Pulse-Encoded Signal Messaging Across Variable Pulse Intervals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in transmitting data concurrently with pulse-encoded signals, particularly in automotive applications, where the varying frequency of pulses can result in message truncation due to limited time between consecutive pulses.
Innovation Solution
A method is provided for transmitting a message concurrently with a pulse-encoded signal by assigning an identifier and transmitting portions of the payload between consecutive pulses, where the pulse-encoded signal encodes information by varying the frequency of pulses, allowing the message to be transmitted over multiple transmission periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is transmitted between consecutive pulses of a pulse-encoded signal, then data communication is enabled, but message truncation occurs due to limited time between pulses
Solution Approach 1:
The message is divided into multiple segments, with each segment transmitted in a separate transmission window between consecutive pulses. This segmentation allows the complete message to be transmitted over multiple pulse cycles without truncation, resolving the contradiction between transmission efficiency and message completeness.
2Measurement precision
If the pulse frequency is increased to improve measurement resolution, then the time between consecutive pulses decreases, but the available transmission time for data is reduced
Solution Approach 1:
Data transmission is performed periodically in transmission windows that are synchronized with the pulse-encoded signal cycles. This periodic action allows data to be transmitted at regular intervals without interfering with the pulse frequency, enabling both high measurement precision and adequate transmission time.
Solution Approach 2:
The transmission scheme utilizes the time dimension by extending message transmission across multiple pulse cycles rather than attempting to fit the entire message within a single interval. This dimensional approach to time management allows high-frequency pulses to coexist with complete message transmission.
3Speed
If the entire message is transmitted in a single transmission window, then transmission speed is improved, but message truncation occurs when time between pulses is insufficient
Solution Approach 1:
The message is segmented into multiple parts that are transmitted sequentially across different transmission windows. This segmentation prevents truncation while maintaining efficient transmission by utilizing every available time window between pulses, thus resolving the contradiction between transmission speed and message completeness.
