Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If operation information is converted into an image of a QR code and transmitted only at the timing when diagnosis is requested, then transmission complexity is reduced, but the amount of information for diagnosis is reduced and accurate diagnosis becomes difficult
Solution Approach 1:
The system performs preliminary action by continuously storing operation data in the ring buffer memory device before diagnosis is requested. This ensures that when a transmission command is received, sufficient historical operation data is already available for accurate remote diagnosis, eliminating the need to convert data to QR codes at the moment of diagnosis request.
Solution Approach 2:
The system creates a copy of operation data by storing it in both the ring buffer memory device and non-volatile memory device simultaneously. This copying mechanism ensures that data is preserved in multiple formats and locations, allowing transmission of comprehensive operation data without requiring complex real-time conversion processes.
2Measurement precision
If continuous temporal change data at a level where change tendency can be analyzed is transmitted, then diagnosis accuracy is improved, but data transmission volume and complexity increase
Solution Approach 1:
The system extracts only the necessary operation data from the continuous temporal change stream by using the ring buffer to store data at appropriate sampling intervals. When transmission is requested, only the relevant extracted data within the buffer is transmitted, maintaining diagnosis accuracy while avoiding transmission of excessive redundant data.
Solution Approach 2:
The system changes the parameter of data representation by storing operation data in a structured format in the ring buffer that preserves temporal relationships. This allows the transmission of continuous temporal change data in an efficient format that maintains the ability to analyze change tendencies without requiring complex real-time data processing.
3Loss of information
If operation data is continuously stored in memory, then data availability for diagnosis is improved, but memory resource consumption increases
Solution Approach 1:
The system segments memory resources by dividing them into two distinct parts: a ring buffer memory device for continuously storing operation data with temporal relationships, and a non-volatile memory device for preserving data copies. This segmentation allows efficient memory utilization where each segment serves a specific function, balancing data availability with resource consumption.
Solution Approach 2:
The ring buffer implements a discard and recover mechanism where older data is automatically overwritten when the buffer is full, but data is preserved in non-volatile memory for potential retrieval. This allows the system to maintain data availability for diagnosis while managing memory resources efficiently by discarding redundant data in the buffer while recovering stored data when needed for transmission.
Data Source
AI summary
An operation data support system for industrial machinery includes a first memory, a second memory, a communication device, and a control device. The first memory stores, with a ring buffer, operation data regarding a backhoe. The second memory is different from the first memory and stores operation data. The communication device transmits, outward from the backhoe, the operation data stored in either the first memory or the second memory. The control device controls the first memory, the second memory, and the communication device. When acquiring a transmission command for operation data, the control device stops storage of operation data with the ring buffer in the first memory and additionally causes the communication device to transmit first operation data stored in the first memory.
