Data Characteristics for This Category
Marketing data for construction machinery mainly comes from manufacturer official product manuals, financial leasing marketing documents for construction machinery from financial institutions, technical parameter specifications, sales quotation documents, and after-sales maintenance manuals. Data update rhythm adjusts alongside new product launches, configuration iterations, or compliance requirements, with no fixed cycle. Document structures center on core complete machine parameters, model specifications, parts details, operation guides, and key financial plan modules. Fields include rated lifting capacity, maximum operating radius, fuel consumption rate, monthly payment amount, down payment ratio, and more. Most units follow metric standards, such as tons, meters, liters per hour, and kilowatts. Financial fields use units like percentage and yuan.
Constraints on Forms and Interactions
The multi-parameter, multi-unit, and long-document nature of construction machinery data, combined with financial marketing requirements, creates multiple constraints for forms and interactions. Diverse units for core parameters and financial fields require form input fields to include preset unit options or automatically bind unit suffixes, to prevent user input format errors. Demand to parse long document content requires forms to support batch uploading of multi-page product manuals and financial plan documents, and automatically extract core parameters and key financial points. Demand matching logic for marketing scenarios requires forms to use scenario-linked interactions. The system automatically filters financial plan options for corresponding models based on user-input operating scenarios, operating height and other equipment parameters, reducing manual entry costs. Some users upload on-site equipment photos or working condition images for demand communication, so forms must support image upload functionality.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_IMAGE_MAX_SIZE | 5–10 MB | Construction machinery-related on-site equipment and working condition photos have high resolution. 5–10 MB covers most high-definition shooting needs, while avoiding upload timeouts caused by oversized files. |
PARSE_DOC_MAX_LENGTH | 800–1200 characters | Core parameter paragraphs of construction machinery technical documents are mostly 800–1200 characters. This segment length fully retains parameter-related information and avoids losing context after splitting. |
RECALL_TOP_K | Top 3–5 entries | Core parameter entries for construction machinery marketing content are limited. Too many recall results increase model processing burden. 3–5 entries cover core matching needs. |
FORM_FIELD_UNIT_AUTO_BIND | Enabled | Construction machinery parameters have diverse and fixed units. Automatic binding reduces user input errors and improves form filling efficiency. |
UPLOAD_FILE_TIMEOUT_SECONDS | 300 seconds | Large construction machinery product manuals are often dozens of pages of PDF. 300 seconds meets the needs of complete upload and parsing of large files. |
FORM_SCENE_LINKAGE_ENABLE | Enabled | Construction machinery financial marketing requires matching operating scenarios and model parameters. Scenario linkage simplifies the user's filling process. |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: Form images fail to recognize parameters normally, or upload progress gets stuck. Cause: The
UPLOAD_IMAGE_MAX_SIZEparameter is not configured correctly, causing images exceeding the limit to be blocked or fail to parse. - Phenomenon: After importing construction machinery documents into the knowledge base, the number of retrieval results is abnormally too few or too many, and the response speed is slow. Cause: The
PARSE_DOC_MAX_LENGTHsetting is unreasonable. Too short splitting leads to loss of parameter context, while too long setting leads to reduced retrieval matching accuracy and increased processing time. - Phenomenon: When importing multi-page construction machinery PDF documents, the front-end page keeps refreshing and cannot select the target page. Cause: The
UPLOAD_FILE_TIMEOUT_SECONDSparameter is not adjusted, and large file parsing timeout causes abnormal front-end loading status.
How to Verify Successful Configuration
- Upload a standard-sized construction machinery on-site photo, check that the upload progress completes normally with no error prompts.
- Import a small construction machinery product manual document, check that the parsed segments fully retain core parameter information with no obvious truncation or splitting errors.
- Select a preset operating scenario when filling out the form, check that the corresponding model parameters and financial plan options are automatically loaded without requiring manual entry of additional information.
- Submit the form and trigger knowledge base retrieval, check that the matching degree of returned results meets expectations with no excessive redundant content.
