Movable Body Monitoring Apparatus Data Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle systems are unable to effectively acquire and process movement data from a large number of movable bodies, including non-support vehicles, leading to inefficient data processing and potential vehicle immobilization due to memory shortages and excessive reactivity.
Innovation Solution
A movable body monitoring apparatus that acquires, stores, and manages movement data from both support and non-support vehicles, using a transmitter, receiver, detector, and determining unit to validate and delete data when a non-support vehicle has passed, allowing for efficient data management and vehicle control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If movement data from non-support vehicles is continuously stored in memory, then the quantity of available movement data increases, but memory shortages occur leading to vehicle immobilization
Solution Approach 1:
The system automatically discards movement data of non-support vehicles that have passed by, based on detection data from detectors. This prevents memory overflow while maintaining data availability for relevant vehicles, resolving the contradiction between storing sufficient data and avoiding memory shortages.
Solution Approach 2:
The system dynamically manages movement data by continuously updating which data to retain and which to discard based on real-time detection of vehicle passage. This dynamic approach allows the system to adapt memory usage to current traffic conditions, preventing immobilization while maximizing data utility.
2Loss of information
If movement data from all movable bodies is acquired and processed, then the completeness of traffic information improves, but processing complexity and time increase causing excessive reactivity
Solution Approach 1:
The system extracts and processes only the essential elements of movement data - specifically tracking whether non-support vehicles have passed by using detector data. By focusing on this critical information rather than processing all movement data in detail, the system maintains information completeness for safety decisions while dramatically reducing processing time and reactivity issues.
3Measurement precision
If detection data is continuously monitored for all movable bodies, then the accuracy of passing detection improves, but the complexity of data management increases
Solution Approach 1:
The system segments data management by creating separate handling pathways for support vehicles (which transmit their own data) and non-support vehicles (which require detection-based tracking). This segmentation simplifies the overall management complexity while maintaining high detection accuracy through dedicated detection protocols for each category.

AI summary
A movable body monitoring apparatus is configured to receive movement data related to movements of a movable body. The apparatus includes an acquiring unit, a memory, a detector, and a non-support managing unit. The acquiring unit acquires movement data on a non-support movable body from a support movable body. The memory stores and records the acquired movement data. The detector detects passing of a movable body from the host vehicle. The non-support managing unit manages the movement data on the non-support movable body recorded in the memory. When it is determined that the non-support movable body the movement data on which has been recorded in the memory has passed by based on detection data by the detection of the detector, the non-support managing unit invalidates or deletes the movement data on the non-support movable body from the memory on a movable-body by movable-body basis.
