Real-Time Output Signal Adjustment in Device Maintenance Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional device maintenance methods in plants and facilities are inefficient due to fixed test patterns, which cannot adapt to changing conditions, leading to prolonged test times and difficulties in checking output levels within set intervals, especially when multiple devices are involved or when different output levels are required.
Innovation Solution
A device maintenance apparatus that allows for real-time adjustments to the output signal's progress and value during testing, including forwarding, returning, maintaining, and changing instructions, enabling operators to modify the test pattern without waiting for predetermined intervals, thereby improving operational efficiency and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed test pattern is used for device maintenance, then the test procedure is simple and standardized, but the test time is prolonged and cannot adapt to changing conditions
Solution Approach 1:
The test pattern is transformed from a fixed, static sequence to a dynamic, adjustable sequence that can be modified in real-time during execution. Operators can change the progress and output values based on actual device conditions, allowing the system to adapt to varying maintenance needs without restarting the entire test pattern.
Solution Approach 2:
The invention allows changing key parameters of the test pattern (progress position and output signal values) during execution. This enables rapid adaptation to different device states or maintenance requirements by adjusting test parameters on-the-fly rather than following a rigid predetermined sequence.
2Measurement precision
If a fixed test pattern with predetermined intervals is used, then the test structure is simple, but it is difficult to check output levels within set intervals when multiple devices are involved
Solution Approach 1:
The test pattern allows dynamic adjustment of progress and output values during execution. When multiple devices are tested, operators can modify the test progression to accommodate different device characteristics and check output levels at appropriate intervals for each device without following a rigid uniform schedule.
3Productivity
If the test pattern cannot be modified during execution, then the test procedure is straightforward, but operational efficiency is reduced due to inability to respond to changing conditions
Solution Approach 1:
The test system transitions from a static, unchangeable pattern to a dynamic pattern that accepts modifications during execution. Operators can input change instructions to adjust progress and output values in real-time, improving maintenance efficiency by responding to actual device conditions while maintaining relatively simple operation through an intuitive interface.
Solution Approach 2:
The system incorporates feedback mechanisms where test execution results and device conditions inform subsequent test adjustments. Operators receive information about device state and can modify the test pattern accordingly, creating a responsive maintenance process that adapts to actual conditions rather than forcing devices into a rigid test framework.

AI summary
A device maintenance apparatus includes a test executor configured to cause a device to output an output signal based on a test pattern that changes the output signal output from the device with an elapse of time, and a change instructor configured to issue a change instruction for changing at least one of a progress of an output of the output signal based on the test pattern and an output value of the output signal to the test executor in accordance with an instruction input while the test executor causes the device to execute the output of the output signal.
