Data Logger Standardized Format Secure Raw Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data loggers require hardware-specific evaluation software to display measurement data remotely, making it time-consuming and prone to qualitative issues, as direct graphic or tabular display at a location away from the data logger is only possible if the connected system is equipped with the necessary software.
Innovation Solution
A data logger with interconnected function blocks, including an analog/digital converter, memory unit, timer, processor unit, and input/output interfaces, that converts data into a standardized format compatible with general software, allowing graphic and tabular display on any PC, while embedding raw data securely for access only with hardware-specific software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data loggers use hardware-specific evaluation software for remote display of measurement data, then data security and authorized access are improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent divides data access into two segments: protected raw data that requires hardware-specific software for access, and processed/evaluated data that can be displayed through standardized interfaces. This segmentation allows simultaneous provision of secure data protection and ease of operation for authorized users.
Solution Approach 2:
The patent introduces an intermediary processing layer that converts raw measurement data into standardized formats for display while maintaining the original protected data. This intermediary layer enables remote display through standard software without compromising the security of the underlying data.
2Reliability
If data loggers require hardware-specific evaluation software for remote data display, then data security is improved, but loss of time and productivity worsen
Solution Approach 1:
The patent performs preliminary processing of measurement data into standardized formats during the data acquisition phase. This preliminary action enables immediate display and evaluation using standard software without requiring time-consuming post-processing or specialized software installation at remote locations.
3Ease of operation
If data loggers use standardized data formats for remote display, then ease of operation and productivity are improved, but manufacturing precision and data protection worsen
Solution Approach 1:
The patent embeds protected raw data within a standardized data structure, creating a nested format where the outer layer provides standard compatibility while the inner layer maintains precise, protected data. This allows standardized software to access processed data while the original precise data remains secured.
Data Source
AI summary
A data logger is disclosed wherein a common housing includes different function blocks which are connected to one another. These function blocks include at least one analog/digital converter for conversion of measurement signals into digital input data, a memory unit for recording of digital data and of digitized event data, a timer, a processor unit for processing of data, a power supply source and input and output interfaces for measurement signals or digital data and event data. The processor unit is configured for conversion of digital input data and time data into a format which is compatible with standardized software (e.g., freely available) and which makes it possible to display the processed data using standardized software in tabular and/or graphic form on an output device. The processor unit can be configured to embed the digital input data and time data as well as the event data as protected raw data into the generated data format such that they can be read and processed only with hardware-specific evaluation software.
