1. What problem does the defect trend feature solve?
The platform maps defect data from all inspection rounds onto the 3D model to form a spatial distribution view of defects; combined with multi-period comparison, it presents defect type composition, quantity changes and the progression of individual defects (such as changes in crack length and width), integrating scattered inspection records into readable, traceable trend information.
2. How does the defect trend support decisions?
Through the trend view, maintenance personnel can determine which defects are expanding and which areas need priority treatment, enabling rational allocation of maintenance resources and treatment plans. Specific feature items and display forms are subject to the actual platform version.
3. Applicable scenarios for the defect trend feature
| Scenario | Purpose |
|---|---|
| Defect distribution overview | Understand spatial distribution of bridge defects |
| Defect trend assessment | Identify expanding defects |
| Maintenance priority | Support treatment decisions |
4. Applicable conditions and scenarios
- Managed bridges with multi-period inspection data
- Maintenance agencies needing trend assessment and maintenance priority
- Specific capabilities subject to platform demo and test account
5. Notes
Defect trend analysis relies on multi-period data accumulation; a single inspection cannot show trends. A routine inspection data mechanism is recommended.
