Vehicle Sensor Data Quality Filtering for Backend Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for transmitting environmental data from transportation vehicles to backend computers often lack quality control, leading to the transmission of insufficient data without intelligent processing or plausibility checking.
Innovation Solution
A method and apparatus that generate quality parameters for sensor data, combine them with environmental data to form records, and transmit only headers to the backend for quality checking, ensuring that only data meeting predetermined standards are processed and stored, thereby optimizing data quality and reducing unnecessary network usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If all environmental data from transportation vehicles are transmitted to the backend without quality control, then the quantity of available data increases, but the quality of collected data deteriorates due to transmission of insufficient data
Solution Approach 1:
The patent applies preliminary action by performing quality assessment of environmental data before transmission to the backend. The transportation vehicle evaluates the quality of sensor data locally and only transmits data that meets predetermined quality criteria, preventing low-quality data from consuming backend resources while maintaining data reliability.
Solution Approach 2:
The patent introduces an intermediary quality assessment mechanism between the data source (transportation vehicle sensors) and the backend system. This intermediary layer filters and evaluates data quality, allowing only high-quality data to proceed to the backend, thus resolving the contradiction between data quantity and quality.
2Reliability
If quality checking and intelligent processing are performed at the backend, then the quality of collected data improves, but the complexity of the backend system increases
Solution Approach 1:
The patent extracts the quality assessment function from the backend system and relocates it to the transportation vehicle. By taking out the complex quality evaluation process from the backend and performing it locally at the data source, the patent maintains high data quality while reducing backend system complexity.
Solution Approach 2:
The transportation vehicle performs self-service quality assessment of its own environmental data before transmission. The vehicle independently evaluates data quality using local resources and criteria, eliminating the need for complex backend quality checking mechanisms while ensuring only high-quality data reaches the backend.
3Loss of information
If all environmental data are transmitted to the backend, then complete data records are available for analysis, but unnecessary network usage increases due to transmission of insufficient data
Solution Approach 1:
The patent performs preliminary quality assessment at the transportation vehicle before data transmission. By evaluating data quality in advance and filtering out insufficient data locally, the system ensures complete high-quality data records are available at the backend while minimizing unnecessary network transmission of low-quality data.
Solution Approach 2:
Instead of transmitting all generated environmental data, the patent applies partial action by selectively transmitting only the high-quality subset of data that meets predetermined criteria. This partial transmission approach maintains data record completeness for analysis while significantly reducing network usage compared to transmitting all data.
Data Source
AI summary
A method and apparatus for transmitting vehicle-based environmental data relating to at least one transportation vehicle traveling on a predefined road section to a backend for the purpose of collecting data records relating to the road section. The method generates data relating to the environment of the transportation vehicle by an environment sensor system; generates quality parameters relating to the sensors in the environment sensor system, wherein the quality parameters enable a statement regarding the performance of the sensors; combines the quality parameters and the measurement data to form a data record and creating a summary relating to the data record; transmits the header to the backend; checks the quality parameters of the header; and rejects the header in response to the quality parameters not complying with a predetermined quality standard or retains the header for further processing in response to the quality parameters complying with the predetermined quality standard.
