Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing failure information transmission systems for motor control apparatuses face challenges in efficiently transmitting multiple failure signals simultaneously, leading to potential delays and increased damage to circuits due to complex configurations.
Innovation Solution
A failure information transmission apparatus that transmits multiple failure signals as distinct pulse signals, prioritizing higher-priority information by varying parameters such as frequency, number of pulses, or pulse width, allowing for rapid and reliable transmission through a single transmission path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple failure signals are transmitted sequentially through one transmission path, then the configuration is simple, but transmission may be delayed when multiple failures occur simultaneously
Solution Approach 1:
The patent uses periodic pulse signals with different characteristics (width, frequency, or number of pulses) to transmit multiple failure information types simultaneously through a single transmission path. Each failure type is represented by a specific pulse pattern, allowing the receiver to identify multiple failures at once without sequential transmission delays.
Solution Approach 2:
The patent varies pulse signal parameters (width, frequency, or number of pulses) to encode different failure information. By changing these parameters, the system can transmit multiple distinct failure signals through the same transmission path without requiring multiple separate paths, thus maintaining simplicity while eliminating transmission delays.
2Loss of time
If multiple failure signals are transmitted simultaneously through separate paths, then transmission delay is reduced, but the equipment configuration becomes complicated
Solution Approach 1:
The patent merges multiple failure signal transmission functions into a single transmission path by using differentiated pulse characteristics. Instead of requiring separate physical paths for each failure signal, the system combines them into one path while maintaining distinguishability through pulse width, frequency, or pulse count variations.
Solution Approach 2:
The single transmission path is designed to handle multiple failure information types simultaneously by encoding them with different pulse characteristics. This multi-functional approach allows one transmission path to replace what would traditionally require multiple dedicated paths, reducing overall system complexity.
3Reliability
If failure information is transmitted as standardized signals, then transmission reliability is high, but the ability to prioritize different failure types is limited
Solution Approach 1:
The patent uses variable pulse parameters (width, frequency, or number of pulses) to encode both the type and priority of failure information. This approach maintains the reliability of standardized signal transmission while adding the versatility to prioritize different failure types, as the receiver can identify both the failure type and its transmission priority from the pulse characteristics.
Data Source
AI summary
A failure information transmission apparatus includes a transmission circuit and a reception circuit. The transmission circuit transmits a plurality of pieces of failure information related to a plurality of failures as pulse signals different from one another via the same transmission path. The reception circuit receives the pulse signals transmitted by the transmission circuit via the same transmission path and identifies the failure information based on the pulse signal received. If the plurality of failures occurs at the same time, the transmission circuit transmits preferentially transmits failure information with higher priority of transmission.
