather than continuously. Each display screen enters a low-power state between receptions and only wakes to receive new control signals when needed. This periodic approach maintains display synchronization while dramatically reducing overall energy consumption of the system.
Solution Approach 2:
Each display screen autonomously manages its own power state based on received control signals. When a screen receives control information, it activates its receiving component and processes the signal independently. After processing, it can enter a low-power state without requiring continuous power from the control device. This self-service mechanism allows each screen to optimize its own energy consumption while maintaining system-wide synchronization.
3Speed
If receiving components remain active continuously, then signal reception responsiveness is improved, but power consumption increases
Solution Approach 1:
The patent makes the receiving component's operational state dynamic rather than static. The receiving component dynamically switches between active and low-power states based on system needs. When control signals are being transmitted, receiving components are active to ensure responsive signal capture. When no signals are pending, they transition to low-power states. This dynamic adaptation maintains responsiveness during operation while minimizing energy consumption during idle periods.
