Motor Encoder Data Transmission Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor control systems face challenges in sending information generated over multiple periods, leading to incomplete data transmission due to time constraints, which affects data reliability and efficiency.
Innovation Solution
The motor control system incorporates a rotation position sensor, a first addition information generator, and an identification information generator to send data including rotation position, first addition information, and identification information, allowing for efficient data transmission even when first addition information generation takes longer than the sending period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is sent only within one sending period, then data transmission speed is maintained, but information generated over multiple periods cannot be completely transmitted
Solution Approach 1:
The patent segments data into two types: data that can be generated within one sending period and data that requires multiple periods. This segmentation allows the system to transmit different data types through appropriate channels - time-critical data within each period and complex multi-period data through accumulated transmission, resolving the contradiction between transmission speed and data completeness.
Solution Approach 2:
The system performs preliminary classification of data based on generation time requirements before transmission. By identifying which data can be generated within the sending period and which requires accumulation over multiple periods, the system prepares transmission strategies in advance, ensuring both timely transmission of critical data and complete transmission of complex data.
2Reliability
If all data is transmitted every sending period, then data availability is improved, but transmission efficiency decreases
Solution Approach 1:
The patent applies different transmission qualities to different data types. Critical data that must be available every period is transmitted with high frequency, while less time-critical data that can be generated over multiple periods is transmitted with lower frequency. This local differentiation of transmission quality maintains data availability where needed while improving overall transmission efficiency.

AI summary
An encoder includes a rotation position sensor, a first addition information generator, an identification information generator, and a sender. The rotation position detector is configured to detect a rotation position within one rotation of a rotation shaft of a motor. The first addition information generator is configured to generate first addition information for a period at least longer than a data sending period. The identification information generator is configured to generate identification information by which at least the first addition information is identifiable as information to be sent. The sender is configured to send, for the data sending period, sending data including the rotation position within one rotation. The sending data includes first sending data including the rotation position within one rotation, the identification information, and the first addition information.
