Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual troubleshooting and analysis methods are used for elevator communication module faults, then human expertise can diagnose complex issues, but the fault detection time is extended and user experience is impaired
Solution Approach 1:
The system enables self-service fault detection by automatically monitoring communication module status through pre-set thresholds and generating fault alerts without requiring manual intervention. The monitoring module continuously checks communication parameters and automatically determines when faults occur based on pre-configured criteria, allowing the system to serve itself in detecting and reporting issues.
Solution Approach 2:
The system performs preliminary action by pre-setting fault determination thresholds and monitoring criteria before faults occur. The monitoring module is configured with advance thresholds for communication parameters, and the system proactively checks these parameters continuously, enabling early fault detection before actual communication failures impact user experience.
2Adaptability or versatility
If advanced networked technologies and intelligent modules are added to elevators, then scheduling flexibility and user convenience are improved, but system complexity increases making faults harder to detect
Solution Approach 1:
The monitoring module acts as an intermediary between the complex communication module and the control system. It simplifies the complexity by providing a dedicated intermediate layer that specifically monitors communication parameters, isolating the complexity of the communication module from the main control system while enabling focused fault detection without requiring the entire system to become more complex.
3Loss of information
If manual fault analysis and troubleshooting are performed, then comprehensive understanding of the fault can be achieved, but manpower and time resources are consumed
Solution Approach 1:
The system implements feedback by continuously monitoring communication parameters and automatically comparing them against pre-set thresholds. When parameters deviate from normal ranges, the system provides immediate feedback through fault alerts and notifications to the control system or maintenance personnel, eliminating the need for manual fault analysis while maintaining complete fault information through automated recording and reporting.

AI summary
Methods and systems for monitoring an elevator communication module fault, and elevator systems. The method for monitoring an elevator communication module fault includes acquiring a feedback result in response to sending requests from one or more client ends to the elevator communication module, the elevator communication module being provided for having near-field wireless communication with a client end; counting the number of request failures in the feedback result within a pre-set duration; judging whether the countered number of request failures is not less than a pre-set threshold, and if yes, determining that the elevator communication module has a fault. The invention can quickly and efficiently detect the elevator communication module that has failed, improve elevator passengers' experience, and ensure that the elevator is in excellent operation condition and has a reliable safety performance.
