Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for monitoring operating parameters in passenger transport installations, such as elevators and escalators, place high demands on monitoring units and data communication, requiring continuous or frequent data transmission and processing, which can lead to data bottlenecks and increased costs.
Innovation Solution
A method and device that utilize a network of sensors where triggering and data transmission occur only when specific predetermined characteristics are detected, allowing sensors to initiate measurements and signal processing remotely, reducing the need for continuous data processing and transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous or frequent data transmission and processing is used to monitor operating parameters, then monitoring quality and reliability are improved, but data processing burden and transmission costs increase
Solution Approach 1:
The patent implements periodic triggering of sensors based on detected characteristics. Instead of continuous monitoring, the system triggers sensor measurements and data transmission only when specific conditions are met (e.g., when a sensor detects a characteristic that warrants further investigation). This periodic action reduces data processing burden while maintaining monitoring reliability for critical events.
Solution Approach 2:
The system uses detected characteristics to automatically trigger further measurements and data transmission without requiring continuous external control. The monitoring device evaluates detected characteristics and autonomously decides when to activate sensors and transmit data, reducing the processing burden on central systems while maintaining effective monitoring.
2Reliability
If continuous data transmission is used to monitor operating parameters, then monitoring quality is improved, but data transmission costs and communication bandwidth requirements increase
Solution Approach 1:
The system transmits data periodically based on triggering conditions rather than continuously. Sensors are activated and data are transmitted only when specific characteristics are detected, significantly reducing communication bandwidth requirements and transmission costs while maintaining monitoring quality for critical events.
Solution Approach 2:
The patent extracts and transmits only the necessary data when triggering conditions are met, rather than continuously transmitting all sensor data. This selective data extraction reduces transmission volume and costs while maintaining the quality of monitoring for important operating parameters.
3Productivity
If a network of sensors with triggering mechanisms is implemented, then data processing efficiency is improved, but device complexity and initial costs increase
Solution Approach 1:
The system segments the monitoring function into distributed sensor nodes with local processing capability. Each sensor can evaluate its own characteristics and trigger measurements locally, reducing the complexity of central processing systems while improving overall data processing efficiency through distributed intelligence.
Solution Approach 2:
The system performs preliminary evaluation of detected characteristics at the sensor level before triggering data transmission. This preliminary action filters and pre-processes data locally, reducing the complexity of subsequent central processing and improving overall system efficiency.

AI summary
A method and a device monitor operating parameters in a passenger transport installation, such as an elevator or an escalator, having a plurality of sensors detecting different operating parameters and a signal processing device. The method steps include: repeatedly detecting a first operating parameter with a first of the sensors; triggering a second of the sensors as soon as the first operating parameter assumes a predetermined trigger characteristic; detecting a second operating parameter with the second sensor and transmitting a signal reproducing the detected second operating parameter to the signal processing device in response to the triggering; and processing the signal in the signal processing device or an external monitoring device for monitoring the second operating parameter. The method and device reduce a data processing amount and/or a data transmission amount, reduce a need for wiring and achieve complex sensor functions with the simple sensors that cooperate with one another.
