Event-Driven Pulse Pair Transmission for Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing event-based transmission systems suffer from significant overhead and collision risks due to the use of headers containing identification data, leading to inefficient communication.
Innovation Solution
The proposed event-driven transmission method converts events into corresponding pulse pairs, where a delay between pulse pairs serves as an identifier, reducing overhead and collision risk, and employs encoding techniques such as Manchester code and differential phase modulation for efficient transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If headers containing identification data are used for message packets, then receiver recognition and clock synchronization are enabled, but transmission overhead increases significantly
Solution Approach 1:
The patent extracts the identification function from the traditional message header and implements it through timing information. Each sensor's unique identifier is encoded in the temporal pattern of pulse pairs, eliminating the need for separate header fields containing identification data, thus reducing transmission overhead while maintaining reliable receiver recognition
Solution Approach 2:
The patent transitions from spatial/header-based identification to temporal-based identification. Instead of using identification data in the message header (spatial dimension), the system encodes identifiers in the time delays between pulse pairs (temporal dimension), achieving efficient transmission without sacrificing recognition capability
2Loss of information
If traditional message packet transmission is used, then complete data communication is achieved, but collision risk increases
Solution Approach 1:
The patent employs periodic pulse pair transmission with specific timing patterns. Each sensor transmits pulse pairs at predetermined time intervals based on its identifier, creating a time-division multiplexed communication system that inherently reduces collision probability while maintaining complete data communication through systematic periodic transmission
Solution Approach 2:
The system performs preliminary timing synchronization and identifier encoding before actual data transmission. By pre-establishing the temporal pattern for pulse pairs based on sensor identifiers, the system prevents collisions before they occur, ensuring reliable communication without requiring complex collision avoidance protocols
3Loss of energy
If pulse pair transmission with delay encoding is used, then overhead is reduced significantly, but transmission complexity increases
Solution Approach 1:
The transmission system encodes identification information automatically through the inherent timing characteristics of pulse pair generation. Each sensor's identifier is self-encoded in the time delay between its pulse pairs, eliminating the need for separate encoding circuits or complex modulation schemes, thus reducing overhead without proportionally increasing device complexity

AI summary
An event-driven transmission method comprises converting at least one event to at least one corresponding pulse pair and transmitting the at least one pulse pair. In this context, a delay between each pulse pair represents a corresponding identifier with respect to the respective event or with respect to at least one corresponding object causing or experiencing the respective event.
