Test System Mode-Specific Operating Time Accumulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional test systems for mobile bodies and their components fail to accurately accumulate operating periods of components across different operational modes, leading to inaccurate operational check and maintenance management.
Innovation Solution
A test system with a history-information acquiring unit that accumulates operating time only in predetermined operational modes for each component, using a device-managing device to manage and display operating history, allowing for precise tracking and warning generation based on component lifetimes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If operating time of components is uniformly accumulated across all operational modes, then the accumulation process is simple, but the operating period cannot be accurately accumulated because components do not actually operate in all modes
Solution Approach 1:
The patent segments the operational modes into multiple categories (measurement mode, calibration mode, purge mode, measurement+purge mode) and assigns different accumulation rules to each mode. The history information acquiring unit accumulates operating time separately for each component based on its specific operational mode, rather than uniformly across all modes. This segmentation enables accurate tracking of when components actually operate versus when they are idle or performing maintenance functions.
2Adaptability or versatility
If multiple operational modes are supported with different component operations, then the system is versatile, but it becomes difficult to accurately track which components are actually operating
Solution Approach 1:
The patent implements a feedback mechanism where the history information acquiring unit continuously monitors the current operational mode and the state of each component, then updates the accumulated operating time accordingly. The system receives feedback about which components are active in each mode and uses this information to selectively accumulate operating time only for components that are actually operating. This feedback loop ensures accurate tracking despite the complexity of multiple operational modes.
3Reliability
If operating history is not accurately tracked, then maintenance scheduling is simple, but component lifespan management and operational check timing cannot be properly managed
Solution Approach 1:
The patent enables the system to automatically manage its own maintenance scheduling by having the history information acquiring unit continuously accumulate and track operating hours for each component based on actual operational modes. The system self-monitors component lifetimes and can automatically determine when maintenance or operational checks are needed, eliminating the need for manual tracking while ensuring accurate maintenance timing. This self-service approach maintains reliability without significantly complicating operation.

AI summary
According to the present invention, a test system 1 that tests a mobile body such as a vehicle, a vessel, and a plane, or an instrument used in the mobile body as an object, and is operable by switching among different operational modes, can accumulate an operating period of a component much more accurately than conventional system, and includes an accumulated operating-time calculating unit 46 for accumulating the operating time of the component, and the accumulated operating-time calculating unit 46 accumulates the operating time of the component only in the predetermined operational mode.
