Measuring Instrument Diagnostics for Remote Fault Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for restoring normal measuring behavior in measuring instruments require on-site service interventions, which are time-consuming and inconvenient, especially when deviations occur during long measurement programs, and often necessitate unwanted access to user data processing systems.
Innovation Solution
A diagnostic measurement program is implemented in the measuring instrument that requests user input on operating conditions, executes the program, stores data, and prepares it for remote transmission to a service entity, allowing for remote diagnosis and service planning without user location visits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a service technician performs on-site investigation using special software maintenance tools, then accurate diagnosis can be established, but transporting the measuring instrument to the service entity location or vice versa is required
Solution Approach 1:
A portable service entity device is introduced as an intermediary that can be transported to the user location. This device communicates with the measuring instrument via a communication interface, enabling remote diagnosis without requiring transport of the main measuring instrument. The intermediary device fetches measurement data and transmits diagnostic information, resolving the contradiction between accurate diagnosis and transport time.
2Object-affected harmful factors
If remote servicing is performed without accessing user data processing systems, then user data security is maintained, but the service entity lacks necessary access to diagnose measurement deviations
Solution Approach 1:
The system is segmented into separate functional components: the measuring instrument that generates measurement data, the user data processing system that maintains data security, and the portable service entity device that performs diagnosis. The service device communicates only with the measuring instrument's measurement data, not the user's data processing system, enabling service accessibility while maintaining user data security through architectural separation.
3Measurement precision
If the service entity observes the complete measurement program runtime to detect deviations, then accurate fault identification is achieved, but the observation period becomes equally long with correspondingly high idle time
Solution Approach 1:
The measuring instrument is equipped with a built-in diagnostic program that automatically executes during measurement operations and continuously monitors measurement data for deviations. This preliminary action detects faults in real-time without requiring the service entity to observe the entire measurement program runtime, thereby maintaining fault detection accuracy while eliminating service entity idle time and improving productivity.
Data Source
AI summary
A method, as applied to a program-controlled measuring instrument, determines an observable property of an object. The program-controlled measuring instrument has a diagnostic measurement program that is executed by a user. The diagnostic measurement program stores data related to the execution of the diagnostic measurement program and maintains the data for remote transmission to a remote service entity.
