Sensor Data Filtering for Resource-Efficient Wireless Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for exchanging sensor data between vehicles in collective perception systems lose essential information due to resource-intensive communication of raw data, leading to inefficient data transfer and potential loss of critical information.
Innovation Solution
A method and device for processing sensor data that involves reducing and filtering data based on specified properties, such as compression and resolution, to transmit only relevant information efficiently over wireless communication systems, using filter rates to determine the extent of data reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensor data is transmitted without filtering or reduction, then data integrity and completeness are maintained, but communication load and resource consumption increase significantly
Solution Approach 1:
The patent applies preliminary action by filtering and reducing sensor data before transmission. The receiving device sends a request specifying desired properties, and the sending device pre-processes the data accordingly, performing the filtering action before the data leaves the source device. This resolves the contradiction by maintaining data integrity for requested properties while reducing overall communication load through selective pre-processing.
Solution Approach 2:
The patent implements local quality by applying different filtering strategies to different portions of sensor data based on requested properties. Rather than uniformly processing all data, the system selectively filters data according to specific quality requirements (e.g., temporal resolution, spatial resolution, spectral resolution) requested by the receiving device, optimizing communication efficiency while maintaining necessary data integrity.
2Productivity
If sensor data is filtered and reduced based on requested properties, then communication efficiency improves and resource consumption decreases, but data completeness may be compromised
Solution Approach 1:
The patent employs feedback by having the receiving device send a request that characterizes desired properties of the sensor data. This feedback loop allows the sending device to understand exactly what quality attributes are needed (e.g., temporal resolution, spatial resolution) and adjust the filtering accordingly. This resolves the contradiction by ensuring data completeness for requested properties while improving communication efficiency through targeted filtering.
Solution Approach 2:
The patent applies dynamics by making the filtering process adaptive and flexible. The filtering parameters are not fixed but are dynamically adjusted based on the received request characteristics. The system can change its processing behavior in real-time according to different quality requirements, resolving the contradiction between communication efficiency and data completeness by adapting the reduction level to actual needs.
3Measurement precision
If all sensor data properties are transmitted with high resolution, then measurement precision is maintained, but data volume and transmission resources increase
Solution Approach 1:
The patent implements local quality by applying different resolution levels to different properties of sensor data based on requests. Rather than uniformly transmitting all data at high resolution, the system selectively maintains high resolution only for requested properties (e.g., temporal resolution for moving objects, spatial resolution for specific regions) while reducing resolution for other properties. This resolves the contradiction by maintaining measurement precision where needed while reducing overall data volume.
