Warning Light Control Method Using ID-Based Synchronous Flashing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional warning light systems require additional electronic control devices to coordinate the flashing of multiple lights, leading to poor coordination, increased manufacturing costs, and reduced price competitiveness in the market.
Innovation Solution
A warning light control method that assigns an ID Number to each light, allowing the Starter to transmit data, clock, and identity signals through the Data Bus to control multiple Receivers without the need for an additional electronic control device, enabling synchronous or asynchronous flashing in various modes (Synchronous, Interlace, Polling, and Recursive) and reducing manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an additional electronic control device is used to control multiple warning lights, then the coordination of flashing can be achieved, but the manufacturing cost increases and the warning effect coordination is still poor
Solution Approach 1:
The patent extracts the control function from a separate electronic control device and integrates it into the warning lights themselves. Each warning light is equipped with a control circuit that can independently receive control signals and generate flashing patterns, eliminating the need for a centralized electronic control device while achieving coordinated flashing through direct control signal transmission between lights.
Solution Approach 2:
Each warning light serves itself by having embedded control circuits that can independently process control signals and generate appropriate flashing patterns. The system achieves self-organization where each light unit can autonomously respond to control signals and coordinate with other lights without requiring external intelligent control, reducing overall system complexity.
2Reliability
If an additional electronic control device is used to control multiple warning lights, then the flashing coordination can be controlled, but the manufacturing cost and sales price increase
Solution Approach 1:
The control functionality is extracted from a separate expensive electronic control device and integrated directly into each warning light unit at the circuit level. This integration eliminates the need for additional control hardware, reducing component count and manufacturing cost while maintaining flashing coordination capability through direct control signal transmission.
Solution Approach 2:
The control circuit is merged with the warning light assembly, combining the lighting function and control function into a single integrated unit. This merging eliminates the need for separate control devices and reduces the overall system component count, thereby reducing manufacturing costs while maintaining coordinated flashing performance.
3Adaptability or versatility
If conventional electronic control devices are used, then multiple warning lights can be controlled, but the flashing effect coordination is poor and the warning effect is insufficient
Solution Approach 1:
The patent implements multiple dynamic flashing modes (synchronous, asynchronous, alternating,追逐) that can be dynamically selected and switched. Each mode provides different coordination patterns for multiple warning lights, enhancing the visual warning effect and adaptability to different operational scenarios while maintaining reliable coordinated control through direct signal transmission between light units.

AI summary
A warning light control method includes the steps of: accepting multiple warning lights to receive a start command to set up Flash Mode and numbering each warning light sequentially starting from 1, and using Flash Mode number to synchronously set ID Number of each warning light; setting the ID Number of a predetermined warning light as Starter and the remaining ID Numbers as Receivers; the warning light of Starter receiving Start Command from Control Bus through cable, and sending Data, Clock Pulse and ID Information from Data Bus, and selecting one for flashing by Flash Mode; warning lights of Receivers get Data, Clock Pulse and ID Information from Data Bus through cables thereof, and warning lights of Receivers and Starter are flashing synchronously or asynchronously; whether Control Bus of Starter and Receivers has received Change ID Command.
